Objective: The purpose of this study was to develop a Participation Assessment measure for home visit Rehabilitation (PAR) for elderly.Methods: For the development of the PAR, the opinions of rehabilitation professionals were collected using the Delphi method according to the relevant literature, and the questionnaire items were organized. Subsequently, a survey of elderly home-visit rehabilitation users was conducted using the provisional version of the PAR. Content validity was verified by exploratory factor analysis, and the structure and items were selected. Correlations with the level of nursing care were investigated.Results: The relevant literature indicated 779 scale items for 34 scales, and the PAR provisional version had 27 items after three Delphi methods by 17 therapists. The survey was completed by 203 subjects (82.3±8.1 years) from 9 facilities. Exploratory factor analysis resulted in a four-factor structure with maximum likelihood Promax rotation. Finally, a 19-item 76-point PAR was developed and negatively correlated (r = −0.492) with the level of nursing care.Conclusion: The PAR was developed as a validated participation rating scale for home visit rehabilitation users, including those with dementia and those who require severe nursing care, evaluated by healthcare professionals.
