The relationship between IQ, metacognition, and self-perception of quality of life as measured by the Mooney checklist was explored. Participants who were hearing and deaf and hard of hearing (D/HH) were compared using these outcome variables, with gender as an additional grouping variable. Results revealed performances on these measures were significantly correlated. There were significant differences on the Mooney measure in favor of the D/HH group (i.e., participants with hearing loss reported significantly less problems and concerns when compared with participants who had typical hearing). Analyses showed no significant differences between males and females in both groups on the metacognitive test, but males took more time and obtained a lower metacognitive score divided by time compared to females; and males showed no significant differences on the metacognitive test in reaction time, or on the metacognitive test scores divided by time. Results showed females with typical hearing performed significantly better on the three dependent variables derived from the metacognitive instrument. Limitations and suggestions for future research were discussed.
