Adolescents with Gender Dysphoria: Reflections on Some Contemporary Clinical and Research Issues
Archives of Sexual Behavior, 2019Co-Authors: Kenneth J ZuckerAbstract:This article provides an overview of five contemporary clinical and research issues pertaining to adolescents with a diagnosis of Gender Dysphoria: (1) increased referrals to specialized Gender identity clinics; (2) alteration in the sex ratio; (3) suicidality; (4) “rapid-onset Gender Dysphoria” (ROGD) as a new developmental pathway; (5) and best practice clinical care for adolescents who may have ROGD.

The Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults: Further Validity Evidence
Journal of sex research, 2010Co-Authors: Devita Singh, Heino F. L. Meyer-bahlburg, Joseph J Deogracias, Laurel L Johnson, Sarah J Kibblewhite, Susan J. Bradley, Allison Owen-anderson, Michele Peterson-badali, Kenneth J ZuckerAbstract:This study aimed to provide further validity evidence for the dimensional measurement of Gender identity and Gender Dysphoria in both adolescents and adults. Adolescents and adults with Gender identity disorder (GID) were compared to clinical control (CC) adolescents and adults on the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA), a 27-item scale originally developed by Deogracias et al. (2007). In Study 1, adolescents with GID (n = 44) were compared to CC adolescents (n = 98); and in Study 2, adults with GID (n = 41) were compared to CC adults (n = 94). In both studies, clients with GID self-reported significantly more Gender Dysphoria than did the CCs, with excellent sensitivity and specificity rates. In both studies, degree of self-reported Gender Dysphoria was significantly correlated with recall of cross-Gender behavior in childhood-a test of convergent validity. The research and clinical utility of the GIDYQ-AA is discussed, including directions for further research in distinct clinical populations.

the Gender identity Gender Dysphoria questionnaire for adolescents and adults
Journal of Sex Research, 2007Co-Authors: Joseph J Deogracias, Laurel L Johnson, Suzanne J Kessler, Justine M Schober, Heino F L Meyerbahlburg, Kenneth J ZuckerAbstract:The present study reports on the construction of a dimensional measure of Gender identity (Gender Dysphoria) for adolescents and adults. The 27-item Gender identity/Gender Dysphoria questionnaire for adolescents and adults (GIDYQ-AA) was administered to 389 university students (heterosexual and nonheterosexual) and 73 clinic-referred patients with Gender identity disorder. Principal axis factor analysis indicated that a one-factor solution, accounting for 61.3% of the total variance, best fits the data. Factor loadings were all ≥ .30 (median, .82; range, .34–.96). A mean total score (Cronbach's alpha, .97) was computed, which showed strong evidence for discriminant validity in that the Gender identity patients had significantly more Gender Dysphoria than both the heterosexual and nonheterosexual university students. Using a cut-point of 3.00, we found the sensitivity was 90.4% for the Gender identity patients and specificity was 99.7% for the controls. The utility of the GIDYQ-AA is discussed.

genetic link between Gender Dysphoria and sex hormone signaling
The Journal of Clinical Endocrinology and Metabolism, 2019Co-Authors: Madeleine Foreman, Lauren M Hare, Kate York, Kara Balakrishnan, Francisco J Sanchez, Fintan Harte, Jaco Erasmus, Eric Vilain, Vincent R HarleyAbstract:Context There is a likely genetic component to Gender Dysphoria, but association study data have been equivocal. Objective We explored the specific hypothesis that Gender Dysphoria in transGender women is associated with variants in sex hormone-signaling genes responsible for undermasculinization and/or feminization. Design Subject-control analysis included 380 transGender women and 344 control male subjects. Associations and interactions were investigated between functional variants in 12 sex hormone-signaling genes and Gender Dysphoria in transGender women. Setting Patients were recruited from the Monash Gender Clinic, Monash Health, Melbourne, Australia, and the University of California, Los Angeles. Patients Caucasian (non-Latino) transGender women were recruited who received a diagnosis of transsexualism [Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV) or Gender Dysphoria (DSM-V)] pre- or postoperatively. Most were receiving hormone treatment at the time of recruitment. Main Outcome Measured Genomic DNA was genotyped for repeat length polymorphisms or single nucleotide polymorphisms. Results A significant association was identified between Gender Dysphoria and ERα, SRD5A2, and STS alleles, as well as ERα and SULT2A1 genotypes. Several allele combinations were also overrepresented in transGender women, most involving AR (namely, AR-ERβ, AR-PGR, AR-COMT, CYP17-SRD5A2). Overrepresented alleles and genotypes are proposed to undermasculinize/feminize on the basis of their reported effects in other disease contexts. Conclusion Gender Dysphoria may have an oligogenic component, with several genes involved in sex hormone-signaling contributing.

Development and validation of a measure for assessing Gender Dysphoria in adults: The Gender Preoccupation and Stability Questionnaire
International Journal of Transgenderism, 2016Co-Authors: Az Hakeem, Fintan Harte, Rudi Črnčec, Mona Asghari-fard, Valsamma EapenAbstract:ABSTRACTAvailable clinically useful questionnaires for people with Gender Dysphoria incorporate outdated binary male/female Gender stereotypes. Moreover, no tools assess for Gender Dysphoria, a construct applicable to a Gender-diverse population. This study's purpose was to develop and validate an instrument that overcame these shortcomings: the Gender Preoccupation and Stability Questionnaire (GPSQ). Method: The 14-item GPSQ was developed through consultation with patients with Gender Dysphoria and experts in the field. The scale was administered to three groups of participants: those seeking treatment for Gender Dysphoria and Control Groups 1 and 2 with no Gender Dysphoria.Participants were also administered the Gender Dysphoria questionnaire (a 27-item scale wherein Gender Dysphoria was based on a bipolar dichotomous identity, which is at one pole male and at the other pole female, with varying degrees of Gender Dysphoria existing between them). Results: The GPSQ showed acceptable internal consistency ...

Assessing patient satisfaction with a multidisciplinary Gender Dysphoria clinic in Melbourne
Australasian psychiatry : bulletin of Royal Australian and New Zealand College of Psychiatrists, 2015Co-Authors: Jaco Erasmus, Harjit Bagga, Fintan HarteAbstract:Objectives:The Gender Dysphoria Clinic in Melbourne, Australia, assessed patient outcome by focusing on patients’ subjective evaluation of the healthcare services they received through the clinic.Methods:A satisfaction survey, which was previously used in two established Gender clinics in the US and UK, was adapted and then administered to consecutive patients who attended the Gender Dysphoria Clinic during a 1-month period.Results:A total of 127 surveys were available for analysis: 88% of patients reported being satisfied with the services they received. Patients’ perceived level of distress reduced significantly, following their involvement with the Gender Dysphoria Clinic. Feeling understood and heard in a non-judgmental manner by a specialist in the field of Gender Dysphoria was the most positive aspect of service provision. The most negative aspect of the clinic was a lengthy waiting list.Conclusions:Although the majority of trans-and-Gender-diverse patients attending the Gender Dysphoria Clinic were...
