About

William R. Beardslee is the Gardner Monks Professor of Child Psychiatry at Harvard Medical School and serves as the academic chairman of the Department of Psychiatry at Children's Hospital in Boston. He trained in general psychiatry at Massachusetts General Hospital and in child psychiatry and psychiatric research at Children's Hospital. His research focuses on the development of children at risk due to severe parental mental illness, with particular interest in the protective effects of self-understanding in helping individuals cope with adversity. He has studied self-understanding in various populations, including civil-rights workers, cancer survivors, and children of parents with affective disorders. Currently, Beardslee directs the Preventive Intervention Project, an NIMH-funded study exploring a family-based preventive intervention aimed at enhancing resiliency and family understanding for children of parents with affective disorder. He also leads the Boston site of the Prevention of Depression study, evaluating a cognitive behavioral group prevention program developed for children at double risk because they exhibit symptoms of depression and have depressed parents. He serves on multiple advisory boards, including the National Mental Health Association, the Carter Center Task Force on Prevention, and the prevention committee of the American Psychiatric Association. Beardslee is the author of over 100 articles and chapters, as well as two books: 'The Way Out Must Lead In: Life Histories in the Civil Rights Movement' and 'Out of the Darkened Room: Protecting the Children and Strengthening the Family When a Parent Is Depressed.'

  Abstract This chapter examines the prevention of major depressive disorder (MDD), highlighting its global impact, particularly on adolescents. It traces the historical development of mental health prevention, exploring the evolution of classification systems and intervention strategies. The chapter outlines prevention methods, including universal, selective, and indicated approaches, focusing on family-based, school-based, and technology-driven programs. It emphasizes key risk factors such as subthreshold depression, adverse childhood experiences, and cultural influences, stressing the importance of early intervention. Finally, the chapter advocates for continued research to enhance prevention strategies, noting that targeted interventions for at-risk populations, especially adolescents, are essential to addressing the growing burden of depression.

• Delivering a family‐based child mental health promotion program among two resettled refugee communities during the COVID‐19 pandemic: Lessons learned in a hybrid type II implementation‐effectiveness randomized controlled trial

  American Journal of Community Psychology · 2025-10-05

  articleOpen access

  BACKGROUND: Resettled refugee families face elevated mental health risks, compounded by structural and cultural barriers. The Family Strengthening Intervention for Resettlement (FSIR), co-developed with resettled refugee communities, aims to improve family functioning and child mental health. This study evaluated FSI-R in Somali Bantu and Bhutanese communities in New England during COVID-19 using a Hybrid Type II Implementation-Effectiveness Trial guided by the EPIS framework. METHODS: Linear mixed modeling assessed changes in family functioning and child mental health. A process evaluation identified implementation barriers and informed adaptations. Activities were registered under Clinical Registry #NCT03796065. RESULTS: Bhutanese families receiving FSI-R showed greater improvements in parental supervision compared to usual care. Process evaluation highlighted that responsiveness to community needs supported successful implementation despite pandemic stressors. Somali Bantu interventionists reported stronger emotional connection with families during in-person delivery. CONCLUSIONS: Findings support the utility of hybrid trials in assessing both effectiveness and implementation of preventive interventions with resettling families. Despite contextual disruptions, attention to community needs and delivery flexibility enabled successful implementation. This study underscores the importance of context-informed strategies to sustain core elements of evidence-based interventions in dynamic settings.

  , it is appropriate to reflect on the evolution of thought on depression prevention research, as seen through a historical perspective, to note how the field has grown and how it can address the issues of today. This article is a personal reflection on one practitioner's evolution of thought on resilience and preventive intervention, starting with interviewing civil rights workers, to conceptualizing self-understanding as an essential component of resilience, to the development of a family-based preventive intervention for parental depression, which was disseminated, adapted, and incorporated into a growing body of prevention research. Consensus statements on mental health prevention from the National Academies are reviewed, and the importance of a social justice perspective is highlighted throughout. The article concludes with principles for developing effective preventive interventions to promote mental health today, and in the future.

• Cognitive behavioral program for the prevention of depression in at-risk adolescents: isolating the effects of dose

  American Journal of Epidemiology · 2024-06-18 · 3 citations

  articleOpen access

  The current study estimated effects of intervention dose (attendance) of a cognitive behavioral prevention (CBP) program on depression-free days (DFDs) in adolescent offspring of parents with a history of depression. As part of secondary analyses of a multisite randomized controlled trial, we analyzed the complete intention-to-treat sample of 316 at-risk adolescents ages 13 to 17 years. Youth were randomly assigned to the CBP program plus usual care (n = 159) or to usual care alone (n = 157). The CBP program involved 8 weekly acute sessions and 6 monthly continuation sessions. Results showed that higher CBP program dose predicted more DFDs, with a key threshold of approximately 75% of a full dose in analyses employing instrumental variable methodology to control multiple channels of bias. Specifically, attending at more than 75% of acute phase sessions led to 45.3 more DFDs over the 9-month period after randomization, which accounted for over 12% of the total follow-up days. Instrument sets were informed by study variables and external data, including weather and travel burden. In contrast, conventional analysis methods failed to find a significant dose-outcome relation. Application of the instrumental variable approach, which better controls the influence of confounding, demonstrated that higher CBP program dose resulted in more DFDs. This article is part of a Special Collection on Mental Health.

• Adaptation of an evidence-based, preventive intervention to promote mental health in Hispanic adolescents: <i>eHealth Familias Unidas Mental Health</i>

  Translational Behavioral Medicine · 2024-10-26 · 2 citations

  articleOpen access

  Youth internalizing symptoms (i.e., depression and anxiety), suicide ideation and attempts have been rising in recent years, including among Hispanics. Disparities in mental healthcare are concerning and require intervention, ideally prevention or early intervention. Familias Unidas is a culturally-syntonic, family-centered intervention effective in reducing youth drug use and sexual risk, with evidence of unanticipated effects on internalizing symptoms. This paper describes the systematic process used to adapt the eHealth version of the Familias Unidas intervention to more directly address internalizing symptoms and suicide risk in preparation for an effectiveness-implementation hybrid trial for youth with elevated internalizing symptoms, a history of suicide ideation/attempts, or poor parent-youth communication. The resulting eHealth Familias Unidas Mental Health intervention is described. Guided by a 4-phase framework, the steps in the adaptation process involved: assessment of the community and intervention delivery setting (pediatric primary care clinics); integration of previous intervention research, including intervention mechanisms of action; and expert and community consultation via focus groups. Focus group analyses showed that youth and parents perceived that the intervention was helpful. Their feedback was categorized into themes that were used to directly target mental health by addressing technology use, parent mental health, and social support. Effective and scalable preventive interventions are needed to address mental health disparities. The systematic adaptation process described in this paper is an efficient approach to expanding interventions while maintaining known, empirical and theoretical mechanisms of action. Findings from the ongoing effectiveness-implementation trial will be critical.
