BACKGROUND Compassionate love is defined as awareness and understanding of one's suffering, connecting with the distress, and being emotionally and cognitively moved to alleviate suffering. The Compassionate Love Scale for Humanity (CLS-H) was developed to measure compassion towards strangers who need help and/or are vulnerable. The present study aimed to develop an abbreviated version of the CLS-H using item response theory to provide a precise and non-redundant compassion measure for use in research and practice. METHODS Undergraduate students (N = 790; 65.8% females) completed the CLS-H and other measures intended to establish external validity. Items for the short version were selected based on high amounts of information and taking into account the content coverage of the construct. RESULTS The shortened scale consisted of 9 items and performed well in measuring a large spectrum of the underlying construct with acceptable reliability. In terms of validity, the previously observed pattern of correlations was confirmed demonstrating positive associations between compassionate love and measures of self-esteem, positive affect, and life satisfaction, as well as negative associations with negative affect and anxiety. CONCLUSIONS Using IRT, we obtained a brief, precise, and valid tool for assessing compassionate love.

修改后的人类爱心爱心量表（CLS-H-SF）的简短版本：项目反应理论分析和有效性测试的证据。

背景技术富有同情心的爱被定义为对一个人的痛苦的认识和理解，与苦难联系在一起，并在情感和认知上为减轻痛苦而运动。仁慈的人类爱心量表（CLS-H）旨在衡量对需要帮助和/或脆弱的陌生人的同情心。本研究旨在使用项目反应理论开发CLS-H的缩写版本，以提供一种精确且非冗余的同情措施，用于研究和实践。方法本科生（N = 790；女性65.8％）完成了CLS-H和其他旨在建立外部效度的措施。根据大量信息并考虑到构造的内容覆盖范围来选择简短版本的项目。结果缩短后的规模包括9个项目，并且在测量范围广泛的基础结构中表现良好，并且具有可接受的可靠性。在有效性方面，证实了先前观察到的相关模式，表明了同情心的爱与自尊，积极影响和生活满意度之间的正相关，以及消极影响和焦虑的负相关。结论使用IRT，我们获得了一个简短，准确而有效的工具来评估富有同情心的爱。以及带有负面影响和焦虑的负面联想。结论使用IRT，我们获得了一个简短，准确而有效的工具来评估富有同情心的爱。以及带有负面影响和焦虑的负面联想。结论使用IRT，我们获得了一个简短，准确而有效的工具来评估富有同情心的爱。
