Examined the performance of 42 middle- and 42 low-income kindergarten children on arithmetic calculations presented in a nonverbal format as well as in 3 different verbal formats. On the nonverbal task, the child was shown an initial set of disks, which was then hidden with a cover. The set was transformed by adding or removing disks. After the transformation, the child's task was to construct an array of disks that contained the same number of disks as in the final hidden set. A significant interaction between income level and task format was obtained. Although middle-income children performed better than low-income children on each of the verbal calculation tasks, the 2 income groups did not differ in performance on the nonverbal calculation task. The findings suggest that the nonverbal task format is less sensitive to socioeconomic variation than are the verbal task formats. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

During the period 1988-1992, a total of 4,030 malignant neoplasms were recorded in Kingston and St. Andrew, Jamaica. These comprised 1,829 in males and 2,201 in females. Histological confirmation was obtained in 83.4%. The crude incidence rate for males was 128.5, and 136.2 for females. The age-standardized rates (ASR) were 179.9 for males and 166.1 for females. Age-specific rates by site, sex and age are tabulated. Attention is drawn to increased incidence for cancers of prostate, larynx, bronchus and non-Hodgkin's lymphoma in males. There was also an increase in female breast cancer (crude rate 36.0; ASR 47.1). Invasive cervix cancer has shown no significant change in incidence. Neoplasms of the body of the uterus have increased (crude rate 7.6; ASR 9.5). The rise in cancer of breast and body of uterus suggests that the influence of exogenous oestrogens should be considered. 相似文献

Studied the effect on medical utilization when psychological care was provided to 63 children and adolescents whose low-income families were members of a completely subsidized health program. Comparisons of medical visits were made over a 2-yr period for 3 groups: a treatment group of registrants receiving psychological services; a control group matched with the treatment group according to age, sex, ethnicity, medical utilization, and psychological distress; and a group matched only by age, sex, and ethnicity. Results indicate that registrants who received psychological treatment had significant decreases in overall medical utilization, whereas there were no decreases in the other 2 groups. Findings are consistent with earlier research but extend the pattern of results into younger populations as well as low-income families.

The effects of an interactive book reading program were assessed with children from low-income families who attended subsidized day-care centers in New York. The children entered the program with language development in standard English vocabulary and expression that was about 10 mo behind chronological age on standardized tests. Children were pretested and assigned randomly within classrooms to 1 of 3 conditions: (1) a school plus home condition in which the children were read to by their teachers and their parents, (2) a school condition in which children were read to only by teachers, and (3) a control condition in which children engaged in play activities under the supervision of their teachers. Training of adult readers was based on a self-instructional video. The intervention lasted for 6 wks, at which point children were posttested on several standardized measures of language ability that had been used as pretests. These assessments were repeated at a 6 mo follow-up. Educationally and statistically significant effects of the reading intervention were obtained at posttest and follow-up on measures of expressive vocabulary.

This study examined developmental associations between growth in domain-general cognitive processes (working memory and attention control) and growth in domain-specific skills (emergent literacy and numeracy) across the prekindergarten year and their relative contributions to kindergarten reading and math achievement. One hundred sixty-four Head Start children (44% African American or Latino; 57% female) were followed longitudinally. Path analyses revealed that working memory and attention control predicted growth in emergent literacy and numeracy skills during the prekindergarten year and that growth in these domain-general cognitive skills made unique contributions to the prediction of kindergarten math and reading achievement, controlling for growth in domain-specific skills. These findings extend research highlighting the importance of working memory and attention control for academic learning, demonstrating the effects in early childhood, prior to school entry. Implications of these findings for prekindergarten programs are discussed, particularly those designed to reduce the school readiness gaps associated with socioeconomic disadvantage.

The effects of a voluntary summer reading intervention with and without a parent training component were evaluated with a sample of low-income Latino children from language minority families. During the last month of 4th grade, 370 children were pretested on a measure of reading comprehension and vocabulary and were randomly assigned to (a) a treatment group in which children received 10 self-selected books during summer vacation, (b) a family literacy group in which children received 10 self-selected books and were invited with their parents to attend 3 summer literacy events (2 hr in length), and (c) a control group. Although children in the treatment group and the family literacy group reported reading more books than the control group, there was no significant effect on reading comprehension and vocabulary. Recommendations for improving the efficacy of the intervention are discussed, including efforts to improve the match between reader ability and the readability of texts and the instructional goals of the family literacy events.

To determine the impact of an experimental approach to case management on use of child health clinic and immunization services, a nonequivalent control group with covariate measures design was employed in a sample of 98 infants from low-income families. The innovative pattern of care featured continuity of care; a single public health nurse (PHN) provided child health care to an infant by integrating case management and preventive services. In contrast, the customary pattern of child health care was characterized by fragmentation of services. Case management was segregated from preventive services, and multiple PHNs delivered care to an infant. As predicted, experimental-group infants (44%) were more likely to achieve adequate child health clinic services than control-group infants (8%) (p < 0.001). Moreover, the cost-effectiveness (C/E) ratio (dollar cost per effective intervention) for adequate child health clinic visits in continuous care ($523) was one-fifth of that in fragmented care ($2,900). The C/E ratio related to adequate immunization was 8% less in continuous care ($359) than in the fragmented approach ($386), although the difference in rates of adequate immunization was nonsignificant (experimental group, 64%; control group, 60%). These findings suggest that continuous PHN care with integrated case management is a more effective, cost-efficient approach to critical child preventive services than the customary, segregated case-management approach. 相似文献

The authors examined the achievement-related beliefs and behaviors of parents of economically disadvantaged African American youth, and the relations among parental factors and children's academic self-concept and achievement. Forty-one children and their primary caregivers were interviewed. Parents reported on their academic-related beliefs and behaviors. Children completed measures of academic self-concept and 2 standardized achievement tests: 1 during the summer and 1 at the end of the following school year. Significant and positive relations were found between parental belief and behavior measures within the domains of reading and math; however, parental beliefs were more strongly linked with child outcomes than were parents' achievement-oriented behaviors. The relation between parental beliefs and child outcomes was not mediated by children's academic self-concept. Results are discussed in light of models of family influences on achievement.

This study assessed psychological distress and psychiatric disorder in high-risk women enrolled in a hereditary breast and ovarian cancer registry, and it evaluated the concordance between self-report data and interview-based psychiatric diagnosis. A sample of 464 women completed the Hopkins Symptom Checklist-25 and were interviewed using modules of the Structured Clinical Interview for DSM-IV. Level of psychological distress and the prevalence of psychiatric disorder were low and in the range that would be expected for a sample of community-residing women. Screening proved inefficient: Less than 10% of distressed women met criteria for a clinical disorder. High-risk women seeking genetic testing in research settings may not require extensive psychological screening and diagnostic assessment. Caution is expressed about possible self-selection biases in women enrolled in hereditary cancer registries. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Investigated the problem behaviors of 35 physically abused 6–16 yr olds in comparison with 36 nonabused children from a child welfare agency and 35 nonabused children in the community. Parental report of behavioral strengths and weaknesses was examined by administering the Child Behavior Profile. Results concur with those of previous reports that abused children display a significantly greater number of behavior problems and fewer social competencies than normals. The behavior patterns of abused Ss closely resembled the range of behavior problems shown by Ss from distressed families in which abuse was not present.

Briefly discusses the role of the mother in providing noncontingent love and that of the father in providing performance-contingent love. 19 black 8-12 yr. olds from father-present and 19 from father-absent families who had been referred to a guidance clinic for aggressive behavior were tested on the Wiltwyck Family Interaction Apperception Test (S. Minuchin, et al.). While Ss from father-present families did not give more frequent consequences for aggression, there were significant differences between the 2 groups in perceptions of the administrator of punishment. Despite the fact that the stories routinely involved mother rather than father as punisher, Ss from father-present families related stories in which punishment came from the family more frequently (p 相似文献

Effects of student control and choice on engagement in a CAI arithmetic task in a low-income school.
Fisher Maurice D.; Blackwell Laird R.; Garcia Angela B.; Greene Jennifer C. 《Canadian Metallurgical Quarterly》1975,67(6):776
To investigate choice in a computer-assisted instruction (CAI) arithmetic task, 38 4th and 5th graders from a low-income school were assigned to either a choice or a yoked control condition. The choice condition allowed selection of arithmetic problems, while the yoked condition allowed no choices. Choice Ss showed significantly more task engagement. There were 2 distinctive choice patterns, with some Ss consistently choosing the easiest problems and others the most difficult ones. Problem difficulty and engagement were linearly related for all choice subgroups, with engagement highest for the easiest problems and lowest for the most difficult. Choice and yoked Ss differed significantly on 3 behavioral locus of control dimensions (stable-unstable, internal-external, and self-other attributions). While choice may be motivating, for some children it can result in poor academic performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families from predominantly low-income, rural communities. Maternal behavior, family income-to-need ratio and social advantage, and child temperament, attention, and mental development were assessed, and children's saliva was sampled before and after standardized procedures designed to elicit emotional arousal. Maternal engagement in infancy was associated with greater cortisol reactivity at the infancy assessment and with reduced overall cortisol level at the toddler assessment. Also at the toddler assessment, child attention, mental development, and temperamental distress to novelty were associated with increased cortisol reactivity and regulation, whereas temperamental distress to limitations and African American ethnicity were associated with reduced cortisol reactivity. Findings are consistent with prior work linking early caregiving to the development of the hypothalamic-pituitary-adrenal axis stress response system and with a conceptual model in which developing temperament is characterized by the interplay of emotional reactivity and the emergence of the ability to effortfully regulate this reactivity using attention.

The United States end-stage renal disease (ESRD) population is growing progressively older. As a percentage of the overall ESRD population, the number of patients 65 years of age and older approached 40% by 1989. However, the percentage of ESRD patients with a functioning transplant was only 2.7% in this age group. Success of transplantation in geriatric ESRD patients over the last decade is due to improved patient selection as well as the use of cyclosporine A and lower doses of corticosteroids, with the achievement of 1-year patient and graft survival rates of 85% and 75%, respectively. For patients older than 60 or 65 years, the 5-year "functional" graft survival is 55% to 60%. Although overall results are excellent, the management of transplantation in the elderly requires an understanding of pharmacology, immunology, and physiology peculiar to this age group. Since the elderly have a degree of immune incompetence, they require less aggressive immunotherapy. Elderly patients have decreased hepatic enzyme activity, especially the P450 system, and therefore require a lower cyclosporine dose. Although elderly patients experience less rejection episodes than younger patients, graft loss in the elderly transplant recipient is due mainly to patient death. Most common causes of death in the elderly transplant recipient are cardiovascular disease and infection related to peaks of immunosuppression. Shortage of cadaver kidneys and limited life expectancy of the geriatric ESRD patient make allocation of cadaver kidneys to patients over 70 years (and even 65 years) a controversial issue and an ethical dilemma. Use of elderly cadaver donors (over 55 to 60 years) is associated with inferior success rates and is not an optimal solution to shortage of cadaver kidneys. 相似文献

Over 1300 severely malnourished children (< 60% of US National Center for Health Statistics weight-for-height, with edema, or both) are admitted each year to the Children's Nutrition Unit in Dhaka. Fatality during treatment is low and recovery is rapid. Our aim was to determine whether this initial success is sustained when children return home. A previous attempt to address this question was frustrated by the difficulty in tracing children after discharge because most are from slum settlements and families move frequently. This prospective study with fortnightly monitoring was therefore undertaken. The main outcomes of interest were anthropometric status, relapse, morbidity, and mortality. Children (n = 437) who had been treated for severe malnutrition when aged 12-59 mo and had reached the discharge criterion of 80% of weight-for-height, were followed for the next 12 mo. During follow-up, 7.5% were lost without trace, 0.6% relapsed, and 2.3% died. Morbidity was high, with a mean of seven episodes of diarrhea during the year. Outpatient visits for diarrhea occurred for 67% of children, and 58% had pneumonia (10% had pneumonia three times). After 12 mo, mean weight-for-height was 91% (-0.92 z score) but mean height-for-age remained at 84% (-4.14 z score). Weight gain, but not height gain, tended to be lower in children who experienced more diarrhea. Fever and cough were not associated with either weight or height gain. The high prevalence of illness highlights the need for continued accessible health care and for interventions to reduce disease acquisition. 相似文献

The epidemic of drug abuse has overwhelmed men, women and children and caused incalculable damage to an honoured structure in human civilization--the family. Moreover, during the past decade, increasing numbers of pregnant drug-dependent women have been presenting themselves to medical facilities, some to receive ongoing prenatal care, but others only to deliver their babies without the benefit of any medical services. The present chapter reviews the current literature, as well as the experiences of the author, with regard to the sociomedical characteristics of pregnant, drug-dependent women. The effects of substances of abuse on pregnancy, the foetus and the newborn with respect to morbidity and mortality are presented. Recommendations for management of both the pregnant drug-dependent women and her child, on the basis of clinical research, are also outlined. Although overall medical advances have escalated during the past three decades, there is still much to learn with regard to the effects of drugs of abuse upon families. Moreover, methods of prevention and treatment still need considerable study. By re-evaluating the areas of strength and weakness in the body of available knowledge, future research will be able to enhance the ability to help those unfortunate families that are effected by substance abuse. 相似文献

The reliability and validity of mother's reports of their infants' exposure to secondhand smoke (SHS) were examined in an ethnically diverse sample of low-income, low-education families (N?=?141 mothers). At baseline and posttest, smoking mothers reported about their infants' SHS exposure at different locations and by different sources during the previous week. Findings show that mothers can give reliable accounts of the degree to which they contribute to their babies' SHS exposure. Mothers are able to differentiate between their own smoking behavior and the extent to which they expose their infants. Consistent with the overall exposure pattern, exposure caused by the mother and exposure occurring at home showed the strongest associations with biological and environmental measures. These findings suggest that smoking mothers can provide reliable and valid reports of the degree to which their infants are exposed to SHS.
