To investigate the psychometric properties of the short or multimodal treatment study version of the Swanson, Nolan, and Pelham, Version IV (SNAP-IV) scale, which measures attention-deficit/hyperactivity disorder and oppositional defiant disorder symptoms.
Participants were 765 parents of children from 4 to 16 years old (641 non-attention-deficit/hyperactivity disorder and 124 attention-deficit/hyperactivity disorder children) from Belo Horizonte, Brazil, who reported sociodemographic characteristics and answered the SNAP-IV. Parents of the clinical sample also underwent the K-SADS-PL interview.
Age was significantly associated with SNAP-IV hyperactivity-impulsivity problems (r=-0.14), but not with inattention or oppositional defiant disorder. Sex was a significant influence on attention-deficit/hyperactivity disorder and oppositional defiant disorder severity (all p<0.001), with boys showing higher scores in the full sample, but not within the attention-deficit/hyperactivity disorder group. Exploratory and confirmatory factor analysis supports a three-factor structure of the SNAP-IV scale. Moderate-to-strong correlations were found between SNAP-IV and K-SADS-PL measures. All SNAP-IV scales showed very high internal consistency coefficients (all above 0.91). SNAP-IV inattention scores were the most predictive of attention-deficit/hyperactivity disorder diagnosis (AUC: 0.877 for the averaging rating method and the raw sum method, and 0.874 for the symptom presence/absence method).
The parent SNAP-IV showed good psychometric properties in a Brazilian school and clinical sample.
研究用于测量注意缺陷多动障碍和对立违抗性障碍症状的 Swanson、Nolan 和 Pelham，第 IV 版（SNAP-IV）量表短版或多模式治疗研究版的心理计量学特性。
参与者为来自巴西贝洛奥里藏特的 765 名 4 至 16 岁儿童的父母（641 名非注意缺陷多动障碍儿童和 124 名注意缺陷多动障碍儿童），他们报告了社会人口统计学特征并回答了 SNAP-IV。临床样本的父母还接受了 K-SADS-PL 访谈。
年龄与 SNAP-IV 多动冲动问题显著相关（r=-0.14），但与注意力不集中或对立违抗性障碍无关。性别对注意缺陷多动障碍和对立违抗性障碍严重程度有显著影响（均 p<0.001），全样本中男孩得分较高，但在注意缺陷多动障碍组中并非如此。探索性和验证性因子分析支持 SNAP-IV 量表的三因素结构。SNAP-IV 与 K-SADS-PL 测量之间存在中度至高度相关性。SNAP-IV 量表的所有分量表均显示出非常高的内部一致性系数（均高于 0.91）。SNAP-IV 注意力不集中分数对注意缺陷多动障碍诊断最具预测性（平均评分法和原始总和法的 AUC：0.877，症状存在/不存在法的 AUC：0.874）。
在巴西学校和临床样本中，父母 SNAP-IV 表现出良好的心理计量学特性。
