“…According to some research results, proactive aggression is associated with delinquent and antisocial behaviors (Fite et al, 2008b;Raine et al, 2006;Scarpa et al, 2010;Vitaro et al, 2006), and psychopathic tendencies (Cornel et al, 1996;Porter et al, 2003;Woodworth and Porter, 2002). Some research indicates that reactive aggression is not directly associated with delinquency (Raine et al, 2006;Vitaro et al, 2006).…”

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 in four high schools in Hatay, Turkey. One-factor and twofactor models were compared in the study of Confirmatory Factor Analysis conducted to examine the construct validity of the scale and the two-factor model was found to have better fit values for both junior high school and high school students, as well as the general study group as a whole. It was found that reactive and proactive aggressions have significant relations with attitude towards violence, trait anger, delinquency, deviant peers, anxiety, depression and hostility. Furthermore, it was determined that the scale has high internal consistency and item-total correlation. The results obtained in this study are consistent with the results of the original form of the scale. Findings of the study demonstrate that the Turkish version of RPQ has adequate reliability and validity values.

Psychopathy: Assessment and Forensic Implications

2009

Psychopathy was the first personality disorder to be recognized in psychiatry. The concept has a long historical and clinical tradition, and in the last decade a growing body of research has supported its validity. 1, p 28 I n the decade following this 1998 statement, the theoretical and empirical literature on psychopathy has expanded virtually at an exponential rate, with the addition of well over 500 scientific publications and many books and edited volumes. Much of this literature examines and evaluates the application of psychopathy to the mental health and criminal justice systems, 2-4 where it has been described as "the most important and useful psychological construct yet discovered for criminal justice policies" 5, p 231 and as "what may be the most important forensic concept of the early 21st century." 6, book jacket However, the past few years have also seen a dramatic increase in basic research based on the theories and methodologies from basic science including, but certainly not limited to, behavioural genetics, developmental psychopathology, cognitive-affective neuroscience, biochemistry, general personality theory, 7 and organizational psychology. 8 In 2004, the SSSP was established as a vehicle for the exchange of ideas and research findings among international investigators. Because psychopathy is associated with so much social and personal damage and distress, the basic and applied research endeavours are now

“…18 A study that does provide a more detailed definition defines gratuitous violence as 'excessive violence that went beyond the level that would be necessary to accomplish the homicide and/or caused the victim unnecessary pain and suffering.' 19 Another study indicates that the term is used 'if the amount of violence clearly exceeded the degree of force that that would have been necessary to merely control the victim.' 20 In the latter definitions violence is not gratuitous if it seems to be necessary to carry out a certain crime (the principal offence), but comes to be seen as gratuitous once it goes beyond that which is necessary for this purpose.…”

“…They also suggest that 'thrill seeking' may be a factor in some psychopathic violence. 42 However, as indicated, it is not only these instrumental or expressive motives that characterise psychopathic violence, but also that it is 'unemotional' and 'cold-blooded'. Psychopaths 'consistently commit more violence' and 'perpetrated the most severe … acts of physical abuse.'…”

Anger, hatred, or just heartlessness? Defining gratuitous violence

Violent crime in South Africa is sometimes said to be unusual, because it is perceived to frequently be gratuitous. This article engages with the question of how to define gratuitous violence. If the term gratuitous is understood to mean 'for nothing', gratuitous violence should be understood as violence that is 'low on expressive and instrumental motivations'. Whilst the evidence is that much violence is 'instrumental', violence in South Africa may be unusual but it may be better to articulate this in terms of the concepts both of 'expressive' and gratuitous violence. Gratuitous violence and the apparent cruelty that characterises some acts of instrumental violence also appear to imply that 'empathy deficits' might be a characteristic of many perpetrators of violence.
