The current study explored the relationships between parenting practices and adolescent drug use. Suburban middle school students (N = 2129) completed survey that included measures of perceived parental monitoring, discipline and setting an anti-drug message as well as measures of drug-related knowledge, attitudes and peer norms. Results indicated that effective parenting practices had a direct protective effect in terms of adolescent drug use and that the protective effect of parenting practices remained signifcant after including the effects of parenting on adolescent drug-related knowledge, attitudes and perceived norms in a structural equation model. These findings suggest that effective parenting practices have a robust protective effect on youth drug use via multiple pathways that extend beyond parenting effects on the most proximal predictors of adolescent drug use.

The purpose of this study was to determine if ethnic and gender differences in polydrug use exist among a cohort of inner-city adolescents during the three-year middle school period. Students in 22 urban schools completed self-report questionnaires with measures of drug use (smoking, drinking, and marijuana use) at three annual assessments. For participating students, (N=2354), analyses of variance were conducted to test for ethnic group (Asian, Black, Hispanic, White) and gender differences in polydrug use. Ethnic differences were found for polydrug use measures at each assessments point. Asian and Black adolescents generally reported less polydrug use than White and Hispanic youth. When gender differences were evident, boys engaged in more use than girls. The relatively high rates of polydrug use indicate that prevention intervention programs that target multiple substances may be more efficient in reducing overall risk than prevention programs that focus on a single substance (e.g., smoking prevention only).

Vulnerability to adolescent alcohol use is often predicated on low social competence and poor social resistance skills. As a result, many prevention programs focus on improving assertiveness and drug-specific refusal skills to build resilience. However, individual differences in the rate at which youth acquire these skills may regulate their degree of alcohol use. The current study used longitudinal growth curve modeling with four-year panel data to examine the dynamic relations between refusal skills and alcohol use. Additional variables of theoretical interest that were controlled for included gender, risk-taking, grades, social competence, and self-control. The estimated means for alcohol use indicated that on average these adolescents increased their alcohol us by a factor of 140% over a four-year period. Refusal skill efficacy declined by a factor of 13% over the same time frame. Higher initial skill level predicted a slower rate of alcohol usage; conversely higher initial alcohol use predicted a slower acquisition of refusal skills. Grades enhanced the rate of refusal skill acquisition and females acquired refusal skills faster than males. Socially competent youth declined more rapidly in their refusal ability and increased their alcohol use more rapidly than youth with low social competence. Self-control was associated with lower initial levels of alcohol use and higher initial level of refusal skills. These findings support a dual focus on social resistance skills and personal self-control strategies to reduce motivations for alcohol use. [ABSTRACT FROM AUTHOR]
