Slide 3 - Consistência Interna: Pró-fórmula α=.743, ω=.751; Pró-aleitamento α=.716, ω=.723 - boa fiabilidade.

  • Internal consistency evaluated via Cronbach's α and McDonald's ω coefficients.
  • Pro-formula scale shows good reliability: α = .743, ω = .751.
  • Pro-breastfeeding scale demonstrates good reliability: α = .716, ω = .723.
  • Both scales exhibit satisfactory internal consistency overall.
