Résumé : To evaluate the level of work satisfaction of staff working in rehabilitation services based on the Effort-Reward Imbalance Model. A cross-sectional study among rehabilitation services staff working in 10 healthcare facilities in Jeddah. Total of 166 therapists and assistants working in the departments of physical, occupational and respiratory therapy are recruited from 10 healthcare facilities of the Jeddah area. The effort-reward imbalance and staff job satisfaction were measured using self-administered survey questionnaires. A comparatively higher effort reward imbalance ratio and low satisfaction in work is seen for foreign nationals, respiratory therapists and night schedule workers. The age, higher educational levels of the therapists and adult, geriatric and inpatients' caseloads are also positively associated with a high effort reward imbalance ratio. Job satisfaction of rehabilitation services staff based on the Effort Reward Imbalance Model is significantly correlated to the variables of age, nationality, rehabilitation specialty, work schedule and the type of patients treated which reflects an increased work stress for these professional categories. Workload, professional growth and financial benefits are essential determinants of job satisfaction of rehabilitation services staff. © Medwell Journals, 2012.
