Breastfeeding attitude scores were normally distributed: Shapiro–Wilk: w = 0.98, p = 0.33. BF: Breastfeeding. n = 80 (GM+ = 45; GM− = 35), F(5,74) = 2.64, p = 0.03, adjusted R 2 = 0.09, root mean square error = 7.20; Testing residual normality: Kolmogorov–Smirnov: k–s = 0.07, p = 0.82; Breusch Pagan/Cook‐Weisberg homoscedasticity test: X 2 (1) = 0.56, p = 0.45; There was no collinearity of the variables of the model according to the Inflation Factor Variance (IFV).
