As part of a longitudinal study of offspring born to substance abusers, we videotaped 17 methadone-exposed and 23 comparison 4-month-old infants interacting with their mothers. Using a scale we developed, we rated communicative functioning in dyadic interaction and related mothers' interactive performance to their psychological and psychosocial resources and infants' interactive performance to their motor functioning as assessed on the Bayley Infant Behavior Record. We found, cutting across drug groups, that mothers who performed poorly on interaction were likely to have poor maternal resources and that infants showing poor communicative functioning were likely to show problematic motor functioning--namely, greater tension and poorer coordination relative to activity level; it was the opposite for mothers or infants who communicated well. Methadone was only one among several risk factors affecting interaction.  相似文献

To test the efficacy of temporally patterned kinesthetic and auditory stimulation for promoting development of infants born prior to term, 88 preterm infants, below 35 weeks gestation, were assigned to 1 of 4 experimental or control groups. Control subjects received regular hospital care; fixed interval subjects received 15 min of rocking/heartbeat stimulation each hour; self-activating subjects received 15 min rocking/heartbeat when inactive for 90 sec, but only for 1 stimulation period per hour. Assessments included measures of neurological functioning, sleep-wake activity, mother-infant interaction, and mental and motor development at 8 and 24 months. All experimental infants, compared to controls, showed decreased rates of activity while in the hospital, fewer abnormal reflexes, and better orienting responses. At 24 months, experimental infants scored significantly higher on the Mental Development Index of the Bayley Scales. Few differences were found in parent-infant interaction patterns. The results indicate that both temporal patterning and contingent responsiveness in the preterm infant's early environment contribute positively to some aspects of the development of such infants.  相似文献

This paper outlines the Parental Stress Center (PSC) residential treatment program and its evaluation study, specifically focusing on the developmental status of infants in treatment. The Bayley scores for mental/motor development are given for a subgroup of 20 deprived infants admitted to the residential center and for two matched groups. One comparison group consisted of similarly deprived infants, the other of normal infants. The groups, tested three times, showed few differences either among the three groups at each time period or within each group over the three time periods. The most significant between-group difference was in motor scores at time 2, with both PSC infants and problem comparison infants scoring significantly below the normal comparison infants. The decline of motor scores of the PSC infants was probably attributable to the physical restrictions of the nursery. By the final testing at age 1, these scores had improved, and again there were no group differences. The results indicate that despite the use of multiple caregivers, the deprived infants admitted to residential care kept pace with similar babies in other treatment modalities. The overall high scores when compared to other research data indicate the decided worth of early intervention.  相似文献

Developmental psychophysiologists have long been interested in a means for evaluating infants at risk for cognitive disabilities. The current research addressed the utility of a noninvasive measure of cardiac vagal tone in predicting developmental outcome. At 40 weeks conceptional age, 3 min of resting EKG were recorded from 80 infants. Four groups of infants were evaluated: prematures who had no medical complications in the postnatal period; prematures who experienced respiratory distress syndrome during the postnatal period; term infants who experienced birth asphyxia during labor and/or postdelivery; and healthy term infants. The mental scale of the Bayley Scales of Mental Development was administered at 8 and 12 months conceptional age. Heart period data were analyzed to derive mean heart period, heart period variability, and estimates of vagal tone for each subject. Analyses of the relationship between the heart period variables and 8- and 12-month outcome (i.e., Bayley Scales) indicated that infants with high vagal tone at 40 weeks conceptional age always had positive developmental outcome at both eight and 12 months of age. Infants with low vagal tone had varied outcomes. Measures of medical complications and other measures of heart period variability were not related to developmental outcome. The results suggest that measurement of cardiac vagal tone may provide an important means for assessing risk in birth stressed populations.  相似文献

A close association between affective expression and cognitive development was demonstrated in a longitudinal study of 14 Down's syndrome infants. It was found that the Down's syndrome infants laughed to groups of stimulus items in the same order as did previous samples of normal infants. Although the process was delayed by several months, the retarded babies too laughed first at physically intrusive items and only later to items calling for greater cognitive sophistication. In addition, cognitive developmental status, assessed by the Bayley and Uzgiris-Hunt scales, paralleled and was predicted by the level of affective development. Predictive and concurrent correlations between Bayley mental scores and various indices of affectivity ranged from .68 to .92. There was striking individual consistency across affective, mental, and motor measures, suggesting the organized nature of retarded development. Finally, since Down's syndrome infants frequently smiled under conditions when normal babies would laugh, a role for tension production, in addition to cognitive factors, was suggested in accounting for the behavior of these infants.  相似文献

31 infants at high social risk due to the combined effects of poverty, maternal depression, and caretaking inadequacy were assigned to weekly home-visiting services. At 18 months infant age, the home-visited infants were compared with 2 groups of socioeconomically similar unserved infants on measures of infant development, infant attachment, mother-infant interaction, maternal depression, and maternal social contacts. Home-visited infants of depressed mothers outperformed unserved infants of depressed mothers by an average of 10 points on the Bayley Mental Scale and were twice as likely to be classified as securely attached, with unserved high-risk infants showing a high rate of insecure-disorganized attachments. Duration of services was positively correlated with maternal involvement at 12 months. Results of the study point both to the negative developmental consequences associated with severe social risk conditions and to the buffering effects of developmentally oriented home-visiting services for infants at greatest social risk.  相似文献

46 graduate students who had indicated that their major interest was teaching were compared with 47 graduate students who had indicated that their major interest was counseling. All subjects were given five scales as part of their course work in educational tests and measurements. These scales yielded 32 subtests on which comparisons between the groups were made. The groups differed on six of the subtests. Three of the variables on which the groups differed were interest measures. A further comparison was made between the counselor candidates who had a practicum and those who had not. Little difference was found between these groups on the variables investigated.  相似文献

A number of preterms who had participated in a study of visual recognition memory when they were 6 months of age were seen at older ages to assess the predictive validity of the early visual measures for cognitive outcome. The Bayley scales were administered at 6, 12, and 24 months, the Stanford-Binet at 34 and 40 months, and the WISC-R at 6 years. Novelty scores, which reflect the relative amount of time infants look at new compared to familiar stimuli, constituted the measure of infant visual processing. These scores, obtained by averaging over performance on the 3 or 4 problems administered at 6 months of age, were consistently and significantly related to cognitive measures from 24 months to 6 years, with correlations ranging from r = .53 to r = .66. Parental education, which was unrelated to novelty scores, bore a strong relationship to outcome beginning at 24 months. Although both measures contributed uniquely to the variance in cognitive outcome at 24 months and 6 years, visual novelty scores made a stronger contribution than did parental education. Neither 6- nor 12-month Bayley scores, nor various perinatal variables, were related to outcome.  相似文献

Origins of language delay in abused infants   总被引：1，自引：0，他引：1  
This paper presents a reanalysis of data collected in a study of abusing mother-infant pairs, emphasizing the failure of infants with a history of physical abuse to develop appropriate language skills. Bayley Mental Development indices of abused infants decreased with age. This decrease was attributable largely to the failure of abused infants to pass verbal items. None of the abused children had any verbal communication skills. Results are discussed in relation to patterns of maternal ignoring and lack of verbal stimulation.  相似文献

Five hundred eighty-seven women in a combined Maternity-Infant, Children and Youth project were interviewed at between 3 and 6 months of gestation by a skilled masters degree social worker (M.S.W.) using a Family Stress Checklist developed at the University of Colorado Health Sciences Center. Only 7% of the women were scored as “high risk” for serious parenting problems. Neither single status nor teenage status increased the risk significantly. A review of charts of 100 of the children whose mothers had been considered “at risk” was conducted 2 to 2.5 years later, and compared with 100 charts on children whose mothers had been considered at “no risk,” giving the following results: Twenty-five children had experienced failure to thrive, neglect or abuse. Twenty of these were from the original high risk mothers, giving an incidence of neglect/abuse in that group of 52%. The no risk control group of 100 mothers showed a 2% incidence of abuse/neglect; a low risk group showed a 4% incidence of abuse/neglect; and a mid-score group had an abuse/neglect rate of 5%. The scale proved a remarkably accurate predictor, with a sensitivity (percent correct negatives) of 89%. The authors suggest use of such scales prenatally or even before conception as a step toward the development of true preventive measures.  相似文献

A theoretical model of early environment action was examined on a sample of 282 infants representing two racial groups (Caucasian, African-American). Children were obtained from three different sites in the United States. The model examined included the following variables: socioeconomic status (SES), early cognitive status (Bayley MDI at 12 months), stimulation within the home environment (subscales from the HOME Inventory at 12 and 24 months), parents use of negative control (subscales from the HOME Inventory at 12 and 24 months), and later cognitive status (36-month Stanford-Binet IQ). Structural Equation Modeling (SEM) with the LISREL software was used to confirm the fit of the model for African-Americans and Caucasians and for males and females separately. The models for males and females had similar structures, but not equal coefficients for all paths in the model. The models showed significant paths from socioeconomic status and early cognitive status to stimulation with the home environment, a significant path from SES to negative parental control, and a significant path from stimulation within the home environment to later cognitive status. The models for African-Americans and Caucasians differed in structure. For African-Americans, there was no evidence that the link between SES and 36-month IQ was mediated through negative control but SES and early cognitive status were linked to later IQ via the amount of stimulation provided in the home. For Caucasians, early cognitive status did not appear related to 36- month IQ but negative control did appear to mediate the relation between SES and IQ.  相似文献

Picturebook reading is a common form of interaction between parents and young children. This study examined developmental changes and socioeconomic differences in picturebook interactions of motherinfant Argentine dyads. 21 middle and 18 low SES mothers with their 12 to 24 months-old infants interacting with two different books, were observed. It was found that mothers of both SES groups adjusted the level of their demands not only to the task requirements (books) but also to the age of the infant. However, it was also found that the style of the interaction was different depending on the SES of the mother-infant pair. A more demanding and elaborated maternal language along with a linguistically more competent child were found in the middle SES group.  相似文献

40 middle-class mothers and their 12-month-old infants participated in an examination of the extent to which infant sociability and infant home experiences were correlated with cognitive capacity. Results indicated that the measures of the home environment (including Caldwell's Home Observation for Measurement of the Environment [HOME] inventory) were not correlated with the measures of cognitive competence (Bayley Mental Development Index [MDI], Ordinal Scales of Psychological Development) except among firstborns. Measures of the home environment were, however, correlated with measures of infant sociability (assessed inside and outside the test situation): sociable infants had sociable mothers. The infants' reactions to strange adults clearly influenced their performance in testing situations. Strong relationships were found between both measures of sociability and both measures of cognitive competence. The sociable friendly infants received higher scores on both cognitive tests than the less sociable babies did.  相似文献

This seven-week study examined the effects of the Neurological Impress Method and Read Two Impress on reading comprehension, fluency, and students’ attitude toward reading. The 57 first-, second-, and third-grade students were randomly assigned to three conditions and were pre- and posttested on eight reading measures. Several 3 × 2 factorial analyses of variance revealed significant interaction effects on retell, comprehension questions, and the multidimensional fluency scale as well as time effects on words read correctly per minute and word recognition accuracy. Moreover, a comparison of mean difference effect sizes favored the treatment groups on all reading fluency and comprehension measures. The interventions, however, had little effect on students’ attitude toward reading. Practical implications and future research directions are also discussed.  相似文献

Despite dramatic increases in recent decades in the number of employed mothers with children under 3 years of age and the greater utilization of nonmaternal child-care services (particularly unregulated family day care), little is known about the nature and quality of care provided to these infants by their employed mothers and substitute caregivers. This study was conducted to provide a comparative assessment of maternal and nonmaternal infant caregiving practices in own-home and unregulated family day-care homes, respectively. 30 caregivers (10 employed mothers, 10 substitute caregivers, and 10 nonemployed mothers) were observed in interaction with 5-6-month-old infants using Yarrow, Rubenstein, and Pedersen's Home Environment and Mother-Infant Interaction scales. While no differences were observed in the caregiving of employed and nonemployed mothers, both of these groups exceeded the sitters in socially mediated stimulation, contingent responsiveness, positive affect, and overall level and variety of social stimulation. In addition, employed mothers provided more tactile-kinesthetic, visual, and auditory stimulation to their infants than did the substitute caregivers. However, no differences were found between the infants reared in the home and day-care settings in Bayley Mental and Psychomotor developmental abilities. Evidence implicated group size (total number of children) in the quality of caregiving in family day-care homes. The impact of daily separations and qualitatively different caregiving experiences on infants is discussed.  相似文献

Inconsistent response patterns have been used with other measures to screen for child maltreatment. To date the inconsistency (IC) scale, a validity scale on the Child Abuse Potential (CAP) Inventory, has not been used as a screening criterion for physical child abuse. The present study examined the responses of 89 physical child abusers and 108 comparison subjects to determine if the CAP Inventory IC scale has any utility in the screening for physical child abuse. While results indicated the CAP Inventory IC scale scores were significantly higher for the physical child abuse group, a series of discriminant analyses indicated that the IC scale did not account for any meaningful variance after variance related to child abuse factors was removed. Further, the results indicated that dependence on the IC scale alone for physical child abuse screening purposes could be expected to produce excessive false positive and false negative classifications.  相似文献

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.  相似文献

Although a childhood history of abuse is related to parental child abuse, many parents with a history of abuse are not abusive. To determine the effects of a childhood history of abuse on adult child abuse potential, a modified Conflict Tactics Scale (CTS) and the Child Abuse Potential (CAP) Inventory were administered to matched groups of physically abusive mothers with a childhood history of abuse, nonabusive comparison mothers with a childhood history of abuse, and nonabusive comparison mothers without a childhood history of abuse. The modified CTS asked about childhood events and was used to confirm a childhood history of abuse. As expected, the CTS verbal and violence scales were higher for the abusive and nonabusive mothers with a childhood history of abuse. None of the CTS scores were different for the abusive and nonabusive mothers with a childhood history of abuse. In contrast, the CAP abuse scores distinguished between all three study groups. However, on the CAP factor scales, only the rigidity and unhappiness factors discriminated between abusive and nonabusive mothers with a childhood history of abuse. Nonabusive mothers with a childhood history of abuse were less rigid in their child expectations and were happier in their interpersonal relationships than abusive mothers with a childhood history of abuse.  相似文献

Two complementary studies focused on stability of infant temperament across the 1st year and considered infant age, gender, birth order, term status, and socioeconomic status (SES) as moderators. Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (< 9 months) interassessment intervals and small to medium for longer (> 10 months) intervals.  相似文献
