- OBJECTIVE: To test the hypothesis that cerebrospinal fluid (CSF)/ serum albumin ratios are increased in violent offenders. SUBJECTS AND METHODS: In a previous study of violent offenders, we found significantly higher CSF/serum album ratios (as a sign of increased blood-brain barrier permeability) in violent offenders than in healthy controls. For the present replication study, we recruited a new group of 28 violent offenders, aged 45 years or younger, and 20 new control subjects. RESULTS: The albumin ratio was again significantly higher in the offender group (mean 6.2) than in the control group (mean 4.6) (P = 0.012). Substance abuse or current medication did not appear to explain this finding. CONCLUSION: Increased CSF/serum albumin ratios are an unspecific sign of neurological dysfunction in subgroups of violent offenders.

- Since cross-sectional brain-imaging studies demonstrating frontotemporal cerebral hypoactivity in violent offenders have generally been carried out around the time of trial and sentencing, the findings might be influenced by the stressful situation of the subjects. It seems that no group of offenders with this finding has yet been followed longitudinally. We have re-examined nine offenders convicted of lethal or near-lethal violence in whom single photon emission tomography (SPECT) previously had demonstrated frontotemporal hypoperfusion. The mean interval between the initial and the follow-up examination was 4 years. The initially observed hypoactivity was found to have remained virtually unchanged at follow-up: no mean change in the group exceeded 5% in 12 assessed regions of interest. Although preliminary due to the small sample size, this study suggests that frontotemporal brain hypoactivity is a trait rather than a state in perpetrators of severe violent crimes.

- Attempting to avoid some of the most common methodological problems involved in research on sexual child abuse, we collected data on crimes, perpetrators, and sanctions in all convicted cases of sexual child abuse in a defined population during a 5-year period. This approach provided amply documented and ascertained cases with precise definitions and descriptions of the crimes involved, no clinical referral bias, and minimal dependence on memory effects. The results are valid for the small proportion of cases that lead to conviction in the context of Swedish legislation. Structured data were collected from the court dossiers in all cases of sexual crimes against minors (less than 15 years of age) tried and sentenced at the courts in the Västra Götaland region of Sweden between 1993 and 1997. The total number of 496 sentences for sexual crimes during the study period included 203 cases of sexual child abuse (40.8%) with 283 victims and 196 perpetrators, all men. Girls were victims in 85% of the cases, boys in 12%, and boys as well as girls in 3%. Sexual penetration had occurred in 54.5% of cases and the total proportion of hands-on crimes was 83%. Most perpetrators, 72%, were well known to the child. The most severe offenses took place within the family. A wide range of acts were classified as sexual child abuse, but most common was sexual penetration of a female child by her biological father or a family friend.

Age at onset of substance abuse: a crucial covariate of psychopathic traits and aggression in adult offenders.
- 2007

Tidskriftsartikel (refereegranskat)abstract
- To examine age at onset of substance abuse in relation to other factors of relevance to criminal behavior, we compared Life History of Aggression (LHA) scores, traits of psychopathy according to the Psychopathy Checklist--Revised (PCL-R), and violent recidivism in 100 violent offenders with early (before the age of 18) versus late onset of abuse or dependence. Of 56 subjects with a history of alcohol and/or drug abuse, an early onset was ascertained in 31. The duration of abuse did not correlate with the LHA and PCL-R scores or with violent recidivism, but the age at onset correlated strongly with all these factors and also remained their strongest correlate in multivariate models including childhood-onset attention deficit/hyperactivity disorder, conduct disorder, and drug abuse as covariates. Strong mathematical associations with aggression, psychopathy, and recidivism pointed to age at onset of substance abuse as a marker of possible complications that require preventive social, educational and medical measures.

Tidskriftsartikel (refereegranskat)abstract
- Aims: This prospective study was designed to replicate previous findings of an association between the platelet monoamine oxidase B (MAO-B) activity and factors of relevance for criminal behaviour in a well-documented clinical study population. Methods: Subjects (n = 77, aged 17-76 years, median 30 years) were recruited among consecutive perpetrators of severe interpersonal violent and/or sexual crimes referred to forensic psychiatric investigation. Participants were extensively investigated by structured psychiatric, psychological and social workups, including state-of-the-art rating instruments and official records, and with laboratory tests including venous blood sampling for determination of MAO-B activity. A subset of 36 individuals had lumbar punctures to measure cerebrospinal fluid concentrations of monoamine neurotransmitter metabolites. Results: Platelet MAO-B activity did not show any significant correlation with assessments of childhood behavioural disorders, substance abuse, or psychosocial adversity, nor with any crime-related factors, such as scores on the Life History of Aggression Scale, the Psychopathy Checklist or recidivistic violent crime. No significant correlation was found between MAO-B and any of the monoamine metabolites. Analyses in subgroups of smokers/non-smokers did not change this overall result. Conclusions: The findings of the present study did not support the use of MAO-B as a biological marker for aggression-related personality traits or as a predictor for violent recidivism among violent offenders.

Tidskriftsartikel (refereegranskat)abstract
- The prevention of aggressive behaviours is a core priority for psychiatric clinical work, but the association between the diagnostic concepts used in psychiatry and aggression remains largely unknown. Outpatients referred for psychiatric evaluations of childhood-onset neuropsychiatric disorders (n = 178) and perpetrators of violent crimes referred to pre-trial forensic psychiatric investigations (n = 92) had comprehensive, instrument-based, psychiatric assessments, including the Life History of Aggression (LHA) scales. Total and subscale LHA scores were compared to the categorical and dimensional diagnoses of childhood and adult DSM-IV axis I and II mental disorders, general intelligence (IQ), Global Assessment of Functioning (GAF), and personality traits according to the Temperament and Character Inventory (TCI). Overall, the two groups had similar LHA scores, but the offender group scored higher on the Antisocial subscale. Higher total LHA scores were independently associated with the hyperactivity facet of attention-deficit/hyperactivity disorder (AD/HD), childhood conduct disorder, substance-related disorders, and low scores on the Cooperativeness character dimension according to the TCI. IQ and GAF-scores were negatively correlated with the LHA subscale Self-directed aggression. Autistic traits were inversely correlated with aggression among outpatients, while the opposite pattern was noted in the forensic group. The findings call for assessments of aggression-related behaviours in all psychiatric settings.

Early Criminal Recidivism Among Mentally Disordered Offenders.
- 2012
-
Ingår i: International journal of offender therapy and comparative criminology. - 1552-6933.
-
Tidskriftsartikel (refereegranskat)abstract
- Criminal recidivism was studied during 2 years in a Swedish population-based cohort (N = 318) of mentally disordered male offenders who had undergone a pretrial forensic psychiatric investigation, been convicted in subsequent trials, and been sentenced to forensic psychiatric treatment (FPT; n = 152), prison (n = 116), or noncustodial sanctions (n = 50). Recidivism was analysed in relation to index sanctions, levels of supervision, diagnoses, and criminological factors. Significantly lower recidivism in the FPT group was related to lower crime rates during periods at conditional liberty in this group alone, and recidivism was significantly more common among offenders with at least one of the two diagnoses of substance abuse disorder and personality disorder than among those with psychotic or other mental disorders alone. Age at index crime and number of previous crimes emerged as significant predictors of recidivism. The results of this study suggest that the relapse rates depend as much on level of supervision as on individual characteristics.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To describe criminal recidivism, especially violent recidivism, in a long-term follow-up of mentally disordered offenders sentenced to different types of sanctions. Subjects and methods: A population-based Swedish cohort of male offenders referred to pre-trial psychiatric investigations between 1988 and 1995, was sentenced to forensic psychiatric treatment (n = 163), prison (n = 120), or noncustodial sanctions (n = 52). They were followed from the beginning of their sanctions until the end of June, 2008, through official health and crime registers. Survival analyses were used to compare time until violent recidivism across different sanctions and mental disorders, and predictors of violent recidivism were investigated using univariate comparisons, a multivariate Cox regression analysis and Receiver Operating Characteristic (ROC) curves. Finally, all criminal reconvictions until the end of follow-up were assessed (a total time period of 13 to 20 years). Results: Forty-seven percent of all subjects were reconvicted for violent crimes during follow-up. There were no significant differences between sanction groups. By contrast, diagnostic groups that included substance abuse had significant effects, and stood out as the strongest predictor of violent reconvictions together with the number of previous violent crimes, and age at the first registered criminal offence. Variables identified in the multivariate model together predicted violent recidivism with an area under the ROC curve of 0.72, while the corresponding figure for the age at onset of criminality as the sole predictor was 0.71. Among the different sanction forms for different time periods, time in hospital and prison were significantly less associated with violent recidivism compared to time in conditional release/probation.

Tidskriftsartikel (refereegranskat)abstract
- Rates of recidivism and types of recidivist crime have varied greatly in follow-up studies of child sexual abusers. In this long-term study of a population-based cohort (n = 193) and a nationwide clinic-referred study group (n = 166) of child sexual abusers, rates of recidivism and associations between index descriptors and outcomes were compared between intra-familial offenders and extra-familial offenders. Overall, 9.8% relapsed into sexual offence, 12.4% relapsed into violence and 2.6% relapsed into both types of offences in the population-based cohort. Corresponding numbers for the clinic-referred group were 13.9, 10.8 and 4.2%. Extra-familial offenders at index were significantly more likely to relapse into both sexual and violent criminality than intra-familial offenders, but no differences were found in rates of hands-off and hands-on crimes. Analysis of receiver operating characteristics showed that age at first conviction predicted sexual, violent and any criminality, with areas under the curve ranging from .67 to .80.
