The area under ROC was 0.78, p < 0.001 for the CoCoSc total score in differentiating the CI group from the cognitively normal group. Total scores of the CoCoSc and MoCA were significantly correlated (r = 0.71, p < 0.001). Performance on the CoCoSc differed between normal and CI groups in both low and high education subgroups. Seventy-five (46.9%) participants had ≤6 years of education. Receiver operating characteristic curve (ROC) was used to examine the ability of the CoCoSc to differentiate CI from controls.įifty-nine individuals with CI and 101 controls were recruited. 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. Conclusions: Because of the large prevalence of complaints in the population of patients with neurologic deficits and healthy persons alike, and the difficulty in determining the significance of the complaints for the clinical psychological diagnosis/prognosis, it is necessary to expand the research to include biomarkers of brain pathology and other factors.Computerized cognitive tests may serve as a preliminary, low-cost method to identify individuals with suspected cognitive impairment in the community. Older age, male sex, and neurological diseases all increase the likelihood of lower MoCA outcomes. The severity of complaints does not allow us to predict the level of cognitive functions. Results: Groups with different levels of performance in MoCA differed in regards of some cognitive abilities and the severity of complaints related to semantic memory, anxiety associated with a sense of deficit and loss of skills, but provided similar self-assessments regarding the efficiency of episodic memory, long-term memory, social skills and executive functions. ![]() Logistic regression analysis was performed taking into account the independent variables (gender, age, result in PROCOG, DEX-S, and neurological condition) and the dependent variable (dichotomized result in MoCA). We compared these groups according to the severity of the complaints and the results obtained with the other methods. On the basis of the results from the MoCA test, two separate groups were created, one comprising respondents with lower results, and one – those who obtained scores indicating a normal level of cognitive function. ![]() We used the MoCA test, a self-report questionnaire assessing the intensity of cognitive complaints (Patient-Reported Outcomes in Cognitive Impairment – PROCOG and Dysexecutive Questionnaire/Self – DEX-S), and selected subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R PL). Material and methods: The study included 118 adults (58 women and 60 men). Other data, however, do not support the predictive role of complaints, and show no relationship to exist between the complaints and the results of cognitive tests. Some data indicate that cognitive complaints have a predictive value for low scores in standardised tasks, suggesting cognitive dysfunction (e.g. Current reports do not show clear conclusions on this subject. Objective: The aim of the study was to determine whether the intensity of cognitive complaints can, in conjunction with other selected variables, predict the general level of cognitive functions evaluated with the Montreal Cognitive Assessment (MoCA) test.
