Background: Psychological flexibility (PF) and self-compassion (SC) are both associated with positive outcomes for people living with chronic pain. Despite overlapping processes and shared concepts between the two constructs, they have mostly been studied independently. Aims: The present study aimed to determine the relationship between PF and SC, and investigate their role in relation to pain interference, work and social adjustment, and depressive symptoms. Method: 420 participants attending a speciality chronic pain service completed a battery of measures prior to starting treatment. Data were collected on the Self-Compassion Scale Short Form, Chronic Pain Acceptance Questionnaire, Self Experiences Questionnaire, Committed Action Questionnaire, Brief Pain Inventory Interference Scale, Work and Social Adjustment Scale, and Patient Health Questionnaire. Correlation analyses were performed to examine the relationship between PF and SC. Then hierarchical regression analyses examined the distinct and combined contributions of PF and SC to the variance explained in pain outcomes. Results: PF and SC variables were significantly and positively correlated with one another (r=.38 to .56). Correlation coefficients did not exceed .85 and therefore discriminant validity between the two constructs was satisfied and they were entered separately in the regression analyses. The final models for all three pain outcomes were significant, explaining 42% of the variance in pain interference, 36% in work and social adjustment, and 30% in depression. SC accounted for significant unique variance in each of the pain outcomes, however this was no longer significant when PF variables were added to the model for pain interference and work and social adjustment. Conclusion: PF and SC may be considered related but distinct constructs in the context of chronic pain. It was indicated that PF processes may account for the effects of SC on pain interference and work and social adjustment. However, SC appears to play an independent role in depression. Given the high comorbidity of depression, it may be beneficial to trial SC-based interventions or expanding existing interventions to include SC, in order to improve overall wellbeing for people with chronic pain.
