Which approach is defined as the therapist managing familial interactions to encourage health?

The correct approach that involves the therapist managing familial interactions to encourage health is boundary marking. This concept refers to the establishment of clear limits and guidelines within family systems that help individuals understand their roles, responsibilities, and the appropriate ways to interact with one another. By marking boundaries, therapists encourage healthier communication patterns and relationship dynamics among family members. This process can involve guiding family members in discussing their feelings, needs, and expectations in a way that fosters respect and understanding.

Boundary marking is essential in family therapy as it helps to prevent enmeshment (excessive emotional closeness) and fosters a sense of individuality among family members. This strengthens the overall health of the family system by allowing each member to function effectively both as a part of the unit and as an individual.

Considering the other choices: the directive approach emphasizes active involvement by the therapist in guiding the session, rather than managing interactions in a familial context. Relaxation techniques are focused on individual stress management and do not directly pertain to managing family interactions. The enactable method refers to interventions that are implemented during therapy but does not specifically address the management of family interactions aimed at promoting health.
