Abstract

Background: Alcohol use is a gendered behavior and motherhood is a life stage which may influence drinking motives. However, there are no drinking motive scales uniquely tailored to maternal populations. This work developed a new maternal drinking motives scale (M-DMS) and determined associations between the M-DMS and alcohol-related behavior. Methods: An online observational survey (n = 534) and online test–retest survey (n = 164) were conducted with adult, UK mothers. From the observational study, data on drinking motives was extracted to determine M-DMS items and factor loading. This was split into two data sets for exploratory and confirmatory factor analyses. Alcohol Use Disorders Identification Test (AUDIT) and Timeline Follow back data, taken from both surveys, were combined to determine the M-DMS’s predictive validity. Results: Following a parallel analysis and exploratory factor analysis, a two-factor model (positive reinforcement motives, negative reinforcement motives) was deemed the best fit. Probability functional analysis identified items with problematic responses. These were removed before confirmatory factor analysis (on the second dataset) demonstrated a good fit for the two-factor model. All factor loadings were significant and positive (βs > 0.56). Reliability of the two subscales was excellent: negative reinforcement (ωT = 0.95), positive reinforcement (ωT = 0.89). Test–retest reliability was good for both negative (ICC = 0.84, 95%CI = 0.80–0.88) and positive (ICC = 0.77, 95% CI = 0.71–0.82) subscales. Both subscales predicted AUDIT and quantity of alcohol consumption (ps < 0.001). Conclusion: The first tailored Maternal Drinking Motives Scale (M-DMS) provides a more valid research tool for assessing psychological mechanisms of alcohol use in mothers.
