The Leisure Ability Model is one of the oldest, most widely used, and most often critiqued therapeutic recreation practice models. It is based on the concepts of internal locus of control, intrinsic motivation, personal causality, freedom of choice, and flow. The Leisure Ability Model uses these ideas as the basis for three components of service: treatment, leisure education, and recreation participation. These three areas of service supply the content for creating, developing, implementing, and evaluating therapeutic recreation programs that are based on client need. The overall intended outcome of therapeutic recreation services, as defined by the Leisure Ability Model, is a satisfying, independent, and freely chosen leisure lifestyle. Included in this review are noted strengths, weaknesses, and directions for future development.
