published in Journal of Marriage and Family found that when cohabitation was uncommon in pre-reform China, premarital cohabitation increased the likelihood of subsequent divorce, but this association disappeared when cohabitation became prevalent. Effects Some of the effects associated with divorce include academic, behavioral, and psychological problems. Although this may not always be true, studies suggest that children from divorced families are more likely to exhibit such behavioral issues than non-divorced families. Divorce and relationships Research done at Northern Illinois University on Family and Child Studies suggests that divorce of couples experiencing high conflict can positively affect families by reducing conflict in the home. There are, however, many instances when the parent-child relationship may suffer due to divorce. Financial support is many times lost when an adult goes through a divorce. The adult may be obligated to obtain additional work to maintain financial stability. This can lead to a negative relationship between the parent and child; the relationship may suffer due to a lack of attention towards the child and minimal parental supervision Studies have also shown that parental skills decrease after a divorce occurs; however, this effect is only a temporary change. "Many researchers have shown that a disequilibrium, including diminished parenting skills, occurs in the year following the divorce but that by two years after the divorce re-stabilization has occurred and parenting skills have improved." Some couples choose divorce even when one spouse's desire to remain married is greater than the other spouse's desire to obtain a divorce. In economics, this is known as the Zelder Paradox and is more familiar with marriages that have produced children and less common with childless couples. Research has also found that recent divorcees report significantly higher hostility levels after the divorce than before, and that this effect applies equally to both male and female divorcees. In an American Psychological Association study of parents' relocation after a divorce, researchers found that a move has a long-term effect on children. In the first study conducted amongst 2,000 college students on the effects of parental relocation relating to their children's well-being after divorce, researchers found major differences. In divorced families in which one parent moved, the students received less financial support from their parents compared with divorced families in which neither parent moved. These findings also imply other negative outcomes for these students, such as more distress related to the divorce and did not feel
