Epidemiology of Gender Identity Disorder: Recommendations for the Standards of Care of the World Professional Association for Transgender Health
ABSTRACT Formal epidemiological studies on the incidence and prevalence of gender identity disorder (GID) or transsexualism have not been conducted. Accordingly, crude estimates of prevalence have had to rely on indirect methods, such as parental endorsement of behavioral items pertaining to GID on omnibus questionnaires for children and youth or the number of adult patients seeking contra-sex hormonal treatment or sex-transformative surgery at hospital- or university-based gender clinics. Data from child and adolescent parent-report questionnaires show that the frequent wish to be of the other sex is quite low but that periodic cross-gender behavior is more common. In the general population, cross-gender behavior is more common in girls than it is in boys but boys are referred to gender identity clinics more frequently than are girls. Prevalence estimates of GID in adults indicate that it is higher in natal males than in natal females although this may be accounted for by between-sex variation in sexual orientation subtypes. Prevalence estimates of GID in adults based on clinic-referred samples suggest an increase in more recent cohorts. It remains unclear whether this represents a true increase in prevalence or simply greater comfort in the seeking out of clinical care as professionals become more attuned to the psychosocial and biomedical needs of transgendered people.

ABSTRACT: This paper reviews the literature exploring gender differences associated with the clinical presentation of autism spectrum disorders (ASD). The potentially mediating effect of comorbid psychopathology, biological and neurodevelopmental implications on these gender differences is also discussed. A vastly heterogeneous condition, while females on the lower-functioning end of the spectrum appear to be more severely affected, an altered clinical manifestation of the disorder among high-functioning females may consequently result in many being un or misdiagnosed. To date, there is strong bias in the literature towards the clinical presentation of ASD in males. It is imperative that future research explores gender differences across the autism spectrum, in order to improve researchers', clinicians' and the publics' understanding of this debilitating disorder.Journal of Autism and Developmental Disorders 03/2013; · 3.06 Impact Factor

ABSTRACT: Both the diagnosis and treatment of Gender Identity Disorder (GID) are controversial. Although linked, they are separate issues and the DSM does not evaluate treatments. The Board of Trustees (BOT) of the American Psychiatric Association (APA), therefore, formed a Task Force charged to perform a critical review of the literature on the treatment of GID at different ages, to assess the quality of evidence pertaining to treatment, and to prepare a report that included an opinion as to whether or not sufficient credible literature exists for development of treatment recommendations by the APA. The literature on treatment of gender dysphoria in individuals with disorders of sex development was also assessed. The completed report was accepted by the BOT on September 11, 2011. The quality of evidence pertaining to most aspects of treatment in all subgroups was determined to be low; however, areas of broad clinical consensus were identified and were deemed sufficient to support recommendations for treatment in all subgroups. With subjective improvement as the primary outcome measure, current evidence was judged sufficient to support recommendations for adults in the form of an evidence-based APA Practice Guideline with gaps in the empirical data supplemented by clinical consensus. The report recommends that the APA take steps beyond drafting treatment recommendations. These include issuing position statements to clarify the APA's position regarding the medical necessity of treatments for GID, the ethical bounds of treatments of gender variant minors, and the rights of persons of any age who are gender variant, transgender or transsexual.Archives of Sexual Behavior 06/2012; 41(4):759-96. · 3.53 Impact Factor
