Domain specific self-efficacy mediates the impact of pain catastrophizing on pain and disability in overweight and obese osteoarthritis patients.

ABSTRACT:

Unlabelled

This study examined whether self-efficacy mediated the relationship between pain catastrophizing and pain and disability. Participants were 192 individuals diagnosed with osteoarthritis (OA) of the knees who were overweight or obese. Multiple mediator analyses were conducted to simultaneously test self-efficacy for pain control, physical function, and emotional symptoms as mediators while controlling for demographic and medical status variables. Higher pain catastrophizing was associated with lower self-efficacy in all 3 domains (Ps < .05). Self-efficacy for pain control fully mediated the relationship between pain catastrophizing and pain (beta = .08, Sobel test Z = 1.97, P < .05). The relationship between pain catastrophizing and physical disability was fully mediated
