Abstract: (95 Views)
Background and Objectives: Office staff in health networks are exposed to adverse psychosocial factors and work-related musculoskeletal disorders (WMSDs) associated with improper working posture, which may reduce productivity. This study aimed to examine the relationships between psychosocial factors and WMSDs with productivity among administrative staff of a health network and to evaluate the effectiveness of an educational–ergonomic intervention on these outcomes.
Method: This quasi-experimental pretest–posttest study was conducted in 2024–2025 among 150 administrative employees of the Behbahan health network. Data were collected using the Copenhagen Psychosocial Questionnaire (COPSOQ III), the Hersey and Goldsmith ACHIEVE productivity questionnaire, and the Nordic Musculoskeletal Questionnaire (NMQ). Working posture was assessed using the Rapid Office Strain Assessment (ROSA) checklist in a random subsample (n=15). A three-month educational–ergonomic intervention (May–July 2025) was delivered in small groups and covered effective communication/teamwork, stress management, motivation/organizational commitment, social support, and ergonomic principles/healthy work behaviors. Data were analyzed in SPSS-26; statistical significance was set at 0.05.
Results: Overall psychosocial score was positively correlated with total productivity (r=0.633, p<0.01). WMSDs showed significant negative correlations with selected productivity dimensions (p<0.05). After the intervention, psychosocial dimensions and overall productivity improved significantly (p<0.001), with a marked increase in total productivity (2.82 to 4.03; Cohen’s d=1.51). WMSDs decreased significantly (5.36 to 4.24; p<0.001). No significant change was observed in ROSA score (p=0.640).
Conclusion: The educational–ergonomic intervention improved workplace psychosocial conditions and reduced musculoskeletal complaints, resulting in higher productivity among administrative staff in the health network. Controlled studies with longer follow-up are recommended.
