Multidimensional effects of acculturation on English-language neuropsychological test performance among HIV+ Caribbean Latinas/os.
ABSTRACT Acculturation has been linked to neuropsychological performance in several ethnic groups. However, research among Latina/o samples has examined primarily Mexicans/Mexican Americans and has not examined Latina/o clinical populations of Caribbean descent. This study examined associations between a multidimensional acculturation measure and neuropsychological performance among 82 HIV+ Caribbean Latina/o adults. Multivariate results showed that US acculturation significantly predicted 11-14% of the variance in global neuropsychological functioning, verbal fluency, and processing speed, whereas Latina/o acculturation predicted 6-8% of the variance in motor and executive function (trend level associations). Both linguistic and nonlinguistic cultural factors had distinct effects on neuropsychological performance.

ABSTRACT: The purpose of the current study was to examine the predictive roles of stereotype threat and perceived discrimination and the mediating role of examiner-examinee racial discordance on neuropsychological performance in a non-clinical sample of African American and Caucasian individuals. Ninety-two African American (n = 45) and Caucasian (n = 47) adults were randomly assigned to either a stereotype threat or non-threat condition. Within each condition, participants were randomly assigned to either a same race or different race examiner. All participants underwent neuropsychological testing and completed a measure of perceived discrimination. African Americans in the stereotype threat condition performed significantly worse on global NP (Mz = -.30, 95% confidence interval [CI] [-0.07, -0.67] than African Americans in the non-threat condition (Mz = 0.09, CI [0.15, 0.33]. African Americans who reported high levels of perceived discrimination performed significantly worse on memory tests when tested by an examiner of a different race, Mz = -1.19, 95% CI [-1.78, -.54], than African Americans who were tested by an examiner of the same race, Mz = 0.24, 95% CI [-0.24, 0.72]. The current study underscores the importance of considering the role of contextual variables in neuropsychological performance, as these variables may obscure the validity of results among certain racial/ethnic groups.
