Gender-based differences in abstention and desistance from drug use among American Indian adolescents

Informed by the social control theoretical perspective, this study intends to identify the factors more likely to differentiate American Indian (AI) adolescents who never used illicit drugs (abstainers) and those who used drugs in the past but did not report recent drug usage (desisters) from their peers who reported lifetime and recent drug usage (persisters). This secondary analysis is based on data from a multi-site study conducted between 2009 and 2013. It is based on a gender-balanced sample (N = 3,380) of AI adolescents (50.50% male; Mean age = 14.75; SD = 1.69) representing the major AI languages and cultural groups in the U.S. Half of the AI adolescents reported lifetime drug use (50.40%), 37.50% never used drugs, and 12.10% stopped using drugs. When controlling for the variables included in the analysis, AI boys were significantly more likely than AI girls to desist from drug use. Both boys and girls who never used drugs tended to be younger, were less likely to have delinquent friends and a lower level of self-control, had stronger bonds to school, but lower levels of family attachment, and reported increased parental supervision. Compared to drug users, desisters associated significantly less with delinquent peers. While school attachment, self-control, and parental monitoring did not differentiate female desisters from female drug users, adolescent boys who desisted from drug use were more likely to report higher levels of school attachment and parental monitoring and their level of self-control was less likely to be low.

Longitudinal associations between adolescent out-of-school time and adult substance use

INTRODUCTION

Based on Bronfenbrenner's bioecological theory and Bornstein's specificity principle, the purpose of this study was to examine adolescents' time in out-of-school settings as a precursor of three types of problematic substance use in adulthood (i.e., binge drinking, regular marijuana use, and use of illicit drugs).

METHOD

Adolescents (N = 978) reported the time they spent in four common out-of-school settings at ages 15 and 18: unsupervised time with peers, organized sports, other organized activities, and paid employment. At age 26, participants reported binge drinking, marijuana use, and illicit drug use.

RESULTS AND CONCLUSIONS

Adolescents' time in out-of-school settings during high school predicted age 26 substance use over and above family and adolescent factors, including adolescents' substance use during high school. Adolescents' unsupervised time with peers increased the odds and frequency of binge drinking and regular marijuana use at age 26. Time in high school organized sports increased the odds of binge drinking at age 26, but not marijuana or illicit drug use. Time spent in other organized activities, such as community service and the arts, lowered the odds of illicit drug use whereas paid employment in high school was not related to age 26 substance use. Aligned with Bornstein's specificity principle, time spent in specific out-of-school settings during adolescence were differentially related to substance use problems in early adulthood, with some activities serving as a risk factor and other activities serving as a protective factor for young adults.
