Abstract
PURPOSE: Lack of knowledge about computer ergonomics predisposes users to musculoskeletal and visual disorders. The present study examined the effect of a trans-theoretical model (TTM)-based educational program on work-related posture in office computer users. METHODS: This experimental study examined 102 hospital personnel whose primary job involved working at a computer. Participants were randomized to intervention and control groups. An educational intervention based on TTM was conducted over five sessions. A self-report questionnaire was used to collect data including stages of change, processes of change, pros and cons of change, and self-efficacy. A pen-paper-based observational method (i.e., Rapid Office Strain Assessment or ROSA) was used for assessing work posture. A visual analogue scale assessed pain intensity. Data were collected at baseline and 3-month follow-up. RESULTS: Significant differences were found on TTM's constructs and ROSA score between intervention and control groups at follow-up (p < 0.05). The mean ROSA score decreased from 5.65 (SD 1.03) to 3.95 (SD 0.83) in the intervention group, while no significant change was found in the control group. Pain intensity also decreased significantly among those in the intervention vs. control group (p < 0.001). CONCLUSION: An educational intervention based on TTM was effective in improving ergonomic posture in computer workers. Further research is needed to determine if these results can be generalized to computer workers in other settings.
