spending time in foster homes or institutions. Program development to reduce the burden of childhood maltreatment may therefore benefit from considering the negative effects of maltreatments across a broad range of childhood environments. Further, despite moderate tetrachoric correlations between maltreatments (range 0.38–0.82, mean 0.55, median 0.53), four of the five maltreatments remained significant after controlling for co-occurring maltreatments. This suggests that the interrelationships between childhood maltreatments may be especially important in understanding the risk of developing future psychiatric disorders, and could be considered in future work.
