Objective: Mexican and U.S. patients with anorexia nervosa or bulimia (complete and partial syndromes) were compared on severity and types of preoccupations and rituals related to eating disorders and the motivation to change.
Method: One hundred seventy-four patients who met DSM-IV criteria for anorexia nervosa, bulimia nervosa, or ED-NOS participated. Eighty-seven subjects entered treatment at the Instituto Nacional de Psiquiatría "Ramón de la Fuente" in Mexico City and were matched with 87 patients treated at the New York Presbyterian Hospital. Patients were interviewed with the Yale-Brown-Cornell Eating Disorder Scale (YBC-EDS) (English or Spanish version).
Results: All YBC-EDS scores were higher for the Mexican group, which also had a greater number of current preoccupations and rituals. U.S. and Mexican patients were quite similar in their endorsement of current preoccupations, but the Mexican group was more likely to have rituals in all checklist categories, and the rituals were more egosyntonic. More U.S. patients had received previous treatment for their eating disorder. A negative correlation was obtained between the amount of previous treatment and motivation to change the preoccupations and rituals (higher scores indicating lower motivation).
Discussion: Cultural factors may influence characteristics of eating disorders. The previous treatment experiences of the U.S. patients seemed to positively influence their motivation for further treatment.

Introduction: Psychological abuse continues to be the most frequently reported type of maltreatment among athletes leading to negative mental health such as low mood and self-esteem, increased anxiety, self-harm, and eating disorders. Preliminary evidence suggests athlete satisfaction can influence the perceived outcomes associated with psychological abuse. Despite its negative impacts on athletes, psychological abuse continues to be justified as a tool to enhance athletic performance.

While epidemiological evidence is mixed on whether these individuals are more likely to commit acts of violence than the general public, certain behavioral characteristics may make them more vulnerable to extremist ideations.

Objective: This review maps existing literature on the prevalence of autism and ADHD in adult patients with Bulimia Nervosa (BN) and Binge Eating Disorder (BED); patient and stakeholder perspectives on this comorbidity; clinical differences in this population; and potential treatment adaptations or adjunct therapies. This is with the aim to inform future research priorities to improve clinical practice.
Method: As pre-registered, and following PRISMA guidelines, six databases (Embase, MEDLINE via Ovid, PsycINFO, Web of Science, CENTRAL, and Scopus) were searched for studies regarding autism and/or ADHD (diagnosed, probable, or traits) in adult patients with BN or BED.
