This study tested the notion that performances on the IQ test, the Mooney problem checklist as a reflection of quality of life (QoL), and metacognition were intercorrelated. It was also intended to find if there were significant differences between the normally-achieving and the low-achieving participants on the Mooney scale and on the metacognitive instrument (i.e. the metacognitive test, reaction time, and the metacognitive test scores divided by mean reaction time) when controlling for the effect of influencing variables. The results revealed that only the performance of the normally-achieving participants was consistent with the notion stated. The heterogeneity of the low-achieving group was presented as one of the many explanations for the lack of significant association between their performances on the three measures. Overall, the participants with high IQs obtained high scores on the metacognitive test; and the older participants obtained better scores on the metacognitive test and on the metacognitive test scores divided by mean reaction time compared to the younger ones. Analysis showed no significant differences existed between the two participating groups in responding to items on the Mooney scale or the metacognitive instrument when controlling for influencing variables. Insights, discussions, and suggestions for future research were presented.
