Biological Context
Within the biological context,
gender was frequently mentioned as a defining characteristic. In most studies, girls were more represented in foster care than boys (Armsden et al.
2000; James et al.
2012; Lee and Thompson
2008; Scholte
1997; Strijker et al.
2005,
2008; Van den Bergh and Weterings
2010; Vanderfaeillie et al.
2013; Vanschoonlandt et al.
2013). Some researchers found a slightly higher percentage of boys, up to a maximum of 56 % (Holtan et al.
2005; Minnis et al.
2006; Wilson et al.
2004). Conversely, in family-style group care boys were mostly represented (Gardeniers and De Vries
2011; Lee and Thompson
2008; Van der Steege
2012). Here the reported percentages of boys varied from 54 to 62 %. However, very little evidence was found that the gender differences between foster care and family-style group care are statistically significant. Only Lee and Thompson (
2008) reported a significant difference in the number of boys in these two categories. Finally, the vast majority of the children in residential care were boys; the percentages varied from 59 to 72 % (Hussey
2006; Hussey and Guo
2002; James et al.
2012; Lee and Thompson
2008; Scholte
1997; Scholte and Van der Ploeg
2010). Nevertheless, neither James et al. (
2012) nor Scholte (
1997) found any statistically significant differences between foster and residential care concerning gender differences.
With respect to
age of admission, children in foster care were on average between 7 and 11 years old (Barber and Delfabbro
2009; Bernedo et al.
2014; James et al.
2012; Minnis et al.
2006; Strijker et al.
2008,
2002). Only Tarren-Sweeney (
2013) found an average age of 3.5 years at entry into care, although this presumably concerns the age at
first placement. In family-style group care, the mean age of admission varied from 10 to 12 years old (Gardeniers and De Vries
2011; Van der Steege
2012). According to Lee and Thompson (
2008), children in family-style group care were significantly older than children in foster care when placed out-of-home. However, they only included children aged 8 years and older in their research population, which might have increased the reported mean age of admission. Lastly, the average age of admission for residentially placed children appear to be the highest of the three settings. The reported mean ages varied from 10 to 14 years (Hussey
2006; James et al.
2012; Scholte
1997; Scholte and Van der Ploeg
2010). In comparison with foster children, residentially placed children were reported to be significantly older at admission (James et al.
2012; Scholte
1997). Curtis et al. (
2001) made the same conclusion based on their literature review. Only two studies specifically reported age at the time of
first placement into out-of-home care: Yampolskaya et al. (
2014) found an average age of 6.4 years (SD = 5.4), while Hussey and Guo (
2002) reported an average of 4.9 (specifically for residentially placed children). It should be noted that the ambiguity in reported figures is presumably due to differences in research methodology between the included studies.
A third defining characteristic of children in care was their
physical health. Yampolskaya et al. (
2014) demonstrated that six percent of the children had physical health problems. However, James et al. (
2012) reported substantially more chronic health problems for children in both foster and residential care: they found that approximately one-third of the children have these problems. Likewise, Tarren-Sweeney (
2008) indicated physical health problems in 30 % of the foster children. The comparability of the findings related to physical health problems is limited by the heterogeneity of these problems’ definition. Tarren-Sweeney (
2008) for example referred to specific physical health problems such as epilepsy and motor neurological conditions, whereas both James et al. (
2012) and Yampolskaya et al. (
2014) used a broader definition like “the presence of any serious chronic physical health conditions that adversely impact the child’s daily functioning” (Yampolskaya et al.
2014, p. 196).
Lastly, some studies reported the
average IQ of children in care. A meta-analysis of IQ delays in orphanages by Van IJzendoorn (
2008) showed a mean IQ of 84.4 (SD = 16.8), which can be classified as “below average” intellectual functioning. Hussey and Guo (
2002) also found a mean IQ of this order for residentially placed children (M = 82.5, SD = 17.4). On the other hand, a longitudinal survey of residentially placed children by Scholte and Van der Ploeg (
2010) showed a mean IQ of 90.2, which reflects lower levels of “average intelligence.” Unfortunately, no study was found reporting the mean IQ of foster children and children placed in family-style group care. De Swart et al. (
2012) confirmed in their meta-analysis, that even to date remarkable few studies include IQ as moderator, whilst literature data have shown that this factor partly affects the child’s cognitive abilities and learning style. However, a retrospective study by Tarren-Sweeney (
2008) concluded that nearly 23 % of foster children had an intellectual disability. In general, available data indicate that a lower IQ is associated with higher levels of psychopathology (Hussey and Guo
2002; Tarren-Sweeney
2008).
Individual Context
According to Bhatti-Sinclair and Sutcliffe (
2012), risk factors within the individual context are the main reason for out-of-home placement. In the literature, a frequently mentioned risk factor was the presence of
emotional problems. A recent study of Yampolskaya et al. (
2014) found that more than half (53 %) of the children in care had such problems. With regard to foster care, the reported percentage of foster children with emotional problems varied from 14 to 45 %, mostly as measured with the Child Behavior Checklist (CBCL) (Armsden et al.
2000; Bernedo et al.
2014; James et al.
2012; Minnis et al.
2006; Scholte
1997; Sullivan
2008; Tarren-Sweeney
2013; Vanderfaeillie et al.
2013). Within residential care, this prevalence rate varied from 39 to 57 % (James et al.
2012; Scholte
1997; Scholte and Van der Ploeg
2010). No information was found regarding emotional problems in children placed in family-style group care. When comparing the number of children with emotional problems in foster and residential care, James et al. (
2012) did not find any statistically significant differences. However, Scholte (
1997) demonstrated that residentially placed children showed emotional problems significantly more often than foster children.
Considering
behavior problems, the number of foster children with a score in the (borderline) clinical range on the externalizing problems scale of the CBCL covered a broad area, varying from 34 to 63 % (Armsden et al.
2000; Bernedo et al.
2014; James et al.
2012; Minnis et al.
2006; Tarren-Sweeney
2013; Vanderfaeillie et al.
2013; Vanschoonlandt et al.
2013). At least one-third of foster children had these problems. In contrast, Scholte (
1997) reported much lower scores on the different subscales belonging to the externalizing problems scale, varying from 10 to 15 %. This difference is probably due to the dating of the research. Last decades, more children with severe psychosocial problems presumably have been admitted to foster care instead of being placed in more restricted types of care [in accordance with the UN guidelines (
2009, December 18)]. In family-style group homes, 40–60 % of the children showed behavior problems, especially hyperactive and impulsive or defiant and antisocial behavior (Van der Steege
2012). Lee and Thompson (
2008) found that children in family-style group homes had (with statistical significance) more behavior problems than those placed in treatment foster care. Finally, behavior problems were reported in more than half of the children at admission to residential care (James et al.
2012; Scholte
1997; Scholte and Van der Ploeg
2010). The same studies also reported that residentially placed children showed (with statistical significance) more behavior problems in comparison with foster children. As claimed by Esposito et al. (
2013), the degree of behavior problems increases the risk of an out-of-home placement, in particular for older children.
The behavior problems seem in part to be related to
attachment problems (Newton et al.
2000; Vanschoonlandt et al.
2012). Therefore, the quality of the attachment development of children in care is a third relevant factor within the individual context. A recent review of Pritchett et al. (
2013) concluded that the severeness of attachment problems was related to negative placement outcomes. Nevertheless, little detailed information was found concerning the prevalence of the attachment problems of children placed out-of-home. The definition of attachment problems also appeared to be very heterogeneous. Concerning foster care, Tarren-Sweeney (
2013) found symptoms in 20 % of the foster children that specifically related to complex attachment problems that were not reducible to other psychiatric disorders. Strijker et al. (
2008) reported a slightly lower percentage of 14 %, but they only included foster children with an actual Diagnostic Manual of Mental Disorder classification for reactive attachment disorder. In family-style group care, attachment problems were reported in 50 % of the children (Van der Steege
2012). Finally, Scholte and Van der Ploeg (
2010) found signs of social and emotional detachment in 31 % of the residentially placed children. In this study, the Social Emotional Detachment Questionnaire (in Dutch called VFO) was used (Scholte and Van der Ploeg
2007). They have similarly inventoried the rate of children with insecure attachment patterns based on the children’s case files and found a percentage of 52 % (Scholte and Van der Ploeg
2010). Generally speaking, on average one-third of the children in care have attachment problems. This was also confirmed in a meta-analysis by Van IJzendoorn et al. (
1999), who demonstrated that 38 % of the children (aged 0–4 years) in “normal” middle class, nonclinical groups in North America showed insecure attachment patterns.
A fourth relevant factor was the
cognitive development and related
school performance. As noted previously, both aspects are affected by the child’s intelligence (De Swart et al.
2012). Problems in cognitive development and poor school performance seem to be the least common in foster care; at most one-third of the foster children had poor academic performance (Bernedo et al.
2014; James et al.
2012; Minnis et al.
2006; Scholte
1997; Tarren-Sweeney
2008). Likewise, according to Van der Steege (
2012) found that approximately one-third of the children in family-style group care demonstrated cognitive problems such as social skills problems and attention problems. With regard to residential care, the reported percentages of children with cognitive problems showed more variability. One-fifth to one-half of the children appeared to have school-related problems, such as poor school motivation or delays in language, cognition, or adaptive behavior (James et al.
2012; Scholte
1997; Scholte and Van der Ploeg
2010). Zima et al. (
2000) found a relationship between caregiver scores in the clinical range on the CBCL and a history of suspension or expulsion. In total, they reported that 14 % of the children in care experienced at least one suspension or expulsion (Zima et al.
2000). These researchers also reported that 23 % of the children in care had reading and math skill delays and that 13 % repeated at least one grade (Zima et al.
2000). Unfortunately, no distinction was made between foster and residentially placed children. James et al. (
2012) did not find any significant differences in cognitive development and school performance when comparing residentially placed and foster children. In contrast, Scholte (
1997) found significantly more school-related problems in residentially placed children than in foster children. Because different aspects of cognitive development and school performance were measured in the two studies, their results are not directly comparable. In general, both Pritchett et al. (
2013) and De Swart et al. (
2012) state that little is known about the school performance, cognitive skills, and IQs of out-of-home placed children in relation to placement outcomes. Furthermore, Pritchett et al. (
2013) conclude that the existing literature shows conflicting results concerning whether risk factors in this area enhance the chance of negative placement outcomes.
Finally, a study of Tarren-Sweeney (
2008) indicated that 36 % of foster children were prescribed any type of
medication; most common ones being mood-altering (“psychotropic”) and asthma medications. For children in residential care, Hussey and Guo (
2002) reported a very high percentage (92 %) of children using psychotropic medication. No studies related to the use of medication in family-style group care were found.
Family Context
Numbers concerning
parental divorce were searched first. The percentage of divorced parents (43 %) in family-style group care reported by Van der Steege (
2012) approximated the overall divorce rate in the Netherlands, which is 37 % (Centraal Bureau voor de Statistiek
2013). Moreover, 14 % of the children with divorced parents lived in a stepfamily (Van der Steege
2012). The percentage of divorced parents in both foster and residential care is many times higher. In foster care, Scholte (
1997) reported a percentage of 84 %. Similarly, in residential care the percentage of divorced parents was indicated as being between 72 and 80 % (Scholte
1997; Scholte and Van der Ploeg
2010). It should be noted that all of the reported percentages are based on Dutch research populations. Also related to the family composition is the percentage
deceased parents. Numbers were only found for family-style group care. Van der Steege (
2012) reported that 9 % of the mothers and 18 % of the fathers of placed children were deceased.
Next to family composition, the degree of family problems was a relevant defining characteristic in children placed out-of-home. Complex and multiple family problems are a main reason for out-of-home placement of young children (aged 0–9 years) in particular (Esposito et al.
2013; Yampolskaya et al.
2014). A commonly mentioned risk factor in this area was child abuse. Concerning
physical or emotional child abuse, approximately 5–45 % of foster children have a history of this type of abuse (Bernedo et al.
2014; James et al.
2012; Lee and Thompson
2008; Scholte
1997; Strijker et al.
2008; Tarren-Sweeney
2008). Only Minnis et al. (
2006) reported a much higher percentage of emotional child abuse in their Scottish sample, namely 77 %. On the other hand, the reported percentage of 5 % by Vanschoonlandt et al. (
2013) was actually very low in comparison to other studies concerning foster care. When distinguishing between physical and emotional child abuse among foster children, physical abuse seems to be less common: up to one-third of them have a history of this type of abuse. Regarding family-style group care, Van der Steege (
2012) reported a similar percentage of 28 % of children being physically or emotionally abused. In contrast, Lee and Thompson (
2008) stated that 52 % of the children in family-style group care experienced physical or emotional abuse. Lastly, the percentage of residentially placed children with a history of this type of abuse varied from 15 to 63 % (Hussey
2006; Hussey and Guo
2002; James et al.
2012; Lee and Thompson
2008; Scholte and Van der Ploeg
2010). It is noteworthy that the Hussey and Guo’s (
2002) reported percentage of 63 % was almost twice as high as other reported percentages for residentially placed children. This is possibly due to the specific research population in that study.
Another common type of child abuse was
physical or emotional neglect. In short, the literature suggests that at least one-quarter to one-third of out-of-home placed children experience neglect, although the presented percentages differ considerably. For foster children, in general one-half to two-thirds of the children have been neglected within their family of origin (Bernedo et al.
2014; James et al.
2012; Lee and Thompson
2008; Strijker and Knorth
2009; Tarren-Sweeney
2008; Yampolskaya et al.
2014). Only Vanschoonlandt et al. (
2013) found a much lower percentage of neglected foster children, namely 21 %. Lee and Thompson (
2008) found that foster children had a history of neglect significantly more often than children placed in family-style group care. When it comes to this latter type of care, about 40 % of the children have experienced physical neglect, emotional neglect, or both within their family of origin (Lee and Thompson
2008; Van der Steege
2012). In residential care, findings demonstrated percentages of neglected children that varied from 26 to 69 % (Hussey and Guo
2002; James et al.
2012; Lee and Thompson
2008; Scholte and Van der Ploeg
2010). Barber and Delfabbro (
2009) stated that in general terms, child neglect mainly occurs in young children. Both Barber and Delfabbro (
2009) and Spinhoven et al. (
2010) also found that neglected children have an increased risk of other forms of child abuse. In addition, (emotionally) neglected children are most vulnerable for lifetime mood disorders like anxiety or depression in the future (Spinhoven et al.
2010). It therefore seems very important to be alert for signs of child neglect in the event of family problems.
A third form of child abuse was
child sexual abuse. In foster care, most studies concluded that about 10 % of foster children have been sexually abused in the past (Bernedo et al.
2014; James et al.
2012; Scholte
1997; Strijker et al.
2008; Tarren-Sweeney
2008). At the same time, Minnis et al. (
2006) and Lee and Thompson (
2008) respectively found percentages of 28 and 29 % in relation to foster children. As far as children in family-style group care are concerned, very little information was found: only a study of Lee and Thompson (
2008) reported a percentage of 17 %. This study additionally showed that foster children had a history of sexual abuse significantly more often than children placed in family-style group care. For residentially placed children, the percentage of those who have experienced child sexual abuse in the past appears to be around 10 % (James et al.
2012; Scholte
1997; Scholte and Van der Ploeg
2010). Remarkably, Hussey (
2006) reported that almost half of residentially placed children have been sexually abused, whereby girls were almost one and a half times more at risk (61 %) than boys.
Next to child abuse,
domestic violence was also a relevant risk factor. In foster and family-style group care, domestic violence occurs within about one-third of the families of origin (Lee and Thompson
2008; Strijker et al.
2008; Tarren-Sweeney
2008; Yampolskaya et al.
2014). Lee and Thompson (
2008) even reported percentages of 41 % for foster children and 31 % for children in family-style group care, with statistically significant differences between both percentages. As far as residentially placed children are concerned, only Hussey and colleagues reported domestic violence figures. They concluded that such violence occurs within about one-sixth of the families of origin (Hussey
2006; Hussey and Guo
2002).
Furthermore, the presence of
parental mental illness could be identified as an important risk factor within the family context. In relation to all three types of care, at least one in three parents show mental illness (Hussey and Guo
2002; Lee and Thompson
2008; Scholte
1997; Scholte and Van der Ploeg
2010; Strijker et al.
2008; Van der Steege
2012). However, Scholte and Van der Ploeg (
2010) reported that a much higher percentage (61 %) of the parents (of residentially placed children) showed mental illness, whereby mothers clearly more often had these problems (49 %) than fathers (12 %). Likewise, findings of Minnis et al. (
2006) demonstrated that 52 % of the biological mothers (of foster children) showed mental illness. Lee and Thompson (
2008) reported that the percentage of children in foster care with mentally ill biological parents (45 %) was significantly higher than for children in family-style group care (20 %). In comparing the percentages of mental illness between parents of children in foster and residential care, Scholte (
1997) found no significant differences. It should be noted that because of the differences in severeness and kinds of parental mental illness, comparison between the three types of care is limited. In the same vein, this heterogeneity presumably have caused the broad range in percentages of parental mental illness.
Lastly some literature data considered parental substance abuse and parental incarceration. With reference to
parental substance abuse, in all three types of care at least one in five parents have alcohol or drug problems (Hussey
2006; Hussey and Guo
2002; Lee and Thompson
2008; Strijker et al.
2008; Yampolskaya et al.
2014). Hussey and Guo (
2002) even reported drug abuse in 49 % of the parents of children in residential care. Regarding
parental incarceration, Hussey and Guo (
2002) demonstrated that slightly more than 10 % of the residentially placed children had an incarcerated parent. Lee and Thompson (
2008) found a similar percentage (16 %) of incarcerated parents for children in family-style group care and a (statistically significant) higher percentage for foster children (26 %).
Care History Context
To start with, the
mean number of previous placements was an important defining characteristic. For the Netherlands, we found no literature related to the mean number of placements or repeated referrals to the three care modalities concerned. A large study of Yampolskaya et al. (
2014), however, suggested that almost a quarter of the children in care have already experienced a previous placement, of which 29 % have been admitted at least four times since their first referral to youth care. For foster children, some studies reported a mean of 3.1–3.4 previous placements (Lee and Thompson
2008; Tarren-Sweeney
2013). Other studies related to foster care reported a lower mean of previous placements that lied between 1.3 and 1.8 (James et al.
2012; Strijker et al.
2008). Concerning children in family-style group care, Lee and Thompson (
2008) concluded that these children have experienced significantly fewer previous placements than foster children, specifically 2.0 placements. Finally, previous placements in residential care appear to be the highest, with an average of at least four (Hussey
2006; Hussey and Guo
2002; James et al.
2012). James et al. (
2012) stated that residentially placed children experienced significantly more placements than foster children.
With regard to
admission from birth home, almost half of the foster children were placed directly from their birth home into foster care during their first out-of-home placement (Barber and Delfabbro
2009; Holtan et al.
2005; Strijker et al.
2008). The former residences of the other half of the foster children in these studies were not clearly reported. Concerning children placed in family-style group care, findings of Gardeniers and De Vries (
2011) demonstrated that 23 % of these children entered from their birth home and that approximately the same percentage (22 %) entered from foster care. Most children (48 %) were placed into family-style group care from residential care (Gardeniers and De Vries
2011). Lastly, about half of the children entered residential care from their birth home (Scholte
1997; Scholte and Van der Ploeg
2010), although it could not be determined from the study whether or not this represented a first out-of-home placement. Next to admission from birth home, Scholte (
1997) reported that 20 % of the residentially placed children came from a foster family setting while 28 % came from another residential institution.
A final defining characteristic was the percentage of children in
child protective service custody. When a child is at risk for abuse or neglect or has suffered serious physical or emotional damage, the child can be removed from the custody of his or her parents or guardians by a governmental agency (Arizona Office of the Auditor General
2008). In foster care, the number of children in child protective service custody appears to be the lowest; the reported percentages varied from 57 to 59 % (Strijker et al.
2002; Van den Bergh and Weterings
2010; Vanschoonlandt et al.
2013). A distinction can be made between family supervision and a suspension of parental rights over the child. In the case of suspension, the child is placed under the permanent legal guardianship of the government, and the caseworker has rights and responsibility for the care, custody, and control of the child (DPHHS Human Resources Division
2010). When distinguishing between the two types of custody, Strijker et al. (
2002) reported that 19 % of foster children were under family supervision while 13 % were under permanent legal guardianship. In family-home care, at least two-thirds of the children were in child protective service custody, mostly under family supervision (Gardeniers and De Vries
2011; Lee and Thompson
2008; Van der Steege
2012). Finally, approximately 75 % of the children in residential care were in child protective service custody (Hussey
2006; Lee and Thompson
2008; Scholte and Van der Ploeg
2010). Similarly, a review of Frensch and Cameron (
2002) also concluded that residentially placed children were mostly under child protective service custody.
Social-Cultural Context
A first important factor in the social-cultural context was
peer relations. Results of Scholte (
1997) showed that 8 % of foster children experienced problems in this area. He also concluded that such problems were less likely to occur in foster care than in residential care, where a percentage of 46 % was found (Scholte
1997). Minnis et al. (
2006) reported in contrast a much higher percentage of 63 % foster children with peer problems in their Scottish sample, based on the Strengths and Difficulties Questionnaire. As far as children in family-style group care are concerned, Van der Steege (
2012) reported that 29 % of the children had peer problems.
Ethnic background was also a factor that was mentioned often. In general, about half of the children in care have a Caucasian ethnic background (Armsden et al.
2000; Yampolskaya et al.
2014). Nevertheless, the figures concerning ethnic background are hardly comparable due to both the heterogeneity of the defined ethnic groups and the diversity within those groups (Bhopal and Donaldson
1998). For example, “White” or “Caucasian” is often used in American literature; the relevant directive from the U.S. Office of Management and Budget includes people from Europe, North Africa, and the Middle East in the definition of this term (Bhopal and Donaldson
1998). In contrast, the governmental body of Statistics Netherlands considers people from both North Africa and the Middle East to be “non-Western” category (Centraal Bureau voor de Statistiek
2000). This non-Western category also includes people from Africa, Latin America, and Asia. Therefore, the percentages related to ethnic background in our scoping review should be considered as indicative. Several studies reported that more than half of the American children in foster care had a Caucasian ethnic background (James et al.
2012; Lee and Thompson
2008). In contrast, Minnis et al. (
2006) reported that 99 % of foster children had a Caucasian ethnic background, but this percentage relates to a Scottish sample and thus is not directly comparable with American foster children. With respect to residentially placed American children, almost half had a Caucasian ethnic background (Hussey
2006; James et al.
2012). In the Netherlands, Scholte and Van der Ploeg (
2010) reported a slightly higher percentage of 77 % for residentially placed children. Lastly, a Caucasian ethnic background mostly occurred in family-style group care both in the United States and the Netherlands (Gardeniers and De Vries
2011; Lee and Thompson
2008; Van der Steege
2012). On the other hand, Lee and Thompson (
2008) found no statistically significant differences in ethnicity between foster children and children in family-style group care.
A final factor within this context was
social-
economic status. James et al. (
2012) reported that over 80 % of the children in foster care lived in poverty, based on the number of children with insurance through Medicaid (which is an American social health care program for families and individuals with low income and limited resources). Likewise, more than 80 % of the children in residential care had a low social-economic status (Hussey
2006; James et al.
2012). In a Swedish sample, Franzén et al. (
2008) reported lower percentages for out-of-home placed children who are of primary school age. Over 12 % of the mothers were at or below the poverty line. We found no results relating to the social-economic status of children in family-style group care. Overall, both Esposito et al. (
2013) and Franzén et al. (
2008) concluded that adverse social-economic factors put young children at risk for out-of-home placement.
