What is the for the drama? (A death, a wedding, a financial crisis?) Family Dynamics - StatPearls - NCBI Bookshelf - NIH
To build a realistic family dynamic, focus on the patterns of interaction and the roles relatives play within the group.
Remember that "true family" is not always biological. Ties can be broken, and new, chosen families can be formed.
Dynamics often fall into categories like authoritative (healthiest), authoritarian (rigid), or competitive (high tension).
