This study investigates the relationship between hospital quality improvement (QI) team success and changes in empowerment, 'organizational commitment, organizational citizenship behaviour' (OCB) and job behaviour related to QI. Data were collected from administrative staff, healthcare professionals and support staff from four community hospitals. The study involved a field investigation with two data collection points. Structured questionnaires and interviews with hospital management were used to collect data on the study variables. High scores were observed for organizational commitment, OCB and job behaviour related to QI when individuals identified with teams that were successful. Low scores were observed when individuals identified with teams that were unsuccessful. Empowerment was positively related to job behaviour associated with QI. It is concluded that participation on QI teams can lead to organizational learning, resulting in the inculcation of positive 'extra-role' and 'in-role' job behaviour.
