Relationship of maternal report of feminine behaviors and extraversion to clinician's rating of gender disturbance.

50 boys, aged 3 to 16 yr., referred for psychotherapy for a gender-identity disorder were assessed by two parent-report instruments completed by their mothers--The Gender Behavior Inventory for Boys for preadolescent subjects and a modified form of the Parents' Evaluation of Child Behavior. Without access to these data, an independent clinical psychologist provided a diagnosis of the severity of a gender disturbance on a 5-point rating scale, based on clinical interviews and a psychological test battery. The gender-disturbed boys scored significantly above the mean of the standardized normal boys on the Gender Behavior Inventory for Boys Feminine Behavior subscale and significantly below the mean on the Extraversion subscale of the Gender Behavior Inventory. The ratings of severity of gender disturbance were significantly correlated .34 with Feminine Behavior subscale scores and -.50 with the Extraversion subscale scores. On the Parents' Evaluation the number of observed feminine behaviors listed was significantly correlated .57 with rated severity of gender disturbance but not with the Feminine Behavior subscale scores on the Gender Behavior Inventory.
