Abstract : Background and Objectives: Office workers are found to be at great risk in developing work-related musculoskeletal disorders leading to reduced performance. Existing instruments may not fully capture region-specific occupational exposures and contextual factors relevant to specific populations. Hence, this study was carried out to develop and validate a self-structured questionnaire to assess the prevalence of musculoskeletal disorders among employees of ArSRLM, based on their work culture. Furthermore, a pilot study was conducted to assess the feasibility and comprehensibility of the questionnaire.  Methods and Methodology: A comprehensive literature review was done to understand more on musculoskeletal disorders and roles and responsibilities of the employees of ArSRLM. Based on which a self-structured questionnaire was generated specifically to assess the prevalence of MSDs among employees of the ArSRLM. The questionnaire was distributed to experts for face validity and content validity. The accuracy of the items of the questionnaire was identified through the content validity index. The internal consistency of the questionnaire was assessed using the Cronbach’s alpha method. The feasibility and comprehensibility of the questionnaire was determined by conducting a pilot study.  Result: The final questionnaire after validation and pilot testing consisted of 4 parts with 19 questions. Part I - the Demographic detail, Part II – Occupational Detail, Part III – Job description and Part IV consisted information on their Health Status. The I-CVI value for items showed that the items were highly relevant. The S-CVI (S-CVI average = 20.2/21 = 0.96, S-CVI average proportion = 4.8/5 = 0.96, S-CVI average universal agreement = 17/21 = 0.81) value showed that the questionnaire had excellent content validity. The internal consistency calculated using the Cronbach’s alpha was 0.78, interpreting good reliability.  Conclusion: The self-structured questionnaire is found to be a valid and reliable instrument for assessing prevalence of musculoskeletal disorders among the employees of ArSRLM. The scale can also determine the associated risk factors of MSDs in their occupational settings.
