This paper describes the prevalence and incidence of psychiatric disorders in IBS patients using a standardized psychiatric interview, and proposes a psychological model for investigating one aspect of IBS. Forty-four IBS patients and 28 nonclinical participants received a psychiatric interview (Diagnostic Interview Schedule) and completed the Lie Scale of the Eysenck Personality Inventory (L-EPI). Results indicated that a significant percentage (59%) of the IBS group met DSM-III criteria for a psychiatric disorder within the last year, far more than occurred in the matched nonclinical comparison group. Relative to the comparison group, the IBS group also had significantly higher lie scores on the EPI indicating a response style of social desirability. On the basis of these findings, together with earlier work by Latimer's group, a conceptual model was formulated on the notion that some IBS patients may have a self-schema (i.e. knowledge of self, stored in memory) characterized by social desirability. We suggest that the construct of self-schema may be helpful in differentiating IBS from psychiatric groups both conceptually and therapeutically.
本文采用标准化的精神科访谈描述了肠易激综合征（IBS）患者精神障碍的患病率和发病率，并提出了一个用于研究IBS某一方面的心理学模型。44名IBS患者和28名非临床参与者接受了精神科访谈（诊断性访谈表），并完成了艾森克人格问卷的说谎量表（L-EPI）。结果表明，IBS组中有相当比例（59%）的患者在过去一年中符合精神障碍的DSM-III标准，远远高于匹配的非临床对照组。相对于对照组，IBS组在EPI上的说谎得分也显著更高，表明其具有社会期望的反应方式。基于这些发现，结合拉蒂默团队早期的研究工作，形成了一个概念模型，其观点是一些IBS患者可能具有以社会期望为特征的自我图式（即存储在记忆中的自我认知）。我们认为，自我图式这一概念在概念和治疗方面可能有助于区分IBS与精神疾病群体。
