The influence of accuracy of perceptions and neuropsychological functioning on family relationships in adults with persistent mental illness

This study investigated the influence of accuracy of perceptions and neuropsychological functioning on family relationships in adults with persistent mental illness (PMI). Twenty-seven pairs of adults with PMI and their family members participated in this study. Neuropsychological functioning of the adults with PMI was measured using the Wechsler Adult Intelligence Scale - Revised subtests of digit span, block design, arithmetic, digit symbol; the Stroop Color and Word Test, and the Controlled Oral Word Association Test. Performance on each of the six neuropsychological tests was estimated by both the adult with PMI and his or her family member. Accuracy of these ratings was determined by the difference between actual and predicted scores. Family functioning, as reported by all participants, was measured using the Index of Family Relations and eight face-valid family questions. Both groups overestimated the neuropsychological functioning of the adults with PMI Contrary to prediction, the more accurate family members were in predicting overall neuropsychological functioning, the worse they reported their family functioning to be. Implications of these findings are discussed, and future studies are suggested.
