In the extant literature, it is possible to find many studies focusing on antecedents of OCB, both cognitive factors and affective factors. However, previous research made limited contribution to the literature, since it did not focus on an integrative model covering both cognitive and affective factors. In this study it was aimed to search an integrative relationship among OCB, cognitive factors and affective factors. Following previous literature, justice perceptions and mood states of employees were taken as cognitive and affective factors respectively. Main purpose of this study is to see the individual influence of justice perceptions and positive mood states on OCB, while also testing a possible mediating role of justice perceptions between positive mood states and OCB. A Turkish public bank was chosen for conducting the survey. After missing value and outlier analysis 210 participants were left. Employees of the bank were asked to rate the items measuring OCB, justice perceptions and mood states. Hierarchical regression analyses were used to test suggested propositions. In line with literature, both aggregate variable of justice perceptions and positive mood states were found to be positively associated with OCB. However, justice perceptions‟ mediating role between employee positive mood states and OCB could not be supported. The exploratory analyses held in this study, showed existence of a different relationship where positive mood states mediate the relationship between justice perceptions and OCB. This issue should be raised in future studies again and two models should be compared in more detail.
