Multiple studies have shown that the Massachusetts Youth Screening Instrument-2nd Version (MAYSI-2) has strong validity and reliability. Justice involved youth are often administered the MAYSI-2 on repeated occasions. The purpose of the current study was to test the equivalence of measurement properties over time for males who were administered the MAYSI-2 on multiple occasions. Archived data were drawn from the Utah Juvenile Justice Services administration, which consisted of all administrations of the MAYSI-2 between 2007 to 2018. Among these, 909 males completed the MAYSI-2 three or more times. Single and multiple group longitudinal invariance tests were conducted using a weighted least squares mean and variance adjusted estimation in order to determine measurement equivalence across multiple administrations. Increasingly restrictive constraints for configural, metric, and scalar invariance models across Time 1 and Time 3 as well as models constraining latent means and variances to be equal across Time 1 and Time 3 all fit these data well. The established seven factor structure for the MAYSI-2 fit the data as well. However, some differences were noted in item level functioning across multiple administrations. The results of the current study suggest that multiple administrations of the MAYSI-2 may not exhibit equivalent measurement properties over time. Consistency of the measurement properties of the MAYSI-2 over time is essential for evaluating changes in mental health. Given that contact with the juvenile justice system has the potential to worsen symptoms of mental illness, caution is warranted when using the MAYSI-2 to assess change.

多项研究表明，马萨诸塞州青年筛查工具第二版（MAYSI-2）具有很强的有效性和可靠性。涉及司法的年轻人经常被反复进行MAYSI-2的管理。该目的本研究的目的是测试多次使用MAYSI-2的男性随时间变化的测量属性的等效性。存档数据取自犹他州少年司法服务管理局，该局由2007年至2018年之间的MAYSI-2所有主管部门组成。其中，有909名男性完成了MAYSI-2的测试达到或超过了3次。使用加权最小二乘均值和方差调整后的估计进行单组和多组纵向不变性测试，以便确定多次给药之间的测量当量。对于时间1和时间3上的配置，度量和标量不变性模型以及将潜在均值和方差在时间1和时间3上相等的模型，越来越严格的约束条件都很好地适合了这些数据。为MAYSI-2建立的七因素结构也适合数据。但是，在多个主管部门的项目级别功能上注意到了一些差异。当前研究的结果表明，MAYSI-2的多次给药可能不会随时间显示出等效的测量特性。MAYSI-2随时间变化的测量属性的一致性对于评估心理健康的变化至关重要。鉴于与少年司法系统的接触有可能加剧精神疾病的症状，因此在使用MAYSI-2评估变化时应格外小心。当前研究的结果表明，MAYSI-2的多次给药可能不会随时间显示出等效的测量特性。MAYSI-2随时间变化的测量属性的一致性对于评估心理健康的变化至关重要。鉴于与少年司法系统的接触有可能加剧精神疾病的症状，因此在使用MAYSI-2评估变化时应格外小心。当前研究的结果表明，MAYSI-2的多次给药可能不会随时间显示出等效的测量特性。MAYSI-2随时间变化的测量属性的一致性对于评估心理健康的变化至关重要。鉴于与青少年司法系统的接触有可能加剧精神疾病的症状，因此在使用MAYSI-2评估变化时应格外小心。
