The purpose of this study was to examine the impact of a peer-leadership training program on youth from a low-income urban school district. The methodological approach was grounded in community-based participatory research, in which a multicomponent school-based recess and physical activity program was examined. Data included 15 focus groups conducted with 77 fourth- and fifth-grade participants and semistructured interviews with 13 adult leaders. Results of a thematic content analysis suggest that decisions to join the program, role expectations, and training received impacted leadership development, personal development, and transfer of skills to other domains.  相似文献

A 6‐year‐old boy with autism spectrum disorder engaged in automatically maintained stereotypy in the form of opening and closing doors. A functional analysis confirmed that he also emitted problem behavior that was maintained by access to stereotypy. We evaluated the separate and combined effects of functional communication training and arbitrary noncontingent reinforcement on both response classes. Results showed that the combination of functional communication training and noncontingent reinforcement was more effective at reducing stereotypy than either intervention on its own, although effects on problem behavior were unclear. These results suggest that combinations of interventions may be useful in the treatment of automatically maintained problem behavior.  相似文献

This research examined the hypothesis that reduced posterior right hemisphere activity interferes with the regulation of emotions and behaviour in response to stress, creating vulnerability to depression. Consistent with a diathesis–stress model, we predicted that youths with a reduced posterior right hemisphere bias in emotional processing would engage in less adaptive responses to stress, which would be associated with depressive symptoms in those who reported the recent experience of high, but not low, levels of stress. Participants were 510 4th through 8th graders who completed the Chimeric Faces Task and measures of responses to stress and depressive symptoms. Results supported the idea that responses to stress account for the association between reduced posterior right hemisphere activity and depressive symptoms in youths who report high, but not low, levels of stress. This study provides insight into one process through which reduced posterior right hemisphere activity may confer vulnerability to depressive symptoms, and implicates responses to stress as a target for intervention.  相似文献

Survivors of lung or head and neck cancers often change tobacco and alcohol consumption after diagnosis, but few studies have examined other positive health changes (PHCs) or their determinants in these groups. The present study aims to: (a) document PHCs in survivors of lung (n?=?107) or head and neck cancers (n?=?99) and (b) examine behavioural self-blame and stigma as determinants of PHCs. We hypothesised that: (a) survivors would make a variety of PHCs; (b) behavioural self-blame for the disease would positively predict making PHCs; and (c) stigma would negatively predict making PHCs.

Methods: Respondents self-administered measures of PHC, behavioural self-blame, and stigma. Hierarchical multiple regression analysis tested the hypotheses.

Results: More than 65% of respondents reported making PHCs, the most common being changes in diet (25%), exercise (23%) and tobacco consumption (16.5%). Behavioural self-blame significantly predicted PHCs but stigma did not. However, both behavioural self-blame and stigma significantly predicted changes in tobacco consumption.

Conclusions: Many survivors of lung or head and neck cancers engage in PHCs, but those who do not attribute the disease to their behaviour are less likely to do so. Attention to this problem and additional counselling may help people to adopt PHCs.  相似文献

Over the past three decades, perinatal HIV infection in the United States has evolved from a fatal disease to a manageable chronic illness. As the majority of youth with perinatal HIV infection age into adolescence and adulthood, management of this stigmatizing, transmittable disease in the backdrop of a cadre of environmental stressors presents challenges beyond those of other chronic illnesses. The neurologic and neuropsychological consequences of this neurotropic virus have important implications for the successful navigation of responsibilities related to increasingly independent living of this aging population. This article will review the neurologic and neuropsychological consequences of perinatal HIV infection and concomitant factors in the era of highly active antiretroviral therapy and will provide an overview of the neuropathology, pathogenesis, neuroimaging findings, and treatment of perinatal HIV infection, as well as recommendations for service provision and future research.  相似文献

Children may be prepared to associate adult disgust reactions with adult disgust elicitors. To test this, three-year olds (and adults) were presented with two images and an emotive vocalization. The images and vocalizations included stimuli adults found disgusting, fear-provoking, and sad. On one set of trials, the main dependent variable (DV) was time spent looking at each image and on a second set of repeat trials the DV was knowledge of image-sound matches. Fear and disgust vocalizations were both more effective at orienting a child's attention to adult fear and disgust images, than sad vocalizations. Parental disgust sensitivity was associated with this effect, moderated by explicit matching knowledge. Matching knowledge was poor in children and good in adults. These data suggest that in children, fear and disgust vocalizations may both promote attention to stimuli that adults find disgusting and/or fear-provoking, suggesting that “preparedness” may not be wholly emotion-specific.  相似文献
