Overview

Psychometric evaluation of self-management skills checklist shows cultural adaptation in AYAs with sickle cell disease across Brazil and the US, indicating measurement invariance.

Key Points

  • This study aims to evaluate the psychometric properties and cross-country measurement invariance of the Self-Management Skills Checklist.
  • Translated SMSC into Brazilian Portuguese and culturally adapted it.
  • Analyzed data from 398 AYAs with sickle cell disease in Brazil and the US.
  • Used Cronbach's alpha for internal consistency and confirmatory factor analysis for structural evaluation.
  • Assessed measurement invariance across countries and imputed missing data using random forest methods.
  • SMSC demonstrated acceptable reliability with a global alpha of 0.75 and acceptable fit indices for a two-factor model.
  • A reduced 14-item model showed improved fit (RMSEA=0.03, CFI=0.98, TLI=0.98) for invariance testing.
  • Configural and metric invariance supported, indicating differences in item interpretation across cultures.
