Item Disability in older adults(2023-03-31) Covinsky, KennethItem Performance on the Texas Functional Living Scale (TFLS) In Mild Cognitive Impairment(2007-08-08) Binegar, Dani Lyn; Cullum, C. MunroMild cognitive impairment (MCI) describes the transitional state between normal aging and dementia for many individuals, although debate continues over whether MCI represents an initial, separate condition, or if it is, in fact, the earliest presentation of dementia. One criterion for the diagnosis of MCI is an absence of impairment in activities of daily living; however, there is growing evidence that many individuals with MCI have difficulties with some instrumental activities of daily living (IADLs), such as managing finances and medications. The current study examined the performance of individuals diagnosed with MCI and normal control subjects (NC) on a brief, quantifiable measure of IADLs, the Texas Functional Living Scale (TFLS). Additional goals of this study were to examine how the TFLS relates to standard neuropsychological measures of global cognitive function, memory, language, executive functioning, and attention, and to determine whether performance on the TFLS declines over time in MCI. As predicted, the MCI sample (n = 30) scored significantly lower than the NC group (n = 30) on the TFLS total score (t (58) = 2.34, p = .011) and on the TFLS Memory subscale (t (58) = 3.29, p = .002). Performance on the TFLS was significantly correlated with performance on the MMSE (ρ = .26) and The Consortium to Establish a Registry for Alzheimer's Disease neuropsychological battery (CERAD; r = .37). Scores on the TFLS Memory and Communication subscales were also correlated with the CERAD total score (r = .45 and .22, respectively). Across all subjects, the TFLS was associated with standard measures of memory and language (ρ's = .22 to .31). Although the difference did not reach statistical significance, subgroups of MCI and NC were followed over time, and 50% of individuals with MCI declined on the TFLS, compared with 29% of NC sample. These findings suggest that subtle changes in cognitive-related IADLs may be present in individuals with MCI, and that the TFLS is sensitive to such changes.Item Psychometric Properties and Clinical Utility of the Texas Functional Living Scale Short Form in Individuals with Schizophrenia(2013-09-10) Rogers, Kathryn Rayne; Casenave, Gerald W.; Hester, Andrea; Chiu, Chung-YiBACKGROUND: Schizophrenia is a chronic mental disorder presenting with psychotic and cognitive symptoms that lead to impairments in independent living and psychosocial functioning. Individuals with schizophrenia demonstrate cognitive deficits in areas of attention, executive functioning, memory, and language. Additionally, schizophrenia has been associated with impairments in activities of daily living (ADLs) such as toileting and the ability to feed one’s self and instrumental activities of daily living (IADLs) such as taking medication, financial management, communication, and transportation. METHODS: Twenty-six participants diagnosed with schizophrenia or schizoaffective disorders were recruited from the University of Texas Southwestern Medical Center’s Division of Translational Neuroscience of Schizophrenia’s IRB approved Database Registry for Psychotic Disorders and completed a neuropsychological test battery which included the Texas Functional Living Scale (TFLS) and University of California San Diego (UCSD) Performance-based Skills Assessment (UPSA). IBM SPSS Statistics (SPSS v. 19.0) was used to perform Pearson correlation coefficients and multiple regression analyses to identify which subscale(s) of the TFLS had the highest predictive ability for examining IADLs to create a possible short form and to identify which subscales of the TFLS long form have the strongest correlation to neurocognitive measures used in the study. The present pilot study used the Type I error rate at .10; a 90% confidence interval. RESULTS: Results of the analysis indicated that the Time and Money Calculation subscales of the TFLS long form significantly correlated with more neurocognitive measures than the UPSA. Specifically, these two subscales had a higher number of moderate to strong correlations with the neurocognitive measures compared to the UPSA. Results also indicated the TFLS short form to have a stronger correlation with the UPSA (r =.59, p < .003) compared to baseline correlations of the TFLS long form and the UPSA (r = .34, p < .112), which suggests that the Time and Money Calculations subscales of the TFLS can be used as a valid short form of the TFLS in the assessment of IADLS in schizophrenia. DISCUSSION: Overall, the short form of the TFLS appears to be a valuable addition to standard neuropsychological assessment batteries given its numerous correlations with neurocognitive measures. Results also suggest that the TFLS short form is a stronger measure for detecting IADL impairments compared to its original long form and the UPSA.
