Abstract:
Objective To develop the Non-Language-Based Cognitive Assessment (NLCA) applicable to patients with aphasia and to validate the reliability and validity of NLCA.Methods Seventy-three normal subjects and 32 patients with mild cognitive impairment were evaluated by the NLCA and the Mini-Mental State Examination.Forty subjects were randomly selected from the normal subject samples were assessed with the NLCA,the Auditory Verbal Learning Test,the Rey-Osterrieth Complex Figure Test (Form A),the Stroop Color-Word Interference Test,the Raven's Standard Progressive Matrices (Part A),and the WAIS Digit Span Test.Results The NLCA had high inter-rater agreement (Cronbach's α coefficient 0.836),reliability among the assessors 0.895-0.953,test-retest reliability 0.863-0.952 at at a 2-6 week interval.The years of education was significantly correlated with NLCA (r =0.852,r ＜ 0.01).When the Montreal Cognitive Assessment was used as diagnostic criteria,the area under the receiver operating characteristic curve was 0.899 (95％ confidence interval 0.827-0.972).When cutoff at 70,the NLCA had had high sensitivity,specificity,positive predictive value and negative predictive value in the identification of patients with mild cognitive impairment.Conclusions The NLCA has good reliability and validity.It is an effective cognitive function assessment that meets the basic requirements of the neuropsychological tests.
