Infant attachment strategies, infant mental lag, and maternal depressive symptoms: predictors of internalizing and externalizing problems at age 7

The predictive relations between assessments in infancy and parent- and teacher-reported behavior problems at age 7 were investigated within a low-income sample. Infancy assessments indexed family adversity, parent-infant interaction at home, infant attachment, infant anger-distress at home, gender, and cognitive functioning. Among children at age 7 identified by teachers as highly externalizing, 83% were both disorganized in their attachment behavior in infancy and below the national mean in mental development scores at 18 months, compared with 13% of nonexternalizing children. Avoidant attachment behavior in infancy was associated with later internalizing symptoms rather than with externalizing symptoms. The behavior problem data reported by mother suggested the possibility of attachment-related biases in maternal report data. The results indicate that child mental lag in the context of a disorganized attachment relationship constitutes 1 early step on the pathway to school-age externalizing behavior.     

Infants at social risk: Relations among infant maltreatment, maternal behavior, and infant attachment behavior.

Fifty-six 12-mo-old infants, including 10 maltreated infants, 18 nonmaltreated high-risk infants, and 28 matched low-income controls, were videotaped in naturalistic settings at home with their mothers for 40 min and were observed 2 weeks later in the Ainsworth Strange Situation. Maltreating mothers were rated higher than nonmaltreating mothers on covertly hostile and interfering behaviors toward their infants at home. Maltreated infants were more avoidant of their mothers in the Strange Situation than nonmaltreated infants. Correlations between maternal behaviors at home and infant behaviors in the Strange Situation revealed that mothers whose infants displayed resistant behavior on reunion were rated at home as less verbally communicative and mothers whose infants displayed avoidant behavior on reunion were rated at home as more covertly hostile. Infants showing mixed avoidance and resistance were more likely to have extremely uncommunicative mothers than were infants who showed avoidance alone. Use of the behavioral rating scales for avoidance and resistance produced clearer findings than use of the final attachment classifications. Reasons for the discrepancies between analyses of classifications and analyses of behavior ratings were identified. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relationships between marital distress and child behavior problems, maternal personal adjustment, maternal personality, and maternal parenting behavior.

Examined the relationship of marital adjustment to maternal personal adjustment, maternal personality, maternal perception of child adjustment, maternal parenting behavior, and child behavior using 20 maritally distressed and 20 maritally nondistressed mothers and their children (aged 3–7 yrs). Ss were given a battery of tests that included the Beck Depression Inventory, the Trait form of the State-Trait Anxiety Inventory, and the Personality Research Form—Form A. Results indicate that, compared to mothers in the maritally nondistressed group, mothers in the distressed group perceived themselves as significantly more anxious and depressed and perceived their children as having significantly more behavior problems, particularly in the area of undercontrol. There were no differences between the groups with respect to maternal personality. Maritally distressed mothers showed less appropriate parenting behavior than did nondistressed mothers and the children of maritally distressed mothers were more deviant than were children of nondistressed mothers.

Emotional exchange in mother-child dyads: Stability, mutual influence, and associations with maternal depression and child problem behavior.

This study examined the stability of the child and maternal affective expression and maternal responsiveness and the mutual influence of child and maternal expression of emotion. The authors tested whether maternal depression and child problem behavior were associated with the pattern of emotional exchange within the mother-child dyads. The sample consisted of 69 mother-child dyads (children aged 2-5 years), with 32 of the mothers having childhood-onset depression. Mothers were mostly stable in their affective expression (positive and negative) and responsiveness, whereas children were only stable in positive expression. Within the dyads, mothers seemed to play a more important role in regulating children's later emotional expression. Maternal depression was associated with concurrent maternal responsiveness and their reduced positive expression over time. Results are discussed in relation to the differential function of parental general positivity and responsiveness and the interpersonal transmission of emotional problems.

Trajectories of maternal depressive symptoms, maternal sensitivity, and children's functioning at school entry.

Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the authors modeled trajectories of maternal depressive symptoms from infant age 1 month to 7 years. The authors identified 6 trajectories of maternal depressive symptoms: high-chronic, moderate-increasing, high-decreasing, intermittent, moderate-stable, and low-stable. Women on these depression trajectories varied in sociodemographic risk and in changes in observed maternal sensitivity over time. Maternal sensitivity was generally higher and increased when depressive symptoms were low; sensitivity was lower and decreased when depressive symptoms were either high or increasing. Child outcomes at 1st grade were examined by trajectory group. The authors discuss the complexity of disentangling maternal symptoms from maternal sensitivity and sociodemographic risk when predicting children's functioning.

Parental perceptions of child behavior problems, parenting self-esteem, and mothers' reported stress in younger and older hyperactive and normal children.

40 parents of younger and older hyperactives (Hs; aged 5 yrs 1 mo and 8 yrs 4 mo, respectively) and 51 parents of age-matched normal controls completed measures of hyperactivity and child behavior, parenting self-esteem (PSE), and parenting stress. PSE was lower in parents of Hs than in parents of controls. Self-esteem related to skill/knowledge as a parent was age related, with parents of older Hs reporting the lowest levels; self-esteem related to valuing/comfort in the parenting role was not related to the child's age. Mothers of Hs, especially younger ones, reported markedly higher levels of stress associated with both child characteristics and their own feelings, such as depression, self-blame, and social isolation. Consistent inverse relationships were found between PSE and perceptions of child problems, whereas ratings of child disturbance and maternal stress were positively correlated. Findings are discussed in terms of the social contexts surrounding hyperactivity and the need for multidimensional assessments and interventions in families of Hs.

Origins of generalized control expectancies: reported child stress and observed maternal control and warmth

The relations among reported stressful events, maternal control and warmth, and children's locus of control of reinforcement were investigated. Fifty-five 2nd-grade. U.S. children completed the Children's Nowicki-Strickland Internal-External Locus of Control Scale, and their mothers completed a modified form of Coddington's Life Events Scale for their child. Mother and child also were videotaped while they worked together on three puzzles. The results indicated that, compared with children with external control expectancies, children with internal control expectancies had experienced less stress in their lives. Furthermore, when observed interacting with their children, mothers of children with internal control expectancies were rated as displaying less control and more warmth than mothers of children with external control expectancies. The findings generally are consistent with predictions based on Rotter's social learning theory for the development of individual differences in generalized control expectancies.     

Screening of child behavior problems for prevention programs at school entry.

Targeted programs designed to prevent conduct problems in childhood and adolescence rely on screening systems to identify high-risk individuals. This study examines the proximal usefulness of a multiple-gating approach to screening, using teacher and parent ratings in a 2-step procedure with a sample of 382 kindergarten children. The study explored differences in the accuracy of the 2 steps of screening information and whether parents' reports of parenting practices augments the prediction of negative outcomes. The 2-step screening system was found to effectively predict negative behavior outcomes over 1 year later, although some false-positive and false-negative predictions were evident. The Parenting Practices Screen did not substantially add to prediction accuracy. The discussion emphasizes the potential contributions and problems of using screening measures.

Frightening maternal behavior linking unresolved loss and disorganized infant attachment.

Main and Hesse's (1990) model in which frightening (threatening, frightened, or dissociated) parental behavior explains why infants of parents with unresolved loss develop disorganized attachment relationships was tested. Unresolved loss using the Adult Attachment Interview in a nonclinical middle-class sample of 85 mothers who had experienced the loss of someone important was assessed. Disorganized attachment was examined in the Strange Situation. Parental behavior was recorded during 2 2-hr home visits. The model applied to mothers with currently insecure attachment representations. Secure mothers with unresolved loss displayed less frightening behavior than other mothers, and unresolved loss in secure mothers did not predict disorganized attachment of their infants. Frightening behavior predicted infant disorganized attachment irrespective of maternal security. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children conceived by gamete donation: Psychological adjustment and mother-child relationships at age 7.

An increasing number of babies are being born using donated sperm, where the child lacks a genetic link to the father, or donated eggs, where the child lacks a genetic link to the mother. This study examined the impact of telling children about their donor conception on mother-child relationships and children's psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction, and child adjustment were administered to 32 egg donation, 36 donor insemination, and 54 natural conception families with a 7-year-old child. Although no differences were found for maternal negativity or child adjustment, mothers in nondisclosing gamete donation families showed less positive interaction than mothers in natural conception families, suggesting that families may benefit from openness about the child's genetic origins.

Subjective probability of accident and apprehension in relation to self-other bias, age, and reported behavior

Responses from over 900 male drivers were examined on items measuring the subjective probability of two adverse driving scenarios (accident and apprehension) for a number of speeding and drink-driving-related events. The items were constructed to focus on self versus average referent driver comparisons. Respondents were categorised into "offenders" and "non-offenders" according to their reported behaviour concerning speeding and drink-driving. The data were analysed using repeated measures analysis of variance. The results indicated that both accident and apprehension are seen as less probable when self is the reference compared to the average driver. There was evidence to suggest that this self-favouring bias did vary over presented scenarios. It was suggested that such perceptions may vary in relation to the perceived influence of driver skill within scenarios. Weak age effects were found, but it was concluded that, generally, self-favouring biases were common across all age groups. Concerning the offender/nonoffender classification, the results indicated that speeders and drink-drivers generally perceived the probability of apprehension and accident as being lower than did the nonoffender groups. There was no evidence to suggest that self-average driver biases were associated with offender/nonoffender grouping.     

Correlates of marital behavior at 6 months postpartum

This study was aimed at characterizing the level of specificity of the human newborn's response to an odor experienced in utero. Three groups of breast-fed infants and 3 groups of bottle-fed infants were examined on Postnatal Day 3 for their differential head-turning response when exposed to paired-choice tests contrasting the odors of either familiar (f) amniotic fluid (AF) or nonfamiliar (nf) AF or either of these AF odors and a control (C) stimulus. In fAF versus nfAF tests, the infants oriented preferentially to the odor of fAF, regardless of their feeding regimen (i.e., of their postnatal reexposure to AF-like cues in maternal milk). The fAF or nfAF versus C tests showed that this response pattern was caused by a true positive orientation toward fAF and not by avoidance from nfAF odor. This highly selective neonatal response to fAF odor is consistent with the hypothesis that the human fetus can detect and store the unique chemosensory information available in the prenatal environment and that this information becomes coupled with positive control of behavior.     

Maternal attachment representations, maternal sensitivity, and the infant–mother attachment relationship.

The role of maternal sensitivity as a mediator accounting for the robust association between maternal attachment representations and the quality of the infant-mother attachment relationship was examined. Sixty mother-infant dyads were observed at home and in the Strange Situation at 13 months, and mothers participated in the Adult Attachment Interview (AAI) within the next 6 months. A strong association was found between AAI and Strange Situation classifications. and autonomous mothers were more sensitive at home than were nonautonomous mothers. Mothers in secure relationships were more sensitive at home than mothers in nonsecure relationships. Likewise, infants in secure relationships were more secure as assessed by the Waters' Attachment Q sort than infants in nonsecure relationships. A test of the mediational model revealed that maternal sensitivity accounted for 17% of the relation between AAI and Strange Situation classifications.

Labels and explanations in mother-child emotion talk: age and gender differentiation

Specific proteins of the apolipoprotein serum amyloid (apoSAA) family that are synthesized in large quantities during the acute, early phase of inflammation can serve as the proteinaceous precursors for amyloid fibrils. To model fibrillogenesis in such inflammatory diseases, we have used electron microscopy and X-ray diffraction to examine the structures formed by synthetic peptides corresponding in sequence to the 11 amino-terminal amino acids of murine apoSAA1, apoSAAcej, and apoSAA2 and to the 15 amino-terminal amino acids of apoSAA2. This region is reported to be the major fibrillogenic determinant of apoSAA isoforms. Both in 1 mM Tris buffer and in 35% acetonitrile, 0.1% trifluoracetic acid (ACN/TFA), all of the peptides formed macromolecular assemblies consisting of twisted, approximately 40- to 60-A-thick ribbons, which varied in width from around 40-70 A (for 11-mer apoSAA2 in Tris) up to 900 A (for the other peptides). X-ray diffraction patterns recorded from lyophilized peptides, vapor-hydrated samples, and solubilized/dried samples showed hydrogen bonding and intersheet reflections typical of a beta-pleated sheet conformation. The coherent lengths measured from the breadths of the X-ray reflections indicated that with hydration the growth of the assemblies in the intersheet stacking direction was comparable to that in the hydrogen-bonding direction, and analysis of oriented samples showed that the beta-strands were oriented perpendicular to both the long axis and the face of the assemblies. These X-ray results are consistent with the ribbon- or plate-like morphology of the individual aggregates and emphasize the polymorphic nature of amyloidogenic peptides. Our findings demonstrate that X-ray diffraction measurements on vapor-hydrated or solubilized/dried versus lyophilized, amyloidogenic peptides are a good indicator of their fibrillogenic potential. For example, from the highest to the lowest potential, the peptides examined here were ranked as: Abeta1-28 > Abeta1-40 > apoSAA1 approximately apoSAAcej > apoSAA2 > Abeta17-42. Experiments in which the three different 11-mer apoSAA isoforms were solubilized in ACN/TFA and then combined as binary mixtures showed that the ribbon morphology was not affected but that the extent of hydrogen bonding in the assemblies was substantially reduced. Our observations on the in vitro assembly of apoSAA analogs emphasize that amyloid fibril formation and morphology depend on primary sequence, length of polypeptide chain, the presence of additional fibrillogenic polypeptides, and solvent conditions.     

Chronic malnutrition and child behavior: Effects of early caloric supplementation on social and emotional functioning at school age.

138 chronically malnourished Ss (aged 6–8 yrs) were observed in social interactions in 6-S groups and administered a battery of cognitive tests, including the Bender-Gestalt. Independent variables were measures of maternal caloric supplementation (CAS) during pregnancy, and child CAS from birth to 2 yrs, and from age 2 to 4. High CAS from birth to 2 yrs predicted high levels of social involvement, both happy and angry affect, and moderate activity level at school age. Low CAS was associated with passivity, dependency on adults, and anxious behavior. These relationships were significant when socioeconomic status and maternal CAS were controlled. Cognitive measures were not strongly predicted by supplement intake. Results indicate the importance of adequate energy intake in infancy for later social–emotional development.

Childhood asthma: mothers' affective attitude, mother-child interaction and children's compliance with medical requirements

Maternal critical attitude (CA) and negative mother-child verbal interaction in families with an asthmatic child and in controls were investigated in the present study. Twenty-eight children with bronchial asthma (6-13 yr) and 23 healthy children with their mothers participated in the project. Mothers were asked to describe their child (Five Minute Speech Sample; FMSS). Mother and child were then asked to discuss a mutual problem (Problem Discussion; PD). Tape recordings were taken. The mothers' responses during the FMSS were used to assess CA. Negative verbal behavior during PD was coded by means of a reliable coding system for dyadic interaction. Significantly more mothers of the asthmatic children than of the controls showed CA during the FMSS. Mothers of the asthmatic children made significantly more critical remarks and offered more negative solutions during the PD. Within the asthma group mothers who made more critical remarks had to make more effort to have their child comply with the medical requirements. Additionally, mothers showing a higher total amount of negative verbal behavior had children with rather high IgE levels. There was no systematic difference between children having CA mothers with high vs low face-to-face contact.     

Attachment at school age and academic performance.

The association between attachment and school-related cognitive functioning was longitudinally examined for a French Canadian sample of 108 school-age children. The affective quality of mother-child interaction patterns, child cognitive engagement, and quality of child attachment to mother were evaluated during a laboratory visit that included a separation-reunion procedure occurring when the children were approximately 6 years of age. Children's mastery motivation and academic performance were assessed 2 years later (at age 8). Analyses indicated that secure children had higher scores than their insecure peers on communication, cognitive engagement, and mastery motivation. Controlling children were at greatest risk for school underachievement, with the poorest performance on all measures except mastery motivation. Avoidant and ambivalent children were lowest on mastery motivation. Results of mediational analyses support the salience of mother–child interactional processes and child cognitive engagement at school age in explaining relations between attachment and cognitive functioning in school.

Size at birth, maternal nutritional status in pregnancy, and blood pressure at age 17: population based analysis

OBJECTIVE: To assess the effect of size at birth, maternal nutrition, and body mass index on blood pressure in late adolescence. DESIGN: Population based analysis of birth weight corrected for gestational age, mother's weight before pregnancy and weight gain in pregnancy, obtained from the Jerusalem perinatal study, and blood pressure and body mass index at age 17, available from military draft records. SETTING: Jerusalem, Israel. SUBJECTS: 10,883 subjects (6684 men and 4199 women) born in Jerusalem during 1974-6 and subsequently drafted to the army. MAIN OUTCOME MEASURES: Systolic and diastolic blood pressures measured at age 17 and their correlation with birth weight, size at birth, mother's body mass index and weight gain during pregnancy, and height and weight at age 17. RESULTS: Systolic and diastolic blood pressures were significantly and positively correlated with body weight, height, body mass index at age 17, and with mother's body weight and body mass index before pregnancy, but not with birth weight or mother's weight gain in pregnancy. CONCLUSION: Variables reflecting poor intrauterine nutrition, including low maternal body mass index before pregnancy, poor maternal weight gain in pregnancy, and being born small for gestational age, were not associated with a higher blood pressure in late adolescence.     

Observed sibling interaction: links with the marital and the mother-child relationship

The study examines whether the link between the marital relationship and sibling interaction is direct or mediated by the mother-child relationship. Seventy-three same-sex siblings pairs aged 3 years 6 months to 8 years 6 months were observed during free play. Mothers completed questionnaires assessing marital functioning and their relationship with their 2 children. Results indicated that older siblings' negative behavior is linked with negative dimensions of the marital and the mother-child relationship, whereas younger siblings' negative behavior is linked with the mother-child and the differential mother-child relationship. Siblings; positive behavior, although linked with spacing, is not linked with positive dimensions of family interaction. Most important, the linkage between negative marital relations and older siblings; negative behavior was found to be mediated by maternal power assertion, thereby supporting the indirect model of negative family interaction.
