Background and purpose. The Fear Avoidance Model is used to explain why some patients with acute low back pain develop chronic low back pain (CLBP). Cognitive behavioural therapy (CBT) targeting dysfunctional behavioural cognitions (pain catastrophizing and fear of movement) is recommended. Purpose: to investigate whether a two-week CBT-based pain management program results in improvement in dysfunctional behavioural cognitions and whether these improved cognitions improve functional outcomes. Methods and Results. Cohort study including 524 consecutive CLBP-patients. Main outcome: functioning (ODI). Secondary outcomes: pain severity (NRS), pain catastrophizing (PCS), fear of movement (TSK). Assessments: pre- and post-treatment, 1 and 12-months follow-up (FU). Improvement over time was analysed with repeated measures ANOVA. Path analyses were used to examine the influence of pain catastrophizing and fear of movement on functional disability and pain severity. Multiple imputation was used to complete missing data. Participants with incomplete data (12.8%) did not differ from those with complete data (n= 457). 59% were females, mean age 46 (± 9.5) years, mean CLBP-duration 12 (± 10.8) years. All outcomes significantly improved at post-treatment and a slight significant improvement between post-treatment and 12 months FU was observed. Path analyses showed a direct effect for catastrophizing on post-treatment functioning and an indirect effect for catastrophizing through fear of movement on post-treatment functioning. Comparable results with pain severity as outcome. Conclusion. A two-week pain management program improved dysfunctional behavioral cognitions and functional outcomes in patients with longstanding CLBP up to one year. Targeting both pain catastrophizing and fear of movement during the program resulted in improved outcomes. Conflicts of Interest: JK O'Dowd is director of and shareholder in RealHealth.

Background. Emerging research has indicated that ‘significant others’ (spouses/relatives) may have important influences on continued work participation for individuals with chronic non-specific musculoskeletal pain (CMP). In order to expand on this novel area of research, data from studies conducted in The Netherlands and the UK were assimilated. Method. In both studies, worker and significant other perceptions of pain self-efficacy, perceived partner responses to pain, pain catastrophizing, and contribution to work participation were explored in relation to the worker's CMP. In the Netherlands, questionnaire data were collected from workers with CMP and their significant others (n=103), and in the UK, in-depth semi-structured interviews were conducted (n=10). Appropriate quantitative and qualitative analysis techniques were applied. Results. In the Dutch study, moderate to high levels of perceived pain self-efficacy, moderate levels of significant other solicitous and distracting responses, and low levels of significant other punishing responses and catastrophizing were reported by both significant others and workers. Significant others were viewed as crucial in helping maintain continued work participation by workers with CMP. Overall group averages indicated no significant differences, with the exception of greater pain catastrophizing reported by significant others (14.4 versus 11.1 p<0.01), although this was not deemed clinically relevant (ES=0.34). Qualitative data from the UK study supports these findings, further elaborating on the above concepts. Conclusions. This study adds further weight to the evidence which recognizes the importance of social context for successful pain management and vocational rehabilitation interventions.

Purpose. Health literacy, the ability to seek, understand and utilise health information, is important for health and health-related decisions. Suboptimal health literacy is associated with poorer health outcomes in many chronic conditions although this has not been studied in chronic low back pain (CLBP). This study explored health literacy in a community cohort with and without CLBP. Methods and results. 117 adults, comprising 61 with no history of CLBP and 56 with CLBP (28 with low and high disability, respectively, determined by a median split in Oswestry scores) participated. Using a mixed methods approach, data were collected on pain severity, LBP-related disability, fear avoidance, LBP beliefs, pain catastrophizing and health literacy was measured using the Short-form Test of Functional Health Literacy in Adults (S-TOFHLA). In-depth interviews were undertaken with 36 CLBP participants to explore beliefs about LBP and experiences in seeking, understanding and using LBP information. LBP-related beliefs and behaviours, rather than pain intensity and health literacy skills, were associated with disability related to LBP. Individuals with CLBP-high disability had poorer back pain beliefs and increased fear avoidance behaviours relating to physical activity. Although S-TOFHLA scores suggested adequate health literacy across all participants and these were not related to LBP beliefs and attitudes, interviews revealed that individuals with CLBP-high disability adopted a more passive coping style and had a patho-anatomical view of their disorder compared to individuals with CLBP-low disability. Conclusion. While participants with CLBP have adequate S-TOFHLA scores, qualitative data revealed barriers in seeking, understanding and utilising LBP information
