- OBJECTIVES:To assess the extent to which perceived pain and psychological factors explain levels of disability and health-related quality of life (HRQOL) in patients scheduled for lumbar fusion surgery, and to test the hypothesis that relationships between pain intensity, mental health, fear of movement/(re)injury, disability and HRQOL are mediated by cognitive beliefs and appraisals.DESIGN:Cross-sectional, correlation study.SETTING:Orthopaedic outpatient setting in a tertiary hospital.PARTICIPANTS:One hundred and seven chronic back pain patients scheduled for lumbar fusion surgery.MEASURES:Visual analogue scale for pain intensity, Short Form 36 mental health subscale, Tampa Scale for Kinesiophobia, Back Beliefs Questionnaire, Self-efficacy Scale, Coping Strategy Questionnaire, Oswestry Disability Index and European Quality of Life Questionnaire.RESULTS:The group effect of multiple mediators significantly influenced the relationships between pain intensity and mental health, fear of movement/(re)injury, functional disability and HRQOL. Pain catastrophising significantly mediated the relationship between pain intensity and mental health, control over pain significantly mediated the relationship between mental health and functional disability, self-efficacy and pain outcome expectancy significantly mediated the relationship between mental health and HRQOL, and self-efficacy also significantly mediated the relationship between pain intensity, fear of movement/(re)jury and functional disability. The model explained 28, 30, 52 and 42% of the variation in mental health, fear of movement/(re)injury, functional disability and HRQOL, respectively.CONCLUSIONS:This study highlights the strong influence and mediation roles of psychological factors on pain, mental health, fear of movement/(re)injury, disability and HRQOL in patients scheduled for lumber fusion. Future research should focus on screening as well as pre- and post-operative interventions based on these psychological factors for the potential improvement of lumber fusion surgery outcomes.Copyright 2010 Chartered Society of Physiotherapy.
