Reliability and Validity of Subjective Well-Being Under Neuroleptics Scale-Short Form-Turkish Version

Abstract

Objective: The Subjective Well-Being Under Neuroleptics Scale (SWNS) is a self-reported measure that evaluates the state of well-being of schizophrenis patients using antipsychotic drugs independently of psychotic symptoms. This study was intended to establish the validity and reliability of the Turkish version of the scale. Methods: The Cronbach alpha coefficient was calculated for reliability analysis of the scale, which was translated into Turkish and applied to 103 schizophrenia patients. The criterion validity was examined by correlation with reference scales (Turkish Version of the Functional Remission of General Schizophrenia, The Short Form of the World Health Organization Quality of Life) concurrently in use. The construct validity of the scale was assured using both exploratory and confirmatory factor analyses. Findings: The Turkish version of the scale was found to have a high reliability co-efficient (0.881). In terms of total scores, the correlation with other scales is mediumgood. However, the results of the Turkish version factor analysis were incompatible with the sub-dimensions of the original scale. Conclusions: Our findings show that the Turkish version of this scale is a valid and reliable tool in the evaluation of states of subjective well-being of schizophrenic patients using antipsychotic drugs. On the other hand, we recommend that studies to be conducted in Turkey use only the scale total score.
