title: Self-efficacy in multimorbid elderly patients with osteoarthritis in primary care--influence on pain-related disability.
abstract: The impact of self-efficacy on pain-related disability in multimorbid elderly patients in primary care is not known. The aim of our study was to analyze the influence of self-efficacy on the relation between pain intensity and pain-related disability, controlled for age and disease count, in aged multimorbid primary care patients with osteoarthritis and chronic pain. Patients were recruited in the German MultiCare study (trial registration: ISRCTN89818205). Pain was assessed using the Graded Chronic Pain Scale, and self-efficacy using the General Self-Efficacy Scale. We employed SPSS for statistical analysis. One thousand eighteen primary care patients were included in the study. Correlation analyses showed significant correlations between pain intensity and pain-related disability (r = 0.591, p < 0.001), pain intensity and general self-efficacy (r = 0.078, p < 0.05), and between general self-efficacy and pain-related disability (r = 0.153, p < 0.001). Multiple mediator analysis gives indications that self-efficacy partially mediates the relation between pain intensity and pain-related disability. In our results, we found little evidence that self-efficacy partially mediates the relation between pain intensity and pain-related disability in aged multimorbid primary care patients with osteoarthritis and chronic pain. Further research is necessary to prove the effect.
