Abstract
Objective:
To compare the therapeutic effects of subject-chosen and therapist-chosen activities in occupational therapy for inpatients with chronic schizophrenia.
Design:
Prospective comparative study.
Setting:
A psychiatric hospital in Japan.
Subjects:
Fifty-nine patients with chronic schizophrenia who had been hospitalized for many years.
Interventions:
The subjects received six-months occupational therapy, participating in either activities of their choice (subject-chosen activity group, n = 30) or activities chosen by occupational therapists based on treatment recommendations and patient consent (therapist-chosen activity group, n = 29).
Main measures:
The Positive and Negative Syndrome Scale and the Global Assessment of Functioning (GAF) Scale were used to evaluate psychiatric symptoms and psychosocial function, respectively.
Results:
After six-months occupational therapy, suspiciousness and hostility scores of the positive scale and preoccupation scores of the general psychopathology scale significantly improved in the subject-chosen activity group compared with the therapist-chosen activity group, with 2(2) (median (interquartile range)) and 3(1.25), 2(1) and 2.5(1), and 2(1) and 3(1), respectively. There were no significant differences in psychosocial functions between the two groups. In within-group comparisons before and after occupational therapy, suspiciousness scores of the positive scale, preoccupation scores of the general psychopathology scale, and psychosocial function significantly improved only in the subject-chosen activity group, with 3(1) to 2(2), 3(1) to 2(1), and 40(9) to 40(16) respectively, but not in the therapist-chosen activity group.
Conclusions:
The results suggested that the subject-chosen activities in occupational therapy could improve the psychiatric symptoms, suspiciousness, and preoccupation of the inpatients with chronic schizophrenia.
