Objective: To examine the efficacy of dynamic cognitive treatment in rehabilitation of schizophrenic clients. Subjects: Fifty-eight schizophrenic clients that were matched equally into two groups: a study group (n = 29) (treated by Instrumental Enrichment) and a control group (treated with traditional occupational therapy methods). Setting: The subjects were treated in a day rehabilitation centre in the community. Study design: The programme lasted one year, the same schedule was provided for both groups. Subjects were randomly assigned and assessed before and after intervention with the same battery and at a follow-up six months later, work and residence status were evaluated. Main outcome measures: Instruments included: (1) memory and thought processes, measured by a battery of structured tests from the Learning Potential Assessment Device (LPAD), Raven Progressive Matrices and General Aptitude Test Battery (GATB); (2) functional outcomes, instrumental activities of daily living (IADL), measured by a questionnaire; work and residence status; (3) self-concept measured with Fitts questionnaire. Results: Results showed significant differences between the groups on almost all the cognitive tests (MANOVA revealed significant differences between the two groups for both memory and thought process (F(2.52) = 13.75, p < 0.001; and F(1.46) = 7.28, p < 0.001, respectively) as well as in work (χ2 = 14.30, p < 0.001), and residence (χ2 = 3.86, p < 0.05) status. There were no significant differences in IADL questionnaire or the self-concept scale. Conclusions: The successful outcome points to the importance of including long-term cognitive intervention in rehabilitation of schizophrenic clients. This work suggests that the classic view of schizophrenia as a progressive irreversible decline that cannot be altered may be wrong.
