Research Lab: Lifestyle Redesign for Chronic Conditions (LRCC)
Year of Entry: 2021
I am an occupational science researcher whose work focuses on burnout, organizational culture, and well-being among healthcare workers, with particular attention to primary care and safety-net healthcare systems. Grounded in occupational science and committed to health equity and social justice, my research examines how social relationships, institutional structures, and policy contexts shape occupational engagement, sustainability, and health outcomes for providers and patients.
I use mixed and participatory methodologies to understand burnout as a socially embedded, system-level phenomenon. My dissertation, Networks of Care: Understanding Burnout through Healthcare Culture, integrates quantitative and qualitative evidence to identify protective factors, relational dynamics, and leverage points for organizational change within primary care settings. I am especially committed to participatory action research that centers healthcare workers’ lived experiences and translates findings into actionable, community-informed strategies.
In parallel, my scholarship contributes to the design, adaptation, and evaluation of occupational therapy interventions for chronic conditions in primary care. My published work includes studies on the implementation of Lifestyle Redesign® across diverse practice contexts, the clinical and economic outcomes of a Primary Care Lifestyle Redesign clinical trial for adults with diabetes, and occupational engagement during the COVID-19 pandemic. In my role in the Lifestyle Redesign for Chronic Conditions Lab, I conduct practice-based research to continuously evaluate and strengthen intervention fidelity and ensure contextual fit in real-world healthcare settings.
Across my work, I aim to advance equitable and sustainable healthcare systems by strengthening social connection, collective efficacy, and team-based care models that support both healthcare workers and the communities they serve.

Activity disruption, illness intrusiveness, and life satisfaction in adults with Type 1 diabetes: An ecological momentary assessment study. Journal of Behavioral Medicine.

Illness intrusiveness is a psychological process reflecting the perceived impact of illness-related disruptions on daily life in chronic conditions. Type 1 diabetes (T1D) disrupts daily activities through symptoms, self-care demands, and device use, yet little is known about how these disruptions shape psychosocial well-being. This study examined activity disruptions in adults with T1D using ecological momentary assessment (EMA) and tested whether illness intrusiveness mediates the relationship between activity disruptions and life satisfaction. A total of 196 adults with T1D completed 14 days of momentary activity disruption assessments and follow-up surveys assessing illness intrusiveness and life satisfaction. On average, participants reported disruptions in 11% of momentary daily activities, with notable variation across activity types, racial/ethnic groups, and treatment regimens. Activity disruption significantly predicted greater illness intrusiveness (β = 0.33, p < 0.001), which in turn predicted lower life satisfaction (β = -0.51, p < 0.001). Mediation analysis revealed that illness intrusiveness fully mediated the relationship when adjusted for income. Subtype analyses showed that device-related (indirect effect: β = -0.12, p < 0.001) and symptom-related disruptions (indirect effect: β = -0.12, p = 0.01) were fully mediated, whereas self-care disruptions were not associated with life satisfaction. Findings highlight the value of capturing real-time activity disruptions and suggest that illness intrusiveness may be a key explanatory mechanism linking activity disruption and psychosocial outcomes. Device burden and socioeconomic context emerged as factors shaping these relationships.

Primary care Lifestyle Redesign® clinical trial: Diabetes outcomes, healthcare utilization, and costs. Canadian Journal of Occupational Therapy. https://doi.org/10.1177/00084174261421403 Show abstract
Background. In primary care (PC) clinical, healthcare utilization, and financial outcomes associated with Lifestyle Redesign® Occupational Therapy (LR-OT), a framework that incorporates healthy habits into daily routines, are not well documented in the United States.
Purpose. (a) Compare clinical outcomes, healthcare utilization, and associated cost differences between patients who received LR-OT and a control group. (b) Assess the investment required integrate LR-OT into PC.
Method. LR-OT was integrated into a safety-net PC clinic. In a hybrid effectiveness-implementation clinical trial (#NCT03293914), clinical (glycated hemoglobin A1c [HbA1c], blood pressure, cholesterol, and body mass index) and utilization (outpatient, emergency department [ED], hospital visits) data were extracted from medical records of provider-referred adults with diabetes (HbA1c ≥ 9.0%) who were willing to make lifestyle changes.
Results. Of 155 referred patients, 142 were randomized to LR-OT (n = 73) or a control group (n = 69), and 42 completed eight LR-OT sessions within 6 months. Underpowered clinical outcomes indicated no significant change, with aggregated trends suggesting LR-OT supports sustained cardiometabolic improvement. Savings of $250,518.96 is attributed to LR-OT, driven by significant decreases in ED visits (p = .03) and hospital days (p = .03), despite nonsignificant increases in outpatient utilization. The projected cost-benefit of integrating a full-time LR-OT in PC is $352,326.72 with a 236% return on investment.
Conclusion. Clinical trends and significant reductions in acute care services drove healthcare-wide cost savings, demonstrating clinical and financial value of integrating LR-OT into PC.

Adapting Lifestyle Redesign®: Navigating fidelity and contextual fit across four case examples. Canadian Journal of Occupational Therapy. Advance online publication. https://doi.org/10.1177/00084174251397723 Show abstract
Background. Lifestyle Redesign® occupational therapy (LR-OT) originated in the Well Elderly studies as a preventive intervention for older adults, demonstrating positive health and cost outcomes. Although LR-OT later expanded to chronic condition management and inspired numerous programme adaptations for different contexts and populations, systematic reporting of intervention modifications remains scarce. This gap extends beyond OT, reflecting a broader movement in implementation science.
Purpose. This study applies the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) to systematically document adaptations across four LR-OT programmes. Additionally, we examine fidelity-consistency by mapping programme components to the Well Elderly programme and core LR-OT elements.
Methods. Four teams implementing adapted programmes—diabetic foot ulcer self-management, primary care chronic condition management, Remodeler sa Vie for French-Canadian older adults, and LR weight management—participated in a structured mapping exercise to align programmes with FRAME and LR-OT principle components.
Results. Adaptation approaches varied from highly structured to loosely standardized methods. Despite numerous modifications, all programmes strongly aligned with LR-OT's core characteristics and domains.
Conclusion. This study highlights LR-OT's adaptability across diverse contexts while maintaining fidelity to its foundational framework. Findings contribute to implementation research, providing a model for systematically documenting and characterizing adaptations made to client-centred, evidence-based OT programmes.

Research design and baseline participant characteristics of the Resilient, Empowered, Active Living with Diabetes - Telehealth (REAL-T) Study: A randomized controlled trial for young adults with type 1 diabetes. Contemporary Clinical Trials, 135, 107386. https://doi.org/10.1016/j.cct.2023.107386 Show abstract
Background. Type 1 diabetes (T1D) is a chronic condition affecting nearly 1.9 million people in the United States. Young adults (YAs) with T1D face unique challenges in managing their condition, experiencing poorer health and well-being than other age groups. The current study is evaluating the Resilient, Empowered, Active Living (REAL) intervention, previously shown to improve glucose levels and quality of life among YAs with diabetes, using telehealth delivery (REAL-T) to expand reach and accessibility. This paper reports on the methodology and baseline participant characteristics of the REAL-T study.
Methods. REAL-T is a two-arm randomized controlled trial that recruited 18–30 year olds with T1D via clinics and social media advertising. Data collection, which was adapted to be fully remote due to COVID-19, occurs every three months for one year. Participants receive either usual care or a 6-month telehealth occupational therapy intervention. The primary outcome is glycated hemoglobin (A1c); secondary outcomes include diabetes distress, quality of life, and continuous glucose monitor-derived measures.
Results. The study enrolled a diverse sample of 209 YAs with T1D. Analysis of baseline data indicates equivalence between the intervention and control groups. Study participants have notably higher diabetes distress and poorer mental well-being than similar populations.
Conclusion. The REAL-T study successfully adapted to remote implementation during the COVID-19 pandemic. By examining long-term outcomes, mediating pathways, and cost-effectiveness, the study will contribute knowledge of the impact of tailored interventions for YAs with T1D, designed to reduce disparities and improve health and well-being in this population.

Exploratory analysis of college students’ occupational engagement during COVID-19. Journal of Occupational Science, 29(4), 545–561. https://doi.org/10.1080/14427591.2022.2101021 Show abstract
Introduction. During the COVID-19 pandemic, college students experienced occupational disruptions to their daily routines and alarming mental health outcomes. This paper seeks to examine associations between college students’ occupational engagement and psychological well-being; identify potential protective and risk factors for gender, race, and ethnic identities; and explore the impacts of occupational disruptions during COVID-19.
Method. Undergraduate students (n = 152) were recruited through social media and ResearchMatch and completed an online survey. Associations and differential impacts on identity were analyzed for occupational balance, satisfaction with participation in discretionary activities, depression, fatigue, general anxiety, stress, loneliness, and COVID-19 behaviors, beliefs, and experiences (CBBE).
Results. Occupational engagement had significant negative correlations with the five mental health measures. Females reported more fatigue, anxiety, and stress than males. Hispanic/Latinx participants reported greater occupational engagement. Black/African American participants reported greater occupational balance than their multiracial peers. Occupational Impairment subscale was positively associated with depression, anxiety, and stress. Participants who lost their job were more depressed. Males reported a greater increase in alcohol, cigarette, and recreational drug consumption than females. The COVID-19 Preventative Action subscale was positively correlated with COVID-19 Worry. Females both engaged in more preventive actions and worried more than males.
Conclusion. Overall, this study reveals that increasing occupational engagement during the COVID-19 pandemic could be beneficial for mental health and well-being, that COVID-19 had differential impacts on occupational engagement and mental health outcomes based on identity, and that behaviors, beliefs, and experiences shifted with the global occupational disruption.

Tapia, V. A., Gregorio, A. M., & Thorne, B. (2021). How mindfulness meditation impacts long-term explicit semantic memory. Bronco Scholar. Full text Show abstract
In light of the Coronavirus-19 Pandemic inflicting the world, college students in the United State of America are concerned about their health, the state of the economy, and dramatic lifestyle shifts, and they are experiencing an increased level of stress (Copeland et al., 2020). Stress takes a toll on our cognitive function, which can negatively impact our abilities to store information. Studies have shown that both music and the practice of mindfulness meditation strengthens brain function, which helps to enhance memory (Ferreri et al., 2013; Roozendaal et al., 2009). The current experimental study aimed to provide insight to pinpoint the benefits of how a single meditation along with music could improve memory recall, and their ability to aid one’s cognitive abilities to remember words that are attempted to be stored in memory semantically. Participants were majority female 84.7%, Hispanic or LaxinX 42.4%, between the ages of 18 and 25 83.9%, and at or below poverty level 61.1%. It was expected that participants who listened to background music during encoding and recall as well as engaged in a mindfulness meditation would remember the most words. There were no significant differences in memory recall when participants practiced mindfulness meditations or listened to music F(3)=1.47, P>.05. Additional data collection, or a larger and more generalizable sample, would be necessary to increase the power of this study. This should not discount the individual benefits that both mindfulness meditations and music have independently shown in the past.
