The sibling relationship and its potential impact on neurodevelopment and mental health are important areas of neuroscientific research. Validation of the tools assessing the quality of the sibling relationship would be the first essential step for conducting neurobiological and psychosocial studies related to the sibling relationship. However, to the best of our knowledge, no sibling relationship assessment tools have been empirically validated in Korean. We aimed to evaluate the psychometric properties of the Korean version of the Lifespan Sibling Relationship Scale (LSRS), which is one of the most commonly used self-report questionnaires to assess the quality of the sibling relationship. A total of 109 adults completed a series of self-report questionnaires including the LSRS, the mental health subscale of the Medical Outcomes Study-Short Form 36 version 2 (SF36v2), the Satisfaction with Life Scale (SLS), and the Marlowe-Crowne Social Desirability Scale (MC-SDS). The internal consistency, subscale intercorrelations, one-week test-retest reliability, convergent validity, divergent validity, and the construct validity were assessed. All six subscale scores and the total score of the LSRS demonstrated good internal consistency (Cronbach's α=0.85-0.94) and good test-retest reliability (intraclass correlation coefficient=0.77-0.92). Correlations of the LSRS with the SF36v2 mental health score (r=0.32, p=0.01) and with the SLS (r=0.27, p=0.04) supported the good convergent validity. The divergent validity was shown by the non-significant correlation of the LSRS with the MC-SDS (r=0.15, p=0.26). Two factors were extracted through factor analysis, which explained 78.63% of the total variance. The three Adult subscales loaded on the first factor and the three Child subscales loaded on the second factor. Results suggest that the Korean version of the LSRS is a reliable and valid tool for examining the sibling relationship.
同胞关系及其对神经发育和心理健康的潜在影响是神经科学研究的重要领域。验证评估同胞关系质量的工具将是进行与同胞关系相关的神经生物学和社会心理学研究的第一步。然而，据我们所知，在韩国，还没有经过实证验证的同胞关系评估工具。我们旨在评估生命周期同胞关系量表 (LSRS) 的韩语版本的心理测量特性，LSRS 是评估同胞关系质量最常用的自我报告问卷之一。共有 109 名成年人完成了一系列自我报告问卷，包括 LSRS、医疗结局研究-短表单 36 版本 2（SF36v2）心理健康子量表、生活满意度量表（SLS）和 Marlowe-Crowne 社会期望量表（MC-SDS）。评估了内部一致性、分量表相关性、一周重测信度、聚合效度、发散效度和结构效度。LSRS 的所有六个分量表得分和总分均表现出良好的内部一致性（Cronbach's α=0.85-0.94）和良好的重测信度（组内相关系数=0.77-0.92）。LSRS 与 SF36v2 心理健康评分（r=0.32，p=0.01）和 SLS（r=0.27，p=0.04）的相关性支持了良好的聚合效度。LSRS 与 MC-SDS 的非显著相关性（r=0.15，p=0.26）表明了发散效度。通过因子分析提取了两个因子，解释了总方差的 78.63%。三个成人分量表加载在第一个因子上，三个儿童分量表加载在第二个因子上。结果表明，LSRS 的韩语版本是评估同胞关系的可靠有效工具。
