Cognitive Recovery in Socially Deprived Young Children: The Bucharest Early Intervention Project

In a randomized controlled trial, we compared abandoned children reared in institutions to abandoned children placed in institutions but then moved to foster care. Young children living in institutions were randomly assigned to continued institutional care or to placement in foster care, and their cognitive development was tracked through 54 months of age. The cognitive outcome of children who remained in the institution was markedly below that of never-institutionalized children and children taken out of the institution and placed into foster care. The improved cognitive outcomes we observed at 42 and 54 months were most marked for the youngest children placed in foster care. These results point to the negative sequelae of early institutionalization, suggest a possible sensitive period in cognitive development, and underscore the advantages of family placements for young abandoned children.

Differential effects of women's child sexual abuse and subsequent sexual revictimization

This study examines the differential effects of sexual revictimization in a community sample of 248 African-American and White American women, ages 18 to 36. Two classifications of sexual revictimization over the life course were used to assess the effects on later sexual and psychological functioning. The findings suggest that unintended pregnancies and abortions were significantly associated with sexual revictimization. Women who reported more than one incident in both childhood and adulthood were also likely to have multiple partnerships and brief sexual relationships. The findings are discussed within the context of the dynamics of sexual revictimization and its effects. Suggestions are offered for therapeutic strategies with survivors in order to minimize the effects of sexual revictimization.

Institutional Rearing and Psychiatric Disorders in Romanian Preschool Children

OBJECTIVE There is increasing interest in the relations between adverse early experiences and subsequent psychiatric disorders. Institutional rearing is considered an adverse caregiving environment, but few studies have systematically examined its effects. This study aimed to determine whether removing young children from institutional care and placing them with foster families would reduce psychiatric morbidity at 54 months of age. METHOD Young children living in institutions in Bucharest were enrolled when they were between 6 and 30 months of age. Following baseline assessment, 136 children were randomly assigned to care as usual (continued institutional care) or to removal and placement in foster care that was created as part of the study. Psychiatric disorders, symptoms, and comorbidity were examined by structured psychiatric interviews of caregivers of 52 children receiving care as usual and 59 children in foster care when the children were 54 months of age. Both groups were compared to 59 typically developing, never-institutionalized Romanian children recruited from pediatric clinics in Bucharest. Foster care was created and supported by social workers in Bucharest who received regular consultation from U.S. clinicians. RESULTS Children with any history of institutional rearing had more psychiatric disorders than children without such a history (53.2% versus 22.0%). Children removed from institutions and placed in foster families were less likely to have internalizing disorders than children who continued with care as usual (22.0% versus 44.2%). Boys were more symptomatic than girls regardless of their caregiving environment and, unlike girls, had no reduction in total psychiatric symptoms following foster placement. CONCLUSIONS Institutional rearing was associated with substantial psychiatric morbidity. Removing young children from institutions and placing them in families significantly reduced internalizing disorders, although girls were significantly more responsive to this intervention than boys.

The early development of autistic children.

A sample of 74 young autistic children was selected and defined by direct observation of specific behaviors and clinical assessment of the presence or absence of associated pathological conditions. Retrospective developmental data on these children and 38 age-matched normal children were gathered by means of a written inventory completed by the parents when the children were relatively young (mean age less than 4 years). The autistic children were reported to have had significant delays in the development of motor abilities, speech, communication, comprehension, and, to a lesser extent, perception during their 1st and 2nd years.

Animal Source Foods Improve Dietary Quality, Micronutrient Status, Growth and Cognitive Function in Kenyan School Children: Background, Study Design and Baseline Findings

A previous longitudinal three-country study in Egypt, Kenya and Mexico found significant positive associations between intake of animal source foods (ASF) and growth, cognitive development and physical activity. To test for a causal relationship, a controlled school feeding intervention study was designed to test the hypotheses that ASF would improve micronutrient status, growth and cognitive function in Kenyan primary school children. Twelve rural Kenyan schools with 554 children were randomized to four feeding interventions using a local vegetable stew as the vehicle. The groups were designated as Meat, Milk, Energy and Control, who received no feedings. Feeding was carried out on school days for seven terms during 21 mo. Preintervention baseline measures included nutritional status, home food intake, anthropometry, biochemical measures of micronutrient status, malaria, intestinal parasites, health status and cognitive and behavioral measures. The measurements of each child were repeated at intervals over 2 y. Baseline data revealed stunting and underweight in approximately 30% of children and widespread inadequate intakes and/or biochemical evidence of micronutrient deficiencies, particularly of iron, zinc, vitamins A and B-12, riboflavin and calcium. Little or no ASF were eaten and fat intake was low. Malaria was present in 31% of children, and hookworm, amebiasis and giardia were widely prevalent. The outcomes measured were rates of change or increase during the intervention in cognitive function, growth, physical activity and behavior and micronutrient status. Hierarchical linear random effects modeling was used for analysis of outcomes.

Family-expressed emotion, childhood-onset depression, and childhood-onset schizophrenia spectrum disorders: Is expressed emotion a nonspecific correlate of child psychopathology or a specific risk factor for depression?

Expressed emotion (EE) was examined, using the brief Five Minute Speech Sample measure, in families of (1) children with depressive disorders, (2) children with schizophrenia spectrum disorders, and (3) normal controls screened for the absence of psychiatric disorder. Consistent with the hypothesis of some specificity in the association between EE and the form of child disorder, rates of EE were significantly higher among families of depressed children compared to families of normal controls and families of children with schizophrenia spectrum disorders. Within the depressed group, the presence of a comorbid disruptive behavior disorder was associated with high levels of critical EE, underscoring the need to attend to comorbid patterns and subtypes of EE in future research.

Trauma-focused cognitive-behavioral therapy for posttraumatic stress disorder in three-through six year-old children: a randomized clinical trial

BACKGROUND The evidence base for trauma-focused cognitive behavioral therapy (TF-CBT) to treat posttraumatic stress disorder (PTSD) in youth is compelling, but the number of controlled trials in very young children is few and limited to sexual abuse victims. These considerations plus theoretical limitations have led to doubts about the feasibility of TF-CBT techniques in very young children. This study examined the efficacy and feasibility of TF-CBT for treating PTSD in three- through six-year-old children exposed to heterogeneous types of traumas. METHODS Procedures and feasibilities of the protocol were refined in Phase 1 with 11 children. Then 64 children were randomly assigned in Phase 2 to either 12-session manualized TF-CBT or 12-weeks wait list. RESULTS In the randomized design the intervention group improved significantly more on symptoms of PTSD, but not on depression, separation anxiety, oppositional defiant, or attention deficit/hyperactivity disorders. After the waiting period, all participants were offered treatment. Effect sizes were large for PTSD, depression, separation anxiety, and oppositional defiant disorders, but not attention-deficit/hyperactivity disorder. At six-month follow-up, the effect size increased for PTSD, while remaining fairly constant for the comorbid disorders. The frequencies with which children were able to understand and complete specific techniques documented the feasibility of TF-CBT across this age span. The majority were minority race (Black/African-American) and without a biological father in the home, in contrast to most prior efficacy studies. CONCLUSIONS These preliminary findings suggest that TF-CBT is feasible and more effective than a wait list condition for PTSD symptoms, and the effect appears lasting. There may also be benefits for reducing symptoms of several comorbid disorders. Multiple factors may explain the unusually high attrition, and future studies ought to oversample on these demographics to better understand this understudied population.

Placement in Foster Care Enhances Quality of Attachment Among Young Institutionalized Children

This study examined classifications of attachment in 42-month-old Romanian children (N = 169). Institutionalized since birth, children were assessed comprehensively, randomly assigned to care as usual (CAU) or to foster care, and compared to family-reared children. Attachment classifications for children in foster care were markedly different from those in the CAU. Importantly, children placed in foster care before 24 months were more likely to have secure attachments and if placed earlier were less likely to have disorganized or insecure-other attachments. Cognitive status predicted greater likelihood of organized attachment in the CAU and greater likelihood of secure attachment in the foster care and never-institutionalized groups. Foster care is an important intervention to reduce the adverse effects following early deprivation.

Developmental outcomes in children receiving resection surgery for medically intractable infantile spasms.

Two‐year postsurgical developmental outcomes were assessed in 24 children with infantile spasms who underwent resective surgery. The mean age of onset of infantile spasms was 12.0 weeks and the mean age at surgery was 20.8 months. Developmental outcomes were assessed using the Vineland Adaptive Behavior Scales (VABS). There was a significant increase in developmental level at 2 years postsurgery compared with presurgical levels. At 2 years postsurgery only one of the children in this series was severely retarded. The developmental outcomes of patients in the series were better than those in prior studies of symptomatic patients receiving medical treatment for infantile spasms. It is surprising that the children in the UCLA series frequently had developmental outcomes equal to and sometimes superior to other groups of children with infantile spasms, since all the UCLA patients were symptomatic, had neurologic deficits and had failed to respond to adrenocorticotropic hormone (ACTH) and antiepileptic drugs. The 2‐year postsurgery developmental outcomes were best for the children who received surgery, when they were relatively young and who had the highest level of developmental attainments presurgically.

The Impact of Dietary Intervention on the Cognitive Development of Kenyan School Children

Previous observational studies in developing countries have suggested that diet quality, particularly increased animal source food (ASF) consumption, is positively associated with child cognitive development. This report presents findings from a study in rural Kenya, designed to test the impact of three different diets on the cognitive development of school children. Twelve schools with a total of 555 Standard 1 children (equivalent to U.S. Grade 1) were randomized to one of four feeding interventions: Meat, Milk, Energy or Control (no feeding). Feeding continued for seven school terms (21 mo), and cognitive tests were administered before the commencement of feeding and during every other term of feeding. Hierarchical linear random effects models and associated methods were used to examine the effects of treatment group on changes in cognitive performance over time. Analyses revealed that children receiving supplemental food with meat significantly outperformed all other children on the Ravens Progressive Matrices. Children supplemented with meat, and children supplemented with energy, outperformed children in the Control group on tests of arithmetic ability. There were no group differences on tests of verbal comprehension. Results suggest that supplementation with animal source food has positive effects on Kenyan childrens cognitive performance. However, these effects are not equivalent across all domains of cognitive functioning, nor did different forms of animal source foods produce the same beneficial effects. Implications of these findings for supplementation programs in developing countries are discussed.
