Gang membership, gender, and sexual behavior in and outside a romantic relationship.

Prior research consistently finds that gang youth, compared to nongang youth, are more involved in risky behaviors such as violence and drug sales. Less attention has been given to comparisons in sexual behavior. While research demonstrates that gang membership is associated with risky sex and many gang members indicate that sex is a motivation for joining a gang, prior research is limited in its ability to account for self-selection into a gang, variations in involvement across gender, and different forms of sexual activity. This research addresses these limitations by using Add Health data and propensity score matching to examine the relationship between gang membership and sexual behavior inside and out of a romantic relationship as well as how this relationship differs by gender. While findings indicate that gang membership increases the likelihood of sexual intercourse, nonromantic sex, and the number of nonromantic sex partners, no unique gender differences were identified.

A Quasi-Experimental Evaluation of a School-Based Prescription Opioid Misuse Education Program.

The use of prescription opioids is a matter of concern among academics and practitioners, but there remains a lack of programming to target this issue. One program, This Is (Not) About Drugs (TINAD), is intended to address part of this need by altering youth perceptions of the risks associated prescription opioid misuse as well as heroin. This study presents results from a quasi-experimental evaluation of TINAD. Propensity score matching techniques were used to account for selection effects across treatment and comparison groups. Program participants demonstrated increases in understanding of the similarities between prescription opioids and heroin and the risks associated with prescription opioid misuse. While these results are promising, TINAD requires a more rigorous evaluation of its effectiveness.

The highs that bind: school context, social status and marijuana use.

Substance use has been closely linked with the structural characteristics of adolescent social networks. Those who drink, smoke, and use drugs typically enjoy an elevated status among their peers. Rates of substance use vary substantially across schools, and indicators of school structure and climate account for at least part of this variation. Emerging research suggests peer-group processes are contingent on school context, but questions remain regarding the school-level mechanisms which condition the influence of network characteristics on substance use. The present study uses multilevel logistic regression models to examine the moderating influence of school connectedness, school drug culture, and global network density on the association between peer network status and marijuana use. The analyses draw on self, peer, and parental data from a sample of 7,548 high-school aged youth nested within 106 schools participating in the National Longitudinal Study of Adolescent to Adult Health (mean age = 15.2; % white = 59 %; male = 45 %). The results indicate that school connectedness significantly reduces the effect of social status on marijuana use. This provides evidence that school-level mechanisms can reduce the instrumentality of marijuana consumption in the status attainment process in adolescence.
