As increasing numbers of people are identified at risk for multi-factorial diseases, questions of how to assess, communicate and manage genetic risk will be critical from health services and policy perspectives. However, there is currently no evidence-based genetic risk assessment and management framework to assist policy makers, clinicians and other stakeholders. A comprehensive psychosocial framework for risk assessment and management has been developed in the context of security hazards or threats. In an adaptation of that model, we present the Psychosocial Genetics Risk Assessment and Management framework (PG-RAM). It offers principles to enhance the integration of evidence-based best practices into genetics health services, as well as to identify issues, knowledge and gaps. The framework identifies the core elements of the situation, effects, population and interventions, all spanning several phases of genetic disorders. The framework provides an excellent starting point for knowledge syntheses in the context of genetic risk and could serve as the conceptual basis for practical tool development to guide healthcare professionals and decision makers in preparing for and responding to the psychosocial aspects of genetic risk.  相似文献

This study examined the attributions made by school counselors about responsibility for the causes of and solutions to students' problems. A total of 433 school counselors completed an instrument measuring attributions of responsibility and controllability of student problems. The hypothesis was supported that school counselors' attribution styles differ according to counselor ethnicity. Este estudio examinó las atribuciones hechas por consejeros de escuela acerca de responsabilidad para las causas de y de las soluciones a los problemas de los estudiantes. Un suma de 433 consejeros de la escuela completó un instrumento que mide atribuciones de responsabilidad y la habilidad de controlar los problemas de los estudiantes. La hipótesis se sostuvo que los estilos de atribución de los consejeros de escuela se difieren según el origin étnico del consejero.  相似文献

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.  相似文献

Seventy-four European American women aged 50-68 years completed surveys of menopausal attitudes, appearance aging anxiety, body esteem, body surveillance, and body shame. Hypotheses based on the connections between cultural constructions of femininity and menopause were partially supported. Menopausal attitudes and appearance-related aging anxiety were related to body surveillance. Appearance-related menopausal attitudes were related to both body surveillance and body esteem. Body shame moderated the relationship between appearance-related menopausal attitudes and body esteem.  相似文献

Happiness is generally considered an emotion with only beneficial effects, particularly in childhood. However, there are some situations where the style of information processing triggered by happiness could be a liability. In particular, happiness seems to motivate a top-down processing style, which could impair performance when attention to detail is required. Indeed, in Experiment 1, 10- to 11-year-old children (N = 30) induced to feel a happy mood were slower to locate a simple shape embedded in a complex figure than those induced to feel a sad mood. In Experiment 2, 6- to 7-year-old children (N = 61) induced to feel a happy mood found fewer embedded shapes than those induced to feel a sad or neutral mood. Happiness may have unintended and possibly undesirable cognitive consequences, even in childhood.  相似文献

Disordered eating is linked to body shapes and images presented in the mass media. Favored celebrities may represent a particularly strong source of influence. We examined cross-sectional relationships between women's disordered eating and their perceptions of body-shape differences with favored celebrities. Women between the ages of 18 and 27 rated personal body shapes alongside those of self-selected favored celebrities. Multivariate analyses showed self/celebrity body-shape discrepancies to be linked to EAT-26 diet, bulimia, and oral control scales independent of personal body-shape and self/ideal discrepancies. For bulimia subscale scores, this relationship was moderated by a more favorable perception of the celebrity relative to the self. Celebrities might be important in creating an unrealistic social comparison standard that contributes to disordered eating.  相似文献

The relationship between rapid automatized naming (RAN) and reading fluency is well documented (see Wolf, M. & Bowers, P.G. (1999). The double-deficit hypothesis for the developmental dyslexias. Journal of Educational Psychology, 91(3), 415–438, for a review), but little is known about which component processes are important in RAN, and why developmental dyslexics show longer latencies on these tasks. Researchers disagree as to whether these delays are caused by impaired phonological processing or whether extra-phonological processes also play a role (e.g., Clarke, P., Hulme, C., & Snowling, M. (2005). Individual differences in RAN and reading: A response timing analysis. Journal of Research in Reading, 28(2), 73–86; Wolf, M., Bowers, P.G., & Biddle, K. (2000). Naming-speed processes, timing, and reading: A conceptual review. Journal of learning disabilities, 33(4), 387–407). We conducted an eye-tracking study that manipulated phonological and visual information (as representative of extra-phonological processes) in RAN. Results from linear mixed (LME) effects analyses showed that both phonological and visual processes influence naming-speed for both dyslexic and non-dyslexic groups, but the influence on dyslexic readers is greater. Moreover, dyslexic readers’ difficulties in these domains primarily emerge in a measure that explicitly includes the production phase of naming. This study elucidates processes underpinning RAN performance in non-dyslexic readers and pinpoints areas of difficulty for dyslexic readers. We discuss these findings with reference to phonological and extra-phonological hypotheses of naming-speed deficits.  相似文献

The authors of the theory of reasoned action (TRA) and its extension, the theory of planned behaviour (TPB) recommend that researchers who use these theories to investigate the determinants of a given behaviour should first conduct an elicitation study to identify the modal salient beliefs in the target population. In spite of the importance accorded to salient beliefs by the TRA/TPB, the elicitation stage has received little research attention. This paper reports a detailed analysis of beliefs about “being more physically active in the next 12 months.” A general population sample of 213 adults completed a questionnaire while attending a research centre for a series of tests. The findings showed that the beliefs that were elicited by questions designed to prompt affective outcomes (like or enjoy, dislike or hate) differed systematically from those that were elicited by the traditional questions designed to prompt instrumental out-comes (advantages and disadvantages). Whether this resulted in different final sets of modal salient beliefs was found to depend on the particular decision rule that was employed. An alternative decision rule is proposed, based on maximizing the degree of overlap between the modal set and the full set of salient beliefs generated by the sample. The index of overlap can be used to gauge the adequacy of using a modal set of a given size to represent the salient beliefs of the whole sample. In the current dataset, the optimal modal set for “advantages and disadvantages” was associated with only 26 percent overlap with the salient beliefs of the whole sample, which was judged to be insufficient. In such cases, a better strategy may be to ask participants to generate and rate their own beliefs.  相似文献
