This book lays out the reasons why we should study cognitive development in adulthood, and presents the history, latest data, and results from the Seattle Longitudinal Study (SLS), which now extends to over forty-five years. The SLS is organized around five questions: does intelligence change uniformly throughout adulthood, or are there different life-course-ability patterns? At what age and at what magnitude can decrement in ability be reliably detected? What are the patterns and magnitude of generational differences? What accounts for individual differences in age-related change in adulthood? Can the intellectual decline that increases with age be reversed by educational intervention? Based on work on the SLS, this book presents a conceptual model. The model represents this book's author's view on the factors that influence cognitive development throughout the human lifespan, and provides a rationale for the various influences that have been investigated — genetic factors, early and current family environment, life styles, the experience of chronic disease, and various personality attributes. The data in this volume include the 1998 longitudinal cycle of the SLS. In light of both new data and revised analyses, psychometric and neuropsychological assessments have been linked in long-term data to aid in the early identification of risk for dementia in later life. The book also presents new data and concludes on the impact of personality on cognition. It includes correlation matrices and web-access information for select data sets.

Immigrant caregivers support the aging population, yet their own needs are often neglected. Mobile technology-facilitated interventions can promote caregiver health by providing easy access to self-care materials. This study employed a design thinking framework to examine Chinese immigrant caregivers' (CICs) unmet self-care needs and co-design an app for promoting self-care with CICs. Nineteen semi-structured interviews were conducted in conceptual design and prototype co-design phases. Participants reported unmet self-care needs influenced by psychological and social barriers, immigrant status, and caregiving tasks. They expressed the need to learn to keep healthy boundaries with the care recipient and respond to emergencies. Gaining knowledge was the main benefit that drew CICs' interest in using the self-care app. However, potential barriers to use included issues of curriculum design, technology anxiety, limited free time, and caregiving burdens. The co-design process appears to be beneficial in having participants voice both barriers and preferences.

Public libraries are community hubs that can both create opportunities and address challenges often associated with later life and population aging. Using a thematic analysis of 18 in-depth interviews with public librarians, this study investigates common practices and challenges experienced while developing programs for older adults. This analysis is augmented by an environmental scan of older-adult programming offered in member libraries of the Canadian Urban Library Council (CULC). Results indicate that public librarians leverage community partnerships and staff training to develop programs that foster digital, financial, language, and health literacy and create opportunities for both intergenerational and peer social connection. At the same time, they face challenges related to limited space, budgets, and staff capacity, difficulty meeting the extensive and often conflicting interests of various groups within the library, and marketing programming to older adults. Findings indicate that public libraries may be key players in mitigating challenges often associated with having an aging population, and indeed highlight the many benefits of valuing and providing services to this population.

Inadequate public transportation was recognized as a barrier to social participation, especially for older adults in rural communities and with mobility issues. Older adults will not benefit from opportunities to engage with their community and maintain social networks if they are unable to access them. The purpose of this scoping review was to make recommendations for further research and to summarize areas for improvement identified in the literature that will aid in the development of public transportation initiatives that can better address social isolation for older adults (≥ 55 years of age). Nineteen articles met the inclusion criteria, identifying themes of access to rural public transportation, issues with public transportation, and mobility. In practice, older adults need to prepare for driving cessation and mobility transitions; sound policy requires input to tailor transportation initiatives to an aging population, and future research should explore older adults’ transportation needs and potential solutions in urban and rural communities.

Interprofessional collaboration is understood to improve efficiencies and quality of care but is associated with challenges such as professionals’ differing routines, knowledge, and identities, as well as professional hierarchies and time constraints. Given these challenges, there is limited understanding of how professionals collaborate effectively in providing patient-centred care. This study, with a convergence triangulation mixed-methods study design, explored interprofessional staffs’ perceptions of interprofessional collaboration and patient-centred care when working with hospitalized older adults. Thirty-six staff responded to a survey which included the Patient-Centred Care measure and the Modified Index of Interdisciplinary Collaboration; we also interviewed 14 nursing staff. Although all scores suggested a high value was placed on interprofessional collaboration, scores were low related to activities that facilitated team processes. We identified three themes from the data: knowing the patient/family, functional needs, and communication processes. Staff identified daily rounds with interprofessional teams as supportive of interprofessional collaboration and patient-centred-care.

The COVID-19 global crisis is reshaping Canadian society in unexpected and profound ways. The significantly higher morbidity and mortality risks by age suggest that this is largely a “gero-pandemic,” which has thrust the field of aging onto center stage. This editorial emphasizes that vulnerable older adults are also those most affected by COVID-19 in terms of infection risk, negative health effects, and the potential deleterious outcomes on a range of social, psychological, and economic contexts – from ageism to social isolation. We also contend that the pathogenic analysis of this pandemic needs to be balanced with a salutogenic approach that examines the positive adaptation of people, systems and society, termed COVID-19 resilience. This begs the question: how and why do some older adults and communities adapt and thrive better than others? This examination will lead to the identification and response to research and data gaps, challenges, and innovative opportunities as we plan for a future in which COVID-19 has become another endemic infection in the growing list of emerging and re-emerging pathogens.
