Final answer:
The therapeutic approach most focused on prevention is the community psychology approach which aims to understand and improve community dynamics and prevent issues at a systemic level.
Step-by-step explanation:
The therapeutic approach that most stresses prevention is the community psychology approach. Community psychology focuses on identifying and understanding the dynamics of a community and developing interventions and prevention strategies to meet community challenges. They prioritize the eradication of systemic oppression and inequity that impacts individuals, families, and communities. Community psychologists work in a variety of settings, including academia, research institutions, governmental organizations, and as community practitioners.
Their goal is to create and promote environments with equitable resources and to prevent problems before they start, which contrasts with other approaches that might focus more on individual treatment.
