Severe punishment of children by staff in Romanian placement centers for school-aged children: Effects of child and institutional characteristics

The objective of this study was to determine whether children's characteristics and/or institutional characteristics were predictors of severe punishments (including beatings) and/or frequency of punishments that children received from staff in Romanian institutions. The data was hierarchical with institutionalized children (N = 1391) nested within 44 institutions, and the measurement of punishments by the staff and frequency of punishments had a binary distribution. Thus, multilevel logistic regression models were used to examine the effects of individual and institutional level variables on reported punishments and to account for the clustering of the children within institutions. Two general patterns of results emerged. First, regarding individual level variables, it was found that: (1) amount of time spent by children in their current institutions had a significant effect on the probability of being punished by staff and the frequency of this punishment; (2) the probability of being punished was higher for boys than for girls; and (3) having no siblings in the institution increased the odds of being punished several times. Second, regarding institutional level variables: (4) being in placement centers for school-aged children with a traditional type of institutional organization increased the odds of severe punishment compared to a familial/mixed type. The results of the present study highlight the importance of understanding the consequences of institutionalization in a broader way, where children not only experienced early severe psychosocial deprivation as documented in other studies, but also high levels of severe punishments administered by institutional staff.

Lexical ambiguity: making a case against spread

We argue for decreasing the use of the word spread when describing the statistical idea of dispersion or variability in introductory statistics courses. In addition, we argue for increasing the use of the word variability as a replacement for spread.     

Children with behavioral, non-behavioral, and multiple disabilities, and the risk of out-of-home placement disruption

Objective

This study examined the relative risk of placement disruption for 3-10 year-old children placed in out-of-home care based on the biological relatedness of the placement caregiver and child disability status: no disability, a non-behavioral disability only, a behavioral disability only, or both a non-behavioral and behavioral disability.

Methods

Data were used from the baseline and 36 month follow-up of the National Survey of Child and Adolescent Well-Being, a national probability study of children investigated for child abuse and neglect in the United States. Disability status was derived using several different nationally-normed measures of language development, daily-living skills, social skills, and behavioral problems.

Results

Around 1 in 4 children placed in out-of-home care experienced a disruption. Placement with kin decreased the likelihood of disruption for a majority of children, and children with different types of disabilities were no more or less likely to disrupt in kinship care compared to children with no disability. Older children with a behavioral disability only or both a non-behavioral and behavioral disability were more likely to disrupt compared to younger regardless of placement.

Conclusion

The study findings suggest that maltreated children placed with kin will be afforded the same stability provided to children without a disability.     

Foster care assessment: A study of the placement decision process in Flanders

Family foster care placement decision-making has a weak scientific underpinning. Mostly a ‘variable-oriented approach’ is taken, which requires a lot of information that is not always available. The identification of clusters of foster children with similar characteristics may be a more viable decision strategy. In this study we investigated if foster children could indeed be clustered, which problems were identified at the time of placement, and the influence of placement history. It proved possible to group foster children into two clusters: (1) young children with familial problems and few behavioral problems, and (2) older children with prominent child problems and behavioral problems. For foster children with and without placement history, problems associated with placement proved identical. Considering that a foster care placement did not result in fundamental change in the problems present at time of placement, the importance is stressed of approaching foster care assessment as part of a decision making process which looks back as well as forward. Placement decisions should be based on an appraisal of the appropriateness of foster placement as a solution for the child. In conjunction with this appraisal a decision is required on how parents can be supported toward reunification. Or – if this is not an option – whether long term foster care is the best option for the child and if so, what conditions need to be met.

Age-specific risk factors associated with placement instability among foster children

Placement instability places foster children at an increased risk of negative developmental outcomes. Previous research has yielded inconsistent results on risk factors for placement instability. Therefore, we investigated two research questions: (1) Which child attributes and case histories are associated with placement disruptions (moves indicative of child, agency or caregiver dissatisfaction with the existing placement)?; and (2) How do associations of child attributes and case histories with placement disruptions vary by developmental stage --early childhood (0–5 years), middle childhood (6–12 years), and adolescence (13 years or older)? Using a complete entry cohort of 23,765 foster children in Texas, our results demonstrated that the effects of different risk factors varied by placement end reason and across developmental stages. Of note, kinship placement, compared to non-relative foster care, and placement with all siblings were each associated with an increased risk of substandard care disruptions. Placements with females or Hispanic children were at an increased risk of child-initiated disruption, whereas placements with Black children were more likely to end due to placement mismatch or substandard care reasons. Finally, the adolescence age group was always associated with the greatest increase in risk regardless of disruption reason. These findings provide researchers, caseworkers, and policymakers important information on the risk factors for placement instability among children in foster care.
