Social norm perceptions predict citizenship behaviors

Purpose – The purpose of this paper is to examine the extent to which perceptions of injunctive and descriptive norms for workplace organizational citizenship behaviors (OCBs) affect an individual’s frequency of performing such behaviors. The study also explores whether the effects of norm perceptions are moderated by the individual’s need to belong (NTB) to social groups. Design/methodology/approach – Hierarchical regression analysis was used to analyze data from 77 employed MBA students. Perceptions of OCB norms and NTB were assessed with an initial survey. Eight weeks later, a second survey assessed the individual frequency of OCBs. Findings – Descriptive norms, injunctive norms, and NTB independently predicted OCB frequency. Additionally, NTB moderated the effects of injunctive norm perceptions. The injunctive norm was particularly influential for employees high in NTB. Research limitations/implications – Limitations of this study include its cross-sectional nature and the possibility of common method bias. Practical implications – Study results indicate that managers can encourage OCBs by drawing attention to the prevalence of OCBs in the workplace (descriptive norm) and by showing approval of OCBs (injunctive norm). Hiring those with high NTB will also increase OCBs and enhance the effects of any effort on management’s part to signify approval of OCBs. OCBs can also be encouraged through new employee orientation and training that emphasizes the descriptive and injunctive norms for OCBs. Originality/value – This is the first study to demonstrate social norms and NTB as predictors of workplace OCBs. This study also provides the first evidence that the effects of injunctive norms are moderated by NTB.
