Abstract

Sedentary and awkward office work postures are generally considered the main causes of musculoskeletal disorders (MSDs). Previous assessment tools have many items for assessing the risk factors of office ergonomics. In this study, we aimed to develop an ergonomic risk factors assessment tool for Musculoskeletal disorders in office workers (ERAMO), a self-assessment tool that incorporates individual, psychosocial, physical, and environmental factors believed to influence MSDs development and to evaluate its psychometric properties. A pool of potential ERAMO items was developed from in-depth interviews and then rated by seven experts with experience in ergonomic fields using the standard Delphi technique. We anticipated that it would take at least three rounds to reach a consensus. The ratings determined which items to retain, resulting in a 29-item measure, followed by exploratory factor analysis to define the factors and internal consistency testing. The results of the exploratory factor analysis showed acceptable factor loading and internal consistency of all items. The findings of our 29-item ERAMO are useful for screening for risk factors of MSDs in office workers.
