The authors tested effects of a 10-week group cognitive-behavioral stress management intervention among 100 women newly treated for Stage 0-II breast cancer. The intervention reduced prevalence of moderate depression (which remained relatively stable in the control condition) but did not affect other measures of emotional distress. The intervention also increased participants' reports that having breast cancer had made positive contributions to their lives, and it increased generalized optimism. Both remained significantly elevated at a 3-month follow-up of the intervention. Further analysis revealed that the intervention had its greatest impact on these 2 variables among women who were lowest in optimism at baseline. Discussion centers on the importance of examining positive responses to traumatic events--growth, appreciation of life, shift in priorities, and positive affect-as well as negative responses.  相似文献

This study examined individuals' tendencies to migrate from one organization to another (i.e., the propensity to switch employers). Previous researchers have suggested that switching organizations throughout the career span may be partially heritable and therefore related to individual differences in personality traits. If personality traits are indeed related to a tendency to turnover from organizations, this suggests that current procedures for calculating utility may be inaccurate. Using a database of 1081 individuals who have been in the workforce for several years, results indicated that personality traits measured by the Occupational Personality Questionnaire (non‐ipsative; OPQn) were modestly related to organization switching (i.e., repeated moves from organization to organization). We found that higher scores on extraversion, openness to experience, and conscientiousness‐related traits were modestly correlated with more frequent organization switching. However, we demonstrate that these modest relationships can produce large inaccuracies in utility estimates.  相似文献

Abstract: One claim about I , regularly made and almost universally endorsed, is that uses of the term are logically guaranteed to refer successfully (if they refer at all). The claim is only rarely formulated perspicuously or argued for. Such obscurity helps disguise the fact that those who profess to advance the claim actually turn out to support not a logical guarantee at all but merely high security through fortunate coincidence. This is not surprising. For we have no good reason to accept the claim – granted, any use of I is apt to refer successfully; but that can be explained by pragmatic features of its use. And we have some reason to reject the claim – it is notoriously difficult to see how genuine reference and guaranteed success do not exclude each other when considered as properties of the logic of any term.  相似文献
