Do brief alcohol interventions among unemployed at-risk drinkers increase re-employment after 15 month?

Abstract

At-risk alcohol use is associated bi-directionally to unemployment, and decreases chances of re-employment. Brief alcohol interventions (BAI) can reduce at-risk alcohol use. This study aimed to investigate 15-month effects of BAI on unemployment among persons with at-risk alcohol use. As part of the randomized controlled 'Trial on proactive alcohol interventions among job-seekers, TOPAS', 1243 18- to 64-year-old job-seekers with at-risk alcohol use were systematically recruited at three job agencies in Germany (2008/09), and randomized to (i) a stage tailored intervention based on the trans-theoretical model of intentional behavior change (ST), (ii) a non-stage tailored intervention based on the theory of planned behavior (NST) and (iii) assessment only (AO). To test the effects of ST and NST on employment status 15 months after baseline, latent growth models were calculated among those initially unemployed (n = 586). In all three groups, unemployment significantly decreased over 15 months (ST: odds ratio, OR = 0.06; 95% confidence interval, CI: 0.01-0.27; NST: OR = 0.04; 95% CI: 0.01-0.18; AO: OR = 0.05; 95% CI: 0.01-0.21). No intervention effects were found on unemployment. Age (P = 0.002), school education (P = 0.001), self-rated health (P = 0.04), the Alcohol Use Disorder Identification Test-Consumption score (P = 0.02) and motivation to change (P = 0.04) significantly affected the development of unemployment over time. After 15 months, no BAI effect on unemployment was found. The mediated effect of BAIs on unemployment could be a longsome process needing longer follow-ups to be detected.
