Transformational leadership of clinical nutrition managers.
OBJECTIVE
To identify leadership qualities of clinical nutrition managers and associate these leadership qualities with selected demographic variables (eg, training/degree, length of time in management, number of people supervised, income, and participation in advanced practice activities).


METHODS
The theory of transformational leadership, that is, leadership that incorporates specific interpersonal behaviors of the leader and his or her actions within the organization, provided the framework for the study. Specific transformational leadership qualities--leader behavior, leader personal characteristics, and the effect of the leader on organizational functioning and culture--were measured using the Leadership Behavior Questionnaire (LBQ). The reliability and validity of the LBQ have been reported previously. Other data were obtained using two demographic surveys.


METHODS
Demographic surveys were mailed to 1,599 members of the Clinical Nutrition Management dietetic practice group. From the 951 (59.8%) respondents, a study sample of 150 clinical nutrition managers and their subordinates was selected to receive the LBQ; 116 (77.3%) instrument sets were used for analysis.


METHODS
Descriptive statistics were used to analyze the demographic surveys. A specified mixed linear model repeated measures Statistical Analysis System procedure was used to compare the clinical manager and subordinate LBQ scores. Association of the selected demographic variables with leadership qualities was measured by lambda, a predictive value measure, using the BMDP 4F program.


RESULTS
Clinical nutrition managers exhibited transformational leadership qualities as rated by the LBQ, rating lowest on the communication leadership score and highest on the respectful leadership score. Most of the clinical nutrition manager self LBQ scores were significantly higher than the clinical nutrition manager LBQ scores rated by subordinates. The selected demographic variables appeared to have the strongest predictive effect for the visionary culture building subscore of the LBQ. The visionary culture building subscore is a measure of how well the leader interacts with and affects the functioning of an organization.


CONCLUSIONS
More research is needed to define leadership in dietetics: this study can serve as a possible model. One way clinical nutrition managers may be able to enhance their leadership behaviors is to strengthen their skills in communicating their vision. Programs are needed to help clinical nutrition managers shape their organizations to foster leadership development in their subordinates.
