The purpose of this study was to examine affective, behavioral, and cognitive functioning in adolescents with multiple suicide attempts. Forty-seven adolescents with a history of multiple suicide attempts (MA) were compared to 74 single suicide attempters (SA) on psychiatric diagnosis, depressive symptoms, affect regulation, self-mutilation, alcohol use, and hopelessness. Results revealed that the MA group was more likely to be diagnosed with a mood disorder, and reported more severe depressive symptoms and anger, in comparison to the SA group. Behaviorally, the MA group had higher rates of disruptive behavior disorders and higher levels of affect dysregulation and serious self-mutilation than the SA group. Further, greater levels of hopelessness were reported by the MA than the SA group. After controlling for a mood disorder diagnosis, only differences in anger, affect dysregulation, and serious self-mutilation remained significant. Overall, results suggest that treatment with adolescent suicide attempters might specifically target anger and affect dysregulation to reduce risk for future suicidal behavior.  相似文献

Biomedicine is a global enterprise constructed upon the belief in the universality of scientific truths. However, despite huge scientific advances over recent decades it has not been able to formulate a specific and universal definition of death: In fact, in its attempt to redefine death, the concept of death appears to have become immersed in ever increasing vagueness and ambiguity. Even more worrisome is that bioethics, in the form of principlism, is also endeavouring to become a global enterprise by claiming neutrality. It appears that the discourse within both disciplines have similarly manipulated the boundaries of death to include the “dying”. This paper argues that the redefinition of death debate in biomedicine reveals a concept of personhood which is profoundly western in origin and which is in accordance to the concept adhered to within principlism. Biomedicine and bioethics do not appear to acknowledge the limitations of their own world view and hence lack an understanding of their applicability and appropriateness in diverse social and cultural contexts; a situation which adds credence to claims as to the hegemonic and imperialistic nature of all such global enterprises.

One hundred sixty-three young adolescents (72 males, 91 females) were administered a 23-item self-report inventory measuring antisocial behaviors. Results were analyzed separately for males and females. Exploratory factor analysis showed antisocial behavior to be multidimensional and to have different factor structures for males and females. The three factors accounting for more than two-thirds of the variance in antisocial behavior are discussed in terms of specialization in drug/alcohol use and violence.  相似文献

New opportunities for discourse about God have arisen, along with new challenges to the mainstream Catholic theology of God. In order to take advantage of these opportunities, a truly contemporary Catholic theology of God must critically appropriate three 'events' which have affected its approach to the subject matter: (1) Heidegger's periodizing critique of ontotheology; (2) the 'contemporary' viewed as the arena of contention between modern and postmodern claims; (3) the presence of the Kingdom of God and the revelation of the nature of God in the person and work of Jesus Christ, which alter our understandings of time and being. The present essay sketches a program for an authentically Catholic response to the issues raised by these occurrences, emphasizing the Catholic commitment to incarnation and sacramentality and the necessary effort to retrieve redemptive images of God from modernity, despite the present tendency of some postmodern theologians and philosophers to dismiss aspects of the past as unusable.  相似文献

This study assessed the performance of the PC-PTSD in diagnosing postdeployment posttraumatic stress disorder (PTSD) in a cohort of Air Force Medical Services personnel (N = 18,530). The prevalence of PTSD in the cohort was 5.18% based on medical record data. The area under the receiver operating characteristic curve was 0.69, indicating poor classification accuracy. Sensitivity was 47.55%, specificity was 90.68%, positive predictive value was 21.79%, and negative predictive value was 96.94%. The positive and negative likelihood ratios were 5.10 and 0.58, respectively. Several risk factors were found to be associated with a diagnosis of postdeployment PTSD: being a nurse, being enlisted in the medical service career field, being enlisted in the mental health service career field, those over age 30, being a member of the Active Duty service component, and having one’s first deployment be to Iraq. Being an officer was found to be a protective characteristic. These factors could potentially improve screening for PTSD among Air Force healthcare personnel.  相似文献

A large body of research has focused on how people exchange and use information during the negotiation process. This work tends to treat information as if it all were readily available upon request. The current research investigated how delays in the pursuit of missing information can influence people’s ex-ante priorities and the final settlements they reach. Study 1 found that negotiators achieved more value on an issue after seeking missing information about that issue compared to when the same information was readily accessible. Study 2 found that the effect of searching for information on outcomes was mediated by changes in how important negotiators perceived the issue to be. Theoretical and practical implications are discussed.  相似文献

It is known that properties of words such as their imageability can influence our ability to remember those words. However, it is not known if other object-related properties can also influence our memory. In this study we asked whether a word representing a concrete object that can be functionally interacted with (i.e., high-manipulability word) would enhance the memory representations for that item compared to a word representing a less manipulable object (i.e., low-manipulability word). Here participants incidentally encoded high-manipulability (e.g., CAMERA) and low-manipulability words (e.g., TABLE) while making word judgments. Using a between-subjects design, we varied the depth-of-processing involved in the word judgment task: participants judged the words based on personal experience (deep/elaborative processing), word length (shallow), or functionality (intermediate). Participants were able to remember high-manipulability words better than low-manipulability words in both the personal experience and word length groups; thus presenting the first evidence that manipulability can influence memory. However, we observed better memory for low- than high-manipulability words in the functionality group. We explain this surprising interaction between manipulability and memory as being mediated by automatic vs. controlled motor-related cognition.  相似文献
