Résumé : To evaluate the level of work satisfaction based on the Effort-Reward Imbalance Model of staff working in rehabilitation services of different categories (in teaching, profit making and non-profit making hospitals). Participants were 166 therapists and assistants working in the Departments of Physical, Occupational and Respiratory Therapy from 10 hospital centers classified per three different categories in the Jeddah area. Effort-Reward Imbalance and staff satisfaction with intrinsic and extrinsic variables were measured by a self-administered questionnaire. There is a significant difference of level of job satisfaction measured by effort and reward imbalance between the therapists and assistant therapists working in the teaching, private or non-profit making health care facilities. In comparison by hospital type, the surveyed rehabilitation staffs presented a higher mean effort-reward imbalance in the teaching hospitals but higher job satisfaction with their salary, their perception of salary comparatively to others, yearly performance appraisal grading and affective commitment. In the rehabilitation services of non-profit making hospitals, the surveyed therapists and assistant therapists had the lowest mean Effort-Reward Imbalance ratio explained by their satisfaction with the variables of patient/staff ratio and emotional attachment to the organization. In the profit making healthcare facilities, the surveyed staffs are comparatively more satisfied with the variables of doctors' respect, involvement in quality improvement or educational lectures and transportation to/from work. Rehabilitation services staffs working in teaching hospitals and profit making hospitals had in general a higher effort-reward imbalance ratio with work stress and low satisfaction in work compared to the non-profit hospital facilities. Job satisfaction of rehabilitation staff varies per hospital type and mission of the health care facility. © Medwell Journals, 2012.
