Ethnic families do not fit this model because they adapt and bond by different processes. the way in which a family changes its relationship rules, power structure, and role expectancies in response to either normal developmental changes or crises relates to its

Adaptability.

Explanation:

Theorists use a Circumplex Model to conceptualize clustering of different theoretical concepts from family theory and other social sciences - sociology, psychiatry, etc. This clustering revealed two central dimensions of the way people behave in family systems: Cohesion and Adaptability.

1. Family Cohesion:

is defined as emotional bonding of family members. It includes bonding, boundaries, time, space, decision making, friends, etc.

2. Family Adaptability:

is defined as the way in which a family power structure, roles, rules when they need to respond to situational and developmental stress. In this dimension the concepts of assertiveness, control and discipline, negotiation styles are included.

well this isn't a question but if you are asking if it is true or false it is, true.
