the pattern =?

"This is not the pattern if the 1 Equifinality is a concept central to family systems theory" = "This is not the pattern that belongs to that of family systems theory if the 1 Equifinality is a concept central to family systems theory?"

Context:

Family decision making is frequently described as a phased problem solving loop beginning with phase 1 (identifying the problem, formulating a goal, and assessing resources), phase 2 (generating and assessing alternatives), phase 3 (selecting the best option) and phase 4 (accepting a decision, putting it into effect, and evaluating the outcome) [10]. Such a model assumes decisions are made over a period of time and conclusions may be reached
before the family assimilates the change and moves on. This is not the pattern if the 1 Equifinality is a concept central to family systems theory. It supposes that there is more than one route or option that can lead to the same final outcome.
