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.

智力障碍适应功能量表(EFA-DI)的有效性和可靠性证据

智力障碍(ID)是一种发育障碍,其特征是智力功能和适应行为不足。精神疾病诊断和统计手册(DSM-5)的第五版将适应性功能定义为ID的严重程度。近年来,在国际范围内进行评估这种结构的测试的可用性有所增加。然而,在巴西,对适应性功能的非系统性评估(例如通过观察和访谈)仍然占主导地位。Escala de Funcionamento Adaptativo paraDeficiênciaIntelectual EFA-DI(智障适应功能量表)是巴西开发的一种新仪器,用于评估7至15岁儿童的适应功能并支持ID诊断。这项研究的目的是调查与EFA-DI的内部结构,标准有效性和可靠性有关的有效性证据。心理分析涉及两种统计建模类型,确认因素分析(CFA)和项目反应理论分析(IRT)。这些结果突出了EFA-DI量表的强大心理测量特性,并支持将其用作测量幼儿适应功能的父母报告。将进行进一步的研究以制定EFA-DI的解释规范。预期该研究将有助于巴西的心理评估和儿童发展领域。验证性因素分析(CFA)和项目响应理论分析(IRT)。这些结果突出了EFA-DI量表的强大心理测量特性,并支持将其用作测量幼儿适应功能的父母报告。将进行进一步的研究以制定EFA-DI的解释规范。预期该研究将有助于巴西的心理评估和儿童发展领域。验证性因素分析(CFA)和项目响应理论分析(IRT)。这些结果突出了EFA-DI量表的强大心理测量特性,并支持将其用作测量幼儿适应功能的父母报告。将进行进一步的研究以制定EFA-DI的解释规范。预期该研究将有助于巴西的心理评估和儿童发展领域。
