Reduction of cancer‐related disparities requires strategies that link medically underserved communities to preventive care. In this community‐based participatory research project, a public library system brought together stakeholders to plan and undertake programs to address cancer screening and risk behavior. This study was implemented over 48 months in 20 large urban neighborhoods, selected to reach diverse communities disconnected from care. In each neighborhood, Cancer Action Councils were organized to conduct a comprehensive dynamic trial, an iterative process of program planning, implementation and evaluation. This process was phased into neighborhoods in random, stepped‐wedge sequence. Population‐level outcomes included self‐reported screening adherence and smoking cessation, based on street intercept interviews. Event‐history regressions (n = 9374) demonstrated that adherence outcomes were associated with program implementation, as were mediators such as awareness of screening programs and cancer information seeking. Findings varied by ethnicity, and were strongest among respondents born outside the U.S. or least engaged in care. This intervention impacted health behavior in diverse, underserved and vulnerable neighborhoods. It has been sustained as a routine library system program for several years after conclusion of grant support. In sum, participatory research with the public library system offers a flexible, scalable approach to reduce cancer health disparities.  相似文献

Ethical issues arise for genetic counselors when a client fails to disclose a genetic diagnosis of hereditary disease to family: they must consider the rights of the individual client to privacy and confidentiality as well as the rights of the family to know their genetic risk. Although considerable work has addressed issues of non-disclosure from the client’s perspective, there is a lack of qualitative research into how genetic counselors address this issue in practice. In this study, a qualitative approach was taken to investigate whether genetic counselors in Australia use a relational approach to encourage the disclosure of genetic information from hereditary breast and ovarian cancer (HBOC) clients among family members; and if so, how they use it. Semi-structured qualitative interviews were conducted with 16 genetic counselors from selected states across Australia. Data collection and analysis were guided by a basic iterative approach incorporating a hybrid methodology to thematic analysis. The findings provide indicative evidence of genetic counselors employing a relational approach in three escalating stages––covert, overt and authoritative––to encourage the disclosure of genetic information. The findings lend credence to the notion that genetic counselors envision a form of relational autonomy for their clients in the context of sharing genetic information, and they depart from individualistic conceptions of care/solely client-centered counseling when addressing the needs of other family members to know their genetic status.  相似文献

In this study, we examined the relationship between religiosity and attitudes towards professional mental health services. We further examined whether internal religious coping and external religious coping mediated both relationships. Results indicated a significant association with religiosity and negative attitudes towards mental health services, as well as external religious coping and internal religious coping. Results also showed a nonsignificant association with both religious coping and negative attitudes towards mental health services. Finally, external religious coping mediated the relationship between religiosity and negative attitudes towards mental health services for men but not for women.  相似文献

This study was designed to explore Black adolescent girls' gender roles, racial identity, and self-esteem. These variables have not been examined together in a study of Black girls, yet studies of girls from other racial/cultural groups have demonstrated significant relationships. This type of exploration is important because Black girls do not experience the same declines in self-esteem as girls from other racial/cultural groups. Gender role orientation and racial identity have been put forth as possible explanations for Black girls' bolstered levels of self-esteem. Results indicated that Black girls with androgynous and masculine characteristics reported high levels of self-esteem. The results also indicated that Black girls with internally defined Black racial identity attitudes reported high levels of domain-specific self-esteem. In addition, androgyny was associated with high scores on internalization (Black racial identity).  相似文献

Presentation of irrelevant additional information hampers learning. However, using a word-learning task, recent research demonstrated that an initial negative effect of mismatching pictures on learning no longer occurred once learners gained task experience. It is unclear, however, whether learners consciously suppressed attention to the content of the mismatching pictures. Therefore, we examined the effects of a picture location change towards the end of the learning phase: for half of the participants, the picture location was changed after they gained task experience. If participants only ignore the location of mismatching pictures, word learning in the mismatched condition should be hampered after the location change. Changing the location of the mismatching pictures did not affect recall in the mismatched condition, but, surprisingly, the location change did hamper learning in the matched condition. In sum, it seems that participants learned to ignore the content, and not just the location of the irrelevant information.  相似文献

This study examined associations between indices of the quality of attachment relationships of adolescents with parents and peers, rumination, and symptoms of depression. More specifically, a mediation model was investigated in which rumination was hypothesized to mediate the relation between quality of attachment relations and symptoms of depression. A total of 455 high school students completed a battery of questionnaires, including quality of attachment relations, rumination, and depression. Results showed that most indices of quality of attachment relations were significantly associated with rumination and symptoms of depression. When examining the relative contribution of these variables in explaining variance in depression symptoms, trust in parents, communication with peers, and alienation from peers accounted for a significant portion of the variance in depression scores. Finally, the relation between communication with peers and depressive symptoms was fully mediated by rumination, whereas partial mediation was found for the relations between parental trust and depressive symptoms, and between alienation from peers and depressive symptoms. Implications of the findings may be that the treatment of depression in adolescence should consist of both cognitive interventions aimed at targeting ruminative thinking as well as a focus on interpersonal relationships of the adolescent with parents and peers.  相似文献

Blinded by the accent! The minor role of looks in ethnic categorization   总被引:1,自引:0,他引:1  
The categories that social targets belong to are often activated automatically. Most studies investigating social categorization have used visual stimuli or verbal labels, whereas ethnolinguistic identity theory posits that language is an essential dimension of ethnic identity. Language should therefore be used for social categorization. In 2 experiments, using the "Who Said What?" paradigm, the authors investigated social categorization by using accents (auditory stimuli) and looks (visual stimuli) to indicate ethnicity, either separately or in combination. Given either looks or accents only, the authors demonstrated that ethnic categorization can be based on accents, and the authors found a similar degree of ethnic categorization by accents and looks. When ethnic cues of looks and accents were combined by creating cross categories, there was a clear predominance of accents as meaningful cues for categorization, as shown in the respective parameters of a multinomial model. The present findings are discussed with regard to the generalizability of findings using one channel of presentation (e.g., visual) and the asymmetry found with different presentation channels for the category ethnicity.  相似文献

Reasoning about legal cases is a complex skill that imposes a high working memory load, especially for novice students. Not only do novices lack necessary conceptual knowledge, searching through the information sources that are used during reasoning can also be assumed to impose a high additional working memory load that does not contribute to learning. Therefore, this study investigated the effects of supporting novice law students' learning by (a) providing the meaning of important concepts in the case and (b) reducing the search process by providing a condensed (relevant articles only) rather than a complete civil code. Results show that performance on a test case (for which they had to use the complete civil code) was significantly better for participants who had used the condensed civil code during learning. Performance on a conceptual knowledge post‐test was significantly enhanced when students had received the concept explanations during learning. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Previous demonstrations of asymmetrical scepticism (i.e., that investigators perceive evidence inconsistent [vs. consistent] with the focal hypothesis of a case as less reliable) have failed to account for the underlying mechanism. This study examined whether inconsistent evidence is discredited due to its inconsistency with a prior belief or because it conflicts with the goal to reach closure in a case. Police trainees (N = 107) were presented with a homicide case and judged the reliability of incriminating or exonerating evidence while entertaining a ‘guilty’ or ‘innocent’ hypothesis concerning a suspect. Asymmetrical scepticism was observed in the guilty condition, but not in the innocent condition, partially supporting the goal‐consistency explanation. Implications for the organization of criminal investigations are discussed. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Can listeners distinguish unfamiliar performers playing the same piece on the same instrument? Professional performers recorded two expressive and two inexpressive interpretations of a short organ piece. Nonmusicians and musicians listened to these recordings and grouped together excerpts they thought had been played by the same performer. Both musicians and nonmusicians performed significantly above chance. Expressive interpretations were sorted more accurately than inexpressive ones, indicating that musical individuality is communicated more efficiently through expressive performances. Furthermore, individual performers' consistency and distinctiveness with respect to expressive patterns were shown to be excellent predictors of categorisation accuracy. Categorisation accuracy was superior for prize-winning performers compared to non-winners, suggesting a link between performer competence and the communication of musical individuality. Finally, results indicate that temporal information is sufficient to enable performer recognition, a finding that has broader implications for research on the detection of identity cues.  相似文献
