Worker recovery expectations and fear-avoidance predict work disability in a population-based workers' compensation...

Area of Science:

• Occupational health
• Epidemiology
• Musculoskeletal disorders

Background:

• Prolonged work disability from back pain is a significant issue.
• Previous studies on risk factors have been inconsistent and limited in scope.
• Psychosocial factors require further prospective investigation.

Purpose of the Study:

• To identify demographic, pain, disability, and psychosocial predictors of 6-month work disability.
• To analyze factors assessed shortly after the onset of work-related back pain.
• To understand risk factors for chronic work disability.

Main Methods:

• Prospective, population-based cohort study of 1,068 workers with back pain claims.
• Telephone interviews conducted median 18 days post-claim for demographic, pain, disability, and psychosocial data.
• Administrative data used to determine 6-month work disability status.

Main Results:

• 18.4% of workers experienced 6-month work disability.
• Baseline pain, disability, age, race, and education predicted disability.
• High work fear-avoidance and low recovery expectations were significant independent predictors.

Conclusions:

• Acute work-related back pain with high pain and disability, low recovery expectations, and fear of work-related harm are risk factors for chronic disability.
• These findings highlight the importance of psychosocial factors in predicting work disability outcomes.
• Early identification of these risk factors can inform targeted interventions.
