Abstract
Introduction
The chronic effects of ADHD and its repercussions on the family are aspects that are of great importance to assess due to their implications on family relationships throughout the life cycle. As described by Agha, Zammit, Thapar, and Langley (2013), the parental problems of children diagnosed with ADHD are associated with severe clinical symptoms and greater family adversity. Schei, Jozefiak, Stene Novik, Lydersen, and Indredavik (2016) studied the impact of coexisting emotional and conduct problems on family functioning and quality of life among adolescents with ADHD; their results showed that the participants diagnosed with ADHD reported lower quality of life and family functioning. The purpose of this study is to explore family functioning variables during childhood in adults diagnosed with ADHD.
According to Modesto-Lowe, Danforth, and Brooks (2008), regarding the relationship between ADHD and parent variables, education styles are one of the most important areas. McKee, Harvey, Danforth, Ulaszek, and Friedman (2004) observed that in families with one child with ADHD, the parents tend to exercise greater control and criticism; they react excessively to impulsive conduct, use reprimands and punishments with greater frequency, and value their children less than in the control groups. At the same time, they are less affectionate, feel less confidence in their ability to bring up children, and have greater levels of distress. In the same way, the studies of Raya, Herreruzo, and Pino (2008) in children and of Buschgens et al. (2010) among preadolescents showed that authoritarian and permissive education brings about hyperactive and exaggerated conduct. Foley (2010) observed that families with children diagnosed with ADHD show greater levels of family dysfunction than those with children who have not been diagnosed with ADHD. Moreover, Weiss and Hechtman (1993) reported than an emotional and/or hostile climate in the home is a bad predictor of ADHD at adult age. These studies indicate greater severity of ADHD when there are disagreements between parents and siblings; in such cases, it is more difficult for children with ADHD to hide their impulses and obey orders, provoking behavior problems that are difficult to manage. The parents are more coercive and inconsistent with their children, causing the feeling of lack of competence as parents. This frustration has repercussions on the child and brings about negative results that influence the symptoms of the disorder and cause disagreeable family situations (Grau-Sevilla, 2007).
According to Linares (1996), the family is one of the most significant contexts in the development of a child. It plays a crucial part in the process of bringing up a child, during which the parents provide the nutritive relationship that is absolutely necessary for the child’s maturity as a person.
To the best of our knowledge, no studies have focused on family functioning, parental bonding, and the relationship between the two in adults diagnosed with ADHD. In this sense, the systemic theory offers a theoretical framework appropriate for such study because it does not center on the cause of the dysfunctions but focuses on the interaction between family variables and the expression of the disorder, as well as on their circular causality. This also has clinical implications: When considering relational and bidirectional variables in the study of ADHD, the treatment possibilities increase. Although the notion that parents have an enduring influence on their children has intuitive appeal, the behavior and temperament of the child can also affect the quality of parenting (Cunningham, 2007).
The Olson Circumplex Model (Olson, Russell, & Sprenkle, 1983) is widely used in systemic studies to evaluate family behavior but not in relation to psychopathology. It comprises three key concepts. The first is cohesion, defined as an emotional bond (degree of separation or connection) that family members have among themselves. The second is adaptability, expressed as the ability of the family or conjugal system to adapt its power structure, its roles, and the norms of the relationship in response to stress caused by a concrete situation or by the vital development of the whole family. The third concept, communication, refers to positive communicative abilities used in the family (Olson & Gorall, 2003).
This model facilitates the identification of 16 types of conjugal and family systems distributed into three groups: balanced, extremes, and intermediate. The communication dimension exercises a facility function on family behavior. The other two dimensions are curved lines, which means that the extremes are dysfunctional (little or excessive cohesion and/or adaptability). The Circumplex Model is dynamic and presumes that persons and families will change. It formulates the hypothesis that change can favor the maintenance or improvement of family behavior and leave room for change within reasonable limits (Lopez Larrosa, 2002).
Parental bonding, understood as the significant dyadic and stable relationship between children and their parents, is an important environmental factor to consider in the study of ADHD across the life span. The model developed by Parker, Tupling, and Brown (1979) classified such bond into four types based on the dimensions of care and overprotection. The care dimension refers to emotional warmth, concern for the welfare of the child, and positive acceptance/appreciation of the same. However, the overprotection dimension refers to control, intrusion, excessive contact, and prevention of independent behavior of the child. The optimal parenting offers acceptance and appreciation, guides affection and care, and promotes child autonomy. An affectionate constraint bond comes from an ambience of controlled warmth and acceptance, but it does not foster either autonomy or growth. An affectionless control bond is intrusive, based on norms and forced autonomy. Finally, neglectful parenting comes about when the child receives neither affection nor recognition, nor are his needs for protection taken into account.
Following this model, numerous previous investigations have associated a dysfunctional bond with the expression of schizophrenia (Willinger, Heiden, Meszaros, Formann, & Aschauer, 2002), mood disorders (T. Narita et al., 2000), obsessive and compulsive disorder (Wilcox et al., 2008), and general psychopathology (Heider, Matschinger, Bernert, Alonso, & Angermeyer, 2006; Klensmeden Fosse & Holen, 2002; K. Narita et al., 2010; Parker, 1983). High levels of care dimension in both parents diminish the probability of provoking mood disorders (Heider et al., 2006). A style of education based on control without affection has also been associated with externalizing problems (Iglesias & Romero, 2009). Vilaregut (2003) used these two models to study the connection between drug use, family functioning, and parental bonding, concluding that the families of patients with drug abuse disorders show low adaptability, extreme cohesion, and an affectionless control bond. Gau and Chang (2013) found that ADHD adolescents reported less affection or care and more overprotection and control from their mothers and perceived less family support.
The aim of the present study is to explore and analyze family functioning, parental bonding, and the relationship between the two during the childhood of ADHD adults. The revision carried out leads us to propose the following hypothesis. On one hand, families with a member diagnosed with ADHD would be situated in the two extremes of the adaptability dimension (rigid or chaotic) and of cohesion (enmeshed or disengaged) regarding family functioning. On the other hand, they would show a greater prevalence of parental bonding based on affectionless control. However, control group would present flexible or structured adaptability and separated or connected cohesion in family functioning. In parental bonding, they would show an optimal parenting. In addition, we expect no significant differences between groups in relation to age, gender, or socioeconomic status.
Method
Design
This study used an ex post facto, retrospective design with two groups: an experimental group and a quasi-experimental control group.
Participants
The participants consisted of 100 adults, 50 for the experimental group and the other 50 for the control group. All of them signed a consent form indicating their agreement to participate in the study. The study was approved by the ethics committee of Hospital Universitari Vall d’Hebron (Barcelona, Spain). The selection of participants was based on an intentional and nonprobabilistic sample. The experimental group consisted of male (65.9%) and female (34.1%) patients, ages between 18 and 47 years (M = 31.69, SD = 9.20), who attended the adult ADHD program of the Department of Psychiatry of Hospital Universitari Vall d’Hebron. Diagnosis of ADHD was established by experienced senior psychiatrist using semi-estructured interviews .The Spanish version of the Conners Adult ADHD Diagnostic Interview for DSM-IV was used. (CAADID, where DSM-IV represents Diagnostic and Statistical Manual of Mental Disorders [4th ed.]; American Psychiatric Association, 1994). The presence of comorbid disorders was evaluated with the Structured Clinical Interview for DSM-IV Axis I(SCID-I) and Structured Clinical Interview for DSM-IV Axis II(SCID-II) . Participants who showed oral and/or written comprehension difficulties in Catalan or Spanish were excluded, as were those with an IQ below 80 and/or comorbidity with other mental disorders, such as substance use disorders, mood disorders, anxiety disorders, or personality disorders.
The control group consisted of participants with similar sociodemographic characteristics to the experimental group. In this group, the sample was equally distributed between males and females, and the mean age was 30.76 years (SD = 10.73). The inclusion criterion for this group was absence of ADHD diagnosis or other mental disorders among the participants or their family members. After the data collection, six participants were excluded from the experimental group due to comorbidity with other psychiatric disorders. We also excluded six participants from the control group, choosing to retain only those who shared the same sociodemographic characteristics to preserve the homogeneity of the sample. We decided to exclude comorbidity (either in patients or in relatives) because previous studies have proven that oppositional defiant disorder, conduct disorder in children with ADHD, and psychiatric disorders in parents correlate with greater family dysfunction (Modesto-Lowe et al., 2008). All the participants included in the experimental group (ADHD) were diagnosed with ADHD for the first time at adulthood. The definitive sample consisted of 88 participants of Spanish nationality.
Instruments
All participants completed a questionnaire, including items on sociodemographic data, and the following instruments.
Family Adaptability and Cohesion Evaluation Scale short Spanish version (FACES-20esp)
This is a short, 20-item version of the American FACES II (Family Adaptability and Cohesion Evaluation Scale) (Olson, Portner, & Bell, 1982), culturally adapted to Spain by Martínez-Pampliega, Iraurgi, Galindez, and Sanz (2006). The instrument measures family functioning from the perspective of children, and it is based on cohesion and adaptability dimensions (following the Olson model). The 10-item cohesion scale assesses emotional ties and internal and external borders (in relation to space, time, decision making, interests, and leisure time).
The 10-item adaptability scale refers to assertiveness, leadership, control, discipline, and negotiation concepts. All items are rated on a 5-point Likert-type scale. The reliabilities of both theoretical dimensions are good (Cronbach’s alpha of .89 for the cohesion score and of .87 for the adaptability score), with a test–retest reliability of .83 for cohesion and .80 for adaptability. The construct validity is endorsed through factor analysis (goodness-of-fit index [GFI] = .92, normed fit index [NFI] = .89, root mean square error of approximation [RMSEA] = .07), according to Martínez-Pampliega et al. (2006).
Parental Bonding Instrument (PBI)–Orthodox version
This was designed by Parker et al. (1979), but we used the Spanish-adapted version by Ballús Creus (1991). The instrument is a self-report device that assesses an individual’s perception of parental bonding experiences, based on his or her memories up to 16 years old. The instrument considers two significant dimensions: care and overprotection. It consists of 25 items (13 in the Overprotection subscale and 12 in the Care subscale), rated on a scale ranging from 0 to 3 (strongly agree, moderately agree, moderately disagree, and disagree). Each scale is duplicated to find the perception of bonding with father and with mother, respectively. The reliabilities of these two dimension scales are Care α = .76 for mothers and α = .82 for fathers, and Overprotection α = .70 for mothers and α = .72 for fathers, according to Sánchez-Queija and Oliva (2003). The score intersection in each dimension allows the determination of the type of parental bonding. The test–retest reliability is high, even for long periods of more than 10 years (Parker, 1990).
Statistical Analysis
Descriptive analysis was used for the sociodemographic data and ADHD diagnosis. The means, standard deviations, and Student’s t test were used to compare the experimental and control group scores on the FACES-20esp and PBI.
Given that parental bonding and family functioning typologies are categorical variables, we applied the chi-square test to find significant differences between the ADHD and control groups.
We used Pearson’s correlation to evaluate the correlations between the cohesion/adaptability variables of the FACES-20esp and the care/overprotection variables of the PBI. Finally, to determine whether age, gender, socioeconomic status, and educational level were related to family functioning and parental bonding in the ADHD and control groups, Pearson correlations were used.
The independent variables were group (ADHD vs. control), age, gender, socioeconomic status, and academic level. The significance level used was .05, two-tailed. The SPSS software (Version 19.0) was used to analyze all the data.
Results
Family Functioning
Family functioning was assessed by using the FACES-20esp. The scores on the adaptability and cohesion scales were significantly lower in ADHD participants than in controls (see Table 1). Family functioning is the result of combining the subscale scores of Cohesion and Adaptability. As shown in Figure 1, the major percentage of the ADHD group was classified under the rigid-disengaged family functioning type (31.8%), whereas the participants without ADHD were distributed into two family types: chaotic-enmeshed (22.7%) and flex-connected (20.5%).

Parental Bonding
Parental bonding was assessed by using the orthodox PBI. We found that parental care scores were significantly lower in the ADHD group. The scores for maternal care resulted in M = 24.7 ± 8.01 versus M = 28.73 ± 6.05 (t = −2.657, p < .05). The scores for paternal care were M = 19.22 ± 8.42 versus M = 24.86 ± 6.05 (t = −3.567, p < .05). The two groups did not differ significantly in parental overprotection.
Figure 2 shows the parental bonding types obtained by combining the care and overprotection scores. The ADHD group mostly remembered a dysfunctional bond with mother and father, defined as affectionless control. The group without ADHD recalled an optimal bond with mother and father.

Four types of parental bonding in the experimental and control groups.
The results shown in Table 2 reveal a positive association between family functioning and parental care and negative correlations between family functioning and parental overprotection. Significant correlations were found between family cohesion and parental care (r = .605 with the mothers and r = .540 with the fathers) and between family adaptability and parental care (r = .602 with the mothers and r = .569 with the fathers). Family cohesion was negatively correlated with parental overprotection (r = −.101 with the mothers and r = −.155 with the fathers). Family adaptability was also negatively correlated with parental overprotection (r = −.071 with the mothers and r = −.185 with the fathers).

The influence of the demographic variables on parental care and family functioning was also analyzed. Paternal care in the ADHD group was found to be higher in lower socioeconomic levels (R = .443). Maternal care in the ADHD group was directly and significantly related to age (R = .342). Also, significant gender differences were found, with females associated with higher family cohesion (R = .343).
Discussion
Following the Circumplex Model of family functioning proposed by Olson et al. (1983), significant differences were found between the experimental and control groups. A high percentage of participants with ADHD remember their families as rigid-disengaged. Consistent with our hypothesis, this corresponds to an extreme, and therefore dysfunctional, family type.
Regarding adaptability, a high percentage of participants with ADHD reported rigidity, recalling difficulties in their families in negotiating rules, patterns, and leadership throughout the life cycle and in response to stressful events. Regarding cohesion, most of the participants with ADHD reported little or poor emotional connection between family members and little sharing among them.
These data support our hypothesis that most families with a member diagnosed with ADHD are dysfunctional types. Controller, repetitive, and forceful parenting styles in response to impulsive behavior, as observed by McKee et al. (2004), are consistent with a dysfunctional and rigid adaptability to stressful situations. The impulsivity and hyperactive behavior are strongly controlled with rigid and strict rules. Little changes are introduced during childhood and youth. Negative feedback patterns in interactions between parents and children with ADHD (Grau-Sevilla, 2007) and a lower quality of affection and communication (Foley, 2010) may increase the feelings of emotional distance in this kind of family. Less family cohesion may hinder the planning of leisure time, provoking less interest in doing activities together and difficulties in decision making.
We observed that the control group was divided into two types of family functioning. The first type, the chaotic-enmeshed extreme, obtained a representative percentage. This kind of family style tends toward excessive proximity between members, with defined limits to outside relationships, as noted in Spanish families by Lopez Larrosa (2002). High scores on adaptability, in turn, are related to lack of control, lax discipline, and excessive negotiation and permissiveness between parents and children. The second type is the flexible-connected group, which is concerned about the needs of its members, enhances the expression of different opinions, negotiations, and problem solving, and promotes the perception of fair discipline.
Following the PBI developed by Parker et al. (1979), we found that young adults with ADHD have significantly lower scores in the care dimension and showed an affectionless control bond (the intersection of lack of care and overprotection). Their parents tend to be indifferent, rejecting, and lacking in emotional warmth.
The parenting dimensions obtained by the PBI showed that parental behavior and attitudes in the ADHD group had significantly more control, less warmth, and more disapproval, as McKee et al. (2004) observed. Also, Raya et al. (2008) and Buschgens et al. (2010) related an authoritarian education style (more criticism, colder approach, and strict rules) with externalizing behavior. The parental style of low care/high overprotection (affectionless control) reported by this group is associated with problems in multiple adaptive functioning areas, such as school and social relationships. These findings are related to the theory of emotional nurture for the healthy development of a child described by Linares (1996). We observed that in families with ADHD members, weak emotional ties and rigidity are associated with low care and overprotection, increasing the probability of developing problematic profiles (low values of identity and self-esteem, self-control problems, and bad relationships with peers, such as personal and social conflicts). This generates new difficulties in the family functioning, perpetuating a cycle of negative feedbacks (Grau-Sevilla, 2007). The influence of a family style characterized by little capacity to adapt to changes, excessive discipline and control, and rigid, hardly negotiable relational rules contributes to a set of poor family relationships (rigidly unrelated families).
The findings of our study make it clear that we cannot ignore family relationships in ADHD research. There must be a joint effort to promote comprehensive intervention at all levels, as proposed by Alegret (2007), whereas the multimodal treatment, pharmacological intervention, and psychoeducation should be complemented by family therapy. Family therapy in patients with ADHD should aim to improve communication, promote the adjustment of parents regarding changes in behavior, and facilitate emotional connection between family members.
One limitation of this study is that we analyzed only the information reported by patients through the FACES-20esp and the dimensions proposed by the Circumplex Model. Comparative scales are necessary for family functioning analysis in relation to the presence of symptoms associated with pathology. Another limitation is the dilution of the sample, which was distributed into 16 family types. In subsequent studies, a larger sample should be considered. Besides, the FACES-20esp and PBI are retrospective self-report measures, which can result in biased memories. For this kind of study, a longitudinal design would be optimal so as to gather responses referring to the present time. Finally, the results of this study cannot be extrapolated to adults with ADHD in the general population because the ADHD sample was selected from a specialized university hospital program.
Conclusion
The results show that participants with ADHD obtained a high score on dysfunctional family functioning with a rigid, separated typology. The parental bonding results show that most participants with ADHD obtained a low score on the care dimension and remember a maternal bond based on control without affection. Regarding their relationship with their parents, the highest recall indicated a bond based on control without affection.
The obtained results support the evidence regarding the influence and impact of family relationships on each of the family members, regardless of the existence of mental illness. We believe it is necessary to continue investigating family variables in the field of ADHD and to develop comprehensive programs that include family intervention to ensure optimal treatment and better prognosis in families with a member with ADHD.
