A text message @entity167 intervention for young adult @entity341 XXXX : a randomized clinical trial.

@entity1 @entity341 @entity851 @entity167
STUDY OBJECTIVE: Opportunistic brief in- @entity1 @entity341 ( @entity341 ) interventions can be effective at reducing hazardous @entity167 use in young adult drinkers, but require resources frequently unavailable. Mobile telephone text messaging ( @entity851 [ @entity851 ]) could sustainably deliver behavioral support to young adult @entity1 , but efficacy remains unknown. We report 3-month outcome data of a randomized controlled trial testing a novel @entity851 -delivered intervention in hazardous-drinking young adults. METHODS: We randomized 765 young adult @entity341 @entity1 who screened positive for past hazardous @entity167 use to one of 3 groups: @entity851 assessments+feedback (SA+F) intervention who were asked to respond to drinking-related queries and received real-time feedback through @entity851 each Thursday and Sunday for 12 weeks (n=384), @entity851 assessments (SA) who were asked to respond to @entity167 consumption queries each Sunday but did not receive any feedback (N=196), and a control group who did not participate in any @entity851 (n=185). Primary outcomes were self-reported number of binge drinking days and number of drinks per drinking day in the past 30 days, collected by Web-based timeline follow-back method and analyzed with regression models. Secondary outcomes were the proportion of @entity1 with weekend binge episodes and most drinks consumed per drinking occasion during 12 weekends, collected by @entity851 . RESULTS: With Web-based data, there were decreases in the number of self-reported binge drinking days from baseline to 3 months in the SA+F group (-0.51 [95% confidence interval {CI} -0.10 to -0.95]), whereas there were increases in the SA group (0.90 [95% CI 0.23 to 1.6]) and the control group (0.41 [95% CI -0.20 to 1.0]). There were also decreases in the number of self-reported drinks per drinking day from baseline to 3 months in the SA+F group (-0.31 [95% CI -0.07 to -0.55]), whereas there were increases in the SA group (0.10 [95% CI -0.27 to 0.47]) and the control group (0.39 [95% CI 0.06 to 0.72]). With @entity851 data, there was a lower mean proportion of SA+F @entity1 reporting a weekend binge during 12 weeks (30.5% [95% CI 25% to 36%) compared with the SA @entity1 (47.7% [95% CI 40% to 56%]). There was also a lower mean drinks consumed per weekend during 12 weeks in the SA+F group (3.2 [95% CI 2.6 to 3.7]) compared to the SA group (4.8 [95% CI 4.0 to 5.6]). CONCLUSION: A text message intervention can produce small reductions in self-reported binge drinking and the number of drinks consumed per drinking day in hazardous-drinking young adults after @entity341 discharge.
