The transition from financial dependence on one’s parents to financial self-sufficiency is one of the most relevant transitions during emerging adulthood. It is important to have an instrument able to assess emerging adults’ financial capabilities and to detect its change over time. The current article aims to collect international evidence of the Financial Identity Scale (FIS) validity and reliability. Cross-sectional data collected from 2,501 emerging adults aged 18–25 and belonging to three different countries—U.S. (n = 1,535), Italy (n = 485), and Lithuania (n = 481)—were adopted to test score structure validity, generalizability, sensitivity to difference, criterion-related validity, and internal consistency. Instead, four-wave longitudinal data, available for the American sample only (n = 1,900), were adopted to test FIS structural stability and sensitivity to change. As recommended by the contemporary view of validity, different structural equation models were performed. Findings suggest that FIS scores are valid and reliable. The implications for researchers and practitioners are discussed.

金融身份量表（FIS）：新兴成年人中的跨国验证和度量不变性研究

从对父母的经济依赖到经济自给自足的过渡是成年后最重要的过渡之一。重要的是要拥有一种能够评估新兴成年人的财务能力并检测其随时间变化的工具。当前的文章旨在收集金融身份量表（FIS）有效性和可靠性的国际证据。我们采用了来自2501个年龄在18-25岁的新兴成年人的横截面数据，这些成年人分别属于三个国家（美国（n = 1535），意大利（n = 485）和立陶宛（n = 481）），以测试评分结构的有效性，概化性，对差异的敏感性，与标准相关的有效性和内部一致性。取而代之的是仅适用于美国样本的四波纵向数据（n = 1,900），通过测试FIS的结构稳定性和变化敏感性。根据当代有效性观点的建议，执行了不同的结构方程模型。调查结果表明，FIS分数有效且可靠。讨论了对研究人员和从业人员的意义。
