In contrast to this, a number of facts about Kraig have become public information, including: that he was a gay man; that according to his family, he never recovered from these treatments; and that in 2003, at the age of 38, he committed suicide. Even without confirmed knowledge of such outcomes, by the mid-1970s Rekers's publications on his treatment modality were already attracting harsh criticism from scholarly and popular media sources, and Bryant speculates that this is one possible explanation for why many clinicians do not publish on their treatment techniques, focusing instead on less controversial aspects of GD, such as diagnostic criteria. Therapeutic approaches for GD differ from those used on adults and have included behavior therapy, psychodynamic therapy, group therapy, and parent counseling. This includes aiming to reduce gender dysphoria, making children more comfortable with their bodies, lessening ostracism, and reducing the child's psychiatric comorbidity. Therapeutic intervention seeks to identify and resolve underlying factors (including familial factors), encourage the child to identify with their assigned sex, and encourage same-sex friendships. Parent counseling involves setting limits on the child's cross-gender behavior, encouraging gender-neutral or sex-typical activities, examining familial factors, and examining parental factors such as psychopathology. Researchers Zucker and Susan Bradley state that it has been found that boys with GD often have mothers who, to an extent, reinforced behavior more stereotypical of young girls. They also state that children with GD tend to come from families where cross-gender role behavior was not explicitly discouraged. However, they also acknowledge that one could view these findings as merely indicative of the fact that parents who were more accepting of their child's cross-gender role behavior are also more likely to bring their children to a clinical psychiatrist as opposed to parents who are less accepting of cross-gender role behavior in their children. In 2002, Zucker acknowledged limited data on gender dysphoria in children, stating that "apart from a series of intrasubject behaviour therapy case reports from the 1970s, one will find not a single randomized controlled treatment trial in the literature". He has stated that "the therapist must rely on the 'clinical wisdom' that has accumulated and to utilize largely untested case formulation conceptual models to inform treatment approaches and decisions." In 2018, in a narrative systemic review titled "Conversion therapies and access to transition-related healthcare in transgender people", Zucker's work was provided as a case study in conversion therapy including
