BLESSED Research Group

About Us

The Black Early Stages of Social & Emotional Development (BLESSED) Research Group collaborates with Black families with young children living in socioeconomically disadvantaged contexts in DC to gain an understanding of the numerous culturally specific protective factors that families use to support their children’s development. The BLESSED Research Group focuses on culturally sensitive mental health care for Black families. We also have international collaborations to address mental health stigma in Ghana.

Current Projects


Pandemic-Related Projects

Preschooler’s Adjustment to In-Person Learning Following COVID-19-Related School Closures in Black Families: A Mixed Methods Approach.

Within the early childhood education sector, children of color from low-income backgrounds have been the most negatively impacted by the COVID-19 pandemic. There is emerging evidence that Black children experienced larger drops in preschool enrollment, a higher percentage of remote learning, and greater academic setbacks compared to white children during the pandemic—widening racial opportunity gaps and exacerbating parental stress levels. Guided by the integrative model for the study of stress within Black American families, we will conduct a mixed methods, multilevel study with 200 Black families with young children attending early childhood education programs, and their children’s teachers. To obtain a more comprehensive understanding of cultural assets, the study will use a convergent mixed methods approach to assess: (1) children’s adjustment to returning to in-person learning during the 2021-2022 school year and (2) the protective factors that buffer the deleterious impact of parent and teachers’ exposure to racism on preschooler’s social emotional development.

Pandemic-Related Stressors and Mental Health of Black Mothers from Under-Resourced Communities: A Mixed Methods Approach.

The COVID-19 pandemic has disproportionately negatively affected Black mothers, especially those from low-income communities, both personally and professionally. Guided by intersectionality, this project seeks to elucidate how interconnected systems of oppression – racism, sexism, classism – impact Black mother’s mental health, parenting, and parent-child relationships. Using a mixed methods approach, we aim to acquire a unique collective of mothers’ experiences during the COVID-19 pandemic, examine the effects of stressors associated with systemic racism on Black mothers, and determine the influence of protective mechanisms of social support and racial identity. We expect that mothers’ social support and positive racial identity will buffer the harmful effects of pandemic-related stressors on parenting and parent-child relationships transmitted through better maternal mental health. Focus group data will be used to contextualize our findings and identify additional protective factors.


Black Therapy Related Projects

Addressing Attrition And Mental Healthcare Disparities: A Pilot Study of PCIT

The study will provide new insight into the disparate attrition rates of Black families in PCIT and will lead to improved methods for addressing racial disparities in mental health treatment. The project will inform culturally tailored approaches to effectively engage Black families in a well-established evidence-based treatment for families with young children. This work supports the efforts of the Department of Psychiatry’s mission to provide high-quality mental health care and service to the community and translate clinical research into community practice to address the effects of systemic racism on minoritized communities. This research aims to 1) evaluate the acceptability and cultural relevance of typical PCIT assessment instruments and processes with Black families with young children and 2) gather parents’ perceptions of barriers and facilitators of PCIT assessment interviewers.

Understanding the Benefits of Child-Parent Psychotherapy delivered via Telehealth during the COVID-19 Pandemic for Black Families

The COVID-19 pandemic led to a sudden change in families’ environments, limiting access to basic services usually provided through the community, and restrictions for extended family to help with the care of children. For families who isolated away from their support systems, the pandemic may have posed traumatic risks, particularly for African American families who have been disproportionately affected by the pandemic. Child-parent psychotherapy (CPP) was developed as a dyadic, attachment-based, in-person intervention for parents with young children who have experienced trauma related to violence, death, abuse, neglect, caregiver separation, and caregiver substance abuse that promotes secure attachment between the caregiver and child. This case series study evaluates the acceptability of telehealth delivery of child-parent psychotherapy provided to African American families during the COVID-19 pandemic.


Ghanaian Mental Health Projects

Africa’s Mental Health Matters – Ghana Workshop

This project is a collaboration between MedStar Georgetown University Hospital faculty and Africa’s Mental Health Matters (AMHM) – Ghana. We will engage in a collaborative process to (a) conduct semi-structured individual interviews, with 15 Ghanaians experiencing mental health difficulties, to inform the development of a workshop designed to address mental health stigma in Ghana; (b) co-create a grant-seeking plan to sustain our collaboration; and (c) host a workshop in Accra, Ghana designed to de-stigmatize mental health services utilization. We will interview 15 community members experiencing mental illness during Part 1 to inform the structure and specific content of the workshop sessions that participants may find most useful. We will identify and plan grant-writing activities to sustain our work in Part 2. During the workshop (Part 3), Ghanaian psychiatrists, psychologists, researchers, and Safe Circle members will lead sessions focused on normalizing psychological distress and coping with depression, anxiety, trauma, and substance use. A brief knowledge and satisfaction questionnaire will also be administered to participants at the workshop to assess pre/post mental health knowledge, perceptions, beliefs, and stigma, future support group content, and whether the workshop was successful in meeting the participants’ expectations. Results of this work will be used to apply for future funding to support stigma reduction programming in Ghana.

Youth Mental Health Matters: A Community-Based Exploration of Mental Health in Ghana

Youth mental health continues to be a global issue that warrants attention. In Ghana, there’s a level of complexity to the problem, as it has been documented that not only is there a rather large mental health treatment gap among the total population, the “prevalence of mental illness and its burden among adolescents is unknown on a national level.” A combination of the unknown prevalence, treatment gap, and interest in exploring youth mental health in Ghana, led to the development of the proposal. The grant award enables us to bring together Georgetown University faculty and key partners from Accra, Ghana who all have youth mental health expertise, in an effort to begin to develop a community-based, culturally-appropriate exploration of youth mental health needs and assets in Accra, Ghana. This award complements existing work that was recently funded to explore adult mental health issues in Ghana. We will build upon our existing partnership and expand our work to also focus on youth mental health. This will enable a more comprehensive exploration of mental health in Ghana. Our goals are to (a) build a youth-focused community-academic partnership that will guide the exploration; (b) host a seminar designed to explore youth mental health among key community and academic stakeholders; (c) complete community site visits and host a youth-focused community forum that will provide additional knowledge and insight about youth mental health needs and assets; and (d) collaboratively develop a Research and Outreach Plan that will enable the transition of our work from the exploration and planning phase to a research and outreach phase.
