Abstract

Abstract: Aim: To estimate the statistical interactions between alcohol policy strength and the person‐related risk factors of sensation‐seeking, antisocial personality disorder and attention‐deficit/hyperactivity disorder related to heavy alcohol use. Design: Cross‐sectional survey. Setting: Young Swiss men living within 21 jurisdictions across Switzerland. Participants: A total of 5701 Swiss men (mean age 20 years) participating in the Cohort Study on Substance Use Risk Factors (C‐SURF). Measurements: Outcome measures were alcohol use disorder (AUD) as defined in the DSM‐5 and risky single‐occasion drinking (RSOD). Independent variables were sensation‐seeking, antisocial personality disorder (ASPD), attention‐deficit/hyperactivity disorder (ADHD) and an index of alcohol policy strength. Findings: Alcohol policy strength was protective against RSOD [odds ratio (OR) = 0.91 (0.84–0.99)], while sensation‐seeking and ASPD were risk factors for both RSOD [OR = 1.90 (1.77–2.04); OR = 1.69 (1.44–1.97)] and AUD [OR = 1.58 (1.47–1.71); OR = 2.69 (2.30–3.14)] and ADHD was a risk factor for AUD [OR = 1.08 (1.06–1.10)]. Significant interactions between alcohol policy strength and sensation‐seeking were identified for RSOD [OR = 1.06 (1.01–1.12)] and AUD [OR = 1.06 (1.01–1.12)], as well as between alcohol policy strength and ASPD for both RSOD [OR = 1.17 (1.03–1.31)] and AUD [OR = 1.15 (1.02–1.29)]. These interactions indicated that the protective effects of alcohol policy strength on RSOD and AUD were lost in men with high levels of sensation‐seeking or an ASPD. No interactions were detected between alcohol policy strength and ADHD. Conclusion: Stronger alcohol legislation protects against heavy alcohol use in young Swiss men, but this protective effect is lost in individuals with high levels of sensation‐seeking or having an antisocial personality disorder.
