PACANARO, Silvia Verônica; SANTOS, Acácia Aparecida Angeli dos  and  SUEHIRO, Adriana Cristina Boulhoça. The validity of the TONI 3 for assessing people with Down Syndrome. Arq. bras. psicol. [online]. 2009, vol.61, n.3, pp. 107-116. ISSN 1809-5267.

This study aimed to identify evidence of validity for the Test of Nonverbal Intelligence - TONI 3 - Form A in the evaluation of the intellectual ability of people with Down Syndrome (DS). It comprises 51 people with the syndrome, of both sexes, ages ranging from 6 to 24 (M=15.3; SD =4.9), coming from institutes for special education in the interior of the state of São Paulo. The test was administered individually and the results showed evidence that confirms the reliability of the TONI 3 - Form A for the assessment of developmental abilities. Similar to what was observed in the normative sample, the average score was higher in subgroups formed by people with higher average age, though there have been oscillations in the score of some age groups in which the people with DS were divided. There was no significant statistical difference between the results obtained with the normative sample and the people with Down Syndrome, which suggests the usefulness of other similar studies, to be carried out with bigger samples, aiming to identify patterns of cognitive ability development in people with Down Syndrome
