The Adaptation of the High-Performance Work Systems Scale into Turkish: A Validity and Reliability Study

Abstract

INTRODUCTION: This methodological study was performed to determine whether the Turkish version of the High Performance Work Systems Scale developed by Zacharatos in 2001 is a valid and reliable tool for nurses in Turkey. METHODS: The study was conducted with 450 nurses who are working in five hospitals in Istanbul between November 2016 and January 2017. The study data were collected using the "Descriptive Characteristics Form", and "High Performance Work Systems Scale" consisting of 51 items. RESULTS: The scale was translated from English into Turkish considering international scale adaptation standards. The content validity index (CVI) of the scale was 0.97. Nine items whose correlation coefficient was less than 0.25 were excluded from the scale. The stability of the scale over time was tested with 20 nurses twice at a 15-day interval. There was no significant difference between the two measurements. In the exploratory factor analysis, five items with a factor loading of <0.40 were removed and the remaining items were included in six sub-dimensions. In the confirmatory factor analysis, the path coefficients of the items with their own dimension ranged between 0.31 and 0.84. The goodness of fit of the model determined in the confirmatory factor analysis was at an acceptable level. The Cronbach's alpha reliability coefficient was 0.88 for the overall scale and ranged from 0.56 to 0.85 for the sub-dimensions. DISCUSSION AND CONCLUSION: The results of this study indicated that the scale is a valid and reliable tool and thus can be administered to nurses in Turkey. Nurse Managers and researchers can benefit from this scale to assess the institutional performance.
