“…This means that changes in the supports available to people that reduce their exposure to stress or facilitate their learning of coping, social, or other skills can have a direct effect on the severity of their symptoms and the likelihood of symptom relapses. For example, engaging a person with psychotic symptoms in some type of structured activity (e.g., work, recreational activity) reduces the severity of those symptoms (Corrigan, Liberman, & Wong, 1993; Rosen, Sussman, Mueser, Lyons, & Davis, 1981; Wong et al, 1987). The dynamic interplay between the environment, the person, and the course of symptoms and relapses raises further questions about the validity of distinguishing between treatment and rehabilitation; symptoms and functioning are intertwined, each affecting the other.…”
