A new procedure to compute weighted kappa with multiple raters is described. A resampling procedure to compute approximate probability values for weighted kappa with multiple raters is presented. Applications of weighted kappa are illustrated with an example analysis of classifications by three independent raters. 相似文献

IS SELF-OBJECTIFICATION RELATED TO INTEROCEPTIVE AWARENESS? AN EXAMINATION OF POTENTIAL MEDIATING PATHWAYS TO DISORDERED EATING ATTITUDES 总被引:1,自引:1,他引:0
Although there has been considerable empirical support for Objectification Theory ( Fredrickson & Roberts, 1997 ), findings have been mixed regarding self-objectification's relationship to interoceptive awareness, an awareness of one's internal physical and emotional states. We examined whether interoceptive awareness mediated the relationship between self-objectification and disordered eating attitudes, exploring more specifically the relative contributions of difficulties recognizing feelings of hunger and satiety versus emotions. College women ( N = 195) completed measures assessing self-objectification, interoceptive awareness, awareness of emotions, and disordered eating attitudes. Self-objectification correlated significantly more strongly with interoceptive awareness when internal cues about hunger and satiety were assessed. The relationship between self-objectification and disordered eating attitudes was partially mediated by interoceptive awareness. Results revealed that interoceptive awareness may best be captured by a measure that includes lack of awareness of both hunger and satiety and emotional states. Research and clinical implications of these findings are discussed. 相似文献

The current study involved a comprehensive comparative examination of overt and relational aggression and victimization across multiple perspectives in the school setting (peers, teachers, observers in the lunchroom, self-report). Patterns of results involving sociometic status, ethnicity and gender were explored among 4th graders, with particular emphasis on girls. Controversial and rejected children were perceived as higher on both forms of aggression than other status groups, but only rejected children were reported as victims. Both European American and African American girls showed a greater tendency toward relational aggression and victimization than overt aggression or victimization. Results indicated negative outcomes associated with both relational and overt victimization and especially overt aggression for the target girl sample. Poorer adjustment and a socially unskillful behavioral profile were found to be associated with these three behaviors. However, relational aggression did not evidence a similar negative relation to adjustment nor was it related to many of the behaviors examined in the current study. Implications of these results are discussed. 相似文献

Comments on the six articles contained in the special issue of the American Psychologist (January 2007) devoted to leadership, written by W. Bennis; S. J. Zaccaro; V. H. Vroom and A. G. Yago; B. J. Avolio; R. J. Sternberg; and R. J. Hackman and R. Wageman. The current authors express concern that the special issue failed to include attention to issues of diversity and intersecting identities as they pertain to leadership. A Special Issue Part II on Diversity and Leadership is being proposed to (a) advance new models of leadership, (b) expand on existing leadership theories, and (c) incorporate diversity and multiple identities in the formulation of more inclusive leadership research and theory. The goal of this special issue will be to revise our theories of leadership and our understanding of effective leadership to include gender, racial/ethnic minority status, sexual orientation, and disability status. 相似文献

The exact variance of weighted kappa with multiple raters 总被引:1,自引:0,他引:1
Weighted kappa described by Cohen in 1968 is widely used in psychological research to measure agreement between two independent raters. Everitt then provided the exact variance for weighted kappa for two raters. In this paper, Everitt's exact variance is extended to three or more raters. 相似文献

Non-suicidal self-injury (NSSI) is a complex behaviour, routinely engaged for emotion regulatory purposes. As such, a number of theoretical accounts regarding the aetiology and maintenance of NSSI are grounded in models of emotion regulation; the role that cognition plays in the behaviour is less well known. In this paper, we summarise four models of emotion regulation that have repeatedly been related to NSSI and identify the core components across them. We then draw on social cognitive theory to unite models of cognition and models of emotion in developing a new cognitive-emotional model of NSSI. Our model articulates how emotion regulation and cognition can work in concert to govern NSSI, and offers several new research questions that can be addressed within this framework. 相似文献

Traditional asymptotic probability values resulting from log-linear analyses of sparse frequency tables are often much too large. Asymptotic probability values for chi-squared and likelihood-ratio statistics are compared to nonasymptotic and exact probability values for selected log-linear models. The asymptotic probability values are all too often substantially larger than the exact probability values for the analysis of sparse frequency tables. An exact nondirectional permutation method is presented to analyze combined independent multinomial distributions. Exact nondirectional permutation methods to analyze hypergeometric distributions associated with r-way frequency tables are confined to r = 2. 相似文献

Traditional investigations of consumer choice processes include a matrix of alternatives described by attributes. The researcher-createdmatrix presents a product option space for the participant. In this article, we propose an alternative methodological approach to consumer choice processes. Specifically, we investigate choice processes when a participant creates his/her own product space. We describe a Web-based program and methodology used to collect data for three customizable products. Empirical results indicate that consumers are willing and able to make choices from their own product space. This research provides a new avenue for exploring choice processes. 相似文献

Adaptive social behavior frequently involves discriminating between classes of individuals such as relatives versus non-relatives, older versus younger individuals, or individuals of different status. In the absence of spatial cues, this discrimination may be based on signals that correlate with fitness-related traits (e.g., older or high-status males may sing higher performance songs) or with identity, for example, when receivers distinguish and classify signalers based on their unique signal structure. Here, we examine vocal age-based discrimination in western bluebirds (Sialia mexicana), a North American songbird in which older males have a significant advantage in obtaining extra-pair fertilizations, and therefore pose a significantly higher threat to paternity than younger males. We asked whether western bluebird males showed a higher response to playback of songs of older males compared to younger males relative to their own age. We prepared song stimuli by removing three potential signals of age that have been identified as important in other species: (1) note consistency (which was achieved by playing a single instance of each note repeatedly), (2) note repertoire size, and (3) singing rate (the latter two were equalized across conditions). Even in the absence of these potential signals of age, young males responded more strongly to playback of older males’ songs than to young males’ songs, suggesting that they are able to discriminate between age classes relative to the threat they pose. Further research is required to determine whether this discrimination is based on individual recognition or signal features that are correlated with age. 相似文献
