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: Notwithstanding its value, there are challenges and limitations to implementing a dysphagia screening tool from a developed contexts in a developing context. The need for a reliable and valid screening tool for dysphagia that considers context, systemic rules and resources was identified to prevent further medical compromise, optimise dysphagia prognosis and ultimately hasten patients’ return to home or work.Methodology: To establish the validity and reliability of the South African dysphagia screening tool (SADS) for acute stroke patients accessing government hospital services. The study was a quantitative, non-experimental, correlational cross-sectional design with a retrospective component. Convenient sampling was used to recruit 18 speech-language therapists and 63 acute stroke patients from three South African government hospitals. The SADS consists of 20 test items and was administered by speech-language therapists. Screening was followed by a diagnostic dysphagia assessment. The administrator of the tool was not involved in completing the diagnostic assessment, to eliminate bias and prevent contamination of results from screener to diagnostic assessment. Sensitivity, validity and efficacy of the screening tool were evaluated against the results of the diagnostic dysphagia assessment. Cohen’s kappa measures determined inter-rater agreement between the results of the SADS and the diagnostic assessment.Results and conclusion: The SADS was proven to be valid and reliable. Cohen’s kappa indicated a high inter-rater reliability and showed high sensitivity and adequate specificity in detecting dysphagia amongst acute stroke patients who were at risk for dysphagia. The SADS was characterised by concurrent, content and face validity. As a first step in establishing contextual appropriateness, the SADS is a valid and reliable screening tool that is sensitive in identifying stroke patients at risk for dysphagia within government hospitals in South Africa.

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.

Purpose This study aims at translating and adapting a common and widely used proxy rated cognitive screening tool – Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) into Hausa language and also to evaluate the instrument’s psychometric properties. Design/methodology/approach IQCODE was translated and adapted using a qualitative process involving experts and the adapted version was then evaluated against a gold standard (Diagnostic and Statistical Manual of Mental Disorder V criteria for neurocognitive disorders) with older adults subjects (N = 100), while its reliability (internal consistency) was also evaluated. Descriptive statistics of mean and frequencies, and inferential statistic of receiver operating curve analysis and Cronbach’s alpha coefficient were used for data analysis at an alpha level set at 0.05. Findings The Hausa IQCODE has a sensitivity value of 73.3%, specificity value of 71.8% and optimal cut-off values of between 3.2 and 3.3. For his adapted instrument the area under the Curve (AUC) curve is 0.79 (95% CI: 0.663–0.919; std. err: 0.066; P = 0.000), and Cronbach’s alpha value of 0.819 was obtained indicating that the adapted instrument has good internal consistency. Research limitations/implications The adapted IQCODE is a valid and reliable proxy based cognitive screening tool for the older adult Hausa speakers in Maiduguri. However, clinician and researcher might want to consider different optimal cut-off points when using this tool to screen or to monitor cognitive changes among older adults. Originality/value This research paper translated and adapted Hausa IQCODE into Hausa language. And it gives information on the validity and reliability of the adapted tool alongside with new optimal cut-off for cognitive screening by proxy among older adult patients in Nigeria.
