Final answer:
In a dysfunctional family system, the spouse often assumes the role of the Primary Enabler, a dynamic that can be understood through the lens of functionalism and symbolic interactionism.
Step-by-step explanation:
In a dysfunctional family system, the traditional role which the spouse plays is referred to as the Primary Enabler. This role is often seen in families where one member has an addiction or behavioral issues, and the primary enabler may unconsciously contribute to the maintenance of these issues by preventing the family member from facing the consequences of their actions. This is to keep the family system in a status quo, even if it's dysfunctional. Role dynamics in a family, particularly dysfunctional ones, illustrate the complex nature of family systems and interactions. Sociological perspectives like functionalism and symbolic interactionism help to explain the social construction of family roles and how they contribute to the stability or instability of society.
