Abstract
Objectives
The Patient rejection scale (PRS) has been reported as a valid tool for the assessment of rejecting feelings of family respondents toward schizophrenics who return to live with their families. The aim of this study was to assess the reliability and validity of the Korean-version of PRS (K-PRS).
Methods
A sample of 272 primary caregivers of schizophrenics completed the K-PRS and the data were analyzed for internal consistency and factor structure. Additionally 117 caregivers refilled K-PRS after two weeks for test-retest reliability. To test for validity, Family Questionnaire (FQ), Drug Attitude Inventory-10 (DAI-10) and the Scale to Assess Unawareness of Mental Disorder (SUMD) were administered.
Results
Internal consistency of K-PRS was good (Cronbach' alpha=0.787) and principal component factor analysis revealed the three-factor structure. The K-PRS also showed reasonable test-retest reliability (r=0.795). Convergent validity was examined through correlations between the K-PRS and the FQ-criticism subscale (r=0.78). Divergent validity was examined through correlations between the K-PRS and KDAI-10 (r=-0.02, p=0.001), and between the K-PRS and SUMD-K (r=-0.02, p=0.796).
