Which term refers to the dynamics of social roles in a family where all members share power equally?

The term that describes a family dynamic where all members share power equally is "egalitarian family." In an egalitarian family structure, decision-making responsibilities, authority, and household duties are distributed among all members without a single person or gender dominating. This approach promotes equality and collaboration within the family unit, allowing for a more balanced and equitable environment.

In contrast, patriarchal families are characterized by a male figure holding primary power and authority, while complementary families generally involve roles that complement each other, but not necessarily with equal power dynamics. Authoritarian families, on the other hand, are characterized by strict control and direction from one or more family members, often limiting participation and shared power among the family members.
