ABSTRACT
BACKGROUND: Substance use regularly co-occurs with many types of criminality, including violent behaviour. AIM: To review the relationships between substance abuse and criminality, which can involve violent behaviour. METHOD: We searched the literature for meta-analyses, reviews and empirical articles about relationships between the problematic use of and addiction to psychoactive substances on the one hand and antisocial and aggressive behaviour and recidivism on the other hand. RESULTS: In the case of both men and women there are significant relationships between substance abuse and criminal behavior. The majority of substance users, however, are not criminals and most of the offences they commit can be termed 'acquisitive offences'. The relationship between alcohol and violence is stronger than the relationship between substance abuse and violence. Furthermore, it is only in cocaine users that we find indications that psychopharmacological effects stimulate violent behaviour. A number of factors, particularly interactions, determine whether substance abusers are criminal and are violent. Violent behaviour can result from interactions between the severity of illness caused by substance abuse, individual psychological, social and neurobiological characteristics, situational factors and expectancies regarding the psychopharmacological effects of a particular substance. CONCLUSION: Substance abuse, particularly the combination of alcohol and drugs, is a predictor of criminality and criminal recidivism.

BACKGROUND: In forensic psychiatry it is essential that patients' risks of reoffending are assessed as reliably as possible. The risk assessment instrument hkt-30 assesses both static and dynamic risk factors. It is assumed that dynamic risk factors should change when a patient receives treatment. AIM: To find out whether dynamic risk factors changed during the course of forensic psychiatric treatment. METHOD: The hkt-30 was administered 984 times for forensic psychiatric patients in 3 different forensic psychiatric centres, in the period June 2003-November 2006. For 513 patients the instrument was administered at least once, for 313 this was done at least twice and for 158 patients for three years in succession. By subdividing the research group into 'new', 'old' and 'transferred' patients we were able to examine in which phase of treatment the largest changes in hkt-30 scores occurred. RESULTS: More than half the scores for dynamic risk factors, as well as the total score, declined significantly as treatment progressed, but the differences were small in absolute terms. The three subgroups of patients hardly differed from each other with regard to the degree of change. CONCLUSION: The scores for the risk factors, assumed in theory to be changeable, seemed to become lower as the treatment progressed. However, it is not yet certain whether these lower scores were in fact directly linked to a reduction on the risk of reoffending.

The unidimensionality of nicotine dependence has not been established firmly yet. The aim of this study was to assess the dimensionality of nicotine dependence, preferably meeting the strict assumptions of the Rasch model. First, we examined the validity of the Fagerström Test for Nicotine Dependence (FTND) [Br. J. Addict. 86 (1991) 1119.] in 1525 smokers who participated in a national survey considering smoking behavior. Two factors were found, suggesting that the FTND does not measure a unidimensional construct. Factor analysis of 19 other dependence items in 512 smokers resulted in four factors of which three were interpretable: compulsive smoking, social problems due to smoking, and physical dependence. We focused on smoking compulsivity. This factor turned out to consist of a four-item Rasch homogeneous scale. Two items of the FTND with face validity of smoking compulsivity were found to fit into the scale. The results of Rasch analysis were in support of a continuum of compulsivity. Difficulty refraining from smoking in places where it is forbidden was found to indicate highest compulsivity. Several correlates with smoking compulsivity were found. We conclude that compulsive smoking is one important dimension of nicotine dependence, which may account for the considerable relapse of this disorder.
