Objectives: The purpose of this study is to validate a Spanish-language version of the 18-item ADHD Rating Scale-IV ( in a Spanish sample. Methods: From a total sample of 652 children and adolescents aged 6 to 17 years (mean age was 11.14 +/- 3.27), we included 518 who met the DSM-IV-TR criteria for ADHD and 134 healthy controls. To evaluate the factorial structure, validity, and reliability of the scale, we performed a confirmatory factor analysis (CFA) using structural equation modelling on a polychoric correlation matrix and maximum likelihood estimation. The scale's discriminant validity and predictive value were estimated using ROC (receiver operating characteristics) curve analysis. Results: Both the full scale and the subscales of the Spanish-language version of the ADHD-RS-IV showed good internal consistency. Cronbach's alpha was 0.94 for the full scale and >= 0.90 for the subscales, and ordinal alpha was 0.95 and >= 0.90, respectively. CFA showed that a two-factor model (inattention and hyperactivity/impulsivity) provided the best fit for the data. offered good discriminant ability to distinguish between patients with ADHD and controls (AUC = 0.97). Conclusions: The two-factor structure of the Spanish-language version of the ADHD-RS-IV ( is consistent with those of the DSM-IV-TR and DSM-5 as well as with the model-proposed by the author of the original scale. Furthermore, it has good discriminant ability. is therefore a valid and reliable tool for determining presence and severity of ADHD symptoms in the Spanish population.
