Self-efficacy in idiopathic inflammatory myopathies: associated factors, profiles and patient-reported outcomes
Authors' conclusion
SE in IIMs is associated with modifiable socioeconomic and psychological factors and with better health outcomes.
Study context
- Population
- Participants with idiopathic inflammatory myopathies (IIMs), other rheumatic diseases and non-rheumatic autoimmune diseases
- Participants
- 5,802 participants
- Exposure
- IIM vs other rheumatic diseases (RMDs) vs non-rheumatic autoimmune diseases
- Outcome
- Self-efficacy measured by the Self-Efficacy for Managing Chronic Disease (SEMCD) scale
Methodological detailshierarchical regression, k-means clustering, multivariable model
- Hierarchical regression
- K-means clustering
- Multivariable model
Main finding
As reported in the abstract
SE (SEMCD), median
IIM
5.3
median
RMDs

Observational data: associations, not effects.
Further findings
Factors associated with SE, fully adjusted integrated model
- Model R²
- 0.222
- Mental health comorbidity, B
- −0.898
- Financial difficulty, B
- −0.734
- Regular exercise, B
- 0.770
- Family support, B
- 0.150
PRO model of SE
- SE variance explained (R²)
- 0.483
- Resilience strongest positive association; fatigue and pain negatively associated
SE health profiles
- Four SE profiles identified; resilient-despite-burden subgroup
- 24%
- High symptom burden but preserved SE and mental health
Higher SE and patient-reported outcomes (PROs)
- Higher SE associated with better physical and mental health, greater resilience and life satisfaction, lower fatigue, pain and loneliness
- all P < 0.001
