Abstract
International adoptees need to cope with stressful transitions and to develop secure attachment with their caregivers at the same time. Although most children adopted from abroad adjust fine, they are at increased risk of psychological problems. We investigated whether both child and family-related factors are associated with later psychological problems and whether the length of time spent at home after adoption before daycare moderates these associations among internationally adopted children in Finland (FinAdo, Finnish Adoption Study). The sample consisted of 1,265 children (708 girls, 557 boys) who arrived in Finland before they started school (mean age 2 years at arrival). Later behavioral problems were measured using the Child Behavior Check List (CBCL). According to our results, male gender, older age, child's early clinical symptoms (problems of sensory processing) and single parenthood were associated with later behavioral problems measured by CBCL scores. Longer stay at home before the start of daycare or school modified these results. Longer stay at home was associated with less later behavioral externalizing problems in girls but not in boys compared to those who spent a shorter time at home.
