Development and Preliminary Validation of the Gender Identity Dimensions Clinical Tool among Hispanic Individuals

This study aimed to 1) develop a clinical instrument that explores the dimensions of gender identity, 2) validate the instrument, and 3) determine if the responses were answered by social desirability. This study used a non-experimental mixed methods, instrumental and cross-sectional design. The first phase of this study was the development of the instrument. After a literature review, three dimensions were established: 1) gender roles, 2) personal gender expressions, and 3) socially perceived gender expressions. The second phase consisted of a content validation process by eight expert judges and content validity. Lastly, the third phase consisted of recruiting a sample for the tool reliability documentation. A total of 321 people completed the survey. Internal consistency analysis showed that the tool dimensions has an acceptable internal consistency. Results showed variability regarding gender identity and adequate discrimination indices. Finally, the reliability of all the dimensions and time elements of the instrument showed satisfactory values. Results shows that all dimensions seem not to have been responded by social desirability. This study provided preliminary evidence that the Spanish version of the Gender Identity Dimensions Clinical Tool is a valid and reliable instrument to use with Hispanic individuals in a clinical setting.
