Final answer:
A Culturagram is the most suitable assessment tool for a social worker to analyze the impact of heritage and belief systems on a family's interactions as it specifically focuses on the influence of culture.
Step-by-step explanation:
Assessing the impact of heritage and belief systems on a family's interactions best aligns with the objectives of a Culturagram. A Culturagram is a tool used in social work to examine the influence of culture on a family's behavior, relationships, and experiences. It incorporates different aspects such as health, education, economics, language, and importantly, cultural heritage and religious beliefs. Genogram maps out relationships and hereditary patterns, and while may exhibit certain cultural factors indirectly, it's primary focus is on familial relations and medical history. A Ecomap focuses primarily on a family's interaction with external systems (social, educational, legal etc.). Person-in-environment is an overarching perspective in social work that proposes a person's behaviors and experiences cannot be separated from their social and physical environments, yet it does not specifically focus on heritage and belief systems.
