Anna Freud's contributions to our knowledge of child development. An overview.

Anna Freud's contribution to our understanding of child development, normal and abnormal, is so substantial, extensive, diverse, and rich in its implications that its summary is beyond the scope of a single presentation. Accordingly this paper concentrates on some contributions that have especially influenced the author, on later, comparatively neglected writings, and on works that looked at what had gone before as well as what lay ahead. But, it is argued, Anna Freud's contributions cannot be assessed simply in terms of her writings. The creation of the Hampstead Child Therapy Course and Clinic, along with its leadership and the stimulation it gave to others both there and world wide, is regarded as her greatest achievement.

Effects of prenatal and postnatal methylmercury exposure from fish consumption on neurodevelopment: outcomes at 66 months of age in the Seychelles Child Development Study.

CONTEXT: Human neurodevelopmental consequences of exposure to methyl-mercury (MeHg) from eating fish remain a question of public health concern. OBJECTIVE: To study the association between MeHg exposure and the developmental outcomes of children in the Republic of Seychelles at 66 months of age. DESIGN: A prospective longitudinal cohort study. PARTICIPANTS: A total of 711 of 779 cohort mother-child pairs initially enrolled in the Seychelles Child Development Study in 1989. SETTING: The Republic of Seychelles, an archipelago in the Indian Ocean where 85% of the population consumes ocean fish daily. MAIN OUTCOME MEASURES: Prenatal and postnatal MeHg exposure and 6 age-appropriate neurodevelopmental tests: the McCarthy Scales of Children's Abilities, the Preschool Language Scale, the Woodcock-Johnson Applied Problems and Letter and Word Recognition Tests of Achievement, the Bender Gestalt test, and the Child Behavior Checklist. RESULTS: The mean maternal hair total mercury level was 6.8 ppm and the mean child hair total mercury level at age 66 months was 6.5 ppm. No adverse outcomes at 66 months were associated with either prenatal or postnatal MeHg exposure. CONCLUSION: In the population studied, consumption of a diet high in ocean fish appears to pose no threat to developmental outcomes through 66 months of age.

Stress and mood disorders during pregnancy: implications for child development.

Recent research suggests that stress, anxiety, and depression during pregnancy may have an impact on how the child develops. In this article, the central literature supporting this hypothesis is reviewed. Next, studies from our laboratory showing that differences in fetal heart rate patterns are associated with women's anxiety and depressive symptomatology are reviewed. The data indicate that we can detect fetal markers associated with alterations in women's mood that also are linked to differences in the neurobiological substrate of the fetus' emerging emotion regulation system. Identifying such fetal characteristics someday may contribute to the early detection and prevention of predispositions to childhood risk for emotional problems and even psychopathology.

Marital discord and early child development.

As part of a prospective study on the neuropsychiatric development of children born at varying degrees of organic and psychosocial risk, the effect of marital discord on the cognitive and social-emotional development of 315 first-born children into two parent households was investigated. Both the children and the quality of the parental relationship were evaluated when the children were 3 months and 2 years of age. The findings show that marital discord at 3 months does not affect child performance at 3 months, or at 24 months. Marital discord at 2 years does affect the emotional well-being of the 2 year olds, i.e. it is accompanied by a significant rise in psychopathological symptoms. When the effect of the stability of marital strife from the first assessment to the second was studied, a significant increase of behaviour problems and decrease in cognitive performance was found in the group of children whose parents' marital situation had deteriorated and failed in the meantime but surprisingly not in the group with chronic discordant relationships. Conversely, poor child performance and emotional adjustment improved with a positive change in the parental relationships. Analysis shows that negative marital change goes hand in hand with a decrease in parenting skills which affect children more adversely than their counterparts whose parents had a history of marriage and child-rearing problems. Further study of the course of marital relationships and child development at the next research waves (4.5 and 8 years) will show which results are of long-term versus short-term relevance.

The importance of regressive changes in the development of the nervous system: towards a neurobiological theory of child development.

In this paper we propose that theories of early personality development be revised to consider knowledge of neurodevelopment. Research findings are reviewed that have established the presence of regressive changes in the normal development of the brain. These regressive changes, consisting of neuronal death and process and synapse elimination, are theoretically linked to three precursors of personality: sex differences, temperamental traits and perceptual-motor coordination. Evidence supporting these hypotheses is provided from studies examining how the effects of genetic, environmental, and experiential factors on brain development may determine the development of these personality features.

Child development: what do parents expect?

Expectations of future development were assessed in parents of non-disabled children (n = 240) using the Predictive Adaptive Ability Questionnaire (PAAQ). The reliability estimate for the overall PAAQ was 0.90, with a test-retest reliability of 0.99 and an interrater reliability of 0.83. Parental expectations did not significantly differ from normal adaptive ability developmental standards. Longitudinal examination of parental expectations and their influence on child development and the impact of chronic illness on such expectations is recommended.

Integrated Child Development Services scheme (ICDS) and its impact on nutritional status of children in India and recent initiatives.

Integrated Child Development Services (ICDS) scheme is the largest national programme for the promotion of the mother and child health and their development in the world. The beneficiaries include children below 6 years, pregnant and lactating mothers, and other women in the age group of 15 to 44 years. The package of services provided by the ICDS scheme includes supplementary nutrition, immunization, health check-up, referral services, nutrition and health education, and pre-school education. The distribution of iron and folic acid tablets and megadose of vitamin A is also undertaken, to prevent iron deficiency anaemia and xerophthalmia respectively. The scheme services are rendered essentially through the Anganwadi worker (AWW) at a village centre called "Anganwadi". The ICDS had led to (i) reduction in prevalence of severe grades of malnutrition and (ii) better utilization of services of national nutritional anaemia prophylaxis programme and the national programme for prevention of nutritional blindness due to vitamin A deficiency by ICDS beneficiaries. The ICDS scheme is being modified continuously to strengthen the programme.

Child development knowledge, childrearing attitudes, and social support among first- and second-time adolescent mothers.

This paper compares the parenting characteristics of first- and second-time adolescent mothers. Using a case control design, immediately after delivery and at two months postpartum we administered a pretested questionnaire to 51 second-time adolescent mothers, 47 first-time adolescent mothers, and 25 second-time adult mothers. The questionnaire measured the subject's social support system, contraceptive use, and education level. Scales measuring stressful life events, knowledge of child development, and childrearing attitudes were included. The adolescent groups were similar except that significantly more second-time adolescent mothers dropped out of school (p less than or equal to 0.05). Greater maternal education and higher infant five-minute Apgar scores were associated with less negative childrearing attitudes immediately after the birth (p less than or equal to 0.05). At two months postpartum, the age of the father and the time he spent with the child were associated with positive childrearing attitudes (p less than or equal to 0.05). Increased paternal involvement and completion of high school may enhance adolescent attitudes toward childrearing and improve mother-child relations.

Integrated Child Development Services Scheme and nutritional status of Indian children.

The Integrated Child Development Services (ICDS) Scheme is one of the major National Human Resource Development Programmes of the Government of India. The programme completed 18 years of its effective operational duration on 2 October 1993. During this period we have conducted various baseline surveys, multicentre longitudinal and periodic studies, and unicentre special study projects to determine the impact of the programme on the nutritional status of children aged 0 to < 6 years and evaluate the coverage of the scheme. The children with normal nutrition in ICDS blocks constituted 50 per cent of the surveyed population in 1976 in comparison to 75 per cent observed in baseline data of 1990 survey. There was a highly significant decrease in severely malnourished children from 21 per cent in 1976 to 7 per cent in 1990. The benefit of the programme was evident in all sections of the society including Scheduled Castes, Scheduled Tribes, Backward and Minority communities. The nutritional services (supplementary nutrition, Vit. A, Iron, and Folic Acid) coverage of the children increased from 25 per cent in 1976 to 53 per cent in 1985 in ICDS blocks in comparison to 42 per cent in non-ICDS blocks, while that for pregnant and lactating women increased from 17 per cent and 14 per cent in 1976 to 25 per cent and 26 per cent 1985, respectively.

Cumulative environmental risk in substance abusing women: early intervention, parenting stress, child abuse potential and child development.

OBJECTIVE: To assess the relationship between cumulative environmental risks and early intervention, parenting attitudes, potential for child abuse and child development in substance abusing mothers. METHOD: We studied 161 substance-abusing women, from a randomized longitudinal study of a home based early intervention, who had custody of their children through 18 months. The intervention group received weekly home visits in the first 6 months and biweekly visits from 6 to 18 months. Parenting stress and child abuse potential were assessed at 6 and 18 months postpartum. Children's mental and motor development (Bayley MDI and PDI) and language development (REEL) were assessed at 6, 12, and 18 months postpartum. Ten maternal risk factors were assessed: maternal depression, domestic violence, nondomestic violence, family size, incarceration, no significant other in home, negative life events, psychiatric problems, homelessness, and severity of drug use. Level of risk was recoded into four categories (2 or less, 3, 4, and 5 or more), which had adequate cell sizes for repeated measures analysis. DATA ANALYSIS: Repeated measures analyses were run to examine how level of risk and group (intervention or control) were related to parenting stress, child abuse potential, and children's mental, motor and language development over time. RESULTS: Parenting stress and child abuse potential were higher for women with five risks or more compared with women who had four or fewer risks; children's mental, motor, and language development were not related to level of risk. Children in the intervention group had significantly higher scores on the PDI at 6 and 18 months (107.4 vs. 103.6 and 101.1 vs. 97.2) and had marginally better scores on the MDI at 6 and 12 months (107.7 vs. 104.2 and 103.6 vs. 100.1), compared to the control group. CONCLUSION: Compared to drug-abusing women with fewer than five risks, women with five or more risks found parenting more stressful and indicated greater inclination towards abusive and neglectful behavior, placing their infants at increased risk for poor parenting, abuse and neglect. Early home-based intervention in high-risk families may be beneficial to infant development.

An evaluation of efforts to educate mothers about child development in pediatric office practices.

The efforts expended by pediatricians in a variety of private practice settings to educate mothers of first-born children about child behavior and development were examined in relation to various outcome measures of mother and child functioning over a time period of one-and-a-half years. Mothers learned more about child development in group settings than in solo practice settings, but differences between medical groups with and without nurse practitioners were not significant. Mothers receiving care from pediatricians who made at least a moderate effort to teach, learned more about child development, described more use of positive contact with their children, and felt they were helped more in their childrearing efforts than did mothers receiving care from pediatricians who made little effort to teach. However, there were no significant differences in measures of the child's developmental status related to physician teaching input, and mothers exposed to higher levels of teaching input reported more behavioral problems with their children. The most important predictor of the child's developmental status at 18 months of age was the amount of positive contact between mother and child at one year. It is suggested that the effects of changing the frequency of well-child visits on the mothers' interaction patterns with their children and on their feelings of being supported by the physician be ascertained before making recommendations about the optimal number of such visits.

Prenatal methylmercury exposure from ocean fish consumption in the Seychelles child development study.

INTRODUCTION: Exposure to methylmercury (MeHg) before birth can adversely affect children's neurodevelopment. The most common form of prenatal exposure is maternal fish consumption, but whether such exposure harms the fetus is unknown. We aimed to identify adverse neurodevelopmental effects in a fish-consuming population. METHODS: We investigated 779 mother-infant pairs residing in the Republic of Seychelles. Mothers reported consuming fish on average 12 meals per week. Fish in Seychelles contain much the same concentrations of MeHg as commercial ocean fish elsewhere. Prenatal MeHg exposure was determined from maternal hair growing during pregnancy. We assessed neurocognitive, language, memory, motor, perceptual-motor, and behavioural functions in children at age 9 years. The association between prenatal MeHg exposure and the primary endpoints was investigated with multiple linear regression with adjustment for covariates that affect child development. FINDINGS: Mean prenatal MeHg exposure was 6.9 parts per million (SD 4.5 ppm). Only two endpoints were associated with prenatal MeHg exposure. Increased exposure was associated with decreased performance in the grooved pegboard using the non-dominant hand in males and improved scores in the hyperactivity index of the Conner's teacher rating scale. Covariates affecting child development were appropriately associated with endpoints. INTERPRETATION: These data do not support the hypothesis that there is a neurodevelopmental risk from prenatal MeHg exposure resulting solely from ocean fish consumption.

PCBs, DDE, and child development at 18 and 24 months.

To determine whether perinatal exposure to "background" levels of polychlorinated biphenyls (PCBs) or dichlorodiphenyldichloroethene (DDE) affected child development, we followed a cohort of children through the age of 2 years; 676 were tested at 18 months and 670 at 24 months with the Bayley Scales. Transplacental and cumulative exposures from breast milk to both chemicals were estimated for each child from analyses of breast milk and other samples. Bayley testing was done without knowing the chemical levels. At 18 and 24 months, adjusted scores on the psychomotor scales were 4 to 9 points lower among children in the top fifth percentile of transplacental PCB exposure, significantly so at 24 months. There were no consistent effects apparent from exposure to PCBs through breast milk, nor from DDE exposure. We conclude that there is a small delay in motor maturation attributable to transplacental exposure to PCBs that is still detectable at 24 months. There is no evidence of an effect from the larger but later exposure through breast milk, although effects may emerge as the children age.
