Interventions
Before starting treatment, participants should complete the Chest Dysphoria Measure and iTransQoL questionnaires (=time point 0). The second time point for completing the questionnaires again is 3 months after starting hormone therapy. Subsequently, the questionnaires should be completed a third time after breast-affirming surgery. The final survey takes place two years after time point 0, or 6 months after the previous survey.
