Low back pain (LBP) is one of the leading causes of work disability, and psychosocial factors are associated with returning to work after an episode of LBP. However, the complex and overlapping effects between psychosocial variables have been difficult to assess using traditional linear modeling techniques. The aim of this paper is to develop and test a model of direct and indirect relationships among psychosocial predictors of return-to-work (RTW) outcomes following the onset of LBP. By exploring the potential for indirect, as well as direct relationships with RTW outcomes, we hope to better understand the RTW process and why pain does not always directly lead to outcomes.
Secondary analysis of a larger study of adults seeking treatment for work-related back pain with recent onset. In total, 241 participants who completed a baseline survey, a short follow-up survey, and a longer follow-up survey after 3 months were included in our analyses. The participants were required to have LBP with onset of less than 14 days, be 18 years or older, and be fluent in English or Spanish. The analyses utilized structural equation models to test the direct and indirect relationships among the variables and RTW outcomes at 3 months.
Our results indicated a good fit for our model (χ2=69.59, df=45, p<.05; RMSEA=.05; CFI=.95; WRMR=.61). Pain, catastrophizing, fear-avoidance beliefs, organizational support, and RTW confidence were all found to have indirect relationships with the outcomes. RTW confidence and RTW expectations were found to have direct relationship with the outcomes.
