Psychotic symptoms have been reported at varying rates in the general population in the West. We studied the association of psychotic symptoms with educational attainment and other psychiatric disorders in 23,248 male pre-enlistees for National Service in Singapore.
In a 2-stage assessment, these enlistees were first screened with the Self-Reporting Questionnaire (SRQ-24) and the CRAFFT. Those screened positive were then assessed by the Composite International Diagnostic Interview (CIDI) to establish the presence of psychiatric disorders based on the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV).
The rate of psychotic symptoms (after excluding those with psychotic disorders) was 8.2% (n = 1,909). A multinomial logistic regression using the controls as the reference group revealed that younger age, lower PSLE scores, and mood and anxiety disorder remained significantly associated with both the diagnoses of psychotic disorders and the presence of psychotic symptoms.
A combination of categorical and dimensional representation of psychopathology for the diagnosis of psychotic disorders would better inform treatment and prognosis as there is a considerable overlap in the presentation of psychotic symptoms and psychotic disorders.
在西方，一般人群中报告了不同比例的精神病症状。我们研究了精神病症状与教育程度和新加坡 23248 名男性义务兵役前应征者中其他精神障碍的关系。
在 2 阶段评估中，这些应征者首先使用自我报告问卷 (SRQ-24) 和 CRAFFT 进行筛查。那些筛查呈阳性的人随后通过复合国际诊断访谈 (CIDI) 进行评估，根据精神障碍诊断与统计手册，第 4 版 (DSM-IV) 确定精神障碍的存在。
精神病症状的发生率（排除精神病障碍后）为 8.2%（n=1909）。使用对照组作为参考组的多项逻辑回归显示，年龄较小、PSLE 分数较低以及情绪和焦虑障碍与精神病障碍的诊断和精神病症状的存在仍然存在显著相关性。
对精神病障碍进行分类和维度表现的组合诊断将更好地告知治疗和预后，因为精神病症状和精神病障碍的表现有相当大的重叠。
