An Investigation of the Criterion Validity of Anadolu Sak Intelligence Scale (ASIS): The Case of EPTS

Abstract

In this study, the criterion validity of the Anadolu-Sak Intelligence Scale (ASIS) was examined within the scope of the identification system of Education Programs for Talented Students (EPTS). The research participant consisted of 153 students. 30 of them were mathematically and scientifically gifted and 123 were non-gifted by the EPTS identification system. Intelligence scores were obtained by ASIS and talent and creativity scores were obtained by Math Ability Test (MAT) and Creative Scientific Ability Test (CSAT). Findings of the study showed that gifted group’s ASIS scores were significantly higher than the non-gifted group’s scores. Participants were divided into three groups (upper 27% middle 46% lower 27%) according EPTS scores and significant differences were found between the average intelligence scores of these three groups [(F(2.128) = 49.361, p< .001; Ƞ2 = 0.435]. To examine the predictive validity of the ASIS, binary logistic regression analysis was conducted and the model correctly classified 84.3% of the participants as gifted and non-gifted. For the ASIS’s concurrent validity significant correlation coefficients were found between the ASIS scores and EPTS, MAT and CSAT scores (rEPTS = .77; rMAT = .72; rCSAT = .55; p <.001). As a result of research findings it can be concluded that ASIS has satisfying criterion validity.
