Rego, A. & Cunha, M. P. (in press). Organisational citizenship behaviours and effectiveness: An empirical study in two small insurance companies. Service Industries Journal.
An instrument previously developed and validated by Rego (1999, 2000) for measuring OCB at the individual level of analysis was used for measuring citizenship behaviours at the aggregated level of analysis. Five dimensions were measured: interpersonal harmony, conscientiousness, personal initiative, identification with the organisation, and helping and courtesy toward customers.
