Background:
Impaired mentalizing, i.e., difficulties in understanding oneself and others in terms of mental states, has been associated with the development of Anorexia Nervosa (AN), mainly among adults. However, few studies have addressed this question in clinical samples of adolescents with AN. Moreover, no study has explored mentalizing abilities among inpatient adolescents presenting with AN and Borderline Personality Disorder (BPD), despite their high comorbidity in a highly relevant age group.
Objective:
This study attempted, for the first time, to further examine differences in mentalizing abilities and to identify specific mentalizing impairments in different psychiatric inpatient groups and healthy adolescents.
Methods:
Using samples of female adolescents aged 12–17, comparison analyses were performed between psychiatric inpatient adolescents with AN (
Results:
Comparison analyses showed that patients with BPD and other psychiatric disorders evidenced higher levels of hypermentalizing compared to healthy adolescents. Hypermentalizing was also reported among inpatients with AN+BPD, although to a lesser extent. BPD and AN scores were positively correlated with hypermentalizing responses.
Conclusions:
Our results suggest that hypermentalizing is a specific mentalization impairment in inpatient adolescents, particularly with BPD and both AN+BPD. Further investigation into the efficacy of mentalization based treatments for adolescents with BPD and AN+BPD is recommended. Prospective studies are needed to assess mentalizing using experimental tasks among adolescents with AN, taking into account the potential influence of temporality and severity of the disorders’ symptoms.
