Introduction: Improvement of healthcare management and quality and assurance of services for the public and healthcare system have been increasingly taken into consideration. The present study evaluates the relationship between coaching management style and quality of the services in teaching hospitals of Yazd in 1391 using a PLS path modeling approach. Methods: Data were gathered using adescriptive-correlative method. The subjects included clinical professionals and the patients in Yazd teaching hospitals(n=300 in each). Two questionnaires including "assessment of coaching management skills" and "quality of services" were used. Data analysis was carried out by Smart PLS and SPSS softwares. Results: According to PLS model, the structural relationship between coaching and quality of services was estimated as -0.194 showing aninverse relationship between coaching skills and quality of services. Afshar Hospital with the lowest average in coaching skills showed higher average of service quality compared to the other two hospitals. It follows that as the tendency towards coaching skills increases in a hospital, patients' perceptions of the service quality decreases. Conclusion: It seems that as yet the managers have not well applied coaching skills and team works in the hospitals. This can be caused by the hospital organizational culture, differences in the wards, excess expectations of the staff and other reasons. The findings of this study suggestsrunning of the hospitals by a Benevolent-Authoritative management style with a team work approach so that the staff and patients satisfaction is met.
