Validating the Stirling Eating Disorders Scales (SEDS) in an adolescent population.

OBJECTIVE: This study aimed to determine the validity and utility of the Stirling Eating Disorder Scales (SEDS) as a screening instrument for eating disorders in adolescents. METHOD: A total of 53 patients and 61 age-matched controls all completed the SEDS, and patients completed the Eating Disorders Examination (EDE) for construct comparison purposes. RESULTS: The SEDS was found to have good criterion and discriminant validity, as well as high internal consistency. DISCUSSION: The SEDS appears to be useful as a screening tool for adolescents, although many participants had some difficulties with comprehending certain items, which may affect its utility in young populations.

Dissociation in adolescent girls with anorexia: relationship to comorbid psychopathology.

This study investigated the relationship between dissociation and psychological symptoms in adolescent girls with anorexia. First, the psychometric properties of the Adolescent Dissociative Experiences Scale (A-DES) were examined using data from 181 nonclinical adolescent boys and girls. Thereafter, A-DES scores and correlations with a range of psychological symptoms were compared across 20 girls with anorexia, 19 mixed clinical girls, and 86 nonclinical girls. The A-DES had a one-factor structure and good psychometric characteristics. Dissociation scores were significantly correlated with level of symptomatology for all groups. Although the group with anorexia did not have significantly higher dissociation scores than the other two groups, dissociation in the anorexic girls was related to psychopathology in a distinct way. Adolescent girls with anorexia appear to use dissociation specifically to avoid processing angry affect with an interpersonal basis, although it is also related to their use of somatization, and obsessive-compulsive features.

Pattern of birth in adults with anorexia nervosa.

While women with anorexia nervosa are more likely to be born in March through June (in the northern hemisphere), there is no coherent model that explains this association. This study examined the birth pattern of adult restrictive and binge-purge anorexics and whether environmental temperature at assumed conception is a relevant factor. Retrospective analysis of the case notes of 195 adult anorexics was used to determine diagnosis, date of birth, eating attitudes, and body mass index. Meteorological records were used to determine temperature at assumed point of conception. Restrictive anorexics were significantly more likely than binge-purge anorexics to be born in April through June (, conceived July through September). A higher environmental temperature at the point of assumed conception was more likely to be found in restrictive anorexics than in anorexics of the binge-purge subtype. A higher environmental temperature at the assumed point of conception was associated with more restrictive eating attitudes during adulthood, but only among the restrictive anorexics. Possible explanations and implications of these findings are discussed.
