Official Title: Exploring Whether Experimentally Manipulated Self-affirmation Promotes Reduced Alcohol Consumption in Response to Narrative Health Information
Brief Summary: This study tests the effects of a self-affirmation manipulation on (i) acceptance of a health message detailing the risks of alcohol consumption, (ii) engagement with the health message and (iii) alcohol consumption at 7-day follow-up. Half of the participants complete a self-affirmation manipulation, where they reflect on their most important values, whereas the other half complete a control equivalent, where they reflect on their least important values. Immediately post-intervention, all participants then receive information about the risks of alcohol consumption and complete measures of message acceptance and engagement with the materials. Seven days after intervention, participants self-report their alcohol consumption in the previous 7 days.
Detailed Summary:
Sponsor: University of Sussex
Current Primary Outcome: Alcohol consumption 7 days after intervention [ Time Frame: 7 days after intervention ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Effect of intervention on acceptance of health information [ Time Frame: Immediately after intervention ]Measures to assess whether the intervention affected the extent to which people accepted information about the risks of alcohol consumption were taken immediately after the intervention via self-report items. Acceptance items included personal relevance, negative affect, attitudes, anticipated regret and intentions. Responses to items were given on 7-point scales with relevant anchors (e.g. strongly disagree [1] to strongly agree [7]). A mean score was calculated for each participant on each measure, with higher scores indicating greater levels of that construct.
- Effect of intervention on engagement with health information [ Time Frame: Immediately after intervention ]Measures to assess whether the intervention affected the extent to which people engaged with the information were taken immediately after the intervention via self-report items. Engagement items included perspective taking, attention, emotion and visualization. Responses to items were given on 7-point scales with relevant anchors (e.g. strongly disagree [1] to strongly agree [7]). A mean score was calculated for each participant on each measure, with higher scores indicating greater levels of that construct.
Original Secondary Outcome: Same as current
