Background: The number of older people with cognitive impairment being seen in out patient settings is increasing. A brief screening test, which is culturally and educationally fair, would be very useful for clinicians for identifying dementia in these settings. Objectives: To examine the new cognitive screening test, the Rowland Universal Dementia Assessment Scale (RUDAS), and to compare it with the Mini-Mental State Examination (MMSE). Method: We administered MMSE and RUDAS to 116 subjects, consisting of 58 patients with mild to moderate dementia and 58 age and sex matched controls. The two screening tests were compared with regard to sensitivity and specificity. We looked at the correlation of both tests with years of formal education among the controls. Result: RUDAS had a similar sensitivity but better specificity than MMSE, but did have an educational bias. Conclusions: RUDAS is a useful brief screening test in clinical settings.

Objective: This study explores a personality inventory derived from the results of an indigenous lexical study of personality. From the 272 most commonly used personality descriptors in Khoekhoegowab, the most-spoken of extant Khoesan click languages of southern Africa, an 11-factor model of personality-trait structure was identified. Here, the Khoekhoegowab Personality Inventory (KPI) was created based on those results. Its psychometric properties, the convergent and divergent validity of its scales, and its incremental validity over Big Five and Six traits for predicting physical and mental health, religious practice and attitudes, and income are reported.Methods: Two to five key terms were selected for each of 10 KPI scales: Temperance, Prosocial Diligence, Gossip, Honesty/Morality, Temper, Implacability, Humility, Vanity, Resiliency vs. Agitation, and Courage vs. Fear. These 38 total items were administered to a large sample of adult speakers of Khoekhoegowab in Namibia (N = 632), together with five imported inventories translated into Khoekhoegowab: the 30-item Questionnaire Big Six (QB6), General Self-Reported Health, the Cascades Mental Health Assessment, the Satisfaction with Life Scale, the Duke Religion Index. The properties and intercorrelations of KPI subscales are explored, and their predictive ability for the other variables is compared to that of the QB6.Results: Due to the small number of items on each scale, poor internal consistency was anticipated, but the KPI scales' properties were somewhat better than those of the QB6. R-square change by the inventories as a whole, after accounting for age and gender, indicted that the KPI scales explained more variance than the QB6 scales in almost all criterion variables. Replication of established associations for Big Six traits was mixed: associations were largely as expected for Resiliency, Conscientiousness, and Honesty, but less so for Agreeableness and Extraversion.Conclusions: The KPI had some advantages over the QB6 in predicting physical and mental health. In particular, the four items of Resiliency vs. Agitation predicted lower scores on all physical and mental problem scales. Given psychological-care needs in Namibia, this might be used as a non-intrusive screener. Measurement challenges common to both surveys are discussed, possible solutions, and the utility of higher-order structures are discussed.

According to traditional analysis, Khoekhoe(gowab) makes a tripartite distinction between masculine, feminine, and common gender. Based on a statistical analysis of the comprehensive dictionary by Haacke and Eiseb and the first author’s status as a native speaker, the present paper offers new insights into the gender system of Khoekhoe. This concerns in particular the gender specification across the lexicon, including the status of transnumeral nouns, which leads to a partly revised analysis of the gender system.

This article reports some results of the first large-scale, comprehensive survey of the phonological systems of the Khoisan languages of the Kalahari Basin Area. These languages are famous for their large sets of click phonemes, a typologically rare characteristic otherwise found only in a limited number of languages worldwide. They are also unique because the click phonemes carry a high functional load in terms of phonemic and lexical distinctions in the respective systems. Finally, these languages have strikingly similar and highly skewed root phonotactics. The article provides empirical support for a range of claims and speculations that have been made about these typologically rare systems of the Kalahari Basin Area.
