Biopsychosocial functioning and pain self-efficacy in chronic low back pain patients Alex L. Koenig, MS; Amy E. Kupper, MS; Jay R. Skidmore, PhD; Karly M. Murphy, BA
Aim • Examine relationship between biopsychosocial functioning and pain severity and whether it is mediated by pain self-efficacy (PSE). • Relevance • Chronic low back pain (CLBP) is primary cause of disability and workplace absenteeism, and cost to society is staggering. • Little research involving CLBP patients has studied dynamic interaction among biological, psychological, and social factors.
Method • Study used archival data from multidisciplinary pain management program. • 99 individuals with CLBP completed measures of biological, psychological, and social functioning; pain severity; and PSE at admission. • 69% female. • Aged 18 to 72 yr. • Structural equation modeling and bootstrapping techniques were used to test significance of mediated model.
Results • Lower biological functioning and social functioning significantly predicted higher pain severity. • Lower social functioning significantly predicted lower PSE. • PSE did not mediate relationship between biopsychosocial functioning and pain severity. • Psychological functioning did not significantly predict pain severity or PSE.
Conclusion • Social functioning is an important factor in predicting outcomes and has numerous treatment implications.
