Validity and reliability of the Inductive Reasoning Test for Children - IRTC
This study aimed to search for validity and reliability evidences for 'A and B Forms' of the Inductive Reasoning Test for Children - IRTC. A total of 417 students, both sexes, from 1st to 5th grade, between 6 and 11 years old participated of the study. 'A Form' was administered to 219 children and 'B Form' to 198. The investigation of the internal structure of both forms indicated that the correlations between the items may be explained by a single factor which is understood as inductive reasoning. Appropriate reliability by internal consistency was found, except for the 1st and 2nd grades, and regarding the latter, only on 'B Form'. The results also revealed the sensitivity of IRTC in showing differences in the performance of students attending early versus late grade levels. Despite the favorable data, after the reformulation of some items more research is needed, so that 'A and B Forms' are able to discriminate the performance of children in a greater number of grades.
