Prenatal smoke exposure (PSE) is a risk factor for adverse outcomes in the offspring, including those affecting psychological development. However, it is uncertain whether these associations are the direct result of PSE or other confounding factors. The aim of this study was to examine the possible relationship between PSE and behavioral development in children at 7.5 years of age, considering several prenatal, neonatal and postnatal covariates. A cohort of 266 mother-child pairs was followed from the first trimester of pregnancy until the children reached 7.5 years of age. PSE was assessed using a questionnaire from prenatal clinical records and corroborated by plasma cotinine determinations in the first and second trimesters and in the cord. Mother-child pairs were classified into one of four groups: unexposed, exposed to passive smoking, first trimester active smoking only and active smoking throughout pregnancy. Child behavior was assessed using the Child Behavior Checklist for ages 6–18 and the Childhood Autism Spectrum Test. In multiple linear regression models, smoking during pregnancy was associated with higher scores in affective problems (β?=?0.298; p?=?0.004). No significant associations were found between smoking during pregnancy and externalizing problems. Findings indicate that PSE is negatively associated with behavioral development in childhood.

Thirty-three twelve-month-old infants were divided into three groups based on the frequency and length of naturally-occurring nontraumatic separations from mother during the first year. One group had experienced only brief separations when left with a babysitter for an evening. A second group had been left once or twice for an average of five days while parents vacationed. A third group had been left regularly and frequently during the daytime, usually because mother was working. These groups were compared on measures of reaction to separation and reunion, in the home and in the laboratory, at one year of age. No group differences were found on any of the dependent variables. It is suggested that the quality of substitute care is probably more important than separation per se in mediating the impact of employment or daycare on infant development.  相似文献

The Parent/Toddler Education and Guidance Group is designed for parents and their 18–36 month old children who are experiencing mild to moderate difficulties with the developmental issues of toddlerhood. The goal of the group is to help parents support their child's growing autonomy, and create a new level of communication between parent and child. The program is described in a general way and is then illustrated in examples of two cases.  相似文献

A family systems approach provides a context for the development and maintenance of dyadic attachment relationships. An attachment approach provides a focus on the expression of and response to attachment behavior within a family. Uniting the two approaches has implications for both research and intervention. Characteristics of attachment theory and family systems theory are briefly outlined: Both involve systemic thinking. Different styles of interacting at the level of the family as a whole, working models of relationships, and dyadic interactions appear to correspond in a coherent way. Further research is needed in order to identify which dimensions of family functioning are relevant to the development of secure attachments, and how the relevant dimensions may change with age and stage in the family life cycle. This will provide targets for preventive interventions, with the development of secure relationships as a primary goal.  相似文献

This article examines the usefulness of the Family Assessment Device(FAD) in assessing family functioning with school-aged children (under 12 years of age) compared to children 12 and older and mothers. FAD reports from 194 children with asthma (132 under 12 years; 62 12 years and older) were evaluated in comparison to mothers' FAD reports as well as mothers' reports on two other family functioning measures: the Family Inventory of Life Events (FILE) and the Impact on Family (IOF) scale, both relevant to functioning in families with children with asthma. Although FAD scale reliabilities were lowest in younger children (alpha = 48-.79), good concurrent validity was found with mothers' reports on the three different measures of family functioning. Older childrens' FAD scales showed good reliability (> .70) but poorer agreement with the various maternal measures. With modifications to make items more structured and simplified, the FAD could be tried with younger children, although documentation of improved reliability is needed before more widespread use with school-aged children is advocated. The measure already shows good agreement with maternal report in this younger age group, which likely would be strengthened with improved reliability. FAD reports in older children correlated less well with maternal measures, but may represent nonredundant information on family health from an independent perspective and are worth considering in addition to mothers' perspectives.  相似文献

Adulthood encompasses a large time span and includes a series of psychosocial challenges (E. H. Erikson, 1950). Five aspects of personality (identity certainty, confident power, concern with aging, generativity, and personal distress) were assessed in a cross-sectional study of college-educated women who at the time of data collection were young adults (age: M = 26 years), middle-aged adults (age: M = 46 years), or older adults (age: M = 66 years). Respondents rated each personality domain for how true it was of them at the time, and they then rated the other 2 ages either retrospectively or prospectively. Results are discussed with attention to the ways in which women's adult development may have been shaped by experiences particular to both gender and birth cohort, and to how these women fit with E. H. Erikson's theory of adult development.  相似文献

Using 4 experiments, the authors examined how stereotypic information about teammates influences social loafing and compensation during collective tasks. In each experiment, participants performed better on cognitive tasks when there was a poor (vs. good) fit between the stereotypic strengths of their partner and the requirements of the task. This pattern occurred whether participants used gender stereotypes (Experiment 1) or occupational stereotypes (Experiments 2 to 4) and occurred even when participants only anticipated working on a collective task (Experiment 4). In Experiment 3, the pattern occurred only in the collective (not in the coactive) condition, providing direct evidence for social loafing. Together, these results suggest that people use stereotypes to tune their motivation to optimize the ratio of their own individual effort to the team's expected output.  相似文献
