Members of marginalized groups face numerous stressors, including racism, discrimination, and a lack of access to quality mental health and medical care. Members of marginalized groups are also at a higher risk of developing mental health issues such as posttraumatic stress disorder, depression, and anxiety. There is a lack of literature regarding effective mental health treatment for members of marginalized groups, including those who are homeless or low income; Black, indigenous, and people of color (BIPOC); and women. A literature review indicated interventions based in empowerment, positive psychology, mindfulness, and critical consciousness may be particularly applicable to vulnerable populations. Therefore, the purpose of this project was to develop a group intervention and facilitator manual intended for use with marginalized groups to facilitate empowerment and increase well-being. The development of the manual included a review of existing literature and interventions for marginalized groups with a focus on empowering interventions. The primary aim of the intervention is to improve the empowerment and well-being of participants. Seven licensed mental health professionals evaluated the group intervention manual and their feedback was analyzed for themes and suggestions. Strengths and weakness regarding the intervention and format of the manual are discussed and the contributions and limitations of this research project are reviewed. Recommendations are provided for modifications and future development of the intervention.
