Despite the resurgence of leadership research, few investigations have exam
ined the association between leadership behaviors and organizational perfor
mance in the social work field. The purpose of this study was to evaluate e
mpirically a model that delineates two types of leadership processes, trans
formational and transactional leadership, within social work practice as me
asured by the Multifactor Leadership Questionnaire. The model was tested wi
th a sample of 187 clinical social workers employed in hospitals. Results i
ndicated that all five transformational factors and one transactional facto
r were significantly correlated with leader outcomes of effectiveness, sati
sfaction, and extra effort. Implications for social work practice are provi
ded.
