This study examined whether the link between risk factors for conduct problems and low rates of participation in mental health
treatment could be decoupled through the provision of integrated prevention services in multiple easily-accessible contexts.
It included 445 families of first-grade children (55% minority), living in four diverse communities, and selected for early
signs of conduct problems. Results indicated that, under the right circumstances, these children and families could be enticed
to participate at high rates in school-based services, therapeutic groups, and home visits. Because different sets of risk
factors were related to different profiles of participation across the components of the prevention program, findings highlight
the need to offer services in multiple contexts to reach all children and families who might benefit from them.

Research has shown that prevention programming can improve community health when implemented well. There are examples of successful prevention in local communities, however many continue to face significant challenges, demonstrating a gap between science and practice. Common strategies within the United States to address this gap are available (e.g., trainings), but lack outcomes. Building community capacity to implement high quality prevention can help communities achieve positive health outcomes, thereby narrowing the gap. While there is ample research on the efficacy of evidence-based programs, there is little on how to improve community capacity to improve prevention quality. In order to narrow the gap, a new model of research—one based in Community Science—is suggested that improves the latest theoretical understanding of community capacity and evaluates technologies designed to enhance it. In this article, we describe this model and suggest a research agenda that can lead to improved outcomes at the local level. 相似文献

Family processes of communication, mutual support, and sustenance of cultural values can play vital roles in recovery from psychological and material damage in societies afflicted by terror. This is particularly the case when a campaign of terror has specifically targeted family life and its traditions, when the culture is one whose identity has been centered in its families, and when public mental health resources have been scarce. At the end of the 1999 war in Kosova, the Kosovar Family Professional Educational Collaborative (KFPEC) was initiated to counter mental health sequelae of war in Kosova. This initiative focused upon the recovery and strengthening of Kosovar families, rather than the psychiatric treatment of individuals for post-traumatic symptoms. Findings and outcomes from this project may usefully inform the design of other international public mental health initiatives. 相似文献

Cotton-top tamarins (Saguinus oedipus) selected canes positioned so that a straight inward pull brought food within reach (M. D. Hauser, 1997; see also record 1997-41347-003). Tamarins failed to retrieve food with canes in other positions, and they did not reposition these canes. In this study, tufted capuchin monkeys (Cebus apella) preferred canes they could pull straight in when these were present, but they also repositioned canes in individually variable ways, and their success at obtaining food with repositioned canes improved with practice. In accord with predictions drawn from ecological psychology, capuchins discovered affordances of canes through exploratory actions with these objects, whereas tamarins did not. Ecological theory predicts these differences on the basis of species-typical manipulative activity, and it provides a useful approach for the study of species differences in tool-using behavior. 相似文献

The present study examined the relationship between the predictability of words within a sentence and the availability of
parafoveal word length information, on when and where the eyes move in reading. Predictability influenced first-pass reading
times when parafoveal word length preview information was correct, but not when it was incorrect. Similarly, for saccades
launched from near the target word (wordn), predictability influenced the probability with which it was skipped only when the word length preview was correct. By contrast,
for saccades launched farther away from wordn, predictability influenced word skipping regardless of the parafoveal word length preview. Taken together, the data suggest
that parafoveal word length preview and predictability can act as a joint constraint on the decision of when and where to
move the eyes. 相似文献

This study investigated the relationships among mindfulness, marital satisfaction, and perceived spousal similarity. All 95
subjects responded to a questionnaire measuring each of these variables, and an additional series of demographic variables.
A significant positive relationship was found between mindfulness and marital satisfaction, with no statistically significant
relationship found between perceived spousal similarity and marital satisfaction. There was a stronger correlation between
mindfulness and marital satisfaction than the correlation between marital satisfaction and any of the other variables, including
similarity. These results carry meaningful implications for the role of mindfulness techniques within the context of building
and maintaining happy marital relationships and general well-being. 相似文献

Animal models are considered essential in research ensuing elucidation of human disease processes and subsequently, testing of potential therapeutic strategies. This is especially true for neurodegenerative disorders, in which the first steps in pathogenesis are often not accessible in human patients. Alzheimer's disease is vastly becoming a major medical and socioeconomic problem in our aging society. Valid animal models for this uniquely human condition should exhibit histopathological, biochemical, cognitive, and behavioral alterations observed in Alzheimer's disease patients. Major progress has been made since the understanding of the genetic basis of Alzheimer's disease and the development and improvement of transgenic mouse models. All present Alzheimer's disease models developed are partial but nevertheless essential in further unraveling the nature and spatial and temporal development of the complex molecular pathology underlying this condition. One of the more recent transgenic attempts to model Alzheimer's disease is the APP23 transgenic mouse. This article describes the development and assessment of this human amyloid precursor protein overexpression model. We summarize histopathological and biochemical, cognitive and behavioral observations made in heterozygous APP23 mice, thereby emphasizing the model's contribution to clarification of neurodegenerative disease mechanisms. In addition, the first therapeutic interventions in the APP23 model are included. 相似文献

Mood-congruent attentional bias in dysphoria: maintained attention to and impaired disengagement from negative information 总被引:1,自引:0,他引:1
Attentional bias to negative information has been proposed to be a cognitive vulnerability factor for the development of depression. In 2 experiments, the authors examined mood-congruent attentional bias in dysphoria. In both experiments, dysphoric and nondysphoric participants performed an attentional task with negative, positive, and neutral word cues preceding a target. Targets appeared either at the same or at the opposite location of the cue. Overall, results indicate that dysphoric participants show maintained attention for negative words at longer stimulus presentations, which is probably caused by impaired attentional disengagement from negative words. Furthermore, nondysphoric participants maintain their attention more strongly to positive words. These results are discussed in relation to recent developments in the pathogenesis and treatment of depression. 相似文献

Intrusive reexperiencing in posttraumatic stress disorder (PTSD) has been linked to perceptual priming for trauma-related material. A prospective longitudinal study (N = 69) investigated perceptual priming for trauma-related, general threat, and neutral words in assault survivors with and without PTSD, using a new version of the word-stem completion task. Survivors with PTSD showed enhanced priming for trauma-related words. Furthermore, priming for trauma-related words measured soon after the trauma was associated with subsequent PTSD severity at 3, 6, and 9 months. The enhanced priming effect was specific to trauma-related words. Enhanced perceptual priming for traumatic material appears to be one of the cognitive processes operating in PTSD. 相似文献
