Abstract: Alcohol use is a leading cause of burden of disease among young people. Prevention strategies can be effective in the short-term however little is known about their longer-term effectiveness. The aim of this study was to examine the sustainability of universal, selective, and combined alcohol use prevention across the critical transition period from adolescence into early adulthood. In 2012, a total of 2190 students (mean age, 13.3 years) from 26 Australian high schools participated in a cluster randomized controlled trial and were followed up for 3 years post baseline. Schools were randomly assigned to deliver the following: (1) universal Web-based prevention for all students (Climate Schools) (2) selective prevention for high-risk students (Preventure) (3) combined universal and selective prevention (Climate Schools and Preventure [CAP]) or (4) health education as usual (control). This study extends the follow-up period to 7-years post baseline. Primary outcomes were self-reported frequency of alcohol consumption and binge drinking, alcohol-related harms, and hazardous alcohol use, at the 7-year follow-up. At 7-year follow-up, students in all 3 intervention groups reported reduced odds of alcohol-related harms compared to the control group (odds ratios [ORs] = 0.13-0.33), and the Climate (OR = 0.04) and Preventure (OR = 0.17) groups reported lower odds of hazardous alcohol use. The Preventure group also reported lower odds of weekly alcohol use compared to the control group (OR = 0.17), and the Climate group reported lower odds of binge drinking (OR = 0.12), holding mean baseline levels constant. This study demonstrated that both universal and selective preventive interventions delivered in schools can have long-lasting effects and reduce risky drinking and related harms into adulthood. No added benefit was observed by delivering the combined interventions.

Abstract: Prospective research is needed to better-understand changes in substance use from before to during the coronavirus disease (COVID-19) pandemic, among emerging adults (18-25 years), a high-risk group for substance use. Full s le analyses revealed decreased binge drinking ( Changes in alcohol and cannabis use frequency among emerging adults in the first 3 months of COVID-19 largely differed according to prepandemic substance use, COVID-19-related factors, and preexisting factors. While some youth with preexisting vulnerabilities (e.g., more frequent substance use prepandemic) remained stable or decreased their substance use during COVID-19, emerging adults who experienced employment loss, loneliness, and financial concerns during COVID-19 increased their substance use, highlighting the need for increased supports for vulnerable populations.

Abstract: This study investigated the validity of a brief personality screening measure for substance use in adolescents, the Substance Use Risk Profile Scale (SURPS), among Australian adolescents. A total of 527 adolescents (mean age: 13.38years, SD=0.43) from seven Australian schools were assessed at two time points 24months apart. The concurrent and predictive validity of the SURPS was determined using a series of linear and logistic regressions, and was compared to the results in a United Kingdom (UK) s le. SURPS subscale scores for the Australian population were also reported and compared to those in the UK. Overall, the SURPS subscale scores for Australian adolescents were similar to those for adolescents from the UK. Tests of concurrent and predictive validity in the Australian s le demonstrated that the all four personality profiles - Hopelessness (H), Anxiety Sensitivity (AS), Impulsivity (IMP), and Sensation Seeking (SS) - were related to measures of substance use and other behavioural and emotional characteristics. In addition, all the predicted specific prospective relationships between the personality profiles and particular substance use and other behavioural problems were confirmed except that H was not associated with illicit drug use. Overall, the results were similar between the Australian and UK s les. The SURPS is a valid and useful measure for identifying Australian adolescents at high-risk for substance use and other emotional and behavioural problems. Implications for prevention are discussed.

Abstract: Selective school-based alcohol prevention programs targeting youth with personality risk factors for addiction and mental health problems have been found to reduce substance use and misuse in those with elevated personality profiles. To report 24-month outcomes of the Teacher-Delivered Personality-Targeted Interventions for Substance Misuse Trial (Adventure trial) in which school staff were trained to provide interventions to students with 1 of 4 high-risk (HR) profiles: anxiety sensitivity, hopelessness, impulsivity, and sensation seeking and to examine the indirect herd effects of this program on the broader low-risk (LR) population of students who were not selected for intervention. Cluster randomized controlled trial. Secondary schools in London, United Kingdom. A total of 1210 HR and 1433 LR students in the ninth grade (mean [SD] age, 13.7 [0.33] years). Schools were randomized to provide brief personality-targeted interventions to HR youth or treatment as usual (statutory drug education in class). Participants were assessed for drinking, binge drinking, and problem drinking before randomization and at 6-monthly intervals for 2 years. Two-part latent growth models indicated long-term effects of the intervention on drinking rates (β = -0.320, SE = 0.145, P = .03) and binge drinking rates (β = -0.400, SE = 0.179, P = .03) and growth in binge drinking (β = -0.716, SE = 0.274, P = .009) and problem drinking (β = -0.452, SE = 0.193, P = .02) for HR youth. The HR youth were also found to benefit from the interventions during the 24-month follow-up on drinking quantity (β = -0.098, SE = 0.047, P = .04), growth in drinking quantity (β = -0.176, SE = 0.073, P = .02), and growth in binge drinking frequency (β = -0.183, SE = 0.092, P = .047). Some herd effects in LR youth were observed, specifically on drinking rates (β = -0.259, SE = 0.132, P = .049) and growth of binge drinking (β = -0.244, SE = 0.073, P = .001), during the 24-month follow-up. Findings further support the personality-targeted approach to alcohol prevention and its effectiveness when provided by trained school staff. Particularly novel are the findings of some mild herd effects that result from this selective prevention program. clinicaltrials.gov Identifier: NCT00776685.
