Custody arrangements were defined as mother custody, father custody and shared custody. Also in the United States, Donnelly and Finkelhor used a national sample to explore the extent to which shared custody had an impact on child-to-parent support and affection, parent-to-child support and affection, and parent-child disagreements.
From the perspective of the children, compared to those in a sole custody arrangement, adolescents in a shared custody arrangement were more likely to report that they felt close to both parents Buchanan et al.
Most JPC parents do not mutually or voluntarily agree to the plan at the outset. Data on the relationship between the parents with shared versus other types of custody arrangements are difficult to interpret because shared custody parents are a self-selected group—they are probably better able to co-operate than are many other parents.
Also, approximately one quarter of the parents with shared custody expressed concern about their children's lives in the home of the other parent, including parenting style and lifestyle Maccoby and Mnookin, In shared custody situations, most parents believed that their former partners had a good relationship with the children, and adolescents in shared custody were more likely to report that they felt close to both parents.
The findings are conflicting and more than a little confusing. Some studies have found that non-custodial mothers are more involved in child rearing than are non-custodial fathers. Girls showed better adjustment in shared rather than sole custody arrangements, whereas boys did better in sole custody Hendrickson, The available evidence indicates that the type of custody arrangement the parents choose is not strongly related to the inter-parental relationship.
The authors also point out that the re-litigating joint legal custody parents were not necessarily dissatisfied with their arrangement, since most joint families who altered their arrangements kept their joint legal status, changing only the physical placement of the children Koel et al.
In fact, however, the study is not in any way applicable to the general population.
