Statistical modelling in the investigation of stranger rape

JOURNAL OF INVESTIGATIVE PSYCHOLOGY AND OFFENDER PROFILING, Issue 1 2010

Abstract A sample of stranger rape offences (n = 271) registered in the Dutch Violence Crime Linkage Analysis System database in the Netherlands between 1997 and 2007 was studied with the objective of developing statistical models, which give an indication of the probability of basic offender characteristics. Observable crime characteristics concerning the modus operandi, interaction between the offender and the victim, violence, precautionary measures, and sexual behaviours were selected in the dataset. Offender characteristics were selected based on their usefulness for the police organisation in narrowing the scope of a criminal investigation. Spatial behaviour, criminal history, and living situation of the offender were selected. From the predictive models, four out of five achieved a correct rate of over 70%, and all models predicted better than the best guess method. The proposed models for distance and prior convictions for violence seem particularly promising. Both these models show an improvement of correctly predicted offender characteristics of more than 20 percentile points compared with that which could have been estimated based on the average in the total sample. The predictive value of the models needs to be tested further with ,new offences', which were not used to construct the model. In general, the current study supports the finding that crime characteristics can be used to get an indication of the probability of certain offender characteristics. Nevertheless, for an understanding of the relationship between the crime characteristics and offender characteristics, a further development of a theoretical framework is urgently necessary.

Schema-driven information processing in judgements about rape

APPLIED COGNITIVE PSYCHOLOGY, Issue 5 2007
Barbara Krahé
Two studies addressed the impact of rape schemata on judgements about rape cases. In Study 1, 286 undergraduate students rated perpetrator and victim blame for five rape scenarios and completed the Perceived Causes of Rape Scale. Most blame was assigned to victims of an ex-partner rape, followed by acquaintance and stranger rape. Least blame was assigned to perpetrators of ex-partner rapes, followed by acquaintance and stranger rapes. Female precipitation beliefs increased victim blame and reduced perpetrator blame. In Study 2, 158 students rated rape scenarios that varied in victim perpetrator relationship and coercive strategy and completed a measure of Female Precipitation Beliefs. Half expected to be held accountable for their judgements. The perpetrator was held less liable and the victim blamed more when the perpetrator exploited the victim's incapacitated state versus using physical force. Accountability instruction reduced the impact of female precipitation beliefs on perceived perpetrator liability and victim blame. Copyright © 2006 John Wiley & Sons, Ltd. [source]

Crime scene actions and offender characteristics in a sample of Finnish stranger rapes

Abstract The crime scene actions employed by offenders in stranger rapes were analysed in relation to offender characteristics. Data were drawn from an official police database and consisted of stranger rapes occurring in Finland between 1992 and 2001 (n,=,100). The structure of dichotomous variables derived through a content analysis of crime scene actions and offender characteristics were analysed with non-metric multidimensional scaling (MDS). The first analysis revealed three separate action themes, with thematic emphases on Hostility, Involvement or Theft. The MDS-solution for offender characteristics suggested four themes: Conventional; Psychiatric/Elderly; Criminal/Violent; and Criminal/Property. Each case was assigned to one of the themes or as a hybrid in order to analyse the associations between action themes and characteristics. The only significant association was found between the action theme, Theft and characteristics theme Criminal/Property. The results are discussed in relation to previous research.

Schema-driven information processing in judgements about rape

When is profiling possible?

BEHAVIORAL SCIENCES & THE LAW, Issue 6 2007
Offense planning, aggression as moderators in predicting offender age from victim age in stranger rape
Debate continues with regard to the possibility of inferring an offender's characteristic features from crime scene details (the process of so-called "offender profiling"). We argue that psychology generally has benefited from appreciating context in predicting behavior. In the same way, profiling would benefit from an appreciation of context in predicting characteristics. This "reverse" process is contingent on various "if,then" relationships. As one example, this paper demonstrates how profiling offender age from victim age is contingent on (i) the level of planning and (ii) the level of aggression displayed during the offense. Eighty-five stranger rape case records formed the data set. Moderated regression analysis revealed that victim age is a significant predictor of offender age only in cases where the offender has (i) shown evidence of planning the attack and/or (ii) acts in a gratuitously aggressive manner. The theoretical bases for these findings may lie in the extent to which offenders disparately plan and target victims and how extreme aggressiveness in stranger rapes may relate to a near-peer proxy for an offender's anger. The implications of the results for the processes and methods involved in offender profiling suggest that certain crime scene factors can have differential moderating effects on predictive outcomes.
