This study was designed to develop and evaluate a stage-matched intervention (SMI) in order to prevent and decrease musculoskeletal disorders among Iranian computer users, in Qazvin, Iran.METHODS: This Quasi experimental study was conducted on 150 computer users who spent at least 20 hours per week. They were randomly divided into experimental and control groups. The stage matched intervention was designed based on main constructs derived from the theory of planned behavior match to the individual’s stages of readiness for MSDs preventive behavior. A control group pre-and post-test design was used for evaluating the impact of the SMI. Educational intervention program lasted eight weeks.FINDINGS: The intervention group, compared to the control group, showed significant improvements in stages of change for preventive behavior from 2.63±0.71 to 3.49±1.05 (p M3 ER -
