RESUMO

This project is a community case study implemented by local professionals and caregivers to improve the quality of caregiving in two Kazakhstan institutions for infants and toddlers. Local professionals first received comprehensive training by an international team experienced in relevant research-based practices, and then the locals trained institutional staff. Over nearly 2 years, one institution progressively implemented changes in three wards and the other institution in one ward. The changes attempted to make the institution more family-like (e.g., smaller groups and fewer and more consistent caregivers) and caregivers behave more parent-like (e.g., more warm, sensitive, responsive interactions and relationships) without changing nutrition or medical care. Of the 45 children given some exposure to the emerging new wards, 11 experienced the fully revised wards for at least 4 months during their first 2 years of life. They displayed substantial increases in their physical growth, especially those entering in their first year of life, in contrast to the unchanging developmental patterns of 165 children who were reared in the two institutions before the ward changes were made. Physical growth is a commonly used standard of developmental well-being in institutions. Research shows it is sensitive to infants' psychosocial environment, and improvements in physical growth are related to children's cognitive and social-emotional development. Although this pilot community case study had only a few infants fully exposed to the complete ward changes and lacked characteristics of a research experiment, these results are consistent with children's developmental improvements reported in larger scientific studies of similar interventions. This project is an example of how some research-based practices are likely to be implemented in communities in the future. Specifically, it shows that local communities can successfully improve the rearing conditions within institutions, which improve the children's development, and may contribute to the success of their subsequent foster placement and adoption.

RESUMO

This study is a post-adoption follow-up of a social-emotional intervention in St. Petersburg, Russian Federation Baby Homes (BHs). Children previously resided in BHs and received Care as Usual (CAU, N=220), Training Only (TO, N=94), or Training plus Structural Changes (T+SC, N=45). This study examined intervention effects 0-6.5 years post-adoption to the USA, at age 9 months to 7 years old. Adoptive parents completed questionnaires on their child's social and behavioral development. Intervention graduates had better attachment security, less indiscriminate friendliness, and fewer behavior problems than CAU graduates. Children who had longer exposure to intervention conditions had better attachment security, but poorer executive function, externalizing and internalizing problems, and competence. Thus, although post-institutionalized children were generally functioning in the normal range in early childhood and effect sizes were small, a social-emotional intervention in institutions is associated with modest benefits to attachment and behavior problems and apparent decrements to executive function.

RESUMO

We review a series of interrelated studies on the development of children residing in institutions (i.e., orphanages) in the Russian Federation or placed with families in the USA and the Russian Federation. These studies rely on a single population, and many potential parameters that typically vary in the literature are similar across studies. The conceptual focus is on the role of early caregiver-child interactions and environmental factors that influence those interactions in children's development. Generally, children residing in institutions that provided minimal caregiver-child interactions displayed delayed physical, cognitive, and social-emotional development. Children and adolescents adopted from such institutions at 18 months of age or older had higher rates of behavioral and executive function problems, even many years after adoption. An intervention that improved the institutional environment by increasing the quality of caregiver-child interactions-without changes in nutrition, medical care, sanitation, and safety-led to substantial increases in the physical, cognitive, and social-emotional development of resident children with and without disabilities. Follow-up studies of children in this intervention who were subsequently placed with USA and Russian families revealed some longer-term benefits of the intervention. Implications are discussed for theoretical understanding of the role of early caregiver-child interactions in development as well as for practice and policy.

RESUMO

The current study addressed whether two institution-wide interventions in St. Petersburg, Russian Federation, that increased caregiver sensitivity (Training Only: TO) or both caregiver sensitivity and consistency (Training plus Structural Changes: T+SC) promoted better socioemotional and cognitive development than did a No Intervention (NoI) institution during the first year of life for children who were placed soon after birth. It also assessed whether having spent less than 9 versus 9 to 36 months with a family prior to institutionalization was related to children's subsequent socioemotional and cognitive development within these three institutions. The Battelle Developmental Inventory (J. Newborg, J.R. Stock, L. Wnek, J. Guidubaldi, & J. Svinicki, 1988) was used to assess the socioemotional and cognitive functioning of children in NoI (n = 95), TO (n = 104), and T+SC (n = 86) at two to three time points during their first 6 to 12 months of residency. Results suggest that improving caregiver sensitivity can improve the cognitive development of infants in the first year of institutionalization whereas improving caregiver consistency in addition to sensitivity is more beneficial for socioemotional development than is sensitivity alone. Similarly, for children in T+SC, longer time with a family prior to institutionalization (consistent caregiver, unknown sensitivity) was associated with better socioemotional, but not cognitive, baseline scores and more rapid cognitive than socioemotional development during institutionalization. These results suggest caregiver sensitivity is more highly related to cognitive development whereas caregiver consistency is more related to socioemotional development in the first years of life.

RESUMO

This study examined the effect of a social-emotional intervention implemented in one St. Petersburg (Russian Federation) institution (called a Baby Home, BH) on the general behavioral development of preterm children (gestational ages of 30-36 weeks) during their first two years of life. The intervention consisted of training caregivers and implementing structural changes to create a more family-like environment. The study included preterm (N = 56) and full-term (N = 93) children from one BH that implemented the intervention and from another BH with no intervention. Children were assessed at 3, 6, 9, 12, 18 and 24 months of age with the Battelle Development Inventory (LINC Associates, 1988). The results showed that the intervention positively influenced the general behavioral development of BH preterm children throughout their first two years of life compared to preterms from the no-intervention BH. Also, results indicated that the intervention effect was developmentally similar for preterm and for full-term children, but preterm children consistently scored lower than full-terms during their first two years living in the BH. In general, our research emphasizes the crucial role of warm, sensitive, and responsive interactions with a constant and emotionally available caregiver for healthy child development for both term and preterm children.

RESUMO

This report describes a secondary analysis of data from a comprehensive intervention project which included training and structural changes in three Baby Homes in St. Petersburg, Russian Federation. Multiple mediator models were tested according to the R.M. Baron and D.A. Kenny () causal-steps approach to examine whether caregiver-child interaction quality, number of caregiver transitions, and group size mediated the effects of the intervention on children's attachment behaviors and physical growth. The study utilized a subsample of 163 children from the original Russian Baby Home project, who were between 11 and 19 months at the time of assessment. Results from comparisons of the training and structural changes versus no intervention conditions are presented. Caregiver-child interaction quality and number of caregiver transitions fully mediated the association between intervention condition and attachment behavior. No other mediation was found. Results suggest that the quality of interaction between caregivers and children in institutional care is of primary importance to children's development, but relationship context may play a less direct mediational role, supporting caregiver-child interactions.

RESUMO

A total of 149 children, who spent an average of 13.8 months in Russian institutions, were transferred to Russian families of relatives and nonrelatives at an average age of 24.7 months. After residing in these families for at least 1 year (average = 43.2 months), parents reported on their attachment, indiscriminately friendly behavior, social-emotional competencies, problem behaviors, and effortful control when they were 1.5-10.7 years of age. They were compared to a sample of 83 Russian parents of noninstitutionalized children, whom they had reared from birth. Generally, institutionalized children were rated similarly to parent-reared children on most measures, consistent with substantial catch-up growth typically displayed by children after transitioning to families. However, institutionalized children were rated more poorly than parent-reared children on certain competencies in early childhood and some attentional skills. There were relatively few systematic differences associated with age at family placement or whether the families were relatives or nonrelatives. Russian parent-reared children were rated as having more problem behaviors than the US standardization sample, which raises cautions about using standards cross-culturally.

RESUMO

This study examined whether interventions in Russian Baby Homes promoting warm, sensitive, and responsive caregiver-child interactions and relationships would be associated with advantages in those children's behavior years after they transitioned to family care. Children (N = 135) who had resided for at least 3 months (M = 13.8 months) in one of three intervention institutions were subsequently placed in Russian families (relatives or non-relatives) for at least 1 year (M = 33.5 months). When children were 1.5-10.8 years of age, parents provided ratings of attachment, indiscriminate friendliness, executive functioning, social-emotional development, and behavior problems. Despite very substantial differences in the developmental status of children at departure from the three institutions, there were fewer than expected significant differences between children from the three institutions at follow-up or as a function of being placed with relatives or non-relatives. Specifically, children reared in the most improved institution displayed less indiscriminate friendliness, were less aggressive/defiant, and had less externalizing behavior. Children from all three institutions who were placed into families at older ages tended to be rated more poorly on some measures. These results suggest that previously institutionalized children adjust well to family life, but improved institutional caregiving can have some persistent benefits over several years in children transitioned to families.

RESUMO

This Special Issue includes articles that contribute to (a) the global research base pertaining to the development of infants and toddlers at risk, primarily those who are institutionalized in lower resource countries; (b) interventions in institutions and to promote family alternatives to institutionalization; and (c) attempts to create modern child welfare systems emphasizing family care in entire states and countries. This introduction places these articles into the broader contexts of the literature in these three domains of interest. Across the world, urbanization, migration, armed conflict, epidemics, and famine disrupt families. Add poverty, abuse, neglect, and parental incapacity due to substance abuse and mental health problems, and the result is millions of children without parental care who come under governmental responsibility, often to be reared in institutions, and at risk for long-term developmental deficiencies and problems. Over the last 2 decades and especially recently, national and international governments and nongovernment organizations have increased efforts to help such children, especially those in low-resource countries. Two types of efforts have been made: one to improve the quality of care provided by institutions and the other to minimize the use of institutions and promote family residential care alternatives. The latter effort includes preventing family separations in the first place, reunification of children with birth families, and developing systems of kinship care, foster care, and adoption. This Special Issue of IMHJ is devoted to reports pertaining to issues in the research knowledge base, program practices, and countrywide policies for infants and young children at risk. We attempt in this introduction to place these reports in the broader context of this field, identify their unique contributions, and highlight lessons learned that can contribute to improved care practices and better child welfare systems.

RESUMO

Behavior problems were studied in fifty 5- to 8-year-old children transferred from a socioemotionally depriving Russian institution to domestic families. Results indicated that the postinstitutional (PI) sample as a whole had higher clinical/borderline behavior problem rates on the parent-reported Child Behavior Checklist for Ages 6-18 (T.M. Achenbach & L.A. Rescorla, 2001) aggressive and lower rates on the withdrawn/depressed and internalizing problems scales than did non-institutionalized (non-I) children reared in Russian families. Compared with the U.S. standardization sample, PI children had significantly higher rates for aggressive, externalizing, and social problems; the non-I children had higher rates for withdrawn/depressed and internalizing problems; and both groups had higher rates for rule-breaking behavioral problems. PI children placed in domestic families at 18 months or older had higher rates of problems than did the U.S. non-I standardization sample, but children placed at younger ages did not. PI children transferred to nonbiological families had lower rates of problems compared to U.S. norms than did children transferred to biological families. Thus, prolonged early socioemotional deprivation was associated with a higher percentage of behavior problems in children placed in domestic families, especially if transferred to biological families.

RESUMO

This article reports the maintenance of one of the largest interventions conducted in St. Petersburg (Russian Federation) orphanages for children birth to 4 years using regular caregiving staff. One orphanage received training plus structural changes, another training only, and a third business as usual. The intervention produced substantial differences between these institutions on the Home Observation for Measurement of the Environment (HOME) Inventory and on the Battelle Developmental Inventory scores for children. These institutional differences in HOME scores (N = 298) and Battelle scores for children (N = 357) departing the institutions for families in St. Petersburg and the United States were maintained for at least 6 years after the intervention project. This result may be associated with certain features of the intervention and activities conducted during the follow-up interval.

RESUMO

Children in two institutions in St. Petersburg (Russian Federation) experienced ward transitions, one in which caregivers were trained to provide sensitive, responsive caregiving and one that conducted business as usual. A third institution eliminated transitions, received the same training, and implemented a variety of structural and employment changes designed to promote improved caregiver-child interactions and relationships. While the no-transition comprehensive intervention group of children steadily improved in Battelle Developmental Inventory (LINC Associates, 1988) scores across all age intervals, the children in the institution who encouraged some positive caregiver-child interactions improved before and after, but not during, an age period that involved a transition. In contrast, the no-treatment group displayed no developmental changes across any age period with or without a transition. These results suggest that the common institutional practice of ward transitions to new peers and caregivers is potentially disruptive to infants' and toddlers' general development, but primarily in a context in which some degree of caregiver-child sensitive and responsive interactions are encouraged.

RESUMO

An estimated 8 million children, mostly birth to approximately 6-8 years of age, live in institutions worldwide. While institutional environments vary, certain characteristics are common, including relatively large groups; high children:caregiver ratios; many and frequently changing caregivers; homogeneous grouping by age and disability status; periodic graduations to new groups of peers and caregivers; and an "institutional style of caregiving" that minimizes talking, provides rather dispassionate perfunctory care, and offers little warm, sensitive, contingently-responsive caregiver-child interactions. The development of children in residence is usually delayed, sometimes extremely so, in every physical and behavioral domain. Although efforts are being made in many countries to care for children without permanent parents in family environments (e.g., domestic adoption, foster and kinship care, reunification with biological parents), it is not likely that transitions to family alternatives will be completed in all countries in the near future; thus, institutions are likely to exist for many years if not decades. But institutions need not operate in the current manner; they can be modified to be substantially more family-like in structure and in the behavior of caregivers. Research indicates that when such changes are made the development of children, both typically developing and those with special needs, is improved substantially. Based on the available literature and the authors' experience, this paper describes steps that can be taken to implement such changes in residential institutions for infants and young children.

RESUMO

This study provides descriptive empirical information on the environments, organizational structure, caregivers, caregiver-child interactions, and children's general behavioral development and problem behaviors from three institutions for young children in Central America. While the institutions were clean, they were physically sparse and had Infant-Toddler Environmental Rating Scale (ITERS; T. Harms, D. Cryer, & R. Clifford, 2006) and Early Childhood Environmental Rating Scale (ECERS; T. Harms, R. Clifford, & D. Cryer, 2005) scores that averaged 1.62 (7 = highest). Caregivers provided routine caregiving with limited emotion, responsiveness, support, empathy, or guidance. Caregivers tended to work long hours and then were off 2 to 3 days, and children periodically graduated to new wards, so there was little stability of caregivers in children's lives. Children's average Battelle Developmental Inventory Total Developmental Quotient = 58 to 63, which would be considered mildly-moderately retarded in noninstitutional U.S. populations; no child scored >90, 80% scored <70, and nearly half scored <60. Children displayed high frequencies of indiscriminate friendliness, noncompliance, and provocative and aggressive/violent behaviors. These data and that of a few other studies represent the only comprehensive, empirical description of institutions for young children, which constitutes the independent variable (institutionalization) for a burgeoning literature on postinstitutional adopted children. Results are consistent with the hypothesis that a lack of warm, sensitive, contingently responsive interactions with relatively few consistently available caregivers may be a major contributor to delayed contemporary development and persistent deficits and problems observed in some postinstitutional adopted children and adolescents.

RESUMO

This paper reports the construction and pilot reliability, validity, and psychometric properties of a new caregiver-child rating scale that emphasizes caregiver-child social-emotional interactions and relationships. While the scale was developed and studied in the context of orphanages for young children, it potentially could be used in non-residential early care and education settings as well as for parent-child interactions in the home. The intent was to assess a few dimensions that comprehensively cover the range of caregiver-child social-emotional interactions and relationships but could be administered in a relatively short period of time in a variety of situations and would not require extensive coder training, manuals, or materials. Results showed that the scale can be reliably administered even using observation periods as short as five minutes, reliability was replicated over seven different coders working in three different orphanages, and ratings of caregivers were similar across different types of caregiving activities (i.e., feeding, dressing/bathing, free play) and for caregivers attending to children birth to 4 and 4 to 8 yrs. of age. In the orphanage context, factor analyses showed the scale primarily reflects caregiver-child mutual engagement and relationship with subordinate components of caregiver punitiveness and caregiver- vs. child-directed behaviors and intrusiveness.

RESUMO

A pilot intervention that emphasized training and technical assistance to promote warm, sensitive, and responsive one-on-one caregiver-child interactions primarily during feeding and bathing/changing was implemented using regular staff in a depressed orphanage for children birth to approximately 8 years of age in Latin America. Despite a variety of unanticipated irregularities in the implementation of the intervention, many beyond the researchers' control, ward environments improved; caregivers displayed more warm, sensitive, and responsive interactions with children; and children improved an average of 13.5 developmental quotient (DQ) points after 4+ months' exposure to the completed intervention. Furthermore, 82% of the children had DQs greater than 70 before the intervention, but only 27.8% did so afterward. Although the training for all caregivers was aimed at children birth to 3 years, the number of different caregivers was reduced, and technical assistance was provided only to caregivers serving children less than 3 years, younger and older children (3-8 years) improved approximately the same amount. However, children who were transitioned from a younger to an older ward during the intervention improved less than did children who remained in either a younger or an older ward, the first evidence suggesting that the common orphanage practice of periodically graduating children from one homogeneous age group to another may impede their development. The study is consistent with others that have shown that orphanages can be changed, and increases primarily in warm, sensitive, responsive caregiver-child interactions can produce improvements in children's development.

RESUMO

This article describes a unique study that attempts to promote positive social-emotional relationships and attachment between caregivers and children in orphanages in St. Petersburg, Russia. The children who reside in these orphanages are typically between birth and 48 months of age; approximately 50% are diagnosed with disabilities, and approximately 60% leave through foreign adoption. Initially, their orphanage caregivers showed a high level of current anxiety and depression and were detached from and communicated little with the children. Likewise, during baseline observations, the children demonstrated poor attachment behaviors such as indiscriminant friendliness, lack of eye contact with adults, aggression, and impulsive behavior. Two interventions were used in a quasiexperimental design: (a) training of caregivers to promote warm, responsive caregiving and (b) staffing and structural alterations to support relationship building, especially increasing the consistency of caregivers. The methodology required that both the training and staffing interventions be provided to one orphanage, only the training to a second, and neither to a third. (At any one time, ns = 80-120 in each condition.) Initial informal observations reveal positive behaviors for both the caregivers and the children, such as increased two-way conversations, animated and enthusiastic emotional responses, and positive social and language interactions. Early data analyses show an increase in the consistency and stability of caregivers and increased scores for caregivers on every subscale of the HOME Scales. Children showed improvements in physical growth, cognition, language, motor, personal-social, and affect, with children having severe disabilities improving the most. The implications of these findings suggest that training staff with modest educational backgrounds and structural changes are effective, can increase socially responsive caregiving behaviors, and improves social interactions of children, at least temporarily. ©2005 Michigan Association for Infant Mental Health.

RESUMO

The benefits for children at the Pittsburgh site of the federal Comprehensive Child Development Program (CCDP) were examined as a function of family welfare status (Aid to Families with Dependent Children; AFDC) and SES. The CCDP was the largest attempt by the federal government to provide two-generation, case-managed, comprehensive services to low-income families. Participating families could set their own goals and choose services to achieve them, but relatively few services were directed specifically at children. Results showed that more Pittsburgh families in the CCDP treatment group (N = 120) left AFDC than in the control group (N = 120), consistent with results from a national evaluation of the CCDP. Children whose families were on AFDC regardless of treatment group had lower mental test scores, even after controlling for family SES, a result suggesting that AFDC receipt over and above income level was associated with poorer child mental performance. The CCDP was associated with higher children's mental scores plus improvements over time in achievement scores only for children in families who were not on AFDC, even after controlling for SES. Such parents were more likely to choose parenting and child goals and services, which in turn were associated with higher child mental scores. In contrast, parents who were on AFDC tended to choose adult-centered goals and services, which did not benefit children. Therefore, in contrast to the national evaluation, which found no benefits of the CCDP for children, these analyses showed that the CCDP did produce benefits for children whose parents were not on AFDC, who tended to choose parenting and child services.
