Abstract Background context The fear-avoidance model offers a promising framework for understanding the development of chronic postoperative pain and disability. However, limited research has examined this model in patients undergoing spinal surgery. Purpose To determine whether preoperative and early postoperative fear of movement predicts pain, disability, and physical health at 6 months following spinal surgery for degenerative conditions, after controlling for depressive symptoms and other potential confounding variables. Study design/setting A prospective cohort study conducted at an academic outpatient clinic. Patient sample One hundred forty-one patients undergoing surgery for lumbar or cervical degenerative conditions. Outcome measures Self-reported pain and disability were measured with the Brief Pain Inventory and the Oswestry Disability Index/Neck Disability Index, respectively. The physical composite scale of the 12-Item Short-Form Health Survey (SF-12) measured physical health. Methods Data collection occurred preoperatively and at 6 weeks and 6 months following surgery. Fear of movement was measured with the Tampa Scale for Kinesiophobia and depression with the Prime-MD PHQ-9. Results One hundred and twenty patients (85% follow-up) completed the 6-month postoperative assessment. Multivariable mixed-method linear regression analyses found that early postoperative fear of movement (6 weeks) predicted pain intensity, pain interference, disability, and physical health at 6-month follow-up (p
