Exploring Parental Influence on the Progression of Alcohol Use in Mexican-Heritage Youth: a Latent Transition Analysis.

Mexican-heritage youth are members of the fastest growing minority group and are at particular risk for substance use including alcohol consumption. Youth face numerous risk factors including positive descriptions of substance use on media and peer offers that are potentially ameliorated by parental anti-substance use socialization efforts. Guided by primary socialization theory and the theory of planned behavior, the present study posited eight research questions to identify discrete subgroups/patterns of Mexican-heritage youth alcohol use behavior and parental influence on youth outcomes. Longitudinal survey data (n = 1147) from youth in 29 public schools located in Phoenix, Arizona, were collected over 3 years. Latent class and transition analyses identified four discrete subgroups characterized by response patterns of alcohol use behaviors and perceptions in Mexican-heritage youth: (1) non-drinker, (2) potential drinker, (3) experimenter, and (4) regular drinker. Targeted parent-child communication about alcohol and parental monitoring were found to be significant predictors for youth alcohol use. Research implications and future directions are suggested.

Does parentification place Mexican-heritage youth at risk for substance use? Identifying the intervening nature of parent-child communication about alcohol.

Past research on parentification suggests that adopting adult responsibilities to the point at which the child plays a parental role places children at risk for poor mental and behavioral health outcomes. Since family relations are particularly important in Mexican culture, two hypotheses were posed to examine the indirect effects of parentification on Mexican-heritage youths' substance use via parent-child communication about alcohol, while examining the moderating effects of parent-child closeness. Mexican-heritage youth (N = 697) from 23 public middle schools in Phoenix, AZ completed surveys at three waves. Structural equation modeling results provided partial support for the hypotheses. Mexican-heritage youth experiencing problem-solving parentification were more likely to talk with a parent about alcohol and, in turn, less likely to use substances. This mediation effect, however, was not found with respect to adult parentification, and parent-child closeness was not a significant moderator. Implications for the beneficial effects of problem-solving parentification are discussed.

Ethnic Identity Development and Acculturation: A Longitudinal Analysis of Mexican-Heritage Youth in the Southwest United States.

Utilizing part of the survey data collected for a National Institute on Drug Abuse (NIDA)-funded project from 29 public elementary schools in Phoenix, Arizona (N = 1,600), this study explored the underlying structure of Mexican-heritage youths' ethnic identity and cultural/linguistic orientation. Latent profile and transition analyses identified four distinct orientation profiles endorsed by the early adolescents and their developmental trends across four time points. Most Mexican and Mexican American adolescents endorsed bicultural profiles with developmental trends characterized by widespread stasis and transitions toward greater ethnic identity exploration. Multinominal logistic regression analyses revealed associations between profile endorsement and adolescents' gender, socioeconomic status, parents' birthplace, and visits outside the United States. These findings are discussed in regard to previous findings on acculturation and ethnic identity development. Individuals' adaptation to the immediate local environment is noted as a possible cause of prevalent biculturalism. Limitations and future directions for the research on ethnic identity development and acculturation are also discussed.

Applying general strain theory to examine perceived discrimination's indirect relation to Mexican-heritage youth's alcohol, cigarette, and marijuana use.

Latent growth curve modeling was used to test four hypotheses. First, this study hypothesized that acculturation-related variables (e.g., Mexican-heritage youth's country of origin, time spent in the U.S., and language preference with family and friends) would be associated with initial levels of perceived discrimination. Guided by general strain theory (GST), this study then posed a second hypothesis: Initial levels of perceived discrimination would be indirectly related to initial levels of substance use through initial levels of acculturation stress. Third, this study hypothesized that changes in perceived discrimination would be indirectly related to changes in substance use through changes in acculturation stress. As a fourth hypothesis, it was postulated that initial levels of perceived discrimination would be indirectly related to changes in substance use through changes in acculturation stress. Mexican-heritage youth (N = 1,106) from 29 schools in Phoenix, AZ completed surveys at six waves from 5th through 8th grades. In partial support of the first hypothesis, more time spent in the U.S. and speaking English with friends were associated with lower levels of perceived discrimination. The second hypothesis was not supported. Initial levels of perceived discrimination were positively associated with initial levels of acculturation stress; however, this association was not found between initial levels of acculturation stress and substance use. The third and fourth hypotheses were supported, which buttressed predictions derived from GST. Both initial levels and increases in perceived discrimination were indirectly related to increases in substance use through increases in acculturation stress.

Mexican-heritage preadolescents' ethnic identification and perceptions of substance use.

This paper examines the relationship between ethnic identification and substance use for 1,346 Mexican-heritage preadolescents in a National Institute on Drug Abuse-funded study in Phoenix, Arizona (2004-2005). Participants ranged from 9 to 13 years old, 49% reported their gender as male, 33% self-identified as Mexican, and 67% as Mexican American, and 91% of the students reported taking part in the free or reduced-price lunch program. Questionnaire responses were analyzed by fitting regression models. Analyses showed that ethnic identification may play a protective role, with stronger ethnic identification related to more antidrug norms, less positive drug expectations, stronger refusal efficacy, and less intent to use substances. While gender did not significantly moderate the relationships, ethnic identification appears more broadly related to antisubstance-use norms for Mexican-born than U.S.-born participants. This study presents important implications for substance-use prevention research among Mexican heritage preadolescents. Finally, limitations of the study are noted.

Extending the theory of planned behavior to predict alcohol, tobacco, and marijuana use among youth of Mexican heritage.

This study examined the applicability of extending the theory of planned behavior to explain the normative processes in substance use among Mexican-heritage youth. The theory identifies norms, attitudes, and perceived behavioral control as predictors of intentions, which in turn, predict behaviors. To date, the theory had a limited conceptualization of norms and had not been extended to youth of Mexican descent, one of the fastest growing segments of the U.S. population and one at particular risk for alcohol, tobacco, and marijuana use. Based on norm focus theory, it was hypothesized that norms are multidimensional, consisting of parental injunctive, peer injunctive, descriptive, and personal substance use norms. Second, it was hypothesized that parental injunctive, peer injunctive, and descriptive norms indirectly affect substance use intentions through attitudes, personal norms, and perceived behavioral control. The third hypothesis postulated that the model would operate differently based on Mexican-heritage youths' country of origin. Mexican-heritage youth (N = 1,499) from 30 elementary schools in Phoenix, AZ completed questionnaires in three waves over 18 months as part of a larger study. The findings supported the first hypothesis, showing the multidimensionality of norms. The second hypothesis was partially supported by findings from a multi-group multilevel path analysis using Mplus. Descriptive norms' association with intentions was partially mediated by attitudes, personal norms, and perceived behavioral control, while parental and peer injunctive norms were fully mediated, partially supporting the second hypothesis. Contrary to the third hypothesis, the mediation model did not differ based on Mexican-heritage youths' country of origin.

Substance use, resistance skills, decision making, and refusal efficacy among Mexican and Mexican American preadolescents.

This article examines the relationships among resistance skills, refusal efficacy, decision-making skills, and substance use for a sample of Mexican and Mexican American 5th grade students who were attending public schools in Phoenix, Arizona. An analysis of self-report questionnaire data indicated that the likelihood that male students reported ever having used one or more substances increased as they reported a greater willingness to use passive decision-making (e.g., going along) and decreased as they reported greater refusal efficacy and a greater willingness to utilize active decision making (e.g., thoughtful processing). No significant relationships emerged between the 4 predictors and lifetime substance use among the girls. These findings support the role of social skills in substance use prevention, shed light on an understudied group, and suggest the importance of continuing to examine gender differences in skills-based interventions.

The Effects of Mexican origin family structure on parental monitoring and pre-adolescent substance use expectancies and substance use.

Substance use among Mexican origin, low-income youths is a serious, but under-studied problem. This study examines the relationship between the structure of Mexican origin families (i.e. nuclear, single-parent, blended or extended), and the parental monitoring, substance use expectancies, and substance use reported by pre-adolescents. Family structure did not differentiate the substance use prevalence, expectancies or parental monitoring among the 1224 low-income, Mexican-origin fifth grade participants. Parents from all family types demonstrated similar levels of parental monitoring. More importantly, family composition was not related to pre-adolescents' substance use. Other analyses showed that the relationship between substance use and certain demographic variables (e.g. gender, country of birth, language use) did not differ across family structures. The report concludes by discussing possible developmental and resiliency factors in Mexican origin families that would account for these findings.

Mexican/Mexican American Adolescents and keepin' it REAL: An Evidence-Based Substance Use Prevention Program.

A randomized trial tested the efficacy of three curriculum versions teaching drug resistance strategies, one modeled on Mexican American culture; another modeled on European American and African American culture; and a multicultural version. Self-report data at baseline and 14 months post-intervention were obtained from 3, 402 Mexican heritage students in 35 Arizona middle schools, including 11 control sites. Tests for intervention effects used simultaneous regression models, multiple imputation of missing data, and adjustments for random effects. Compared with controls, students in the Latino version reported less overall substance use and marijuana use, stronger intentions to refuse substances, greater confidence they could do so, and lower estimates of substance-using peers. Students in the multicultural version reported less alcohol, marijuana, and overall substance use. Although program effects were confined to the Latino and multicultural versions, tests of their relative efficacy compared with the non-Latino version found no significant differences. Implications for evidence-based practice and prevention program designs are discussed, including the role of school social workers in culturally grounded prevention.

Ethnicity and ethnic identity as predictors of drug norms and drug use among preadolescents in the US Southwest.

This article reports the results of research exploring how ethnicity and ethnic identity may "protect" adolescents against drug use and help them form antidrug use norms. This study was conducted in 1998 and is based on a sample of 4364 mostly Mexican American seventh graders residing in a large southwestern city of diverse acculturation statuses. It aims at testing existing findings by conducting the research within the unique geographic and ethnic context of the Southwest region of the United States. This research examines how strength of ethnic identity plays a distinctive role in drug use behavior among the various ethnic groups represented in the sample: Mexican Americans, other Latinos, American Indians, African Americans, non-Hispanic Whites, and those of mixed ethnic backgrounds. Positive ethnic identity (i.e., strong ethnic affiliation, attachment, and pride) was associated with less substance use and stronger antidrug norms in the sample overall. Unexpectedly, the apparently protective effects of positive ethnic identity were generally stronger for non-Hispanic White respondents (a numerical minority group in this sample) than for members of ethnic minority groups. Implications for prevention programs tailored for Mexican/Mexican American students are discussed.
