Predictors of Retention in the 1Florida Alzheimer's Disease Research Center (ADRC) Over Two Waves.

Attrition is a significant methodological concern in longitudinal studies. Sample loss can limit generalizability and compromise internal validity. Wave one ( = 346) and wave two follow-ups ( = 196) of the 1Florida ADRC clinical core were examined using a 24-month visit window.

Substance use moderates relationships between apolipoprotein E genotype, hepatitis C, cognition, and depression in Miami Adult Studies on HIV (MASH) participants.

The impact of APOE on HIV and HCV disease course, cognition, and memory has been understudied in minoritized populations. This study examined whether scores on cognition and depression measures differed by APOE ε4 carrier status while considering HCV and HIV seropositivity and whether these measures were moderated by substance use. A retrospective analysis examined cognitive and psychological data from participants (n = 493) in the Miami Adult Studies on HIV (MASH) cohort.

Examining the relationship between anxiety and regional brain volumes in the National Alzheimer's Coordinating Center uniform, imaging, and biomarker datasets.

Anxiety has been associated with a greater risk of Alzheimer's disease (AD). Existing research has identified structural differences in regional brain tissue in participants with anxiety, but results have been inconsistent. We sought to determine the association between anxiety and regional brain volumes, and the moderation effect of APOE ε4.

Associations Between Country where Education is Obtained and Cognitive Functioning Among South American and Caribbean Older Adults Living in the U.S.

The increasing prevalence of AD among Hispanics calls for a need for examining factors that affect cognitive functioning and risk of AD among Hispanic older adults. The current study examined cognitive functioning among older Hispanic adults living in the U.S.

Correlations between sleep disturbance and brain structures associated with neurodegeneration in the National Alzheimer's Coordinating Center Uniform Data Set.

This study aimed to 1) determine the association between sleep disturbance and brain structure volumes, 2) the moderation effect of apolipoprotein ε4 genotype on sleep disturbance and brain structures, and 3) the moderation effect of sleep disturbance on cognitive status and regional brain volumes. Using the National Alzheimer's Coordinating Center Uniform Data Set (n = 1,533), multiple linear regressions were used to evaluate the association between sleep disturbance and brain volumes. Sleep disturbance was measured using one question from the NPI-Q.

A Longitudinal Examination of the Association Between Loss of Control and Loneliness Among Older Adults Diagnosed with Cancer.

The objective of this paper is to examine whether feeling a loss of control over one's life is associated with an increased risk for loneliness among those diagnosed with cancer. We draw on data from the Health and Retirement Study to identify three baseline and follow-up cohorts of cancer survivors age 50 and older. Ordinary least squared regression is used to examine predictors for future loneliness.

Examining the Family Support Role of Older Hispanics, African Americans, and Non-Hispanic Whites and Their Breast Cancer Screening Behaviors.

Disparities in breast cancer mortality rates among older Black and Hispanic women are due in part to low participation in cancer screening. Participation in cancer screening could be affected by an array of factors, including social support. Understanding the complex interplay between social support and breast cancer screening among older female adults, specifically among groups with higher mortality rates, is extremely important for timely and appropriate interventions to increase survival rates.

Timing of Immigration Effects Asset Change Among Hispanic Caregivers of Older Family Members.

Given the cultural value of family in Hispanic culture, older Hispanic immigrants are likely to have family caregivers. This study examined the economic implications of caring for older Hispanic adults regarding non-housing financial wealth over time. Using the 2008, 2010, and 2012 waves of the Health and Retirement Study (HRS) and RAND HRS data files, this study compares changes in the non-housing financial wealth between 2008 and 2012 by caregiving and immigration status among Hispanics.

Brief Report: Improving Employment Interview Self-efficacy Among Adults with Autism and Other Developmental Disabilities Using Virtual Interactive Training Agents (ViTA).

This study evaluated the measurable impact of the use of virtual interactive training agents (ViTA) as a way to practice interviewing and gain confidence in responding to questions asked during job interviews. Of the total participants (n = 153), the majority were male (72.55%) with an average age of 21.

The Utility of Cognitive Screeners in the Detection of Dementia Spectrum Disorders in Spanish-Speaking Populations.

Increasing rates of dementia spectrum disorders among Spanish-speaking geriatric populations necessitate the development of culturally appropriate cognitive screening tests that can identify neurodegenerative disorders in their earliest stages when emerging disease-modifying treatments are most likely to be effective. This scoping review identified 26 brief Spanish language cognitive screening tools (<20 minutes) by searching academic databases using a combination of search terms. Results suggest that the Mini-Mental Status Examination and Montreal Cognitive Assessment appear to be less valid than other screeners.
