Systematic review of the psychometric properties of transphobia scales

Introduction: Prejudice and discrimination against transgender individuals (i.e., transphobia) is pervasive and has been shown to have pernicious effects on the physical (e.g., substance abuse and other self-harm behaviors) and psychological (e.g., depression and suicidal ideation) well-being of those targeted.

Aims: To date, a review of the psychometric properties of scales assessing transphobia has not been conducted; this gap compromises researchers' ability to make informed measurement decisions.

Methods: In the current study, 61 articles that contained 83 scales were identified, and their adherence to best practices in psychometric testing was evaluated.

Results: Most of the transphobia scales included in the current review did not provide sufficient information about item generation and refinement, scale dimensionality, scale score reliability, or validity. Each scale was entered into a table and was ranked on the basis of its total score. A score of 1 was issued for each psychometric feature that adhered to best practice guidelines, with total scores ranging from 0 to 5 (i.e., higher scores denote greater psychometric soundness).

Discussion: Properties of the reviewed scales are summarized and recommendations are made for future transphobia scale development and validation. The measures that emerged as possessing the highest scores and, subsequently, the greatest utility are identified.     

An Exploratory Study of Integrative Personality Pathology Systems and the Interpersonal Circumplex

Normative and pathological personality traits are theoretically associated with interpersonal behavior patterns and difficulties. However, little is known about relations between dimensional personality systems that integrate pathological and normative traits and social functioning. The current study explores the projections of scales from two integrative frameworks, the Dimensional Assessment of Personality Pathology and the Schedule for Nonadaptive and Adaptive Personality, onto interpersonal circumplex traits and problems. The DAPP and the SNAP demonstrated similar overall validity in predicting the interpersonal domain. Results suggest a novel framework for understanding personality—interpersonal behavior relations by categorizing scales according to their: a) minimal, b) non-specific, c) specific, and d) differential relations to interpersonal traits and problems with important implications for future research relating clinical constructs to interpersonal behavior as well as clinical assessment and behavioral predictions based on SNAP and DAPP scales.     

Estradiol or diarylpropionitrile administration to wild type, but not estrogen receptor beta knockout, mice enhances performance in the object recognition and object placement tasks

Cognitive processes mediated by the hippocampus and cortex are influenced by estradiol (E₂); however, the mechanisms by which E₂ has these effects are not entirely clear. As such, studies were conducted to begin to address the role of actions at the β form of the intracellular estrogen receptor (ERβ) for E₂’s cognitive effects in adult female mice. We investigated whether E₂ improved performance of wild type (WT) and ERβ knockout (βERKO) mice in tasks considered to be mediated by the cortex and hippocampus, the object recognition and object placement tasks. WT and βERKO mice were ovariectomized (ovx) and E₂ (0.1 mg/kg), an ERβ selective ER modulator (SERM), diarylpropionitrile (DPN; 0.1 mg/kg), or oil vehicle was administered to mice following training in these tasks. We hypothesized that if E₂ has mnemonic effects, in part, due to its actions at ERβ, then WT mice administered E₂ or DPN would have improved performance compared to vehicle WT controls, which would not be different from βERKO mice administered vehicle, E₂ or DPN. Alternatively, activation of ERα (with E₂, which is a ligand for both ERα and ERβ) may produce opposing effects on cognition and/or the activation of ERα and ERβ vs. either receptor isoform alone may produce a different pattern of effects. Results obtained supported the hypothesis that ERβ activation is important for mnemonic effects. Ovx WT, but not βERKO, mice administered E₂ or DPN had a greater percentage of time exploring a novel object in the object recognition task and a displaced object in the object placement task. Thus, actions at ERβ may be important for E₂ or SERMs to enhance cognitive performance of female mice in the object recognition and placement tasks.     

Affective responses to non-sexual imagery depicting gay men and lesbian women

ABSTRACT

When examining negative attitudes and behaviors directed toward gay men and lesbian women (i.e., homonegativity), researchers tend to use measures that require participants to respond to belief statements. This methodology is problematic for two reasons: 1) it focuses on the social categories “gay men” and “lesbian women” and ignores the practices of relational intimacy engaged in by gay and lesbian persons (practices that, arguably, are at the crux of homonegativity); and 2) it overlooks the affective responses that sexual minorities evoke in heterosexual people. These issues were tackled in the current study. Specifically, heterosexual participants (N = 241) were asked to report their affective state using six basic emotions while viewing photos depicting male-male, female-female, and heterosexual couples. Findings demonstrated that participants, regardless of gender, reacted most negatively to images of female-female couples engaging in everyday intimacies. Theoretical explanations for these findings are explored.
