Exploring two subdimensions of participation, involvement and engagement: A scoping review.

This scoping review points in a direction that the two subdimensions of participation need to be separated, with involvement being a more stable internal state of interest towards an activity, and engagement referring to the specific behaviour, emotions, and thoughts meanwhile participating in a specific setting. Clear definition of concepts will enhance the development of measures to evaluate rehabilitation interventions in the field of occupational therapy and related fields.
