Spanish: p = 0.01; Portuguese: p = 0.05.

df = degrees of freedom.

* A model with three factors is proposed: 1) “Views of health social care and mental illness”; 2) “Disclosure and knowledge of mental illness”; and 3) “Distinguishing mental/physical health.” These reference indices were used: chi-squared test of model fit (p > 0.05), root mean square error of approximation < 0.08, comparative fix index > 0.90, and Tucker-Lewis index > 0.90.
