The family can be looked at many ways but there are only four theories through which it is looked upon.
System Theory - focuses on the social aspect of the family and its interdependent members who maintain order.
Exchange Theory - views the family's interactions as a cost-benefit analysis wherein the members try to keep their individual costs lower than that of their rewards.
Symbolic Interaction Theory - everything that someone does can be interpreted differently by each and every member of the family. Each member of the family is different and has been shaped and influenced slightly differently then the other members and so sees every action in a different set of eyes.
Conflict Theory - it is known that all people are different and not all people agree upon all topics. this theory focuses on the observance that in contradictory interests and inequalities, the families result in conflict and change.
