Young Adults' Daily Participation Scale: A measure of objective and subjective participation

Participation, or how one engages in daily life activities, greatly affects wellbeing. The activities in one's routine change over the lifespan, in accordance with one's developmental phase. Existing assessments of participation have limitations, like not considering young adults' concerns or only focussing on certain aspects of participation. By focussing on both the objective-observable and subjective-experiential aspects of participation, the Young Adults' Daily Participation Scale (YADAPS) strives to be a comprehensive assessment tool designed specifically for reflecting activities relevant in young adulthood. This manuscript provides preliminary validity and reliability for the YADAPS, a new questionnaire that assesses objective and subjective aspects of participation in activities relevant for individuals in young adulthood. Furthermore, the questionnaire is able to distinguish between young adults with and without participation difficulties; therefore, it is suitable for research and clinical use.
