Reduced pain interference and catastrophizing linked to better sleep

A secondary mediation analysis of a 3-arm randomized trial (N=223) in chronic low back pain compared 8-session CBT, 1-session Empowered Relief, and 1-session health education. The study reported that reductions in pain interference and catastrophizing, but not pain intensity, were associated with significant indirect pathways to improved sleep disturbance, with pain self-efficacy contributing a partial indirect pathway; CBT and Empowered Relief showed similar indirect effects and were pooled for primary analyses.

Most relevant for: Patients with chronic low back pain who also experience co-occurring sleep disturbance.
