Prospective Evaluation of Psychosocial Changes After Chest Reconstruction in Transmasculine and Non-Binary Youth

This study sought to prospectively examine the effects of gender-affirming chest reconstruction on gender congruence and chest dysphoria in transmasculine and nonbinary adolescents and young adults.

Individuals between the ages of 15-35 who were seeking gender-affirming chest surgery were enrolled as part of a broader, longitudinal study of transgender surgical experiences. Their chest dysphoria and gender congruence were measured at baseline, six months, and one year, using the Transgender Congruence and Chest Dysphoria scales. Repeated measures analysis of variance were used to detect differences in scores across assessment points. Where there were significant differences indicated, Tukey's honestly significant difference test was used to determine which differences in mean scores were significant between assessment points, as well as how results differed by demographic factors.

The analytical sample consisted of 153 individuals who had completed both the baseline and at least one follow-up assessment - 36 (24%) endorsing a nonbinary gender and 59 (38%) under the age of 18. Repeated measures analysis of variance indicated significant differences in gender congruence, appearance congruence, and chest dysphoria between at least two assessment points for the total sample and each subgroup (binary/non-binary and adult/minor). Honestly significant difference tests indicated no significant differences between the postoperative assessments by age or binary gender.

Gender-affirming chest reconstruction improves gender and appearance congruence and reduces chest dysphoria in both non-binary and binary populations of adolescents and young adults. These data support the need to improve access to gender-affirming chest reconstruction for adolescents and young adults and to remove legislative and other barriers to care.
