Hi!

This would fit more in the psychology field rather than social studies, but the answer to your question is the defeated.

Explanation:

According to Hetherington's studies, there's a group of individuals amongst the population characterized by a "defeated" attitude, hence the name "the defeated". Based on Hetherington's studies, some of these individuals had problems before their divorce and these problems worsened after their failed marriage because the stress was more than they could handle. Most of the people in this group had difficulty coping because divorce cost them a spouse who had supported them.
