The Vineland-3 purports to measure three dimensions of adaptive behavior, but empirical evidence pertaining to its structural validity is lacking. In this study, factor analyses were conducted on the standardization sample data for the comprehensive forms within the 11- to 20-year-old age range. Results did not support the three domain structure of the test and indicated domain scores did not add additional information about an individual's adaptive performance that was not already accounted for by the Adaptive Behavior Composite (ABC) score alone. Practitioners assessing adolescents with developmental conditions should consider using the ABC score within a multimethod assessment protocol for the various purposes of adaptive behavior assessment including the identification of intellectual disability.

Vineland-3结构得分的结构有效性和可解释性：对评估具有发育条件的青少年的从业人员的启示。

Vineland-3旨在测量适应行为的三个维度，但缺乏有关其结构有效性的经验证据。在这项研究中，对11到20岁年龄段的综合形式的标准化样本数据进行了因子分析。结果不支持测试的三个域结构，并且所指示的域分数未添加单独的自适应行为综合（ABC）分数尚未解决的有关个人适应能力的其他信息。评估有发育状况的青少年的医生应考虑在多方法评估方案中使用ABC评分，以用于适应性行为评估的各种目的，包括识别智障。
