“…To date, adolescent CRT case studies-and series have supported the feasibility and acceptability of the intervention, both when delivered individually [53,55] in groups [67] and in families [65]. However, as all current RCTs are oriented towards adult patients, we still know little about the intervention's potential in terms of efficacy in younger AN populations.…”

“…One study had included patients with a current diagnosis of AN plus recently recovered AN patients (N = non specified) [52], and another study had included both current AN (N = 17) patients as well as participants with an eating disorder not otherwise specified (EDNOS) diagnosis (N = 7) [53]. Three of the 21 publications were based on the same sample [54][55][56]. The authors are not aware of additional sample overlaps.…”

“…In 2013, the second paper exploring CRT for adolescents with AN was published. This time, the format of delivery had changed, and the 20 patients in the Dahlgren et al study [55] received individually delivered CRT, tailored to meet each patient's specific needs. This was the first study to use materials developed specifically for children and adolescents [68].…”

Objective: To systematically review studies of cognitive remediation therapy (CRT) for anorexia nervosa (AN), and to discuss findings with references to clinical practice and future research. Method:The literature was reviewed using the PubMed, Web of Science and PsycINFO search terms "cognitive remediation therapy" AND "anorexia nervosa". Papers published online between 2005 and 2013 were selected on the basis of three inclusion criteria: 1) studies of any design focusing on CRT for AN, 2) papers that were written in English or had an available published English translation, and 3) papers published in peer reviewed journals.Results: A total of 45 papers were identified of which 21 were recognized as being relevant for the review. Relevant papers were divided into three different categories 1) single case reports, 2) case series and 3) randomised controlled trials (RCTs). Single case studies and case series yielded strong evidence of feasibility and acceptability of CRT for AN despite great variety in sample compositions. Four RCTs demonstrate that CRT has the potential of enhancing the effectiveness of current treatments, reduce attrition, increase cognitive set-shifting abilities and quality of life, as well as reduce eating disorder psychopathology. Discussion: The number of CRT studies published is growing rapidly, in particular RCTs. Further research is needed to define the primary aim of delivering CRT to patients with eating disorders, and to establish how to best measure the effect of the intervention. Moreover, researchers and clinicians should focus on identifying and assessing specific versus non-specific CRT contributions, and explore long-term effects of the intervention. It is imperative that adolescent RCTs are conducted to evaluate how CRT may be effective as a treatment for this young patient group.

Objective The aim of this randomized controlled trial with a parallel design was to evaluate the effect of brief, cognitive remediation therapy (CRT) for anorexia nervosa (AN) on set‐shifting. Method Two hundred seventy‐five inpatient adults and adolescents with AN (mean age = 23.1; SD = 12.7) were randomly assigned (using simple randomization procedures) to either a CRT or control condition. All participants received treatment as usual; however, the CRT condition completed five CRT group sessions in lieu of other group therapies provided on the unit. Set‐shifting abilities were evaluated by: (a) neuropsychological measures and (b) experimental cognitive behavior therapy thought records. Blinding of group assignment occurred during baseline assessment and ended following group commencement. Results Data from 135 CRT and 140 control condition participants were analyzed. On all neuropsychological measures, results revealed no between group condition effects, but did show statistically significant time effects, with medium to large effect sizes. Thought record analysis revealed a significant condition by age interaction effect where adults in the CRT condition generated significantly more alternative thoughts and had stronger believability of alternative thoughts than children, a trend that was not found in the control condition. This yielded moderate to large effect sizes of.0.56 and 0.72, respectively. Discussion Based on traditional neuropsychological measures, these findings do not suggest a differential effect of CRT for AN in the format applied. However, results suggest that CRT may have some increased beneficial cognitive effect for adults, as compared to children, based on thought record analysis.
