The purpose of the study was to better understand the phenomenology of bulimic symptomatology in an adolescent clinic sample.
Adolescents with bulimia nervosa (BN; n = 36) and eating disorders not otherwise specified-purging but no objective bulimic episodes (EDNOS-P; n = 20) were compared on the Eating Disorder Examination (EDE), the Beck Depression Inventory (BDI), the Rosenberg Self-Esteem Scale (RSES), and the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS).
Subjects with EDNOS-P and BN were equivalent in terms of age and weight, but were less likely to have intact families. Nearly one half of EDNOS-P subjects purged exclusively outside of eating episodes in which they experienced a sense of loss of control. Although still at clinically significant levels, EDNOS-P subjects reported less concerns regarding weight, shape, and eating relative to BN. Groups were not significantly different on psychiatric comorbidity, but differed on self-esteem.
Results prompt reappraisal of current criteria of BN to encompass those who purge without binge eating.
本研究旨在更深入地了解青少年临床样本中贪食症症状的现象学。
对神经性贪食症(BN;n = 36)青少年和未另行指定的饮食失调症——有清除行为但无客观贪食发作(EDNOS-P;n = 20)的青少年进行比较,比较内容包括饮食失调检查(EDE)、贝克抑郁量表(BDI)、罗森伯格自尊量表(RSES)以及学龄儿童情感障碍和精神分裂症量表(K-SADS)。
EDNOS-P组和BN组在年龄和体重方面相当,但拥有完整家庭的可能性较小。近一半的EDNOS-P组受试者仅在未经历失控感的进食发作之外进行清除行为。尽管仍处于临床显著水平,但与BN组相比,EDNOS-P组受试者对体重、体型和饮食的担忧较少。两组在精神共病方面无显著差异,但在自尊方面存在差异。
研究结果促使重新评估当前BN的标准,以涵盖那些有清除行为但无暴饮暴食的人。
