Fear Avoidance Beliefs, Held by Occupational Therapists, are Associated with Treatment Recommendations

Abstract

Introduction: The purpose of this research was to explore whether New Zealand occupational therapists' recommendations for chronic low back pain are predicted by their fear avoidance beliefs. Method: In an online survey, 63 therapists rated the strength of recommendation on a four-point Likert scale (for each of: home help, equipment provision, and environmental modification) for a case study of low back pain, and completed two questionnaires about fear avoidance beliefs. The strength of recommendation (definitely not, not likely, likely, definitely yes) was analysed as an ordinal scale response variable, with important predictors each of the Fear Avoidance Beliefs Tool and the Health Care Providers Pain and Impairment Relationship Scale. Potential confounding variables were: age, years in practice or pain practice, and receipt of extra pain education. The main response variable was the probability of recommending home help. Analysis was by proportional odds regression. Findings: 54/63 (85.7%) of the surveys had complete data. The adjusted odds ratio, per point higher on the fear avoidance belief scales, for therapists who were more likely to recommend home help was 1.19 (95% CI 1.06 to 1.35), p = 0.005 for the Fear Avoidance Belief Tool and 1.16 (95% CI 1.04 to 1.29), p = 0.006 for Health Care Providers Pain and Impairment Relationship Scale. This is consistent with those with greater fear avoidance beliefs being more likely to recommend home help. Conclusion: Occupational therapists' fear avoidance beliefs are associated with treatment recommendations that lessen activity or movement demands. These beliefs are potentially unhelpful and may reinforce avoidance behaviour in patients with chronic low back pain.
