The increase of dementia in older adults is changing how medical care is delivered. Recognizing symptoms of pain, managing behaviors, and providing quality of life for people who have advanced dementia requires a new skill set for caregivers. Researchers in this study targeted nurse aide students to test an educational module's effect on students' perceptions of dementia and their ability to care for patients with dementia. The results indicated the training was effective regarding nurse aides' understanding of residual cognitive abilities and need for meaningful contact among patients with advanced dementia; however, the training was not successful in terms of nurse aides' comfort level or perceived skills in working with this population of patients. The findings suggest a need to transform how caregivers are trained in communication techniques. Incorporating this training into nurse aide education has the potential to increase quality of life for people with dementia.
Previous research has revealed various relationships between self-reported personality traits and specific variations in genes influencing serotonergic and dopaminergic pathways. In recent studies, however, personality was repeatedly assessed by the use of more indirect measures, such as the implicit association test (IAT). This tool is assumed to access automatic associations, reflecting the sum of former dispositional behavior and experience. The present study aimed to identify potential genetic effects on personality-related associations measured by the IAT. In a sample of 96 women we found correlations between genetic variations of the serotonin and dopamine transporters (5-HTTLPR and DAT 3’-VNTR) and indirectly measured traits of anxiety and agentic extraversion. In detail, the 5-HTTLPR was linked to the anxiety IAT, whereas the DAT 3-’VNTR was associated with performance in the agentic-extraversion IAT. These findings point out genetic influences on personality-related associations and emphasize the usefulness of the IAT in research on the biological foundations of dispositions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
