Introduction

Physicians vary in their moral judgments about health care costs. Social intuitionism posits that moral judgments arise from gut instincts, called “moral foundations.” The objective of this study was to determine if “harm” and “fairness” intuitions can explain physicians’ judgments about cost-containment in U.S. health care and using cost-effectiveness data in practice, as well as the relative importance of those intuitions compared to “purity”, “authority” and “ingroup” in cost-related judgments.

Methods

We mailed an 8-page survey to a random sample of 2000 practicing U.S. physicians. The survey included the MFQ30 and items assessing agreement/disagreement with cost-containment and degree of objection to using cost-effectiveness data to guide care. We used t-tests for pairwise subscale mean comparisons and logistic regression to assess associations with agreement with cost-containment and objection to using cost-effectiveness analysis to guide care.

Results

1032 of 1895 physicians (54%) responded. Most (67%) supported cost-containment, while 54% expressed a strong or moderate objection to the use of cost-effectiveness data in clinical decisions. Physicians who strongly objected to the use of cost-effectiveness data had similar scores in all five of the foundations (all p-values?>?0.05). Agreement with cost-containment was associated with higher mean “harm” (3.6) and “fairness” (3.5) intuitions compared to “in-group” (2.8), “authority” (3.0), and “purity” (2.4) (p?<?0.05). In multivariate models adjusted for age, sex, region, and specialty, both “harm” and “fairness” were significantly associated with judgments about cost-containment (OR?=?1.2 [1.0-1.5]; OR?=?1.7 [1.4-2.1], respectively) but were not associated with degree of objection to cost-effectiveness (OR?=?1.2 [1.0-1.4]; OR?=?0.9 [0.7-1.0]).

Conclusions

Moral intuitions shed light on variation in physician judgments about cost issues in health care.

This article addresses the relation between defensive dissociation and faith. Defensive dissociation is understood as a response to severe trauma. In this response there is no interpreting subject to process the event linguistically and the result is fragments of unformulated memory that continue to be painfully present long after the original trauma. The victim of severe trauma alternates between the need to be here in the presence of other human beings and the dissociative isolation of not being here. There are two related claims in this article. First, defensive dissociation stands for an event where faith is annihilated. As a defense it protects a person's remnant sense of faith, subjectivity, agency, and personhood by creating a space of non-experience. Fragments of annihilated faith continue to be present in the person's present formulations of faith and concomitant behaviors, relationships, and use of objects. The second claim is that the core of severe trauma remains outside the victim and community's capacities to represent it symbolically. This incommunicable core of annihilated faith can be contained by a community of faithful persons who are willing to face the horror of non-being and being nowhere without succumbing to despair.  相似文献

This paper explores the connection between quality of life and direct democracy. Using state level data for participation and quality of life, we find that those states with a high quality of life see higher participation in direct democracy than those with lower quality of life. However, the passage of direct democracy measures has the inverse relationship indicating the importance of maintaining the status quo for states with higher quality of life measurements.  相似文献

Changes in sensation (e.g., prickly skin) are crucial constituents of emotional experience, and the intensity of perceived changes has been linked to emotional intensity and dysregulation. The current study examined the relationship between sensory sensitivity and emotion regulation among adults with anorexia nervosa (AN), a disorder characterised by disturbance in the experience of the body. Twenty-one individuals with AN, 20 individuals with AN who were weight–restored, and 23 typical controls completed self-report measures of sensory sensitivity and emotion regulation. AN participants reported heightened sensory sensitivity and greater difficulty regulating emotions relative to controls. Self-perceived sensory sensitivity was associated with greater emotion dysregulation. Weight-restored AN participants reported greater ability to regulate emotions than their currently underweight counterparts, despite heightened sensitivity. Findings suggest that hypersensitivity may be a persisting feature in AN, and that weight restoration may involve improved ability to cope with sensation.  相似文献

This study is another contribution to the development of a satisfactory child version of the linguistic task of judging grammaticality. With a nondifferentially reinforced forced-choice procedure, it was found that responses of 24 5- and 24 7-yr-old children did vary as a function of the grammatical complexity of stimulus sentences. The children judged sentence stimuli of two types (negatives and wh-word questions) each having three levels of grammatical complexity (two primitive and one well-formed). After each stimulus presentation, the subject pointed to the adult or the child in a photograph, depending on who was judged to have produced that utterance. Performance of the two age groups did not differ for the question stimuli, for which subjects pointed to the adult more frequently as the grammatical complexity of wh-word questions increased. In response to the negative sentences, the older group attributed more well-formed stimuli to the adult than primitive ones. While the younger group pointed to the adult more frequently for well-formed negatives than for the middle level negatives, they made more adult responses than expected to the least complex negatives. It was concluded that, with this procedure, 5- and 7-yr-olds demonstrate ability to distinguish grammatically well-formed from primitive sentences. Procedural improvements for future research may allow children this age and younger to demonstrate more adult-like discrimination between a variety of primitive and well-formed sentences.  相似文献
