Objective: The aim of this study is to assess the job satisfaction of the primary health care providers and the factors affecting it. Methods: This cross-sectional and descriptive study was carried out among the staff in The Public Health Care Centers (PHCC) by performing a questionnaire under direct observation. Results: Out of 310 people consisting of the study universe, 282 participants (94%) were reached. The participants were 104 doctors, 132 assistant health care providers and 46 others (janitors, drivers) The mean age of the participants was 37.21±7.70; 60.6% of them were women, 80.1% married, 96.5% graduated from at least High school. The mean of the general job satisfaction point of the participants in the study is 63.24±13.63. While the mean of the general job satisfaction point of the physicians and the nurses is found higher, the mean of the general job satisfaction point of janitors and other staff was found lower. The mean of the general job satisfaction point was found higher among the permanent and contract employee, women, health care staff, those whose wife/husband works, who chose his job willingly, more educated; who has longer working hours, high income, has 3 or less children and finds his job suitable for his skills; however the marital status, having children and age do not affect the mean job satisfaction point.Conclusion: Subjects having high income, found his job suitable for his skills, chose his job willingly had higher job satisfaction scores. This implies that there should be a wage balance among the staff with the same status. The lower job satisfaction score in PHCC indicates the necessity of improving the conditions of these centers.
