Validation of Taiwan Performance-Based Instrumental Activities of Daily Living (TPIADL), a Performance- Based Measurement of Instrumental Activities of Daily Living for Patients with Vascular Cognitive Impairment

Abstract

ObjectivePatients with cerebrovascular diseases often presented both cognitive and physical impairment. Disability in everyday functioning involving cognitive impairment among patients may be hard to completely rely on informants’ reports, as their reports may be confounded with physical impairment. The aim of this study was to validate a performance-based measure of functional assessment, the Taiwan Performance-Based Instrumental Activities of Daily Living (TPIADL), for vascular cognitive impairment (VCI) by examining its psychometric properties and diagnostic accuracy.MethodsNinety-seven patients with cerebrovascular diseases, including 30 with vascular dementia (VaD), 28 with mild cognitive impairment and 39 with no cognitive impairment, and 49 healthy control adults were recruited during study period. The TPIADL, as well as the Mini Mental State Examination (MMSE), Lawton-IADL and Barthel Index (BI), were performed. The internal consistency, convergent and criteria validity of the TPIADL were examined.ResultsCronbach’s alpha of the TPIADL test was 0.84. The TPIADL scores were significantly correlated with the Lawton IADL (r = –0.587, p <0.01). Notably, the TPIADL had a higher correlation coefficient with the cognitive domain of Lawton IADL (r = –0.663) than with physical domain of Lawton IADL (r = –0.541). The area under the relative operating characteristic curve was 0.888 (95% CI = 0.812–0.965) to differentiate VaD from other groups. The optimal cut-off point of the TPIADL for detecting VaD was 6/7, which gives a sensitivity of 73.3% and a specificity of 84.5%.ConclusionThe TPIADL is a brief and sensitive tool for the detection of IADL impairment in patients with VaD.

Adaptation of the Lawton Instrumental Activities of Daily Living Scale to Turkish: Validity and Reliability Study

“…A decline in cognitive function can lead to deficiencies in decision-making ability 30) and subsequent ethical problems in both the clarity of the scale items and in obtaining informed consent. Laudisio et al 4) observed normal and higher cognitive function adequacy in individuals with HMT scores above 7, while Chen et al 31) reported that cognitive disorders negatively affected IADL performance. For these reasons, the present study used HMT scores of ≥ 8 one as an inclusion criterion.…”

Identifying early decline of daily function and its association with physical function in chronic kidney disease: performance-based and self-reported measures

“…Because the assessment has an administration duration of 3–5 min and because only simple test materials are required, the task is suitable for clinical assessment in studies of large samples. It also has an established validity, indicating that the TPIADL is sensitive to impairment ( Chen et al, 2015 , 2016 ).…”

Comparisons of Daily Functional Performance and Relevant Factors in Patients with Alzheimer’s Disease and Subcortical Ischemic Vascular Disease

However, the functional profiles and determining factors in individuals with SIVD have yet to be fully elucidated [18][19][20], and comparisons of these two prevalent subtypes of dementia are even more limited [19][20]. Therefore, the aims of the current study were to compare the profiles of ADL performance between patients with SIVD and AD subtypes, and to analyze predictors of daily functional performance in different subtypes of dementia by examining the associations between clinical factors, cognitive/motor function, and WMHs.…”
