Evaluation of the Coping Strategies Questionnaire-Revised for fatigue in systemic sclerosis: a Scleroderma Patient-centred Intervention Network (SPIN) cohort study
Authors' conclusion
The CSQ-R-Fatigue may not be appropriate to assess coping with fatigue in SSc due to possible biases related to language and disease severity.
Study context
- Population
- SPIN Cohort participants with systemic sclerosis (SSc) completing the CSQ-R-Fatigue88% female
- Participants
- 863 participants
- Outcome
- Psychometric properties of the CSQ-R-Fatigue
Methodological detailspsychometric evaluation, confirmatory factor analysis, differential item functioning analysis, test-retest reliability
- Psychometric evaluation
- Confirmatory factor analysis
- Differential item functioning analysis
- Test-retest reliability
Main finding
As reported in the abstract
- 6-factor Coping Strategies Questionnaire-Revised (CSQ-R) structure replicated: Tucker-Lewis Index
- 0.95
- Comparative Fit Index
- 0.97
- Root Mean Square Error of Approximation
- 0.05
- Substantive differential item functioning (DIF) by language: items on factors
- 11 items on 6 factors
- Substantive DIF by disease subtype: items on factors
- 10 items on 5 factors
- Factor-score differences due to DIF ≥0.20 SMD (language and subtype)
- 4 factors each
- Test-retest reliability (intraclass correlation), lowest factor
- 0.68 [95% CI 0.58, 0.76]
- Test-retest reliability (intraclass correlation), highest factor
- 0.91 [95% CI 0.88, 0.93]
Observational data: associations, not effects.
