青少年述情障碍特征的潜在类别分析

Features of Alexithymia in Adolescents: A Latent Class Analysis

目的:对青少年述情障碍的潜在风险特征进行探索性潜在类别分析。方法:采用多伦多述情障碍20个条目量表(TAS-20)、流调中心用抑郁量表(CES-D)和症状自评量表-躯体化分量表(SCL-90-Somatization)对湖南省长沙市4所中学的2017名青少年进行问卷调查。结果:对青少年述情障碍特征进行潜在类别分析,统计指标支持了3个潜类别的模型,分别定义为:"述情障碍组"(18%)、"情感表达不良组"(35%)和"情感表达良好组"(47%)。进一步的分析发现:相较情感表达良好组而言,女生与低龄青少年在述情障碍组和情感表达不良组所占比例更大。述情障碍组的抑郁症状与躯体化水平均显著高于情感表达良好组和情感表达不良组(P<0.001)。结论:青少年述情障碍存在三种不同潜在类别;女生和低龄青少年的述情障碍问题更为突出;述情障碍青少年有着更多的抑郁和躯体化症状。

Objective： To explore the feature of alexithymia in adolescents using latent class analysis. Methods： 2017 adolescents from 4 middle schools in Changsha, Hunan province completed 20- item Toronto Alexithymia Scale（TAS-20）, Epidemiological Studies Depression Scale（CES- D） and SCL- 90- Somatization. Results： The results indicated that there were three latent classes of alexithymia among adolescents, namely alexithymia group（AG,18%）, difficultly emotional expression group（DEEG,35%） and well emotional expression group group（WEEG, 47%）. Further analysis found that alexithymia was associated with female gender, lower age, depression and somatization. Conclusion： There were three latent classes of alexithymia among these adolescents. The ratio of alexithymia of female and low-aged adolescents was higher than that of male and high-aged adolescents. Alexithymia adolescents showed more depressive and somatic symptoms.
