The clinical validity of the newly developed 20-item Toronto Alexithymia Scale (TAS-20) with regard to the concept of somatization remains to be further established. This study attempts to determine the relationship between alexithymia and measures of psychopathology and illness severity in patients with somatoform disorders as compared to patients with chronic medical illness.
Forty inpatients with a DSM-III-R somatoform disorder and 29 inpatients with a chronic medical illness completed the German version of the TAS-20, SCL-90-R, Whiteley Index, and a global rating of the severity of current psychosocial impairment.
Patients with a somatoform disorder scored significantly higher on the TAS-20 than the medically ill. As a result of stepwise multiple regression analysis, the SCL-90-R somatization scale emerged as a significant predictor of alexithymia in the somatizing patients, while the SCL-90-R depression scale and the severity of psychosocial impairment significantly predicted alexithymia in the medically ill.
The results underline the clinical validity of the TAS-20 (German version) as well as the alexithymia construct.
新开发的20项多伦多述情障碍量表(TAS - 20)在躯体化概念方面的临床有效性仍有待进一步确定。本研究旨在确定与慢性内科疾病患者相比,躯体形式障碍患者的述情障碍与精神病理学指标及疾病严重程度之间的关系。
40例符合DSM - III - R躯体形式障碍的住院患者和29例患有慢性内科疾病的住院患者完成了德文版的TAS - 20、症状自评量表(SCL - 90 - R)、怀特利指数以及当前心理社会功能损害严重程度的整体评定。
躯体形式障碍患者在TAS - 20上的得分显著高于内科疾病患者。经过逐步多元回归分析,SCL - 90 - R躯体化量表成为躯体化患者述情障碍的显著预测指标,而SCL - 90 - R抑郁量表和心理社会功能损害严重程度则显著预测了内科疾病患者的述情障碍。
研究结果强调了TAS - 20(德文版)以及述情障碍概念的临床有效性。
