Abstract:
Objective • To investigate the reliability and validity of Chinese version of Working Alliance Inventory-Short Form Revised (WAI-SR) in the hospitalized schizophrenics. Methods • A sample of 124 inpatient schizophrenics who were diagnosed according to International Classification of Diseases 10th Revision in Shanghai Mental Health Center and collected by convenience sampling, were interviewed by questionnaire. Item analysis, internal consistency, construct validity and criterion validity were tested using total sample. Patient-Doctor Relationship Questionnaire-15 (PDRQ-15) and Chinese version of Wake Forest Physician Trust Scale (WFPTS) were used as criteria to test criterion validity. Results • Exploratory factor analysis extracted two dimensions labeled "goal and task" and "affective bond", and the cumulative variance contribution rate was 63.99%. Confirmatory factor analysis showed that the two-factor model had higher adjusted goodness of fit index. The scores of scale and its two dimensions exhibited positive correlations with PDRQ-15 and WFPTS (r=0.324-0.726, P<0.01). The internal consistency of the scale (Cronbach's α coefficient) was 0.864, and split-half reliability was 0.919.Conclusion • The Chinese version of WAI-SR is acceptable in reliability and validity and can be recommended for alliance assessment in the inpatients with schizophrenia.
