Abstract
People spend a significant part of their lives in their workplaces, and this causes them to wear out physically, mentally, and psychologically. The primary purpose of this study is to develop the Employee Attrition Scale (ESS) to determine the employees' mental and psychological attrition perceptions. In the process of developing the scale, firstly, the "candidate scale" item pool was created based on the mental and psychological health conditions of the World Health Organization, suitable for mental and psychological wear and tear. Then, expert opinion was sought for the content validity of the scale. After the content validity study, the pilot study of the draft scale was carried out with 145 employees working in manufacturing enterprises. The data collected with the candidate scale were first analyzed with Exploratory Factor Analysis (EFA). As a result of the Exploratory Factor Analysis, the four-factor structure of the scale was determined. The main application of the scale was carried out with the participation of 334 employees selected by the stratified sampling method by expanding the same sample. In the main application, the validity of the Employee Attrition Scale was determined by Confirmatory Factor Analysis (CFA), and the Cronbach alpha coefficient determined its reliability. Confirmatory Factor Analysis results confirmed the structure of the four-dimensional Employee Attrition Scale developed during the pilot study. As a result of the validity and reliability analysis, it was concluded that the developed scale is a reliable and valid data collection tool.
