Joint physical custody (equally much with both parents) serves as the reference category.
Model 1 is adjusted for age and country of origin, model 2 is adjusted as model 1 and for the child's perception of own material resources. Model 3 is adjusted as model 1 and for the child's satisfaction with parents–child relations. Model 4 is adjusted for all the previous variables. Clustering by school is accounted for by using a two-level random intercept model.
