There has been an increase in peer violence in Vietnam. Although normative beliefs approving aggression have been considered an important factor in the development of peer violence in Western countries, few studies examine the factor in Vietnamese context. This limitation may be due to the lack of a validated scale used to evaluate the factor. The…

This study assessed the psychometric properties of the Dutch translation of the Prosocial Behavior Questionnaire (PBQ-NL), a self-report questionnaire that distinguishes altruistic, reactive, and proactive prosocial behaviours. Participants were 381 Dutch adolescents and young adults aged 13-30 (M[subscript age] = 18.62, SD = 2.59, 65.1% female).…

School bullying is a significant public health problem and a widespread type of school violence. Empirically validated evaluation scales are needed for use in research and practice to explain the nature and scope of adolescent bullying. The current study investigated the multilevel factor structure and measurement invariance of the Olweus…

Background: We analyze trends in bullying victimization prevalence in a representative sample of Spanish adolescent schoolchildren in 2006, 2010, and 2014. Methods: We distinguish between reported bullying, which is assessed via the global question in the Revised Bully/Victim Questionnaire by Olweus, and observed bullying, which is a measure…

The aim of this study was to adapt the Reactive-Proactive Aggression Questionnaire (RPQ), developed to measure two dimensions of aggression which are reactive and proactive, to Turkish and test the validity and reliability of the Turkish form. The study group consisted of 278 students in four junior high schools in Adana, Turkey, and 485 students…

Treatments for disruptive behaviors are often guided by parent reports on questionnaires, rather than by multiple methods of assessment. Professional observations and clinic analogs exist to complement questionnaires, but parents can also collect useful behavioral observations to inform and guide treatment. Two parent observation methods of child…

The well-known distinction between reactive and proactive aggression is theoretically important but empirically controversial. Recently, aggression researchers have argued that we should separate the form and function of aggression to make a clearer distinction between reactive and proactive aggression. This article describes the validation of a…

The distinctiveness of physical aggression from other antisocial behavior is widely accepted but little research has explicitly focused on young children to empirically test this assumption. A Multitrait-Multimethod Matrix (MTMM) approach was employed to confirm the distinctiveness of physical aggression from nonaggressive antisocial behavior in…

Existing research posits multiple dimensions of bullying and victimization but has not identified well-differentiated facets of these constructs that meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differentiated factors that are not so highly correlated as to detract…

The efficacy of the Good Behavior Game was examined in a multiethnic New York City public high school. Classroom rules were posted and students were divided into two teams. A reinforcement preference questionnaire was used to select daily and weekly prizes. The classroom teacher indicated that he was going to place a check on the board after every…

Aggressive behavior between children in schools is a topic that receives much interest as violence and aggressive behavior cause many maladaptive social outcomes in the school setting. In the current study the Implicit Association Test (IAT) was adapted as a measure of children's implicit aggression, by assessing the association of the self…

The current paper provides external validation of the bifactor model of ADHD by examining associations between ADHD latent factor/profile scores and external validation indices. 548 children (321 boys; 302 with ADHD), 6 to 18 years old, recruited from the community participated in a comprehensive diagnostic procedure. Mothers completed the Child…

Researchers using scenarios often neglect to validate perceived content and salience of embedded stimuli specifically with intended participants, even when such meaning is integral to the study. For example, sex and aggression stimuli are heavily influenced by culture, so participants may not perceive what researchers intended in sexual aggression…

The present study examined the validity of the Basic Empathy Scale (BES) [Jolliffe, D., & Farrington, D. P. (2006a). Development and validation of the Basic Empathy Scale. "Journal of Adolescence," 29, 589-611; Jolliffe, D., & Farrington, D. P. (2006b). Examining the relationship between low empathy and bullying. "Aggressive…

The construct validity of the Bully/Victim Questionnaire (Olweus, 1996a) as a measure of bullying was examined. Although researchers have defined bullying and reactive aggression as two distinct types of aggression, this study examined how closely related they are using empirical data. Reports from students and teachers on measures of bullying and…
