Developed based on the Clinical Assessment Interview for Negative Symptoms (CAINS), the Motivation and Pleasure Scale-Self Report (MAP-SR) was designed to address the conceptual and psychometric limitations of other instruments assessing negative symptoms. We sought to validate and extend the applicability of the MAP-SR in the Chinese context across the schizophrenia spectrum.
Three samples, including college students, individuals with social anhedonia and patients with schizophrenia, were recruited. Test-retest reliability, internal consistency, factor structure, and convergent/discriminant validity of the MAP-SR were examined. The group differences between the three participant groups were examined.
A four-factor structure of the MAP-SR was found consistently in all three groups of participants. The scale showed convergent/discriminant validity in patients with schizophrenia and individuals with social anhedonia, along with good reliability found in schizophrenia patients. The MAP-SR was also able to distinguish individuals with SocAnh and patients with SZ from matched controls.
The MAP-SR is a valid and reliable instrument in assessing negative symptoms in individuals along the schizophrenia spectrum.
基于临床负面症状评估访谈（CAINS）开发的动机和愉悦量表-自我报告（MAP-SR）旨在解决其他评估负面症状的工具在概念和心理计量学方面的局限性。我们试图在中国范围内的精神分裂症谱系中验证和扩展 MAP-SR 的适用性。
共招募了三个样本，包括大学生、社会快感缺乏个体和精神分裂症患者。考察了 MAP-SR 的重测信度、内部一致性、因子结构和聚合/区分效度。并检验了三组参与者之间的群体差异。
在所有三组参与者中，MAP-SR 均呈现出一个四因子结构。该量表在精神分裂症患者和社会快感缺乏个体中表现出聚合/区分效度，同时在精神分裂症患者中具有良好的信度。MAP-SR 还能够区分社会快感缺乏个体和精神分裂症患者与匹配对照组。
MAP-SR 是一种在精神分裂症谱系人群中评估负面症状的有效且可靠的工具。
