Systemic Family Development Theory
Diana Lang
The Systemic Family Development Theory asserts that families are (a) complex, (b) extremely diverse related to the types, numbers, and timing of transitions and stressors, and (c) multigenerational systems. It also assumes that

families share common processes through their development, but the processes must take into account intergenerational influences and variations within and between all families. No two families are alike.[1]
Many studies have shown that patterns of family interactions are similar within families across generations.[2] [3] Intergenerational transmissions of conflict, trauma, communication styles, parenting practices, etc., continue to be examined.
The following genogram (a pictorial display of family relationships and medical history) shows relationship patterns across generations within a family.
