Systematic review of the psychometric properties of transphobia scales

Abstract

ABSTRACT 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.
