The potential buffering role of self-efficacy and pain acceptance against invalidation in rheumatic diseases

A substantial amount of people with a rheu-matic disease perceive invalidation consisting of lack of understanding and discounting (negative social responses). To get insight into the potential buffering role of self-effi-cacy and pain acceptance against invalidation, this cross-sectional study examined associations between these vari-ables. Spanish speaking people (N = 1153, 91% female, mean age 45 ± 11 years) with one or multiple rheumatic diseases completed online the Illness Invalidation Inven-tory, the Chronic Pain Acceptance Questionnaire, and the Chronic Disease Self-Efficacy Scale. Higher self-efficacy (t = − 4.80, p = < 0.001) and pain acceptance (t = − 7.99, p = < 0.001) were additively associated with discounting. Higher self-efficacy (t = − 5.41, p = < 0.001) and pain acceptance (t = − 5.71, p = < 0.001) were also additively associated with lack of understanding. The combined occurrence of high self-efficacy and high acceptance was associated most clearly with lower lack of understanding (interaction: t = − 2.12, p = 0.034). The findings suggest the usefulness of examining whether interventions aimed at increasing self-efficacy and pain acceptance can help people with rheumatic diseases for whom invalidation is a consider-able burden.
