Note. ANOVAs were conducted for all other measures. Levene's test revealed that assumption of homogeneity of variances was violated for DERS-16 (p = .02) and BBQ (p = .02), thus these two ANOVAs were conducted without assumption of equal variances. For bias index, a Tukey's test revealed that the 2D neutral group had a significantly lower average bias index at baseline compared to the 2D disgust and 3D disgust groups.

p < .05. For between-groups comparison, Pearson's chi-squared tests were conducted for sex and education.
