In this model, participation is the result of the interaction between individual characteristics such as age, gender, disabilities, as well as personality disorders and the environmental factors of the place of residence. Participation is conceptualized through the concept of life habits referring to daily activities and social roles; it is valued by the individual coupled with the cultural and social environment. In this model, social roles are not in their usual sense and they are not limited to roles such as a mother, student or worker; rather, they involve participation in financial or civil responsibilities, interpersonal communication, social life, employment,education, and entertainment.
