The prognoses for eating disorders are relatively poor, and a large part of patients with these illnesses do not benefit from available conventional therapies. After decades of research into the causes of eating disorders, there is now compelling evidence for specific neuropsychological difficulties in patients affected by eating disorders. These neuropsychological difficulties are characterized by cognitive and behavioral rigidity (poor set-shifting abilities), as well as difficulties related to central coherence, planning and impulse control. Surprisingly, few therapies specifically target these difficulties, and they are rarely incorporated into treatment. Cognitive Remediation Therapy has shown promising results as an adjunctive therapeutic intervention for patients with anorexia Nervosa. The primary aim of this randomized controlled trial is thus to investigate the effect of Cognitive Remediation Therapy on neuropsychological function, symptoms of eating disorders and general mental health, quality of life and motor activity in women with both eating disorders (transdiagnostic) and these specific cognitive difficulties.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '36 Years', 'minimumAge': '16 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Being in in-patient-, day- or out-patient treatment for an eating disorder (anorexia nervosa, bulimia nervosa, binge eating disorder or OSFED)\n* Displaying cognitive difficulties (score ≤ -1 standard deviation) on:\n\n 1. the Inhibit, Shift, Plan/ Organize and/ or Global Executive Composite indexes of the self-report measure the BRIEF-A (reversed)\n 2. the Total errors, Perseverative Responses, Perseverative Errors and/ or Learning to learn from the Wisconsin Card Sorting Test (WCST) and/ or on the Rey Complex Figure Test (RCFT) Copy condition or Q-score and/ or on condition 3 and 4 on the Color-word Interference Test from (D-KEFS)\n* Being able to understand and speak Norwegian\n* Be willing to provide written informed consent\n* Accepting random allocation to the two arms of the study\n\nExclusion Criteria:\n\n* A history of congenital or acquired brain injury (except concussions)\n* Active substance abuse\n* Psychosis\n* Intelligence quotient (IQ) less than 70'}, 'identificationModule': {'nctId': 'NCT03808467', 'acronym': 'TCRTRCT', 'briefTitle': 'Cognitive Training for Patients With Eating Disorders', 'organization': {'class': 'OTHER', 'fullName': 'Norwegian University of Science and Technology'}, 'officialTitle': 'Transdiagnostic Cognitive Remediation Therapy for Patients With Eating Disorders: a Randomized Controlled Trial', 'orgStudyIdInfo': {'id': '2018/1182'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'CRT + TAU', 'description': 'Cognitive Remediation Therapy + Treatment As Usual', 'interventionNames': ['Behavioral: Cognitive Remediation Therapy', 'Other: Treatment as usual']}, {'type': 'OTHER', 'label': 'TAU only', 'description': 'Treatment As Usual', 'interventionNames': ['Other: Treatment as usual']}], 'interventions': [{'name': 'Cognitive Remediation Therapy', 'type': 'BEHAVIORAL', 'otherNames': ['CRT'], 'description': 'Nine individual transdiagnostic CRT sessions will be delivered once per week, each session lasting approximately 45 minutes.
