According to Bowen, a family is a system in which each member has a role to play and rules to respect. Although the specific roles that each person plays depend on the culture of the people, in most communities men generally play instrumental roles while women play expressive roles. Children on their part assist the parents in different roles and tasks as may be assigned. Further, members of the system are expected to respond to each other in a certain way according to their role. In this respect, parents are supposed to be close, warm and supportive to each other, and loving, patient, sensitive and responsive to their children. In addition, authoritative parenting is more preferred to other parenting styles because it results in children who have desirable characteristics. Similarly, children should respond positively to their parents by being warm, responsive and obedient. Indeed responsible and level-headed children enable parents to be more loving and reasonable in setting rules, while rude, hostile and aggressive children make parents hostile in return.
