We assess the predictive and discriminant validity of the basic values in the refined Schwartz value theory by examining how value tradeoffs predict behavior in Italy, Poland, Russia, and the USA. One thousand eight hundred and fifty‐seven respondents reported their values and rated their own and a partner's behavior. Multigroup confirmatory factor analysis supported the distinctiveness of the 19 values and the 19 self‐rated and other‐rated behaviors. Multidimensional scaling analyses supported the circular motivational order of the 19 values. Findings affirmed the theorizing that behavior depends upon tradeoffs between values that propel and values that inhibit it. Across four countries, value importance, behavior frequency, and gender failed to moderate the strength of value–behavior relations. This raises the question of the conditions under which the widely cited assumption that normative pressure weakens value–behavior relations holds.  相似文献

The most rigorous research on the causal effects of assisted housing on children's outcomes finds no such effects. The present study uses rich longitudinal data from the Panel Study of Income Dynamics, augmented with Census, American Community Survey and U.S. Department of Housing and Urban Development administrative data, to unpack these nil effects. Analyses include 194 children ( age = 6.2 years) living in assisted housing in 1995 or later who were 13–17 years old in 2002 or 2007, and an unassisted comparison group of 215 children who were income‐eligible for, but never received, housing assistance. Results suggested no mean effects of living in assisted housing during childhood on adolescent cognitive, behavior, and health outcomes, addressing selection through propensity score matching and instrumental variables. However, quantile regressions suggest assisted housing provides an added boost for children with the best cognitive performance and fewest behavior problems but has opposite effects on children with the lowest cognitive scores and most behavior problems. Further tests indicate that these differences are not explained either by neighborhood effects or housing quality. A potentially fruitful avenue for future research investigates differences in how parents take advantage of the housing affordability provided by assisted housing to benefit their children.  相似文献

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

Peer interaction has been found to be conducive to learning in many settings. Knowledge co‐construction (KCC) has been proposed as one explanatory mechanism. However, KCC is a theoretical construct that is too abstract to guide the development of instructional software that can support peer interaction. In this study, we present an extensive analysis of a corpus of peer dialogs that we collected in the domain of introductory Computer Science. We show that the notion of task initiative shifts correlates with both KCC and learning. Speakers take task initiative when they contribute new content that advances problem solving and that is not invited by their partner; if initiative shifts between the partners, it indicates they both contribute to problem solving. We found that task initiative shifts occur more frequently within KCC episodes than outside. In addition, task initiative shifts within KCC episodes correlate with learning for low pre‐testers, and total task initiative shifts correlate with learning for high pre‐testers. As recognizing task initiative shifts does not require as much deep knowledge as recognizing KCC, task initiative shifts as an indicator of productive collaboration are potentially easier to model in instructional software that simulates a peer.  相似文献

Cognitive Behavioral Therapy (CBT), Rational Emotive Behavior Therapy (REBT) and Metacognitive Therapy (MCT) models show both similarities and differences in conceptualizing anxiety. This work assumes that REBT’s irrational and MCT’s metacognitive beliefs play a mediation role while CBT’s disorder specific content beliefs act as triggers. This hypothesis is tested using a regression model in which metacognitive and irrational beliefs play a mediation role while content disorder beliefs are independent variables. This paper applied this model to generalized anxiety disorder (GAD), a psychiatric diagnosis in which anxiety is the major feature. In GAD, the specific content beliefs are negative problem orientation and intolerance of uncertainty. Therefore, 149 non clinical subjects completed 4 self-report questionnaires: the Negative Orientation to the Problems Questionnaire and the Intolerance of Uncertainty Scale as measures for content cognitive beliefs, the Attitudes and Beliefs Scale for irrational beliefs, and the Metacognitive Questionnaire 30 Items Version for metacognitive beliefs. The generalized anxiety disorder questionnaire was chosen in order to measure anxiety as dependent variable. Regression analyses confirmed that irrational and metacognitive beliefs mediate the relation between cognitive content beliefs and GAD. We clinically interpret mediation as a second level regulation.  相似文献

This paper describes my struggle to retain my personal and professional identity while undergoing treatment for breast cancer. It would have been easy to slip into being “the tumor in the left breast.” A circumscribed writing project helped, since writing has always been part of my life. Some interactions with patients in treatment were also crucial to my sense of ongoing personhood.  相似文献

Attention deficit hyperactive disorder (ADHD) is associated with elevated levels of substance abuse, but the cognitive linkages involved have been little explored. The present study builds upon earlier work showing that more gestalt, as opposed to feature-intensive, styles of processing are conductive to substance abuse, especially in those with ADHD symptoms. The work reported here indicates that a protective factor against substance abuse may lie in relatively efficient heuristic processing, especially synthetic or inferential heuristic processing, but further demonstrates that those with ADHD symptoms tend to have poorer abilities in this regard, even at the subclinical, nondiagnosed level. Results are discussed in terms of the gestalt/featureintensive processing theory of cognition.  相似文献
