Preliminary evidence for the Matrix Matching Test as a valid and reliable measure of general cognitive ability in adolescents

Introduction: In research, a simple measure of general cognitive ability is often required. One method the Matrix Matching Test, brief, free-to-use, language-free assessment or intelligence in adults, which taps both fluid and crystalized processes. We investigated its reliability validity with adolescent participants. Method:The Test was administered to 111 participants, aged 12 17 (46% female).Subsamples also completed two standard measures ability: Vocabulary (crystalized) Reasoning (fluid) tests from Wechsler Intelligence Scale for Children IV (WISC-IV). Results: The found have acceptable internal consistency good retest reliability. Criterion indicated by distinguish between psychosocially deprived participants living foster care (n = 40) controls, positive correlation grade point average. There were large correlations Vocabulary, Reasoning, suggesting convergent validity. Conclusions: Our preliminary evidence suggests that reliable valid ages 17.
