虽然精神分裂症的阴性症状与一系列有害后果有关(例如，White等人，2009年)，但并不是所有的精神分裂症患者都会出现阴性症状(例如，Blanchard等人，2005年)。因此，快速筛选和识别患者以进行更密集的临床访谈评估的方法可能具有重要的临床和研究实用价值。本研究是对新开发的阴性症状临床评估访谈自我报告版本的信度和效度的初步检验(Cains；Blanchard等人，2011年；福布斯等人，2010年；Horan等人，2011年)。CAINS-SR是一种30个条目的自我报告测量工具，用于评估阴性症状的经验性(情绪失调症、快感缺失、无社交)和表现性(钝化情感、冷漠)领域。参与者(N=69)完成了CAINS-SR问卷，并接受了使用CAINS的症状访谈和其他评估精神病、情感和其他症状的非阴性症状访谈。CAINS-SR的经验分量表表现出良好的内部一致性、收敛效度和区分效度，而表达分量表的心理测量学特性较差，表明消极症状的自我报告应侧重于经验领域。总体而言，初步研究结果表明，CAINS-SR(解决经验缺陷)可能是对临床医生评定的面谈措施的有益补充。未来对CAINS-SR的敏感性和特异性的研究将确定其作为筛查指标的适用性。
Though negative symptoms in schizophrenia are associated with a host of deleterious outcomes (e.g., White et al., 2009), not all individuals with schizophrenia suffer from negative symptoms (e.g., Blanchard et al., 2005). Thus, methods to quickly screen and identify patients for more intensive clinical interview assessments may have significant clinical and research utility. The present study is a preliminary examination of the reliability and validity of a self-report version of the newly developed Clinical Assessment Interview for Negative Symptoms (CAINS; Blanchard et al., 2011; Forbes et al., 2010; Horan et al., 2011). The CAINS-SR is a 30-item self-report measure that assesses Experiential (avolition, anhedonia, asociality) and Expressive (blunted affect, alogia) domains of negative symptoms. Participants (N=69) completed the CAINS-SR questionnaire and were evaluated with symptom interviews using the CAINS and other non-negative symptom interviews that assessed psychotic, affective, and other symptoms. The Experience subscale of the CAINS-SR demonstrated good internal consistency, convergent validity, and discriminant validity, while the poorer psychometric properties of the Expression subscale suggest that self-report of negative symptoms should focus on the experiential domain. Overall, preliminary findings indicate that the CAINS-SR (addressing experiential deficits) may be a useful complement to the clinician-rated interview measure. Future research on the sensitivity and specificity of the CAINS-SR will determine its suitability as a screening measure.
