Effect of the rating source in organizational citizenship behavior: A multitrait-multimethod analysis, The

This study compares the ratings for three dimensions of organizational citizenship behaviour (OCB) provided by managers (self-ratings), their subordinates, and their colleagues (superiors and peers) in the Spanish branch of a multinational food company. Using hierarchical confirmatory factor analysis, we find strong method effects, indicating that ratings from different sources provide different information. A comparison among means shows that, in most cases, subordinate and self-ratings are significantly higher than colleague ratings. We also add to the recent research about the dimensionality of OCB by performing a correlation analysis among OCB dimensions that controls for method effects. Our results show that, when methods are taken into account, correlations among OCB dimensions are not significant.
