Abstract
In the context of an increasingly egalitarian society, in which all genders are encouraged to be vocal about their goals and take equal growth opportunities, goal interdependence in couples has been repeatedly associated with relationship satisfaction. The aim of this meta-analysis was to provide evidence for the association between goal interdependence and relationship satisfaction in couples. We performed a random-effects analysis for the 32 reports and 49 independent samples that investigated three types of goal interdependence (goal support, goal congruence, and goal conflict) in association with relationship satisfaction. We found significant medium effect sizes between goal interdependence in general (r = .23) and relationship satisfaction, as well as between each type of goal interdependence and relationship satisfaction. The strongest effect size emerged for the association between goal congruence and relationship satisfaction (r = .43), followed by the association between goal support and relationship satisfaction (r = .28) and by the negative association between goal conflict and relationship satisfaction (r = −.29). From a theoretical standpoint, these results provide support for a key claim from the Transactive Goal Dynamics Theory that goal coordination between partners impacts relationship functioning. From a practical standpoint, they emphasize the need to consider goal interdependence in couples’ therapy, particularly in the current sociocultural context.

Introduction
With 40% of marriages ending in divorce (National Center for Health Statistics, 2012) and relationship problems being the most common reason for seeking formal counselling (Swindle et al., 2000), identifying predictors of relationship satisfaction is paramount. Recently, goal dynamics or interdependence have become an intensely researched topic in the realm of romantic relationships. In the context of an increasingly egalitarian society, in which all genders are encouraged to be vocal about their goals and take equal growth opportunities, dynamics between these goals are bound to relate to couples’ relationships, including their satisfaction with the relationship and probability for divorce (Gere et al., 2016).
Research in the past decades consistently supports the importance of goal pursuit for people’s wellbeing (Bernecker & Becker, 2021). Recent studies emphasize that regulation in goal pursuit and its associated positive outcomes are not only individually determined, but also highly influenced by significant others, such as romantic partners, who can either facilitate or hinder personal goal processes (Fitzsimons & Finkel, 2018). This interaction is called goal interdependence and is shown to be further associated not only with goal processes, but also with relationship-related outcomes (Cappuzzello & Gere, 2018; Koestner et al., 2012). Despite evidence suggesting that goal interdependence (particularly goal support) is related to positive outcomes both for the individual and the relationship (Gere et al., 2011; Koestner et al., 2012), previous research findings have been mixed. For example, some studies have found either non-significant or even negative associations between goal interdependence and positive relationship outcomes, such as the quality of marital interactions or relationship satisfaction (e.g., August et al., 2013; Carbonneau et al., 2019). These mixed findings underlie the need for a meta-analytic investigation to put together existing evidence and shed light on the intricate associations between goal interdependence and relationship satisfaction. One reason that has been advanced for these mixed results is the existence of different types of goal interdependence, with consequently differential associations with relational outcomes (Vowels & Carnelley, 2020). Therefore, our meta-analysis investigates three types of goal interdependence – goal support, goal congruence, and goal conflict – and its associations with relationship satisfaction. Of these types of goal interdependence, goal support is currently the most widely investigated. However, interest in goal congruence and goal conflict also increases due to their apparent relevance for couples’ wellbeing (Gere & Impett, 2017).
Goal support refers to instrumental or emotional help or contributions that people receive from their partners to set, pursue, and achieve their goals. For example, when Partner 1 wants to advance in their career, Partner 2 supports them by doing more household tasks. Goal congruence refers to partners who share or have similar goals for themselves (Fitzsimons & Finkel, 2018). For example, both Partner 1 and Partner 2 want to pursue successful careers. Goal congruence can also refer to situations in which both partners share a certain goal for one partner. Possessing a goal for one’s partner that is also shared by the partner means having congruent goals; however, pursuing this goal for your partner (i.e., making efforts to facilitate progress towards it) is a form of goal support (Fitzsimons & Finkel, 2018). For example, both Partner 1 and Partner 2 want Partner 1 to gain more money, so they share a similar/congruent goal. As a result, Partner 2 performs daily searches on hiring platforms to find a better job for Partner 1, which is rather a form of instrumental support for the latter. Goal conflict refers to incompatibility or interference between couples’ goals (Gere & Schimmack, 2013). For example, Partner 1 wants to invest more time to improve his relationship with Partner 2, but Partner 2 wants to invest more time in their career.
Meta-analytical results regarding the association between these types of goal interdependence and relationship satisfaction could provide insights in conceptualizing goal interdependence and providing a more coherent picture on how goal interdependence relates to romantic relationships. Despite the growing number of studies in the field, to our knowledge, no meta-analysis so far has investigated the association between goal interdependence and relationship functioning. Therefore, the current study will meta-analytically investigate the relationship between goal interdependence and relationship satisfaction in couples, as well as how particular types of goal interdependence differentially relate to relationship satisfaction. More specifically, we expect goal support and goal congruence to be positively associated with relationship satisfaction, and goal conflict to be negatively associated with relationship satisfaction. The rationale for these expectations will be detailed below.
Theoretical background
Transactive Goal Dynamics Theory (TGD; Fitzsmons & Finkel, 2018) provides a more coherent explanation for the association between goal interdependence and relationship satisfaction. TGD emerged in an attempt to explain goal interdependence in social systems (i.e., two or more interrelated people) and its effects on relationship functioning. According to the theory, people’s self-regulation processes aimed at setting, pursuing, and achieving goals do not work in isolation, but are influenced by other members of the social system. Thus, the social system becomes a single self-regulating unit, instead of two or more individual/isolated units, in which the way one member of the social system regulates their own behaviour, emotions etc., inherently impacts other members’ goal-related regulation processes. The closer the members of the social system are, the more interdependent their goal dynamics will be. This goal-related interdependence is named transactive density and is especially strong in social systems characterized by frequent interactions and strong motivation for goal-relevant interdependence (e.g., couples etc.; Finkel et al., 2016).
When the social system, in this case, the couple, properly coordinates its goals (through similar goals, low interference with partners’ goals, emotional or instrumental goal-support), partners experience transactive gain (i.e., better goal outcomes than they would have experienced on their own), which further strengthens their relationship (Finkel et al., 2016). In contrast, partners’ lack of support or goal conflict will lead to transactive loss (i.e., interference with progress in one’s own goal pursuit, giving up on personal goals for the sake of romantic partners’ goals; Finkel et al., 2016), which will increase frustration and negatively impact relationship persistence (Finkel et al., 2016).
In close relationships, goal-related interdependence, such as perceived partner goal-related support, joint engagement in physical activity goals, partner’s instrumental support for one’s goals or collaborative problem-solving have been related to greater commitment to the respective goal (Berli et al., 2018), higher goal progress (Briskin et al., 2019), as well as higher relationship satisfaction and overall wellbeing (Cappuzzello & Gere, 2018; Gere et al., 2011; Hoppmann & Gerstorf, 2013; Molden et al., 2009). However, in agreement with TGD, romantic partners’ influence on personal goals is not always beneficial for personal and relational wellbeing. For example, certain types of goal support (e.g., directive support) are either unrelated or negatively related to relationship satisfaction (Carbonneau et al., 2019; Koestner et al., 2012), potentially since being constantly monitored by one’s partner or offering permanent assistance for partners’ goals may feel demotivating and make partners question the similarity of their goals and values (Carbonneau et al., 2019). Kindt et al. (2020) also found that partners’ needs or goal conflict with personal goals (i.e., incompatible goals and goal pursuit strategies; Finkel et al., 2016) relate to lower life and relationship satisfaction. Similarly, the results of Gere and Schimmack (2013) show that constant interference between partners’ goals (especially for long-term goals) is associated with lower general and relationship wellbeing. These results suggest that goal interdependence in couples may differentially relate to relationship quality, depending on factors such as the type of interdependence or how partners’ goals interact with each other.
Past meta-analyses in the domain of goal interdependence in couples have generally focused on one form of goal interdependence (i.e., goal-related support; Vowels & Carnelley, 2020) and its association with goal outcomes, such as goal pursuit, motivation, and progress (Park et al., 2004; Pilkington et al., 2015). However, research shows that goal interdependence is not only related to goal outcomes per se, but also to relationship outcomes, such as relationship commitment or relationship wellbeing (Gere, 2012) and that its associations with relationship outcomes are tightly linked to the specific type of goal interdependence (Gere & Schimmack, 2013). As such, the current meta-analysis separately investigates the association of three types of goal interdependence (i.e., goal support, goal congruence, and goal conflict) with relationship satisfaction.
Measures for goal interdependence
Measurements are specific to the type of goal interdependence targeted by each study. Measures for goal support vary widely depending on whether the study addresses one particular goal for all the participants (e.g., quitting smoking) or different goals that participants report. In the first situation, instruments specific to a certain goal are used in general, such as the Partner Interaction Questionnaire (Cohen & Lichtenstein, 1990), which assesses partner support for the goal of quitting smoking. In the second case, participants are asked to name or think about certain goals and then assess perceived partner support on the goals they reported – e.g., “My partner gave me advice about my goals” (Jakubiak & Feeney, 2016), “Does your partner make it easier to pursue this goal?” (Cappuzzello & Gere, 2018). The current meta-analysis only includes studies which measure partner support that is explicitly related to a certain goal that their partner is pursuing. Specifically, studies should explicitly ask participants to refer to certain goals when assessing perceived support from their partner, as opposed to assessing partner support with no explicit reference to one or more goals, such as support for coping with stress (Falconier et al., 2015). Measures for goal congruence follow a similar trend to the ones for goal support, with specific measures for specific goals – e.g., Shared Goals and Values Scale (Archuleta et al., 2010) for assessing financial goals similarity in couples (Archuleta et al., 2013) and general assessment for general goals – e.g., by matching participants’ reported goals with similar or identical goals they perceive their partners have (Gere, 2012) or with the goals reported by their partners themselves (Riediger & Rauers, 2010). Measures for goal conflict tend to be more homogenous, with most studies asking participants to name some important goals that they pursue and assess whether and how frequently their pursuit of their own goals interferes with their partners’ (e.g., Gere & Impett, 2017).
Moderators
In order to account for particularities in the associations between goal interdependence and relationship satisfaction, we also tested for potential moderators. Firstly, we tested moderators that are traditionally investigated in meta-analyses (such as study design, sample size, female percentage in the sample, mean age). We considered two categories for study design: cross-sectional and longitudinal studies. Effect sizes coming from longitudinal studies are generally significantly smaller than cross-sectional ones due to the inherent nature of longitudinal analyses, which hold past effects on the outcome under control, thus reducing the effect size (Adachi & Willoughby, 2015).
Secondly, we tested two additional moderators that are generally investigated in couple studies or in the context of goal interdependence, i.e., goal type and relationship length. Goal type was divided into two categories: general and specific. With general goals, studies would usually ask participants to assess the perceived level of goal interdependence with respect to their personal goals in general (without naming the goal), whereas in studies focusing on specific goals, participants assessed goal interdependence in relation to a concrete goal (e.g., giving up smoking, losing weight etc.). Although it is possible for general goals to yield higher effect sizes since studies focusing on general goals are more similar in how they conceptualize and measure goal interdependence compared to studies focusing on specific goals, one meta-analysis focusing on the relationship between goal support and goal outcomes in couples found no significant differences for the two categories of goal type (Vowels & Carnelley, 2020).
Given the inconsistent findings for relationship length, we investigated it exploratorily. For example, although past meta-analyses on couples’ studies emphasize its relevance as a moderator, particularly when relationship satisfaction is considered (e.g., Hadden et al., 2014), Jakubiak and Feeney (2016) found that goal interdependence and relationship satisfaction are similarly related in samples of newlyweds and married couples in late adulthood. Moreover, Vowels and Carnelley did not find a significant moderator effect of relationship length on the association between goal support and goal outcomes.
The current study
Despite the growing number of studies investigating goal interdependence, to our knowledge no meta-analysis up to now investigated the extent of the association between goal interdependence and relationship satisfaction. From a theoretical standpoint, the present meta-analysis will quantify the extent to which results in the TGD domain support one of the main assumptions of the theory – i.e., that the proper mutual coordination of ones’ goals benefits the relationship, while goal conflict negatively affects the relationship (Finkel et al., 2016). From a practical standpoint, results could point to the importance of considering goal-related interdependence when targeting relationship quality in couple psychotherapy and identify the specific types of goal interdependence that should be addressed by the therapist.
Hypotheses
The aim of the current meta-analysis is thus twofold: a) to determine the strength of the relationship between goal interdependence and relationship satisfaction in couples and b) to determine how different types of goal interdependence relate to relationship satisfaction. Specifically, we hypothesize that goal congruence and goal support will be positively related to relationship satisfaction, while goal conflict will be negatively related to relationship satisfaction.
Regarding the moderators, we expect studies with longitudinal designs to report smaller effect sizes than studies with cross-sectional designs. The remaining moderators (i.e., sample size, mean age, female percentage, goal type, and relationship length) were investigated exploratorily, with no prior expectation regarding their impact on the overall effect size.
Methods
Literature search
In order to identify relevant studies for the current meta-analysis, we conducted a systematic search up to March 2021 in the following databases: PsychInfo, Web of Science, Scopus, PubMed/Medline, ProQuest Central and Google Scholar, with the following search string: (“goal conflict” OR “goal interference” OR “interference” OR “goal support” OR “support” OR “encourage*” OR “relational catalyst” “goal congruence”) AND (“relationship satisfaction” OR “relationship quality” OR “relationship wellbeing”) AND (“romantic” OR “partner” OR “dyad*” OR “intima*” OR “couple*“). We also searched for relevant references in previous theoretical papers on transactive goal dynamics (Fitzsimons & Finkel, 2018; Fitzsimons, Finkel, & Vandellen, 2015), as well as in the reference list of meta-analyses on this topic (e.g., Vowels & Carnelley, 2020). In order to identify unpublished papers, we performed searches on ProQuest, a database that includes unpublished data from doctoral and dissertation theses. We also emailed authors of published papers on goal interdependence and published calls on listservs (e.g., International Association for Relationship Research; Social Psychology Network) to ask for unpublished data. In an attempt to reach as many researchers as possible, we also contacted authors through private messages on the International Association for Relationship Research (IARR). Furthermore, we contacted authors of studies where the data that we needed for the meta-analysis, although measured, have not been reported. However, replies to our requests were not provided.
Titles, abstracts, and full texts were screened by A. T. and potential difficulties in the selection of certain studies were discussed with two other reviewers (I. R. P. and P. P. R.). Our search strategy resulted in a total of 17 372 articles. After the removal of duplicates, 16 600 reports were screened by title and abstract. Eventually, 150 full-text records were analyzed, with 118 reports being excluded and the remaining 32 meeting all the inclusion criteria. In the final meta-analysis, 32 reports, with 49 independent samples/studies were included. The whole search and selection process is detailed in the PRISMA flowchart (Figure 1). PRISMA flow diagram illustrating the study selection process.
Inclusion and exclusion criteria
In order to be included in the current meta-analysis, studies had to meet the following criteria: studies had to include participants in romantic relationships, studies should report interdependence in the context of romantic relationships, goals (no other types of stressors) should be the target of partners’ support, studies should specifically mention one goal (e.g., quit smoking) or general goals that participants pursue, studies should report data for the association between goal interdependence (i.e., goal support, goal conflict/interference, goal congruence) and relationship satisfaction, and either a cross-sectional or longitudinal design should be used. When both cross-sectional and longitudinal effect sizes were reported, we prioritized longitudinal effect sizes because they are considered more accurate (Adachi & Willoughby, 2015).
Exclusion criteria were: studies with experimental manipulations that might impact goal interdependence, goal interdependence in relation to persons other than romantic partners, partner support unrelated to participants’ goal(s) (e.g., emotional support during stressful times).

Statistical methods
Statistical analyses were performed with the Comprehensive Meta-Analysis Software Version 3 (Borenstein et al., 2013). Given that study and participants characteristics, as well as measures for the included variables differ across studies, a random-effects model was used be used for the effect size analyses (Borenstein et al., 2009). We extracted the r correlation or regression coefficients from each study and converted them to Fisher’s z scale. All analyses were performed using the transformed values, which were then converted back to correlation for presentation and interpretive purposes. In studies where two or more relevant effect sizes were reported for the association between goal interdependence and relationship satisfaction, we computed an average of these correlations. The interpretation of the effect sizes follows Cohen’s (1988) guidelines, i.e., r values of 0.10 or smaller indicate a small effect size, values in between 0.30 and 0.50 indicate medium effect sizes, and values of 0.50 and higher indicate large effect sizes.
We also performed heterogeneity tests, i.e., the Q statistic to determine if variations in effect sizes are due to other sources than random error (Borenstein et al., 2009) and the I 2 statistic to determine the percentage of variation across studies due to heterogeneity rather than chance (Higgins et al., 2003). A leave-one-out sensitivity analysis was also performed to weigh in on the impact of each study on the overall effect size (Borenstein et al., 2009). For the identification of publication bias, we will use both funnel plots and the Egger’s test of the intercept (Egger et al., 1997). If the asymmetry of funnel plots was significant, the Duval and Tweedie trim-and-fill procedure was also used. This procedure provides corrected effect sizes estimates that would be needed to have complete symmetry (Duval & Tweedie, 2000).
Subgroup analyses were performed for the extracted categorical moderators (study design and goal type) and meta-regression analyses for continuous moderators (sample size, age, percentage of females in the sample, and relationship duration).
Results
The current meta-analysis included 32 studies, with 40 independent samples and a total of 9153 participants. Table 1 presents the characteristics of the studies included in this meta-analysis. The average age was 34.41 years (SD = 16.77, range 19.2–70) and the average relationship length was 108.73 months (SD = 127.43, range 2.95–480). An average of 50.40% of the participants were female and approximately half of the couples were married (52%). Except for three studies, all samples included mixed-gender couples exclusively. We also extracted data on nationality/ethnicity, level of education, and percentage of students in the sample. However, given the fact that a high number of studies did not report such data and that reporting was inconsistent across studies, computations to determine potential sociodemographic trends were not performed. With respect to the methodological characteristics of the studies, 21 of them (52,5%) were longitudinal and the remaining 19 were cross-sectional. The most common type of goal interdependence was goal support (70%), followed equally by goal conflict (15%) and goal congruence (15%).
Total effect size for the associations between goal interdependence and relationship satisfaction
In order to compute the effect size for the current meta-analysis, we converted the r correlation coefficient into Fisher’s z scale and then converted the effect size back to Pearson’s r for presentation and interpretive purposes. First, we computed the pooled effect size of the association between all types of goal interdependence and relationship satisfaction. The random-effects model analysis revealed a positive correlation between goal interdependence and relationship satisfaction, r = .23, 95% CI [.14, .32], p < .001, which, according to Cohen’s guidelines (Cohen, 1988), indicates a small effect size. Effect sizes for each study are presented in Figure 2. The funnel plot (see Supplemental Material, Figure 6) and the Egger’s test of the intercept revealed no publication bias, with Egger’s intercept = 3.73 p = .13. Since no publication bias has been found, the trim-and-fill procedure (Duval & Tweedie, 2000) was not computed. Forest plot for the total effect size for the association between goal interdependence and relationship satisfaction.
Leave-one-out analysis revealed no major deviation from the overall effect size. The smallest effect size was r = .22 after the studies of Archuleta et al. (2013) and Leung and Law (2019) were removed. The highest effect size was r = .25, after removing the study of Gere and Schimmack (2011).
Study heterogeneity was significant, with Q (39) = 1022.04, p < .001 and I 2 = 96.18%. We therefore performed moderator analyses for the moderators described in the Introduction of the current paper.

Associations Between Types of Goal Interdependence and Relationship Satisfaction
Across studies, three types of goal interdependence emerged: goal support, goal congruence, and goal conflict. Given the fact that some studies included two or more of the three types of interdependence and, therefore, data did not meet the condition of independence, we could not perform subgroup analyses to test whether effect sizes differ as a function of the type of goal interdependence. However, we computed separate effect sizes for the association between each type of goal interdependence and relationship satisfaction. Given the small number of samples for the association between goal conflict and relationship satisfaction and goal congruence and relationship satisfaction, moderator analyses have only been performed for the association between goal support and relationship satisfaction. A higher number of samples both for goal congruence and goal conflict would have been needed to have relevant meta-analytical results for goal congruence and goal conflict as well.
Exploratorily, we also investigated whether there are significant differences between studies including dyadic data and studies including individual data. However, although 21 of the total number of studies included data from both partners, only 9 of these studies reported actor and partner effects specifically for the association between goal interdependence and relationship satisfaction. Therefore, the analyses below do not include effect sizes based on actor and partner data, since most of the dyadic studies did not report dyadic data on the association under investigation in the current meta-analysis.
These analyses revealed no significant differences between dyadic versus individual studies, with an effect size of r = .18, 95% CI [.04, .32] for dyadic studies, and an effect size of r = .29, 95% CI [.17, .40] for individual studies, Q (1) = 1.22, p = .26.
Goal support and relationship satisfaction
For the association between goal support and relationship satisfaction, a number of 30 samples and a total of 7338 participants were included in the analyses. The overall effect size for the association between goal support and relationship satisfaction is r = .28, 95% CI [.19, .37], p < .001, which, according to Cohen’s guidelines (Cohen, 1988), indicates a small effect size. Effect sizes for each study are presented in Figure 3. The funnel plot (see Supplemental Material, Figure 7) and the Egger’s test of the intercept revealed no publication bias, with Egger’s intercept = 3.87, p = .09. Since no publication bias has been found, the trim-and-fill procedure (Duval & Tweedie, 2000) was not computed. Forest plot for the association between goal support and relationship satisfaction.
Leave-one-out analysis revealed no major deviation from the overall effect size. The smallest effect size was r = .26 after the study of Leung and Law (2019) was removed. The highest effect size was r = .29, after removing the study of Martos et al. (2019).
Because study heterogeneity was significant, with Q (29) = 553.74, p < .001 and I 2 = 94.76%, we performed moderator analyses for the same moderators as above.

Results for the meta-regression analyses for continuous moderators showed no significant continuous moderation for the association between goal support and relationship satisfaction. Results of the meta-regression analyses for all the continuous moderators are presented in Table 3.
Goal congruence and relationship satisfaction
For the association between goal congruence and relationship satisfaction, a number of 6 samples and a total of 934 participants were included in the analyses. The overall effect size for the association between goal congruence and relationship satisfaction is r = .43, 95% CI [.22, .60], p < .001, which, according to Cohen’s guidelines (Cohen, 1988), indicates a medium effect size. Effect sizes for each study are presented in Figure 4. The funnel plot (see Supplemental Material, Figure 8) and the Egger’s test of the intercept revealed no publication bias, with Egger’s intercept = −0.61, p = .94. Since no publication bias has been found, the trim-and-fill procedure (Duval & Tweedie, 2000) was not computed. Forest plot for the association between goal congruence and relationship satisfaction.
Leave-one-out analysis revealed no major deviation from the overall effect size. The smallest effect size was r = .36 after the study of Archuleta et al. (2013) was removed. The highest effect size was r = .48, after removing the study of Riediger and Rauers (2010).
Although study heterogeneity was significant, with Q (5) = 85.71, p < .001 and I 2 = 94.16%, moderator analyses were not performed given the small number of samples.
Goal conflict and relationship satisfaction
For the association between goal conflict and relationship satisfaction, a number of 8 samples and a total of 1680 participants were included in the analyses. The overall effect size for the association between goal conflict and relationship satisfaction is r = −.29, 95% CI [-.44, −.14], p < .001, which, according to Cohen’s guidelines (Cohen, 1988), indicates a small to medium effect size. Effect sizes for each study, as well as for males and females if reported separately are presented in Figure 5. The funnel plot (see Supplemental Material, Figure 9) and the Egger’s test of the intercept revealed no publication bias, with Egger’s intercept = −1.26, p = .81. Since no publication bias has been found, the trim-and-fill procedure (Duval & Tweedie, 2000) was not computed. Forest plot for the association between goal conflict and relationship satisfaction.
Leave-one-out analysis revealed no major deviation from the overall effect size. The smallest effect size was r = −.25 after the study of Brunstein et al. (1996) was removed. The highest effect size was r = −.33, after removing the study of Gray and Cons (2017).
Although study heterogeneity was significant, with Q (7) = 96.794, p < .001 and I 2 = 92.76%, moderator analyses were not performed given the small number of samples.
Discussion
The current meta-analysis investigated the association between goal interdependence and relationship satisfaction, as well as between three different types of goal interdependence, i.e., goal support, goal congruence, and goal conflict on one side and relationship satisfaction on the other. Although some meta-analyses have examined the association between goal pursuit and general wellbeing (da Silva et al., 2016; van Genugten et al., 2017) or between partner goal support and goal progress (Vowels & Carnelley, 2020), no meta-analysis so far has analyzed how goal interdependence relates to relationship satisfaction. As partners’ role in times of thriving and growth (as opposed to their contribution merely in times of distress) becomes increasingly present in the scientific literature (e.g., Overall et al., 2010; Tomlinson et al., 2020; Vowels & Carnelley, 2020), the need to quantify the rapidly growing number of results also increased.
In our meta-analysis, we found significant small and medium effect sizes between goal interdependence in general and relationship satisfaction (r = .23), as well as between each type of goal interdependence and relationship satisfaction (r = .43 for goal congruence, r = .28 for goal support, and r = −.29 for goal conflict).
Goal interdependence and relationship satisfaction
The current meta-analysis shows that goal interdependence is generally positively related to relationship satisfaction. These results are consistent with the general assumption of the Transactive Goal Dynamics theory (TGD), which posits that interdependence of couples’ goals benefits the relationship when partners experience transactive gain (i.e., better goal outcomes than they would have experienced on their own) (Fitzsimons & Finkel, 2018). Similarly, a meta-analysis investigating the association between goal support and goal outcomes found that when people support their partners’ goals, partners experience better goal outcomes (Vowels & Carnelley, 2020). According to TGD, these positive goal outcomes have positive effects on the relationship when they are attributed to the relationship. Although TGD states that goal interdependence increases relationship commitment or persistence rather than relationship satisfaction (Finkel et al., 2016), literature shows that commitment is strongly related to relationship satisfaction (Madey & Rodgers, 2009). It is therefore legitimate to expect that goal interdependence is also related to relationship satisfaction, as our results have shown. Moreover, another meta-analysis has shown that the ability to pursue and achieve one’s goals improves one’s general wellbeing (da Silva et al., 2016). When goal pursuit and progress are partially attributed to one’s partner (due to goal interdependence), relationship wellbeing is also expected to improve.
Individual associations of goal support, goal congruence, and goal conflict with relationship satisfaction
Although goal interdependence was significantly positively related to relationship satisfaction, TGD states that not all types of goal interdependence are beneficial to the relationship (Finkel et al., 2016). Indeed, according to the theory, inconsistencies in partners’ goals or goal pursuit strategies may lead to transactive loss (i.e., interference with progress in one’s own goal pursuit; Finkel et al., 2016), which further affects the relationship. Therefore, we computed separate effect sizes for the three most researched types of goal interdependence, i.e., goal support, goal congruence, and goal conflict. All effect sizes were significant and moderate. The strongest effect size emerged for the association between goal congruence and relationship satisfaction (r = .43), followed by the association between goal support and relationship satisfaction (r = .35) and by the negative association between goal conflict and relationship satisfaction (r = .29). This may be explained by the fact that not all types of goal support are considered effective. For example, some studies have shown that directive goal support is actually negatively related or unrelated to relationship satisfaction (Carbonneau et al., 2019; Koestner et al., 2012). Brock and Lawrence (2009) have found that support under- and overprovision have negative effects on marriage quality, while Fivecoat et al. (2015) experimentally showed that partner passive (unlike active) support for self-expansion decreases relationship satisfaction. A meta-analysis by Falconier et al. (2015) also showed that dyadic coping (a form of supportive interaction between partners that is conceptually similar to, although broader than, partner support) can take forms that are actually detrimental to relationship quality. However, the identified differences between effect sizes should be interpreted with caution since our meta-analysis included a much higher number of samples for goal support (k = 30) compared to both goal congruence (k = 6) and goal conflict (k = 8).
The positive effect size for the association between goal support and relationship satisfaction is, however, reflective of the fact that most studies in the meta-analysis include positive types of support and that most individual studies identified positive associations between goal support and relationship satisfaction. According to the meta-analysis by Vowels and Carnelley (2020), partner goal support is positively associated with goal progress and TGD states that higher goal progress as a result of goal interdependence with one’s partner will also positively influence the relationship. This may explain why goal support is also positively related to relationship satisfaction, as shown in the current meta-analysis.
TGD states that not only goal support, but any type of goal interdependence that is bound to advance personal goals will benefit the relationship. This is in line with the positive effect sizes we identified for the association between congruence and relationship satisfaction as well (Fitzsimons & Finkel, 2018).
By contrast, we found that goal conflict is negatively related to relationship satisfaction. This supports TGD premises, which state that, if interdependence with one’s partner affects goal pursuit (as is the case with goal conflict), the relationship will also be affected (Fitzsimons & Finkel, 2018). Indeed, Vowels and Carnelley (2020) found moderate negative effect sizes for the association between negative support (i.e., partner’s interference with one’s goals, intrusion, and coercion) and self-efficacy in goal pursuit, which might explain the negative association between goal conflict and relationship outcomes (Finkel et al., 2016).
Moderators
No significant moderators emerged for the association between goal interdependence and relationship satisfaction. However, the differences in the effect size for cross-sectional versus longitudinal studies were in the expected direction, with longitudinal studies showing a lower (although not significant) effect size compared to cross-sectional ones. Indeed, longitudinal studies are known to typically produce smaller effect sizes because they often employ autoregressive models. Autoregressive models control for stability effects by using past values of the outcome and the correlation between the predictor at T1 and the outcome at T1 to predict future values of the outcome. This process automatically diminishes the effect size (Adachi & Willoughby, 2015). Adachi and Willoughby thus suggest that guidelines for interpreting effect sizes should be different for longitudinal and cross-sectional studies and that effect sizes coming from longitudinal studies that are normally considered trivial based on traditional thresholds might actually be highly relevant and comparable with significant effect sizes obtained cross-sectionally.
The remaining moderators were investigated exploratorily. Results showed that goal type was not a significant moderator for the association between goal interdependence in general and relationship satisfaction. A similar meta-analysis, which investigated goal support in relation to goal outcomes (not relationship satisfaction), also found that the effect size was not significantly different for general and specific goals (Vowels & Carnelley, 2020). This may be due to the highly heterogenous conceptualizations of goals even inside each of the two categories of the moderator (e.g., the specific-goal category includes goals that were health-related, relationship-related, professional etc.). This is also supported by the fact that, when investigated separately, goal type was actually a significant moderator for the association of goal support with relationship satisfaction since the grouping of studies based on the specific type of goal interdependence might have diminished the heterogeneity between them. Higher effect sizes were found for general goals, potentially because the studies focusing on general goals are more similar in how they measure goal support compared to studies focusing on specific goals.
For the remaining moderators, i.e., sample size, mean age, female percentage, and relationship length, which were also investigated exploratorily, we found no significant results. This is in agreement with other meta-analyses in the domain (Falconier et al., 2015; Vowels & Carnelley, 2020), as well as individual studies (Jakubiak & Feeney, 2016), that also found no significant effect for these moderators. This may be either due to the actual lack of a significant effect, the existence of other sources of heterogeneity that were not identified in the current meta-analysis, or due to the high heterogeneity between the studies included in the current meta-analysis.
Theoretical and practical implications
From a theoretical perspective, the results of the current meta-analysis provide support for the key assumption of the Transactive Goal Dynamics Theory, which posits that goal interdependence in couples is highly important for relationship functioning. However, since the theory only refers to goal interdependence as relevant to relationship persistence, the current meta-analysis extends this assumption by providing evidence that such interdependence is not only related to relationship strength, but also to relationship satisfaction. Our results also provide evidence for the evolutionary-informed goal systems theory (Orehek et al., 2018), which posits that people tend to feel closer and more committed to partners who are instrumental to their goals. Since feelings of closeness and commitment are deeply interrelated with satisfaction in relationships (Madey & Rodgers, 2009), satisfaction may also be influenced by partners’ instrumentality in people’s goal pursuit.
From a practical standpoint, our results support the importance of addressing goal interdependence in couples therapy and promoting congruence and appropriate support between partners. Based on our results, this seems to be equally relevant, irrespective of partners’ age, gender, and relationship duration. This is all the more important since studies show that incongruence between partners on goals related to children, work, division of household responsibilities, leisure time etc. Are highly common reasons for divorce (Hawkins et al., 2012) and negatively affect relationship satisfaction (Waddell et al., 2020). The matter of goal (in)congruence is likely to become even more conspicuous and a more common theme in couples therapy as the line between gender roles is slowly thinning and equal growth opportunities and responsibilities are promoted for both women and men.
Limitations and future directions
Despite the important contributions of our meta-analysis, it also has several limitations, which we detail below. Recommendations for future studies are also provided.
Firstly, we considered only three types of goal interdependence: goal support, goal congruence, and goal conflict. Importantly, as stated earlier, more nuanced conceptualizations are emerging, revealing more complex associations between goal interdependence and relationship satisfaction. For example, in recent studies, partner support has been divided into categories such as active versus passive (Fivecoat et al., 2015), emotional versus practical (Morelli et al., 2015), autonomy versus directive support (Jakubiak & Feeney, 2016), with different subcategories being differentially related to relationship outcomes. However, such conceptualizations are rarely used in studies on goal interdependence, making them currently suboptimal for meta-analytical investigations. More studies should, therefore, consider the effects of different types of goal-related support on relationship satisfaction. As the number of studies with more nuanced conceptualizations of support increases, future meta-analytic investigations should explore their overall associations with couples’ wellbeing.
Secondly, given the small number of samples in the goal congruence and goal conflict categories, moderator analyses could only be performed for the association between goal interdependence in general and relationship satisfaction and between goal support and relationship satisfaction. More studies on goal congruence and goal conflict are therefore needed to draw reliable conclusions regarding their associations with relationship satisfaction.
Thirdly, although some interesting patterns emerged when moderator analyses were performed, it is important to note that there was substantial residual heterogeneity for significant moderators, which could be due to different outcome measurements or different latent moderators that we could not analyze or identify due to the small number of studies.
The heterogeneity remained high even after including in the analysis the selected moderators, suggesting there might be others that explain the association between goal interdependence and relationship satisfaction. Variables such as personality characteristics, socioeconomic status, employment, disability, could also influence the investigated associations, however, we did not have enough data on them. Therefore, more studies should report such data to allow meta-analyses to assess their impact on the effect size of the association between goal interdependence and relationship satisfaction in couples.
Fourthly, although a relatively high number of studies included data from both partners, only a very small number reported actor and partner data on the association under investigation in the current meta-analysis. Future meta-analyses should therefore consider differences or similarities between actor and partner effects once more studies dyadic studies in the field of goal interdependence are published.
Lastly, despite our efforts two obtain more unpublished data to counteract publication bias, most of the data in the meta-analysis are published. As transparency in research increases and more unpublished data become accessible, future meta-analysis should include them in the analysis to provide a more reliable perspective on the association between goal interdependence and relationship satisfaction.
Conclusion
In conclusion, our meta-analysis provides robust evidence for the association between goal interdependence and relationship satisfaction in couples, as well as on the associations between different types of goal interdependence and relationship satisfaction. Goal support and goal congruence were positively related to relationship satisfaction, while goal conflict was negatively related to it. Our results provide evidence favoring the assumption that goal interdependence relates to romantic relationship functioning and support the importance of considering goal interdependence as an instrument for increasing relationship satisfaction in couples’ counseling.
