The employee extra-role proactive behaviors are among the behaviors that can have a great impact on the success of the organization. Therefore, studying the factors affecting the occurrence of these behaviors is very important. This study aimed to investigate the effect of psychological capital on proactive extra-role behaviors with an emphasis on the mediating role of organizational social capital. This research was a descriptive and correlation survey in terms of methodology and an applied survey in terms of purpose. The statistical population of the study consisted of the staff of Day Insurance Headquarters, out of whom a sample of 205 employees was selected through convenience sampling. The required data was collected by a questionnaire and analyzed based on the structural equation modeling using the partial least squares method. The findings showed that psychological capital and organizational social capital have a positive and significant effect on proactive extra-role behaviors including helping behaviors and employees' voice. Furthermore, the mediating role of organizational social capital in the effect of psychological capital on employees’ extra-role behaviors was confirmed as well.
