Objective:The aim of this project was to validate search filters for systematic reviews, intervention studies, and observational studies translated from Ovid MEDLINE and Embase syntax and used for searches in PubMed and Embase.com during the development of evidence summaries supporting first aid guidelines. We aimed to achieve a balance among recall, specificity, precision, and number needed to read (NNR).Methods:Reference gold standards were constructed per study type derived from existing evidence summaries. Search filter performance was assessed through retrospective searches and measurement of relative recall, specificity, precision, and NNR when using the translated search filters. Where necessary, search filters were optimized. Adapted filters were validated in separate validation gold standards.Results:Search filters for systematic reviews and observational studies reached recall of ≥85% in both PubMed and Embase. Corresponding specificities for systematic review filters were ≥96% in both databases, with a precision of 9.7% (NNR 10) in PubMed and 5.4% (NNR 19) in Embase. For observational study filters, specificity, precision, and NNR were 68%, 2%, and 51 in PubMed and 47%, 0.8%, and 123 in Embase, respectively. These filters were considered sufficiently effective. Search filters for intervention studies reached a recall of 85% and 83% in PubMed and Embase, respectively. Optimization led to recall of ≥95% with specificity, precision, and NNR of 49%, 1.3%, and 79 in PubMed and 56%, 0.74%, and 136 in Embase, respectively.Conclusions:We report validated filters to search for systematic reviews, observational studies, and intervention studies in guideline projects in PubMed and Embase.com.  相似文献

Objective:This study was intended to (1) provide clinical trial data-sharing platform designers with insight into users'' experiences when attempting to evaluate and access datasets, (2) spark conversations about improving the transparency and discoverability of clinical trial data, and (3) provide a partial view of the current information-sharing landscape for clinical trials.Methods:We evaluated preview information provided for 10 datasets in each of 7 clinical trial data-sharing platforms between February and April 2019. Specifically, we evaluated the platforms in terms of the extent to which we found (1) preview information about the dataset, (2) trial information on ClinicalTrials.gov and other external websites, and (3) evidence of the existence of trial protocols and data dictionaries.Results:All seven platforms provided data previews. Three platforms provided information on data file format (e.g., CSV, SAS file). Three allowed batch downloads of datasets (i.e., downloading multiple datasets with a single request), whereas four required separate requests for each dataset. All but one platform linked to ClinicalTrials.gov records, but only one platform had ClinicalTrails.gov records that linked back to the platform. Three platforms consistently linked to external websites and primary publications. Four platforms provided evidence of the presence of a protocol, and six platforms provided evidence of the presence of data dictionaries.Conclusions:More work is needed to improve the discoverability, transparency, and utility of information on clinical trial data-sharing platforms. Increasing the amount of dataset preview information available to users could considerably improve the discoverability and utility of clinical trial data.  相似文献

Background:The COVID-19 pandemic has sparked a wave of SARS-CoV-2 and COVID-19 research that organizations around the world have been synthesizing in evidence reviews to provide high-quality evidence to support policymakers and clinicians. The urgency of these efforts opens these organizations to the risk of duplicated efforts, which could waste valuable time and resources.Case Presentation:The VA Evidence Synthesis Program (VA ESP) formed a COVID Response Team that launched an online catalog of COVID-19 evidence reviews in March 2020 (https://www.covid19reviews.org/). The goal of this website is to capture the work of evidence synthesis groups in the US and around the world to maximize their collective contributions to patients, frontline clinicians, researchers, and policymakers during the COVID-19 pandemic and avoid duplicating efforts.Conclusions:This ongoing and evolving project provides a helpful catalog of evidence reviews at various stages of production; in addition, the website provides further value with informational icons, review collections, and links to similar resources. The VA ESP will maintain this website to continue to support the needs of policymakers, clinicians, and researchers both within the VA and around the world throughout the COVID-19 pandemic.  相似文献

Two studies are utilized to test a revised version of Guerrero, Andersen, Eloy, Spitzberg, and Jorgensen's (1995 Guerrero, L. K., Andersen, P. A., Jorgensen, P. F., Spitzberg, B. H. and Eloy, S. V. 1995. Coping with the green-eyed monster: Conceptualizing and measuring communicative responses to romantic jealousy. Western Journal of Communication, 59: 270304. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) communicative responses to jealousy (CRJ) scale and examine how measures from the CRJ associate with relational satisfaction. Study 1 uses exploratory factor analysis to identify a preliminary factor structure. Study 2 uses confirmatory factor analysis to determine whether this factor structure holds across a second sample, as well as structural equation modeling to test hypotheses regarding the associations between communicative responses to jealousy and relational satisfaction. These studies suggest that there are 11 specific communicative responses to jealousy that fall under four superordinate categories: (a) destructive communication, which consists of negative communication, counter-jealousy induction, and violence; (b) constructive communication, which includes integrative communication and compensatory restoration; (c) avoidance, which comprises silence and denial; and (d) rival-focused communication, which includes signs of possession, surveillance, rival contacts, and derogation of the rival. Destructive communication and, to a lesser extent, rival-focused communication associated negatively with relational satisfaction, whereas constructive communication associated positively. Recommendations for using the CRJ scale in future studies are provided.  相似文献

Recently, the margins between gaming and feminism have become increasingly contentious (Salter & Blodgett, 2012 Salter, A., & Blodgett, B. (2012). Hypermasculinity & Dickwolves: The contentious role of women in the new gaming public. Journal of Broadcasting & Electronic Media, 56, 401416. doi:10.1080/08838151.2012.705199[Taylor & Francis Online], [Web of Science ®] [Google Scholar]). This article addresses a cultural moment where masculine gaming culture became aware of and began responding to feminist game scholars by analyzing GamerGate conspiracy documents and social media discussions related to the now infamous “DiGRA fishbowl.” Worries about the opacity of academic practices and a disparaging of feminist knowledge-making practices dominate these documents. By looking at these discussions and practices through the lens of conspiracy theories (Fenster, 2008 Fenster, M. (2008). Conspiracy theories: Secrecy and power in American culture (2nd edition). Minneapolis, MN: University of Minnesota Press. [Google Scholar]; Hofstadter, 1952 Hofstadter, R. (1952). The paranoid style in American politics and other essays. Cambridge, MA: Harvard University Press. [Google Scholar]) and counterknowledge (Fiske, 1994 Fiske, J. (1994). Blackstream knowledge: Genocide. In Media matters: Everyday culture and political change. Minneapolis, MN: University of Minnesota Press. [Google Scholar]) we consider the broader meaning of GamerGate's attention to academia.  相似文献

The purpose of this investigation is to apply Gold's (1989 Gold, D. T. (1989). Sibling relationships in old age: A typology. International Journal of Aging and Human Development, 28, 3751.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) typology of sibling relationships to the study of adult-sibling use of relational maintenance behaviors and perceptions of relational characteristics. Participants were 196 adults who targeted a sibling whose birthday was closest to their own and completed a series of instruments in reference to the targeted sibling. It was found that whether individuals classified their sibling relationships as intimate, congenial, loyal, or apathetic/hostile was reflected in their self-reported use of relational maintenance behaviors, their perceptions of their targeted siblings' use of relational maintenance behaviors with them, and their perceptions of the relational characteristics associated with the sibling relationship.  相似文献

This report is a validity study involving the Cognitive Flexibility Scale (Martin & Rubin, 1995 Martin , M. M. , & Rubin , R. B. ( 1995 ). A new measure of cognitive flexibility . Psychological Reports , 76 , 623626 .[Crossref], [Web of Science ®] [Google Scholar]). Participants completed an online questionnaire. As predicted, cognitive flexibility was positively related to measures of intellectual flexibility and self-compassion, and negatively related to a measure of dogmatism. The prediction that cognitive flexibility would be negatively related to preference for consistency was not supported.  相似文献

More than 60% of college students admit to trying smoking (Rigotti, Lee, & Wechsler, 2000 Rigotti , N. , Lee , J. E. , & Wechsler , H. ( 2000 ). U.S. college students' use of tobacco products: Results of a national survey . Journal of the American Medical Association , 284 , 699706 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). To reduce this number, researchers have attempted to determine factors influencing smoking behaviors. However, studies about communicative acts related to smoking intentions and behaviors, which may be factors, are lacking. Guided by the Theory of Planned Behavior, this study hypothesized that attitudes, subjective norms, and perceived behavioral control regarding communicating about smoking would be positively associated with behavioral intentions to engage in such communication. It was found that students' attitudes toward communicating about smoking were positively associated with behavioral intention, but perceived behavioral control and subjective norms concerning smoking-related communication behaviors were not associated with behavioral intention.  相似文献

This study investigated whether and how exposure to tanned images on television is related to tanning attitudes and intentions among men and women, using the influence of presumed influence model (Gunther & Storey, 2003 Gunther , A. C. , & Storey , J. D. ( 2003 ). The Influence of presumed influence . Journal of Communication , 53 , 199215 .[Crossref], [Web of Science ®] [Google Scholar]). The model showed a better fit with the male rather than female sample. In addition, among males, exposure to tanned-men images on television was directly associated with protanning attitudes and was indirectly associated with protanning intentions. Corresponding direct and indirect associations were not found among females. Instead, the results suggest females may project their own protanning intentions into the estimation of protanning norms among male and female peers. These results suggest the social perceptual processes underlying the link between television exposure and tanning tendencies of men and women may differ.  相似文献
