The reliability of intellectual test results has been investigated by test-retest assessment at short intervals, which leads to doubts about its effective stability, mainly because of the intensity and quickness of socio-cultural and environmental changes in the last decades. This study has aimed at investigating the temporal stability, after a long interval between test-retest, through Goodenough Test (1926/1964) and the Columbia Maturity Mental Scale (CMMS, 1972/1993). We have assessed 60 students (both sexes) at a primary state school, from seven to nine years old, presented learning difficulties. The tests were applied, individually, in two occasions, with an interval of six months between test-retest. It was found a correlation index of 0.631 between the whole scores obtained in two Goodenough Tests (1926/1964) applied. Concerning the CMMS (1972/1993) it was found a correlation index of 0.608 between the age standard results. The indexes obtained have suggested reasonable stability of data, offering technical reliability of children's cognitive assessment.Downloads
