Indirect protective behavioral strategies (PBS) are precautions taken to reduce negative alcohol consequences, while direct PBS involve reducing consumption. Baseline indirect PBS may act as a moderator, while changes in motivation to reduce drinking may be a mediator between the intervention and its effects on negative consequences.
Undergraduate students at sporting events are surveyed on their alcohol use and sexual activity using a smartphone during the game, the day after, and two weeks later. Randomly selected participants will complete a brief intervention or control condition with one-, three-, and six-month follow-ups.
The intervention is expected to decrease alcohol consumption and negative consequences. Motivation to change (MTC) is expected to act as a mediator, increasing following intervention, thus decreasing alcohol consumption and negative consequences. We cannot currently hypothesize on directionality of baseline indirect PBS as a moderator.
The impact of MTC on alcohol consumption and related outcomes reveals the importance of personalized feedback in mobile interventions. The unknown relationship between baseline indirect PBS use and the intervention indicates the importance of future research into its role as a moderator. This is especially important on college campuses which experience a high frequency of alcohol-related consequences.
