Brief Summary

Eating disorders (ED) are severe but treatable conditions, but there are large margin for improvements in terms of efficacy and adherence. There is room to explore new treatment options who are either more capable to retain patients in therapy, more effective. Alternative their efficacy may match the ones of current available treatments but offer new options to ones that did not respond to available therapies. Here the investigators explored if a combination of CBT-focused plus Metacognitive Interpersonal Therapy (MIT) is an empirically supported therapy for personality disorders and could be a new viable treatment option for non-underweight ED. MIT targets some aspects of ED such as poor awareness of mental states and maladaptive interpersonal schemas that are not included in the transdiagnostic model underlying the most investigated empirically supported treatment for ED that is CBT-E. It is reasonable therefore that targeting these aspects of psychopathology can be a path to treatment adherence and effectiveness

Outcome Measures

Primary Outcomes (4)

• Eating Disorder Examination Questionnaire (EDE-Q6; Fairburn & Beglin, 1994)

  A self report measure assessing eating disorders over the past 4 weeks, providing a measure of the range of severity of eating disorder features.

  Change from baseline until after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

• Eating Attitude Test (EAT-26; Garner & Garfinkel, 1979)

  A self-report measure for identifying the presence of "eating disorder risk" based on attitudes, feelings and behaviors related to eating. It assesses general eating behaviour and risky behaviours.

  Change from baseline until after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

• Clinical Impairment Assessment Questionnaire (CIA 3.0; Bohn and Fairburn, 2008).

  a self-report measure f assessing the severity of psychosocial impairment due to eating disorder features over the past 28 days.

  Change from baseline until after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

• Binge Eating Scale (BES; Gormally et al., 1992)

  a self-report questionnaire of the behavioral, cognitive and emotional features of objective binge eating (OBE).

  Change from baseline until after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

Secondary Outcomes (7)

• State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983)

  At baseline, after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

• Beck Depression Inventory (BDI; Beck, et al., 1961)

  At baseline, after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

• Symptom Check List (SCL-90)

  At baseline, after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

• Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, 2004)

  At baseline, after 10 sessions, at the end of the treatment and in the following 3, 6, 12, 18 and 24 months after the treatment.

• Structured Clinical Interview for DSM-5 Disorders (SCID-5; Michael B. First, Janet B.W. Williams)

  At baseline

Study Arms (2)

CBT-E

ACTIVE COMPARATOR

Participants in the CBT-E condition will receive a total of 20 CBT-E sessions over 20 weeks. CBT-E treatment will consist of four stages. In particular, CBT aims to inform patients about the importance of self-control, the dangers of some restrictive behaviors such as self-induced vomiting. Moreover, CBT provides strategies to patients in order to monitor their usually dysfunctional behaviors and so increasing their awareness (i.e. food diary method) while reducing the availability of food and encourages activities that are incompatible with overeating. Patients will be trained in problem solving in order to change these feelings, as well as in increasing their self-awareness in order to recognize irrational thoughts about their body weight and shape. Additionally, they will be gradually exposed to foods that they had been avoiding.

Other: CBT-E

CBT-F+MIT

EXPERIMENTAL

Participants in the CBT-F+MIT condition will receive a total of 20 sessions over 20 weeks. Specifically, 2 sessions will be based on CBT-F as usual only. During these sessions participants will receive psychoeducational training on eating behaviors and an introduction to the protocol tools, namely the monitoring form, weight chart, transdiagnostic formulation and Eating Problem Check List (EPCL). These elements will be used at the beginning of the remaining 18 sessions, in order to monitor the regulations of eating behaviors as well eliciting narrative episodes. These materials will form the basis for the MIT-part of the session, in which therapists will seek to form with the patient a shared understanding of the psychological reasons underlying their ED symptoms and their maladaptive interpersonal functioning. MIT sessions will be integrated within the CBT-F protocol which will provide psycho-educational, nutritional re-education and management for ED.

Other: CBT-F+MIT

Interventions

CBT-F+MIT OTHER

The aim is to develop healthier strategies for managing negative thoughts and feelings antecedent to ED and for engaging patients in social interactions that meet their relational basic wishes. They will thus understand that perfectionism and the need for control they experience through ED are coping strategies developed within interpersonal patterns of interaction with significant others, where low self-esteem and emotive dysregulation play a central role. MIT aims to improve individuals' capacity to make sense of their own affect and cognitions and become aware of being driven by maladaptive, rigid and biased schemas about self and others, to form a richer understanding of the mind of the others and use this knowledge to react in more adaptive ways to social difficulties or evolutionary selected wishes. MIT also enables individuals to reflect on how these schemas may act as triggers for ED behavior and to develop more effective coping strategies in face of interpersonal stressors.

CBT-F+MIT

CBT-E OTHER

In the first Stage, the treatment will be focused on achieving a shared understanding of the patient's eating disorder and the related maintenance factors. In this phase the patient will be helped to regulate and stabilize his eating habits and so to address his weight concerns. In the second stage, progress made is reviewed in detail. In the third stage, the sessions will be focused on the central processes that are maintaining the psychopathology of the patient's eating disorder. In particular, this involves in addressing concerns about weight and body shape, cognitive and caloric dietary restriction, events and emotions that affect nutrition. In phase three and four clinical perfection, low global self-esteem, intolerance of emotions and interpersonal difficulties are also addressed. Towards the end of the third stage and during the fourth stage, procedures will be also implemented to minimize the risk of short- and long-term relapse.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: OUTCOMES ASSESSOR
• Masking Details: Each participant will be randomized in one of the two experimental conditions by allocation concealment. In particular, randomized-permuted blocks will be used. The research team will be also blind to the randomized allocation. Group allocation will remain concealed until the end of the assessment stage.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Psychotherapist

Model Details: A parallel-group randomized controlled trial design will be used in order to compare CBT-E (n = 10) condition to combined MIT/CBT-F (n = 10). Patients in both conditions will receive 20 weekly sessions of either CBT-E or CBT-F+MIT. Repeated follow-up will be collected up to 24 months. The study is run in an private outpatient clinic specialized in eating disorder treatment. We will evaluate acceptability in terms of session attendance and number of completers and preliminary outcomes.
