Research Assistant Information Sheet

 

Focus and Mission:

 

Our Lab's foci are on the cultural, familial, and behavioral factors that promote wellness and reduce morbidity among families made vulnerable to health inequity, given their positionality amid intersecting ecological systems of privilege/oppression. As a pediatric psychology lab, our mission is to actively promote the health and psychological well-being of all children, youth, families, and communities through our Practice, Education, Advocacy, and Research. 

More specifically, this research includes:

  • Explore cultural, family, and behavioral factors that equitably promote health and reduce morbidity in childhood chronic illness.
  • Develop interventions for youth and their families informed by Multicultural Orientation Framework and Acceptance and Commitment Therapy.
  • Examine models of stress and adaptation to equitability promote health-related quality of life, glycemic health, and diabetes self-management, among adolescents living with diabetes and their families.
  • Integrate quantitative, qualitative, behavioral, and diversity science methodologies to inform, develop, and refine clinical health interventions and assessments to promote health equity.

Current Projects

It is a National Institute on Minority Health and Health Disparities of the National Institutes of Health-funded study to develop an intervention aimed at improving health outcomes in Black youth with type 1 diabetes. The five-year award, "Family mHealth Intervention to Improve Health Outcomes in Black Youth with Type 1 Diabetes: A Multi-Center Randomized Controlled Trial," will test a brief intervention delivered through mobile health technology intended to optimize family interactions related to diabetes care.

Investigates the relations between cost and reward discounting, microaggressions (diabetes, income, racial), diabetes identity, and youth's perceptions of their health care professional's cultural comfort, humility, and opportunities.

A systematic review of test fairness among psychosocial measures used with youth with diabetes

INQUIRE hopes to explore how the initiation of Closed-Loop Technology influences trajectories of Glycemic Health and Quality of Life among youth with Type 1 Diabetes and their families.

Is developing and testing equitable psychosocial screening and process measures (including computerized adaptive testing) for diabetes clinics.

Interviewing pediatric psychologists living with Type 1 Diabetes about their experiences.

The VITALS project will also explore the youth, caregivers, and healthcare professionals' conceptualization, experiences, and effects of stigma, racism, and discrimination among the T1D community.

 


Past Projects 

The PRYDE study (Predicting Resiliency in Youth with Type 1 DiabEtes) is a collaboration with LeBonheur Children's Hospital Diabetes Clinic. A longitudinal study was conducted from 2013 to 2018 to identify predictors of adherence and glycemic control based on diabetes-specific social information processing and acceptance-based coping models that may reduce health disparities.

Type-1 diabetes (T1D) in childhood is a prevalent and costly disorder associated with substantial morbidity that differentially impacts low-income and minority youth and their families. Given the increased risk for life-threatening consequences of elevated blood glucose and evidence of only modest treatment efficacy in general, the objective of this study was to develop a culturally tailored Acceptance and Commitment Therapy-based behavioral intervention to enhance glycemic health and quality of life in Adolescents with Type-1 diabetes and their families.

The BRAVO intervention was developed within a multicultural orientation (MCO) framework to acknowledge families' diverse sociocultural contexts and clinical needs. This intervention aimed to deliver Focused Acceptance and Commitment Therapy to increase adolescents' and caregivers' health-related psychological flexibility by supporting values-consistent behavior change through openness to internal experiences and present-moment awareness. Initially developed for families seeking bariatric surgery, we hope to expand this intervention to other pediatric populations.
