Type of Study: Randomized controlled trial
Number of Participants: 72 foster families

Population:

• Age — Children: 4–7 years; Adults: Approximately 40 years
• Race/Ethnicity — Children: 86% Caucasian, 6% African American, and 4% Hispanic; Adults: Not specified
• Gender — Children: 61% Female and 39% Male; Adults: Not specified
• Status — Participants were foster and kinship parents and their children.

Location/Institution: Oregon counties

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to measure the impact on children of a $70-per-month supplement to foster parent's normal reimbursements and of increased training and support of the foster parents through a training and support program [now called KEEP]. The effects on foster parent dropout rates were also evaluated. Participants were randomly assigned to KEEP (intervention) or one of two control conditions. Measure utilized include the Parent Daily Report. Results indicate that intervention parents reported lower rates of child problem behaviors, had fewer placement disruptions, and fewer foster parents dropped out of providing care. Limitations include small sample size, reliability on self-reported measure, and lack of follow-up.

Length of controlled postintervention follow-up: Not specified.

Location/Institution: San Diego, California

Summary: (To include basic study design, measures, results, and notable limitations)
The study used the same sample as Price et al. (2008). The purpose of the study was to test the effectiveness of KEEP (Keeping Foster Parents Trained and Supported) [now called KEEP] with 700 foster/kinship parents in San Diego County. Participants were randomly assigned to KEEP or control (usual caseworker services) condition. Measures utilized include the Parent Daily Report Checklist (PDR). Results indicate that there were higher levels of positive reinforcement and accompanying lower levels of children's behavior problems for the intervention group. Effects were strongest for the high-risk group. Limitations include generalization of parenting effects to nonstudy foster children, reliability on a self-reported measure, and lack of follow-up.

Length of controlled postintervention follow-up: None.

Location/Institution: San Diego, CA

Summary: (To include basic study design, measures, results, and notable limitations)
The study used the same sample as Chamberlain et al. (2008). The purpose of the study was to examine the impact of a foster parent training and support intervention, KEEP on placement changes and to determine whether the intervention mitigated placement disruption risks associated with children’s placement histories. Participants were randomly assigned to receive 16 weeks of training, supervision, and support or to casework services as usual. Measures utilized include administrative data from child welfare agency case workers. Child placement exits from foster care were defined as occurring within 200 days of baseline and were based on foster parent report. Positive placement exits were defined as reunion with a parent or relative or adoption. Negative placement exits included another foster placement, more restrictive placement, or running away. Results indicate that the KEEP intervention found that those in the intervention group were nearly twice as likely to experience a positive placement exit as the control group, but were no more or less likely to experience a negative exit as the control group. However, children with a higher number of placements prior to the beginning of the study were more likely to have negative placement exits if they were in the control group but not if they were in the intervention group, which suggested a mitigating effect. The authors note that 70% of the sample experienced no change in placement during the study period. Limitations include generalization of parenting effects to nonstudy foster children and lack of follow-up.

Length of controlled postintervention follow-up: None.

Summary: (To include basic study design, measures, results, and notable limitations)
The study used the same sample as Price et al. (2008). The purpose of the study was to test the effectiveness of KEEP (Keeping Foster Parents Trained and Supported) [now called KEEP] with 700 foster/kinship parents in San Diego County. Participants were randomly assigned to KEEP or control (usual caseworker services) condition. Measures utilized include the Parent Daily Report (PDR) checklist. Results indicate that no differences existed between the behavior rates reported by KEEP parents and those reported by control parents at baseline. At treatment termination, however, foster/kin parents in the KEEP intervention condition reported significantly fewer child behavior problems than those in the control condition. In addition, these changes in child behavior were found to be mediated by changes in parenting behavior. At the five-month postbaseline interview, foster parents who participated in the KEEP groups showed an increase in the proportion of positive reinforcements relative to discipline parenting practices, and this increase predicted a decrease in child problem behaviors. Children of parents in the KEEP group were also found to have higher rates of reunification with biological or adoptive families and fewer placement disruptions than those in the control condition. Limitations include generalization of parenting effects to nonstudy foster children, and lack of follow-up.

Summary: (To include basic study design, measures, results, and notable limitations)
The study used a subset of the same sample as Chamberlain et al. (2008). The purpose of the study was to conduct a within intervention group analysis to test whether caregiver engagement (e.g., participation, homework completion, openness to ideas, apparent satisfaction) in KEEP (Keeping Foster Parents Trained and Supported) [now called KEEP] moderates risk factors for foster child outcomes. Participants were randomly assigned to KEEP or control (usual caseworker services) condition. Measures utilized include the Parent Daily Report Checklist (PDR). Results indicate that caregiver engagement moderates both the influence that the number of prior placements has on increases in child problem behaviors and the risk of negative placement disruption for Hispanics. Limitations include reporter bias and absence of measures focusing on implementation fidelity, adherence to the weekly session curricula, or specific weekly intervention goal; and lack of follow-up.

Length of controlled postintervention follow-up: None.

Location/Institution: Maryland

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to evaluate child behavior change, changes in caregiver parenting style, and permanency and placement stability at baseline and then after the KEEP intervention. KEEP participants were referred by their child welfare caseworker, while comparison participants were recruited via mail and a foster parenting newsletter. Measures utilized include the Parent Daily Report Checklist (PDR), Child Behavior Checklist (CBCL), the Discipline and Supervision Measure, and the Parenting Stress Index Short Form (PSI-SF). Results indicate that there were significant decreases in child behavior problems for participants in KEEP interventions as compared to the comparison group. Additionally, the KEEP group displayed a significant reduction in PDR scores with a display of five fewer problem behaviors reported from baseline to posttest, while the comparison group did not demonstrate any significant change. The decrease of externalizing behaviors for the KEEP group, as measured by the PDR, was not associated with decreased parental stress (as measured by the PSI-SF) and there was not a significant relationship for the KEEP group at posttest for stress and child behavior. There was no change in the discipline and supervision ratio for either the KEEP group or the comparison group and there was no impact of the KEEP training on permanency outcomes for foster and kinship children. In addition, for KEEP parents, placement stability significantly increased between baseline and postintervention when compared to the comparison group. Limitations include nonrandomization of participants, small sample size, and significant differences between the two groups at baseline.

Length of controlled postintervention follow-up: 2 months.

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to (a) examine the effectiveness of KEEP (Keeping Foster Parents Trained and Supported) [now called KEEP] in reducing child behavior problems, as delivered by a community agency; (b) determine if the effects of KEEP generalize to more than one child in the same home; and (c) examine the effectiveness of KEEP in reducing parental stress associated with child behavior problems. Participants were randomly assigned to either KEEP or the control group. Measures utilized include the Parent Daily Report Checklist (PDR). Results indicate that KEEP was effective in reducing child behavior problems when delivered by a community agency. These results expanded prior research on KEEP, revealing that KEEP was effective in reducing the behavior problems of more than one child in the same household and in reducing parental stress levels associated with the behavioral issues of the focal child. Limitations include reliance on parental observation, unequal ethnic distribution of African Americans in the KEEP group, in several instances, the follow-up assessments were conducted on a different child from the one who was assessed at baseline, and lack of follow-up.

Length of controlled postintervention follow-up: None.

Summary: (To include basic study design, measures, results, and notable limitations)
The study used the same sample as Price et al. (2015). The purpose of the study was to examine the effectiveness of the KEEP intervention at reducing behavior problems among children in foster care. Participants were randomly assigned to either the KEEP intervention or usual services. Measures utilized include the Child Behavior Checklist (CBCL). Results indicate that the KEEP intervention was effective at reducing the proportion of children in the borderline group for rule-breaking between baseline and follow-up. The intervention was also effective at reducing internalizing problems, as indicated by reductions in internalizing raw scores and the proportion of children in the borderline group over the course of the intervention. Limitations include the lack of blinding to condition in the study, sole reliance in parent report, and attrition.

Length of controlled postintervention follow-up: None.
