Self-Relevant Appeals to Engage in Self-Monitoring of Alcohol Use: A Microrandomized Trial
Link to full item
This study investigated the utility of two types of digital prompts (reminders) to encourage young adults to self-monitor their alcohol use. Participants were 591 college students enrolled in an 8-week intervention study involving biweekly digital self-monitoring of their alcohol use. At baseline, participants selected an item they would like to purchase for themselves, as well as a charitable organization to which they would like to donate. Then, biweekly, participants were microrandomized to a prompt highlighting the opportunity to either (a) win their preferred item (self-interest prompt); or (b) donate to their preferred charity (prosocial prompt). Following self-monitoring completion, participants allocated reward points toward lottery drawings for their item or charity. The self-interest prompt was significantly more effective in promoting self-monitoring at the beginning of the study, whereas the prosocial prompt was significantly more effective at the end of the 8 weeks. Further, the prosocial prompt was significantly more effective among participants who previously had allocated all their reward points to lottery drawings for their preferred item.
