The current study describes the development and psychometric properties of a new measure targeting sensitivity to change of core autism spectrum disorder (ASD) symptoms, the Autism Impact Measure (AIM). The AIM uses a 2-week recall period with items rated on two corresponding 5-point scales (frequency and impact). Psychometric properties were examined using a large sample (n = 440) of children with ASD enrolled in the Autism Treatment Network. The exploratory factor analysis indicated four factors and resulted in a 25-item questionnaire with excellent overall model fit. Test-retest reliability, cross-informant reliability, and convergent validity with other measures of ASD symptoms and overall functioning were strong. The AIM is a reliable and valid measure of frequency and impact of core ASD symptoms.
本研究描述了一种针对孤独症谱系障碍（ASD）核心症状变化敏感性的新测量工具——孤独症影响量表（AIM）的开发及其心理测量特性。AIM采用两周回忆期，项目在两个相应的5点量表（频率和影响）上进行评分。使用孤独症治疗网络中440名ASD儿童的大样本对心理测量特性进行了检验。探索性因素分析表明有四个因素，并产生了一个包含25个条目的问卷，整体模型拟合良好。重测信度、不同信息提供者间的信度以及与其他ASD症状和整体功能测量方法的收敛效度都很强。AIM是一种可靠且有效的测量ASD核心症状频率和影响的工具。
