Nonclinical psychotic symptoms (for example, low intensity or low frequency psychotic symptoms such as ideas of reference or single word auditory hallucinations) are common in adolescents and may be associated with an increased risk of developing a psychotic disorder in adulthood. Those at high risk of developing a psychotic disorder appear to perform poorly on facial emotion recognition tasks but the relationship between facial emotion recognition and nonclinical "psychosis like symptoms" (PLIKS) in children is unclear. We aimed to examine the association between childhood facial emotion recognition and PLIKS in adolescents.
Longitudinal study using a large birth cohort. 6455 subjects completed a semistructured clinical assessment for psychotic symptoms (the PLIKSi) at the mean age of 12.9 (SD=0.23). Facial emotion recognition (using the DANVA) was previously assessed at the age of 8 in the cohort.
There was no increase in odds of reporting any PLIKS either in relation to the total score on the measure of facial emotion recognition or for the individual emotion scores of fear, sadness, anger, and happiness. Similar results were also found when examining more intense and/or more frequently experienced psychotic symptoms.
Deficits in facial emotion recognition in 8-year-olds do not appear to predict later reporting of nonclinical psychotic symptoms in early adolescence. The results do not support the proposal that recognition of emotion is a trait phenomenon in those individuals at increased risk for psychosis. However, further research is warranted in older children/adolescents when more subtle emotion recognition deficits can be investigated.
非临床性精神病症状（例如，低强度或低频的精神病症状，如意向性幻觉或单词性幻听）在青少年中很常见，并且可能与成年后患精神病性障碍的风险增加有关。那些有患精神病性障碍高风险的人在面部情绪识别任务上表现似乎较差，但儿童面部情绪识别与非临床“类精神病症状”（PLIKS）之间的关系尚不清楚。我们旨在研究儿童面部情绪识别与青少年PLIKS之间的关联。
使用一个大型出生队列进行纵向研究。6455名受试者在平均年龄12.9岁（标准差=0.23）时完成了一项针对精神病症状的半结构化临床评估（PLIKSi）。该队列中先前在8岁时评估了面部情绪识别（使用DANVA）。
无论是与面部情绪识别测量的总分相比，还是与恐惧、悲伤、愤怒和快乐等个体情绪得分相比，报告任何PLIKS的几率都没有增加。在检查更强烈和/或更频繁出现的精神病症状时也发现了类似结果。
8岁儿童面部情绪识别缺陷似乎不能预测青春期早期非临床精神病症状的后期报告。这些结果不支持情绪识别是精神病风险增加个体的一种特质现象这一观点。然而，当可以研究更细微的情绪识别缺陷时，对年龄较大的儿童/青少年进行进一步研究是有必要的。
