BACKGROUND
Up to fifty percent of alcohol dependent individuals have alexithymia, a personality trait characterised by difficulties identifying and describing feelings, a lack of imagination and an externalised cognitive style. Although studies have examined alexithymia in relation to alcohol dependence, no research exists on mechanisms underlying this relationship. The present study examined the mediational effect of alcohol expectancies on alexithymia and alcohol dependence.
METHODS
230 outpatients completed the Toronto Alexithymia Scale (TAS-20), the Drinking Expectancy Questionnaire (DEQ) and the Alcohol Use Disorder Identification Test (AUDIT).
RESULTS
Regression analysis showed that alexithymia and alcohol dependence was, in two of three cases, partially mediated through alcohol expectancy.
CONCLUSIONS
Alcohol expectancies of assertion and affective change show promise as mediators of alcohol dependence in individuals with alexithymia.
背景
多达百分之五十的酒精依赖个体存在述情障碍，这是一种以难以识别和描述情感、缺乏想象力和外化认知风格为特征的人格特质。尽管已有研究探讨了述情障碍与酒精依赖之间的关系，但对于这种关系的潜在机制仍未有研究。本研究旨在检验酒精预期对述情障碍和酒精依赖的中介作用。
方法
230 名门诊患者完成了多伦多述情障碍量表（TAS-20）、饮酒预期问卷（DEQ）和酒精使用障碍识别测试（AUDIT）。
结果
回归分析显示，在三种情况中的两种情况下，酒精预期部分中介了述情障碍和酒精依赖之间的关系。
结论
在存在述情障碍的个体中，表达和情感改变的酒精预期显示出作为酒精依赖的中介的潜力。
