The Role of Rape Myth Acceptance and Psychopathy in Sexual Assault Perpetration

Perpetrators of sexual aggression consistently report higher scores on measures of psychopathy and acceptance of rape myths relative to nonperpetrators. However, less is known about psychopathy among nonincarcerated individuals and the relation between the two constructs has not been empirically examined among college perpetrators. To address this gap, both constructs were measured in a sample (N?=?308) of college men. Rape myth acceptance was positively correlated with psychopathy, and perpetrators scored higher on both constructs. Myths transferring responsibility to victims were related to Factor 1 psychopathy (i.e., callous and manipulative traits). The myth that “rape is trivial” was associated with Factor 1 and Factor 2 (i.e., impulsive and antisocial behavior), possibly suggesting that this myth is related to a larger tendency to excuse aggressive behavior. Although both constructs distinguished perpetrators when considered individually, rape myth acceptance did not explain unique variance in the presence of psychopathy.     

Ordinal consistency and ordinal true scores

This paper argues that test data are ordinal, that latent trait scores are only determined ordinally, and that test data are used largely for ordinal purposes. Therefore it is desirable to develop a test theory based only on ordinal assumptions. A set of ordinal assumptions is presented, including an ordinal version of local independence. From these assumptions it is first shown that the gamma-correlation between two tests is the product of their gamma-correlations with the true latent order. The theory is generalized to allow for heterogeneous tests by defining a weighted average local independence. The tau-correlations between total score and the latent order can be found in both homogeneous and heterogeneous cases, and a system of differential item weighting to maximize the tau-correlation between weighted items and the latent order is provided. Thus a purely ordinal test theory seems possible.Part of this work was done while the author was a Visiting Fellow at Macquarrie University. The paper has benefitted from discussions with Professors Thomas J. Reynolds and Roderick P. McDonald and from the comments of several anonymous reviewers.     

质性研究中编码者信度的多种方法考察

质性研究中检验编码者信度的方法有归类一致性指数、编码信度系数、相关系数、中位数检验、概化系数等。基于教师胜任力访谈数据集,对编码者信度考察结果表明,归类一致性指数和编码信度系数受相同编码数影响而不稳定,相关系数受数据类型制约,中位数检验受研究设计影响,概化系数则受编码者和编码项目的数量影响。研究中须合理选用。     

Elaboration et validation de tests de jugement situationnel comme outil de sélection professionnelle : guide méthodologique

Current views in personnel selection recognize the necessity for situational judgements tests (SJT) which are closed to the real work context of companies. The SJTs have also become a popular selection tool across Europe. SJTs are attractive because they show good validity, positive applicants reactions and can be cost effective to test large group of applicants at once. The aim of this paper is to describe a structured methodology for the elaboration of such test. Each stage is illustrated by examples and psychometrics validation issues are discussed.     

The Effect of Social and Situational Factors on the Intended Response to Aggression Among Adolescents

ABSTRACT

In this study, I explored intended response to aggression among adolescents. I drew hypotheses from social identity theory, cost/benefit considerations, and social information processing model. I asked 217 Jewish and Muslim male adolescents in this study to assess their intended use of aggression in 12 hypothetical conflict situations (vignettes), in which I manipulated the opponent's religion, gender, acquaintance, and severity of aggression. I mainly found that male adolescents respond to aggression by same-religion opponents more moderately than to cross-religion aggression; their response is more moderate to cross-gender aggression than to same-gender aggression; response is more moderate to the aggression of familiar opponents than to that of unfamiliar ones; and response is less severe toward moderate than toward severe aggression.     

Preliminary Examination of a Cartoon-Based Hostile Attributional Bias Measure for Urban African American Boys

The current study illustrates how researchers developed and validated a cartoon-based adaptation of a written hostile attributional bias measure for a sample of urban, low-income, African American boys. A series of studies were conducted to develop cartoon illustrations to accompany a standard written hostile attributional bias vignette measure (Study 1), to determine initial psychometric properties (Study 2) and acceptability (Study 3), and to conduct a test–retest reliability trial of the adapted measure in a separate sample (Study 4). These studies utilize a participatory action research approach to measurement design and adaptation, and suggest that collaborations between researchers and key school stakeholders can lead to measures that are psychometrically strong, developmentally appropriate, and culturally sensitive. In addition, the cartoon-based hostile attributional bias measure appears to have promise as an assessment and/or outcome measure for aggression and bullying prevention programs conducted with urban African American boys.     

Development of the Social Behavior of Two Mice Species With Contrasting Social Systems

The house mouse (Mus musculus) and the mound‐building mouse (M. spicilegus) differ in their mating and social systems. The M. musculus is polygynous and females tend to breed cooperatively while M. spicilegus is known to be monogamous and famous for its unique cooperative behavior; the communal overwintering. Mus spicilegus is considered as a highly aggressive species in the genus Mus. In the present study, we attempted to analyze the development of aggressive and sociable behavior in these species and to discover how familiarity with the target moderates the development of sociable and aggressive behaviors and moderates the differences between the species. Dyadic social interaction tests in neutral cages were performed on 21‐, 60‐, and 120‐day‐old mice of both genders and both species. Each individual was tested against a sibling and an unfamiliar individual at all three ages. Our results showed that the development of aggressive and sociable behavior with age differed between the species and sexes; however, familiarity with the other mouse moderated the effect of species on aggression. At 21 days, both genders of M. spicilegus were more aggressive against strangers than siblings. This became true of both species at 60 days. When facing a stranger, both sexes of M. spicilegus were more aggressive than M. musculus at 120 days. However, when facing a sibling, neither gender of M. spicilegus was more agonistic than M. musculus, indicating that either kinship or early social experiences elicit tolerance. Aggr.

Locus of control as a contributing factor in the relation between self-perception and adolescent aggression

Researchers continue to debate the role of self-esteem in aggression, but research has shown a consistent association between narcissism and aggression in adults and adolescents [e.g., Barry et al., 2007; Bushman and Baumeister, 1998; Stucke, 2007]. The primary aim of the current study was to examine whether locus of control (LOC) moderated the relation between self-perception variables (i.e., self-esteem and narcissism) and aggression in adolescents. Participants were 174 youth (145 males, 26 females) between the ages of 16 and 19 who were enrolled in a voluntary residential program for youth who have dropped out of school. The results showed that LOC moderated the association between self-esteem and aggression such that low self-esteem was associated with higher levels of aggression for individuals with an external LOC. Contrary to expectations, LOC failed to moderate the narcissism-aggression relation. The implications of this study for understanding how self-perception is related to adolescent aggression are discussed.     

An Examination of Network Position and Childhood Relational Aggression: Integrating Resource Control and Social Exchange Theories

Applying resource control theory and social exchange theory, we examined the social network conditions under which elementary age children were likely to engage in relational aggression. Data on classroom peer networks and peer‐nominated behaviors were collected on 671 second‐ through fourth‐grade children in 34 urban, low‐income classrooms. Nested regression models with robust cluster standard errors demonstrated that the association between children's number of relationships and their levels of relational aggression was moderated by the number of relationships that their affiliates had. Children with more peer relationships (i.e., higher network centrality) exhibited higher levels of relational aggression, but only when these relationships were with peers who had fewer connections themselves (i.e., poorly connected peers). This finding remained significant even when controlling for common predictors of relational aggression including gender, overt aggression, prosocial behavior, victimization, social preference, and perceived popularity. Results are discussed in terms of their implications for advancing the literature on childhood relational aggression and their practical applications for identifying children at risk for these behaviors.
