The present study examines the reliability and validity of the Turkish version of the Lifespan Sibling Relationship Scale (LSRS; Riggio, 2000). A total of 578 (336 female, 242 male) Turkish emerging adults participated in this study. A Confirmatory Factor Analysis (CFA) was used to test construct validity for the original six-factor model of the scale with 48 items. Results of the CFA indicated a good model fit. Furthermore, the second-order CFA result showed that the scale can be scored for both the subdimensions and the test as a whole. Multi-group CFA result revealed that the measured construct is invariant across the genders. The results suggested that the Turkish version of the LSRS had adequate internal consistency and construct validity, indicating that it can be reliably used to measure attitudes toward sibling relationship in emerging adulthood among a Turkish population.

土耳其新兴成人样本寿命兄弟姐妹关系量表的信度和效度

本研究检验了土耳其语版兄弟姐妹关系量表 (LSRS; Riggio, 2000) 的信度和效度。共有 578 名（336 名女性，242 名男性）土耳其新兴成年人参与了这项研究。使用验证性因素分析 (CFA) 来测试具有 48 个项目的原始六因素量表模型的结构效度。CFA 的结果表明模型拟合良好。此外，二阶 CFA 结果表明，该量表可以针对子维度和整个测试进行评分。多组 CFA 结果显示，测量的结构在性别之间是不变的。结果表明，土耳其语版的 LSRS 具有足够的内部一致性和结构效度，
