Preparing a persian version of kimberley indigenous cognitive assessment for assessing the cognitive problems of illiterate geriatric patients


Department of Psychiatry, Medical Faculty, Isfahan University of Medical Sciences, Isfahan, Iran


Background: The rate of dementia is increasing rapidly. With the recognized high rate of illiteracy among geriatric patients, preparing an appropriate device for special screening among the low-educated elderly seems to be necessary. The aim of this study is to prepare and assess the psychometric properties of the Persian version of the Kimberley Indigenous Cognitive Assessment (KICA) in Iranian adults, in 2012.
Materials and Methods: One hundred and eighty elders participated in this psychometric study. Ninety patients with dementia according to the Diagnostic and Statistical Manual of Mental Disorders, fourth Edition, Text Revision (DSM-IV-TR) criteria, who had been admitted to Geriatrics and Neurology in some of the private clinics in Esfahan, Iran, in 2012, were selected. The rest of the participants were normal persons with the same demographic characteristics as the dementia group, who were selected from the patients' acquaintances and from the Retired Personnel Organization. The statistical tools were the KICA scale, Mini-Mental State Examination (MMSE), and Modified Mini-Mental State Examination (3MSE).
Results: The best clinical cutoff point of the test was 31, with a sensitivity of 92% and specificity of 88%. The Cronbach's alpha coefficient of KICA was 0.93. Among the KICA's subscales, the maximum Cronbach's alpha coefficient belonged to Praxis (α = 0.933) and the minimum one belonged to Delayed Recall (α = 0.927). The correlation coefficients of the KICA score with MMSE and 3MSE were 0.58 and 0.57, respectively.
Conclusion: The KICA test has been seen to be a reliable and valid tool to assess cognitive impairment in the aged people of Iran. The KICA test can be used as a cognitive assessment test for distinguishing patients with dementia, especially illiterate ones from other healthy people in Iran.
