“…Of note, although the two performance-based measures significantly correlated with each other, neither of these measures correlated significantly with the informant-report of IADLs. This is consistent with previous findings of limited correlations between questionnaire and performance-based measures of functional status (e.g., Siedel, in press; Kempen, Steverink, Ormel, & Deeg, 1996; Reuben, Valle, Hays, & Siu, 1995; Schmitter-Edgecombe et al, 2011). In a recent study (Schmitter-Edgecombe et al, 2011), it was suggested that questionnaire and performance-based measures of everyday functioning may tap into different aspects of everyday functioning; that is, knowledge gained from multiple experiences in everyday situations and the individual’s application of everyday problem-solving skills, respectively.…”

The relationship between and the cognitive correlates of several proxy measures of functional status were studied in a population with mild cognitive impairment (MCI). Participants were 51 individuals diagnosed with MCI and 51 cognitively healthy older adults (OA). Participants completed performance-based functional status tests, standardized neuropsychological tests, and performed eight activities of daily living (e.g., watered plants, filled medication dispenser) while under direct observation in a campus apartment. An informant interview about everyday functioning was also conducted. Compared to the OA control group, the MCI group performed more poorly on all proxy measures of everyday functioning. The informant-report of instrumental activities of daily living (IADL) did not correlate with the two performance-based measures; however, both the informant-report IADL and the performance-based everyday problem-solving test correlated with the direct observation measure. After controlling for age and education, cognitive predictors did not explain a significant amount of variance in the performance-based measures; however, performance on a delayed memory task was a unique predictor for the informant-report IADL, and processing speed predicted unique variance for the direct observation score. These findings indicate that differing methods for evaluating functional status are not assessing completely overlapping aspects of everyday functioning in the MCI population.

“…That is, the MCI and OA control groups differed significantly in the number of task parts omitted (not completed) but not in the number of task parts executed inaccurately. This is consistent with recent research that has shown that omission errors are associated with cognitive correlates of episodic memory in individuals with MCI (Schmitter-Edgecombe & Parsey, 2014, and with smaller volume in the hippocampus and medial temporal lobe in dementia patients (Bailey, Kurby, Giovannetti, & Zacks, 2013;Giovannetti, Bettcher, Brennan, Libon, Kessler, et al, 2008;Seidel et al, 2013). Consistent with a role for memory in Amap Task execution, better memory skills as represented by MAS list learning were associated with higher Amap execution accuracy scores for the MCI group.…”

Commissions and Omissions Are Dissociable Aspects of Everyday Action Impairment in Schizophrenia

Prior research using performance-based assessment of functional impairment has informed a novel neuropsychological model of everyday action impairment in dementia in which omission errors (i.e., failure to complete task steps) dissociate from commission errors (i.e., inaccurate performance of task steps) and have unique neuropsychological correlates. However, this model has not been tested in other populations. The present study examined whether this model extends to schizophrenia. Fifty-four individuals with schizophrenia or schizoaffective disorder were administered a neuropsychological protocol and the Naturalistic Action Test (NAT), a performance-based measure of everyday action. A principal component analysis (PCA) was performed to examine the construct(s) comprising everyday action impairment, and correlations between the resultant component(s) and neuropsychological tests were examined. Results showed that omissions and a subset of commissions were distinct components of everyday action. However, results did not support unique associations between these components and specific neuropsychological measures. These findings extend the omission-commission model to schizophrenia and may have important implications for efficient assessment and effective rehabilitation of functional impairment, such as the potential efficacy of targeted interventions for the rehabilitation of omission and commission deficits in everyday functioning. Larger studies with prospective designs are needed to replicate the present preliminary findings.
