comparison of mean scores among these groups based on
the validity scale and clinical scale.

The results from Hochberg’s GT2 (Figure 1) indicate
significant differences in mean scores between certain
groups. Specifically, there was a significant difference
in Infrequency between top homosexual men and
heterosexual groups (p = 0.03), as well as between versatile
homosexual men and heterosexual groups (p = 0.02). The
