Diagnosing Gender Dysphoria

The diagnosis of gender dysphoria is made by a psychologist or psychiatrist based on self-reporting and clinical judgment, assessed against the criteria of the DSM-5 or ICD-11. There is no biomarker, no objective test, and no measurable biological substrate. The diagnosis is therefore fundamentally different from, for example, a diagnosis of diabetes or cancer: it is based on what someone says about their own inner experience, interpreted by a clinician.

Who makes the diagnosis?

In the official Dutch pathway, the diagnosis is made by a licensed healthcare psychologist or psychiatrist at a specialized gender team (Amsterdam UMC, Radboudumc). Outside these centers, independent psychologists and commercial clinics also make the diagnosis, with widely varying levels of quality and care. At some informed-consent providers, the diagnostic assessment is limited to just a few sessions — sometimes only one — before hormones are prescribed. How the diagnostic phase works in practice is explained step by step on gendermolen.nl.

What should be assessed

A responsible diagnostic assessment looks not only at a person's gender experience, but also at:

• the duration and stability of the gender-related concerns (present since early childhood or only recently emerging during adolescence?);
• comorbid psychiatric problems — autistic traits, depression, anxiety disorders, trauma, eating disorders, personality problems, dissociation. These occur in a significant proportion of referrals;
• the social and family context: the influence of peers, social media, online communities, and any unwanted sexual experiences;
• sexual development and orientation — a gay or bisexual orientation in an unsafe environment can shape gender-related concerns;
• expectations surrounding transition and a realistic understanding of what hormones and surgery can and cannot provide.

How it often works in practice

Over the past ten years, diagnostic assessment in the Netherlands has gradually become narrower. Under pressure from waiting lists, rising demand, and activist criticism of "gatekeeping," the number of sessions has declined and the emphasis has shifted toward affirming self-reported identity. This is particularly evident among adolescents: the number of young people — especially teenage girls — seeking help has increased explosively since around 2010, a pattern that does not fit a stable biological phenomenon but points to considerable social influence.

Subjectivity and inter-rater reliability

Two clinicians who see the same patient may reach different conclusions. This is inherent to a diagnosis based on self-reporting and clinical judgment without objective reference points. For a condition whose treatment is irreversible — loss of fertility, physical changes, surgery — this diagnostic uncertainty is a serious problem that is rarely made explicit in information intended for the general public. German insurance data also show that the diagnosis in young people is not very stable.

DSM-5 versus ICD-11

The DSM-5 requires clinically significant distress for at least six months. The ICD-11 removes the distress criterion and refers instead to "gender incongruence." In practice, the DSM-5 is still predominantly used in the Netherlands because of the reimbursement system. See also DSM-5 and gender dysphoria and ICD-11 and gender variance.

International review

The Cass Review (2024) concluded that diagnostic assessment in gender clinics for young people was of insufficient quality, that comorbid problems were systematically overlooked, and that the diagnostic process led to medical interventions too quickly. Sweden, Finland, and Norway have fundamentally changed their practices and are once again emphasizing psychological assessment as the primary intervention. The Netherlands — once the birthplace of the Dutch Protocol — is lagging behind this shift. See also Dutch Protocol and Critical perspectives.

Rapid-onset gender dysphoria

The sharp increase in teenage girls with sudden gender-related concerns — often within friendship groups and frequently after intensive social media use — has led to the concept of "rapid-onset gender dysphoria" (Littman, 2018). The concept has been strongly challenged by activist groups, but the epidemiological data on the shift in the population seeking help are undeniable and call for diagnostic care, not dogmatic affirmation.
