中学生述情障碍及其影响因素的潜在转变

Latent transition analysis of alexithymia and its influencing factors in middle school students

目的:运用追踪研究设计和潜在转变分析法研究中学生述情障碍潜在类别的转变特点及其影响因素。方法:以湖南省7所中学的1447名中学生为被试进行为期6个月的追踪,对数据进行潜在转变分析。结果:①中学生述情障碍可分为高述情障碍组、普通组和低述情障碍组3个类别;②高述情障碍组稳定性最弱,保持原潜在状态的概率为37.7%,普通组和低述情障碍组保持原潜在状态的概率分别是58.1%和50.7%;③高述情障碍组倾向于向普通组转变,转变概率为50.2%;④社交焦虑和性别在述情障碍类别转变中起显著作用。结论:中学生述情障碍存在高述情障碍组、普通组和低述情障碍组3个潜在类别;述情障碍转变呈现出“缓解模式”,高述情障碍组会转变到普通组和低述情障碍组;且转变方向受性别和社交焦虑影响。

Objective:To study the transition characteristics and influencing factors of the latent class of alexithymia in middle school students by longitudinal design and latent transition analysis.Methods:A follow-up study was conducted on 1447 middle school students from 7 middle schools in Hunan Province at an interval of 6 months to analyze the latent transition change.Results:①Alexithymia in middle school students could be divided into three categories:High alexithymia class,common class and low alexithymia class.②The stability of the high alexithymia class was the weakest,and the probability of maintaining the original latent state was 37.7%.The probability of maintaining the original latent state was 58.1%and 50.7%in the common class and the low alexithymia class,respectively.③The high alexithymia class tended to transition to the common class,and the probability of transition was 50.2%.④Social anxiety and gender played a significant role in the change of alexithymia.Conclusion:Middle school students have three latent classes of alexithymia:High alexithymia class,ordinary class,and low alexithymia class;The transition of alexithymia presents a"relief mode",with the high alexithymia class transitioning to the ordinary class and the low alexithymia class;And the direction of transition is influenced by gender and social anxiety.
