Validation of the Chinese Version of the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults

The number of individuals with potential gender dysphoria (GD) being referred to specialized gender identity clinics or programs is increasing internationally; these cases are initially screened using the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA).The current study aimed to assess the psychometric properties of the GIDYQ-AA in a sample of adolescents and young adults from China.A cross-sectional study was conducted in October 2020. Sociodemographic information of the participants was first collected. Participants then completed the GIDYQ-AA, the Generalized Anxiety Disorder-7 scale, the Patient Health Questionnaire-9, and a suicidal ideation assessment. A total of 2,533 participants with a mean age of 19.30 (SD = 1.19) years were recruited. Of the participants, 841 (33.2%) were cis men, 1,589 (62.7%) were cis women, 66 (2.6%) self-identified as transgender, 17 (0.7%) self-identified as non-binary, and 20 (0.8%) self-identified as gender queer.The GIDYQ-AA had high internal consistency with a Cronbach's alpha = 0.89. Exploratory factor analysis showed that the GIDYQ-AA had a four-factor structure in China. The GIDYQ-AA was significantly correlated with anxiety symptoms (r = -0.32, P < .01), depressive symptoms (r = -0.33, P < .01), and suicidal ideation (r = -0.20, P < .01).The Chinese version of GIDYQ-AA is a useful measurement with high practical value, which could promote the assessment and research of GD across China or among Chinese migrants in other countries.This is the first study assessing the psychometric properties of the GIDYQ-AA in Chinese adolescents and young adults. The convergent and divergent validity of the GIDYQ-AA were not examined due to the unavailability of data. Also, the sample did not have an equal distribution of male to males and female to females.The Chinese version of GIDYQ-AA is a useful measure, which could promote both the assessment and research of GD in the Chinese population.
