Podcasts offer a way for medical professionals to listen to current information in medicine from an iPod, MP3 player, handheld device, or computer. As podcasts become more popular, libraries may be interested in integrating programs into the library collection. South Pointe Medical Library evaluated medical podcasts relevant to the scope of the library collection and explored methods for finding and organizing such programs in ways that are efficient for both the librarian and the patron. doi:10.1300/J115v26n01_03.  相似文献

OBJECTIVE: The purpose of the current study was to investigate the independent effects of different treatment elements on a number of secondary problems related to childhood and adolescent sexual abuse, as well as investigate a number of different moderators of treatment effectiveness. METHOD: Twenty-eight studies that provided treatment outcome results for children and adolescents who had been sexually abused were included in the meta-analysis. Different aspects of psychological treatment, such as specific treatment modalities (individual, cognitive-behavioral, etc.) or secondary problems (behavior problems, psychological distress, etc.) were investigated. RESULTS: The overall mean weighted effect size for the meta-analysis was d=.72 (SE=.02). The results indicate that psychological treatment after childhood or adolescent sexual abuse tended to result in better outcomes than no treatment. There was significant heterogeneity in the effectiveness of the various psychological treatment elements. Play therapy seemed to be the most effective treatment for social functioning, whereas cognitive-behavioral, abuse-specific, and supportive therapy in either group or individual formats was most effective for behavior problems. Cognitive-behavioral, family, and individual therapy seemed to be the most effective for psychological distress, and abuse-specific, cognitive-behavioral, and group therapy appeared to be the most effective for low self-concept. CONCLUSIONS: The choice of therapy modality should depend on the child's main presenting secondary problem. Further research should be conducted investigating other possible moderators and secondary problem outcomes.  相似文献

OBJECTIVE: The aim was to examine how traumatic and stressful events, responses to violence, child characteristics, and mothering quality, as measured in middle childhood predict psychological distress and positive resources in adolescence. METHOD: The participants were 65 Palestinian adolescents (17+/-.85 years; 52% girls), who had been studied during the First Intifada (T1), during the Palestinian Authority rule (T2) and before the Second Al Aqsa Intifada (T3) in Gaza. Psychological distress was indicated by PTSD, and depressive symptoms and positive resources by resilient attitudes and satisfaction with quality of life, all measured at T3. The predictors that were measured at T1 were exposure to military violence, active coping with violence and children's intelligence, cognitive capacity, and neuroticism. Mothering quality and stressful life-events were measured at T2, the former reported by both the mother and the child, and the latter by the mother. RESULTS: Adolescents' PTSD symptoms were most likely if they had been exposed to high levels of traumatic and stressful experiences and had poor cognitive capacity and high neuroticism in middle childhood. Only high levels of childhood military violence and stressful life-events predicted high depressive symptoms and low satisfaction with quality of life in adolescence. CONCLUSIONS: Military violence in childhood forms risks for both increased psychological distress and decreased positive resources. However, child characteristics such as cognitive capacity and personality are important determinants of psychological vulnerability in military trauma.  相似文献

The purpose of this study was to compare the usefulness of the Bayley Scales of Infant Development (BSID)-Mental Scales and the Battelle Developmental Inventory (BDI) in assessing the abilities of infants and toddlers from teen-parent families. The 34 children lived with their mothers, who ranged in age from 15 to 21. The results of the study indicate that these two developmental instruments cannot be used interchangeably and that one needs to look beyond the psychometric data in order to understand the results of infant and toddler assessment. The correlation between the BSID-Mental Development Index (MDI) and BDI Total score was −.03.  相似文献

Objective:This study compared the recall and precision of MeSH-term versus text-word searching to better understand psychosocial MeSH terms and to provide guidance on whether to include both strategies in an information literacy session or how much time should be spent on teaching each search strategy.Methods:Using the relevant recall method, a total of 3,162 resources were considered and evaluated to form a gold standard set of 1,521 relevant resources. We compared resources discussing psychosocial aspects of children and adolescents living with type 1 diabetes using two search strategies: text-word strategy versus MeSH-term strategy. The frequency of MeSH terms, the MeSH hierarchy, and elements of each search strategy were also examined.Results:Using the 1,521 relevant articles, we found that the text-word search strategy had 54% recall, while the MeSH-term strategy had 75% recall. Also, the precision of the text-word strategy was 34.4%, while the precision of the MeSH-term strategy was 47.7%. Therefore, the MeSH-term search strategy yielded both greater recall and greater precision. The MeSH strategy was also more complicated in design and usage than the text-word strategy.Conclusions:This study demonstrates the effectiveness of text-word and MeSH search strategies on precision and recall. The combination of text-word and MeSH strategies is recommended to achieve the most comprehensive results. These results support the idea that MeSH or a similar controlled vocabulary should be taught to experienced and knowledgeable students and practitioners who require a myriad of resources for their literature searches.  相似文献
