Abstract [en]

Twelve-month well-being outcomes were investigated for 835 participants in 1 of 2 randomized controlled trials offering online assessment and brief intervention for either problematic alcohol (n = 633) or drug use (n = 202). The well-being of participants who had reduced their substance use to a less problematic level (regardless of intervention) over 12 months was compared with that of participants who had maintained or increased their use. At a 12-month follow-up, the 227 alcohol trial participants with reduced use showed better well-being in comparison to the 406 with stable or increased use, in physical health and sleep quality, as well as general well-being, ability to concentrate, lower stress, better social life satisfaction and sense of control, and a lower rate of depressed mood. Among the 70 drug trial participants who had reduced their drug use over 12 months, 80% had ceased all drug use, and at follow-up they had fewer alcohol-related problems than the stable group. No differences in well-being between these groups were identified. Self-reported access to additional treatment modalities beyond the trial interventions (e.g., speaking to someone about problematic use and accessing additional Internet-based interventions) was higher among participants in both cohorts with reduced substance use in comparison to those with stable/increased use. Drug users who reduced their use accessed prescribed medication to a larger extent than those whose use remained stable or increased. Points to consider when conducting future research on well-being and problematic substance use are discussed.
