Objective:To develop a short version of the Spanish 18-item ADHD-Rating Scale IV.es (sADHD-RS-IV.es) to be used as a potential screening tool in pediatric population.Methods:We recruited 652 subjects, ages 6 to 18 (mean ± SD = 11.14 ± 3.27): 518 patients with ADHD (per DSM-IV criteria); and 134 healthy controls. We performed a stepwise logistic regression to select the best subset of ADHD-RS-IV.es items to create a short-form. We calculated internal consistency reliability (Cronbach’s and ordinal alphas) and diagnostic accuracy using receiver operating characteristic (ROC) curve.Results:Six items were found to enter the stepwise analysis significantly. Internal consistency was high (Cronbach’s alpha = 0.86; ordinal alpha = 0.90) and offered a good concordance with clinician diagnosis and a high discriminatory power (AUC = 0.98) with an optimal cut-off at a score of six points.Conclusions:This shorter questionnaire (six items) was able to discriminate ADHD cases from healthy controls.

开发 ADHD 评定量表-IV.es 的简短版本 (sADHD-RS-IV.es)

目的：开发西班牙 18 项 ADHD 评定量表 IV.es (sADHD-RS-IV.es) 的简短版本，用作儿科人群的潜在筛查工具。方法：我们招募了 652 名 6 岁受试者至 18（平均值 ± SD = 11.14 ± 3.27）：518 名 ADHD 患者（根据 DSM-IV 标准）；和 134 名健康对照。我们执行逐步逻辑回归来选择 ADHD-RS-IV.es 项目的最佳子集来创建简短形式。我们使用受试者工作特征（ROC）曲线计算内部一致性信度（Cronbach's 和序数 alpha）和诊断准确性。结果：发现有 6 个项目显着进入逐步分析。内部一致性很高（Cronbach's alpha = 0.86；序数 alpha = 0.90），与临床医生的诊断具有良好的一致性，并且具有较高的辨别力（AUC = 0.98），最佳截止值为 6 分。结论：这个较短问卷（六个项目）能够区分多动症病例和健康对照。
