Organisational and professional commitments: The influence in nurses' organisational citizenship behaviours

The study shows how organisational and professional commitment is related with nurses' organisational citizenship behaviours. Data from a sample of 420 nurses working in two hospitals - the Hospital of St. Marcos, Braga and the Hospital Centre of Alto Ave, Guimarães and Fafe units were collected. The main findings are as follows: (a) organisational commitment and professional commitment contribute to the explanation of nurses' organisational citizenship behaviours, (b) affective organisational commitment, continuance organisational commitment - personal sacrifice, affective professional commitment and continuance professional commitment explain 28.6% of variance of organisational citizenship behaviours.
