Psychometric Evaluation of the Heterosexist Harassment, Rejection, and Discrimination Scale: Identification of a Unidimensional 11-Item Scale.

Despite the Heterosexist Harassment, Rejection, and Discrimination Scale (HHRDS) being a routinely used measure of discrimination, there is no current consensus regarding its fundamental psychometric properties. This study sought to: (a) test the dimensionality of the scale using a classical test theory approach, and (b), if lacking a clear multidimensional structure, use an item response theory approach to develop a concise unidimensional measure and examine differential item and test functioning across various identity factors. In a sample of sexual minority adults ( = 1,243), evaluation of the HHRDS supported a reduced 11-item unidimensional measure.

Measurement Invariance of the Perceived Invalidation of Emotion Scale: An Examination Across Race/Ethnicity, Gender, Sexual Orientation, and Intersection of Identities.

The Perceived Invalidation of Emotions Scale (PIES), developed to measure emotional invalidation, could aid research efforts on various internalizing disorders and minority mental health. A prerequisite for its use includes its psychometric evaluation in diverse samples; thus, the current study aimed to evaluate the psychometric properties of the PIES in a combined sample of minoritized adults ( = 876). Results supported a unidimensional structure of the PIES that was invariant across the two minoritized samples, race/ethnicity, gender, sexual orientation, and intersections of race/ethnicity and sexual orientation.

The Self-Dehumanization Scale: Three Studies on Its Development and Validation.

Self-dehumanization, a phenomenon relevant to social psychology, has been somewhat absent from clinical psychology research. Furthermore, measures of self-dehumanization are few, and to our knowledge, no validated and generalizable self-report measure exists. To address this gap, we present a Self-Dehumanization Scale (SDS).
