Employee sustainable performance (ESP) scale: Turkish validity-reliability study

Abstract

Objective: Employee sustainable performance is an ideal state of employees to work and be productive throughout their lives. The goal is to meet the future working needs of the organization. In this study, it was aimed to make its validity and reliability of the Employee Sustainable Performance (ESP) scale by adapting it to Turkish. Methods: The Employee Sustainable Performance (ESP) Scale developed by Ji et al. was used to reach the data of the study. The original scale has 10 items and one factor. For the validity and reliability analyzes of the study, a total of 316 health workers working in a training and research hospital operating in Ankara were included in the sample. The questionnaire used was applied face to face to health workers. Within the scope of the study, first of all, language validity was ensured. Then, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed for construct validity. Finally, internal consistency test was performed for reliability analysis. Results: As a result of the analysis, the Turkish language validity of the original scale in English was ensured. Afterwards, Then, EFA was performed and the Kaiser-Meyer-Olkin value was found to be within the normal range with 0.94 and the Barlett Test of Sphericity was significant (X2= 3039.130, df = 45, p<0.05). In addition, according to the results of EFA performed using principal component analysis method, a total of 10 expressions in the ESP scale were grouped under a single factor. This single factor explains 71.81% of the total variance. Then, CFA was performed and it was determined that all of the fit indices were within acceptable limits. Thus, it has been demonstrated that the ESP scale is valid. Finally, Cronbach’s alpha coefficient was calculated as 0.956 for the reliability of the scale, and the scale was found to be highly reliable. Conclusion: Human resources play an important role in determining sustainable strategies in organizations. It can be said that the realization of sustainable performance will be an important factor in increasing the quality and motivation of the employees. In this context, the sustainable performance of the employees will be measured and managed appropriately by using the valid and reliable ESP scale.
