ACOSTA-RODAS, Pamela; RAMOS-GALARZA, Carlos  y  RAMOS, Valentina. Psychometric Properties Of ADHD Rating Scale In School Context. Rev Ecuat Neurol [online]. 2019, vol.28, n.3, pp.33-40. ISSN 2631-2581.


The ADHD Rating Scale IV (ADHD RS IV) is one of the most commonly used scales in attention deficit hyperactivity disorder (ADHD) assessment. Its psychometric properties have been studied in contexts including Europe and North America, however, in Latin America, there is shortage of empirical evidence about validity or reliability reported by teachers on a scholar context. The aim of the research was to analyze the psychometric properties of the ADHD RS IV based on the behavior of students reported by teachers.


Three hundred and forty-five students voluntarily participated in this study (162 men and 183 women), aged between 5 and 15 years (Mage = 10.43, SD = 3.61). As instruments of measurement ADHD RS IV, Perception of Differences Test and Go / No-Go experiment were used. Cronbach's alpha, Pearson correlation and confirmatory factor analysis were applied and analyzed.


In the results it was found that internal consistency coefficient of RS IV ADHD is between .93 and .97. There is a significant statistically correlation between the scale and the number of successes points in the Perception of Differences Test (r = -.55, p = < .001) and mistakes to stimuli no-go (r = .34, p = .002). The classic ADHD model of two factors had good indicators of goodness of fit x 2 (101) = 321.40, p < .001; CFI = .96; RMSEA = .08 (.07 to .09) and SRMR = .04.


The article is finalized highlighting the ADHD RS IV has adequate psychometric properties in order to be applied in the school context.
