Intellectual disability (ID) is a developmental disorder characterized by deficits in intellectual functioning and adaptive behavior. The fifth edition of the Diagnostic and statistical manual of mental disorders (DSM-5) defines adaptive functioning as a severity measure of ID. The availability of tests in the international context to assess this construct has increased in recent years. In Brazil, however, non-systematic assessment of adaptive functioning, such as through observation and interviews, still predominates. The Escala de Funcionamento Adaptativo para Deficiência Intelectual EFA-DI [Adaptive Functioning Scale for Intellectual Disabilities] is a new instrument developed in Brazil to assess the adaptive functioning of 7- to 15-year-old children and support the diagnosis of ID. This study's objectives were to investigate evidence of validity related to the EFA-DI's internal structure, criterion validity, and reliability. The psychometric analyses involved two statistical modeling types, confirmatory factor analysis (CFA) and item response theory analysis (IRT). These results highlight the EFA-DI scale's strong psychometric properties and support its use as a parental report measure of young children's adaptive functioning. Future studies will be conducted to develop norms of interpretation for the EFA-DI. This study is expected to contribute to the fields of psychological assessment and child development in Brazil.
智力残疾（ID）是一种发育障碍，其特征是智力功能和适应性行为存在缺陷。《精神疾病诊断与统计手册》第五版（DSM-5）将适应性功能定义为智力残疾的严重程度衡量标准。近年来，国际上用于评估这一概念的测试有所增加。然而，在巴西，对适应性功能的非系统性评估，如通过观察和访谈进行的评估，仍然占主导地位。《智力残疾适应性功能量表》（Escala de Funcionamento Adaptativo para Deficiência Intelectual EFA-DI）是巴西开发的一种新工具，用于评估7至15岁儿童的适应性功能，并辅助智力残疾的诊断。本研究的目的是调查与EFA-DI的内部结构、效标效度和信度相关的效度证据。心理测量分析涉及两种统计建模类型，即验证性因素分析（CFA）和项目反应理论分析（IRT）。这些结果突出了EFA-DI量表强大的心理测量特性，并支持将其用作幼儿适应性功能的家长报告测量工具。未来将开展研究以制定EFA-DI的解释规范。预计本研究将为巴西的心理评估和儿童发展领域做出贡献。
