This study aimed to compare the psychological symptoms of humidifier disinfectant survivors to the general population and explore socio-demographic factors influencing survivors' psychological symptoms. A one-way Multivariate Analysis of Covariance (MANCOVA) and a series of two-way MANCOVA were conducted with a sample of 228 humidifier disinfectant survivors and 228 controls. The results demonstrated that the survivor group displayed higher anxious/depressed symptoms, withdrawn symptoms, somatic complaints, thought problems, attention problems, aggressive behavior and rule-breaking behavior than the general group. Moreover, among the socio-demographic factors, the two-way interaction effects of group × family economic status and group × number of friends were found to be statistically significant. The limitations and implications of this study are discussed.
本研究旨在比较加湿器杀菌剂幸存者与一般人群的心理症状，并探讨影响幸存者心理症状的社会人口学因素。采用 228 名加湿器杀菌剂幸存者和 228 名对照的单因素协方差分析（MANCOVA）和一系列双向 MANCOVA 进行分析。结果表明，幸存者组表现出更高的焦虑/抑郁症状、退缩症状、躯体抱怨、思维问题、注意力问题、攻击行为和违反规则行为，比一般组更明显。此外，在社会人口学因素中，发现组×家庭经济状况和组×朋友数量的双向交互作用具有统计学意义。讨论了本研究的局限性和意义。
