ABSTRACT
The debate surrounding the inclusion of gender dysphoria/gender variant behavior (GD/GV) as a psychiatric diagnosis exposes many of the fundamental shortcomings and inconsistencies of our current diagnostic classification system. Proposals raised by the authors of this special issue, including basing diagnosis on cause rather than overt behavior, reclassifying GD/GV behavior as a physical rather than mental condition, and basing diagnosis on impairment or distress, offer some solutions but have limitations themselves given the available database. In contrast to most accepted psychiatric conditions where emphasis is placed on ultimately changing internal thoughts, feelings, and behaviors, consensus treatment for most GD/GV individuals, at least from adolescence onward, focuses on modifying the external body and external environment to maximize positive outcomes. This series of articles illustrating the diversity of opinions on when and if gender incongruence should be considered pathological reflects the relative lack of scientific indicators of disease in this area, similar to many other domains of mental functioning.
