The Psychometric Properties of the Connor-Davidson Resilience 10-Item Scale in Individuals With Fibromyalgia.

Abstract

Background/Purpose: Psychological resilience plays an important role in improving physical function among people living with fibromyalgia (FM). The Connor-Davidson Resilience 10-Item Scale (CD-RISC-10) was created to measure psychological resilience in clinical populations. The purpose of this article is to assess the reliability and validity of the CD-RISC-10 in adults with FM. Method: A descriptive online survey was conducted on 200 participants with FM registered in a national registry. Resilience was measured using the CD-RISC-10. The CD-RISC-10 was assessed for reliability and validity utilizing a Rasch analysis using the Winsteps statistical program. Results: There was evidence of item reliability for the CD-RISC-10, with an item separation of 5.09 and item reliability of .96. All items on the CD-RISC-10 fit with the concept of psychological resilience, evidenced by acceptable inlier-sensitive or information-weighted fit and outlier-sensitive fit statistics. When controlling for age, sex, and comorbidities, there was a significant relationship between resilience and physical function (R ² = .35, F = 22.43, p < 0.001) and resilience and pain intensity (R ² = .27, F = 16.83, p < 0.001). Conclusion: This study found the CD-RISC-10 to be a reliable and valid scale for assessing resilience in adults with FM.
