God Forbid! Substance Use Among Religious and Nonreligious Youth

Among a predominantly Mexican and Mexican American sample of preadolescents, religiosity protected against lifetime alcohol, cigarette, and marijuana use and recent alcohol and cigarette use when religious affiliation was controlled. When religiosity was controlled, however, adolescents with no religious affiliation and adolescents who were religiously affiliated reported similar substance use outcomes. Interaction effects demonstrated that the protective effect of greater religiosity operated more strongly in some religions than in others for selected outcomes. Overall, the impact of religiosity on reported drug use did not differ significantly for more and less acculturated Latino youth.

The protective and risk effects of parents and peers on substance use, attitudes and behaviors of Mexican and Mexican American female and male adolescents.

This study explores the extent to which parental and peer behaviors and norms may affect substance use, personal antidrug norms, and intentions to use drugs in a group of Mexican heritage preadolescents in the Southwest United States, and whether these parental and peer influences differ according to gender. Secondary data from a randomized trial of a drug prevention program were used. The sample consisted of 2,733 adolescents. The outcomes were recent alcohol, cigarette, and marijuana use, personal antidrug norms, and intentions to use drugs. In this study, peer variables were more consistently related to the outcomes than parent variables, with the exception of parental injunctive norms, which were the most predictive parent factor. Recommendations are provided to further study the protective processes that are maintained through the transition into adolescence and acculturation as a foundation for the design of resiliency-focused prevention interventions.

Perceived Ethnic Discrimination versus Acculturation Stress: Influences on Substance Use among Latino Youth in the Southwest∗:

Using a predominately Mexican-origin Latino sample of 5th grade students from the Southwestern United States, this study examined the relative effects of perceived discrimination and acculturation stress on substance use, and it assessed whether these effects were moderated by linguistic acculturation or time in the United States. Although rates of substance use were generally low in the sample, given the young age of the participants, over half (59%) of the sample perceived some discrimination, and almost half (47%) experienced some acculturation stress. Spanish-dominant and bilingual youth perceived more discrimination than English-dominant youth, whereas youth who have been in the United States five or fewer years perceived more discrimination than youth with more time in the United States. Youth who were Spanish-dominant or were recent arrivals experienced the most acculturation stress, with levels declining as linguistic acculturation and time in the United States increased. Multiple regression estimates indicated that perceived discrimination was associated with larger amounts and higher frequency of recent substance use and an array of substance use attitudes, such as stronger intentions to use substances, espousal of pro-drug norms, more positive substance use expectancies, and peer approval of substance use. Although acculturation stress was not associated with substance use, it was positively associated with several substance use attitudes, which are known antecedents of actual use. With a few exceptions, linguistic acculturation and time in the United States did not moderate the effects of perceived discrimination or acculturation stress.

Neighborhood Effects on Youth Substance Use in a Southwestern City

This study examines neighborhood influences on alcohol, cigarette, and marijuana use among a predominantly Latino middle school sample. Drawing on theories of immigrant adaptation and segmented assimilation, the authors test whether neighborhood immigrant, ethnic, and socioeconomic composition, violent crime, residential instability, and family structure have differential effects on substance use among youth from different ethnic and acculturation backgrounds. Data are drawn from self-reports from 3,721 seventh-grade students attending thirty-five Phoenix, Arizona, middle schools. Analysis was restricted to the two largest ethnic groups, Latino students of Mexican heritage and non-Hispanic Whites. After adjusting for individual-level characteristics and school-level random effects, only one neighborhood effect was found for the sample overall, an undesirable impact of neighborhood residential instability on recent cigarette use. Subgroup analyses by individual ethnicity and acculturation showed more patterned neighborhood effects. Living in neighborhoods with high proportions of recent immigrants was protective against alcohol, cigarette, and marijuana use for Latino students at different acculturation levels, whereas living in predominantly Mexican heritage neighborhoods (mostly nonimmigrants) was a risk factor for alcohol and marijuana use for less acculturated Latinos. There were scattered effects of neighborhood poverty and crime, which predicted more cigarette and alcohol use, respectively, but only among more acculturated Latinos. Inconsistent effects confined to bilingual and more acculturated Latinos were found for the neighborhoods proportion of single-mother families and its residential instability. No neighborhood effects emerged for non-Hispanic White students. Results suggested that disadvantaged neighborhoods increase substance use among some ethnic minority youth, but immigrant enclaves appear to provide countervailing protections.

Body image, acculturation, and substance abuse among boys and girls in the Southwest.

This study explored body image as measured by perceptions of weight and appearance and its impact on adolescent drug use among predominately Mexican American middle school students in the southwest. Outcomes analyzed included lifetime and recent alcohol, cigarette, and marijuana use and antidrug norms. Disliking ones looks was more of a risk factor for boys, whereas negative weight perceptions were more of a risk factor for girls. Relative to more acculturated (English-dominant) Latinos (N = 903), non-Latino Whites (N = 121), and other non-Latino youth (N = 107), less acculturated (Spanish-dominant) Latino youth (N = 212) reported the poorest body image. However, more acculturated Latino youth with poor body image had the greatest risk of substance use. More acculturated Latino boys who disliked their looks reported relatively greater amounts of recent alcohol use, and those who rated their bodies as too thin reported higher lifetime cigarette use, a greater amount and frequency of recent cigarette use, and weaker antidrug norms. More acculturated Latina girls who thought they were too fat reported a greater amount and frequency of recent cigarette use. These findings suggest that low levels of acculturation may protect some Latino youth with poor body image from coping via substance use. In addition, they suggest that poor body image among some Latinos may result less from adoption of American thinness ideals but rather from attitudes and behaviors that devalue the characteristics of Latino appearance.

Promoting Reduced and Discontinued Substance Use among Adolescent Substance Users: Effectiveness of a Universal Prevention Program

Efforts to address youth substance use have focused on prevention among non-users and treatment among severe users with less attention given to youth occupying the middle ground who have used substances but not yet progressed to serious abuse or addiction. Using a sample from 35 middle schools of 1,364 youth who reported using substances, this study examined the effectiveness of a universal youth substance use prevention program, the SAMHSA Model Program keepin’ it REAL, in promoting reduced or recently discontinued alcohol, cigarette, and marijuana use. Discrete-time event history methods modeled the rates of reduced and recently discontinued use across four waves of data. Each substance (alcohol, cigarettes, and marijuana) was modeled separately. Beginning at the second wave, participants who reported use at wave 1 were considered at risk of reducing or discontinuing use. Since the data sampled students in schools, multi-level models accounted for the nesting of data at the school level. Results indicated that prevention program participation influenced the rates of reduced and recently discontinued use only for alcohol, controlling for baseline use severity, age, grades, socioeconomic status, ethnicity and gender. Among youth who reported use of alcohol in wave 1 (N=1,028), the rate of reducing use for program participants was 72% higher than the rate for control students. The rate of discontinuing use was 66% higher than the rate for control students. Among youth who reported use of one or more of the three substances in wave 1 (N=1,364), the rate of discontinuing all use was 61% higher for program participants than for control students. Limitations and implications of these findings and plans for further research are discussed.

Effects of Parental Monitoring, Permissiveness, and Injunctive Norms on Substance Use Among Mexican and Mexican American Adolescents.

The prevention literature has given little attention to how parental influences affect substance use among Mexican origin adolescents, even though they form part of the largest ethnic minority group in the United States. This study explored the effects of three types of parental influences– parental monitoring of the childs whereabouts, degree of parental permissiveness, and the strength of parental injunctive norms discouraging substance use–on alcohol, cigarette, and marijuana use and anti-drug norms. Results showed that parental permissiveness and parental injunctive norms, particularly anti-drug injunctive norms, had the strongest effects on the substance use outcomes, but parental monitoring generally was not a significant predictor. These results and implications for prevention are discussed in light of Mexican cultural norms toward substance use, gender roles, and family roles.

When to intervene: elementary school, middle school or both? Effects of keepin' it REAL on substance use trajectories of Mexican heritage youth.

This article presents the findings of a study exploring two questions: What age is most efficacious to expose Mexican heritage youth to drug abuse prevention interventions, and what dosage of the prevention intervention is needed? These issues are relevant to Mexican heritage youth—many from immigrant families—in particular ways due to the acculturation process and other contextual factors. The study utilized growth curve modeling to investigate the trajectory of recent substance use (alcohol, cigarettes, marijuana, inhalants) among Mexican heritage students (N = 1,670) participating in the keepin’ it REAL drug prevention program at different developmental periods: the elementary school (5th grade), middle school (7th grade), or both. The findings provide no evidence that intervening only in elementary school was effective in altering substance use trajectories from 5th to 8th grade, either for licit nor illicit substances. Implementing keepin’ it REAL in middle school alone altered the trajectories of use of all four substances for Mexican heritage youth. A double dose of prevention, in elementary and middle school proved to be equally as effective as intervening in 7th grade only, and only for marijuana and inhalants. The decrease in use of marijuana and inhalants among students in the 7th-grade-only or the 5th- and 7th-grade interventions occurred just after students received the curriculum intervention in 7th grade. These results are interpreted from an ecodevelopmental and culturally specific perspective and recommendations for prevention and future research are discussed.

Immigrant advantage? Substance use among Latin American immigrant and native-born youth in Spain

This article reports the results of a descriptive study conducted with middle school and high school age youth residing in northwestern Spain. The main outcome of the study is to advance knowledge about the drug use attitudes and behaviors of immigrants versus native youth in a social context where Latin American immigrants share a common language and a set of core cultural norms with the host society. The research was conducted by a bi-national Spain–US research team as a preliminary study leading to the development of joint culturally appropriate prevention interventions for youth in the northern region of Galicia, Spain. Surveys were administered in Spring 2005 to 817 students in 7th to 10th grades in 10 urban, secondary schools with high immigrant enrollment. The sample included Spanish natives (two-thirds) and Latin American immigrants (one-third), mainly from Colombia, Argentina, and Venezuela. Multiple regression analyses predicted substance use intentions, and a composite variable measuring lifetime and last 30-day frequency and amount of alcohol, cigarette and marijuana use. Controlling for the fact that the immigrant students were generally older and performing less well academically than natives, and for other predictors, Latin American immigrant youth were less at risk than native youth on their intentions to use substances and on their reported actual substance use. In a mediational analysis, most of the key explanatory variables in youth substance use etiology failed to account for the immigrant versus native differences, including a range of risk and protective factors for substance use, substance use norms, strength of ethnic identity, and degree of social integration within native-born social networks. Differential access to drugs mediated the immigrant–native gap in substance use intentions but did not mediate differences in actual substance use.

Acculturation among Mexican-heritage preadolescents: A latent class analysis

This study applies advanced conceptualization and measurement to an analysis of acculturation among 1,632 Mexican-heritage preadolescents. We assessed whether - and how - multiple measures combine to form a latent acculturation construct that groups individuals into classes; and determine how many and what classes (or types) of acculturation are experienced by this sample of 5(th) graders. Measures included attitudinal, behavioral, and linguistic acculturation, generation status, time in the U.S., ethnic identification, and contact with the culture of origin. The analysis identified five classes of acculturation, differing in size and characterized by specific measures of acculturation: less acculturated, moderately bicultural, strongly bicultural, highly acculturated, and marginalized. Although most youths fell into the first four classes, consonant with their exposure to American society, a small minority of youths fell into the last class. Despite substantial exposure to U.S. culture and recent exposure to Mexican culture, these youth showed little affinity for either culture.
