述情障碍青少年心理理论能力的研究

Theory of mind impairment in youngsters affected by alexithymia

目的通过对青少年述情障碍者心理理论能力的研究，从冷、热心理理论和一、二级推理能力不同角度揭示述情障碍者心理理论能力损害的状况。方法使用Yoni测验中文版和一系列背景测验，比较31名述情障碍者和30名正常对照被试的心理理论能力。结果述情障碍组热心理理论正确得分[（35．81±6．30）分]与正常对照组的正确得分[（39．83±6．02）分]比较，差异有统计学意义（t=-2．55，P〈0．05）。主要表现在二级热心理理论的正确得分[（24．55±6．01）分]明显低于正常对照组[（28．30±6．04）分]，差异有统计学意义（t=-2．76，P〈0．01）。而述情障碍组冷心理理论的正确得分[（19．00±2．11）分]与正常对照组[（19．43±2．13）分]比较，差异无统计学意义（t=-0．80，P〉0．05）。结论述情障碍者热心理理论能力存在着缺陷，缺陷主要体现在二级推理能力。

Objective To study theolT of mind（TOM） of youngsters in alexithymia, and to assess the impairment in TOM by analysing affective and cognitive TOM and the first and second order judgment. Methods TOM of 31 alexithymics and 30 healthy control subjects get be examined by the Chinese version of ＂Yoni task＂ and series of tests. Results There were significant differences in affective TOM accuracy scores between alexithymics and healthy controls （ （ 35.81 ± 6.30） vs （39.83 ± 6.02）, t = - 2.55, P 〈 0.05 ）. Particularly, alexithymics got significantly lower accuracy scores in the second order judgement of affective TOM （ （24.35 ± 6.01 ） vs （ 28.80 ±6.04 ） , t = - 2.76, P 〈 0.01 ）. However, there were no in cognitive TOM accuracy score..s be- tween alexithymics and health controls （ （ 19.00 ±2.11 ） vs （ 19.43 ± 2. 13 ）, t = - 0.80, P 〉 0.05 ）. Conclu- sion Alexithymics are impaired in affective TOM, specially the second order judgement.
