The research tools consisted of Paterson's job performance questionnaire, Scherer general self-efficacy, Key Indicator method and a five-point body map questionnaire for assessing body organs discomfort and prevalence. Data was analyzed using SPSS 19.
Results: There was a significant difference between the level of risk of musculoskeletal disorders and their job performance and between the risk of musculoskeletal disorders and the prevalence of musculoskeletal disorders. The lower back showed the highest prevalence of musculoskeletal disorders. There was a significant difference between the levels of risk of musculoskeletal disorders with job performance and also between musculoskeletal disorders with job performance and self-efficacy. The results showed a positive and significant relationship between job performance and self-efficacy.
Conclusion: The results indicated the role of self-efficacy in preventing behaviors that lead to exacerbation of musculoskeletal disorders.
