Cognitive appraisals, coping strategies, and support resources as correlates of parenting and infant development

By applying R. S. Lazarus's (1993) theoretical model, the authors explored the dynamics of stress and coping as central mechanisms underlying parenting adjustment and infant development. Longitudinal assessment of 140 primiparous mothers included measures of cognitive appraisals of parenting, coping strategies used, and supportive coping resources at pregnancy and 1 month, 6 months, and 12 months postpartum. Maternal outcome measures of adjustment included maternal well-being, parental efficacy, and observed behaviors of caregiving and affiliation. Infant developmental outcome was measured by the Bayley Scales of Infant Development (N. Bayley, 1993). All measures of the stress and coping model showed systematic developmental changes across the transition to parenthood as well as relative stability of individual differences. In addition, the stress and coping variables were found to have additive and interactive effects in predicting both maternal adjustment and infant development.     

Early mother and infant antecedents of Bayley Scale Performance at 21 months.

Investigated the predictability of performance on the Mental scale of the Bayley Scales of Infant Development (BSID) at 21 mo from characteristics of infants and mothers. 25 low-risk mother–infant pairs participated. Mother's level of education, a responsive maternal attitude, and 3-mo smiling and eye contact predicted infant performance on the Mental scale of the BSID.

Prenatal and perinatal influences on long-term psychomotor development in offspring of diabetic mothers

OBJECTIVE: Our purpose was to assess to what extent disturbances in antepartum maternal metabolism and perinatal complications and morbidities contribute to poorer psychomotor development in offspring of diabetic mothers. STUDY DESIGN: One hundred ninety-six pregnant women and their singleton offspring participated in this prospective cohort-analytic study. Ninety-five women had pregestational diabetes mellitus, and 101 women had gestational diabetes mellitus. Serial estimates of circulating maternal fuels were obtained throughout each index pregnancy along with detailed records of the perinatal course and outcome. Offspring were administered the psychomotor development index of the Bayley Scales of Infant Development at age 2 years and the Bruininks-Oseretsky Test Of Motor Proficiency at ages 6, 8, and 9 years. Tests were performed blinded to the mother's antepartum metabolic status, and perinatal history, and the child's previous test scores. Partial correlations and analyses of covariance were used to control for other influences and confounds, such as family socioeconomic status, racial or ethnic origin, patient group (i.e., pregestational or gestational diabetes mellitus), and sex of child. RESULTS: Children's average score on the Bruininks-Oseretsky test at ages 6 to 9 years correlated significantly with maternal second (p < 0.02) and third trimester (p < 0.001) beta-hydroxybutyrate. There was also a borderline association between the children's scores on the psychomotor development index at age 2 years and maternal third-trimester beta-hydroxybutyrate levels (p = 0.06). No other correlations approached significance. CONCLUSIONS: Intrauterine metabolic experiences continue to influence the neurodevelopmental course in offspring of diabetic mothers. Prevailing practices in diabetes management and obstetric and neonatal care appear to effectively mitigate the potential long-term effects of most perinatal complications and morbidities. Management and obstetric and neonatal care appear to effectively miltigate the potential long-term effects of most perinatal complications and morbidities.     

Maternal assessment of infant development: associations with alcohol and drug use in pregnancy

Surveillance by parental concern has been advocated to assess whether formal child developmental testing is needed. To determine whether alcohol intake or illicit drug use in pregnancy is associated with differences in maternal perception of infant development, mothers with acknowledge alcohol and drug habits during pregnancy (N = 120) were interviewed at 11 months' postpartum, within 1 month before infant testing by use of the Bayley Scales of Infant Development. Women with heavy alcohol intake during pregnancy (> 3.5 oz absolute alcohol per week) were 15-fold more likely to overestimate their infant's mental development (P < 0.05), whereas mothers using illicit drugs were 4-fold more likely to overestimate their infant's physical development (P = 0.02). Given the frequent denial of substance abuse, we suggest that health care providers be cautious in accepting a lack of parental concern about a child's development and rely more heavily on formal testing, particularly in high-risk populations.     

Relationship of prenatal cocaine exposure and maternal postpartum psychological distress to child developmental outcome

Maternal cocaine use during pregnancy can affect the infant directly through toxic effects or indirectly through cocaine's influence on maternal psychological status. We followed 160 cocaine exposed and 56 nonexposed infants and their mothers identified at birth through interview and/or urine screen. Although cocaine exposure defined the groups, infant exposure to alcohol, marijuana, and tobacco was allowed to vary. Infants were 99% African American and poor. All mothers completed the Brief Symptom Inventory (BSI) and infants were given the Bayley Scales of Mental (MDI) and Motor (PDI) Development at a mean corrected age of 17 +/- 8 months. Both MDIs (94 +/- 17 vs. 103 +/- 16) and PDIs (101 +/- 16 vs. 108 +/- 12) were lower for cocaine exposed infants. Psychological distress was greater in cocaine using mothers. Hierarchical multiple regression was used to assess the relative effects of gestational age, maternal psychological distress, and cocaine and polydrug exposure on infant outcomes. Both psychological distress and cocaine and alcohol exposure predicted lower MDIs after controlling for prematurity. Neither psychological distress nor alcohol exposure predicted motor outcome, while cocaine had a significant effect. Tobacco and marijuana exposure were unrelated to outcome. These findings provide further support for direct effects of cocaine and alcohol on infant development as well as highlight the need for studies to document maternal psychological factors, which may increase child risk for poorer outcomes.     

Neurodevelopmental outcomes of Ugandan infants with HIV infection: An application of growth curve analysis.

Neurodevelopmental outcomes of human immunodeficiency virus Type 1 (HIV-1)-infected infants of non-drug-using mothers were assessed in a controlled, prospective study from birth to 24 months with 3 groups: 61 infants of HIV-infected mothers, 234 uninfected infants of HIV-infected mothers (seroreverters), and 115 uninfected infants of uninfected mothers. Compared with seroreverters; and uninfected infants, HIV-infected infants demonstrated lower mental and motor development on the Bayley Scales and greater deceleration in their rate of motor development. HIV-infected infants with abnormal neurologic exams had lower motor and mental test scores and lower rates of motor Bayley Scales scores than their HIV-infected counterparts with normal neurologic exams. Contrary to prediction, no group differences in mean performance or growth rates were found on visual information processing on the Fagan Test of Infant Intelligence.

Infants of postpartum depressed mothers: Temperament and cognitive status.

This study examined the association of postpartum depression with specific infant characteristics. Twenty-five diagnosed depressed and 25 nondepressed mothers and their 2-month-old infants participated in the study. The mothers completed measures of infant temperament and difficulty associated with infant care, and the infants were assessed using the Bayley Scales of Infant Development. Group comparisons indicated that, compared with the infants of the nondepressed mothers, the infants of the depressed women were less competent cognitively and expressed more negative emotions during the testing. The depressed mothers perceived their infants as more difficult to care for and more bothersome than did the nondepressed mothers, but did not attribute these difficulties to the temperament of their infants. These findings suggest that postpartum depression is associated with an identifiable pattern of infant behavior that may exacerbate depressed women's mood.

The Diabetes in Early Pregnancy Study: beta-hydroxybutyrate levels in type 1 diabetic pregnancy compared with normal pregnancy. NICHD-Diabetes in Early Pregnancy Study Group (DIEP). National Institute of Child Health and Development

OBJECTIVE: The objective was to assess relationships between beta-hydroxybutyrate (beta-OHB) level and pregnancy outcome in human pregnancy in light of the fact that high levels of beta-OHB cause malformations and growth retardation in in vitro studies. RESEARCH DESIGN AND METHODS: We analyzed beta-OHB in prospectively collected specimens from the National Institute of Child Health and Human Development-Diabetes in Early Pregnancy Study, in gestational weeks 6-12 in diabetic (n = 204-239) and nondiabetic (n = 316-332) pregnant women. RESULTS: Levels of beta-OHB in diabetic women were 2.5-fold higher than in nondiabetic pregnant women at 6 weeks' gestation and declined to 1.6-fold above nondiabetic women by 12 weeks' gestation (P < 0.0001 at all times). beta-OHB was positively correlated with glucose levels (P < 0.0001) in diabetic mothers, probably reflecting degree of diabetic control. beta-OHB correlated inversely with glucose (P < 0.0003) (gestational week 6 only) in nondiabetic mothers, possibly reflecting caloric intake. beta-OHB tended to be lower (not higher) in diabetic and nondiabetic mothers with malformed infants or pregnancy losses, but the difference was not statistically significant. beta-OHB in diabetic mothers at 8, 10, and 12 weeks correlated inversely with birth weight (P = 0.004-0.02), even after adjusting for maternal glucose levels. beta-OHB levels were also generally lower in diabetic mothers of macrosomic infants, and week 12 ultrasound crown-rump measurements were inversely related to beta-OHB levels. CONCLUSIONS: The lst trimester beta-OHB is significantly higher in diabetic than nondiabetic pregnant women. In both groups, beta-OHB tended to be lower, not higher, in mothers who had a malformed infant or pregnancy loss. beta-OHB was inversely related to crown-rump length and birth weight. The modest beta-OHB elevation in the 1st trimester of reasonably well-controlled diabetic pregnancy is not associated with malformations, probably because beta-OHB levels causing malformations in embryo culture models are 20- to 40-fold higher. The mechanism of the beta-OHB association with impaired fetal growth is unknown.     

Infant communicative development: Evidence from adoptive and biological families for genetic and environmental influences on rate differences.

Parent/infant relationships were investigated in 50 biological families selected to provide a control group for a previous adoption study by the 1st author and colleagues (1981) of rate differences in communicative development in infancy. Measures of infant communicative competence, adult cognitive abilities, and aspects of the home environment were constructed and evaluated for both control and adoptive groups (including the birth mothers of the infant adoptees). The Bayley Scales of Infant Development was also administered. The addition of the control infants and families to the overall adoption design permitted testing of a number of genetic and environmental relationships previously documented between birth parents and adoptees and between adoptive parents and adoptees. Path analyses incorporating all 100 control and adopted 1-yr-olds confirmed that parental general intelligence is moderately predictive of rate of infant communicative development and that this relationship is due to shared genetic influence. Although few relationships with the home environment were documented within either group, data suggest that parental imitation of infant vocalizations may represent a direct environmental influence unconfounded by shared genetic variance.

Infant perceptual, cognitive, and motor behaviours as predictors of subsequent cognitive and language development.

In a longitudinal study, 80 preterm and 68 full-term infants were administered the Bayley Scales of Infant Development at 4, 8, 12, 18, and 24 mo; the Uzgiris-Hunt Scale at 4, 8, 12, and 18 mo; the Caldwell Inventory of Home Stimulation (HOME) at 12 mo; the Reynell Language Scales at 24, 30, and 36 mo; and the Stanford-Binet Intelligence Scale at 30 and 36 mo. There were significant correlations between the early infants tests and the Stanford-Binet and the Reynell Language Scales at 30 and 36 mo, indicating continuities in cognitive development. The perceptual items of the Bayley were significant predictors early in development; at 8 mo the conceptual items became predictive, and at 12 mo the language items became predictive. The Psychomotor Development Index of the Bayley and the Means and Object Concept subtests of Uzgiris-Hunt administered at 4 and 8 mo were significantly correlated with subsequent language development. The HOME scale was significantly correlated with cognitive and language scores, particularly language comprehension. There appear to be substantial continuities between infant behaviors and cognitive and language abilities in early childhood.

Infant predictors of preschool and adult IQ: A study of infant twins and their parents.

Measures of infant cognitive development in 208 pairs of twins were evaluated at 7, 8 and 9 months of age. Measures included the Fagan Test of Infant Intelligence (FTII), visual expectation measures of reaction time and anticipation, selected items from the Bayley Scales of Infant Development, variety of vocalizations, Bayleys's Infant Behavior Record (IBR), and others. The midparent IQ scores were regressed on the infant measures to evaluate the likelihood of predicting later IQ. Significant predictors were the FTII, visual expectation, IBR, vocalizations, and a composite of selected Bayley items. These measures were also the best predictors of the infants' intelligence scores on the Bayley at 1 and 2 years of age and on the Stanford-Binet at 3 years of age.

In situ detection of myocardial infarction in pig by measurements of aspartate aminotransferase (ASAT) activity in the interstitial fluid

Recent studies have suggested that the fetal dysmorphogenesis in diabetic pregnancies is associated with an increase in embryonic oxygen-free radicals. This excess of oxygen-free radicals may result from either overproduction or decreased clearance by the enzymatic scavenging mechanism. However, there are no in vivo data on the activity of embryonic oxygen-free radical scavenging enzymes. The purpose of the current study is to investigate whether this increase in embryonic oxygen-free radicals is the result of a change in the activity of the fetal oxygen-free radical scavenging/antioxidant enzymes during pregnancy complicated by maternal diabetes in an in vivo rat model. Thirty-six Sprague-Dawley rats were randomly assigned to one of two study groups: nondiabetic control and an untreated diabetic group. On day 12, fetuses were examined for crown-rump lengths, somite numbers, and external anomalies. The activity of fetal oxygen-free radical scavenging enzymes, including superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT), were determined. The untreated diabetic group of rats had a significantly higher mean blood glucose level than that of the nondiabetic controls and also a significantly lower weight gain, higher resorption rate, smaller embryonic size with lower total protein content, and a approximately 6-fold increase in the rate of fetal neural tube defects compared to the nondiabetic controls. Superoxide dismutase activity was significantly reduced in the embryos with neural tube defects regardless of maternal diabetic status (2.25 +/- 0.83 vs. 1.17 +/- 0.04 u/mg protein; P < 0.05). Glutathione peroxidase and catalase activity were significantly reduced in malformed versus normal-formed embryos of nondiabetic mothers (GPX-2.68 +/- 1.15 vs. 4.46 +/- 1.12 mu/mg protein, CAT -1.67 +/- 0.53 vs 2.49 +/- 0.61 u/mg protein respectively; P < 0.01). However, overall catalase activity was increased in embryos of diabetic mothers as compared to controls. Two-way analysis of variance identified fetal malformations as the variance associated with reduced fetal SOD activity, whereas maternal diabetes was associated with the increase in fetal catalase activity. Neither neural tube defect nor maternal diabetes was found to be the variable affecting fetal GPX activity, Fetal oxygen-free radical scavenging enzymes respond differently to the adverse environment created by maternal diabetes during pregnancy. Defects in embryonic SOD and catalase activity, regardless of maternal diabetic status, may reduce the ability of the fetus to clear free oxygen radicals, thereby exposing it to an increased oxidative load that may cause fetal dysmorphogenesis. The diabetic state of the mothers did not decrease embryonic activity of any of the scavenging enzymes. Therefore, although excess oxidative load, as observed in diabetes, may cause tissue injury and embryopathy, the mechanism does not appear to be a diabetes-induced reduction in the action of the scavenging enzymes.     

Security of attachment, compliance, and maternal training methods in the second year of life.

36 children and their mothers were first observed when the child was 12 mo old, using the M. D. Ainsworth et al (1978) Strange Situation; based on their behavior in this setting, 22 infants were judged to be secure in attachment to their mothers. At age 21 mo, children (and mothers) were observed again, using the Bayley Scales of Infant Development, an interview, and a laboratory play session. Children's measures were (a) proportions of maternal commands obeyed and actively disobeyed, (b) internalized controls, (c) cooperation with an adult woman playmate and the Bayley examiner, and (d) mother's report on home behavior. Secure infants were significantly more compliant and cooperative than the others on every 21-mo measure. Mothers of secure infants exhibited more gentle physical interventions and used warmer tones in giving commands than did mothers of nonsecure infants. Children's compliance and cooperation with the mother and with other persons were positively related to the mother's warmer tones and gentler physical interventions.

Rapid assessment of infant predictors of adult IQ: Midtwin-midparent analyses.

Assessed infant predictors of adult IQ with same-sex infant twins (114 pairs) and their parents. The midtwin–midparent design permits the rapid assessment of infant measures to predict later behavior, because the midparent score serves as a proxy for the infant's potential score at maturity. At 5, 7, and 9 mo, Ss were observed on the Fagan Test of Infant Intelligence, hand preference, vocalizations, selected Bayley Scales of Infant Development items, and a modified Bayley Infant Behavior Record. At 8 mo, Ss received the Visual Expectation Paradigm and an auditory discrimination task. Their parents received the Wechsler Adult Intelligence Scale—Revised (WAIS—R). Some infant measures, indicative of information processing, language ability, and temperament, predicted midparent IQ. This study extended and partially replicated findings from a previous midtwin–midparent cohort (L. F. DiLalla et al; see record 1991-04066-001).

Maternal coping strategies and emotional distress: Results of an early intervention program for low birth weight young children.

Several questions were examined with Infant Health and Development Program (IHDP) data (N?=?843). Are effects of intervention services found for maternal emotional distress and coping strategies, and are these effects different for different groups of mothers? Do maternal distress, coping, and life events moderate (or mediate) the intervention effects reported earlier for children's test scores and behavior problems (IHDP, 1990)? The intervention reduced maternal distress, especially for women with less than a high school education. Maternal distress did not moderate or mediate the influence of the intervention on child outcomes. Maternal coping was not influenced by the intervention and did not moderate the influence of the intervention on child outcomes. Life events moderated the influence of the intervention on children's test scores; the intervention was more effective for children whose mothers had fewer life events.

Neurocognitive sequelae of infants of diabetic mothers.

On the basis of animal models, it was hypothesized that infants of diabetic mothers (IDMs) would be at risk for suffering damage to the hippocampus primarily because of fetal iron deficiency, chronic hypoxia, and hypoglycemia. This, in turn, may result in impairments in recognition memory at a young age. To test this model, the memory of 6-month-old IDMs and control infants was evaluated with electrophysiological (event-related potential [ERP]) and behavioral (looking time) measures. At 12 months, the Bayley Scales of Infant Development was administered. Our ERP measures showed robust evidence consistent with memory deficits in the IDMs. In contrast, the looking time measures and the Bayley exam failed to distinguish between the groups. From these results it was concluded that the ERP, but not the behavioral, measures are able to detect, in an at-risk population, deficits in recognition memory that are thought to be mediated by damage to the hippocampus.

Mother's insightfulness regarding their infants' internal experience: Relations with maternal sensitivity and infant attachment.

This study examined the associations among mothers' insightfulness into their infants' internal experience, mothers' sensitivity to their infants' signals, and infants' security of attachment to their mothers. The insightfulness of 129 mothers of 12-month-old infants was assessed by showing mothers 3 videotaped segments of observations of their infants and themselves and interviewing them regarding their infants' and their own thoughts and feelings. Interviews were classified into 1 insightful and 3 noninsightful categories. Mothers' sensitivity was assessed during play sessions at home and at the laboratory, and infant-mother attachment was assessed with the Strange Situation. Mothers classified as positively insightful were rated as more sensitive and were more likely to have securely attached children than were mothers not classified as positively insightful. Insightfulness also accounted for variance in attachment beyond the variance explained by maternal sensitivity. These findings add an important dimension to research on caregiving, suggesting that mothers' seeking of explanations for the motives underlying their infants' behavior is related to both maternal sensitivity and infant attachment.

Introduction to the special series.

Infant attachment to the caregiver may serve as the base for later social, affective, and cognitive development, but clinical research focused on the origins of competent or dysfunctional behavior has been rare. This special series examines attachment as it relates to maternal processes and infant temperament and as it predicts later adaptive and maladaptive functioning. Nonpathological attachment to inanimate objects is described, and the impact of maternal drinking, child abuse, and infant prematurity on attachment is considered. The study of the early bonds between infant and caregiver promises to extend our awareness of normal and psychopathological development.

Pre- and postbirth antecedents of 2-year-old attention, capacity for relationships, and verbal expressiveness.

46 families were followed from midpregnancy to child age 2 yrs. At midpregnancy mothers were interviewed and completed the Wechsler Adult Intelligence Scale (WAIS) and the Minnesota Multiphasic Personality Inventory (MMPI). Various forms of data were collected at 1, 3, 6, 12, and 24 mo postbirth, including observations in the home and infant assessment, using the Bayley Scales of Infant Development. Results indicate that the pattern of antecedents and correlates differed as a function of the criteria chosen. Thus, the 2-yr-olds' attention was not significantly influenced by the concurrent parent stimulation of cognitive and verbal experiences, but the most impressive determinants consisted of 2 forms of early child behavior, 1-mo positive vocalization and 6-mo attention, as well as prebirth maternal IQ. By contrast, the 2-yr-olds' modulation of aggression was not only an integral part of a concurrent set of relationship variables but the significant antecedents stressed prebirth parent characteristics having a high potential for promoting a positive, emotionally responsive relationship with the child (warmth, adaptation–competence, husband–wife adaptation), whereas the postbirth antecedents were highlighted by parents responding successfully to the needs of an increasingly soothable infant.

Contextual basis of maternal perceptions of infant temperament.

To elucidate the differential saliency of infant emotions to mothers across interactive contexts, the authors examined the moderating role of observed infant affect during interactions with mother in the relation between maternal and laboratory-based ratings of infant temperament. Fifty-nine developmentally healthy 9-month-old infants were judged for degree of infant positive, infant negative, and mother-infant mutually positive affect during the course of object-focused and routine home-based activities with mother. Mothers completed the Infant Behavior Questionnaire (M. K. Rothbart, 1981), and infants underwent the Laboratory Temperament Assessment Battery (H. H. Goldsmith & M. K. Rothbart, 1999). Results revealed that maternal and observer ratings of infant negativity converged when infants manifested high degrees of negative affect during routine home-based activities. Maternal and observer ratings of infant positivity converged when infants experienced low mutually positive affect during play. These findings support the hypothesis that maternal perceptions are based on mothers' experiences with their infants but that the salience of infant temperamental characteristics to mothers varies across emotion and interactive context.
