Research paper thumbnail of Optimizing foster family placement for infants and toddlers: A randomized controlled trial on the effect of the foster family intervention

We developed an intervention (foster family intervention [FFI]) to tackle these risks. The intervention focuses on foster children below the age of 5 years. The objective was to investigate the effects of FFI on the interactions between foster parents and foster children. A randomized control trial was carried out with a sample of 123 preschool aged children (mean age 18.8 months; 51% boys) and their foster carers. A pretest was carried out 6 to 8 weeks after placement and a posttest one half year later. Interactions were videotaped and coded using the Emotional Availability Scales (EAS). Foster carers were asked to fill in the Dutch version of the Parenting Stress Index. Morning and evening samples of children's salivary cortisol were taken. In the posttest, significantly positive effects were found on the following EAS subscales: Sensi...

However, a considerable part of the children do not show apparent signs of distress, making it difficult for the foster carer to be aware of the amount of stress in their foster child. Potential evidence for using salivary cortisol levels as a dimension to evaluate the amount of stress in young foster children is reviewed. Moreover, the applicability of salivary cortisol in the evaluation of stress-reducing interventions for young foster children is discussed. A systematic review was performed using the databases Medline, Psychinfo, Embase, Ebscohost, and Academic Search Premier. Nine studies were traced in which salivary cortisol was used to measure stress in children placed in family foster care or in adoptive families. Stress in general but also neglect, early loss of a caregiver, a younger age at first placement, and a higher number of placements were associated with an altered hypothalamic-pituitary-adrenal (HPA) axis function in foster children. Moreover, four studies on the effect of stress-reducing interventions on HPA-axis functioning of young foster children were found. These studies suggest that caregiver-based interventions can actually help to normalize the HPA-axis function in foster children, and that such changes co-occur with improved behavioral functioning. Although the results from the papers discussed in this review suggest that diurnal cortisol with a wake up and a bedtime measurement may be a relevant tool to evaluate stress in young foster children, this cannot yet be concluded from the present studies, because statistical data from the studies on foster care and adoption in this review were not robust and researchers used different methods to collect the salivary cortisol. Still, it is noteworthy that all studies did find the same pattern of reduced levels in relation to chronic stress (caused by maltreatment and neglect of the child).

About two-thirds of the placements were short term (less than one year). About three out of four children in family foster care were below the age of 12. The number of children placed in foster families has been increasing annually since 2000 (Factsheet Pleegzorg [Foster Care Fact Sheet], 2011) and in 2010, 57 per cent of the children placed out-of-home full time were living in foster families (Jeugdzorg Nederland [Youth Care, the Netherlands], 2011).

It is important that foster parents recognize the early signs of stress in foster children and learn how to act in a non-threatening and understanding manner. Family-based interventions may help in this. In this paper, we report on a meta-analysis of studies (n = 19) of the effectiveness of such interventions. All studies used a pre-test/posttest design. Both problem behaviour in foster children and the parenting skills of foster parents improved by 30%; however, none of the interventions were specifically intended to help young children (<4 years) to cope with stress. The importance of interventions for young foster children is discussed, as well as the necessary elements these interventions should include.
