Objectives:
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.
Methods:
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.
Results:
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.
Conclusions:
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.
