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.

Estimating person--environment transactions on intention to change drug-using behaviors

The community attachment model of addiction is an ecologically based social process model that suggests social context referents (peers, family, neighbors, etc.) will influence attachment to addiction or recovery communities, via cognitive, affective, and behavioral commitments. This study examined the influence of social context referents on intention to change drug using behavior, and examined moderating effects of three contextual indicators (labor market attachment, educational attainment, and family poverty status) on these relationships. The study sample consisted of 302 adults in inpatient and outpatient substance abuse treatment facilities, who completed a set of instruments that included the Ecological Assessment of Substance Abuse Experiences (EASE), a new instrument designed to measure the influence of social context referents on addiction and recovery attachment processes. Results showed that all three contextual indicators moderated relationships among social context referenced attitudes, drug use concern, and intention to change drug using behaviors. Findings suggest that practitioners should attend to both microlevel orientations to social context and macrolevel contextual dimensions (e.g., labor force attachment), as both may influence behavioral change opportunities.

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.

The role of norms in explaining attitudes, intention and consumption of a common food (fish) in Vietnam

The purpose of this study is to apply the conceptual framework of the theory of planned behavior (TPB) to explain the consumption of a common food (fish) in Vietnam. We seek to understand the role of norms in explaining intention to consume, and descriptive norms is included as extensions of traditional constructs such as attitude, social norms, and perceived behavioral control. The data were derived from a cross-sectional sample of 612 consumers. Structural equation modeling was applied to test the relationships between constructs, and evaluate the reliability and the validity of the constructs. The results indicate that the models fit well with the data. Attitude, social norms, descriptive norms and behavioral control all had significantly positive effect on behavioral intention. Finally, both intention and perceived behavioral control were highly associated with the frequency of consumption of the common food investigated.

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.

Immediate and short-term effects of the 5th grade version of the keepin' it REAL substance use prevention intervention

This study assessed the immediate and short-term outcomes of adapting a culturally-grounded middle school program, keepin' it REAL, for elementary school students. After curriculum adaptation, 10 schools were randomly assigned to the intervention in 5th grade with follow-up boosters in 6th grade; 13 schools were randomly assigned to the control condition, implementing the school's pre-existing substance use prevention programming. Students (n=1566) completed a questionnaire prior to curriculum implementation and follow-up questionnaires toward the end of 5th and 6th grade. The 5th grade kiR curriculum generally appeared no more effective than the control schools' programming in changing students' resistance or decision-making skills; substance use intentions, expectancies, or normative beliefs; or lifetime and recent substance use. Such findings have implications for the age appropriateness of school-based programs.

Examining the relative importance of social context referents in predicting intention to change substance abuse behavior using the EASE

There is growing consensus across literatures that more than individual motivation and "will to change" influence whether a client will be able to make and sustain recovery-related changes to prevent drug relapse post-treatment. New areas of inquiry in the substance abuse field have proposed conceptual models that promote an integration of both individual and social context factors, which offer the opportunity for important developments in clinical practice. This study examined the influence of social context referents on clients' intention to change substance abusing behaviors. The Ecological Assessment of Substance abuse Experiences (EASE), an instrument that measures the influence of social context referents on addiction and recovery behaviors, was administered to 302 inpatient and outpatient adults in treatment for substance abuse. Results showed that the number of people in his/her social network favorable towards recovery (Beta=.222); the extent to which one personally identifies with being in recovery (Beta=.339); the perceived importance of people in the client's social network encouraging recovery-related behaviors (Beta=.369); weak beliefs that drugs will lead to positive outcomes (Beta=-.220); and strong beliefs that recovery will lead to positive outcomes (Beta=.307) were all associated with intention to change substance abusing behavior.
