This study focuses on the role of supervisor-subordinate communication and leadership style on organisational
commitment of nursing staff in the selected hospital. Meyer and Allen’s instrument for multidimensional
organizational commitment was utilized in this research. Leader Behavior Description Questionnaire was
adapted from Stogdill’s” (LBDQ-XII) form 12 and the items related to supervisor- subordinate communication
were derived from two different researches by Heald, Girton and Kazanskya. The structured questionnaire was
completed by 134 nursing staff of a major complex hospital in Tehran, Iran. In the demographic data, the
majority of the respondent were 20 -30 years old female, had more than 10 years tenure and a Bachelor Degree.
Overall, T-test analysis showed significant differences in type I and type II leader’s consideration regarding level
of affective and continuance commitment. Regression analysis indicated a significant contribution of
communication exchange in affective commitment through type I and type II leader’s consideration, whereas
mutual communication showed a significant contribution in affective commitment only in type II consideration.
There was no contribution of supervisor-subordinate communication in continuance commitment according to
the two types of leader’s consideration. In conclusion, the level of affective commitment is different among
nursing staff and depends on quality of the leader and member communication and leaders’ consideration.
Especially in higher level of leader consideration and mutual communication, dependency of the nursing staff
will increase. However, the continuance commitment depends on other factors which were not considered in
current study.
