Evidence suggests that emotional awareness-the ability to identify and label emotions-may be impaired in schizophrenia and related to positive symptom severity. Exposure to childhood maltreatment is a risk factor for both low emotional awareness and positive symptoms.
The current investigation examines associations between a performance-based measure of emotional awareness, positive symptom severity, and childhood maltreatment exposure in 44 individuals with a schizophrenia-spectrum disorder and 48 healthy comparison participants using the electronic Levels of Emotional Awareness Scale (eLEAS), Positive and Negative Syndrome Scale (PANSS) and Childhood Trauma Questionnaire (CTQ).
Patients demonstrated significant deficits in emotional awareness overall, which was true for both self and others. In patients, lower emotional awareness was significantly associated with more severe positive symptoms. Emotional awareness was significantly impaired in patients with schizophrenia with self-reported maltreatment exposure, relative to other groups. Severity of maltreatment was not significantly associated with emotional awareness or positive symptoms when looking continuously, and there was no significant indirect effect.
These data suggest that emotional awareness impairments observed in schizophrenia may be exacerbated by exposure to childhood maltreatment, possibly putting individuals at greater risk for experiencing positive symptoms of psychosis.
有证据表明，情绪意识（即识别和标记情绪的能力）在精神分裂症中可能受损，且与阳性症状的严重程度有关。童年期受虐待是情绪意识低下和阳性症状的一个风险因素。
本研究使用电子情绪意识水平量表（eLEAS）、阳性和阴性症状量表（PANSS）以及儿童创伤问卷（CTQ），对44名精神分裂症谱系障碍患者和48名健康对照参与者进行了基于表现的情绪意识测量、阳性症状严重程度与童年期受虐待经历之间的关联研究。
患者总体上在情绪意识方面存在显著缺陷，自我和他人的情绪意识均如此。在患者中，较低的情绪意识与更严重的阳性症状显著相关。与其他组相比，自我报告有受虐待经历的精神分裂症患者的情绪意识明显受损。持续观察时，虐待的严重程度与情绪意识或阳性症状无显著关联，且不存在显著的间接效应。
这些数据表明，童年期受虐待可能会加剧精神分裂症患者中观察到的情绪意识损害，这可能会使个体出现精神病阳性症状的风险更高。
