Contextual variation in cognitive performance of older adults: Demonstration of an age-of-examiner effect

Objective: Consistent with research on stereotype threat, when examiners' characteristics make a stereotype of the participant group salient, it can hamper participants' performance. We hypothesized that younger examiners represent a subtle element activating age stereotypes, leading older people to perform worse as examiners' age decreases. Method: We analyzed data from the Survey of Health, Ageing, and Retirement in Europe (SHARE; NParticipants = 32768) and Vivre-Leben-Vivere studies (VLV, Nparticipants = 960), wherein older people were tested at home by examiners of different ages on eight cognitive tasks. Results: Our results indicate that participants' performance on five tasks was positively linked to examiners' age, showing that the older the examiner, the better the participants' performance. Conclusions: These findings could have implications for the current assessment of memory performance among older adults.

A review of recent findings on substance abuse treatment for pregnant women

Recent years have brought an increased interest in the treatment needs of pregnant substance abusers. This article reviews the literature on this subject, providing an overview of what is known about the prevalence of substance abuse during pregnancy; the factors in women's lives, especially pregnant women, that lead to substance abuse and that facilitate and impede treatment success; and the components of successful treatment programs. The prevalence of prenatal illicit drug use is known to be about 5% of all pregnant women nationwide, with higher rates for selected subgroups. Local studies have shown much higher rates. Substance abuse is associated with poverty, with the substance abuse of significant others, and with family violence. Perinatal substance abusers experience poorer birth outcomes. The negative consequences for babies do not stop at birth; home environments may be chaotic and often children are removed from their mother's care if substance abuse continues after birth. While the literature on prevalence, correlates, and outcomes of perinatal substance abuse is plentiful, there continues to be sparse information on successful treatment approaches. Sample sizes are small and there are few studies with adequate comparison groups. The small number of outcome studies we review suggest that, as with the broader treatment literature for other populations, success (as measured by abstinence) is associated with retention. Retention is facilitated by the provision of support services, such as child care, parenting classes, and vocational training. There is no clear empirical basis for concluding that one type of treatment (for example, residential treatment) is more effective than another.
