Shifting Perspectives: Enhancing Outcomes in Anorexia Nervosa With CRT
Study Details
Study Description
Brief Summary
Anorexia Nervosa is a serious life-threatening illness with a typical age of onset in adolescence; if not effectively treated, it has the potential to significantly impact adolescent development and quality of life. Research on executive functioning in anorexia nervosa indicates that it may be a viable target for intervention that could improve outcome. The current project focuses on determining whether or not the investigators can improve set-shifting in parents and affected adolescents in the hopes that improvements in set-shifting will, ultimately, improve outcome.

Detailed Description
This application seeks support for a phased project. In the initial (R61) 2-year phase, the investigators will establish that Cognitive Remediation Therapy (CRT) can increase set-shifting in parents of and/or adolescents with Anorexia Nervosa (AN). The second aim is to determine the appropriate dose needed to achieve positive change in set-shifting. Attaining this milestone would trigger support for three additional years (R33) to confirm target engagement and appropriate dose. The investigators will also evaluate whether or not adding CRT to Family Based Treatment (FBT) will improve outcome compared to FBT alone. Set-shifting (a type of executive functioning often referred to as cognitive flexibility) inefficiencies are hypothesized to be an endophenotype of AN and are, therefore, heritable. Cognitive flexibility can be impacted negatively by situational factors such as malnutrition, stress, and anxiety. It is likely that both adolescents (who are malnourished) and parents (who are under stress) experience significant state-based reduction in their cognitive flexibility during AN and its treatment. While cognitive flexibility can be increased through CRT, there is a significant gap in the knowledge about how to apply CRT to the treatment of adolescent AN, specifically concerning the most appropriate target for CRT: parents or adolescents? The majority of research on CRT with adolescents with AN are pilot and feasibility studies and target set-shifting in adolescents, not parents. The investigators hypothesize that targeting parents may be more impactful for adolescent outcome. First, the investigators must determine if an increase set-shifting via CRT is possible. In the initial R61 phase, the investigators propose to recruit and randomly assign 54 families who have a child with AN to FBT, FBT with parent-focused CRT, or FBT with adolescent-focused CRT. Target engagement will be assessed via neuro-psychological assessment and self-report of cognitive and behavioral flexibility. If the investigators meet these proposed milestones in the R61 phase, they will proceed to the R33 phase. It is possible that one (N = 72 families) or both (N = 93 families) CRT conditions will be examined in the R33 phase. The investigators will confirm the findings from the R61 phase (target engagement and dose of CRT). The investigators will also examine adolescent outcome in FBT alone versus FBT+(parent or adolescent) CRT. They will gather preliminary data on putative moderators and/or mediators across both phases in order to inform results. This phased R61/R33 application is innovative in that it is the first to adapt CRT to parents only. Evidence supporting FBT+CRT to increase set-shifting in parents/adolescents will inform future efforts to leverage understanding of (heritable) neurobiology of AN in adolescents to improve outcome. Further, if CRT for parents significantly improves set-shifting, the investigators can focus efforts on how best to augment current treatments, support parents, and increase positive outcomes for the adolescent and reduce relapse. Even negative results would inform understanding of set-shifting inefficiencies as an endophenotype in AN, its measurement, and usefulness as a target in treatment.

| Active Comparator: Family Based Treatment (FBT) Families will receive 15 sessions of FBT alone. |
Behavioral: Family Based Treatment
Family Based Treatment (FBT) is an evidence based treatment in which parents are responsible for adolescent re-nourishment. They play an active role in treatment and their self-efficacy to make decisions regarding their child's treatment is empowered.
Other Names:
|
| Experimental: FBT w/ Parent-focused Cognitive Remediation Therapy Family Based Treatment with Parent-focused Cognitive Remediation Therapy (CRT): Families will receive 15 sessions of parent focused CRT followed Family Based Treatment over six months. |
Behavioral: Cognitive Remediation Therapy
Cognitive Remediation Therapy (CRT) is an adjunctive treatment focused on increasing set-shifting ability and developing meta-cognition.

Outcome Measures
Primary Outcome Measures
- Change in executive functioning [Baseline to 7 months]
Investigators will use the Delis Kaplan Executive Functioning System (D-KEFS) Trails Number-Letter Sequencing subtest, a neurocognitive behavioral task, to assess ability to set-shift (a core component of executive functioning). Investigators will compare change in T scores from pre, during, and post-treatment across groups.
- Change in response inhibition [Baseline to 7 months]
Investigators will use the D-KEFS Inhibition subtest, neurocognitive behavioral task, to assess ability to inhibit automatic responses. Investigators will compare change in T scores from pre, during, and post-treatment across groups.
- Change in set shifting [Baseline to 7 months]
Also using the D-KEFS Inhibition task, investigators will use scores from the D-KEFS Inhibition/Switching subtest to assess ability to switch between alternating rules (a component of set shifting). Investigators will compare change in T scores from pre, during, and post-treatment across groups.
- Change in shifting accuracy [Baseline to 7 months]
Investigators will use the D-KEFS Verbal Fluency subtest, neurocognitive behavioral task, to assess accuracy in shifting categories (a component of executive functioning). Investigators will compare change in T scores from pre, during, and post-treatment across groups.
- Change in category switching flexibility [Baseline to 7 months]
Investigators will also use the D-KEFS Verbal Fluency subtest, category switching scores, to assess flexible switching (a component of executive functioning). Investigators will compare change in T scores from pre, during, and post-treatment across groups.
- Change in flexibility [Baseline to 7 months]
Investigators will use the D-KEFS Sorting subtest, neurocognitive behavioral task, to assess changes in flexibility. Investigators will compare change in T scores from pre, during, and post-treatment across groups.
- Change in self-reported executive functioning [Baseline to 7 months]
The Behavior Rating Inventory of Executive Functioning (BRIEF) is a self and parent-report measure of executive functioning. The measure comprises 10 clinical scales, of which investigators will use the subscales of Inhibition and Shifting. Investigators will compare change in T scores from pre, during, and post-treatment across groups.
- Dose of CRT [Baseline to 7 months]
Number of sessions necessary (session = subject receive dose of CRT) in order to change cognitive flexibility
