Objective: The Colorado Cognitive Assessment (CoCA) was designed to improve upon existing screening tests in a number of ways, including enhanced psychometric properties and minimization of bias across diverse groups. This paper describes the initial validation study of the CoCA, which seeks to describe the test; demonstrate its construct validity; measurement invariance to age, education, sex, and mood symptoms; and compare it to the Montreal Cognitive Assessment (MoCA). Method: Participants included 151 older adults (MAge = 71.21, SD = 8.05) who were administered the CoCA, MoCA, Judgment test from the Neuropsychological Assessment Battery (NAB), 15-item version of the Geriatric Depression Scale (GDS-15), and 10-item version of the Geriatric Anxiety Scale (GAS-10). Results: A single factor confirmatory factor analysis model of the CoCA fit the data well, CFI = 0.955; RMSEA = 0.033. The CoCA’s internal consistency reliability was .84, compared to .74 for the MoCA. The CoCA had stronger disattenuated correlations with the MoCA (r = .79) and NAB Judgment (r = .47) and weaker correlations with the GDS-15 (r = -.36) and GAS-10 (r = -.15), supporting its construct validity. Finally, when analyzed using multiple indicators, multiple causes (MIMIC) modeling, the CoCA showed no evidence of measurement non-invariance, unlike the MoCA. Conclusions: These results provide initial evidence to suggest that the CoCA is a valid cognitive screening tool that offers numerous advantages over the MoCA, including superior psychometric properties and measurement non-invariance. Additional validation and normative studies are warranted.

Background Developmental and behavioral problems are among the most common conditions of childhood. These problems affect 12−16% of children in the United States and 13−18% of children in Indonesia. Early detection of developmental deficits among children requires clinicians to screen with accurate tools. Cognitive function screening in children has been increasingly used in many clinical and educational settings. The School-Years Screening Test for Evaluation of Mental Status-Revised (SYSTEMS-R) is becoming a widely-used, reliable, and valid cognitive screening tool for children aged 4−15 years. Prior to our study, there was no Indonesian language version of the SYSTEMS-R.Objective To determine the reliability of the Indonesian translation of the SYSTEMS-R.Methods A cross-sectional study was conducted in children aged 4−15 years who understood the Indonesian language and did not have neurologic or communication impairments. Data were analysed to determine reliability (internal consistency and inter-rater reliability) of the Indonesian version of SYSTEMS-R. Internal consistency was determined using Cronbach’s alpha formula. Internal consistency is a reflection of inter-item correlation and item-to-total correlation. Inter-rater reliability was determined using the Bland-Altman method.Results This study was conducted on 133 children aged 4−15 years in a kindergarten, elementary, junior high, and senior high school in Bandung. The Indonesian version of SYSTEMS-R had significant internal consistency (Cron bach’s alpha 0.936−0.941), and the scores obtained by two raters had good agreement (difference within mean + 1.96 SD).Conclusion The Indonesian version of SYSTEMS-R is reliable for use as a cognitive screening tool for Indonesian children.

Smell Function

Loss of smell function (Anosmia) is reported to be associated with novel coronavirus disease 2019 (COVID-19) infection. The present study was designed to evaluate the effectiveness of an indigenously developed prototype smell test to identify/diagnose asymptomatic COVID-19 positive individuals. A panel of five different odorants belonging to Indian household with unique and mutually exclusive odor were used to develop prototype kit to test the hypothesis. The developed prototype kit was tested at 2 centers (N=49 and 34) with slight modifications. Simultaneously, the kit was also tested on 55 (N=35 and 20) healthy controls. Our results indicate that otherwise asymptomatic COVID-19 positive individuals were having quantifiable deficit in smell sensation. Interestingly, the variable sensitivity of different odorants was observed in different patients. None of the healthy controls reported difficulty in sensing any of the odorant, whereas, some of healthy controls did misidentify the odorants. Overall, the present study provides a preliminary data that loss in smell sensation for various odorants can be exploited as a quick and affordable screening test to identify infected cases among at risk individuals.
