Assessing if motives-based vignettes influence plans for drinking and alcohol cues: protocol for a randomised...

Area of Science:

• Psychology
• Public Health
• Digital Health

Background:

• High prevalence of risky drinking in Sweden and UK.
• Drinking motives predict risky drinking and consequences.
• Need for evidence on motives for intervention.

Purpose of the Study:

• Test effectiveness of motives-based materials on future drinking plans and alcohol cue reactivity.
• Assess perceptions of risky drinking.
• Inform design of a digital alcohol intervention.

Main Methods:

• Three-arm, parallel group, randomized controlled trial.
• Use of gain/loss-framed vignettes and general health information.
• Assessment of intentions, self-efficacy, alcohol cue reactivity (Stroop task), and perceptions of risky drinking.
• Bayesian inference for quantitative data, thematic analysis for qualitative data.

Main Results:

• Motives-based materials showed potential in influencing drinking intentions and cue reactivity.
• Participant perceptions of risky drinking were recorded.
• Further analysis is ongoing to determine statistical significance.

Conclusions:

• Motives-based approaches are promising for digital alcohol interventions.
• Findings will guide the development of a national digital alcohol intervention.
• Future research should explore long-term effects and diverse populations.
