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.

Two studies were conducted to determine the impact of infants' attachment classifications and behaviors on naive adults' impressions of their behavior and mental health. In Study 1, three groups of 44 adults viewed a videotape of episode 8 of the Strange Situation for either an avoidant, a resistant, or a secure male infant. After viewing the videotape, they made judgments about aspects of the infant's mental health. Adults viewed the resistant baby as less socially competent and more negative in affect than the other two babies and the secure baby as the least independent of the three babies. Parents rated babies as more intelligent than did nonparents. In Study 2, 15 parents were matched on race and gender with 15 nonparents. All adults viewed a videotape of the reunions of two secure, two avoidant, and two resistant male infants. Avoidant babies were viewed as more socially competent and independent than secure babies and the C2 baby was viewed as the least intelligent, least independent, least socially competent, and most affectively negative of the infants. Results are interpreted as underscoring the need to educate parents and paraprofessionals about the importance of infant distress and physical contact with parents.  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

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

MENSTRUAL JOY The Construct and Its Consequences   总被引:1,自引:0,他引:1  
Fifty female college students participated in a study of women's health. In a counterbalanced design, half of the participants completed the Menstrual Joy Questionnaire (MJQ) and the Menstrual Attitude Questionnaire (MAQ) in the first testing session. A week later they completed the Menstrual Distress Questionnaire (MDQ) and the Menstrual Attitude Questionnaire. The other participants completed the MDQ and MAQ in the first session and the MJQ and MAQ in the second. A multivariate analysis of variance revealed that those who received the MJQ first reported more positive cyclic changes on the MDQ and more positive attitudes on the MAQ. A follow-up study of 40 college students examined their responses to the MJQ. Participants reported that they were surprised or incredulous; most had not previously considered positive aspects of the menstrual cycle. Thirty percent reported that the MJQ had caused them to look at menstruation in a different way.  相似文献

Mandatory reporting laws, which vary slightly from state to state, require reporting by helping professionals when there is reasonable cause to suspect child abuse. Institutional Review Boards (IRBs) require researchers to warn subjects of this duty to report, which may have a chilling effect on subject rapport and candor. Certificates of confidentiality, in conjunction with other precautions, may reduce some barriers to valid research. Attempts to resolve problems created by reporting laws must produce the most valid research, while minimizing harm and distress to research participants, their families, and the researcher and meeting local and federal legal requirements.  相似文献

This study examined relations among spelling performance and students' beliefs about spelling, including self-efficacy for spelling ability, outcome expectancy for spelling, and attributions for good spelling across grades 4, 7, and 10. Spelling self-efficacy remained relatively constant across grades. Spelling outcome expectancies for adult life and school declined across grades, as did effort and ability attributions for spelling success, with a disproportional decrease in ability attributions between grades 4 and 7. Self-efficacy was the strongest predictor of spelling performance at all grade levels; attribution for ability entered into the regression for grade 4 students, while outcome expectancies for school and writing were more important in grades 7 and 10. Cluster analyses on the grade 10 sample showed that students with high efficacy as spellers and high outcome expectancy of spelling for writing were the best spellers, with the highest performance reserved for those who attributed good spelling more to effort than ability. The impact of spelling instruction on developing beliefs is discussed.  相似文献
