Abstract
Background and aims: Efficacy of brief alcohol interventions for young adults with internalizing distress (i.e. symptoms of depression, anxiety and stress) is unclear. We tested the moderating effect of internalizing distress on the efficacy of alcohol single- and multicomponent personalized feedback interventions (PFIs).
Design: Secondary data were analyzed from a randomized controlled trial (RCT) testing the efficacy of single and multicomponent PFIs, compared with an attention-only control condition.
Setting: Participants were sampled from two West Coast universities in the United States. All study protocols were completed online.
Participants: Participants (n = 1137) were college students (63% female; Mage = 20.1 years; 62.6% non-Hispanic white) who reported on internalizing distress at baseline. Some individuals reported clinically significant symptoms (depression: mild/moderate = 24.0%, severe/extremely severe = 10.5%; anxiety: mild/moderate = 19.6%, severe/extremely severe = 11.4%; and stress: mild/moderate = 37.5%, severe/extremely severe = 6.0%).
Interventions: There were four different alcohol single-component PFIs administered and an attention-only PFI control. Alcohol PFIs varied in their complexity and single-component PFIs (i.e. personalized normative feedback) were compared with multicomponent PFI (i.e. containing additional alcohol-focused psychoeducation).
Measurements: Baseline levels of internalizing distress were measured using the summed total of the Depression, Anxiety and Stress Scales (DASS). Drinking outcomes (alcohol consumption, peak eBAC, alcohol-related consequences) were measured at baseline, 3, 6 and 12 months post-intervention.
Findings: Alcohol PFI (compared with attention-only control) reduced alcohol consumption and related consequences at 6-month [rate ratio (RR)Consumption = 0.85, P = 0.004] or 12-month follow-ups (RRConsumption = 0.76, P < 0.001; RRConsequences = 0.85, P = 0.020), regardless of baseline DASS score. Participants with higher DASS scores (compared with those with lower DASS scores) reported lower 6-month alcohol consumption after receiving a single-component intervention (RR = 0.80, P < 0.001). However, individuals with higher DASS scores (compared to those with lower DASS scores) reported more 6-month alcohol-related consequences after receiving a multicomponent intervention (RR = 0.78, P = 0.004).
Conclusions: Personalized feedback interventions may demonstrate efficacy towards reducing drinking in young adults and appear similarly beneficial across levels of internalizing distress, although lower-complexity interventions may be more efficacious.
期刊介绍：
Addiction publishes peer-reviewed research reports on pharmacological and behavioural addictions, bringing together research conducted within many different disciplines.
Its goal is to serve international and interdisciplinary scientific and clinical communication, to strengthen links between science and policy, and to stimulate and enhance the quality of debate. We seek submissions that are not only technically competent but are also original and contain information or ideas of fresh interest to our international readership. We seek to serve low- and middle-income (LAMI) countries as well as more economically developed countries.
Addiction’s scope spans human experimental, epidemiological, social science, historical, clinical and policy research relating to addiction, primarily but not exclusively in the areas of psychoactive substance use and/or gambling. In addition to original research, the journal features editorials, commentaries, reviews, letters, and book reviews.
