Data are presented as means ± SE. Fisher's least significant differences (LSD) test was used for comparing mean raw scores of stigma factors. An unpaired t-test and Mann Whitney U test were used, as appropriate, for comparison between two groups. Pearson's correlations between neuroticism, extroversion, and the factors of stigma evaluated was computed, Kendall's tau (τ) coefficient was a statistic used to measure the association between the two measured quantities of education and secrecy.
