The Passports study was funded by National Health and Medical Research Council (NHMRC) Strategic Award APP409966 and NHMRC Project Grant APP1002463. T1 - The predictive validity of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) for moderate- to high-risk cannabis, methamphetamine and opioid use after release from prison ![]() Addiction published by John Wiley & Sons Ltd on behalf of Society for the Study of Addiction.", We calculated the area under the receiver operating characteristic curve (AUROC) and the optimal ASSIST cut-off score for each substance, using Youden 2023 The Authors. Post-incarceration substance use was measured at 1, 3 and 6 months after release. ![]() Measurements: The ASSIST was used to assess problematic use of cannabis, methamphetamine, heroin and other non-prescribed opioids in the 3 months before incarceration. Participants: A total of 1054 adults within 6 weeks of expected release from prison. Setting: Prisons in Queensland, Australia. ![]() Design: A longitudinal design with baseline survey conducted between 20 in the 6 weeks before expected prison release and up to three follow-up surveys in the 6 months after release. We aimed to assess the predictive validity of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) for returning to substance use after release from prison. The substantial rates of returning to substance use after release from prison suggest that prison serves to interrupt rather than cease substance use.Ībstract = "Background and aims: Illicit substance use is common among people entering prisons, as is returning to substance use after release from prison. AUROCs for other drugs ranged from 0.73 to 0.79.Ĭonclusions: The ASSIST shows promise as an accurate and potentially scalable tool that may be useful for predicting a return to substance use after release from prison and could inform service delivery. Using these cut-offs, the AUROC was highest for heroin in predicting both any use (AUROC = 0.82) and weekly use (AUROC = 0.88) in the past 4 weeks. The optimal ASSIST cut-off score was ≥ 4 for heroin, methamphetamine and cannabis and ≥ 1 for other opioids. We calculated the area under the receiver operating characteristic curve (AUROC) and the optimal ASSIST cut-off score for each substance, using Youden’s index (J).įindings: Forty-one per cent (n = 434) of the cohort reported any substance use during follow-up: 33% (n = 344) used cannabis, 20% (n = 209) methamphetamine, 10% (n = 109) heroin and 9% (n = 97) illicit other opioids. ![]() We aimed to assess the predictive validity of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) for returning to substance use after release from prison.ĭesign: A longitudinal design with baseline survey conducted between 20 in the 6 weeks before expected prison release and up to three follow-up surveys in the 6 months after release.
