Abstract

Research conducted in transgender and gender diverse individuals focused mainly on the challenges and health disparities affecting this population. One reason for this situation is the lack of questionnaires capturing positive aspects and experiences related to being a transgender person. The Transgender Positive Identity Measure (T-PIM) is one of a very few measures designed to explore such experiences. The aim of the study was to investigate the structure, reliability and validity of the Polish translation of the T-PIM questionnaire. A group of 89 transgender and gender diverse participants completed an online survey including the T-PIM questionnaire, resilience measurement scale (SPP-25) and depression (CESD-R) measures. Hierarchical item clustering method (ICLUST), Horn's parallel analysis and Velicer's minimum average partial test (MAP) were employed to investigate the structure of the questionnaire. The analyses showed that the Polish translation of the T-PIM questionnaire was characterized by a 5-factor structure consistent with the original publication (Authenticity, Intimacy, Community, Social Justice, Insights). Cronbach's alpha and Guttman's lambda-6 reliability coefficients reached satisfactory levels for all five factors and for the whole questionnaire. The Polish translation of the T-PIM questionnaire is characterized by satisfying psychometric properties and can be used in studies on transgender and gender diverse communities.

Highlights

Recent changes introduced to the DSM-5 [1] and the ICD-11 [2], concerning the terminology, content, and placement of gender dysphoria diagnoses constitute an important step towards the depsychiatrization of the experiences of transgender persons, and shifting the focus of research to include a more comprehensive picture of factors affecting the well-being of this population

Summary

Introduction

Recent changes introduced to the DSM-5 [1] and the ICD-11 [2], concerning the terminology, content, and placement of gender dysphoria diagnoses constitute an important step towards the depsychiatrization of the experiences of transgender persons, and shifting the focus of research to include a more comprehensive picture of factors affecting the well-being of this population. Advancing our understanding of resilience sources and positive self-definition in transgender individuals requires further studies and research tools tailored to capture the unique experiences of this population. One of such tools is the Transgender Positive Identity Measure (T-PIM) by Riggle and Mohr [7]. This questionnaire consists of 24 items describing positive experiences associated with being a transgender person, which are assessed on a 7-point Likert-type scale, ranging from 1—disagree strongly to 7—agree strongly.
