Measurement tools that can assess personality traits rendering people more susceptible to engagement with and compliance in scams can help identify at-risk populations. The brief, 30-item version of the Susceptibility to Persuasion-II (StP-II-B) scale is a recently developed instrument for assessing 10 personality traits that play a role in scam compliance; however, psychometric evidence supporting the use of this scale is limited. This study aimed to validate the StP-II-B by examining its internal consistency reliability, factor structure, as well as age- and gender-related measurement invariance with a sample of 1287 Canadians aged 16 years and older. Confirmatory factor analysis supported a 10-factor structure identified in previous research. Good internal consistency reliability was obtained for each of the 10 subscales. This 10-factor structure was found to be invariant across age and gender at configural, metric, and scalar levels, suggesting that the StP-II-B was conceptualized in the same way across age and gender and that meaningful comparisons of factor scores could be made. Age and gender differences were found in most factors, with younger individuals and men scoring higher than older individuals and women. This study supports the use of the StP-II-B as a valid and reliable scale for measuring personality traits associated with scam compliance in the Canadian general population and offers insights into age and gender cohorts that may be at higher risk of scam victimization.
能够评估使人更容易参与诈骗并遵守诈骗行为的人格特质的测量工具，有助于识别高危人群。简短的、包含30个条目的说服易感性-II（StP-II-B）量表是最近开发的一种用于评估在诈骗依从性中起作用的10种人格特质的工具；然而，支持使用该量表的心理测量学证据有限。本研究旨在通过对1287名16岁及以上的加拿大人进行样本分析，检验其内部一致性信度、因子结构以及与年龄和性别相关的测量不变性，从而验证StP-II-B量表。验证性因素分析支持了先前研究中确定的10因素结构。10个分量表均获得了良好的内部一致性信度。结果发现，这10因素结构在构型、度量和标量水平上在年龄和性别上是不变的，这表明StP-II-B量表在年龄和性别上的概念化方式相同，并且可以对因子得分进行有意义的比较。在大多数因素中发现了年龄和性别差异，年轻人和男性的得分高于老年人和女性。本研究支持将StP-II-B量表作为一种有效且可靠的量表，用于测量加拿大普通人群中与诈骗依从性相关的人格特质，并为可能面临更高诈骗受害风险的年龄和性别群体提供了见解。
