“…Cognitively, adolescents who are acutely ill may have difficulties in set-shifting (i.e., moving flexibly from one task to another), and tend to display weak central coherence (i.e., difficulties in seeing the whole picture as opposed to focusing on small details) (Allen et al, 2012). Both difficulties in set-shifting and weak central coherence can in turn contribute to a lack of behavioral flexibility (Treasure & Schmidt, 2013).…”

Family based-treatments have the most empirical support in the treatment of adolescent anorexia nervosa; yet, a significant percentage of adolescents and their families do not respond to manualized family based treatment (FBT). The aim of this open trial was to conduct a preliminary evaluation of an innovative family-based approach to the treatment of anorexia: Acceptance-based Separated Family Treatment (ASFT). Treatment was grounded in Acceptance and Commitment Therapy (ACT), delivered in a separated format, and included an ACT-informed skills program. Adolescents (ages 12–18) with anorexia or sub-threshold anorexia and their families received 20 treatment sessions over 24 weeks. Outcome indices included eating disorder symptomatology reported by the parent and adolescent, percentage of expected body weight achieved, and changes in psychological acceptance/avoidance. Half of the adolescents (48.0%) met criteria for full remission at the end of treatment, 29.8% met criteria for partial remission, and 21.3% did not improve. Overall, adolescents had a significant reduction in eating disorder symptoms and reached expected body weight. Treatment resulted in changes in psychological acceptance in the expected direction for both parents and adolescents. This open trial provides preliminary evidence for the feasibility, acceptability, and efficacy of ASFT for adolescents with anorexia. Directions for future research are discussed.

Objectives: It is hypothesised that Weak Central Coherence (superior attention to detail with poorer bigger picture thinking) is a possible endophenotype for Anorexia Nervosa (AN). Currently the neuropsychological profile of children and adolescents with AN in unclear. The present review aimed to summarise the available literature with regards to the central coherence abilities of children and adolescents with AN, and clarify their neuropsychological profile.Method: The search found seven eligible studies. Meta-analyses were not possible due the variation in tasks used.Results: Evidence of less efficient global processing in children with AN was observed in a number of studies. The strongest evidence was observed from studies using the Rey Osterrieth Complex Figures Test (ROCFT). A visual comparison of ROCFT from child and adult AN studies highlighted similarities in global processing profiles. Conclusions:Evidence of inefficient global processing was observed across a number of studies. However methodological flaws in the current literature were highlighted and made interpretation difficult. These are discussed and recommendations for future research are made.

“…Binge eating, which involves consuming an objectively large amount of food while experiencing a sense of loss of control while eating, 19 is associated with both obesity 20 and poorer executive functioning 11,12 and may be one potential pathway to elevated weight status among those with pre-existing executive function difficulties. Children reporting binge eating behaviors frequently present with concomitant obesity in cross-sectional studies, 20 and also are at risk for excess gains in weight and body fat over time.…”

Objective Executive functioning and excess weight have been associated in both cross-sectional and prospective studies, but mechanisms explaining this relationship are unclear. The current study aimed to further explore the longitudinal relationship between executive functioning and changes in body weight, and to determine whether binge eating behaviors mediate this relationship. Methods Community-based girls (N=2,450) were assessed using the WISC-III Mazes subtest and a parent-report measure of impulsivity at age 10, and using a self-report measure of binge eating and investigator-measured body mass index (BMI; kg/m2) annually between ages 10–16. Regression and bootstrapping analyses explored the relations among age 10 impulsivity and Mazes performance, age 12 and age 14 binge eating frequency, and age 10–16 BMI changes. Results Age 10 impulsivity and Mazes performance each independently predicted age 10–16 BMI changes, after accounting for demographics, verbal comprehension, and BMI at age 10 (ps<.001). Binge eating tendencies at age 12 mediated the relation between age 10 impulsivity and age 10–16 BMI changes, after controlling for demographics, verbal comprehension, binge eating frequency, and BMI at age 10 (indirect effect estimate=.0007; 95% CI=0.0001–0.0020). Discussion Results support the hypothesis that poorer executive functioning predicts weight gain from middle childhood through adolescence in girls, and that this effect may be partially explained by binge eating behaviors in early adolescence.
