The Swanson, Nolan, and Pelham Rating Scale (SNAP-IV) is a widely used scale that measures the core symptoms of attention deficit hyperactivity disorder (ADHD). However, there are contradictory findings regarding factor structure. Factor structure and measurement equivalence/invariance analysis on parent and teacher SNAP-IV for children referred for an ADHD assessment ( = 250; 6-17 years), revealed a two-factor structure provided the best fit. SNAP-IV scores were also compared with clinician diagnosis of ADHD and research diagnoses of ADHD and hyperkinetic disorder. Parent ratings of inattention and hyperactivity/impulsivity were good predictors of research but not clinician diagnosis. For teacher ratings, only hyperactivity/impulsivity scores were associated with research and clinician diagnosis. SNAP-IV scores showed high sensitivity but low specificity to clinician diagnosis. The SNAP-IV is a valid outcome measure for use in randomized controlled trials and clinical settings, and is best used as a screening rather than a diagnostic tool for ADHD.
斯旺森、诺兰和佩勒姆评定量表（SNAP-IV）是一种广泛使用的量表，用于测量注意力缺陷多动障碍（ADHD）的核心症状。然而，关于因子结构存在相互矛盾的研究结果。对因ADHD评估而转诊的儿童（n = 250；6 - 17岁）的家长版和教师版SNAP-IV进行因子结构和测量等效性/不变性分析，结果显示两因素结构拟合最佳。还将SNAP-IV分数与ADHD的临床诊断以及ADHD和多动障碍的研究诊断进行了比较。家长对注意力不集中和多动/冲动的评分是研究诊断的良好预测指标，但不是临床诊断的良好预测指标。对于教师评分，只有多动/冲动分数与研究诊断和临床诊断相关。SNAP-IV分数对临床诊断显示出高敏感性但低特异性。SNAP-IV是用于随机对照试验和临床环境的有效结局指标，最好用作ADHD的筛查工具而非诊断工具。
