Community health workers (CHWs) are health professionals that connect the populations they serve to health services. They play a valuable role in assessing patients' needs, linking patients with health and human resources, educating patients toward achieving optimal health, and advocating for their patients to have accessible resources to improve their health and wellbeing. Pharmacies are readily accessible and frequently utilized health locations that could employ CHWs.

Importance: Nationally representative data are critical for understanding the causes, costs, and outcomes associated with dementia and mild cognitive impairment (MCI) in the US and can inform policies aimed at reducing the impact of these conditions on patients, families, and public programs. The nationally representative Health and Retirement Study (HRS) is an essential resource for such data, but the HRS substudy providing dementia diagnostic information was fielded more than 20 years ago and more recent data are needed.

Objective: The Harmonized Cognitive Assessment Protocol (HCAP) was developed to update national estimates of the prevalence of MCI and dementia in the US and examine differences by age, race, ethnicity, and sex.

We conducted an empirical examination of derived relational responding as a generalized operant and concurrently evaluated the validity and efficacy of program items contained in the Promoting the Emergence of Advanced Knowledge - Equivalence (PEAK-E) curriculum. A first study utilized a multiple-baseline across-skills experimental arrangement to determine the efficacy of equivalence-based instruction guided by PEAK-E, replicated across 11 children with autism. A total of 33 individualized skills were taught, and the subsequent emergence of untrained relations was tested throughout the investigation.

Importance: Primary medical and dental clinics may accept fewer people who are deaf as patients than persons who can hear, and clinics may deny requests by patients who are deaf for American Sign Language (ASL) interpretation at appointments when necessary, creating diminished access to primary medical and dental care.

Objective: To compare the rate at which patients who are deaf are offered primary care medical or dental appointments with the rate at which appointments are offered to patients who can hear in a real-world context.

Design, Setting, And Participants: This cross-sectional study used a simulated patient (SP) call audit method.

Introduction: The Harmonized Cognitive Assessment Protocol (HCAP) Project is a substudy within the Health and Retirement Study (HRS), an ongoing nationally representative panel study of about 20,000 adults aged 51 or older in the United States. The HCAP is part of an international research collaboration funded by the National Institute on Aging to better measure and identify cognitive impairment and dementia in representative population-based samples of older adults, in the context of ongoing longitudinal studies of aging in high-, middle-, and low-income countries around the world.

Methods: The HCAP cognitive test battery was designed to measure a range of key cognitive domains affected by cognitive aging (including attention, memory, executive function, language, and visuospatial function) and to allow harmonization and comparisons to other studies in the United States and around the world.

Gratitude has been described as an adaptive evolutionary mechanism that is relevant to healthy psychological and interpersonal outcomes. Questions remain as to whether the presence and benefits of gratitude are consistent from young adulthood to old age; prior research has yielded mixed evidence. We examined the magnitude and direction of age differences in gratitude in three samples (combined = 31,206).

Economic downturns are known to spark periods of increased enrolment in traditional educational pursuits. The current study leverages 30-year longitudinal data from the Longitudinal Study of American Life (LSAL; N=1,556) to examine individual characteristics and experiences in adolescence, just prior to the Great Recession, and during it, to understand why some individuals chose to pursue new education or training in response to the recession whereas others did not. Indicators from adolescence include measures of self-esteem, locus of control, persistence, achievement in mathematics and achievement in science and were collected from 1987 to 1993.

Retirement can be difficult, and experiences vary greatly. Although health, financial status, and family responsibilities have been associated with retirement adjustment, individual psychosocial characteristics may also play a role. Moreover, relatively little is known about the impact of perceived 'job lock'-the belief that retirement is impossible due to financial or health constraints-and its relationship with later retirement adjustment.
