Design, efficacy, and methodology considerations for brief interventions: Intervention delivery and incentives

This research evaluated the effects of two methodological factors (i.e., delivery modality and incentives) on attrition, data quality, depth of processing, and perceived value of a personalized normative feedback (PNF) intervention targeting drinking reduction in college students. We expected in lab (vs. remote) participation would be associated with lower attrition, better data quality, and greater depth of processing and intervention value. We further expected that being offered an incentive (vs. not) would be associated with less attrition and better data quality, but lower depth of processing and intervention value. Finally, we expected depth of processing and intervention value to be related to reductions in drinking among PNF participants. Heavy drinking college students (
