ABSTRACT Consumer‐grade wearables, including smartwatches, fitness trackers, and smart rings, are accessible tools for studying pharmacologic responses in real‐time, monitoring participant health in decentralized clinical trials, optimizing outcome measures, and delivering digital interventions that promote behavior change. However, incorporating consumer wearables into clinical studies is not as straightforward as simply purchasing devices and providing them to participants. It requires engaging with a complex engineering ecosystem with multiple investigator decisions on device selection, associated data management practices, and patient/participant engagement and technical support. This tutorial, based on experience running large clinical trials using consumer wearables, outlines the wearables market landscape across varying form factors and manufacturers as well as the data management software products supporting wearable use. It delineates the major decision processes involved in designing studies that incorporate wearables and presents a structured framework to guide the selection of devices and supporting data tools according to study objectives.

Introduction Sleep is routinely assessed in the management of mental health conditions. Wearable technologies like smartwatches offer a non-intrusive method to quantitatively measure sleep. However, there are limited empirical benchmarks for sleep duration and sleep quality measured by wearables against user reports. This study aims to evaluate the concordance between user-reported and smartwatch-measured hours of sleep and sleep quality. Methods Participants were recruited from two decentralized digital health well-being studies and completed a 7-day sleep diary while simultaneously wearing their smartwatch to sleep (November 7, 2023 - June 30, 2024). Participants self-reported sleep timestamps and perceived sleep quality using the Sleep Quality Scale. Sleep timestamps and quality were also derived from their smartwatches (Garmin Vívoactive 4 2019, Garmin Venu 2 Plus 2022, and Garmin Venu 3/3S 2023). Statistical analyses included paired t-tests, equipercentile linking, and chi-square tests to assess agreement between smartwatch and self-reported sleep parameters. Exploratory analyses established the difference between reported and recorded sleep duration in healthcare shift workers. Results From 841 sleep instances reported by 130 participants wearing three different generation smartwatches, the mean difference in sleep duration between smartwatch-recorded and participant-reported was 21.22 (Garmin Vívoactive), 11.67 (Garmin Venu 2 Plus), and 6.58 (Garmin Venu 3/3S) minutes, respectively. There were statistically significant between-group differences in mean sleep durations assessed by participant self-report vs. Vívoactive 4 smartwatches, but not self-report vs. Venu 2 Plus or Venu 3/3S smartwatches. Equipercentile linking revealed concordance between smartwatch sleep scores and self-reported sleep quality using the Sleep Quality Scale (SQS) between 4 and 7, with disagreements observed at the SQS ranges from 0–4 and 7-10. Conclusions These results suggest that wearables can reliably measure sleep duration, and future research warrants improvements in algorithms that estimate sleep quality with validations across different wearable vendors.

Background Patients with advanced cancer experience a substantial amount of existential and emotional distress. Dignity therapy (DT) is a brief, individualized psychotherapy that aims to relieve existential distress and improve the experiences of individuals impacted by serious illness. Aim To evaluate the feasibility and acceptability of virtual DT (vDT) among patients with advanced cancer. Methods This pilot study recruited adult patients with advanced cancer and an expected prognosis >6 months. The vDT intervention consisted of 2 sessions of guided interviews focused on life review, discussion, and development of a generativity document (GD). Feasibility and acceptability were assessed quantitatively and with semi-structured interviews. Effectiveness measures (distress, dignity impact scale, quality of life [QOL]) were administered pre/post intervention. Results Thirty-one patients referred from a palliative care clinic were eligible. Twenty-one consented and 15 received a final GD. Patients who completed final assessments (N = 9) reported satisfaction with their experience and would recommend the therapy to others. Patients found the virtual component of the intervention acceptable, and the majority noted an improvement in their dignity. Qualitative analysis revealed themes of study team effectiveness, perspectives on intervention processes, benefits to self, and benefits to loved ones. Conclusion Participation in vDT intervention was feasible and acceptable for patients. Patients appreciated the connection with the interviewer, the process, and the benefit of having a document to share with loved ones. Preliminary effectiveness data suggest vDT improves sense of dignity.

Abstract Background and Objectives Research has established that unpaid family members, friends, or others who care for persons with dementia (ie, caregivers) may encounter socioemotional and physical health concerns as a consequence of providing extensive assistance. Similarly, caregivers for people living with traumatic brain injury (TBI) often experience a range of stressors and negative mental health outcomes due to care demands. Individuals with TBI often develop Alzheimer’s disease and Alzheimer’s disease-related dementia (AD/ADRD). This history of TBI may introduce complications to AD/ADRD caregiving. A comprehensive intervention grounded in the understanding of the complex caregiving context of both diagnoses is warranted to address the unique needs and concerns of TBI-AD/ADRD caregivers. Research Design and Methods This study evaluated the feasibility of the TBI-AD/ADRD Caregiver Support Intervention (TACSI) psychoeducational program, designed to support the unique subset of caregivers facing the challenge of assisting relatives with AD/ADRD and a history of TBI. TACSI, a 6-session telehealth intervention, provides tailored psychosocial and psychoeducational coaching. In partnership with the 2 national healthcare centers, 15 caregivers enrolled in the 3-month feasibility study evaluating the design and subsequent refinement of TACSI. Mixed methods data were collected from 3-month follow-up surveys and qualitative data from postintervention interviews. Results The feasibility, utility, and acceptance of TACSI were established. Caregivers liked the telehealth delivery and the personalized nature of TACSI, yet some expressed it would have been more beneficial earlier in their caregiving journey. Discussion and Implications Caregivers valued the TACSI program. Their feedback has been applied to improve TACSI content and delivery for a larger pilot randomized controlled trial that is currently underway.

ABSTRACT Adherence in digital health studies with extended observation periods (≥ 12 months) is limited, and participant retention considerably reduces with time. The US Food and Drug Administration has issued guidelines for improving participant engagement, adherence, and diversity in digital health studies combined with decentralized procedures. A decentralized digital health study on well‐being was designed with protocolized procedures to study the feasibility of participant engagement and technology support to facilitate adherence (wearing the smartwatch ≥ 70% of time) sustained over a 12‐month period. At the end of the study, participants were asked about their ease of participation and free‐response questions about how wearing the smartwatches impacted their physical wellness. An inductive thematic analysis (ITA) was performed to assess themes of those responses and association with adherence. A total of 298 participants were recruited between 2022 and 2023 ( n = 129 in Cohort A in October 22, n = 169 in Cohort B in April 23), with 23% non‐white participants accrued. Among the 298 participants accrued, 273 (92% of accrued participants) completed the 12‐month study with an average overall adherence of 77.4% (SD = 32.64) wear‐time across 12 months. Median adherence of participants whose responses exemplified an ITA theme encompassing perceived behavior changes in sleep and physical activity was higher than those who did not have a response exemplifying that theme. Conversely, those expressing perceived discomfort or intrusiveness of the smartwatch had a statistically lower adherence. These results highlight the crucial roles of technology support and robust engagement efforts to enable sustained adherence over extended follow‐up periods in decentralized digital health studies.

The objective of this manuscript is to present the protocol of a study aiming to test the effects of Accelerated Resolution Therapy® (ART) on pre-loss grief and prolonged grief among older adult family caregivers. This study also aims to better understand predictors of response to ART®, and cognitive processes that occur among grieving individuals following ART®. Design: The study is a double-blinded, randomized clinical trial. Setting: This study takes place at both inpatient and outpatient palliative care and hospice programs at two Mayo Clinic sites. Participants: Participants include older adult ( ≥ 60 years) immediate family members who are primary caregivers of someone with an advanced illness and life expectancy of less than 12 months. Intervention: Participants are randomized to either the ART® intervention group or the attention control group. In the ART® intervention, caregivers engage in imaginal exposure, lateral eye movements, and imagery rescripting via 4 sessions lasting 1-1.5 hours each. The attention control group receives a standard social work intervention, including education, resources, and active listening, which is matched for time and attention. Both interventions will longitudinally follow caregivers from active caregiving into bereavement. Outcomes Measured: The primary outcomes of pre-loss grief and prolonged grief will be measured with the Pre-Loss Grief 12 item (PG-12-R) before the care recipient’s death, and with the Prolonged Grief-13 (PG-13-R) afterwards.

Abstract Research has established that dementia care partners may encounter socio-emotional and physical health concerns as a consequence of providing dementia care. Similarly, care partners for people living with Traumatic Brain Injury (TBI) often experience a range of stressors and negative mental health outcomes due to their care demands. This study aims to support the unique subset of family care partners facing the challenge of caring for relatives who have both diseases, Alzheimer’s Disease/Alzheimer’s Disease related dementia (AD/ADRD) and a history of TBI. Phase I of this study focused on the design and subsequent refinement of the TBI-AD/ADRD Caregiver Support Intervention (TACSI). TACSI is a six-session telehealth intervention providing tailored psychosocial and psychoeducational coaching. Session topics include education on TBI and dementia, stress management, lifestyle planning, and communication skills. In partnership with the Minneapolis VA and the Mayo Clinic-Rochester, we enrolled 15 care partners for Phase I. Mixed methods data from 3-month follow-up surveys and qualitative data from post-intervention interviews established the feasibility, utility, and acceptance of TACSI. Care partners found the program valuable and would recommend it to others. They reported that TACSI helped with their stress management. Some participants shared that TACSI would provide greater benefit to newer caregivers needing more education on the diseases and/or caregiving. Phase I feedback will be applied to improve TACSI content and delivery for the Phase II randomized controlled trial evaluation. TACSI Phase I utility, acceptance, and feasibility outcomes will be highlighted as well as next steps for evaluation.

Introduction: Medical trainees experience a high degree of stress that predisposes them to burnout. This pilot study tested a scalable approach to deliver a validated resilience program (Stress Management and Resiliency Training (SMART)) among Hematology/Oncology fellows at an academic medical center. Methods: This was a mixed-methods, prospective, single-arm clinical trial involving Hematology/Oncology fellows at Mayo Clinic in Rochester, MN, USA. Four one-hour training sessions were conducted virtually with 26 fellows. Stress, burnout, and emotional resilience were measured at baseline, three months, and six months post-intervention using the Perceived Stress Scale (PSS-10), Maslach Burnout Inventory (MBI-HSS), and Connor-Davidson Resilience Scale (CD-RISC2). Changes in mean scores were assessed using paired t-tests. Feasibility and acceptability data were obtained during a virtual focus group. Results: Statistically significant improvements in mean stress (p = 0.004) and professional achievement (p < 0.001) were seen at three months post-intervention. At six months post-intervention, mean stress (p < 0.001) and professional achievement (p = 0.032) continued to improve, while improvements in emotional exhaustion (p = 0.001) and depersonalization (p < 0.001) also became significant. Focus group participants found the program beneficial and reported improved stress and work performance as a result of participation. Conclusion: Virtual implementation of the SMART program is feasible and resulted in improvements in stress and burnout. Focus group participants found the training beneficial, reporting lower stress and improved work performance.

BACKGROUND: Practice guidelines and research results emphasize the need for dyadic interventions targeting psychosocial outcomes such as depression, anxiety, social function, physical function, and health-related quality of life. Resilience interventions have been proposed as one strategy to influence these outcomes. OBJECTIVE: The objective of this observational pilot study was to determine the feasibility and acceptability of the Resilient Living program among persons with stroke or brain tumor (BT) admitted for comprehensive acute inpatient rehabilitation and/or their family caregivers. A secondary aim was to gather preliminary data to assess the effects of the program on quality of life, stress, anxiety, physical function, sleep disturbance, fatigue, resilience, dyadic coping, and caregiver role overload. METHODS: The Resilient Living program is a psychosocial intervention with a focus on building resilience skills. Feasibility and acceptability outcomes were assessed at the end of the study. Quantitative outcome measures were collected at baseline, 12 weeks, and 6 months post the intervention. RESULTS: Eight patients and eight caregivers completed the study. The intervention was feasible with this population. Participants found the intervention useful and appreciated the flexibility of an online program; however, finding time to engage in it was challenging. Recruitment of eligible patients with acquired brain disorders and their caregivers as a dyad was challenging. CONCLUSION: The study confirms prior research suggesting that interventions targeting resilience are feasible, but larger studies with more rigorous methods are needed to appreciate the influence of resilience interventions in persons with brain disorders and their caregivers. Further research is needed to identify the characteristics of those most likely to benefit from resilience interventions and the optimal timing of such interventions.
