对891位网民问卷调查分析,探讨了网民的情绪敏感度、集群行为意向和执行意向的关系。结果显示情绪敏感度与感知一致性、行为意向和执行意向均存在显著正向关联;情绪敏感度、感知一致性和行为意向三个变量的交互作用对执行意向的影响是显著的,进一步的研究发现在低感知一致性组中,情绪敏感度在行为意向对执行意向的影响中存在调节作用,具体表现为与低情绪敏感度的网民相比,当高情绪敏感度的网民感知到信息与行为的不一致结果时,行为意向对其执行意向的预测作用更强。     

Experimental Tests of Risk Ladders in the Elicitation of Perceived Likelihood

Risk ladders have the potential to improve numeric judgments of low‐likelihood events by providing information about the likelihoods of comparison risks, thereby letting respondents make risk estimates “in context.” However, to date this tool has been studied systematically only in communication of risk, not in elicitation of perceived likelihoods. In three studies, we evaluated the benefits of risk ladders on the consistency, validity, and mean‐level accuracy of elicited likelihood judgments. When estimates for low‐likelihood hazards were elicited using different numeric response scales (e.g., “1 in x” and “x in 100,000”), scale type had a strong effect on the magnitudes of the elicited estimates, and viewing a risk ladder (Experiment 1) or comparison risks (Experiments 2 and 3) did not attenuate this effect of scale type. Similarly, we found no evidence that risk ladders or comparison risks improved the convergent validity of numeric estimates, as measured using correlations with risk ratings made on alternative scale types. Finally, viewing comparison risks tended to reduce gross overestimation of rare events, with relatively less change in estimates for mid‐likelihood and high‐likelihood hazards. This suggests that comparison risks can spread responses to cover a wider range of values but do not ameliorate scale effects. In the elicitation of numeric risk estimates, how you ask matters, even if you let people make estimates “in context” through the use of comparative risk information.

Work Context Support and Portuguese Soldiers’ Well-Being: The Mediating Role of Autonomous Motivation

Using self-determination theory ( Deci & Ryan, 2008 Deci, E. L., & Ryan, R. M. (2008). Self-determination theory: A macrotheory of human motivation, development, and health. Canadian Psychology, 49, 182–185. 10.1037/a0012801[Crossref], [Web of Science ®] , [Google Scholar]) as the theoretical framework, we tested a model for this study that considers soldiers’ perceptions of organizational support and leader–member exchange (LMX), work motivation, and well-being at work. The hypothesized model was tested using a representative sample of 1,045 Portuguese soldiers. Results revealed that autonomous work motivation was significantly related to both contextual factors (organizational support and LMX). In addition, autonomous work motivation was positively related to work engagement and negatively related to burnout, and controlled motivation showed the opposite pattern. More interesting, the results showed that autonomous work motivation as a mechanism that helped to explain the relationship between both contextual factors and workplace well-being. The present results underscore the importance of understanding the mechanisms through which higher work engagement and lower burnout take place, eventually leading to appropriate interventions.     

Ethics Consultation in Pediatrics: Long-Term Experience From a Pediatric Oncology Center

There is little information about the content of ethics consultations (EC) in pediatrics. We sought to describe the reasons for consultation and ethical principles addressed during EC in pediatrics through retrospective review and directed content analysis of EC records (2000–2011) at St. Jude Children's Research Hospital. Patient-based EC were highly complex and often involved evaluation of parental decision making, particularly consideration of the risks and benefits of a proposed medical intervention, and the physician's fiduciary responsibility to the patient. Nonpatient consultations provided guidance in the development of institutional policies that would broadly affect patients and families. This is one of the few existing reviews of the content of pediatric EC and indicates that the distribution of ethical issues and reasons for moral distress are different than with adults. Pediatric EC often facilitates complex decision making among multiple stakeholders, and further prospective research is needed on the role of ethics consultation in pediatrics.     

Obesity Bias in Children: The Role of Actual and Perceived Body Size

The aim of this study was to examine how children perceive their body size and whether their actual or perceived body size can explain their anti‐fat views. Four hundred and fourteen 5–6, 7–8 and 9–10‐year‐old children were read short vignettes depicting two characters, one possessing a positive and the other a negative quality. Following each vignette, participants were asked to pick the story characters among thin, average and obese figures. Obesity bias was defined as the attribution of the positive quality to the thin or average figure and the corresponding negative one to the obese. Body mass index determined children's actual body size. Perceived body size was determined with the use of Collins' (1991) figures of increasing size. The results showed that actual body size affected the accuracy of perceived body size. While the majority of average children were accurate at identifying their body size, most overweight and obese children tended to underestimate it. The accuracy of body size perception improved with age. Obesity bias did not relate to children's actual but to their perceived body size: Those who perceived themselves as heavier exhibited less bias. The implications of the findings are discussed in relation to children's developing identity, and suggestions are made for future research. Copyright © 2014 John Wiley & Sons, Ltd.     

Personality traits as moderators of the associations between deployment experiences and PTSD symptoms in OEF/OIF service members

Abstract

This investigation examined traits from the five-factor model of personality as moderators of the associations of combat and aftermath of battle experiences with symptoms of posttraumatic stress disorder (PTSD) in 214 National Guard/Reserve service members deployed to operations enduring and Iraqi freedom. Extraversion significantly moderated the associations of both combat experiences and aftermath of battle experiences with PTSD severity, with associations weakening as levels of extraversion increased. The relation between aftermath of battle experiences and PTSD was also moderated by the other four personality factors, with the relation being weaker at higher levels of agreeableness, conscientiousness, and openness, and lower levels of neuroticism. These results suggest that personality traits may impact individual responses to war trauma, particularly war-related experiences that are not directly threatening to one's safety (i.e., aftermath of battle events vs. actual combat events). Although this investigation was cross-sectional, these findings indicate that personality traits are an important risk/resiliency factor to consider in people's responses to traumatic events.     

Using the Theory of Gender and Power to Examine Experiences of Partner Violence,Sexual Negotiation,and Risk of HIV/AIDS Among Economically Disadvantaged Women in Southern India

This article uses the Theory of Gender and Power to examine women's vulnerability to HIV/AIDS in order to: understand the vulnerability of female sex workers/poor women due to poverty and lack of educational resources; explore women's vulnerability in the context of client/partner violence, alcohol use, male partner's high-risk behaviors, and women's lack of control in their intimate relationships; and explore the role of traditional heterosexual gender norms in the outcomes of sexual negotiation. Ethnographic data were collected from 32 women and 38 men in India as part of an ongoing National Institute of Mental Health study. Results highlighted women's vulnerability to HIV/AIDS stemming from partner violence, alcohol use, poverty, dangers of sex work environments, and tacit acceptance of cultural/gender norms.     

Safety Planning Based on Lethality Assessment for Partners of Batterers in Intervention Programs

Summary

This chapter outlines a process of individualized safety planning with the partners of batterers in intervention programs that is based on the principles of empowerment and autonomy, and takes into account the context of the woman's situation. Assessing context is operationalized as considering the potential lethality of the situation from her partner, her relationship and emotional status, available resources, and her children. The safety planning process is described as an opportunity for the abused woman to gain information in order to strategize her responses. It is also a way for the program staff to gain more accurate information about the batterer's level of violence and dan-gerousness, and to work with women to enhance retention of abusers in the program.
