Objective: International treatment guidelines recommend psychotherapy as the first-line treatment for anorexia nervosa (AN). Adaptation of Western evidence-based treatments to different cultures through personalization has become increasingly important, but evidence remains limited. This study examined the feasibility and effectiveness of AN outpatient psychotherapies in Korea. Methods: A total of 160 adult patients diagnosed with AN (mean age = 25.3 years) were recruited from an eating disorder (ED) clinic in Korea. They received one of the following psychotherapy programs: motivational enhancement therapy with nutrition (MET with nutrition) (n = 47); Maudsley Model of Anorexia Nervosa Treatment for Adults (MANTRA) augmented by New Maudsley Model for Collaborative Care (NMCC) (n = 20); or Specialist Supportive Clinical Management (SSCM) (n = 93). Treatments were administered face-to-face by trained therapists, following protocols tailored to each individual. Demographic and ED‐related clinical data were collected through standardized interviews and questionnaires at baseline and at the end of treatment. Results: Overall dropout rate was 40.3%, with a lower rate observed in MANTRA augmented by NMCC and SSCM than MET with nutrition. All three psychotherapies increased body mass index (BMI), with minimal group differences.Individuals with lower baseline BMI and those who attended more sessions experienced greater BMI increases across all psychotherapies. Conclusion Psychotherapies for AN were feasible and showed promise in terms of effectiveness among Korean patients.Despite comparable BMI increases, the therapies led by experienced therapists and with greater personalization had lower dropout rates. Further studies using randomized controlled trials are needed while controlling for variables outside treatments.

OBJECTIVE: Oxytocin is a neuropeptide that is involved in social emotional processing. A leading hypothesis is that oxytocin facilitates positive prosocial behaviors; the peptide may also play a more general role in inhibiting withdrawal-related social behaviors. The present study examined these possibilities. METHODS: A double-blind, placebo controlled crossover design was used with 31 healthy women. Forty-five minutes following the administration of 40 IU of intranasal oxytocin or a placebo, the participants were presented with two dot probe tests with pairs of face stimuli depicting emotional and neutral faces in adults. RESULTS: Oxytocin specifically reduced the attention bias toward the location of the faces of adults showing negative emotions, particularly in the case of disgust. Oxytocin did not enhance the attentional bias toward adult happy faces. The effect of oxytocin toward adult negative emotion was correlated with the sensitivity of the drive in the behavioral motivational system. CONCLUSION: Oxytocin reduces attention to negative social emotions in adults, which supports oxytocin serves to inhibit withdrawal-related social behaviour.

OBJECTIVE: Although it is thought that eating disorders result from the interplay of personal and sociocultural factors, a comprehensive model of eating disorders remains to be established. The aim of this study was to determine the extent to which the childhood factors and deficit in visuoperceptual ability contribute to eating disorders. METHODS: A total of 76 participants - 22 women with anorexia nervosa (AN), 28 women with bulimia nervosa (BN), and 26 healthy women of comparable age, IQ, and years of education - were examined. Neuropsychological tasks were applied to measure the visuoperceptual deficits, viz. the Rey-Osterrieth complex figure test and the group embedded figures test (GEFT). A questionnaire designed to obtain retrospective assessments of the childhood risk factors was administered to the participants. RESULTS: The women with both AN and BN were less likely to report having supportive figures in their childhood and poor copy accuracy in the Rey-Osterrieth test. The women with AN were more likely to report premorbid anxiety, childhood emotional undereating and showed poor performances in the GEFT. In the final model, the factors independently contributing to the case status were less social support in childhood as a common factor for both AN and BN, and childhood emotional undereating and poor ability in the low-level visuospatial processing for AN. CONCLUSION: Our results suggest the disturbance in the food-emotion relationship and the deficit in low-level visuospatial processing in people with AN. Lower social support appears to contribute to an increase in vulnerability to both AN and BN.
