Three latent profile (LP) groups were identified in a sample of 401 youths that sought eating disorder treatment. LP1 is characterized by binge eating and purging while LP2 is characterized by excessive exercise and extreme eating disorder cognitions while LP3 is characterized by minimal eating disorder behaviors and cognitions.

Objective: Research suggests that subtyping adults with binge eating disorders by dietary restraint and negative affect predicts comorbid psychopathology, binge eating severity, and treatment outcome. Little research has explored the validity and clinical utility of subtyping youth along these dimensions. Method: Children (aged 8-18 years) reporting loss of control eating (n = 159) were characterized based upon measures of dietary restraint and negative affect using cluster analysis, and then compared regarding disordered eating attitudes and behaviors, and parent-reported behavior problems. Results: Robust subtypes characterized by dietary restraint (n = 114; 71.7%) and dietary restraint/high negative affect (n = 45: 28.3%) emerged. Compared to the former group, the dietary restraint/high negative affect subtype evidenced increased shape and weight concerns, more frequent binge eating episodes, and higher rates of parent-reported problems (all ps < 0.05). Conclusion: Similar to findings from the adult literature, the presence of negative affect may mark a more severe variant of loss of control eating in youth. Future research should explore the impact of dietary restraint/negative affect subtypes on psychiatric functioning, body weight, and treatment outcome.

A study to examine the kind of eating disorders not otherwise specified (EDNOS) among adolescents encountered during treatment at an outpatient eating disorder clinic is conducted. Results indicate that EDNOS is more predominant among adolescents seeking treatment for eating disorders.

The phenomenology of childhood and adolescent loss of control (LOC) eating is unknown. The authors interviewed 445 youths to assess aspects of aberrant eating. LOC was associated with eating forbidden food before the episode; eating when not hungry; eating alone; and experiencing secrecy, negative emotions, and a sense of 'numbing' while eating (ps < .01). Hierarchical cluster analysis revealed a subgroup, most of whom reported LOC eating. Cluster members reported having a trigger initiate episodes, eating while watching television, and having decreased awareness regarding the amount consumed. The authors conclude that aspects of LOC eating during youth are similar to aspects of adult episodes, but a youth-specific presentation may exist. Findings may provide an intervening point to prevent excessive weight gain and eating disorders. Keywords: binge eating, loss of control eating, children, adolescents

Preliminary research suggests that pediatric overweight is associated with increased eating disorder pathology, however, little is known about which overweight youth are most vulnerable to eating disorder pathology. We therefore investigated 122 overweight treatment-seeking youth to describe eating disorder pathology and mental health correlates, and to identify psychopathological constructs that may place overweight youth at increased risk for eating disorder pathology. Youth participated in a comprehensive assessment of eating disorders, mood and anxiety disorders, general psychopathology, and risk variables involving semi-structured clinical interviews and self- and parent-report questionnaires prior to the initiation of weight-loss treatment. Ten youth met criteria for an eating disorder, and over one-third endorsed recent binge eating. Eating disorder pathology was associated with depressive and anxious symptoms (p's Keywords: Pediatric overweight; Eating disorder; Binge eating; Structural equation modeling; Risk modeling

Nonverbal strategic memory was evaluated in anorexia nervosa (AN) patients using a method previously applied to obsessive-compulsive (OC) spectrum disorders (OCD), as there seem to be similarities between AN and OC spectrum disorders. The study findings in OCD and BDD are similar, indicating important shared neuropsychological features among AN and these OC spectrum disorders.

This study compares patients with restricting anorexia nervosa (ANR) to patients with binge/purge anorexia nervosa (ANBP) and concludes that ANR is a stage in anorexia nervosa and not a distinct subtype, as previously considered. Of 136 women involved in the study, 62% crossed over from ANR to ANBP within eight years of follow-up.

A study is conducted to examine the longitudinal connections within personality and substance abuse in eating disorders. Substance use confirms cross-sectional connections with personality and substance abuse and is a significant forecaster in women with eating disorders.

A classification approach is employed for the study and identification of the various personality subtypes in adolescents with eating disorders (EDs). The results demonstrate the presence of three different personality subtypes in adolescents that are characterized on the basis of the personality style.

An analysis explains the effect of a past diagnosis of anorexia nervosa (AN) on the course and outcome of bulimia nervosa (BN) among women. The results reveal that women with a history of AN are less likely to be recovered completely.
