Caregiving and infant behavior in day care and in homes.

Social interaction and play behavior were compared in community-based day care and at home for 2 matched groups of 18-mo-olds (30 Ss). Adult–infant, infant–peer, and infant–toy interaction were time sampled. More adult–infant play, tactile contact, and reciprocal smiling were found in day care. More infant verbal responsiveness to maternal talking, more infant crying, and more maternal restrictiveness were found at home. Developmental level of play with toys was higher in day care, a difference associated with interaction with peers. The importance of the infant in shaping the environment emerged clearly from the data; day care/home differences in adult–infant interaction were often a function of differences in infant as well as adult behavior. No adverse effects of daily mother–infant separation were noted in the daily social and play behavior of the day-care group. The importance of peers as social objects for the toddler emerged from this study. Peers seemed to contribute to the high levels of play and to the positive affect noted in day care and also seemed to facilitate separation from adult caregivers.

Exploring Work and Family Distractions: Antecedents and Outcomes.

Drawing from expansionist theory and time-based role-conflict theory, this research investigated antecedents and outcomes of time spent in 1 role while distracted or preoccupied by another role. Survey data from a sample of 171 working mothers generally supported hypotheses linking work and family distractions to role quality. Work-role overload was positively related to work distractions experienced at home, and traditional gender-role expectations were positively related to family distractions experienced at work. In terms of outcomes, work distractions at home were negatively related to job satisfaction. Results illustrate the importance of role quality and the efficacy of alternate operationalizations of role time in the effort to better understand the interface between work and family.

Home grown for reading: Parental contributions to young children's emergent literacy and word recognition.

This article provides an integrative review of key aspects of emergent literacy and specific home activities that empirical research has shown to support their development. Given the importance of word recognition in reading development, home contributions to word recognition as well as to four areas of emergent literacy that contribute to word recognition are highlighted. These include phonological awareness, letter knowledge, print concepts, and vocabulary. Particular attention is devoted to the activity of shared book reading to outline its different facets, changing nature, and potential impact on emergent literacy and word recognition skill.

A model of home care for high-risk childbearing families. Women with diabetes in pregnancy

With a national trend toward decreased hospitalizations for high-risk childbearing women, home care and follow-up services have gained increased importance. The Quality-Cost Model of Nurse Specialist Transitional Follow Up Care is presented as a method to provide home care for high-risk pregnant women, specifically those whose pregnancies are complicated by diabetes mellitus. The model offers opportunities for intensive education, assessment, intervention, and support throughout the pregnancy and postpartum period. In addition, this model can potentially decrease the burden of care on the woman and her family by providing a comprehensive program of home care, follow up, support, and education.     

Prognostic indicators and early home rehabilitation in elderly patients with hip fractures

A program for early mobilization in the hospital and rehabilitation at home after hip fracture was developed in cooperation with local health and social authorities and applied to 103 consecutive patients having a mean age of 75 years. All were admitted to the hospital from their own homes. Three fourths of the patients returned home directly after postoperative mobilization periods of usually two to three weeks in hospital. Four months after the fracture 81 of 99 surviving patients were at home, most of them having regained their prefracture functional status. One year after the fracture 91 patients were alive, and 78 of these were at home with no functional loss, compared with their condition at four months. Some of the social and medical factors which may already be pertinent to the recovery outcome at the time of fracture are identified. Eight to nine of ten patients with two or three positive factors ("healthy," living with someone, and ability to walk two weeks postsurgery) returned directly home. This study suggests the importance of intensive support, in the form of information to patients and relatives, and close cooperation between hospital staff and community care authorities. By this means, a continuity of care and early permanent independence can be achieved for elderly hip fracture patients and institutionalized rehabilitation can be reduced with benefit for both the individual and society.     

Maternal IQ and home environment as determinants of early childhood intellectual competence: A developmental analysis.

Children at risk for sociocultural mental retardation were studied longitudinally from birth to 4 yrs of age. Maternal IQs were assessed before the children's births, and children's IQs and home environments were assessed at regular intervals during the 1st 4 yrs of life. Multiple regression analyses were conducted to separate the contributions of maternal IQ and home environment to child IQ at 24, 36, and 48 mo. When the effect of maternal IQ was controlled, home environment's association with child IQ was significant only at 48 mo. When the effect of home environment was controlled, maternal IQ's association with child IQ was significant only at 24 mo. Taken together, the 2 predictors explained 11, 17, and 29% of the variance in child IQ at the 3 respective times. The overall pattern suggested a monotonic increase in the predictability of child IQ within the context of a shift in the relative importance of maternal IQ and home environment as predictors. The integration of the study of behavioral genetics with the study of the process of intellectual development requires an ontogenetic perspective.

"Cleaning-up cognition" in triple-response fear assessment through individualized functional behavior analysis

Despite the wish of the Japanese people to spend their final moments at home, the percentage of deaths at home among elderly is decreasing. Moreover, large variations in this rate were observed over the country. The present ecological study analyzed the relationship between the percentage of deaths at home for decedents aged 70 and over, and demographic, medical and socioeconomic characteristics. The data published in 1990 by the Japanese National Government were analyzed by correlation, principal-component, and multiple linear regression analyses. The results showed that the percentage of deaths at home for decedents aged 70 and over was positively associated with the number of persons per household, and the area of floor space per house. The divorce rate, the national tax per capita, and the mean length of hospitalization for stroke showed a negative association with the percentage of deaths at home. In the prefectures where the crude death rates of stroke and senility were high, elderly were more likely to die at home. These results suggested the importance of the number of family caregivers, and the housing conditions for terminal care at home. This research may lead to improve home medical assistance which is still underdeveloped in Japan.     

Home literacy activities and their influence on early literacy skills.

The relationship between the home environments of 66 children (aged 5.4–6.7 yrs) and their language and literacy development was examined. Parents (aged 28–46 yrs) of the children were interviewed regarding demographic information and home visits were conducted in which parents were observed reading with their children and interviewed about specific literacy practices. Children were assessed at approximately 9 mo intervals. After accounting for child age, parent education, and child ability as indexed by scores on a rapid automatized naming task and Block Design of the Wechsler Preschool and Primary Scales of Intelligence—Revised, shared book reading at home made no contribution to the prediction of the literacy skills of letter name and letter sound knowledge in kindergarten. In contrast, home activities involving letters predicted modest and significant amounts of variance. For the areas of receptive vocabulary and phonological sensitivity, neither shared book reading nor letter activities were predictive. Follow-up to mid-Grade 2 underscored the importance of letter name/sound knowledge and phonological sensitivity in kindergarten in accounting for individual differences in later achievement in reading comprehension, phonological spelling and conventional spelling.

Normal puerperium and breast-feeding

Mothers who have just given birth need support from medical staff and also from their home surroundings. The type of support given to mothers and their new babies varies in different countries and cultures, but should be equally adequate and beneficial. Breast-feeding, as the very best method of early nutrition of the newborn, is the central event of puerperium. Its importance, and other practical approaches during this period are discussed and reviewed.

Joint picture-book reading correlates of early oral language skill

The purpose of this study was to explore the relation between joint picture-book-reading experiences provided in the home and children's early oral language skills. Subjects were 41 two-year-old children and their mothers. Measures included maternal report of the age at which she began to read to the child, the frequency of home reading sessions, the number of stories read per week, and the frequency of visits by the child to the local library. Measures of language skill used were the child's receptive and expressive scores on the revised Reynell Developmental Language Scales. Multiple regression analyses indicated that picture-book reading exposure was more strongly related to receptive than to expressive language. Age of onset of home reading routines was the most important predictor of oral language skills. Directions of effect, the importance of parental beliefs as determinants of home reading practices, and the possible existence of a threshold level for reading frequency are discussed.     

Home numeracy experiences and children’s math performance in the early school years.

Children’s numerical competence in kindergarten is highly predictive of their acquisition of mathematics in Grade 1 and Grade 2, suggesting that experiences at home before schooling are important in understanding how numeracy develops. In this study, the mathematical skills of 146 children in Kindergarten, Grade 1, and Grade 2 were correlated with the frequency with which parents reported informal activities that have quantitative components such as board and card games, shopping, or cooking. Effect sizes were consistent with research relating home literacy experiences to children’s vocabulary. The present research supports claims about the importance of home experiences in children’s acquisition of mathematics. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
