Out-of-home care and parental death are both associated with psychiatric disorders. It remains unclear whether parental death moderates the association between out-of-home care and psychiatric disorders, particularly regarding timing and duration of out-of-home placement. This cohort study included 944,138 individuals (459,712 women and 484,426 men) born in Sweden (1972–1981). Of these, 23,106 individuals (2.5%) experienced out-of-home care between ages 0 and 19. Psychiatric disorders, identified from the National Patient Register, were examined as the outcome. Information on parental death between ages 0 and 19 years and familial covariates was obtained from linked national registers. Sex-stratified Cox proportional hazard models examined the associations between out-of-home care, parental death, and psychiatric disorders from ages 20 to 47 years. Individuals with experience of out-of-home care had increased psychiatric risk across adulthood, with the highest risks observed for teenage placements. Parental death was also associated with an increased psychiatric risk. Associations between parental death and psychiatric disorders were attenuated across the teenage, long-term, and early intermediate placement groups among women and across the early intermediate, teenage, and early short-term placement groups among men compared with non-placed counterparts. Findings suggest that parental death adds limited risk within a highly vulnerable and disadvantaged population, highlighting the importance of interventions addressing multiple risks across developmental periods.
