A Bigger Piece of the Pie : The Relative Importance of Affiliative and Change-Oriented Citizenship and Task Performance in Predicting Overall Job Performance

We examine the extent to which both in-role (task performance) and extra-role dimensions of performance (organizational citizenship behaviors) account for variance in ratings of overall job performance by utilizing currently available meta-analytic estimates. Relative weight analysis results show that overall performance is determined more by three OCB forms in combination (RW = .34; %RW = 72.9%) than by task performance (RW = .12; %RW = 27.1%). Among the OCB forms, the relative weight of OCB-O (RW = .17; %RW = 36.9%) is greater than those of OCB-I (RW = .11; %RW = .22.9%) and OCB-CH (RW = .06; %RW = 13.1%). Consistent with the results from a relative weight analysis, results from a series of multiple regression analyses also show that the incremental contribution (ΔR2) of each performance dimension above and beyond the other performance dimensions is the highest for OCB-O (.056), followed by those of task performance (.041), OCB-CH (.007), and OCB-I (.003). We discuss the theoretical and practical implications of these findings along with study limitations and future research directions
