“…For establishing the construct validity, significant relationships were detected between MoCA-5-min and various comparing constructs, including age, education and functional ability. However, the relationships between MoCA-5-min with depression and mental wellbeing were not significant, which was contradictory to the hypothesized relationships suggested by the available evidence [39,40].…”

Introduction The prevalence of dementia in Tanzania, as in other developing countries is progressively increasing. Yet international screening instruments for mild cognitive impairment are lacking. The aim of this study was to determine the psychometrics and the diagnostic ability of the Montreal Cognitive Assessment 5 minutes protocol (MoCA-5-min) among older adult in the rural Tanzania. Methods The MoCA-5-min and the IDEA cognitive screening were concurrently administered through face to face to 202 community-dwelling older adults in Chamwino district. Exploratory factor analysis (EFA) using principal component method and oblique rotation was performed to determine the underlying factor structure of the scale. The concurrent, construct as well as predictive validities of the MoCA-5min were examined by comparing its score with IDEA cognitive screening and psychiatrist's diagnosis using DSM-V criteria respectively. Results The EFA found that all the MoCA-5-min items highly loaded into one component, with factor loading ranging from 0.550 to 0.879. The intraclass correlation coefficient for 6 weeks test-retest reliability was 0.85. Its strong significant correlation with the IDEA screening (Pearson's r = 0.614, p < 0.001) demonstrated a good concurrent validity. Using the psychiatrist's rating as the gold standard, MoCA-5-min demonstrated the optimal cutoff score for MCI at 22, which yielded the sensitivity of 80% and specificity of 74%; and dementia at score of 16 giving a sensitivity of 90% and specificity of 80%. Upon stratifying the sample into different age groups, the optimal cutoff scores tended to decrease with the increase in age. Conclusion The MoCA-5-min is reliable and provides a valid and accurate measure of cognitive decline among older population in the rural settings of Tanzania. The use of varying cutoff scores across age groups may ensure more precise discriminatory power of the MoCA-5-min.

“…At the same time, there is some evidence to support the generalizability of findings from PRO linguistic validation studies to Korean speakers residing both in Korea and in the United States. 20 Third, although our sample was quite diverse with respect to tumor type, some specific tumor subgroups, such as those with brain or CNS tumors, were under-represented in the sample. This limitation might be important because patients with those tumors may suffer from cognitive deficits that could affect comprehension of self-report measures.…”

PURPOSE The aim of this study was to translate and linguistically validate a Korean-language version of the US National Cancer Institute’s Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). METHODS All 124 PRO-CTCAE items were translated into Korean (PRO-CTCAE-Korean) using International Society for Pharmacoeconomics and Outcomes Research best practices and linguistically validated in a diverse sample of patients undergoing cancer treatment (n = 120) to determine whether the Korean translation captured the original concepts. During the cognitive interviews, participants first completed approximately 60 PRO-CTCAE-Korean questions and were then interviewed to evaluate the conceptual equivalence of the translation to the original PRO-CTCAE English-language source. Interview probes addressed comprehension, clarity, and ease of judgement. Three rounds of interviews were conducted. Items that met the a priori threshold of 10% or more of respondents with comprehension difficulties were considered for rephrasing and retesting. RESULTS A majority of PRO-CTCAE-Korean items were well comprehended in round 1; 14 items posed comprehension difficulties for at least 10% of respondents in round 1. Four symptom terms (mouth and throat sores, feeling like nothing could cheer you up, frequent urination, and pain, swelling, redness at drug injection or intravenous insertion site) were revised and retested in rounds 2 and 3. For the other 10 symptom terms, no suitable alternative phrasing was identified, and the terms were retested in rounds 2 and 3. After rounds 2 and 3, no item presented difficulties in 20% or more of participants. CONCLUSION PRO-CTCAE-Korean has been linguistically validated for use in Korean-speaking populations. Quantitative evaluation of this new measure to establish its measurement properties and responsiveness in Korean speakers undergoing cancer treatment is in progress.

“…Functional decline also acts as an explicit cue signifying the progressively deteriorating nature of dementia 86 . However, a systematic review 87 indicated that the positive cognitive benefits of most of the studied cognitive training did not always translate into instrumental activity of daily living in people with cognitive impairment 85 . Therefore, incorporating these active strategies to translate acquired cognitive skills into daily activities may explain the superior performance of multimodal interventions.…”

Objectives To conduct a systematic review and network meta‐analysis examining the effects of non‐pharmacological interventions on neuropsychiatric symptoms (NPS) in a community‐dwelling population with preclinical and mild dementia to identify the design characteristics of more effective interventions. Methods A comprehensive search was conducted in 10 electronic databases. Two reviewers independently appraised the methodological quality of studies using the Risk of Bias 2.0 tool. A pairwise meta‐analysis was performed to estimate the standardized mean differences (SMD) with 95% confidence intervals. Network meta‐analysis was then used to estimate the relative effects and rankings of different interventions. Results Twenty‐one studies involving 1773 participants were included. Seven studies focused on preclinical dementia, and 14 studies focused on mild dementia. The majority of studies reported a single domain of NPS (depression, anxiety, apathy or agitation) rather than overall NPS. Data on depression were pooled. Pairwise analysis and network meta‐analysis indicated that multimodal interventions (SMD = −0.47, p = 0.01) were superior to psycho‐behavioral educative interventions (SMD = −0.04; p = 0.65), cognitive training (SMD = −0.27, p = 0.10), and art‐based interventions for improving depression. The more crucial design characteristics included those that emphasized skill transferal into daily life, psycho‐behavioral content to encourage a positive outlook and self‐identity, and disease‐specific educational content to improve symptom management. Conclusions This review indicated that multimodal interventions with cognitive, psycho‐behavioral and educative components were the most effective approaches for improving depression in patients with preclinical and mild dementia. More comprehensive evaluations using standardized and robust measures of NPS in patients with preclinical dementia are warranted.
