Prospective associations between insomnia symptoms and alcohol use problems among former and current military service personnel.
Despite evidence that insomnia symptoms exacerbate alcohol use disorder symptoms, there is a dearth of prospective research testing bidirectional associations between these variables. Furthermore, no studies have prospectively examined these associations among military personnel, a vulnerable population for sleep- and alcohol-related problems. Thus, the current study examined whether insomnia symptoms prospectively predicted increased alcohol use disorder symptoms among a sample of military service members and veterans over a 6-month follow-up period, as well as whether alcohol use disorder symptoms led to increases in insomnia.
Hypotheses were tested among a sample of 274 current and past military service members who participated in a baseline and 6-month assessment using self-report measures.
Path analyses revealed that insomnia symptoms significantly prospectively predicted increased month-6 heavy drinking and alcohol-related problems, but not days drinking or being bothered by drinking. None of the alcohol variables significantly predicted insomnia.
Results support a model in which insomnia symptoms exacerbate alcohol use disorder symptoms, specifically heavy drinking and alcohol-related problems. Future research should seek to examine these findings in diverse populations and test potential mechanisms and clinical implications of these results.
