本研究的目的是开发和验证成瘾严重性指数多媒体版(ASI-MV®)的计算机自适应测试(CAT)版本，即成瘾严重性CAT。这一目标是分四步实现的。首先，在与药物滥用治疗专家集思广益后，对成瘾严重程度CAT领域的新候选条目进行了评估。接下来，这个新的题库在一个大的非临床样本(n=4419)和物质滥用治疗样本(n=845)上进行了心理测量学评估。根据这些结果，最终项目被选择和校准，以创建成瘾严重程度CAT算法。一旦为整个评估开发了算法，就创建了一个功能齐全的成瘾严重程度猫的原型。进行了CAT模拟，并为成瘾严重程度CAT算法选择了最佳终止标准。最后，通过检验收敛/判别效度和对变化的敏感性来评价CAT算法的结构效度。成瘾严重程度猫被确定为有效、对变化敏感和可靠的。此外，成瘾严重程度猫的服药时间显著少于ASI-MV综合得分的平均服药时间。这项研究代表了基于IRT的成瘾严重性CAT的初步验证，需要对成瘾严重性CAT进行进一步的探索。
The purpose of this study was to develop and validate a computer adaptive testing (CAT) version of the Addiction Severity Index-Multimedia Version (ASI-MV®), the Addiction Severity CAT. This goal was accomplished in four steps. First, new candidate items for Addiction Severity CAT domains were evaluated after brainstorming sessions with experts in substance abuse treatment. Next, this new item bank was psychometrically evaluated on a large non-clinical (n =4419) and substance abuse treatment sample (n =845). Based on these results, final items were selected and calibrated for the creation of the Addiction Severity CAT algorithms. Once the algorithms were developed for the entire assessment, a fully functioning prototype of an Addiction Severity CAT was created. CAT simulations were conducted and optimal termination criteria were selected for the Addiction Severity CAT algorithms. Finally, construct validity of the CAT algorithms was evaluated by examining convergent/discriminant validity and sensitivity to change. The Addiction Severity CAT was determined to be valid, sensitive to change, and reliable. Further, the Addiction Severity CAT’s time of administration was found to be significantly less than the average time of administration for the ASI-MV composite scores. This study represents the initial validation of an IRT-based Addiction Severity CAT, and further exploration of the Addiction Severity CAT is needed.
