Final answer:
Population-focused practice in community psychology focuses on 'c. communities', aiming to implement solutions that are culturally responsive and promote equity.
Step-by-step explanation:
Population-focused practice specifically addresses the needs and solutions for either individuals, aggregates, communities, or geographical regions. In the field of community psychology, the focus is often on larger groups rather than just individuals, because social problems are typically best understood within broader contexts, such as social, cultural, economic, geographic, and historical spheres. Community psychologists aim to implement initiatives, interventions, or prevention strategies that are culturally responsive and promote equity within these groups.
Community psychology practice involves collaboration with various professionals in the social service sector to address the complex dynamics within a community that affect individuals and families. This multidisciplinary approach leads to more effective solutions and positive outcomes in the practice of community psychology. The correct answer regarding whom population-focused practice is directed at is 'c. communities', as community psychologists work to understand and address issues at a community-wide level.
