The mediating role of psychological empowerment on job satisfaction and organizational commitment for school health nurses: a cross-sectional questionnaire survey.

Background: The importance of the professional role of school health nurses in promoting children's health in their school environment is widely recognized. However, studies of their working experience have revealed feelings of disempowerment that appear to be related to insufficient support from school managers. In these unsupportive working environments, it seems possible that psychological empowerment may play a mediating role to strengthen employees' satisfaction and commitment to their employing organization.
Objectives: The aim of this study is to test an exploratory model of empowerment in a Taiwanese sample of school health nurses by examining the mediating role of psychological empowerment in the relationship between external factors and work-related attitudes, specifically job satisfaction and organizational commitment.
Design: A cross-sectional survey with self-reported questionnaires.
Participants and Methods: Probability proportional sampling was used to generate a randomly selected sample of 500 school health nurses in elementary and junior high schools in Taiwan. A total of 330 valid questionnaires were returned, yielding a response rate of 66%.
Results: The exploratory model including all hypothesized variables provided an adequate fit (chi(2)=29.24; df=17; p=.052; adjusted goodness-of-fit index [AGFI]=.96; goodness-of-fit index [GFI]=.98; root-mean-square error of approximation [RMSEA]=.05) for the data and indicated that psychological empowerment did not fully mediate the relationship between organizational empowerment and job satisfaction because of the strong direct effects of organizational empowerment on job satisfaction. The influence of empowerment on organizational commitment was mediated through job satisfaction.
Conclusions: Psychological empowerment did not mediate the relationship between external factors and work attitudes, and job satisfaction emerged as an important factor. If school leaders can improve the job satisfaction of school health nurses, this will help them achieve greater commitment and loyalty of school health nurses to their employing schools.
