Objectives: Students often express uncertainty regarding changing their answers on multiple choice tests despite multiple studies quantitatively showing the benefits of changing answers.
Methods: Data was collected from 86 first-year podiatric medical students over one semester for the course of Biochemistry, as shown in electronic testing data collected via ExamSoft's® Snapshot Viewer. Quantitative analysis was performed comparing frequency of changing answers and whether students changed their answers from incorrect-to-correct, correct-to-incorrect, or incorrect-to-incorrect. A correlation analysis was performed to assess the relationship between the frequency of each type of answer change and class rank. Independent-sample -tests were used to assess differences in the pattern of changing answers amongst the top and bottom performing students in the class.
Results: The correlation between total changes made from correct-to-incorrect per total answer changes and class rank yielded a positive correlation of = 0.218 ( = .048). There was also a positive correlation of = 0.502 ( < .000) observed in the number of incorrect-to-incorrect answer changes per total changes made compared to class rank. A negative correlation of = -0.382 ( < .000) was observed when comparing class rank and the number of changed answers from incorrect-to-correct. While most of the class benefited from changing answers, a significant positive correlation of = 0.467 ( < .000) for percent ultimately incorrect (regardless of number of changes) and class rank was observed.
Conclusion: Analysis revealed that class rank correlated to likelihood of a positive gain from changing answers. Higher ranking students were more likely to gain points from changing their answer compared to lower ranking. Top students changed answers less frequently and changed answers to an ultimately correct answer more often, while bottom students changed answers from an incorrect answer to another incorrect answer more frequently than top students.

Background: Despite an increasing prevalence of Alzheimer's disease and related dementias among Black older adults, large disparities remain in early diagnosis, treatment, and support service referral. Further, services intended to support family caregivers are typically designed around older adult spousal caregivers with little consideration to the wide diversity of families affected by dementia. This qualitative descriptive study examined the caregiving experiences of Black relatives of persons with dementia with the aim of informing the development of more culturally responsive support programming.

Background: Caregivers of people with dementia (PwD) often experience the burden of caregiving and depressive symptoms that may be associated. PwD who experience a higher occurrence of neuropsychiatric symptoms often cause a greater burden on their caregivers due to the difficulty in managing these symptoms. Caregivers may transfer their feelings of frustration and exhaustion with caregiving through the way they communicate with the PwD.

Background: Alzheimer's disease (AD) is a significant health concern affecting at least 10% of individuals aged 65 and older, with heightened risk in Black and Hispanic/Latino populations. Despite this prevalence, our analysis of University of California Los Angeles (UCLA) electronic health records (EHR) indicates that only 4% of patients aged 65 or older receive an AD diagnosis, with underdiagnosis more prevalent among Black and Hispanic/Latino patients compared to their white counterparts. To address this issue, we propose implementing a concise dementia screening tool (DST) in real-world clinical settings.

Residents with dementia living in assisted living settings report that participating in activities contributes to their psychosocial well-being and evidence suggests it has the potential to address outcomes such as improved mood, reduced agitation, and increased feelings of social connection. However, assisted living residents with dementia are infrequently asked about their preferences and interests for activities and those preferences might change over time along with their cognitive or physical abilities. Further it can be challenging for staff to focus on engaging residents in meaningful activity when they have competing demands to perform other care responsibilities.
