Predictors for repetition of suicide attempts were evaluated among 92 adolescent suicide attempters 9 years after an index suicide attempt (90% females). Five were dead, two by suicide. Thirty-one (42%) of 73 had repeated a suicide attempt. In multiple Cox regression analysis, four factors had an independent predictive effect: comorbid disorders, hopelessness, having ever received treatment for mental or behavior problems, and having a father exerting control without affection. Prediction on an individual level was difficult. Since almost half repeated a suicidal act, the best strategy is to evaluate all adolescent suicide attempters thoroughly and provide treatment as needed.  相似文献

EXPLAINING EMERGENCE: TOWARDS AN ONTOLOGY OF LEVELS   总被引:1,自引:0,他引:1  
The vitalism/reductionism debate in the life sciences shows that the idea of emergence as something principally unexplainable will often be falsified by the development of science. Nevertheless, the concept of emergence keeps reappearing in various sciences, and cannot easily be dispensed with in an evolutionary world-view. We argue that what is needed is an ontological non reductionist theory of levels of reality which includes a concept of emergence, and which can support an evolutionary account of the origin of levels. Classical explication of emergence as “the creation of new properties” is discussed critically, and specific distinctions between various kinds of emergence is introduced for the purpose of developing an ontology of levels, framed in a materialistic and evolutionary perspective. A concept of the relation between levels as being inclusive is suggested, permitting the “local” existence of different ontologies. We identify, as a working hypothesis, four primary levels and explicate their nonhomomorphic interlevel relations. Explainability of emergence in relation to determinism and predictability is considered. Recent research in self-organizing non-linear dynamical systems represents a revival of the scientific study of emergence, and we argue that these recent developments can be seen as a step toward a final “devitalisation” of emergence.  相似文献

Mental speed is a common concept in theories of cognitive aging, but it is difficult to get measures of the speed of a particular psychological process that are not confounded by the speed of other processes. We used Bundesen’s (1990) Theory of Visual Attention (TVA) to obtain specific estimates of processing speed in the visual system controlled for the influence of response latency and individual variations of the perception threshold. A total of 33 non‐demented old people (69–87 years) were tested for the ability to recognize briefly presented letters. Performance was analyzed by the TVA model. Visual processing speed decreased approximately linearly with age and was on average halved from 70 to 85 years. Less dramatic aging effects were found for the perception threshold and the visual apprehension span. In the visual domain, cognitive aging seems to be most clearly related to reductions in processing speed.  相似文献

This study sought to disentangle the effects of different kinds of stress on maternal ratings of child externalizing and internalizing problems, social inhibition, and social competence, with a primary focus on parenting stress. The relations were explored in a sample consisting of mothers of 436 children (Mage = 7 years) in Sweden. Half the sample had had early clinical contacts during infancy due to child regulation problems, and the rest were mothers without known such early contacts. Demographic factors, family stressors, and parenting stress were examined in stress – adjustment models. Family stressors were clinical contact during infancy, current child and parent health problems, recent negative life events, and insufficient social support. Parenting stress as a mediator of the effect of other stressors on rated child adjustment was tested as was social support as a moderator of the effect of parenting stress on adjustment. The results showed that a higher parenting stress level was associated with maternal ratings of more externalizing and internalizing behaviors, more social inhibition, and lower social competence. Other family stressors and background variables were also found to be of importance, mainly for externalizing and internalizing problems and to some extent for social competence. Social inhibition had a unique relation to parenting stress only. Parenting stress mediated effects of other stressors in twelve models, whereas social support had no moderating effect on the link between parenting stress and child adjustment. Thus, parenting stress seems to be an important overarching construct. Clinical implications are proposed.  相似文献

Past work has established a connection between self-esteem and self-presentation; however, research has not explored how self-esteem that is contingent on one's relationship may influence self-presentational tactics in that relationship. Across two studies, undergraduate students reported on the extent to which their self-esteem depended on their friendship and romantic relationship, as well as the extent to which they engaged in self-presentation behaviors in those relationships. The results suggest that relationship-specific contingent self-esteem predicts relationship-specific self-presentation; however, friendship-contingent self-esteem predicted self-presentation in both friendships and romantic relationships. These results suggest that individuals are keenly and differentially attuned to qualitatively different relationships, and when perceiving potential problems, they attempt to remedy those through their self-presentations. Furthermore, results indicate the possibility that self-esteem tied to a particular relationship may not be as important as self-esteem based more generally on one's relationships.  相似文献

Wiium, N. & Aarø, L.E. (2011). Outcome expectations and use of smokeless tobacco (snus): A cross‐sectional study among young Norwegian snus users. Scandinavian Journal of Psychology 52, 64–70. In this study, measures of outcome expectancies related to use of snus (wet snuff) were used to predict reported frequency of snus use. Data stem from a nation‐wide survey in Norway among 16‐ to 20‐year‐olds. Only users of snus were included in the statistical analyses (n = 589). The main outcome measure, frequency of snus use, was measured as a categorical variable – occasional, weekly and daily use. Four dimensions of outcome expectancies (mood regulation, smoking control, weight control and negative health outcomes) were measured and confirmed in a confirmatory factor analysis. Informants tended to believe that snus use is harmful to health, but still they supported the idea of snus as a way to control own cigarette smoking. In a SEM model, two of the four dimensions of outcome expectancies turned out to be particularly significant predictors of frequency of snus use – mood regulation and smoking control. No significant interactions with gender were found. Males scored higher than females on “mood regulation”, and “smoking control”, while females scored higher than males on “negative health outcomes”. If more smokers were convinced that snus use is a less harmful alternative, more of them might start using snus, not only because there is some association between health outcome expectancies and snus use, but also because snus use by many is perceived as a remedy to stop smoking and as a way to gain some of the mood regulation benefits which are usually associated with smoking.  相似文献
