摘要:The success of an organization is influenced by employees who not only perform their job, but also contribute their time and energy to provide assistance beside the formal obligations to the organization. This behavior is referred to as organizational citizenship behavior. This study was conducted to analyze the validity of the Organizational Citizenship Behavior Scale. Therefore, there were two main objectives in this study, namely to examine the construct validity of the Organizational Citizenship Behavior Scale using confirmatory factor analysis (CFA) and to assess the reliability of the scale. Organizational citizenship behavior was measured using three dimensions and they were helping behavior, civic virtue and sportsmanship. The study was conducted on 11 religious schools located in North, East, South, Middle and West of South Sulawesi, Indonesia. The schools consisted of 339 teachers. However, after examination of normality data, only 208 respondents were used as samples. The results of the study showed that the hypothesized model did not have a good fit to the data with Chi Square =190.168, p < 0.0001, CFI = 0.89, GFI = 0.92, TLI = 0.87, RMSEA = 0.078. Thus, this model has to be revised. The results of the revised model showed a better fit with Chi Square =118.335, p < 0.0001, CFI = 0.93, GFI = 0.92, TLI = 0.90, RMSEA = 0.07. The findings were discussed based on the suitability of the Organizational Citizenship Behavior Scale as a valid measure within Indonesian context.
