As well as supporting the results of previous studies by providing evidence of inefficient global processing, this review has provided evidence of superior local processing, which supports the WCC hypothesis in ED.
The inefficiencies in set shifting that are apparent in the adult AN literature do not appear to be as pronounced in children. This may suggest that set shifting difficulties in adult AN are the result of starvation or indicative of longer duration of illness. Larger studies are needed to confirm these impressions.
ObjectiveMany adolescents with obsessive-compulsive disorder (OCD) do not have access to evidence-based treatment. A randomized controlled non-inferiority trial was conducted in a specialist OCD clinic to evaluate the effectiveness of telephone cognitive-behavioral therapy (TCBT) for adolescents with OCD compared to standard clinic-based, face-to-face CBT.MethodSeventy-two adolescents, aged 11 through 18 years with primary OCD, and their parents were randomized to receive specialist TCBT or CBT. The intervention provided differed only in the method of treatment delivery. All participants received up to 14 sessions of CBT, incorporating exposure with response prevention (E/RP), provided by experienced therapists. The primary outcome measure was the Children’s Yale–Brown Obsessive-Compulsive Scale (CY-BOCS). Blind assessor ratings were obtained at midtreatment, posttreatment, 3-month, 6-month, and 12-month follow-up.ResultsIntent-to-treat analyses indicated that TCBT was not inferior to face-to-face CBT at posttreatment, 3-month, and 6-month follow-up. At 12-month follow-up, there were no significant between-group differences on the CY-BOCS, but the confidence intervals exceeded the non-inferiority threshold. All secondary measures confirmed non-inferiority at all assessment points. Improvements made during treatment were maintained through to 12-month follow-up. Participants in each condition reported high levels of satisfaction with the intervention received.ConclusionTCBT is an effective treatment and is not inferior to standard clinic-based CBT, at least in the midterm. This approach provides a means of making a specialized treatment more accessible to many adolescents with OCD.

ObjectiveThis study aimed to examine neuropsychological processing in children and adolescents with Anorexia Nervosa (AN). The relationship of clinical and demographic variables to neuropsychological functioning within the AN group was also explored.MethodThe performance of 41 children and adolescents with a diagnosis of AN were compared to 43 healthy control (HC) participants on a number of neuropsychological measures.ResultsThere were no differences in IQ between AN and HC groups. However, children and adolescents with AN displayed significantly more perseverative errors on the Wisconsin Card Sorting Test, and lower Style and Central Coherence scores on the Rey Osterrieth Complex Figure Test relative to HCs.ConclusionInefficient cognitive processing in the AN group was independent of clinical and demographic variables, suggesting it might represent an underlying trait for AN. The implications of these findings are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
