New genetic tests reveal risks for multiple conditions simultaneously, although little is understood about the psychological factors that affect testing uptake. We assessed a conceptual model called the multiplex genetic testing model (MGTM) using structural equation modelling. The MGTM delineates worry, perceived severity, perceived risk, response efficacy and attitudes towards testing as predictors of intentions and behaviour. Participants were 270 healthy insured adults aged 25-40 from the Multiplex Initiative conducted within a health care system in Detroit, MI, USA. Participants were offered a genetic test that assessed risk for eight common health conditions. Confirmatory factor analysis revealed that worry, perceived risk and severity clustered into two disease domains: cancer or metabolic conditions. Only perceived severity of metabolic conditions was correlated with general response efficacy (β?=?0.13, p<0.05), which predicted general attitudes towards testing (β?=?0.24, p<0.01). Consistent with our hypothesised model, attitudes towards testing were the strongest predictors of intentions to undergo testing (β?=?0.49, p<0.01), which in turn predicted testing uptake (OR 17.7, β?=?0.97, p<0.01). The MGTM explained a striking 48% of the variance in intentions and 94% of the variation in uptake. These findings support use of the MGTM to explain psychological predictors of testing for multiple health conditions. 相似文献

Reports an error in "Do social networks explain 12-step sponsorship effects? A prospective lagged mediation analysis" by Kristina N. Rynes and J. Scott Tonigan (Psychology of Addictive Behaviors, Advanced Online Publication, Sep 5, 2011, np). There is an error in the last paragraph of the Participants section. It was reported that 14.8% of the sample were Asian, however, 14.8% of the participants were American Indian or Alaskan Native and no participants were Asian. (The following abstract of the original article appeared in record 2011-20052-001.) Sponsorship is a basic and important part of the 12-step approach to recovery from substance abuse (Alcoholics Anonymous, 2005) and research has shown that having a sponsor is associated with increased involvement in 12-step programs and improved outcomes (Bond, Kaskutas, & Weisner, 2003; Tonigan & Rice, 2010). However, little is known about how sponsorship improves outcomes. Given research demonstrating bivariate associations between sponsorship and social support for abstinence (Majer, Jason, Ferrari, Venable, & Olson, 2002), we hypothesized that the association between having a sponsor and increased abstinence outcomes would be explained by increases in one's abstinence-based social network. Prospective fully lagged mediational analyses did not support this hypothesis and these results ran counter to findings of five previous studies (cf. Groh, Jason, & Keys, 2008). A review of these studies showed that researchers often used cross-sectional or partially lagged methods to test mediation and the mediational effect of the social network was small in magnitude. Results suggest that the prospective association between sponsorship and abstinence is not explained by increases in the abstinence-based social network and demonstrate the need for future studies to use rigorous and time-lagged methods to test social support for abstinence as a mediator of the effects of 12-step involvement.

We used the take‐the‐best heuristic to develop a model to forecast the popular two‐party vote shares in U.S. presidential elections. The model draws upon information about how voters expect the candidates to deal with the most important issue facing the country. We used cross‐validation to calculate a total of 1000 out‐of‐sample forecasts, one for each of the last 100 days of the ten U.S. presidential elections from 1972 to 2008. Ninety‐seven per cent of forecasts correctly predicted the winner of the popular vote. The model forecasts were competitive compared to forecasts from methods that incorporate substantially more information (e.g., econometric models and the Iowa Electronic Markets). The purpose of the model is to provide fast advice on which issues candidates should stress in their campaign. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

There is increasing evidence to support the biological basis of mental disorders. Subsequently, understanding the neurobiological context from which mental distress arises can help counselors appropriately apply cognitive behavioral therapy and other well‐researched cognitive interventions. The purpose of this article is to describe the neurobiological context underlying the formation and treatment of posttraumatic stress disorders, a mental disorder frequently encountered by counselors, from a cognitive therapy framework. 相似文献

School counselors play a crucial role in the prevention, assessment, treatment, and overall management of eating‐related problems among children and adolescents. This article provides a framework for conceptualizing these difficulties on a continuum of severity and includes recommendations at each level for intervention and consultation. Collaboration with other professionals is encouraged when confronted with these multifaceted issues. Efforts by school counselors are vital to prevention and recovery from eating disorders. 相似文献

National surveillance data indicate marked differences between Indigenous and other Australians in the prevalence of many sexually transmitted infections (STIs). Young Indigenous people bear a particularly high burden of these infections. A collaboration of university researchers, Indigenous health workers and young Indigenous people conducted 45 field interviews to examine how young Indigenous Australians keep themselves healthy and protected against STIs. Our findings emphasise the complexity of health behaviours, where individuals are rarely always ‘risky’ or always ‘safe’, as well as subtle gender differences in health practices. Preventive strategies employed by the young people were contingent on beliefs and knowledge about sexual partners, the type of relationship, the context of the sexual encounter and access to condoms. Tangible strengths such as young Indigenous people's commitments to condoms and STI screening should be celebrated and bolstered to enhance their ability to protect themselves against adverse health outcomes and enhance their resilience against STIs. Focusing on strengths helps to counter the deficit model of health commonly deployed in Indigenous health research and draws attention to health issues facing young Indigenous people and their communities, without reinforcing negative stereotypes or focusing solely on individual risk behaviour. We provide concrete recommendations for health promotion and education. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

This study examined interventions for addition and subtraction that were implemented through single-case design (SCD) research studies. We attempted to extend prior SCD meta-analyses by examining differences in effect sizes across several moderating variables and by including a novel index of effect, improvement rate difference (IRD). We also examined the extent to which effect sizes differed by degree of experimental control achieved in the studies. Forty-seven effect sizes were obtained across 11 studies. IRD effect sizes ranged from .59 to .90 and suggested a moderate to large effect for the math interventions. Variables that appeared to moderate the effects were student age, time spent in intervention, and intervention type. We also identified a relationship between experimental control and the obtained effect sizes. Findings indicated that further SCD research in basic arithmetic and rigorous experiments are necessary to establish an evidence base that accurately characterizes intervention effectiveness. 相似文献

Using self-report as a measure of conscious experience has been a point of contention in mind wandering research. Whereas prior work has focused on the introspective component of self-report validity, the current research introduces an honesty prime task to the current paradigm in order to assess the role of goal states and social factors on self-report accuracy. Findings provide evidence for an inflated report of mind wandering frequency arising from demand characteristics, intensified by the divergent properties of the subjective and behavioural measures and the general deficit in meta-awareness of off task episodes. 相似文献

An increasing number of genetic counselors are moving into non-clinical roles, where their primary duties do not involve direct patient contact. According to the National Society of Genetic Counselors Professional Status Survey in 2010, 23% of counselors working in non-clinical roles identified laboratory or genetic testing as their primary area of work. Using a survey, we identified 43 genetic counselors who work predominately in laboratory settings. The two primary tasks performed by participants, include acting as a customer liaison (95%) and calling out test results (88%). Nineteen participants (44.2%) also reported spending a considerable amount of time signing reports. The most prevalent areas of job satisfaction were support from laboratory directors (76.8%), autonomy (76.7%), interactions with clinicians (69.7%) and interaction with other genetics counselors (67.5%). This is the first study specifically looking at the roles of laboratory genetic counselors, which is an expanding area of genetic counseling. 相似文献

To examine the association of 1) race/ethnicity and 2) numeracy with awareness of DTC genetic tests. Secondary analysis of
6,754 Hispanic, black, and white adult respondents to the National Cancer Institute’s 2007 Health Information National Trends
Survey (HINTS). Logistic regression was used to examine sociodemographic predictors of DTC genetic tests awareness including
race/ethnicity, income, education, and gender. Next, two numeracy variables were added to the model. After controlling for
sociodemographic variables, black respondents were significantly less likely to have heard of DTC genetic tests compared to
white respondents (OR = 0.79; CI: 0.65–0.97). When numeracy variables were added to the model, the effect of black race was
no longer significant (OR = 0.84; CI: 0.69–1.04). Hispanic respondents did not significantly differ from white respondents
in awareness of DTC genetic tests. Other significant correlates of DTC genetic tests awareness in the full model included
education, income, age, and numeracy variables including degree to which people use medical statistics and numbers to make
health decisions, and preference for words or numbers when discussing “the chance of something happening.” Although black
respondents were generally less aware of DTC genetic tests than white respondents, this relationship appears to be partially
mediated by numeracy. 相似文献
