Our Projects

Some of Our Current Research Areas:

  • Factors associated with successful transition from child psychiatry to adult psychiatry for transition age youth (18 to 20)

  • Experiences of individuals following a hospitalization for first episode psychosis, and predictors of subsequent successful engagement in care

  • Understanding and unpacking indicators of suicidal behavior among youth who have been hospitalized for a mental health condition.

  • Improving treatment for children who have comorbid obesity and behavioral health conditions through an integrated intervention delivered in primary care.

  • A Scoping Review of the Intersectionality of Autism and Intellectual and Developmental Disability with Social Inequity on Diagnosis and Treatment of Youth

    Weiss, M.D., Daniolos, P.T., Coughlin, K., Mulvaney-Day, N., Cook, B., & Rosenblum, D. (2024). 

    Objective: To describe how the intersectionality of race, ethnicity, and language with autism and intellectual and developmental disability (IDD) impacts mental health inequities in psychopharmacological management of youth. Method: This was a scoping review in which a series of searches were conducted in PubMed, Web of Science, Google Scholar, and manual review of the articles collected. Results: Although autism and/or IDD increases the risk for poor physical and mental health, social determinants of health such as race, ethnicity, and language account for approximately a third of poor outcomes. Minoritized children with autism/IDD experience significantly greater delays to diagnosis and misdiagnosis and are less likely to receive appropriate services. Access to psychological testing and psychosocial services is often limited by availability, skilled practitioners, a shortage of non-English-language providers or interpreters, and poor reimbursement. Conclusion: The intersectionality of autism and/or IDD with race, ethnicity, and language compounds the health inequities associated with either of these challenges independently.

  • Association between electronic nicotine product use and subsequent first episode psychosis

    Hyatt, A.S., Mulvaney-Day, N., Chow, C.M., Cook, B.L., & Delisi, L.E. (2024). 

    Tobacco use has been established as a possible risk factor for psychosis, but the effect of electronic nicotine delivery systems (ex. nicotine vapes) has not been independently established. Using the Population Assessment of Tobacco and Health study, we found that use of electronic nicotine products was significantly associated with later first episode psychosis after controlling for substance use and other confounders, and that this relationship was only significant among the heaviest users (>20 puffs/day). Given the rapid rise in electronic nicotine products use, clinicians and public health professionals should consider potential impacts and closely monitor trends in the coming years.

  • The Impact of School Closures on Service Utilization in School-Based Health Center

    Richards, E.C., Allen, M.R., & Weiss, M.D. (2023).

    Background: The pandemic was followed by a severe mental health crisis in youth with both an increase in the prevalence of mental health problems and a decrease in requests for and access to care. Methods: data were extracted from the school-based health center records in three large public high schools that include under-resourced and immigrant communities. Data from 2018/2019 (pre-pandemic), 2020 during the pandemic, and then in 2021 after the return to in-person school were compared regarding the impact of in-person, telehealth, and hybrid care. Results: Despite the increase in mental health needs globally, there was a dramatic decrease in referrals, evaluations, and the total number of students seen for behavioral health care. The time course of this decrease in care was specifically associated with the transition to telehealth, although treatment did not return to pre-pandemic levels, even after in-person care became available. Conclusions: Despite ease of access and increased need, these data suggest that telehealth has unique limitations when delivered in school-based health centers.

  • What happens after early intervention in first-episode psychosis? Limitations of existing service models and an agenda for the future.

    Hyatt, A. S., Hasler, V., & Wilner, E. K. (2022).

    Early intervention in first-episode psychosis (FEP) improves symptomatic and functional outcomes while programs last. However, these gains may not be sustained over time and not all individuals benefit equally from such programs. This review examines the efficacy of FEP programs, as well as step-down practices and long-term outcomes to identify ways to extend the gains made in FEP programs.

  • Remote Care Management for Older Adult Populations With Elevated Prevalence of Depression or Anxiety and Comorbid Chronic Medical Illness: A Systematic Review.

    Lim, C. T., Rosenfeld, L. C., Nissen, N. J., Wang, P. S., Patel, N. C., Powers, B. W., & Huang, H. (2022). 

    A systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A multidatabase search was performed. Articles were included for review if they studied fully remote care management for older adult populations with elevated prevalence of depression or anxiety and chronic medical illness or poor physical health. A narrative synthesis was performed.

  • Toward Population Health: Using a Learning Behavioral Health System and Measurement-Based Care to Improve Access, Care, Outcomes, and Disparities.

    Tepper, M. C., Ward, M. C., Aldis, R., Lanca, M., Wang, P.S., Fulwiler, C.E. (2022).

    Achieving population behavioral health is urgently needed. The mental health system struggles with enormous challenges of providing access to mental health services, improving quality and equitability of care, and ensuring good health outcomes across subpopulations. Little data exists about increasing access within highly constrained resources, staging/sequencing treatment along care pathways, or personalizing treatments. The conceptual model of the learning healthcare system offers a potential paradigm shift for addressing these challenges. In this article we present an overview of how the three constructs of population health, learning health systems, and measurement-based care are inter-related, and we provide an example of how one academic, community-based, safety net health system is approaching integrating these paradigms into its service delivery system. Implementation outcomes will be described in a subsequent publication. We close by discussing how ultimately, to meaningfully improve population behavioral health, a learning healthcare system could expand into a learning health community in order to target critical points of prevention and intervention.

  • Promoting Population Behavioral Health in a Safety-Net Health System During the COVID-19 Pandemic

    Lim, C. T., Fulwiler, C. E., Carson, N. E., Huang, H., Robinson, L. A., Schuman-Olivier, Z., O'Brien, C.J., Wang, P. S. & Tepper, M. C. (2021). 

    The COVID-19 pandemic has been expected to lead to substantial increases in need for behavioral health care. A population health framework can facilitate the development of interventions and policies to promote the equitable distribution of care across the population. This column describes the application of population behavioral health principles in a safety-net health system during the pandemic. The approach includes stepped models of care, interventions to target individuals at high behavioral health risk, and measurement-based care. Early data suggest that these strategies have resulted in expanded behavioral health care capacity.
