Establishing And Validating Foundational Competencies In The Application Of Behavioral Gerontology Through Expert Consensus, Alexandra Doran

Dissertations

Behavioral gerontology continues to evolve and grow as an application of behavior analysis, but there remains a critical need to define competencies necessary for behavior analysts to provide ethical, effective care within their scope of competence. This study sought to establish and validate foundational competencies for Board Certified Behavior Analyst s® (BCBA s® ) working in this area. A mixed-methods design using three experiments was used. In Experiment 1, a review of discipline-specific competency frameworks and a job mapping process yielded a preliminary set of behavior-analytic competencies for behavioral gerontology. This produced a preliminary framework consisting of 142 competencies. Experiment …

Older Adults' Caregiving Expectations For The Future, Smita Ekka Dewan, Derek Tice-Brown, Janna C. Heyman, Henry J. Davis, Colette Phipps, Joanne Mcmahon, Laura Sutter, Ye Feng, Jacqueline Heyde

Publications and Research

The purpose of this cross-sectional study was to explore older adults' perception of caregiver stress and their anticipation of becoming a caregiver (N = 723). Bivariate analyses revealed that perceived caregiving stress was higher among older adults who were females, White/Non-Hispanics, with chronic health conditions, who had experienced prior physical and financial caregiving burdens and was lower among those with just a high school degree. Multivariate analyses revealed that perceived caregiving stress levels remained higher only for those with past experience with physical caregiving, those with chronic health conditions, older females and White/Non-Hispanic older adults. The overall model was …

Aging Alone In Malaysia: Social Challenges And Legal Protections, Jal Zabdi Mohd Yusoff, Zulazhar Tahir, Siti Zaharah Jamaluddin

Hasanuddin Law Review

According to The Japan Times, nearly 28,000 elderly individuals in Japan will die alone in the first half of 2024. This alarming trend is not unique to Japan; many countries, including Malaysia, are facing the challenges of an aging population. As Malaysia approaches becoming an aging nation, issues affecting the elderly, particularly those living alone, demand urgent attention. While not all elderly people face the same circumstances, some enjoy stable finances or live with their family, while others live in isolation due to various factors, such as remaining unmarried, widowhood, or estranged familial ties. Some are simply separated by their …

The Role Of Packaging In Smart Home Design, Nour Al Maalouf, Chaiwoo Lee

DRS Biennial Conference Series

As technology becomes vital to aging independently, its first points of contact such as packaging influence accessibility and confidence. This study examines how older adults engage with technology through packaging. Nineteen Boston-based adults aged 65 to 85 interacted with three smart home kit packaging prototypes. Observations and interviews highlighted four main insights: Participants preferred (1) design that supported independent use, (2) visible organization of all components, (3) easy, tool-free opening, and (4) sustainable, recyclable materials. Ninety-five percent recalled past frustration with packaging that felt like it was meant “for someone else.” These results suggest that designing for longevity means rethinking …

Garlic-Derived Metabolite Activates Lkb1, Promotes Adipose Enampt Secretion, And Improves Age-Related Muscle Function Via Hypothalamic Signaling, Jun-Ichiro Suzuki, Kiyoshi Yoshioka, Masahiro Kurita, Takumi Sugimoto, Takahiro Eguchi, Naoki Ito, Aoi Kodama, Yasutomi Kamei, Masahiro Ohtani, Toshiaki Matsutomo, Shin-Ichiro Imai

Garlic (Allium sativum L.) and its aged extract contain many bioactive compounds that can bring health benefits to humans. Among them, S-1-propenyl-L-cysteine (S1PC) has recently drawn significant attention in the field of nutriceutical research. However, the mechanism of its molecular action has remained poorly understood. Here, we show that S1PC significantly activates liver kinase B1 (LKB1) through enhancing its tertiary complex formation with STRAD and MO25, leading to stimulating the phosphorylation of a mammalian NAD

Intrinsic capacity (IC) is defined as the composite of physical and mental abilities an individual possesses, encompassing 5 domains: cognition, psychological health, sensory function, vitality, and locomotion. This construct is central to the World Health Organization’s framework for assessing functional ability in older adults. Growing evidence highlights the critical role of the musculoskeletal system in maintaining these domains, while conditions such as sarcopenia, osteoporosis, and their coexistence as osteosarcopenia (OS) are increasingly associated with IC decline. This narrative review compiles current evidence on the modulatory role of muscles and bones in IC and the impacts of sarcopenia, osteoporosis, and OS. …

The author's familial history sparked a sense of injustice that would not stay buried, shaping a career path in disability services and access. …

The S.A.V.E. Model Of Biblically-Based Existential Therapy For Residents Of The Assisted Living Facility Casa Di Riposo Sardara In Sardinia, Italy, Gregory K. Cherven

Doctoral Dissertations and Projects

Christian gerontological counseling, a traditionally non-progressive field, is a crucial area of ministry, particularly for older adults in assisted living facilities and nursing homes. At Casa di Riposo Sardara in Sardinia, Italy, many residents aged 70 and older lacked a solid biblical understanding of existence and eternal life, contributing to widespread existential anxiety among this population. To address this issue, the researcher developed the S.A.V.E. (solitude, autonomy, value, eternity) model of biblically based existential therapy. This model targets the four main pillars of existential therapy: meaninglessness, isolation, freedom, and death, offering biblical solutions for each. The approach incorporates positive imagery …

Hearing And Vision Impairment And Cognitive Function In Later Life: A Scoping Review Of Psychosocial Mechanisms, Lea Guelde

Honors Capstones

Introduction: Sensory impairment is one of the most prevalent chronic conditions in later life and has been consistently associated with poorer cognitive outcomes. While prior research has documented associations between sensory loss and global cognitive decline, less attention has been paid to the psychosocial mechanisms that may explain this relationship. Understanding these pathways is essential for identifying modifiable intervention targets. This scoping review mapped and synthesized the existing literature on associations between hearing and vision impairment and cognitive function in adults aged 60 years and older, with a specific focus on psychosocial mechanisms linking sensory function and cognition in later …

Beyond The First Bout: Adaptations To Repeated Injuries Across Physiological And Pathological Conditions, Cory W. Baumann, Christopher P. Ingalls, Kazunori Nosaka, Jarrod A. Call

Research outputs 2022 to 2026

Skeletal muscle exhibits remarkable plasticity following injury, yet most research has focused on responses to a single bout of eccentric contractions. This review addresses adaptations to repeated eccentric contraction–induced injuries across physiological and pathological conditions, with emphasis on insights from preclinical rodent models. In healthy muscle, the repeated bout effect (RBE) reduces strength loss and accelerates recovery after subsequent bouts. However, these adaptations are highly condition dependent. Aging can attenuate the RBE, while dystrophic muscle remains vulnerable to repeated injury despite compensatory remodeling. Other factors, including but not limited to, chronic alcohol intake and malignant hyperthermia can influence these responses, …

Due to the increasing population of older adults, the need for health promotion and wellness-based interventions that support effective participation in their respective occupations is essential. Literature supports that engaging in physical activity, health education, and social participation are critical factors in increasing the quality and longevity of life among community-dwelling older adults. A doctoral capstone project was conducted at a community-based day program for low-income older adults to promote wellness, engagement, and continued participation in meaningful occupations.

The purpose of this project was to design and implement group sessions consisting of therapeutic exercise and health education to integrate education, …

Relative Impact Of Multidomain Lifestyle Interventions On Deficit Accumulation Frailty Over 24 Months In The U.S. Pointer Trial, Mark A Espeland, Kayloni Olson, Christy C Tangney, Darren R Gitelman, Maryjo Cleveland, Amber A Thro, Yitbarek N Demesie, Heather M Snyder, Rachel A Whitmer, Pankaja Desai, Rifat Alam, Lucia Crivelli, Thomas M Holland, Olivia Preissle, Rema Raman, Michele K York, Laura D Baker

Faculty, Staff and Students Publications

Background: Multidomain lifestyle interventions hold promise as approaches to slow aging. Deficit accumulation frailty indices (FIs) are increasingly used to capture aging processes. Frailty is highly associated with increased mortality and chronic disease risk, but the degree to which multidomain lifestyle changes impact frailty is not clear.

Methods: The U.S. Study to Protect Brain Health through Lifestyle Intervention to Reduce Risk (U.S. POINTER) was a 2-year randomized clinical trial to compare two multidomain lifestyle interventions designed to increase exercise, improve diet, and promote social and cognitive stimulating activities and health monitoring. The Structured intervention incorporated greater structure, intensity, and accountability …

Simulated Hearing Loss In Healthy Young And Older Adults Results In Poor Reaction Time In Older Adults., Victoria Kowalewski, Nicoleta Bugnariu, Rita M. Patterson, Jessica Hartos

Pacific Journal of Health

Emerging evidence links hearing loss to increased fall risk in older adults, yet mechanisms remain unclear. This study examined the impact of simulated hearing loss on reactive balance control in healthy young and older adults. Participants performed dual-task scenario involving auditory sentence repetition and unexpected surface translations. Hearing loss was simulated using Adobe Audition, applying frequency-specific attenuation based on moderate sensorineural hearing loss levels from the literature.

Speech-in-noise performance significantly declined under simulated hearing loss for both age groups (p < .001), confirming effective simulation, but not significant differences were found between age groups. Maximum COP-COM displacement (the scalar distance between Center of Pressure and Center of Mass) increased with perturbation intensity (Level 1 vs. Level 2: p < .001), but no significant differences were found between hearing conditions or age groups (p > .05), suggesting compensatory step execution was preserved.

Reaction time analysis revealed a significant interaction between hearing condition and perturbation level …

Machine Learning For Elderly Behavior And Risk Incident Modeling, Muhammad Tanveer Jan

Electronic Theses and Dissertations 2020 - Present

The rapid expansion of the aging population presents critical challenges to healthcare systems, particularly in maintaining independent living, ensuring mobility safety, and optimizing emergency interventions. Traditional monitoring solutions are often fragmented, reactive, and hindered by the scarcity of data regarding rare high-risk events. This dissertation proposes a comprehensive, multi-modal machine learning framework designed to model elderly behavior and predict risk incidents across three critical environments: the home, the vehicle, and the clinical setting.

To address the fundamental challenge of class imbalance in medical and behavioral datasets—where risk events are statistically rare—this research first introduces a dual-phase data augmentation strategy. By …

A Qualitative Exploration Of Personal Archiving At The Crossroads Of Ai, Aging, And Documentation, Vanessa Reyes

Proceedings from the Document Academy

As we age, our relationship with our personal archive evolves as we experience cognitive shifts. This is even more so if we experience a reality that is shaped by Artificial Intelligence (AI). AI is increasingly managing personal information through automated curation and personalized AI software interactions tailored to users (Hayes & Downie, 2024), sometimes completely unbeknownst to users. Meanwhile, AI-driven automated curation is also helping older adults manage their archives, influencing their ability to maintain agency over their life documentation practices. Older adults use a variety of health-monitoring technologies, such as the Apple Watch, the Samsung Smartwatch, and the Fitbit. …

Embodied Aging: Older Adults’ Gendered Participation In Physical And Recreational Activity In Assisted Living, Gavin Anderson

Self-Designed Majors Honors Papers

This study examines how older adults interpret their experiences with physical and recreational activity in assisted living, and how these interpretations influence how they engage in their everyday social and physical contexts. In the fall of 2025, eleven older adults—nine women and two men—living in an assisted living facility in a coastal city in Southeastern Connecticut participated in in-depth semi-structured interviews. The facility provides both short-term post-acute care and long-term residential care, offering structured opportunities for physical and recreational engagement.

Past research demonstrates that participation in physical and recreational activity provides substantial benefits for older adults; yet, the lived experience …

A Wellness Approach To Aging, Retirement, And Suicide Risk: Gerontological Considerations, Seth T. Robinson, Derek J. Lee

Adultspan Journal

Suicide risk in older adulthood represents complex interactions between developmental transitions; changing social contexts; and interactions between ecological context and individual perceptions of belongingness, burdensomeness, and hope. This paper presents an integrative,developmentally appropriate framework for conceptualizing and addressing suicide risk in older adulthood, which is grounded in the Indivisible Self model of wellness. Drawing on current empirical knowledge of wellness, suicidality, and older adulthood, this paper presents risk and protective factors associated with older adulthood through life transitions, changing social contexts, and other relevant factors. We present a novel integration of suicide intervention, wellness, and holistic care as a suitable …

Lifetime Tenure, Aging, And Cognitive Decline, David H. Churchwell

Mitchell Hamline Law Review

Aging is a fact of life. We all go through it, and we all experience it. But not all of us are federal judges, and not all of us hold positions of power for life. Aging impacts each of us differently, and there are good reasons to have experienced, elder individuals in roles that benefit from such experience, such as serving as a judge. However, age correlates with an increased prevalence of cognitive decline, and that correlation risks harming the judiciary’s legitimacy. This Article argues that constitutional incentives for federal judges permit lengthy judicial tenures, which increases the risk of …

Multisystem Predictors Of Dynamic Gait Stability Across Fall Risk In Older Adults, Ashwini Kulkarni, Neda Moghim, Ross Gore, Soumya Banerjee, Christopher K. Rhea, Brittany Samulski

Rehabilitation Sciences Faculty Publications

Gait stability arises from interactions between physiological, cognitive, and psychological systems, yet these domains are often assessed in isolation. This study examined multisystem predictors of anteroposterior margin of stability during walking (MoSAP) in community-dwelling older adults. Of 340 participants, 143 were retained after data quality screening (105 females; age: 70.8 ± 7.8 years). Participants completed the Physiological Profile Assessment (PPA), cognitive testing using Montreal Cognitive Assessment (MoCA), fear-of-falling evaluations using Modified Falls Efficacy Scale (MFES) and a biomechanical gait assessment during preferred and fast speeds. Participants were stratified into four PPA-based fall-risk groups: low, mild, moderate, and high risk. MoSAP …

Watching Over Cold Waves: The Influence Of Social And Technology Surveillance On Independent Older Adults’ Safety, S M Ashfaqur Rahman

All Graduate Theses, Dissertations, and Other Capstone Projects

Cold waves pose a recurring and serious hazard for independently living older adults, yet the monitoring arrangements that shape their protective responses remain understudied. This study examined how social surveillance, defined as check-ins and support from family, neighbors, and community contacts, and technological surveillance, defined as weather applications, smart devices, and emergency alert platforms, jointly and independently predicted cold-wave safety behavior. A cross-sectional, exploratory mixed-methods design was employed. One hundred independently living adults aged 65 and older, residing in cold-prone U.S. states, completed a survey measuring monitoring frequency, source trust, perceived autonomy, concern across six cold-wave hazard types, and a …

The Sequence (S) Index As A Marker Of Diminished Step-To-Step Transition Efficiency In Older Adults, Elham Alijanpour, Ashwini Kulkarni, Peter G. Adamczyk, Daniel M. Russell

Rehabilitation Sciences Faculty Publications

Introduction: Age-related declines in walking efficiency are often attributed to musculoskeletal and neuromuscular changes, yet the mechanisms underlying these inefficiencies remain poorly understood. One key contributor is the step-to-step transition (STST), during which the center of mass (CoM) is redirected between limbs. The Sequence (S) index quantifies the temporal overlap between push-off and collision forces during STST, with higher values indicating greater mechanical energy loss. This study investigated whether aging affects STST efficiency, as quantified by the S index, and examined the timing and impulse characteristics underlying observed differences.

Methods: Thirteen young and eleven older healthy adults walked at five …

24-H Circadian Rest-Activity Rhythms And Physical Frailty In Older Adults: A Biopsychosocial Perspective On Sex Differences And Social Capital, Jisu Kim

Theses and Dissertations

Physical frailty is a prevalent geriatric syndrome characterized by age-related decline across multiple physiological systems. Physical frailty is associated with an elevated risk of adverse health outcomes, including chronic disease progression and all-cause mortality, representing a significant and growing public health concern. Disrupted circadian rest-activity rhythms (RARs) are increasingly recognized as clinically meaningful markers of physical frailty in older adults. However, the extent to which biological sex and social determinants of health (SDoH), particularly social capital, contribute to or modify the associations between RARs and physical frailty remains underexplored.

Therefore, this dissertation summarizes the existing literature on age-related changes in …

Childlessness And Health In Middle Age And Older Adulthood: Evidence From Singapore, Christine Ho, Dahye Kim, Rohan Ray, Bussarawan Teerawichitchainan

Research Collection School Of Economics

Health and well-being in mature adulthood are important concerns given the prevalence of individuals aging without children. We exploit two new instruments for childlessness— infertility and the number of childless siblings—and condition our analyses on a rich set of covariates including childhood health and financial status, to investigate the causal relationship between childlessness and health in middle age and older adulthood. Using a nationwide dataset of 1,500 Singaporeans aged 50 and above, we show that OLS underestimates the negativeeffects of childlessness on health. We find that childlessness leads to higher likelihood of poorer self-reported health and mental distress. The results …

Biological Aging Acceleration In Major Depressive Disorder: A Multi-Omics Analysis, Breno Satler Diniz, Shangshu Zhao, Gabin Drouard, Eero Vuoksimaa, Miina Ollikainen, Eric J Lenze, Ming Xu, Richard H Fortinsky, George A Kuchel, Jaakko Kaprio, Chia-Ling Kuo

2020-Current year OA Pubs

Major depressive disorder (MDD) is linked to a higher risk of premature aging, but the mechanisms underlying this association remain unclear. Using data from two population cohorts (UK Biobank and Finnish Twin Cohort), we evaluate the relationship between systemic and organ-specific proteomic and epigenetic aging acceleration and MDD. A lifetime history of MDD was associated with accelerated proteomic aging at both systemic and organ-specific levels-including the brain-in both cohorts, with stronger associations than those observed with systemic epigenetic aging. Systemic and brain-specific proteomic aging acceleration were linked to higher risks of incident MDD and a greater risk of Alzheimer's disease, …

Effects Of Alcohol Exposure On Recognition Memory And Marble-Burying Tasks In Male And Female Aged Mice, Roma Kamat, Tori Burke

The Journal of Purdue Undergraduate Research

Alcohol consumption in aging humans is a risk factor for cognitive impairment. This experiment assessed the effects of binge-like alcohol drinking in aged mice on memory (using the object recognition memory [ORM] task) and on anxiety-and compulsive-like behavior (using the marble-burying task). Subjects were 8 female and 10 male mice, 14–15 months old, selectively bred for low alcohol preference (LAP). Mice consumed either tap water or a 20% alcohol (v/v) solution in tap water through a drinking in the dark (DID) procedure for 4 consecutive days per week, for 3 consecutive weeks. One and 11 days after DID, mice completed …

Dual-Task Exercise Protects Healthy Older Adults Against In-Creased Risk For Dementia: A Controlled Trial, Helen Tatiane Santos Pontes, João Bento-Torres, Naina Yuki Vieira Jardim, Victor Oliveira Da Costa, Josilayne Patricia Ramos Carvalho, Cristovam Wanderley Picanço-Diniz, Natáli Valim Oliver Bento-Torres

Baltic Journal of Health and Physical Activity

Background: Functionality in aging is closely linked to the ability to divide attention during multitasking activities, which are essential for activities of daily life. However, coordination between motor and cognitive simultaneous tasks decreases with age, impairing functional ability and restricting older adults' participation and healthy aging. This study aimed to assess the effects of a multimodal dual-task exercise intervention on motor and cognitive dual-task costs and its potential to mitigate age-related declines in healthy older adults. Materials and Methods: A controlled trial was conducted with community-dwelling older adults assigned to either the Dual-Task Exercise group, which participated in a 24-session …

The Impact Of Education And Awareness In Influencing Lifestyle Behaviors That Prevent And Treat Sarcopenia In Older Adults: A Mixed-Methods Cross-Sectional Research Study, Alan Lynn Jones

Doctoral Dissertations and Projects

This mixed-methods, cross-sectional study assessed the current level of knowledge and awareness among people aged 50 and older about sarcopenia, as well as their willingness to adopt lifestyle changes that could prevent or reverse the condition as they age. The study aimed to determine whether a lack of awareness and knowledge is linked to current lifestyle behaviors that contribute to or protect against the development of the disease. The population included men and women 50 and older, living independently in the community with no prior diagnosis of sarcopenia. The study used a custom-designed questionnaire and semi-structured interviews. A total of …
