Aims: The purpose of this study was to compare the preliminary efficacy of a computer-assisted intervention (CAI), in which a computer-delivered intervention was immediately followed up with a brief therapist review session, to a therapist-delivered intervention (TDI) for adolescent substance use. Design, Setting, and Participants: Both conditions were examined in a pilot randomized clinical trial. All participants were recruited from a family court in the northeast United States. The sample included a total of 36 adolescents court-referred for an adolescent substance-related offense.Measures: Measures included adolescent alcohol and marijuana-use frequency, quantity, and problems as well as self-efficacy to resist the urge to use.Findings: While no significant time-by-condition differences were noted between the CAI and TDI conditions, significant time effects were found for both the TDI and CAI indicating a decrease in the total number of alcohol- or marijuana-use days over the six-month follow-up period.Conclusions: Given that CAIs are inexpensive, require minimal training, can be implemented with a high degree of fidelity, and are portable when compared to some TDIs, their use for decreasing substance use and related problems, particularly among adolescents with low access to substance-use interventions, seems promising. A fully powered trial of CAI efficacy is indicated.

Exactly two years after a large survey of substance use among secondary school adolescents in London in 1987 (Swadi, 1988), a similar survey among a sub-sample using the same questionnaire was carried out. Of 242 second- and third-year pupils from one of the six schools in the original sample, 219 were available for the follow-up. In 1989 they were in the fourth and fifth years; the sexes were equally represented. The follow-up survey aimed to investigate the trends with respect to the prevalence of use of various drugs and to investigate the effect of the absence of a specific drug-prevention programme on such trends. Comparisons are also made with survey results from the fourth and fifth year at the same school in 1987.

AbstractNeurodevelopmental explanations for adolescent substance use have focused on heightened sensitivity of the brain’s reward system, centered around the ventral striatum (VS). Recent evidence demonstrates increased functional connectivity between the VS and hippocampus in adolescents relative to adults, suggesting that the adolescent brain may learn from subsequent exposure to risks/rewards. However, a link between VS-hippocampal circuitry and adolescent substance use has yet to be established. Two separate longitudinal studies were conducted to evaluate whether variation in VS-hippocampal resting-state functional connectivity (rs-FC) predicts subsequent adolescent substance use. Study 1 consisted of 19 youth recruited from a high sociodemographic risk population (N = 19; 14 female; 47% Black Non-Hispanic, 32% White Non-Hispanic). To replicate results of Study 1, Study 2 utilized data from the National Consortium on Adolescent Neurodevelopment and Alcohol, an ongoing multi-site imaging study (N= 644; 339 female; 11% Black Non-Hispanic, 11% Hispanic/Latino, 66% White Non-Hispanic). Resting-state fMRI data were collected at a baseline time point and lifetime and past year self-reported substance use was collected at a follow up visit. Regression models tested whether baseline VS-hippocampal rs-FC predicted substance use at follow up. Across both studies, higher VS-hippocampal rs-FC at baseline predicted greater substance use at follow up. These data provide the first evidence linking increased VS-hippocampal connectivity with greater adolescent substance use. Results fit with the emerging idea that adolescent substance use is driven by not only a heightened sensitivity to reward, but also a stronger link between reinforcement learning and episodic memory for rewarding outcomes.
