Temporary abstinence during Dry January: predictors of success; impact on well-being and self-efficacy

Abstract

Background: Temporary alcohol abstinence conveys physiological benefits. Less well-known are its effects on well-being and general self-efficacy (GSE), and how use of support during alcohol abstinence challenges affects success rates.

Methods: In this study, 4232 adults participating in ‘Dry January’ completed a baseline questionnaire and a 1-month follow-up questionnaire. Key follow-up variables related to whether respondents completed the abstinence challenge, their use of support provided by Dry January, and changes in well-being and GSE. Analyses also examined whether well-being and GSE explained variance in the likelihood of completing Dry January not accounted for by other variables known to be associated with successful attempts at Dry January.

Results: Participation in Dry January was associated with increases in well-being and GSE among all respondents: these changes were larger among people who successfully completed the challenge. In multivariate analysis, greater use of email support was a significant independent correlate of completing Dry January.

Conclusions: This paper adds to growing evidence that support provided through organised abstinence challenges is associated with changes in beliefs linked to harmful drinking. However, there is a need for further research to help us to understand what forms of support are most effective for different drinkers.
