First evaluation of Eyberg Child Behavior Inventory for foster children in Japan.

Abstract

Behavioral problems of foster children are an important issue for the maintenance of the foster care system, but they have not been adequately studied in Japan. We used the Eyberg Child Behavior Inventory (ECBI) to investigate behavioral problems among foster children and to examine associated factors. Twenty-nine foster children and their foster parents and 479 non-foster children and parents were recruited for the foster and control groups, respectively. Both groups underwent statistical comparative analyses using data from their ECBI assessments. The ECBI has two scales: the Intensity Scale quantifies the severity of child behavioral problems, and the Problem Scale captures the caregiver's perceived difficulties handling each behavior. We conducted a retrospective investigation of the background of the foster parent-child pairs to explore potential causal relationships with behavioral problems. The mean intensity score for the foster group was significantly higher than that for the control group (p = 0.001). The mean problem scores for the foster group and the control group were not significantly different (p = 0.79). In the foster group, the retrospective investigation revealed two children with neurological or neurodevelopmental disorders, 17 with histories of abuse, and 10 with other issues. Intensity scores showed severe behavioral problems among foster children, perhaps caused by neurological disorders, abuse, parental mental health, or economic hardship. Problem scores showed no significant differences between groups. It can therefore be posited that foster parents might exhibit a more lenient parenting style when dealing with children who have a history of abuse by their biological parents.
