The relationship of maternal perception and maternal behavior: a study of normal mothers and their infants.

Normal mothers of nine-month-olds generally perceived their infants' behavior accurately. However, where maternal perceptual distortions did occur, they were associated with less maternal responsiveness and greater interference. These correlated with the mothers' anxiety level and with infant sleep problems. Maternal expectations thus seemed to be translated into specific maternal behavior which may be of significance in the child's psychosocial adjustment.

Emotional regulation and its impact on development in extremely low birth weight infants.

The purposes of this study were to compare the Bayley Scales of Infant Development (BSID-II) scores at 8 and 18-22 months adjusted age of a cohort of 47 extremely low birth weight infants and to determine whether there was an association between changes in test scores and infant behavior as measured by the Behavioral Rating Scale of the BSID-II at 18-22 months adjusted age. Psychomotor Developmental Index scores did not differ between the two testing points (p = .17), whereas the Mental Developmental Index (MDI) scores dropped significantly (p = .006). Emotional regulation and low household income were both significantly associated with changes in MDI scores (p = .001 and p = .002, respectively). After adjusting for household income, the association between emotional regulation and changes in MDI scores remained significant (p = .02). Results suggest that infant behavioral characteristics, as well as family socioeconomic status, can adversely affect developmental outcome at 18-22 months adjusted age.

Infant wariness toward strangers reconsidered: infants' and mothers' reactions to unfamiliar persons.

In this study, the interpretation of infants' responses to approaching strangers as "wariness" or "fear" was questioned by comparing infants' behaviors toward strangers with adults' behaviours toward strangers. 24 8-month-old infants and their mothers were observed in a standard laboratory situation. Both infants and mothers were approached by female strangers with a fast, 12-sec approach and a slow, 40-sec approach. Mothers' and infants' behaviors were coded at 4 distances during each approach. Behaviors coded were smile, alert face, quizzical look, frown, looks at mother/infant, looks at stranger, and averts gaze. Mothers showed significantly more behaviors typically labeled "wary" than did infants, particularly as the proximity of the stranger increased. These findings suggest that wary responses toward strangers are not unique to infants and may be more characteristic of the situation than of the developmental level of the individual.

[Attention behavior of infants and modulation of maternal language].

Language spoken to infants has several peculiarities that are also found in other cultures. In this study we have examined the specific relationships between some infant's behaviours and the prosodic modulations of maternal speech in a face to face interaction. 14 mothers with their four month-old infant were observed in a laboratory setting in order to obtain a corpus of 2100 maternal words. There is a variation of maternal speech prosody that depends upon the attentional behaviours of the infant. When the infant is interacting (the gaze is directed towards the mother with a neutral or positive expression, joint gaze), the mother has a tendency to produce longer utterances with a more variable fundamental frequency than that observed when the infant is not interacting (looking elsewhere or alternating). There is also a larger occurrence of complex and bell-shaped curves during the infant's positive and joint gazes. The infant appears to be an active partner in mother-infant verbal exchange.

Implications of a dynamical systems approach to understanding infant kicking behavior.

Implications of the dynamical systems approach to understanding movement dysfunction in infants are discussed. Traditional theories of motor development attribute changes in movement to the hierarchical maturation of the central nervous system. The dynamical systems approach emphasizes that movement self-organizes as the result of the interaction of the participating subsystems in developmental and real time. In this article, I discuss, from the theoretical perspective of the dynamical systems approach, the organization of leg movements in low- and high-risk preterm and full-term infants, developmental changes in movement in low-risk preterm infants from 34 weeks' gestational age to 40 weeks' postgestational age, and differences in movement between low-risk preterm infants at 40 weeks' postgestational age and full-term infants. Preliminary data on high-risk preterm infants are presented. Based on these data, the necessity to review and reinterpret traditional concepts of motor development is explored. Suggestions are offered and questions posed on how the dynamical systems perspective may influence the practice of physical therapy in the evaluation, and treatment of infants at risk for movement dysfunction.

Selective information use and perseveration in the search behavior of infants and young children.

Two experiments examined the early development of selective information use in search. The first experiment tested 9- and 16-month-olds on a modification of Piaget's Stage IV object permanence task. It examined infants' use of information from previous experiences with an object (prior information) and from the most recent hiding (current information) to locate a hidden object. In the second experiment, 2-, 2 1/2-, and 4-year-old children received these same sources of information along with new forms of prior and current information: information about the typical locations of objects (location specificity) and verbal information. No systematic perseveration was observed at 9 months, although previous findings related to perseveration were replicated. Perseveration was found at 16 months, but there was also evidence of selectivity at that age. When errors occurred, they tended to be to the prior location, but they were infrequent in comparison to correct searches at the current location. The preschoolers, while continuing to show perseveration, were more consistently selective than the infants. They also showed considerable generality in extending their selectivity to new sources of information.

Newborn predictors of infant irritability.

OBJECTIVE: To identify newborn infant behaviors that may predict infant irritability, commonly referred to as colic. DESIGN: A prospective, correlational design, with data collection occurring the first 4 days of life and again at 1 month of age. SETTING: This study was conducted in a private hospital in a large metropolitan city in the Midwest. PARTICIPANTS: Sixty infants who were at low risk and full term and whose weight was appropriate for gestational age were recruited during their postpartum hospital stay. Infants with congenital anomalies, signs of illness, or high-risk factors were excluded from the study. MAIN OUTCOME MEASURES: During infants' 1-4-day hospital stays, their crying was assessed and reported by the nurses, and a Neonatal Behavioral Assessment Scale was completed on each infant. At 1 month of age, irritability was measured using the Fussiness Rating Scale. RESULTS: Only two components of the Neonatal Behavioral Assessment Scale were related to development of colic or infant irritability at 1 month of age. These were the cluster of variables representing motor activity and the Neonatal Behavioral Assessment Scale supplemental item measuring the persistence necessary on the part of the examiner to get the infant to attend to stimuli presented. The infants who were classified by parents as irritable at 1 month of age were more active and more attentive to stimuli in the first few days of life. CONCLUSIONS: Of interest was that the newborn nursery nurses cry ratings were not related to the later development of colic in these infants. Active infants who are sensitive to stimuli may be predisposed to infant irritability; however, further work is needed to understand the relationships of these infant characteristics to the human interactions and physical environments they encounter

Actigraphy correctly predicts sleep behavior in infants who are younger than six months, when compared with polysomnography.

Actigraphy has been widely used in adults and children. In infants, validation of actigraphy has typically used a comparison with behaviorally determined sleep state classification rather than polysomnography (PSG). This study validated actigraphy against PSG for determining sleep and waking states in infants who were younger than 6 mo. Twenty-two healthy infants, 13 term and 9 preterm, were studied at three different matched postconceptional ages. Actigraph data were compared with PSG recordings in 1-min epochs. Agreement rate (AR), predictive value for sleep, predictive value for wake, sensitivity. and specificity were calculated and compared between activity thresholds and across ages with two-way ANOVA for repeated measures. Thirty-two validation studies were analyzed. Overall AR with PSG of 93.7 +/- 1.3 and 91.6 +/- 1.8 were obtained at 2-4 wk and 5-6 mo, respectively, at the low activity threshold setting, whereas the auto activity threshold gave the best agreement with PSG at 2-4 mo (AR 89.3 +/- 1.3%). Sensitivity values of 96.2 +/- 1.1% at 2-4 wk, 91.2 +/- 1.5% at 2-4 mo, and 94.0 +/- 1.9% were obtained at these same settings. There was no difference across ages in AR or sensitivity. PVW and specificity values were low in this study. We conclude that actigraphy is a valid method for monitoring sleep in infants who are younger than 6 mo.

Maternal ratings of infant intensity and distractibility: relationship with crying duration in the second month of life.

OBJECTIVE: To investigate the relationship between infant temperament characteristics assessed at 4 weeks of age and the duration of infant crying and fussing during the second month of life. DESIGN: Families were enrolled in this prospective study during prenatal classes, and 60 infants completed the study. Temperament was assessed when the infant was 4 weeks of age using the Early Infancy Temperament Questionnaire, and crying and fussing was assessed on 16 days during the second month of life using a parent-completed infant behavior diary. RESULTS: Ratings of the total duration of infant crying and fussing correlated significantly with the sum score on the temperament questionnaire (r = 0.36; P =.005). A longer duration of crying and fussing was associated with infants with high intensity (r = 0.43; P =.001) and low distractibility (r = 0.37; P =.003). CONCLUSIONS: The finding that mothers rating their infants as having high intensity and low distractibility is associated with increased crying duration supports a growing body of literature suggesting that infants with high levels of crying are more reactive to sensory stimuli and harder to soothe than those who cry less. Physicians counseling parents of infants with persistent crying should recognize the infant characteristics associated with increased crying.

Group-based parent-training programmes for improving emotional and behavioural adjustment in 0-3 year old children.

BACKGROUND: Mental health problems in children are common. Research suggests that parenting has an important role to play in helping children to become well adjusted adults, and that the first few months and years of a child's life are especially important in establishing patterns of emotional, cognitive and social functioning which will in turn influence the child's future development and in particular, their mental health. Parenting programmes may therefore have a role to play in improving the mental health of infants and toddlers. OBJECTIVES: The objectives of this review are as follows: a) To establish whether group-based parenting programmes are effective in improving the mental health of children less than three years of age b) To assess the role of parenting programmes in the primary prevention of mental health problems SEARCH STRATEGY: A range of biomedical and social science databases were searched including MEDLINE, EMBASE, CINAHL, PsychLIT, Sociofile, Social Science Citation Index, ASSIA, the Cochrane Library including SPECTR, CENTRAL, National Research Register (NRR) and ERIC. SELECTION CRITERIA: Only randomised controlled trials were included and studies had to include at least one standardised instrument measuring some aspect of infant mental health. DATA COLLECTION AND ANALYSIS: The treatment effect for each outcome in each study was standardised by dividing the mean difference in post-intervention scores for the intervention and treatment group, by the pooled standard deviation, to obtain an effect size. The results for each outcome in each study have been presented with 95% confidence intervals. Where appropriate the results have been combined in a meta-analysis using a random effect model. MAIN RESULTS: A total of five studies were included in the review. The 5 included studies provided a total of 36 assessments of infant and toddler mental health including emotional and behavioural adjustment, and sleep patterns. All of the results apart from 6 showed positive findings favouring the intervention group. While some of findings were non-significant, most of the effect sizes were large and the wide confidence intervals crossing the zero that were obtained in a number of the studies, were very probably due to small sample sizes. There was sufficient data from four studies to combine the results in a meta-analysis. The results of the meta-analysis show a significant difference in children's emotional and behavioural adjustment favouring the intervention group. Overall, the limited follow-up data provide equivocal evidence concerning the maintenance of these effects over time. REVIEWER'S CONCLUSIONS: The results of this review suggest that parenting programmes can be effective in improving the mental health of infants and toddlers. There is, however, insufficient evidence to reach any firm conclusions regarding the role that such programmes might play in the primary prevention of mental health problems. Furthermore, there is insufficient evidence to know whether the short-term benefit of these programmes is maintained over time, and further research is required.

Infant and maternal behavior moderate reactivity to novelty to predict anxious behavior at 2.5 years.

The degree to which infant regulatory behaviors, together with infant reactivity to novelty, predicted anxious behavior at 2.5 years, and the moderating effect of maternal behavior were tested. Sixty-four low-risk mothers and infants participated. Mothers rated infant negative reactivity and anxious behavior; infant and maternal behaviors were observed at 6 months postpartum. Based on results of hierarchical, multiple regressions, infant regulatory behaviors (i.e., attention control, withdrawal) moderated associations between reactivity to novelty and later anxious behavior, but predictions depended also on maternal behavior. High reactivity to novelty, in conjunction with withdrawal and with poor attention control, predicted anxious behavior only when mothers were less engaged or less sensitive, suggesting that maternal behavior alters developmental trajectories associated with infant temperament.

Early intervention using Brazelton training with middle-class mothers and fathers of newborns.

The purpose of this study was to test the effectiveness of the Brazelton exam as a parent education tool for mothers and fathers. 42 middle-class families with firstborn, healthy, full-term infants were randomly assigned to one of three groups: father treatment, mother treatment, and control. The target parents in the treatment groups were taught to perform the Brazelton exam on their own infant, with attention being drawn to the infant's most positive interactive and physical abilities. Questionnaire and observational data were collected in the hospital and at 4 weeks postpartum. These included measures of knowledge of infant behavior, confidence in parenting ability, satisfaction with the infant, and behavior with the infant. The results showed that treatment parents scored higher in knowledge about infants, at both the early and the 4-week periods. Also, treatment fathers were more involved in caretaking with their infants at 4 weeks than were control fathers. More modest treatment effects were shown for confidence and satisfaction measures. No behavioral treatment effects were found during a 10-min observation of parent-infant interaction.

[Mothers' behavior regarding infant sleep position: effects of the last public campaign to prevent sudden infant death syndrome].

BACKGROUND: To define infant care practices in maternity units and those subsequently adopted at home. Using these data, we evaluated the acceptance and application of recommendations issued by the previous public education campaign on infant sleeping position as related to sudden infant death syndrome. PATIENTS AND METHODS: A survey was carried out in two maternity units (Port-Royal and Créteil) and in one pediatric consultation unit (affiliated with Port-Royal maternity). RESULTS: The mixed position (side or back) is used equally with, respectively, 47% at Port-Royal and 45% at Créteil. The supine sleeping position (French public health recommendations) is used by 12% of the mothers at Port-Royal and by 40% at Créteil. It appears that hospital nurseries play an important role in determining the mother's preference for the sleeping position (64% at Port-Royal and 54% at Créteil), but it does not adequately explain all mothers' responses. However, as the infants mature (> two months old), the more spontaneously they changed their sleeping position. All the infants placed in a side sleeping position moved to a supine sleeping position during the night. Upon awakening, infants were found mostly in the supine position (in contrast to the national public education campaign). CONCLUSION: Our results show that mothers and hospital nurseries were distressed in terms of ensuring the supine sleeping position of the infant. New choices of sleeping positions were initiated by mothers. For example, they used the side position after feedings essentially in the case of reflux or during the daytime. The supine position was used when the mothers were assured that any problems had been avoided or only during the night.

Maternal representations of the infant: associations with infant response to the still face.

Mothers' representations of their infants may influence early development of emotional self-regulation. This study examined the associations between characteristics of mothers' (N = 100) narratives about their 7-month-old infants, maternal depression, and their infants' affect regulation during the Still Face procedure. Findings showed that (1) mothers' representations were linked with individual differences in their infants' behavior across the Still Face procedure, (2) the association between mothers' representations and their infants' behavior was mediated by parenting behavior, and (3) mothers' representations explained unique variance in their infants' affect regulation beyond the contribution of maternal depression. Although infants' displays of positive affect diminished while mothers held a still face, only infants of mothers in the balanced representation category returned to high levels of positive affect upon resuming interaction. These findings highlight the role of maternal representations in the process by which dyads repair temporary disruptions in interaction, as well as individual differences in infants' and mothers' responses to the Still Face.

Down's syndrome and infant gaze. Gaze behavior of Down's syndrome and nondelayed infants in interactions with their mothers.

The study reported here compared the gaze behavior of infants with Down syndrome (DS) and nondelayed infants during interactions with their mothers. The subjects were 10 DS infants and 11 nondelayed infants. Five of the DS infants and 6 of the nondelayed infants were 4 months old; the rest were 9 months old. The results support the expectation that infants with DS gazed at their mothers longer than did nondelayed infants during face-to-face play, and also indicate that all the infants visually attended to their mothers less at 9 months than at 4 months of age. It is conjectured that the increased gaze of the infants with DS may well facilitate attachment in the 1st year of life.

A new method to quantitatively describe pain behavior in infants.

Photogrammetric techniques were used to record the responses of 10 newborn infants to heelstick procedures at 4 hours of age. The responses consisted of an immediate withdrawal of both the affected and unaffected leg, followed by facial grimacing and crying. The median latency of withdrawal in response to the first heelstick was 0.3 seconds for the unaffected and 0.4 seconds for the affected leg, respectively. The median latency following a second heelstick was 0.2 seconds for both legs. The median latency of cry was 1.8 seconds following the first heelstick and 1.6 seconds following the second heelstick. Other quantitative parameters of the response, velocity of first affected leg movements, number of leg movements, and number of movements directed toward the stimulus, were also measured. This pilot study demonstrated a method by which quantitative data regarding pain responses in infants can be obtained and evaluated.
