A total of 480 patients were treated in a large, multicenter randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behavior therapy (MACT) versus treatment as usual (TAU) for recurrent deliberate self-harm. Each patient was randomized after a self-harm episode assessed at an accident and emergency center and followed up over 1 year. The main hypothesis tested was that those allocated to MACT would have a lower proportion of self-harm episodes in the succeeding year. A total of 60% of those allocated to MACT had face-to-face treatment and 430 (90%) of all patients had self-harm data recorded after 1 year. Although the results showed no significant difference between those repeating self-harm in the MACT group (39%) compared with the TAU group (46%) (P = 0.20), the treatment was cost effective (10% cheaper than TAU) and the frequency of self-harm episodes was fewer (50%) in the MACT group. A total of nine of 10 patients had some personality disturbance (42% of these with disorder), and for those where information on parasuicide events was collected, the proportion having a repeat episode ranged from 33% to 63% for different personality disorders. Those with BPD were most likely to repeat episodes quickly (mean 89 days for 25% to repeat) with dissocial personality disorder (equivalent mean 384 days) the slowest to repeat. Total costs were significantly greater in those with personality disorder and were reduced in those allocated to MACT; this saving was reversed in those with borderline disorder. On average, MACT appeared to increase the cost of those patients with BPD (BPD) and reduce the cost of those with other personality disorders. It is concluded that MACT has value in preventing self-harm cost effectively but this appears to be confined mainly to those who do not have BPD. 相似文献

Similarity as transformation 总被引:2,自引:0,他引:2
We propose that similarity is determined by the transformation distance between representations: entities which are perceived to be similar have representations which are readily transformed into one another, whereas transforming between dissimilar entities requires many transformations. We present three experiments that indicate that similarity is strongly influenced by transformation distance. These data present a challenge for featural or spatial accounts of similarity. Finally, we introduce a family of transformation-based accounts of similarity, called 'Representational Distortion', as a specific example of a transformational approach to similarity. 相似文献

Recently (Troje, Huber, Loidolt, Aust, & Fieder 1999), we found that pigeons discriminated between large sets of photorealistic frontal images of human faces on the basis of sex. This ability was predominantly based on information contained in the visual texture of those images rather than in their configural properties. The pigeons could learn the distinction even when differences of shape and average intensity were completely removed. Here, we proved more specifically the pigeons' flexibility and efficiency to utilize the class-distinguishing information contained in complex natural classes. First, we used principal component as well as discriminant function analysis in order to determine which aspects of the male and female images could support successful categorization. We then conducted various tests involving systematic transformations and reduction of the feature content to examine whether or not the pigeons' categorization behaviour comes under the control of categorylevel feature dimensions-that is, those stimulus aspects that most accurately divide the stimulus classes into the experimenter-defined categories of 'Male' and 'Female'. Enhanced classification ability in the presence of impoverished test faces that varied only along one of the first three principal components provided evidence that the pigeons used these class-distinguishing stimulus aspects as a basis for generalization to new instances. 相似文献

In 1993 Albach investigated the long-term consequences of sexual abuse on psychological health. A group of abused women a a control group of nonabused women were asked to fill in a questionnaire assessing posttraumatic stress disorder (PTSD). For ethical reasons, the abused women were warned that filling in the questionnaire might be emotionally stressful. The control group did not receive this warning. The abused women scored higher on the questionnaire than the nonabused women. The warning they received may have influenced their reports. Our experiment investigated this. 101 psychology students were divided into two groups, one who received a warning and a control group who did not. The hypothesis was that people who had been previously warned would score higher on a PTSD questionaire than people who had not. There were, however, no significant differences in mean PTSD scores and no known initial differences between groups. 相似文献

Social identity theory suggests that individuals and groups use different identity management strategies to cope with threatened identities. In October 1998, the authors developed 5 identity management strategy scales for use in the changing political context of Northern Ireland and investigated the relationship of perceptions of stability and legitimacy, as well as in-group identification, to those strategies. Participants were 209 students of the University of Ulster and the Belfast Institute. The results supported the factor structure of the identity management strategy scales. Perceptions of stability and legitimacy and in-group identification were, however, correlated with some strategies only. That finding may indicate that some identity management strategies are related to psychological constructs not covered by social identity theory. 相似文献

An application of item response theory to the DSM-III-R criteria for borderline personality disorder
This paper summarizes results from analyses of the DSM criteria for borderline personality disorder (BPD) using models from item response theory (IRT). The study sample consisted of 353 participants, the majority of whom were psychiatric patients. Confirmatory factor analysis showed that a one-factor model provided the best fit to the data. All the DSM BPD criteria had moderate or higher item discrimination parameters, indicating that all items contributed meaningful information in assessing BPD. Item information functions revealed that the BPD criteria as a whole were useful for capturing BPD traits in the moderately severe to severe range, but that they performed less well in the less severe range. The general conclusion is that the criteria do represent a coherent syndrome and that further research on the informational value of the individual criteria would be useful. 相似文献

Slippery slope arguments (SSAs) have often been viewed as inherently weak arguments, to be classified together with traditional
fallacies of reasoning and argumentation such as circular arguments and arguments from ignorance. Over the last two decades
several philosophers have taken a kinder view, often providing historical examples of the kind of gradual change on which
slippery slope arguments rely. Against this background, Enoch (2001, Oxford Journal of Legal Studies
21(4), 629–647) presented a novel argument against SSA use that itself invokes a slippery slope. Specifically, he argued that
the very reasons that can make SSAs strong arguments mean that we should be poor at abiding by the distinction between good
and bad SSAs, making SSAs inherently undesirable. We argue that Enoch’s meta-level SSA fails on both conceptual and empirical
grounds. 相似文献

The ChiP-C is a clinically oriented questionnaire for assessing the quality of the child-parent relationship according to the child’s subjective appraisal. The ChiP-C is based on family systems theory and a cumulative vulnerability model. The questionnaire consists of 36 items representing three resource scales, five risk scales, and one additional scale. This article presents the theoretical framework and main psychometric properties of the ChiP-C. A school-based sample of 1,377 youth (ages 10–20; M = 14.4) and a clinic-referred consecutive sample of 197 patients (ages 10–18, M = 14.0) were surveyed. Construct validity was determined by confirmatory factor analyses. The mean of the internal consistencies was 0.79. Systematic correlations between the ChiP-C scales and the German EMBU confirmed the convergent and discriminant validity of the ChiP-C. Moreover, all ChiP-C scales were shown to be significantly correlated with psychopathological symptoms as measured by parent and youth questionnaires. The ChiP-C can be considered an economical screening instrument for a reliable and valid assessment of strengths and disturbances of the child-parent relationship according to the child’s subjective appraisal. 相似文献
