Psychopathy in violent female offenders in Finland

BACKGROUND: The base rate and construct of psychopathy in violent female offenders were examined. SAMPLING AND METHODS: More than half of all violent female offenders in Finland who where either hospitalised (n=12) or incarcerated (n=46) during the year of the study were assessed by the Hare Psychopathy Checklist-Revised (PCL-R), Structured Clinical Interview II for DSM-IV, Beck Anxiety Inventory, Beck Depression Inventory-II and Wechsler Adult Intelligence Scale-Revised. RESULTS: PCL-R mean scores and a base rate of psychopathy were found to be in line with earlier studies, showing both lower values and prevalence in females. The PCL-R correlated with symptoms of cluster B personality disorders as well as with depressive personality disorder. Factor 2 was observed to positively correlate with anxiety and depression and negatively with verbal cognitive ability. Logistic regression analysis on the PCL-R items revealed that the items shallow affect, lack of remorse or guilt, conning/manipulation and lack of realistic goals seem to be important indicators of female psychopathy together with callous/lack of empathy, impulsivity and failure to accept responsibility for own actions. CONCLUSION: The finding indicates that the prevalence of psychopathy is lower among female offenders than among male offenders, but further research is needed to examine the base rate of psychopathy in women, and whether the symptoms of psychopathy are expressed differently in women than in men.     

Intoxication and violent women

Alcohol and drugs have been linked to severe violent offending among women as well as men. The purpose of this study was to make a contribution to the limited knowledge of characteristics related to the state of intoxication in violent female offenders. The putative differences in the characteristics of female offenders and their violent offenses in relation to the state of intoxication at the time of the violent offending were examined. Of a nation-wide sample of 109 female offenders found guilty of homicide and other violent crimes and incarcerated in 1999–2000 in Finland, 60 offenders participated in the study. Of these offenders 49 (81.7%) had been intoxicated at the time the of index offenses. These were compared with 11 (18.3%) non-intoxicated offenders using a structured interview, the Structured Clinical Interview II for DSM-IV (SCID-II) and the Hare Psychopathy Checklist-Revised (PCL-R). The prevalence of substance abuse or dependence (73.3% and 0%), personality disorder (89.6% and 36.4%), particularly antisocial personality disorder (66.7% and 0%), as well as a history of criminality (69.4% and 0%) were significantly higher among the intoxicated women than among the non-intoxicated. The PCL-R scores were also significantly higher among the intoxicated offenders than among non-intoxicated offenders. The victims of the intoxicated women (23.9%) were less often emotionally close to the perpetrator than were the victims of the non-intoxicated women (66.6%). No differences emerged between the groups in experiences of childhood and adulthood abuse or stressful life events prior to the index crime. The findings indicate that intoxicated violent female offenders exhibit more of the characteristics previously found in violent men, than do the non-intoxicated female offenders. Moreover, the non-intoxicated group comprises both psychotic non-responsible and non-psychotic, fairly well-adjusted women, who are educated, working or studying at the time of the offense and has no history of criminality. Substance misuse constitutes an obvious risk factor for violent behavior in women, and therefore the prevention should include substance abuse treatment.     

Changes over time in homicides by women: a register‐based study comparing female offenders from 1982 to 1992 and 1993 to 2005

Background The contribution of women to violent offending, including homicide, may be increasing as society changes. Aims The aim of this paper was to test for trends in homicide by women in Finland. Methods A retrospective register‐based study was conducted by comparing two national cohorts: one from 1982 to 1992 and the other from 1993 to 2005. Results There was a small increase in the proportion of homicides committed by women over time, but the most striking difference between the cohorts was in the significantly higher frequency of alcohol abuse/dependence in the later cohort and of being under the influence of alcohol during the crime. Fewer perpetrators were regarded as lacking or being of diminished responsibility in the later cohort. The victims of the earlier cohort were emotionally closer to the offender than those of the later one. Conclusions In Finland, there have been changes in characteristics of women who commit homicide and their crimes over time, with the apparent development of a subgroup of women who kill who are much more like men who kill than women in the 1980s and early 1990s. Preventing substance abuse and marginalization are likely to be important ways of preventing homicide by both female and male perpetrators. Copyright © 2008 John Wiley & Sons, Ltd.     

Gender differences in homicide offenders' criminal career,substance abuse and mental health care. A nationwide register‐based study of Finnish homicide offenders 1995–2004

Background It is generally considered that women who kill are more likely to have a psychiatric disorder than their male counterparts, but as a relatively small group, women are much less often studied than men in this context. Aim To explore gender differences in the psychosocial history of homicide offenders. Method In this nationwide register‐based study, data were extracted from the forensic psychiatric examination and crime reports of all 91 women prosecuted for homicide in Finland between 1995 and 2004 and from those of the next adjacent man convicted of a separate homicide (n = 91). Results Both female and male homicide offenders had a troubled childhood, but more women had witnessed or experienced family violence; more women had failed to complete their primary education. Men, however, were more likely to have had an offending history. Although there were no differences between the men and women in the frequencies of psychiatric diagnoses or of substance abuse, the women had more often received prior mental health treatment. The women were also more likely to have had a history of suicidal behaviour. Conclusions Both female and male homicide offenders are a troubled group of people, with slightly different criminal careers. Many use mental health services and therefore prevention could be improved. The suggestion of a special sub‐group of women characterised by early educational and behavioural difficulties needs replication, as it may have implications for service development.

Filicide in Austria and Finland - A register-based study on all filicide cases in Austria and Finland 1995-2005

Background

It has been suggested that dopamine dysfunction may play a role in bipolar disorder (BD). An indirect approach to examine this issue was developed, focusing on associations between dopamine proxy measures observed in BD (dopamine-related clinical traits using tardive movement syndromes as dopamine proxy measure of reference).

Methods

3459 eligible bipolar patients were enrolled in an observational study. Incidence rates of tardive movement syndromes (tardive dyskinesia and tardive dystonia; TDD) were examined. A priori hypothesized associations between incident TDD and other dopamine proxies (e.g. prolactin-related adverse effects, bipolar symptoms) were tested over a 2 year follow-up period.

Results

The incidence rate of tardive syndromes was 4.1 %. Incident TDD was independently associated not only with use of antipsychotics, but also with more severe bipolar symptoms, other extrapyramidal symptoms and prolactin-related adverse effects of medication.

Conclusion

Apart from the well-known association with antipsychotics, development of TDD was associated with various other dopamine proxy measures, indirectly supporting the notion of generalised dopamine dysregulation in BD.     

Violence in a Finnish forensic psychiatric hospital

Background: Patients with schizophrenia have a high risk of cardiovascular disease (CVD). High aerobic intensity training (HIT) improve peak oxygen uptake (VO_2peak), net mechanical efficiency of walking and risk factors for CVD but has not been investigated in patients with schizophrenia. Aims: To investigate effects from HIT on VO_2peak, net mechanical efficiency of walking and risk factors for CVD in patients with schizophrenia. Methods: 25 inpatients (F20–29, ICD-10) were allocated to either HIT or playing computer games (CG), 3 days per week for 8 weeks. HIT consisted of 4 × 4-min intervals with 3-min break periods, at 85–95% and 70% of peak heart rate, respectively. Results: 12 and seven patients completed HIT and CG, respectively. The baseline VO_2peak in both groups combined (n = 19) was 36.8 ± 8.2 ml/kg/min and 3.12 ± 0.55 l/min. The HIT group improved VO_2peak by 12% from 3.17 ± 0.59 to 3.56 ± 0.68 l/min (P < 0.001), more than the CG group (P = 0.014). Net mechanical efficiency of walking improved by 12% in the HIT group from 19.8 ± 3.0% to 22.2 ± 4.5% (P = 0.005), more than the CG group (P = 0.031). The psychiatric symptoms, expressed as the Positive and Negative Syndrome Scale (PANSS) and the Calgary Depression Scale for Schizophrenia (CDSS), did not improve in either group. Conclusions: VO_2peak and net mechanical efficiency of walking improved significantly by 8 weeks of HIT. HIT should be included in rehabilitation in order to improve physical capacity and contribute risk reduction of CVD.     

Potential predictors in neonaticide: the impact of the circumstances of pregnancy

This study aims to evaluate the psychosocial factors of neonaticide, especially the circumstances before delivery, the relationships of the pregnant women, and their social environment awareness of women's pregnancy. This nationwide study was register-based, comprising all known neonaticides in Austria and Finland between 1995 and 2005. Cases (n = 28) were obtained by screening the death certificates from coroner's departments and by analyzing them along with all further available reports. Few women (17.9 %, 5/28) admitted their pregnancy to others. Although most (16/28) offenders were in a relationship, the partner had knowledge of the pregnancy in only three cases. The main motive for negation of the pregnancy (named in 60.8 % of cases) was fear of abandonment/negative response from others. The fertility rate among the women was high, but half of those with children had lost the custody of them. In neonaticide, the lack of awareness surrounding offenders' pregnancy, as well as the awareness of social environment, is more relevant than any other social variable.
