Introduction:

In research, a simple measure of general cognitive ability is often required. One method is the Matrix Matching Test, a brief, free-to-use, language-free assessment of general cognitive ability or intelligence in adults, which taps both fluid and crystalized processes. We investigated its reliability and validity with adolescent participants.

Method:

The Matrix Matching Test was administered to 111 participants, aged 12 to 17 (46% female). Subsamples also completed two standard measures of cognitive ability: Vocabulary (crystalized) and Matrix Reasoning (fluid) tests from the Wechsler Intelligence Scale for Children IV (WISC-IV).

Results:

The Matrix Matching Test was found to have acceptable internal consistency and good retest reliability. Criterion validity was indicated by its ability to distinguish between psychosocially deprived participants living in foster care (n = 40) and controls, and by its positive correlation with grade point average. There were large positive correlations between the Matrix Matching Test and the standard measures of Vocabulary, and Matrix Reasoning, suggesting convergent validity.

Conclusions:

Our preliminary evidence suggests that The Matrix Matching Test is a reliable and valid measure of general cognitive ability for ages 12 to 17.
