OBJECTIVE: The current study examines multiple empirically based perspectives (i.e., child, caregiver, and clinician) of behavior and functioning as they contribute to the clinical and psychosocial profile of children (aged 5 to 17.5 years) with reported histories of sexual abuse.METHOD: A large, multi-site data set of children referred into Comprehensive Community Mental Health Services both with and without reported histories of sexual abuse, was examined. Seven hundred and fifty-nine children with a reported history of sexual abuse were compared to 2722 without such a history on caregiver and child reported behavior, clinician rated functioning, diagnosis, demographic variables, and life challenges.RESULTS: The multiple perspectives contributed unique and specific information to regression models: caregiver-reported behavior contributed information about externalizing behavior while child-reported behavior added information about internalizing behavior and clinician ratings about self-harmful behavior. Children with reported histories of sexual abuse were also more likely to be female, Caucasian, and have reported histories of life challenges (e.g., physical abuse, substance use, running away). Child sexual abuse was associated with higher rates of depression and anxiety diagnoses, and lower rates of substance abuse, conduct, and attention deficit disorder diagnoses.CONCLUSIONS: The findings indicate that the profile of children entering into Comprehensive Community Mental Health Services with reported histories of sexual abuse, as compared to those without such histories, is complex and best understood via multiple perspectives. Caregiver, child and clinician rated information, when taken together, provide a comprehensive clinical and psychosocial profile around which to plan and implement individualized service plans.  相似文献

Children''s Use of Anatomically Detailed Dolls to Recount an Event   总被引:2,自引:0,他引:2  
The use of anatomically detailed dolls in child sexual abuse investigations has raised several controversial issues related to important theoretical questions in developmental psychology. The present study was designed to examine some of these issues in a methodologically sound experiment. 80 3- and 5-year-old children experienced a social interaction with a male confederate and were later tested under 1 of 4 recall conditions: reenactment with anatomically detailed dolls, reenactment with regular dolls, free recall with visual cues, or free recall without visual cues. The children were also asked a variety of specific and misleading questions, some of them dealing with acts associated with abuse ("He took your clothes off, didn't he?"). Both anatomically detailed and regular dolls along with other props aided 5-year-olds more than 3-year-olds in recounting the event. To use increased rather than decreased age differences. Anatomically detailed dolls did not foster false reports of abuse. Overall, 3-year-olds were more suggestible than 5-year-olds. The findings have implications for children's testimony in child abuse cases and for psychological theories concerning the effects of stimulus support on children's memory.  相似文献

The purpose of this study was to demonstrate the respective effects of cognitive abilities and personality traits on academic achievement. The subjects were 141 sixth-grade French adolescents (mean age: 12) who took three cognitive tests (g factor, numerical ability, and spatial ability) and answered a personality questionnaire based on the Big Five Model. Path analyses indicated that Openness-intellect had an effect on junior high school achievement in all disciplines, with most effects being indirect ones mediated by verbal achievement (French). Neuroticism-anxiety also had an effect, although not as marked and mainly on mathematics. Personality is complementary to abilities in predicting academic achievement. Possible conceptual extensions and field applications are addressed in the conclusion.  相似文献

Elsewhere, the authors have unpacked instructional leadership and have documented that such leadership is associated with more effective schools. Indeed, there has been for a considerable time nearly universal acceptance that learning-centered leadership should provide the central platform on which leadership is enacted. In this paper, a less sanguine narrative is provided on instructional management. Specifically, it documents that for all the evidence and recognition of importance, learning-focused leadership remains a small domain of action for leaders at the school and district levels. It then focuses on both the culture of the profession of school administration and the nature of schooling to explain why in the face of considerable energy and effort only marginal improvements have been realized in deepening instructional leadership. It closes with an analysis of possible paths going forward.  相似文献

ABSTRACT

Educational researchers have invested much in isolating the specific ‘drivers’ that influence school change and teacher professional development. In this vein, this article draws attention to necessarily situated understandings of practice development through research into the nature of ‘middle leading’ for site based education development in one primary school district in regional Australia. Drawing on practice theory, the analysis reveals how developing and sustaining change in schools is contingent on middle leaders’ insider knowledge, shared responsibility and capacity to sustain and ‘drive’ teachers’ learning. The article argues more situated understandings of middle leading practices are essential for sustainable educational reform.  相似文献

Free play patterns of black South African children in 16 day care centres were observed before and after the introduction of an enrichment package. The package consisted of a range of educational toys and cost US$12 per child. Results indicated that the enrichment was associated with changes in social interaction and play patterns, though not all these may have been positive. Results are discussed in terms of often unexpected impacts that intervention schemes can have in the developing world, even those specifically designed for a particular population.  相似文献

In contrast to dyslexia, in hyperlexia, there is precocious development of reading in the absence of other precocious skills, thus reading is significantly above expectation on the basis of prediction from age and intelligence. A psycholinguistic investigation is reported, of a 10 year old, non-autistic hyperlexic, on tasks of both written and auditory presentation of single words, sentences and text. M.S. shows good development of both phonological and lexical reading mechanisms. He does not display a pattern of reading performance which resembles any selective reading disorder and there is no evidence that the nature of his reading development, in relation to accuracy, is abnormal in style. However, reading accuracy is significantly better than both reading comprehension and auditory comprehension. The comprehension deficit does not affect language in an undifferentiated way. Semantic comprehension is normal for age but syntactic comprehension is significantly impaired. Thus, although there are no unusual dissociations in relation to reading accuracy, there is a significant dissociation between reading accuracy and reading comprehension, and also between semantic and syntactic comprehension of both written and auditory material which argues for modularity in the development of these subsystems.  相似文献

To begin an investigation of the cellular processes that underlie long-term memory in the nematodeCaenorhabditis elegans, it is first necessary to determine thatC. elegans is capable of retention over 24 h, and to investigate the factors that may influence the expression of long-term memory. In the present study, the effects of stimuli number, interstimulus interval (ISI), and training procedure on long-term retention of habituation were tested inC. elegans. At a long (60-sec) ISI, distributed training sessions produced long-term habituation retained for 24 h, whereas massed training sessions or training with few stimuli did not. When training was performed at a short (10-sec) ISI, long-term habituation was not detectable with testing at either a 10- or a 60-sec ISI. The long-term habituation observed after distributed training sessions at a 60-sec ISI was consistently expressed when the training procedures were varied. Thus it is clear thatC. elegans can reliably express long-term retention for distributed training sessions at a 60-sec ISI, making the system a candidate for further investigations into the cellular processes supporting memory.  相似文献
