Objectives: A limitation of adult day service (ADS) research is that there remains little understanding of how these community-based long-term care programs operate to benefit clients or family caregivers (i.e. the process of ADS use). The purpose of this study was to validate the ‘ADS Process and Use Measures’ (APUM) which were developed to assess such mechanisms. Method: Participant observation and semi-structured interviews in two ADS settings resulted in qualitative data to inform a conceptual model, subscales, and Likert-scale items.
