Abstract
Using structural equation modeling, we examined the relationship of Hispanicism on recent substance use and whether Americanism moderated the effect in a sample of 1,141 Hispanic adolescents. The Bicultural Involvement Questionnaire (BIQ) was used to determine the degree of individual comfort in both Hispanic (Hispanicism) and American (Americanism) cultures. Hispanicism was associated with greater family functioning (β = .36, p < .05) and school bonding (β = .31, p < .01); Americanism moderated the effect of Hispanicism on substance use (β = .92, p < .01). Findings suggest that Hispanic culture was protective against substance use; however, those effects differed depending on level of Americanism.
Introduction
An estimated 23.9 million Americans, or 9.2% of the population aged 12 years or older, report recent (i.e., past 30 days) illicit substance use (e.g., marijuana/hashish, cocaine, crack, heroin, hallucinogens, inhalants, and non-medical use of prescription medications); approximately 10% (2.4 million) were adolescent youth, 12 to 17 years. Among racial/ethnic groups reporting substance use, Hispanic adolescents report problematic use. Hispanic youth have the highest prevalences of lifetime, annual, and 30-day alcohol, cigarette, and licit and illicit drug use, excluding amphetamines, compared with their non-Hispanic White and Black/African American peers (Centers for Disease Control and Prevention [CDC], 2012; Johnston, O’Malley, Bachman, & Schulenberg, 2013; Substance Abuse and Mental Health Services Administration [SAMHSA], 2011). Hispanic youth are also more likely to initiate substance use at an earlier age compared with other ethnic minority youth (CDC, 2012).
Early substance use has been linked to a multitude of socio-behavioral and health difficulties including delinquency, poor school performance, higher proclivity for drug abuse and dependence (Benard, 2004; Bonnie & O’Connell, 2004; Miller, Naimi, Brewer, & Jones, 2007; SAMHSA, 2011), involvement with the criminal justice system, and engagement in sexually risky behaviors (CDC, 2011; Kotchick, Shaffer, Forehand, & Miller, 2001). These behaviors and social challenges may increase the risk of unplanned teen pregnancies and acquisition of sexually transmitted diseases (STDs), including HIV (Prado, Szapocznik, Maldonado-Molina, Schwartz, & Pantin, 2008). The aforementioned outcomes associated with substance use are adverse health conditions that disproportionately affect Hispanic youth, making the prevention of substance use and other adverse sequelae public health priorities.
Acculturation and Hispanic Substance Use
Some data suggest that identification with Hispanic cultural values (e.g., familismo, respeto) may protect youth from engaging in substance use and other risky behaviors (Castro et al., 2007). Acculturation to American culture, however, may weaken the potential protective effects (Lara, Gamboa, Kahramanian, Morales, & Hayes-Bautista, 2005; Lorenzo-Blanco, Unger, Ritt-Olson, Soto, & Baezconde-Garbanati, 2013) of Hispanic cultural values. For example, some studies have found acculturation to American culture to be associated with increased health and social risks (Berry, 2005; Turner, Lloyd, & Taylor, 2006; Van Wormer & Davis, 2013), greater substance use and dependence (de la Rosa, Holleran, Rugh, & MacMaster, 2005; Epstein, Botvin, & Diaz, 2001; Gil, Wagner, & Vega 2000; Martinez, Eddy, & DeGarmo, 2006; Rodriguez et al., 2007; Szapocznik, Prado, Burlew, Williams, & Santisteban, 2007; Warner et al., 2006), poor family functioning, lower school bonding, and associating with deviant peers among Hispanic adolescents (Prado et al., 2008). Conversely, some research has found endorsement of both American and Hispanic cultures to be protective for youth against substance use (Farelly, Cordova, Huang, Estrada, & Prado, 2013; Sullivan et al., 2007).
Studies examining the nuances related to the acculturation process are needed given the mixed findings in the literature. Given that acculturation is a multidimensional process that evolves throughout the life course (de la Rosa, Vega, & Radisch, 2000; Lopez-Class, Castro, & Ramirez, 2011), exploring the degree to which individuals identify with both their Hispanic culture and American cultural values and beliefs (Berry, 1997, 2007) may shed insight into how variations in acculturation affect critical socio-contextual predictors (e.g., family functioning, school bonding, and peer drug use attitudes and norms) of substance use as well as actual substance use (Berry, 1997, 2007; Valencia & Johnson, 2008).
Acculturation defined
The process of integrating and adjusting to a new culture involves changes in several life domains such as language and cultural preference (Lopez-Class et al., 2011). A prevailing issue is the degree to which one participates in the new culture (i.e., American) or the culture of origin, or vice versa (LaFromboise, Coleman, & Gerton, 1993). The level to which an individual participates in either culture can be stressful and difficult for families due to the conflict between Hispanic (i.e., emphasis placed on the family and community) and American cultural values (i.e., significance placed on the individual over the family; Prado et al., 2008). As a result, prior work has highlighted the complexity of acculturation with respect to Hispanic and American culture (Lopez-Class et al., 2011).
As such, investigating the complexity involved in the acculturation process is particularly salient when there is a juxtaposition between an individual’s struggle to preserve the culture of origin while participating in the newly adopted culture (Berry, 1997, 2007). In this vein, more research is needed that elucidates the influence of both cultures together on Hispanic family functioning (Smokowski, Rose, & Bacallao, 2008) and other ecodevelopmental predictors of substance use (e.g., school bonding, and peer drug use attitudes and norms). The consistent and significant associations with said ecodevelopmental factors alongside Hispanic youth substance use (Prado et al., 2008; Sullivan et al., 2007) highlight this need further.
Acculturation and Ecodevelopmental Predictors of Substance Use
Substance use occurs in developmentally predictable ways during adolescence (Martinez et al., 2006); assessing the mechanisms that contribute to Hispanic adolescent problem behavior requires an understanding of youth’s social and cultural contexts. Specifically, identifying how critical processes within youth’s family, school, and peer environments operate together to impact substance use and how they are influenced by acculturation may provide important insight for prevention efforts (Bacio et al., 2015). Ecodevelopmental theory, an ecological systems model, provides a multidimensional framework that helps explain the influence of family, school, peer, and acculturation mechanisms (Pantin, Schwartz, Sullivan, Coatsworth, & Szapocznik, 2003).
The micro-system, which is the focus of the current study, consists of the most proximal processes that influence adolescent development. These include the direct interactions youth have with parents, school, and peers, all of which have strong and direct influences on youth behavior (Pantin et al., 2003; Szapocznik & Coatsworth, 1999; Szapocznik et al., 2007). The family, specifically, contains highly influential proximal processes (e.g., parent-adolescent communication, positive parent-adolescent relationships, and parental support) among Hispanic families (Marsiglia, Kulis, Parsai, Villar, & Garcia, 2009; Prado et al., 2009) and is a critical social support system that contributes to the “development and well-being of its members” (Hepworth, Rooney, Dewberry Rooney, & Strom-Gottfried, 2013, p. 252). However, this support may be weakened during the process of acculturation (de la Rosa, & White, 2001; Gil et al., 2000; Martinez, Eddy, & DeGarmo, 2006; Prado et al., 2008; Schwartz, Zamboanga, Rodriguez, & Wang, 2007; Szapocznik et al., 2007; Turner et al., 2006). At the same time, some studies suggest that endorsement of both culture of origin and the new culture may have a positive impact on family functioning.
For instance, Farelly and colleagues (2013) examined the influence of adolescent acculturation on family functioning and found that youth endorsing both culture of origin and the new culture had greater family functioning and were less likely to engage in risky sexual behavior. Sullivan et al. (2007) found a similar relationship with youth endorsing both culture of origin and the new culture being significantly associated with higher family functioning and less behavior problems compared with other acculturating youth. From an ecodevelopmental perspective, the level to which youth retain their origin cultural practices and endorse the new culture may not only determine substance use risk and family functioning (Martinez et al., 2006; Schwartz et al., 2007) but also predict important relationships in the school and peer contexts such as school bonding and associating with deviant peers (Annuziata, Few, Hogue, & Liddle, 2006; Hawkins, Catalano, & Miller, 1992; Prado et al., 2010).
Research examining the interplay between family, school, and peer factors and their association with Hispanic adolescent substance use found that family functioning was indirectly related to substance use through school functioning and conduct problems (Lopez et al., 2009; Schwartz et al., 2009). Despite the finding that family functioning has a significant impact on school functioning and youth substance use, it is not well understood how school factors combine with acculturation, family, and peer mechanisms to influence substance use (Lopez-Class, Castro, & Ramirez, 2011). Assuming youth become more immersed into American culture through the school and peer contexts, acculturation may have a substantive impact on substance use through these particular processes (Bacio et al., 2015). The current study, therefore, fills a gap in the literature by examining the impact of acculturation on substance use, with the family, school, and peer contexts together in a mediational framework.
The complex associations between youth’s family, school, and peer systems can either aggravate or mitigate risky behavior, which highlights the critical importance of investigating these processes together (Szapocznik & Williams, 2000). For example, research has shown that youth who perform poorly in school are more likely to associate with substance-using peers (Swaim, Bates, & Chavez, 1998). Peers, in addition to the family and school environments, create critical ecodevelopmental settings in which youth experience risk as well as develop resiliency (Szapocznik & Coatsworth, 1999). Peers are considered to be one of the most influential proximal factors for youth during adolescence, and are necessary in understanding youth substance use (Koss-Chioino & Vargas, 1999). Furthermore, peers are a key acculturating mechanism for Hispanic youth (Pantin et al., 2003): As youth acculturate and gain more autonomy, they look to their peers for acceptance and may adopt American cultural practices in order to gain entry into peer groups. This developmental and cultural dynamic can increase youth susceptibility to antisocial peer pressure and subsequent problem behavior such as substance use (de la Rosa & White, 2001).
Youth micro interactions between parents, school, and peers are pivotal in shaping youth development in positive and negative ways; however, more studies are needed that examine the direct and indirect effects of acculturation on said ecodevelopmental factors. Moreover, the prevention of Hispanic youth substance use requires a contextualized framework that considers factors at the multiple levels in which adolescent development is embedded (Catalano & Hawkins, 1996; Szapocznik & Coatsworth, 1999). In light of the importance of Hispanic ecodevelopment, this study examines whether family functioning, school bonding, and negative peer drug use attitudes/norms mediate the relationship between acculturation and past 90-day substance use.
Current Study and Hypotheses
The relationship between Hispanicism (level of endorsement of Hispanic culture/culture of origin) and Americanism (level of endorsement of American culture/new or dominant culture) and socio-contextual predictors of substance use including family functioning, school bonding, and negative peer drug use attitudes/norms (see Figure 1) will be examined, allowing for a multilayered investigation of mediators of the relationship between acculturation and substance use (Pantin et al., 2003; Szapocznik & Coatsworth, 1999). Ecodevelopmental theory will be used as the guiding framework to test the direct and indirect effects of Hispanicism on family, school, and peer predictors of substance use as well as the effect of Americanism on Hispanicism and said ecodevelopmental outcomes (Pantin et al., 2003; Prado et al., 2010; Szapocznik & Coatsworth, 1999).

Conceptual model.
Three hypotheses were postulated:
Method
Data/Procedures
The current study combined baseline data from three randomized controlled trials (N = 1,148) of the Familias Unidas prevention intervention, which uses a parenting approach to reduce HIV and substance use risk behaviors among Hispanic youth (Prado et al., 2012). Two trials tested the efficacy of the Familias Unidas prevention intervention, and one trial tested the effectiveness of the Familias Unidas prevention intervention. Approval for this study was obtained from the University of Miami Social/Behavioral Sciences Institutional Review Board, the Miami-Dade County School Board’s research committee, and the U.S. CDC.
Participants in the first Familias Unidas trial consisted of 242 delinquent youth, 12 to 17 years of age (Prado et al., 2012). Hispanic adolescents and their parent/primary caregiver were recruited through the Miami-Dade Department of Juvenile Justice Services and the Miami-Dade County Public School system (Prado et al., 2012). In order to be eligible for this particular trial, youth had to have been arrested at least once or have a Level-3 behavior problem (e.g., assault, breaking and entering, fighting, possession of drugs or weapons, vandalism, etc.). Participants were randomized into one of two conditions: the Familias Unidas intervention or a community control condition (i.e., standard school prevention curriculum).
Data from the second trial used in the present study consisted of an efficacy study that tested a shortened version of the Familias Unidas intervention. The intervention was condensed from a 12-session program to a six-session program. Participants included 160 ninth grade Hispanic adolescents and their caregivers. Families were randomized to Familias Unidas or a community practice condition and were recruited from four high schools in Miami-Dade County. To be eligible for the study, participants had to be of Hispanic origin, attending ninth grade, living with a caregiver willing to participate, and living within the catchment area of the four targeted schools. Participants with prior psychiatric hospitalizations, or with plans to move out of the South Florida area during the study period, were excluded.
The third study was an effectiveness trial with 746 Hispanic, eighth grade adolescents and their adult primary caregiver. Participants were recruited from 18 randomly selected middle schools in Miami-Dade County that met the study’s inclusion/exclusion criteria. Schools located within the Miami-Dade County school district were the primary criterion at the school level. The criteria at the participant level included (a) female and male adolescents of Hispanic immigrant origin, (b) adolescents attending eighth grade at baseline, (c) adolescents living with an adult primary caregiver who was willing to participate; and (d) at baseline, families must have been living within the catchment areas of the participating middle schools.
The total sample (across all three studies) included 1,148 Hispanic youth, 627 (54.6%) males and 521 (45.4%) females, with a mean age of 14.24 years (SD = 0.86). The adolescent participation rate across all three studies was 65.76%. More than half (n = 656; 57.01%) of the adolescents were born in the United States; the remainder of adolescents involved in the study were immigrants born primarily in Cuba (37.4%), Colombia (10.8%), Honduras (7.5%), Nicaragua (6.9%), Argentina (5.7%), and the Dominican Republic (5.7%). The median household income ranged from US$15,000 to US$19,999.
Measures
Questionnaires across all trials were conducted on computers utilizing the Audio Computer Assisted Interviewer Program (A-CASI; Resnick et al., 1997). A-CASI has been shown to improve youth’s level of honest responses to questions with a sensitive nature (e.g., Metzger et al., 2000). Participants read or listened to items in the language of their choice.
Acculturation
The level of adolescent acculturation was measured using the Bicultural Involvement Questionnaire (BIQ), which assesses level of orientation to both American and Hispanic culture. The BIQ was designed specifically for Hispanics, and includes 11 items to assess Americanism and 11 items for Hispanicism (Zane & Mak, 2003). Five-point Likert-type scale items ranging from 1 = not at all comfortable to 5 = very comfortable measure comfort or enjoyment of both American and Hispanic cultures. Sample questions include “How much do you enjoy American music?” and “How comfortable do you feel speaking Spanish at school?” as well as ones that indicate desire to utilize the culture’s traditions and customs (e.g., celebrating birthdays the Hispanic way). Cronbach’s alphas for the Americanism and Hispanicism subscales were .88 and .91, respectively.
Family Functioning
A family functioning latent variable was constructed using five indices: positive parenting, parental involvement, parental monitoring, family communication, and parent-adolescent communication. Each scale was collapsed by summing the items and was treated as an indicator for family functioning. A confirmatory factor analysis (CFA) was then conducted to determine the feasibility of collapsing the five indicators onto a single latent family functioning construct.
Positive parenting (nine items, α = .78) and parental involvement (15 items, α = .87) were measured using the corresponding subscales from the Parenting Practices Scale (Gorman-Smith, Tolan, Zelli, & Huesmann, 1996). A sample item included, “When you have done something that your parents like or approve of” with response categories ranging from 0 = never to 3 = often.
Parental monitoring was measured using five items from the Parent Relationship With Peer Group Scale (α = .82; Pantin, 1996), which asks parents to indicate the extent to which they supervise their youth and how well they know their youth’s friends. A 5-point, Likert-type scale, ranging from 1 = not at all to 5 = extremely well (often), were the response options.
Family communication (three items, α = .74) was measured using a subscale from the Family Relations Scale (Tolan, Gorman-Smith, Huesmann, & Zelli, 1997). A sample item included, “How well do you personally know your child’s best friends?”
Parent-adolescent communication was assessed using 20 items (α = .90) from the Parent-Adolescent Communication Scale (Barnes & Olson, 1985). A sample question was “I can discuss my beliefs with my mother/father without feeling restrained or embarrassed” with response categories ranging from 1 = strongly disagree to 5 = strongly agree.
School Bonding
School bonding was assessed using seven items (α = .82) from the Psychological Sense of School Membership Scale (Goodenow, 2006). Only data from the School Bonding subscale, which measures perceptions of belongingness within a school setting, were used for the analysis. Sample questions included, “Most mornings I look forward to going to school” and “My school is a nice place to be.” Response categories ranged from 1 = not at all true to 3 = very true.
Peer Attitudes and Drug Norms
Peer attitudes and drug norms were assessed using three items (α = .83) taken from a subscale from the University of Southern California’s Health Behavior Survey (Pentz et al., 1989). Sample questions included, “If your friends found out that you drank sometimes, how do you think they’d feel?” and “If your friends found out that you smoked cigarettes or used chewing tobacco, snuff or dip, how do you think they’d feel?” Response categories ranged from 1 = they would approve to 4 = they would disapprove and stop being my friends.
Past 90-Day Substance Use
An overall, binary substance use variable was created using three indicators: past 90-day smoking, past 90-day alcohol use, and past 90-day drug use. Adolescent cigarette, alcohol, and drug use were measured using similar items utilized in the Monitoring the Future (MTF) study, a national epidemiologic study that assessed the prevalence of alcohol, cigarette, and illicit drug use (Johnston et al., 2013). However, the current study focused on past 90-day substance use whereas MTF Study assesses past 30-day use. As a result, a binary variable was created in the current study to demonstrate whether adolescents had smoked cigarettes, drank alcohol, or used an illicit drug in the past 90 days.
Data Analytic Plan
First, using Mplus (version 7; Muthén & Muthén, 2012), we estimated a measurement model using CFA to ascertain the feasibility of collapsing five indicators (i.e., positive parenting, parental involvement, parental monitoring, family communication, and parent-adolescent communication) onto a single latent family functioning construct. Each scale was collapsed by summing the items and was treated as an indicator for family functioning.
Second, we estimated the hypothesized structural equation model (see Figure 1). We used the default estimator, weighted least squares with mean and variance adjustment (WLSMV), in Mplus to estimate these models; WLSMV is suitable for dealing with categorical outcomes (Flora & Curran, 2004). Weighted least square parameter estimates were obtained by using a diagonal weight matrix, which is good in providing unbiased estimates (Muthén & Muthén, 2012), with standard errors and means. With WLSMV, a continuous latent response variable (y*) underlying the observed dichotomous variable was used.
To test the moderation effects of Americanism on the relationship between Hispanicism and past 90-day substance use, family functioning, school bonding, and negative peer drug use norms, we first created the interaction term by multiplying the Hispanicism and Americanism scores, and then regressed past 90-day substance use, family functioning, school bonding, and negative peer drug use norms on Hispanicism, Americanism, and the interaction term. The hypothesized indirect effects were tested using the asymmetric distribution of products test (MacKinnon, Lockwood, Hoffman, West, & Sheets, 2002); partial mediation is assumed if the confidence interval (CI) for this product does not include zero.
Model fit was examined using the comparative fit index (CFI), the root mean square error of approximation (RMSEA), and the chi-square (χ2) statistic. The CFI compares the hypothesized model with the null model while the RMSEA tests how well the hypothesized model fits the data (Byrne, 2012; Kline, 2011). The RMSEA estimates the deviation of the specified covariance matrix in the hypothesized model with the covariance matrix in the data. CFI values of 0.95 or greater (Bentler, 1990) and RMSEA values of 0.06 or less (Byrne, 2012; Steiger, 1990) indicate good model fit. Adolescent’s age, gender, nativity status (U.S. born or foreign born), household income, and cohort membership were controlled for in the model as covariates for outcomes.
Third, the standardized path coefficients were used to assess the size of the direct and indirect effects. Standardized path coefficients that assess the direct effect can be used as correlation coefficient (r) in structural equation modeling. As well, indirect and total effects can be calculated, with standardized estimates corresponding to effect-size estimates (Kline, 2011). As such, effect sizes were interpreted based on small (r = .10), medium (r = .24), and large effects (r = .37).
Results
Past 90-Day Substance Use
Three substance use indicators including past 90-day alcohol, smoking, and drug use were combined to create a binary past 90-day substance use variable. In order to provide context regarding problematic substance use among Hispanic youth, national statistics from MTF were utilized, specifically past 30-day use. It is important to note, however, that while MTF assesses past 30-day use, the current study examined past 90-day substance use. MTF substance use rates among eighth grade Hispanic youth were used given the average age of the current sample (14.24 years old). Past 90-day alcohol (11.8%) and cigarette smoking (6.5%) among Hispanic youth in the current sample were comparable with past 30-day national rates of use among Hispanics, which are 10% and 6%, respectively (Johnston, O’Malley, Dewberry Rooney, & Strom-Gottfried, 2014). Drug use among Hispanics was lower in this sample (8.4%) compared with MTF drug use (e.g., any illicit drug use: 17.8%).
Although substance use rates were comparable with national averages, it is important to note that a significant proportion of youth in the current study were foreign born (43%). Foreign born Hispanic youth tend to have lower rates of drug use than U.S. born youth, which this study also found (Almeida, Johnson, Matsumoto, & Godette, 2012; Bacio, Lau, & Mays, 2013; Borges et al., 2011; Pena et al., 2008; Prado et al., 2009). Past 90-day alcohol (14.7%), cigarette (7.5%), and drug use (10%) among U.S. born youth were higher compared with alcohol (7.9%), cigarette (5.1%), and drug use (6.3%) among foreign born youth in this sample.
Acculturation
Eleven, 5-point Likert-type items assessed Hispanicism and 11, 5-point Likert-type items assessed Americanism; the mean scores for Hispanicism and Americanism were 37.50 (SD = 10.73) and 48.07 (SD = 7.62), respectively.
Measurement Model
Family Functioning
Using CFA, all five family functioning subscales loaded significantly onto a single latent construct. The standardized factor loadings for parental involvement (p < .001), positive parenting (p < .001), parent-adolescent communication (p < .001), family communication (p < .001), and parental monitoring (p < .001) were 0.89, 0.74, 0.69, 0.60, and 0.53, respectively. The measurement model provided an adequate fit to the data, χ2(4) = 6.40, p = .17, CFI = 0.999, RMSEA = 0.023.
Structural Equation Model
The hypothesized structural equation model provided an adequate fit to the data, χ2(64) = 233.3, p < .001, CFI = 0.91, RMSEA = 0.048. We examined the interaction effects first and found there was a significant moderation effect of Americanism on the relationship between Hispanicism and past 90-day substance use (β = .85, p < .01). Thus, we conducted an analysis leaving out the three nonsignificant moderation effects; this model provided an adequate fit to the data, χ2(70) = 220.9, p < .001, CFI = 0.92, RMSEA = 0.044.
Direct Effects
The direct path from Hispanicism to family functioning (β = .36, p < .05) as well as the direct path from Hispanicism to school bonding were significant (β = .31, p < .01). The effect size from Hispanicism to family functioning was large while the effect from Hispanicism to school bonding was medium. Americanism significantly moderated the effect of Hispanicism on past 90-day substance use (β = .92, p < .01; see Figure 2). Specifically, the effect of Hispanicism on past 90-day substance use became positive with higher levels of Americanism (see Figure 3). The significant interaction between Hispanicism and Americanism on past 90-day substance use had a large effect.

Direct and indirect effects.

Plotted interaction effect.
Family functioning was positively associated with school bonding (β = .41, p < .001) and negative peer drug use attitudes/norms (β = .38, p < .001), which were large effects. Family functioning was also negatively associated with past 90-day substance use (β = −.17, p < .01). School bonding was inversely related to past 90-day substance use (β = −.17, p < .001) and positively related to negative peer drug use attitudes/norms (β = .18, p < .001). Negative peer drug use attitudes/norms was inversely associated with past 90-day substance use (β = −.20, p < .001). See Figure 2 for a visual depiction of the significant direct effects.
Indirect Effects
There was a statistically significant indirect effect between Hispanicism and past 90-day substance use through school bonding and negative peer drug use attitudes and norms (β = −.01, p < .05, 90% CI = [−0.022, 0] 1 ); as well, there was a significant indirect effect between Hispanicism and past 90-day substance use through school bonding (β = −.05, p < .05, 90% CI = [−0.102, 0]; see Footnote 1).
Interaction Effect
As mentioned previously, there was a significant interaction effect between Hispanicism and Americanism on past 90-day substance use (Figure 3). The Americanism and Hispanicism interaction was continuous. The results of the interaction indicated that the inverse effect from Hispanicism to past 90-day substance use changed to a positive effect as the level of Americanism increased. Specifically, Hispanicism was associated with higher past 90-day substance use as Americanism increased.
Post Hoc Analyses
Sample Comparisons
As multiple youth samples were combined for the current study, we conducted multigroup analyses with the adjudicated and non-adjudicated samples to test for possible differences between samples. First, to test for measurement invariance, a multigroup CFA was conducted on the family functioning measurement model comparing the samples. The results supported configural invariance, χ2(8) = 7.311, p = .5, RMSEA < 0.001, CFI = 0.999, as well as metric invariance: constrained factor loadings, Δχ2(4) = 6.72, p = .15, RMSEA = 0.017, CFI = 0.999. However, scalar invariance (constraining indicator intercepts) was not supported: Δχ2(4) = 33.042, p < .001. Due to these results, we proceeded with metric invariance. Second, we compared the model with all paths freely estimated and the model with all paths (except the paths from covariates) constrained. Results indicated that constraining these paths did not significantly worsen model fit: Δχ2(18) = 27.93, p = .063. Both the constrained, χ2(126) = 240.94, p < .001, RMSEA = 0.04, CFI = 0.931, and freely estimated model, χ2(108) = 235.58, p < .001, RMSEA = 0.046, CFI = 0.924, demonstrated good fit. Thus, the results showed that there were no differences between these samples.
Discussion
This study examined the direct and indirect effects of acculturation to American culture and retention of culture of origin on substance use through the ecodevelopmental mechanisms of family functioning, school bonding, and negative peer drug use attitudes/norms. Cultural processes, such as acculturation, are central in understanding the etiology of substance use (Alegria, Vallas, & Pumariega, 2010). As well, acculturation is a fundamental process to investigate among Hispanics, considering they are the fastest growing minority group in the nation and given the make-up of the current sample (i.e., many participants were first and second generation immigrants). Due to the negative public health and social ramifications of youth substance use and subsequent HIV risk, understanding the ecodevelopmental mechanisms through which acculturation processes affect substance use may provide critical insight into the nuanced way that acculturation influences youth development. This study fills a current gap in the literature by using mediation analyses to examine the effects of retention of culture of origin and acculturation to American culture on important Hispanic adolescent ecodevelopmental contexts and substance use. This study found Hispanicism (i.e., youth endorsing Hispanic cultural values and beliefs) to be associated with lower substance use; however, those effects decreased for youth exhibiting higher levels of Americanism (i.e., oriented to American culture).
It was first hypothesized that higher levels of Hispanicism would be associated with greater family functioning, school bonding, negative peer drug use attitudes and norms, and lower past 90-day substance use. Results indicated that greater Hispanicism was significantly associated with greater family functioning, school bonding, and lower past 90-day substance use. Secondly, it was hypothesized that family functioning, school bonding, and negative peer drug use attitudes/norms would mediate the effects of Hispanicism on substance use and was partially supported; school bonding and peer drug use attitudes and norms mediated the effects of Hispanicism on substance use. The significant direct and indirect effects of Hispanicism on these ecodevelopmental outcomes and substance use are in accordance with previous research (Annuziata et al., 2006; Hawkins et al., 1992; Prado et al., 2010).
Despite some research finding retention of culture of origin to be associated with increased substance use (Fosados et al., 2007), the present finding that Hispanicism was associated with lower substance use is consistent with other studies that have found retention of culture of origin to be protective for Hispanic youth (Berry, 2007; Nguyen & Benet-Martinez, 2013; Rosiers, Schwartz, Zamboanga, Ham, & Huang, 2013; Schwartz, Unger, Zamboanga, & Szapocznik, 2010; Smokowski et al., 2008). As well, this study found that family functioning, school bonding, and negative peer drug use attitudes/norms were mechanisms through which Hispanicism operated in a protective manner. Hispanic cultural values and norms may contribute to decreased antisocial behavior such as substance use (Gamst et al., 2002), specifically as a result of Hispanic culture being more restrictive compared with American culture regarding individual freedom (Castro et al., 2007). Youth who endorse Hispanic culture may be more apt to adhere to Hispanic social norms that stress the importance of family, a critical protective factor, over the individual and may protect youth from substance use. Parents in Hispanic families tend to keep their culture of origin norms, which may mitigate intergenerational conflict with their children (Dinh, Roosa, Tein, & Lopez, 2002). In due course, positive family functioning may provide social support and encouragement to do well in school. The social support of the family may allow youth to have an easier time acclimating to the American school system and may result in a positive bonding experience with their school. This may decrease the likelihood of youth associating with deviant peers and increasing their chances of not using substances.
The result of the continuous interaction between Hispanicism and Americanism indicated that the protective effects of Hispanicism decreased for youth as Americanism increased. Although some research has found acculturation to American culture to be protective against substance use and psychosocial problems (Rosiers et al., 2013; Schwartz et al., 2007; Smokowski et al., 2008), other studies have found it to be a risk factor for substance use (Epstein, Botvin, Dusenbery, Diaz, & Kerner, 1996; Portes & Rumbaut, 1996; Sullivan et al., 2007; Vega & Gil, 2002). In this study, it was hypothesized that Americanism would moderate the effect of Hispanicism on family functioning, school bonding, peer drug use attitudes/norms, and past 90-day substance use. This hypothesis was partially supported as Americanism moderated the effect of Hispanicism on past 90-day substance use, which supports evidence surrounding the risk effects of acculturation to American culture and the protective effects of Hispanicism. These findings suggest that substance use risk as a matter of acculturation to American culture depends on the degree to which youth are acculturated, demonstrating the varied effects of acculturation on substance use for youth. Youth who highly endorse American cultural interests and values may result in deterioration in Hispanic family norms, values, and attitudes regarding substance use, thereby increasing risk for deleterious risk behavior (Szapocznik et al., 2007).
Lastly, no significant moderation effects were found between Americanism and the hypothesized mediators. Given the high value that Hispanics place on the family, the level of Americanism may not influence levels of family functioning as long as a high level of Hispanicism is present. This falls in line with previous research that states that what is important for youth health outcomes is retaining Hispanic values, not necessarily gaining or losing American values (Schwartz et al., 2012; Schwartz et al., 2015). Specific to school bonding, the lack of an interaction effect may suggest that school bonding is protective regardless of level of Americanism as the protective processes offered by retention of Hispanic cultural values often translate into strong school ties. Regarding the peer context, the lack of a significant moderating effect may have resulted from the small and nonsignificant association between Hispanicism and negative peer drug use attitudes/norms. Although youth’s familial and school relationships have a larger influence on youth during early adolescence, the effect of Americanism on Hispanicism and peer drug use attitudes may become more pronounced as youth age, gain autonomy, and increasingly look toward their peer group for acceptance. Overall, these results demonstrate the complex relationships between acculturation, ecodevelopment, and substance use.
Findings from this study indicate a need for exploring the effects of Hispanicism and Americanism in more depth, given the decreased effect of Hispanicism on substance use for youth who scored high on the Americanism measure. Although the capacity to think and behave consistently within both cultural contexts is thought to counteract the negative effects of acculturation on substance use as well as ecodevelopmental outcomes, findings from this study suggest that acculturation specific to culture of origin and American culture is a more complex and detailed process. Thus, future studies should assess Hispanicism and Americanism more closely and examine whether the direction of effects for both acculturation continuums change depending on where youth are in the acculturation process with respect to both cultures. Examining the interplay between both continuums in more depth may elucidate specific points of intervention for acculturating youth and provide further understanding to how Hispanicism and Americanism operate for adolescent youth navigating both cultures.
Findings from this study were in accordance with previous research that supported associations between positive family functioning, school bonding, associating with prosocial peers, and lower substance use (Annuziata et al., 2006; Hawkins et al., 1992; Prado et al., 2010); however, more research is needed that explores the effects of acculturation on these outcomes longitudinally. Although this study did not find any significant interaction effects between Hispanicism and Americanism on ecodevelopmental outcomes for youth in this sample, results indicated that school bonding and negative peer drug use attitudes/norms were mechanisms in which Hispanicism operated in a protective manner. As youth who have poor family functioning or perform badly in school are at increased risk for associating with deviant peers and substance use (Prado et al., 2008; Swaim et al., 1998), illuminating the level at which endorsing Hispanic culture and American culture provides youth with support that is conducive to positive ecodevelopment and lower substance use is critical. Furthermore, adolescent youth experience many changes during this important developmental period, and peers are an important mechanism that may expose acculturating youth to pro-substance use norms (Fosados et al., 2007; Pantin et al., 2003). Both the family and school contexts, therefore, may contain critical processes that promote positive functioning and prosocial behavior.
To this team’s knowledge, this is the first study that examined the impact of acculturation, specifically, the endorsement of Hispanic and American culture, on substance use, with the family, school, and peer contexts together in a mediational framework. Although some significant medium and large effects were found, other significant paths had small effects and should be interpreted with caution. Although Hispanicism was protective for Hispanic youth, studies are needed that further explore the intricacies associated with Hispanicism and Americanism together as they influence youth ecodevelopment and substance use over time.
Limitations
There were several limitations to the current study. First, due to the cross-sectional nature of the study design, causal relationships cannot be determined. Second, given the unique nature of the South Florida area, generalizations to other Hispanic subgroups located outside of the region should be made with caution. For example, as a group, Latinos/Hispanics in South Florida may have more economic and/or political power, which may differentially impact acculturation effects. Studies with Hispanic populations in other regions of the United States would need to be conducted to determine if our findings can be replicated. Third, given the differences in use among youth for each substance, the interplay between acculturation and ecodevelopmental outcomes may vary. In addition, due to varying social acceptance of alcohol use versus illicit drug use, acculturation and ecodevelopmental outcomes may differ on these particular substance use outcomes as a result. Furthermore, dichotomizing substance use may not allow researchers to detect the true magnitude of an effect compared with leaving substance use as a continuous outcome. Fourth, effect sizes should be interpreted with caution as many of the significant direct and indirect effects were small. Finally, self-report measures were employed across all three studies, which could potentially bias participant responses. There is the possibility that participants may not provide an honest response, particularly for questions that may cause anxiety or embarrassment; however, this is mitigated by our use of the A-CASI system.
Conclusion
This study provides insight into the impact of acculturation and ecodevelopmental factors on Hispanic adolescent substance use. Findings from this study indicated that Hispanicism was associated with greater family functioning and was protective against substance use through school bonding and peer drug use attitudes and norms. As well, the effect of Hispanicism on substance use was moderated by Americanism. This finding, relating specifically the level at which Americanism becomes risky for youth, needs more exploration given the mixed research regarding acculturation to American culture. Studies that elucidate the varied effects and nuances of acculturation can provide insight into how endorsement of one’s own culture interacts with the effects of adhering to American cultural norms on risky behavior and can help in the tailoring of prevention/intervention programming targeting Hispanic youth. Given the projected increase in the Hispanic population over the next few decades, understanding the risk and protective effects of acculturation and ecodevelopmental factors on adolescent substance use may help clinicians work more effectively with Hispanic immigrant populations. Clinicians who are aware of the subtleties surrounding acculturation processes specific to Hispanic and American cultures and their associated health risk behaviors may be better able to tap into key protective processes that mitigate these behaviors.
