Introduction: Low back pain (LBP) is a considerable health problem in many countries and may sometimes last for more than 12 weeks. It is the most common cause of functional disability affecting the adult group with a prevalence rate of 84%. Purpose: A reliable and valid goal-oriented performance analysis using a Likert scale for therapist´s satisfaction in treating subjects with low back pain (LBP) has been lacking globally. Therefore, a questionnaire used for therapist´s satisfaction in treating low back pain (LBP) is developed and validated. Subjects and methods: In the first phase, the items in the initial questionnaire were selected as per the signs and symptoms of low back pain (LBP). In the second phase, the content validity was analyzed by sending the revised questionnaire to 30 physical therapists for their comments. In the third and fourth phases, the final revised questionnaire was sent to 120 practicing therapists for checking the consistency of the items. In the fifth phase, the final validity (factor analysis) and reliability (internal consistency) of the questionnaire were measured. Results: The final questionnaire consists of 32 items with six factors. The reliability (Cronbach's alpha coefficients) for items ranged from 0.67 to 0.85 and the stability (Guttman split-half coefficient) for test-retest ranged from 0.68 to 0.89. A validity test was done by a principle factor analysis with a cut-off score of 0.6. Conclusion: The physiotherapist satisfaction questionnaire was reliable and valid for finding the physiotherapist´s satisfaction in subjects with low back pain.
