Abstract:
OBJECTIVES: The present study was performed to verify the validity and value of 4th revision of Schizophrenia Quality of Life Scale (SQLS-R4) as an assessment tool in a Korean-language version (SQLS-R4K). METHODS: The subjects for present study were 174 patients with a diagnosis of schizophrenia as defined by DSM-IV. The SQLS-R4K was administered together with self-report Korean version of World Health Organization Quality of Life-Brief Scale (WHOQOL-BREF) to assess validity. A subset of respondents also completed the SQLS-R4K for a second time to assess test-retest reliability. To evaluate the relationship SQLS-R4K and clinical characteristics, psychotic symptoms and general functioning were evaluated using the Positive and Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning Scale (GAF) score respectively. RESULTS: All the scales of SQLS-R4K showed good internal consistency reliability. The correlations of items with their scale total revealed that all items were significantly correlated with their own scale score. In test-retest reliability, paired t-tests indicated that responses did not alter significantly between the two assessment. There was moderate correlation between WHOQOL-BREF sub-scores and SQLS-R4K score total. Also relevant correlations between PANSS, current GAF and SQLS-R4K were proved. CONCLUSION: From the results of the testing the reliability and validity of the SQLS-R4K, it is concluded that the SQLS-R4K is a simple and reliable scale for measuring quality of life in schizophrenic patients.
