%X AIMS: To test the effectiveness of a theoretically based text-message intervention to reduce binge drinking among socially disadvantaged men. <br><br>DESIGN: A multi-centre parallel group, pragmatic, individually randomized controlled trial. SETTING: Community-based study conducted in four regions of Scotland. PARTICIPANTS: A total of 825 men aged 25-44 years recruited from socially disadvantaged areas who had two or more episodes of binge drinking (> 8 UK units on a single occasion) in the preceding 28 days: 411 men were randomized to the intervention and 414 to the control. INTERVENTION AND COMPARATOR: A series of 112 interactive text messages was delivered by mobile phone during a 12-week period. The intervention was structured around the Health Action Process Approach, a comprehensive model which allows integration of a range of evidence-based behaviour change techniques. The control group received 89 texts on general health, with no mention of alcohol or use of behaviour change techniques. MEASUREMENTS: The primary outcome measure was the proportion of men consuming > 8 units on three or more occasions (in the previous 28 days) at 12 months post-intervention. <br><br>FINDINGS: The proportion of men consuming > 8 units on three or more occasions (in the previous 28 days) was 41.5% in the intervention group and 47.8% in the control group. Formal analysis showed that there was no evidence that the intervention was effective [odds ratio (OR) = 0.79, 95% confidence interval (CI) = 0.57-1.08; absolute reduction 5.7%, 95% CI = -13.3 to 1.9]. The Bayes factor for this outcome was 1.3, confirming that the results were inconclusive. The retention was high and similar in intervention (84.9%) and control (86.5%) groups. Most men in the intervention group engaged with the text messages: almost all (92%) replied to text messages and 67% replied more than 10 times. <br><br>CONCLUSIONS: A theoretically based text-messaging intervention aimed at reducing binge drinking in disadvantaged men was not found to reduce prevalence of binge drinking at 12-month follow-up.<br><br>© 2018 The Authors.
