Implication

Randomized trial validates the Arabic Quality-of-Life Scale in teachers, indicating reliable assessment for quality of life.

Key Points

  • The central aim was to validate the Arabic version of the Quality-of-Life Scale (QOLS) and assess its psychometric properties among teachers.
  • Sample included 401 teachers: 235 general education and 166 special education teachers.
  • Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to evaluate the scale's structure and reliability.
  • Analyses included Cronbach’s alpha, McDonald’s omega coefficients, and convergent/discriminant validity assessments.
  • EFA revealed a two-factor solution explaining 55.6% of the variance, with excellent internal consistency (Cronbach’s alpha = 0.91, McDonald’s omega = 0.92).
  • CFA indicated acceptable model fit (CFI = 0.92, TLI = 0.90, RMSEA = 0.085, SRMR = 0.05) supporting the stability of the two-factor structure.
  • Measurement invariance was achieved across gender, but not across educational levels.
