RESUMEN
Objective: This study aimed to clarify the assertiveness of psychiatric day care users with schizophrenia.Patients and Methods: We examined 1,179 psychiatric day care center users and 916 psychiatric hospital outpatients with schizophrenia between September 2008 and February 2009 using a questionnaire survey based on the Japanese version of the Rathus Assertiveness Schedule and the Functioning Scale. The questionnaires were distributed and collected by post by the director of each participating facility.Results: Of the 1,179 users (Users) and 916 outpatients (Patients) targeted, 366 (31.0%) and 78 (8.5%) were enrolled in this study. The mean assertiveness score of Users (–7.1 ± 20.2) was significantly higher than that of Patients (–17.3 ± 20.9; P<0.01). Assertiveness scores were higher in Users who performed housework compared with those who did not. High functioning was a background factor that improved assertiveness scores in Users. Additionally, Users could maintain a suitable assertiveness score with support from a psychiatric day care center.Conclusion: This study revealed that Users had a greater ability to self-assert than Patients; this was largely the result of being able to live in society.
RESUMEN
Objective: This study aimed to investigate the validity and reliability of the Japanese version of the Rathus assertiveness schedule (J-RAS) in psychiatric day care users with schizophrenia.Subjects and Methods: We examined 715 psychiatric day care users with schizophrenia by conducting the test twice between September 2007 and February 2008 using a questionnaire-based survey. We examined construct validity and used the internal reliability test, split-half method, and test–retest method to examine reliability. The questionnaires were distributed and collected by post via the director of each facility.Results: Of the 1272 psychiatric day care users, 715 users (56.2%) were enrolled in the study. Seven factors were extracted for construct validity. The cumulative contribution rate of these factors was 49.4% and the internal consistency of 30 items of the J-RAS was α = 0.72. The split-half method revealed a significant correlation between the total scores of the odd- and even-numbered items (r = 0.64, p < 0.01). The test–retest method revealed a significant difference between the total scores of the first and second tests of the 30 items of the J-RAS (r = 0.73, P < 0.01).Conclusion: We confirmed the validity and reliability of the J-RAS in psychiatric day care users with schizophrenia and demonstrated its efficacy in evaluating psychiatric day care users.
