The major purpose of this study was to examine alexithymia in relationship to depression and Axis II psychopathology in eating disorder patients.
Fifty-three female inpatients representing three DSM-IV eating disorder diagnostic groups and 14 control subjects completed the Toronto Alexithymia Scale (TAS), the Eating Disorder Inventory-2, and the Beck Depression Inventory within the first week of their hospital admission and shortly before discharge. Structured Clinical Interviews for DSM-III-R (SCID) I and II were also conducted. Multiple regression analyses were used to determine the contribution of mood, diagnostic, and personality variables in predicting the alexithymia score.
After controlling for depression, only the TAS factor, "difficulty expressing feelings," remained significantly different between groups, with the anorexia nervosa-restrictors (AN-R) having significantly higher scores than controls and bulimia nervosa patients. This factor appears to be a relatively stable personality characteristic in AN-R. The level of depression and the presence of avoidant personality disorder were the most predictable variables for the alexithymia total score.
本研究的主要目的是探讨进食障碍患者的述情障碍与抑郁及轴II精神病理学之间的关系。
53名代表三种DSM-IV进食障碍诊断组的女性住院患者和14名对照受试者在入院第一周内及出院前不久完成了多伦多述情障碍量表（TAS）、进食障碍问卷-2和贝克抑郁量表。还进行了DSM-III-R（SCID）I和II的结构化临床访谈。多元回归分析用于确定情绪、诊断和人格变量在预测述情障碍得分中的作用。
在控制抑郁因素后，仅TAS因子“表达情感困难”在各组之间仍存在显著差异，神经性厌食症限制型（AN-R）患者的得分显著高于对照组和神经性贪食症患者。该因子似乎是AN-R中相对稳定的人格特征。抑郁水平和回避型人格障碍的存在是述情障碍总分最可预测的变量。
