![]() Validity of the CoCoSc was assessed based on the relationship with the MoCA using Pearson correlation. Individuals with CI and cognitively normal controls were administered the CoCoSc and the Montreal Cognitive Assessment (MoCA). The CoCoSc is a 15-min computerized cognitive screen covering memory, executive functions, orientation, attention and working memory, and prospective memory administered on a touchscreen computer. To develop a self-administered computerized test, namely the "Computerized Cognitive Screen (CoCoSc), Hong Kong version", for screening of individuals with cognitive impairment (CI) in community settings. Wong, Adrian Fong, Ching-Hang Mok, Vincent Chung-Tong Leung, Kam-Tat Tong, Raymond Kai-YuĬomputerized cognitive tests may serve as a preliminary, low-cost method to identify individuals with suspected cognitive impairment in the community.

The HKBC is a brief instrument useful for screening cognitive impairment in older adults and is also useful in populations with low educational level. The performances of MMSE and MoCA in differentiating normal from cognitively impaired subjects are slightly inferior to the HKBC. In the receiving operating characteristic curve analysis of the HKBC in differentiating normal subjects from those with cognitive impairment (mild NCD + major NCD), the area under the curve was 0.955 with an optimal cut-off score of 21/22. The mean MMSE, MoCA, and HKBC scores showed significant differences among the 3 groups of subjects. ![]() In total, 359 subjects were recruited, with 99 normal controls, 132 subjects with major NCD, and 128 with mild NCD. The performance of HKBC in differentiating subjects with major NCD, mild NCD, and normal older people were compared with the clinical diagnosis, as well as the MMSE and MoCA scores. The brief cognitive test, Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA), were administered to the subjects. Three groups of subjects aged 65 or above were recruited after written consent: normal older people recruited in elderly centres, people with mild NCD (neurocognitive disorder), and people with major NCD. A new cognitive test, Hong Kong Brief Cognitive Test (HKBC), was developed based on review of the literature, as well as the views of an expert panel. To develop and examine the validity of a new brief cognitive test with less educational bias for screening cognitive impairment.

Cognitive screening tests are expected to play an increasingly important role in identifying individuals with cognitive impairment and in determining which individuals should be referred for further neuropsychological assessment. Comprehensive neuropsychological assessments are multidimensional in nature and used for purposes such as identifying primary and secondary diagnoses, determining the nature and severity of a person's cognitive difficulties, determining functional limitations, and planning treatment and rehabilitation. ![]() Some screening tests can also be helpful for monitoring treatment outcomes. Screening tests are generally brief and narrow in scope, they can be administered during a routine clinical visit, and they can be helpful for identifying individuals in need of more comprehensive assessment. The purpose of this education paper is to provide information to clinicians, healthcare administrators, and policy developers about the purpose, strengths, and limitations of cognitive screening tests versus comprehensive neuropsychological evaluations. The use of computerized testing as a means for cognitive screening and brief cognitive testing is increasing at a rapid rate. The American Medical Association Current Procedural Panel developed a new billing code making behavioral health screening a reimbursable healthcare service.
