Abstract
This study aimed to develop and evaluate the effectiveness of the illness management model for patients with schizophrenia to reenter community by conducting a randomized controlled trial. Ninety-seven patients with schizophrenia were randomly assigned to the illness management model or the treatment as usual alone. Multiple outcomes were measured before the intervention, after completion of intervention, and at one-month after the intervention. Data analyses by using SPSS for Windows version 13.0 were conducted on an intention-to-treat basis. Differences of the pre- and posttest scores and demographic data between the two groups were assessed with independent t test or chi-square test, as appropriate. A linear mixed model of time-related repeated measurement was performed for the five dependent variables to determinate whether treatment was associated with the interactive effects postulated (group × time). The level of significance for the statistical tests was set at .05.
Ninety percent of the patients completed the trial. More than sixty percent of the patients were men, and about two-thirds were unmarried, unemployed, and educated with 12 years. 95.9 percent of the patients were diagnosed as schizophrenia. The patients’ mean age was 35.26± 9.51 years and mean illness years were 11.52 ± 8.47 years. There was no difference on each demographic variable between two groups. Patients who received illness management model performed significantly greater and/or more enduring improvements after intervention completion and at one-month follow-up. The linear mixed model showed that the illness management model was associated with consistently greater improvements in illness knowledge, insight, and drug attitude over the follow-up period compared with the treatment as usual.
The illness management model for patients with schizophrenia reenter to community provided by psychiatric nurses was effective to equip patients’ skills on illness management, and improve their illness knowledge, drug attitude, and insight lasted over the follow-up period. Future studies could further examine the effectiveness of different target populations, other interveners and the lasting effect of extended follow-up period, and adopt more sensitive measures.
