“…In terms of the effects of education on the LM scores, our findings were consistent with the findings from the previous studies [13-17,23,24], which showed that poorer performances on the LM subtest were observed in less educated group. In Danish and Italian studies, there was a significant effect of education on performances on the LM [15,16].…”

“…In Danish and Italian studies, there was a significant effect of education on performances on the LM [15,16]. In a Mexican-American study, the level of education was the strongest demographic predictor of the LM I and II performances [17]. A previous study that estimated the influence of education on the LM test in the Korean version of WMS-IV among adults aging between 16 and 69 showed that education was an important determinant for the LM subtest scores and its influence on the LM performance increased as participants got older [24].…”

ObjectiveThe purpose of this study is to identify the demographic variables that are affecting performances on the Logical Memory (LM) subtest included in the Korean version of the Wechsler Memory Scale (WMS)-IV and to provide normative data on the LM subtest for the middle-age and elderly Korean people. MethodsThe participants were 435 non-demented adults aging from 50 to 90 and with the educational level ranging from 0 to 21 years. ResultsAge and education were found to be significantly associated with performance on the LM subtest, while gender effect was not statistically significant. Therefore, we stratified the norm blocks by age and education. Age was divided into three groups: 50–59, 60–74, and 75–90 years. Education was stratified into three groups: 0–8 years, 9–12 years, and 13 years or more. ConclusionThe normative data provided in the current study are expected to be useful in clinical and research settings to detect or define subtle changes in episodic memory in Korean adults and elderly, and can also be used for cross-cultural comparison of verbal episodic memory performance among elderly populations using different languages.

“…Cognitive tests scores used for analysis were scale scores stratified by education and age that were generated for Texas-based Mexican-Americans. [24] Significant differences were indicated when the 2-sided P values were less than .05. The data were analyzed by SPSS version 22 for Windows (SPSS Inc., Chicago, IL).…”

C-reactive protein (CRP) is a biomarker for cardiovascular events and also has been studied as a biomarker for cognitive decline. By the year 2050 the Hispanic population in the United States will reach 106 million, and 65% of those will be of Mexican heritage. The purpose of this study was to evaluate the association between CRP levels and cognitive functioning in a sample of Mexican American older adults. A cross-sectional analysis of data from 328 cognitive normal, Mexican American participants from the community-based Health and Aging Brain Among Latino Elders (HABLE) study were performed. Statistical methods included t -test, chi square, multiple linear regression, and logistic regression modeling. Cognitive performance was measured by the Mini Mental State Examination (MMSE), Logical Memory I and II, Digit Span, FAS, and Animal Naming tests. Age, years of education, gender, diagnostic of hypertension, diabetes, and dyslipidemia were entered in the model as covariates. High CRP levels significantly predicted FAS scores ( B = −0.135, P = .01), even after adjusting for covariates. Education ( B = 0.30, P < .05), and diagnosis of hypertension ( B = −0.12, P = .02) were also independent predictors of FAS scores. Participants with higher CRP levels had greater adjusted odds of poorer performance in the FAS test (OR = 1.75, 95% CI = 1.13–2.72, P = .01) when compared to participants with lower CRP levels. This was also true for participants with hypertension (OR = 2.20, 95% CI = 1.34–3.60, P < .05). Higher CRP levels were not associated with MMSE, logical memory, digit span, and animal naming scores. In conclusion, our study showed a clear association between CRP levels and verbal fluency and executive function in a cognitively normal community-dwelling population of Mexican-Americans.

“…Therefore, when using these tests to estimate the five factors in our model, it is necessary to use CFA to avoid the potentially biasing effects of measurement error. Failing that, application of demographically corrected normative data to the observed scores may help attenuate the effects of systematic bias on the observed test results to some extent [48,49].…”

Introduction The present study sought to investigate the measurement invariance of commonly used neuropsychological tests in an ethnically (Hispanic vs. non-Hispanic) and linguistically (Spanish vs. English) diverse sample. Methods Participants were 736 middle-aged and older adults ( M Age = 62.1, SD = 9.1) assessed at baseline. Measurement invariance testing was performed using multiple-group confirmatory factor analysis. Results A five-factor model (memory, attention/executive functioning/processing speed, language, visuospatial, and motor) fit the data well (CFI = 0.979, RMSEA = 0.047) and the composite reliability of the factors ranged from .76 (visuospatial) to .97 (motor). The five-factor model was found to possess strict measurement invariance for ethnicity and language without a decrement in fit compared to a strong (scalar) invariance model (ΔCFI = .000, ΔRMSEA = .002). Discussion These results indicate that a five-factor model is suitable for estimating cognitive functioning in Mexican Americans and non-Hispanic whites without bias by ethnicity or language.
