Mentalization-enhancing therapeutic interventions in the psychotherapy of anorexia nervosa: An analysis of use and influence on patients' mentalizing capacity.

OBJECTIVE: Improvement in patients' mentalizing capacities is considered a possible mechanism of change in psychotherapy. This improvement might take place via mentalization-enhancing interventions (MEIs) performed by psychotherapists. The study aimed to explore the use of MEIs in two evidence-based psychotherapeutic treatments for patients with anorexia nervosa (enhanced cognitive-behavior therapy, focal psychodynamic therapy) and their association with the patients' capacity to mentalize in sessions ("in-session reflective functioning" / in-session RF). Additionally, it was explored, if the amount of MEIs used could either predict change in in-session RF or outcome (end of treatment, one year follow-up). METHOD: 84 audiotapes from psychotherapy sessions of 28 patients of the ANTOP-study (three sessions per patient) were transcribed and rated with both the MEI Rating Scale and the In-Session RF Scale by trained raters. RESULTS: MEIs were applied in both treatments. A moderate correlation between the amount of MEIs and patients' in-session RF as well as its change over the course of treatment was found, but no relation to change in BMI or eating disorder symptoms. CONCLUSION: A greater use of MEIs was related to patients' in-session-mentalizing. However, there seems to be no simple relation between RF as shown in sessions and symptom change.

Implementation of mentalization-based treatment in a day hospital program for eating disorders-A pilot study.

OBJECTIVE: Aim of the pilot study was to evaluate the effectiveness of a day hospital program for eating disorders (EDs) after implementation of mentalization-based treatment (MBT), including a comparison to a historical matched control group. METHOD: All consecutively admitted patients with an ED were included in a prospective, observational study over a period of 2 years. Main outcome criteria were eating and overall psychopathology. Furthermore, changes in the capacity to mentalize (reflective functioning [RF]), difficulties with affect regulation and interpersonal problems were assessed at admission, discharge and a three months follow-up. RESULTS: Thirty-eight out of fourty patients could be included. The program led to significant reductions in eating and general pathology. There was significant improvement in RF, difficulties in emotion regulation and interpersonal functioning. However, there was no advantage in comparison to a matched control group (main outcomes). ED symptoms showed a slight renewed increase after discharge, while body mass index further increased. RF change was predictive of change in overall psychopathology, but not ED symptoms. Drop-out rate was 13.2%. CONCLUSION: The program showed no advantage in comparison to a historical control group concerning a reduction in eating and overall psychopathology. However, it was associated with low drop-out rates, and changes which MBT targets: An increase in RF and a reduction of interpersonal problems as well as difficulties in emotion regulation.
