Gender-affirming care through the lens of abnormal illness behaviour and abnormal treatment behaviour

ObjectiveTo describe the increasing number and changing demographics of patients presenting with gender dysphoria and provide an account of patient- and clinician-related factors which may have contributed to these changes. The concept of abnormal illness behaviours introduced by Pilowsky, and its extension to the concept of abnormal treatment behaviours by Singh, provides a framework for understanding healthy and pathological interactions between gender dysphoria patients and their doctors.ConclusionsAbnormal illness behaviours driven by the reinforcing contingencies of gender-affirming care may explain, in part, the increasing number and changing demographics of gender dysphoria, as well as the increasing incidence of desistance and detransition. The under-diagnosis and under-treatment of mental health disorders by clinicians treating these patients are examples of abnormal treatment behaviours. Uncritical affirmation of patient reported gender identity appears likely to conceal unconscious motivations of some patients and clinicians, increasing the risks of harm to both.
