Validation of the Dementia Care Assessment Packet-Instrumental Activities of Daily Living

Abstract

ObjectiveWe aimed to evaluate the psychometric properties of the IADL measure included in the Dementia Care Assessment Packet (DCAP-IADL) in dementia patients.MethodsThe study involved 112 dementia patients and 546 controls. The DCAP-IADL was scored in two ways: observed score (OS) and predicted score (PS). The reliability of the DCAP-IADL was evaluated by testing its internal consistency, inter-rater reliability and test-retest reliability. Discriminant validity was evaluated by comparing the mean OS and PS between dementia patients and controls by ANCOVA. Pearson or Spearman correlation analysis was performed with other instruments to assess concurrent validity. Receiver operating characteristics curve analysis was performed to examine diagnostic accuracy.ResultsChronbach's α coefficients of the DCAP-IADL were above 0.7. The values in dementia patients were much higher (OS=0.917, PS=0.927), indicating excellent degrees of internal consistency. Inter-rater reliabilities and test-retest reliabilities were statistically significant (p<0.05). PS exhibited higher reliabilities than OS. The mean OS and PS of dementia patients were significantly higher than those of the non-demented group after controlling for age, sex and education level. The DCAP-IADL was significantly correlated with other IADL instruments and MMSE-KC (p<0.001). Areas under the curves of the DCAP-IADL were above 0.9.ConclusionThe DCAP-IADL is a reliable and valid instrument for evaluating instrumental ability of daily living for the elderly, and may also be useful for screening dementia. Moreover, administering PS may enable the DCAP-IADL to overcome the differences in gender, culture and life style that hinders accurate evaluation of the elderly in previous IADL instruments.

Body mass index, performance on activities of daily living and cognition: analysis in two different populations

“…The KLoSA consists of 7 BADL items, including dressing, washing the face, bathing, eating, getting out of bed, toileting, and bladder/bowel management. All BADL variables from KloSA were dichotomized (not need any help = 0 and any kind of help =1) and summed [19,20].…”

Instrumentos mais utilizados na avaliação da funcionalidade de idosos com demência: uma revisão sistemática

“…O próximo instrumento com maior frequência de utilização foi o Índice de Katz, que foi mais utilizado em estudos que verificaram a influência e relação do declínio da marcha, dos membros superiores e das funções executivas sobre a funcionalidade e outras variáveis, como a qualidade de vida, depressão e ansiedade de pacientes com demência 11,12,23,[30][31][32][33][34] . Também foi utilizada para validação de novos instrumentos, que auxiliam no cuidado de idosos com demência 26,35,36 . Um estudo fez a relação entre o grau de severidade da demência e o nível de consciência de idosos com o grau funcional dos mesmos 20 .…”

Nurse-Led Computerized Cognitive Training for Mild Cognitive Impairment: A Preliminary Study

“…Considering the characteristics of computerized programs conducted using SmartPad, individuals with a hearing or visual impairment (including those with unilateral neglect identified through screening of the star cancellation test, line cancellation test, and line bisection test) and those with a neurological or musculoskeletal disorder that posed a restriction on the ability to operate the touch screen independently were excluded from the study. In addition, to rule out conditions that affect cognitive function, a screening questionnaire was used to exclude individuals with depression, stroke, or Parkinson’s disease (Chan, Hung, Wong, Hu, & Beran, 2000; Jones, Williams, & Meschia, 2001; S. B. Lee et al, 2013).…”
