Cognitive Remediation Therapy for Adolescents With Anorexia Nervosa

Not Applicable

Completed

• Conditions: Anorexia Nervosa
• Interventions: Behavioral: CRT + Teach the Parent; Behavioral: CRT + Contact Control

• Registration Number: NCT02883413
• Lead Sponsor: Children's Hospital of Philadelphia

Brief Summary

The purpose of the current study is to investigate the role of Cognitive Remediation Therapy (CRT) as a pre-treatment intervention for adolescents who are hospitalized for Anorexia Nervosa (AN). The primary aims are to determine if CRT can result in greater treatment engagement post-discharge, increased rate of weight gain post-discharge, reduction in symptom accommodation, and increased behavioral flexibility in adolescents and parents.

Detailed Description

Anorexia Nervosa (AN) is a severe psychiatric condition; the hallmark features are low body weight and difficulties gaining weight. We are in need of new methods to jump start treatment, while targeting relevant processes in individuals with AN.

Study Design:

This is a randomized controlled trial looking to address these concerns, with a focus on three distinct aims:

1. To evaluate the feasibility and acceptability (by patients and staff) of CRT in a medical hospitalization setting.

2. Compare the impact of CRT to CRT + Teach the Parent on adolescent treatment engagement post-discharge, rate of weight gain post-discharge, and reduction of symptom accommodation.

3. To evaluate cognitive and behavioral flexibility 6 months post-discharge.

Setting/Participants:

Participants will be 60 adolescents with AN or subclinical AN (and their parents). Adolescents will be hospitalized for treatment of AN and intervention will occur on an inpatient basis. Follow-up will be outpatient.

Study Interventions and Measures:

The current study will investigate the impact of intensive CRT (one sessions/day) delivered during in hospital for medical stabilization. Shortly after admission to hospital, adolescents will be randomly assigned to one of the following conditions: Treatment as usual (TAU), CRT+Contact Control (known as "Family Fun Time" or FFT) and CRT + Teach the Parent. Psychosocial, neurocognitive, and behavioral measures will be collected throughout the study. Follow-up will continue for 6 months post-discharge.

Description of Investigational Intervention:

CRT is an adjunctive intervention focusing on the development of meta-cognition: Teaching individuals to think about how they think. It involves presenting individuals with a variety of tasks requiring increasingly complex mental abilities. These include sorting tasks where rules change, geometric figures, illusions, reversing sequences of numbers and letters, and finding various routes on a map.

CRT's focus is mainly on process, instead outcome, and has three main goals:

1. Improve brain function by exercising and increasing connections in the brain

2. Encourage individuals to think about their thinking style

3. Encourage individuals and families to spend time away from thinking about the eating disorder

Arm && Interventions

Group	Intervention	Description
CRT +Teach the Parent	CRT + Teach the Parent	The Teach the Parent (TtP) addition to CRT is designed to increase parental understanding of their adolescents' thinking styles. We hypothesize that by doing so, parents will be more likely to challenge eating disorder behaviors and be less likely to accommodate behavioral symptoms of the eating disorder (e.g., make something low-fat for dinner because it will be easier). In this arm, adolescents will explain what they learned during CRT and walk their parents though at least 4 tasks during each TtP session. Parents and child will not be permitted to speak about the eating disorder during these sessions. TtP sessions will occur 3-4 times during hospitalization and will be guided by the adolescent.
CRT + Family Fun Time	CRT + Contact Control	In order to assess for any non-specific effects of spending non-eating disorder driven time with family, adolescents in the CRT+ Contact Control condition will be asked to spend 3-4 sessions with their parents engaging in fun activities (games, coloring, trivia). We refer to this condition as CRT + Family Fun Time (CRT+FFT). Adolescents will be asked to complete a series of fun tasks (some standardized, some are choice driven) with their parents. During these sessions, they will not be permitted to discuss CRT or the eating disorder.

Primary Outcome Measures

Name	Time	Method
Change in adolescent treatment engagement via questionnaire	Baseline to 3 months post baseline	The Motivational Stages of Change for Adolescents Recovering from an Eating Disorder (MSCARED) is a questionnaire designed to assess readiness to change among individuals with eating disorders. It is administered via interview, discussing motivation, actions that qualify for making changes, and asking what stage of change the patient is in. The patient then checks off those actions they are doing that contribute to their recovery from a provided checklist.

Secondary Outcome Measures

Name	Time	Method
Change in adolescent cognitive flexibility via questionnaire	Baseline to 6 months post baseline	The Cognitive Flexibility Scale (CFS) is a 12-item self report measure that assesses 3 different components: cognitive flexibility, rigidity and communication flexibility. Scores for each question range from 1-6 (strongly disagree - strongly agree). Scores on cognitive flexibility are positively related to communication flexibility and negatively related to rigidity. Scores on communication flexibility are also negatively related to rigidity.
Change in parental symptom accommodation, via questionnaire	Baseline to 3 months post baseline	The Accommodation and Enabling Scale for Eating Disorders (AESED) is a 39-item measure that gathers information about the enabling behaviors that family members with a child who has an eating disorder engage in. It contains three subscales: avoidance and modifying routine, meal ritual, and control of the family.
