In this research we tested the hypothesis that the personality trait neuroticism, stress, and rumination are subjacent to anxiety and depression in individuals with Vitiligo. We also explored whether individuals’ gender might favor the onset or worsening of the psychological consequences of such disorders.

Transgender people have often been the target of widespread prejudice and discrimination. To better analyse this phenomenon it is necessary to have valid and reliable measures for this specific target group. This article describes four studies in which we developed the Prejudice against Transsexual Scale (PTS). In Study 1, we developed the items and analysed its content and semantic validities. The results allowed the retention of 42 items to be answered in Likert format, half referring to transsexual women (PTS-W) and the other half referring to transsexual men (PTS-M). In Study 2 (N = 300) we performed an exploratory analysis of the scale's factorial structure and performed an analysis of the quality of the items using the item response theory approach. The results indicate a single-factorial structure with two parallel sub-scales (PTS-W and PTS-M), each with 10 identical items and strong internal consistency. Study 3 (N = 237) gathered complementary evidence of factorial validity through confirmatory factorial analysis. Finally, Study 4 (N = 148) allowed us to analyse the convergent-discriminatory validity of the two sub-scales. The synthesis of the results indicates that the PTS presents consistent evidence of validity and reliability for the measurement of prejudice against transsexuals.
