The study aimed to assess how methodological factors—specifically, incentive type (fixed payment, fixed payment with personalized feedback, or incremental payment) and retrospective time frame (since the last beep, or in the last 30/60/90 minutes)—affect participant experience and behavior during a 14-day experience sampling method (ESM) protocol.<br> <br> The dataset includes data from 192 university students who completed a baseline session, a 14-day ESM period, and a follow-up assessment. During the ESM period, participants received nine semi-random notifications per day (between 9:00 and 22:30) and completed brief questionnaires assessing, for example, momentary affect (positive and negative) and context. Baseline and follow-up measures include, for example, demographic information, information about personality and mental health topics, as well as questionnaires pertaining to the methodological aspects of the study. The dataset also includes response times for the ESM questionnaires.<br> <br> For more information about the study/dataset, we refer the reader to the (pre)registrations of the project: <i>https://osf.io/t6wkc/?view_only=755b5b70760344b8860ed7d2f2c70de3</i> & <i>https://osf.io/smqb8/overview?view_only=6d86553d7afa42829f31c89a6c0e9191</i>Leuven, BelgiumFonds Wetenschappelijk Onderzoek (FWO)G049023N
