What Is Sexual Orientation and Gender Identity Disorder?

Sexual Orientation and Gender Identity Disturbance/Disorder (SOCD) is a historical concept used in psychiatry to classify distress related to a person’s sexual orientation or gender identity. This term represents a period when major medical organizations viewed non-heterosexual and non-cisgender identities as forms of mental illness. Today, scientific and medical consensus holds that sexual orientation and gender identity are natural variations of human experience and are not disorders. This shift reflects an evolution in understanding, moving from pathologizing identity to recognizing that societal stigma causes distress.

Historical Origins and Diagnostic Context

The pathologizing of non-heterosexual identity began with its inclusion in early diagnostic manuals. In 1952, the first edition of the American Psychiatric Association’s Diagnostic and Statistical Manual (DSM-I) classified homosexuality under “sociopathic personality disturbance.” This classification framed a same-sex orientation as a deviation from expected social norms and healthy psychological development.

This initial classification was revised in the DSM-II (1968) to “sexual deviation,” grouping it with other atypical behaviors. The diagnosis focused on the identity itself as the problem, reflecting a scientifically unsupported view. This perspective justified treatments aimed at changing a person’s orientation, which are now discredited.

Following intense advocacy, the diagnosis of homosexuality was partially removed in 1973. It was replaced with a concept that pathologized the distress surrounding the identity, leading to “Ego-Dystonic Homosexuality” (EDH) in the DSM-III (1980). EDH required the individual to experience persistent, unwanted same-sex arousal and a desire to change their orientation. Gender-related pathology also appeared in the DSM-III as “Gender Identity Disorder” (GID), classifying incongruence between assigned sex and experienced gender as a mental disorder.

The Process of Depathologization

The shift away from these classifications was driven by scientific research and social pressure. Studies showed that mental health challenges experienced by non-heterosexual individuals resulted from external factors like societal prejudice, discrimination, and internalized stigma. This understanding undermined the core assumption that the identity itself was the pathology.

The American Psychiatric Association responded to this evidence, officially removing the diagnosis of homosexuality in 1973. This decision marked the beginning of a gradual depathologization process. The specific diagnosis of Ego-Dystonic Homosexuality was removed from the DSM-III-R in 1987, replaced by a residual category noting “marked distress about one’s sexual orientation.”

A similar evolution occurred for gender-related diagnoses. In 2013, the DSM-5 replaced “Gender Identity Disorder” with “Gender Dysphoria.” This shifted the diagnostic focus away from the identity itself and onto the clinically significant distress caused by the incongruence between assigned sex and experienced gender. The World Health Organization removed its final category related to same-sex distress, “ego-dystonic sexual orientation,” in the 2019 revision to the ICD-11, deleting the F66 chapter that housed these historical classifications.

Current Clinical Understanding of Identity-Related Distress

When a patient presents with identity concerns today, the modern therapeutic approach differs fundamentally from the historical SOCD framework. The goal is to alleviate mental health distress, not to change the person’s sexual orientation or gender identity. For individuals experiencing distress related to identity-assigned sex incongruence, Gender Dysphoria is used to provide access to affirming medical interventions, such as hormone therapy or surgery.

For distress related to sexual orientation or identity concerns that do not meet Gender Dysphoria criteria, clinicians use non-identity-specific diagnoses. These often include general categories for anxiety, depression, or adjustment disorders. In the DSM-5, a clinician might use terms like “Other Specified Sexual Dysfunction” or “Unspecified Sexual Dysfunction” to capture distress related to sexual life without pathologizing orientation.

Therapy focuses on helping the patient navigate the social and psychological challenges associated with their identity, such as internalized stigma, family rejection, or social discrimination. The clinical intervention centers on affirmation and support, helping the individual develop a positive sense of self and cope with external adversity. This approach reflects the consensus that the problem lies in the conflict between the identity and an unaccepting environment, not within the identity itself.

Professional Consensus and Harmful Practices

Major medical and psychological organizations have established a unified professional consensus against any practice attempting to change a person’s sexual orientation or gender identity. The American Psychological Association (APA) and the Pan American Health Organization (PAHO/WHO) strongly oppose “conversion therapy” or “reparative therapy.” These practices are founded on the scientifically discredited assumption that diverse sexual orientations and gender identities are mental illnesses requiring a cure.

Research indicates that attempts to change an individual’s identity are ineffective and actively harmful, leading to significant mental health risks. Documented harms include increased anxiety, depression, self-harm, and suicidal ideation, particularly when practiced on minors. Consequently, ethical guidelines mandate that practitioners support clients in exploring and affirming their identities, rather than seeking to suppress or change them.

The consensus requires that ethical care be identity-affirming, helping individuals thrive as their authentic selves. The APA explicitly encourages psychotherapies that affirm a person’s sexual orientation and gender identity. This position is shared by numerous other professional bodies, recognizing that supportive, non-judgmental care is the standard for promoting the health and well-being of all individuals.
