Abstract

Objectives:The purpose of this study was to develop the Korean version of the psychiatric patients’ experience of stigma (PPES) among the patients with schizophrenia.
Methods:The PPES was administered to 178 schizophrenic patients and 51 depressive patients for examining the reliability and validity. All patients were enrolled at the outpatient psychiatric clinic of university hospital and the status of psychopathology were stable. The PPES was modified from the original version for this study. The original version has two sections covering nine stigma and 12 discrimination questions. Among discrimination items, two items concerning health insurance were deleted because health insurance environment is quite different between Korea and U.S.A. Additionally, the term “consumer” was supplemented with the term “persons with mental illness”. And each item on the PPES also has “Does Not Apply” option.
Results:
Resultsof this study confirmed sound psychometric properties of the PPES. The test-retest reliability and the internal consistency of PPES were 0.84 and 0.78. Evidence for discriminant validity of PPES came from the results that the total PPES scores of schizophrenic patients were significantly higher than those of depressive patients. Factor analysis were performed and five factors accounting for 69.9% of the variance were extracted.
Conclusion:The Korean version of PPES was found to be a valid and reliable instrument which can be used to evaluate the degree of experience of stigma and discrimination in the patients with schizophrenia. (Korean J Schizophr Res 2010;13:34-41)
