Cross-Cultural Comparison of Rural Healthy Adults: Russian and American Groups

Abstract Objective The Russian-speaking population is among the largest European-born in the U.S., yet Russian-American cross-cultural research is scarce. Two studies compared neuropsychological test performance in Russian and American urban adults. However, rural populations of the two nations have...

Description
Summary:Abstract Objective The Russian-speaking population is among the largest European-born in the U.S., yet Russian-American cross-cultural research is scarce. Two studies compared neuropsychological test performance in Russian and American urban adults. However, rural populations of the two nations have never been compared. Cross-cultural neuropsychological differences in rural populations might present differently than in urban dwellers. The present study provides a cross-sectional comparison of neuropsychological test performance in Russian and American rural adults. Methods Neuropsychological test performance of 51 American (67% female) and 52 Russian (60% female) healthy rural adults age 18–89 was compared using t-test with Bonferroni correction for education-adjusted z-scores for the following tests: Rey Complex Figure Test (RCFT), Rey Auditory Verbal Learning Test (RAVLT), Trail Making Test A and B (TMT A&B), Stroop Neuropsychological Screening Test, Benton Judgment of Line Orientation Test (JLO), Brief Visuospatial Memory Test-Revised (BVMT-R), Color Trails Test 1 and 2 (CTT 1&2), WMS-IV Logical Memory Test (LMT), WAIS-IV Digit Span Forward (DSF) and Backward Test (DSB), and Symbol Digit Modalities Test (SDMT). Results Age and sex distribution did not differ in the two groups, but the Russian group was more highly educated. The American group outperformed the Russian group on TMT B, CTT 2, recognition trials of RCFT, BVMT-R, LMT, and on DSF. Conclusions Cultural differences in attitudes to timed activities, experience with timed tests and multiple-choice format, attention to details, and length of digit-words that put differential demand on short-term memory in Russian and in English may mediate observed between-group differences.
