Joint physical custody, parent-child relationships, and children's psychosomatic problems

Aim The prevalence of psychosomatic complaints among children and adolescents appears to be increasing. At the same time, the numbers of joint physical custody families are rising across Western countries. This study aimed to investigate the relationship between post-separation care arrangements (joint physical custody vs. sole physical custody) and children's risks of psychosomatic problems, while considering the potential mediating role of parent-child relationships. Subject and methods Based on data from the Family Models in Germany (FAMOD) study, stepwise linear regression models and seemingly unrelated regression models were estimated for a sample of 473 children aged seven to 14 living in either sole physical custody or joint physical custody families. Results Children in joint physical custody families reported significantly fewer psychosomatic problems than children in sole physical custody families. Furthermore, living in a joint physical custody arrangement was associated with better parent-child relationships, although only the mother-child relationship was significantly related to children's psychosomatic complaints, and partially mediated the association between physical custody arrangements and children's psychosomatic complaints. No corresponding association could be found with respect to the father-child relationship. Conclusion The risk of psychosomatic problems was distributed unequally among post-separation families, as children living in joint physical custody arrangements suffered from fewer psychosomatic problems than children living in sole physical custody arrangements. Because part of this association was explained by the quality of the mother-child relationship, children's relationships with other family members appear to be important factors to consider when seeking to promote children's health in post-separation care arrangements.
