Living arrangements after parental separation have minimal impact on mental health at age 7 years

Systematic review and theoretical comparison of children's outcomes in post-separation living arrangements

The purpose of the systematic review was to synthesize the literature on children's outcomes across different living arrangements (nuclear families, shared physical custody [SPC], lone physical custody [LPC]) by extracting and structuring relevant theoretical hypotheses (selection, instability, fewer resources, and stressful mobility) and comparing the empirical findings against these hypotheses. Following the PRISMA guidelines, the review included 39 studies conducted between January 2010-December 2022 and compared the living arrangements across five domains of children's outcomes: emotional, behavioral, relational, physical, and educational. The results showed that children's outcomes were the best in nuclear families but in 75% of the studies children in SPC arrangements had equal outcomes. Children in LPC tended to report the worst outcomes. When compared with the different theoretical hypotheses, the results were the most consistent with fewer resources hypothesis which suggests that children especially in LPC families have fewer relational and economic resources whereas children in SPC families are better able to maintain resources from both parents.

Coparenting as a mediator between physical custody arrangements and children's mental health

The detrimental effects of parental break-up on children's mental health are well-documented. However, research has also shown that children living in joint physical custody (JPC) arrangements often fare better than children living in sole physical custody (SPC) arrangements. Thus, the question arises: What are the differences between JPC and SPC that account for those results? Drawing on data from the Family Models in Germany (FAMOD) study conducted in 2019, structural equation models (SEM) were estimated to deduct the mediating role of coparenting support in children's mental health in 465 JPC and 652 SPC families with children aged 2-14. The findings suggest that the better mental health observed among children in JPC families than among children in SPC families was fully mediated by coparenting support. However, this held true only for internalizing and externalizing behavior, but not for prosocial behavior as no differences between JPC and SPC were found for this dimension. The findings affirm the importance of supportive coparenting for children's well-being after family dissolution in both SPC and JPC arrangements. After breaking up, parents should be supported in their parental engagement through coparenting counseling or psychoeducation classes.

Post-Separation Physical Custody Arrangements in Germany: Examining Sociodemographic Correlates, Parental Coparenting, and Child Adjustment

Most children continue to live with their mother after a divorce or separation, yet paternal involvement in post-separation families has increased substantially in many Western nations. This shift has contributed to a growing share and more diverse set of post-separation parents opting for shared physical custody (SPC), which typically means that children alternate between the parental residences for substantive amounts of time. Profiling the case of Germany, where no legal regulations facilitating SPC are implemented to date, we examine the prevalence of SPC families, sociodemographic correlates of SPC, and its associations with parental coparenting and child adjustment. Using representative survey data sampled in 2019 (N = 800 minors of 509 separated parents), results revealed that only 6–8% of children practiced SPC. SPC parents were more likely to hold tertiary levels of schooling and to report a better coparenting relationship with the other parent. There was no link between SPC and child adjustment, yet conflictual coparenting was linked to higher levels of hyperactivity among SPC children. We conclude that the social selection into SPC and linkages between conflictual coparenting and hyperactivity among SPC children likely stem from the higher costs and the constant level of communication between the ex-partners that SPC requires.

Mental Health in Schoolchildren in Joint Physical Custody: A Longitudinal Study

This study investigated mental health in schoolchildren in different living arrangements after parental separation. The study population included 31,519 children from the Danish National Birth Cohort, followed-up at age 11 in 2010–2014. Child mental health was measured with a maternal report of the Strength and Difficulties Questionnaire (SDQ). Associations between living arrangements and mental health were analyzed using logistic and linear regression models, taking into account early childhood indicators of the parents’ relations, income, education and psychiatric care. At age 11, children living in a nuclear family had the lowest rate of total SDQ score, 8.9%. Of the children who had experienced parental separation, children in joint physical custody had the lowest adjusted odds ratio (OR)1.25 (95%-CI 1.09–1.44), for a high SDQ score relative to children living in a nuclear family, with adjusted ORs of 1.63 (1.42–1.86) and OR 1.72 (1.52–1.95) for sole physical custody arrangements with and without a new partner. An analysis of change in SDQ scores between ages 7 and 11 in children showed a similar pattern. This study indicates that joint physical custody is associated with slightly more favorable mental health in schoolchildren after parental separation than sole physical custody arrangements.
