أثر الالتزام التنظيمي كمتغير وسيط في العلاقة بين نمط القيادة و الأداء الوظيفي : دراسة تطبيقية على مستخدمي مستشفى مغلاوي بميلة

الملخص EN

The purpose of this research is to study the effect of leadership style on job performance through the mediating role of organizational commitment.

For the purpose, four hypotheses were developed; the first three predicted positive relationships between leadership, organizational commitment and job performance and the last one suggested the mediating effect of organizational commitment.

86 employees in the hospital of Meghlaoua in Mila were surveyed.

Using spss23 and Amos21, the results of the study supported all the hypotheses.

Accordingly, leadership style had a positive impact on job performance; leadership style had a positive impact on organizational commitment; organizational commitment had a positive impact on job performance when leadership style was controlled.

The strength of the relation between leadership style and job performance was significantly reduced when organizational commitment was added to the model, suggesting the mediating role of organizational commitment.

In the light of the findings, it is suggested that merely positive relationship between leadership style and job performance may not automatically lead an employer to achieve the outcome-job performance.

Therefore, the secret of success lies in improving organizational commitment through solutions to enhance leadership style, thereby increase job performance.
