Anxiety of childhood is a common and serious condition. The past decade has seen an increase in treatment-focussed research, with recent trials tending to give greater attention to parents in the treatment process. This review examines the efficacy of family-based cognitive behaviour therapy and attempts to delineate some of the factors that might have an impact on its efficacy. The choice and timing of outcome measure, age and gender of the child, level of parental anxiety, severity and type of child anxiety and treatment format and content are scrutinised. The main conclusions are necessarily tentative, but it seems likely that Family Cognitive Behaviour Therapy (FCBT) is superior to no treatment, and, for some outcome measures, also superior to Child Cognitive Behaviour Therapy (CCBT). Where FCBT is successful, the results are consistently maintained at follow-up. It appears that where a parent is anxious, and this is not addressed, outcomes are less good. However, for children of anxious parents, FCBT is probably more effective than CCBT. What is most clear is that large, well-designed studies, examining these factors alone and in combination, are now needed.  相似文献

Throughout the early 1940s, a host of rumors relating to the Second World War began to circulate, leading the government to establish various committees and undertake multiple projects intended to counteract rumors that were believed to threaten civilian morale and compromise national security. Simultaneously, social scientists also began taking measures to study and combat rumor. Such efforts included the institution of several community groups, deemed "rumor clinics," that aimed to decrease the prevalence of wartime rumor by educating the general public. This article outlines the rise and fall of rumor clinics, focusing specifically on the shifting boundaries and the mounting tensions between the United States government and social scientists in the study of rumor during World War II.  相似文献

This article examines the role of motivational factors in affective forecasting. The primary hypothesis was that people predict positive emotional reactions to future events when they are motivated to enhance their current feelings. Three experiments manipulated participants' moods (negative vs. neutral) and orientation toward their moods (reflective vs. ruminative) and then assessed the positivity of their affective predictions for future events. As hypothesized, when participants adopted a reflective orientation, and thus should have been motivated to engage in mood-regulation processes, they predicted more positive feelings in the negative than in the neutral mood condition. This pattern of mood-incongruent affective prediction was not exhibited when participants adopted a ruminative orientation. Additionally, within the negative mood condition, generating affective forecasts had a more positive emotional impact on reflectors than on ruminators. The findings suggest that affective predictions are sometimes driven by mood-regulatory motives.  相似文献

The authors tested the hypothesis that children who are maltreated earlier in life are at greater risk for poor psychological functioning in adulthood than those maltreated later in life. Age of onset of maltreatment was assessed with 3 classifications: (a) continuous (ages 0-11 years); (b) dichotomous (early [ages 0-5 years] vs. later [ages 6-11 years]); and (c) developmental (infancy [ages 0-2 years], preschool [ages 3-5 years], early school age [ages 6-8 years], and school age [ages 9-11 years]). Individuals with documented cases of physical and sexual abuse and neglect prior to age 12 (N=496) were followed up and assessed in adulthood. Results indicated that an earlier onset of maltreatment, measured dichotomously and developmentally, predicted more symptoms of anxiety and depression in adulthood, while controlling for gender, race, current age, and other abuse reports. Later onset of maltreatment, measured continuously or developmentally, was predictive of more behavioral problems in adulthood. Implications for the assessment of maltreated children, the prevention of adult psychopathology, and the classification of age of maltreatment onset are discussed.  相似文献

Expanded newborn screening programs and subsequent detection of rare genetic disorders challenge parents and their medical providers to learn about the treatment and management of these disorders. Many people seek medical information on the Internet but may encounter requests for registration or fees, or find that resources are out of date, difficult to understand, or buried in advertisements. The U.S. National Library of Medicine (NLM), a component of the National Institutes of Health, provides web-based resources that address the challenges of newborn screening education. These resources include MedlinePlus, Genetics Home Reference, ClinicalTrials.gov, and PubMed. NLM websites are not commercial, do not require registration or fees, and provide varied levels of information for a continuum of audiences from low-literacy consumers to health professionals. Using phenylketonuria as an example, this study describes the information that parents and their medical providers can find through NLM resources. NLM has embraced the digital age and provides the public with reliable, accurate, and up-to-date educational materials.  相似文献

The authors argue that a high-organizational error management culture, conceptualized to include norms and common practices in organizations (e.g., communicating about errors, detecting, analyzing, and correcting errors quickly), is pivotal to the reduction of negative and the promotion of positive error consequences. Organizational error management culture was positively related to firm performance across 2 studies conducted in 2 different European countries. On the basis of quantitative and qualitative cross-sectional data from 65 Dutch organizations, Study 1 revealed that organizational error management culture was significantly correlated with both organizational goal achievement and an objective indicator of economic performance. This finding was confirmed in Study 2, using change-of-profitability data from 47 German organizations. The results suggest that organizations may want to introduce organizational error management as a way to boost firm performance.  相似文献

Both the distinctiveness heuristic and discrepancy detection hypotheses were investigated by independently manipulating both schema consistency and incidental suggestion in an eyewitness memory paradigm. A sequence of slides was shown, followed by a postevent questionnaire that contained both schema-typical and schema-atypical information. Fifteen minutes later, a source-monitoring task was administered. In Experiment 1, the proportion of source misattribution errors was greater for schema-typical items than for schema-atypical items, and the proportion of errors on suggested items was greater than that on control items. Suggestion affected schema-typical and schema-atypical items equally, providing no support for the predictions of either hypothesis. In Experiment 2, the interval between the questionnaire and the source test was manipulated. The results of Experiment 1 were replicated under the short delay, whereas the proportion of errors increased under the long delay. An associative network model involving two types of episodic traces was used to account for the results.  相似文献

First-order time remaining until a moving observer will pass an environmental element is optically specified in two different ways. The specification provided by global tau (based on the pattern of change of angular bearing) requires that the element is stationary and that the direction of motion is accurately detected, whereas the specification provided by composite tau (based on the patterns of change of optical size and optical distance) does not require either of these. We obtained converging evidence for our hypothesis that observers are sensitive to composite tau in four experiments involving relative judgments of time to passage with forced-choice methodology. Discrimination performance was enhanced in the presence of a local expansion component, while being unaffected when the detection of the direction of heading was impaired. Observers relied on the information carried in composite tau rather than on the information carried in its constituent components. Finally, performance was similar under conditions of observer motion and conditions of object motion. Because composite tau specifies first-order time remaining for a large number of situations, the different ways in which it may be detected are discussed.  相似文献

Behcet's disease is a chronic relapsing-remitting, multi-system inflammatory disorder of unknown etiology, characterized by recurrent oral and genital ulcers, uveitis, and skin lesions. The most common central nervous system findings are demyelization and perivascular cell infiltration; meningoencephalitis, cerebral atrophy, and vascular thrombosis may also occur. Neuropsychiatric symptoms may include: paroxysmal dystonia, parkinsonism, delirium, hallucinations, and behavioral disturbances. We report an unusual case of explosive onset of motor and vocal tics with obsessive-compulsive symptoms in a 22-year-old male with Behcet's disease. The putative roles of infection and autoimmune mechanisms in the pathogenesis of tics and obsessive-compulsive symptoms are explored.  相似文献

Cognitive models indicate that there are multiple ways of completing the same task. This implicit degeneracy cannot be revealed by functional imaging studies of normal subjects if more than one of the sufficient neural systems is activated. Nor can it be detected by neuropsychological studies of patients because their performance might not be impaired when only one degenerate system is damaged. We propose that degenerate sets of sufficient neural systems can only be identified by an iterative approach that integrates the lesion-deficit model and functional imaging studies of normal and neurologically damaged subjects.  相似文献
