Objective: Emotion regulation (ER) strategies are related to psychological health, with most work examining reappraisal and suppression. Yet, emerging findings suggest that rumination may have stronger relationships with psychological health, namely depression, than other ER strategies. This paper replicated and extended this work by testing whether rumination was independently associated with a range of poor psychological health risk indicators and outcomes. In addition, it explored whether the reason why rumination is so deleterious to health is because it underlies the stress–health relationship.

Design: Participants (n = 218) completed measures online.

Main outcome measures: Surveys assessed ER strategies (reappraisal, suppression, proactive coping, emotion support seeking, and rumination), health risk indicators (hostility, optimism, self-esteem), health outcomes (depression, poor sleep quality, anxiety) and perceived chronic stress.

Results: Multivariate regression analyses revealed rumination as the only ER strategy with a consistent independent effect on all the health risk indicators and outcomes. Bootstrapping analyses revealed indirect effects of perceived chronic stress on all the health variables via rumination.

Conclusion: Rumination had a deleterious relationship with psychological health, perhaps because rumination underlies the relationship between stress and psychological health. Results have implications for interventions, particularly emphasizing the need to target ruminative thinking after stressful experiences.  相似文献

Evidence-based intervention programs attuned to the spiritual needs of service members, Veterans, and their families are needed to help them deal with the potentially debilitating consequences of combat trauma. This study evaluated the effectiveness of a faith-based, peer-led combat trauma resiliency program called REBOOT Combat Recovery. Participants were 254 adults who reported on 8 aspects of physical, mental, and social well-being during the 3rd week and the 12th week of the program. Findings indicated improvement for pain interference, fatigue, sleep disturbance, anxiety and depressive symptoms, and social participation. Improvement was uniform except that Veterans benefited more than currently serving military personnel with respect to anxiety symptoms. These results suggest the program may be effective for coping with the aftermath of combat trauma.  相似文献

The relationship between firearm ownership and suicide is well documented. This study hypothesized that how soldiers store their firearms would moderate the relationship between suicidal ideation and the self-reported likelihood of engaging in a future suicide attempt, and that this relationship would be explained by fearlessness about death. There were 432 military personnel (91.3% men, 74.2% White, Mage = 27.60) who endorsed current ownership of a private firearm and who were recruited from a military base in the southeastern United States (94.5% National Guard). Firearm storage moderated the relationship between suicidal ideation and the self-reported likelihood of engaging in a future suicide attempt, but this relationship was not explained by fearlessness about death. Individuals who reported keeping their firearms loaded and stored in an unsecure location exhibited higher mean levels of fearlessness about death. Findings highlight the need for research examining contributors to suicide risk in the context of firearm storage, and provide support for suicide prevention efforts involving restricting means.  相似文献

Slower and more variable reaction times to computerized tasks have been documented in children diagnosed with attention deficit/hyperactivity disorder (ADHD). Recent research supports a role for attentional lapses in generating abnormally variable and slow responses. However, given the association between ADHD and impairments in motor control, we hypothesized that slower or more variable reaction times might also correlate with motor development. The aim of this case-control study was to explore the relationship between motor function, reaction speed and variability, and ADHD. After comprehensive educational and clinical assessments, motor skill development was evaluated in 35 children ages 9 to 14 (19 with ADHD) using the Physical and Neurological Examination for Subtle Signs (PANESS) test battery. Finger-sequencing speed and variability were quantified with goniometers. Reaction times were measured with 20 trials each of computerized simple and choice (binary) tasks. Compared to healthy controls, children with ADHD had slower and more variable reaction times, and these findings correlated with impaired motor development (PANESS) and slow and variable finger sequencing (goniometers). Further studies of motor development in ADHD may identify factors influencing speed and variability of reaction times.  相似文献

Abstract

Tissue engineering is one potential arm of the much-heralded regenerative medicine. We use the concepts of technological zone, risk framing and regulatory jurisdiction to analyse what risks are formulated in the zone of tissue engineering and whether those risks are reflected in emerging regulatory policy in Europe. In the regulatory jurisdictions of the European Union, public health risks have become increasingly important. Tissue engineering challenges pre-existing regulatory frameworks. Scientific–industrial actors formulate the risks of tissue engineering in three primary frames: technological safety risk; therapeutic efficacy risk; and economic risk. Study of the prevailing configuration of European Commission institutions and the EU process of regulatory regime-building for tissue engineering shows that risk frames are mobilized selectively. Whilst the technological safety frame and the economic frame are strongly mobilized, therapeutic efficacy—especially comparative efficacy—is not. Additionally the regime avoids any Europe-level position on the so-called ethics of sourcing and engineering tissues and cells. Efficacy and ethics are defined as the jurisdiction of national authorities, underpinned by the subsidiarity principle. Outcomes include the likely banning of certain therapeutic technologies by European countries that have objections to products deriving from controversial materials and processes, and the prevention of adoption of products due to efficacy concerns, so creating new imbalances in the European therapeutic marketplace. Consequently, the tissue-engineered medical products that European societies consume, at least in the near term, will reflect the medically defined needs of the European population to a limited and patchy extent.  相似文献

Despite much research on how interests are related to personality and creativity, comparatively little work has focused on how different college majors as categorized by the RIASEC model compare on these constructs. In this study, 3295 college students (207 Realistic, 1945 Investigative, 447 Artistic, 480 Social, and 216 Enterprising) completed a five-factor personality measure, a brief self-report of creativity, and the Compound Remote Associates Task (CRAT). Investigative and Artistic majors scored higher on openness and self-assessed creativity than Realistic and Social majors, and Investigative majors were much more agreeable than other majors.  相似文献

The purpose of this study was to examine the predictive value of PTSD symptoms and perceived relationship safety on dyadic adjustment. Participants included 390 individuals who were in a committed romantic relationship. Data were gathered from two populations; clients of a university-based family therapy clinic (n = 132), and community respondents to an announcement on a large university's electronic bulletin board (n = 258). Structural equation modeling was used to test a model of mediation, as well as multiple group analysis to test for moderation by setting (clinical vs. community) and gender. Results indicated that perceived relationship safety fully mediated the relationship between PTSD symptoms and dyadic adjustment. Gender moderated the relationships in the model, but no differences were found between the clinical and community samples. Findings suggest the importance of addressing experiences of safety and security in relationships, as these may be of particular importance for those who have experienced trauma.  相似文献

This paper presents the development and preliminary evaluation of a new word recognition test (WRT) designed to measure individual differences in mental flexibility, defined as the ability to solve novel problems in unfamiliar settings. Conceptually designed to simulate problem solving in real world performance situations, the test was developed to recruit fluid and reproductive abilities and the interplay between convergent and divergent thinking. It is based on a framework that integrates and extends previous theoretical and methodological approaches to the study of cognitive ability and creative cognition. The WRT was administered with various cognitive ability and criterion measures to an undergraduate student sample (n = 266). Results provide preliminary evidence of construct validity. WRT scores correlated as expected with reference measures of cognitive ability, creative performance, and college performance (GPA). Regression analyses showed the WRT explained an additional 4.5% of variance in college performance over and above traditional cognitive ability measures that take up to five times as long to administer. Results suggest further study is warranted given the potential for its contribution to basic research and applied use.  相似文献

The current studies explore how individual differences in personal need for structure (PNS) influence the extent to which people respond to terrorism threats with cultural worldview-related attitudinal rigidity. PNS was measured, terrorism salience manipulated, and British participants' attitudes toward an essay arguing against the British adoption of the Euro (Study 1) or American participants' attitudes toward an essay arguing for a nontraditional approach to the Thanksgiving meal (Study 2) were assessed. Terrorism salience, relative to a control condition, increased liking of the anti-Euro position and decreased liking for a nontraditional approach to Thanksgiving for those high in PNS. The reverse pattern was found for those low in PNS. Theoretical and applied implications are considered.  相似文献

People differ in their reactions to the outcomes of their group. Whereas some may revel in victory and mourn in defeat, others may internalize victory but distance themselves from defeat. Here, we sought to relate these divergent reactions to two forms of alignment with groups–identity fusion and group identification. Investigations of the 2008 elections in the United States and Spain revealed that people who were “fused” with their political party internalized both victory and defeat, but highly identified persons internalized only victory. We discuss how these findings bear on the conceptual distinctions between identity fusion and group identification.  相似文献
