Differentiating Male and Female Intimate Partner Homicide Perpetrators : A Study of Social, Criminological and Clinical Factors
- 2016

Tidskriftsartikel (refereegranskat)abstract
- It is recognized that the majority of intimate partner homicide (IPH) victims are female; simultaneously, when females do commit homicide, they are more likely to perpetrate against an intimate partner. To date, there are only a few studies that discuss IPH across gender, leading to a gap of knowledge with regard to gender aspects of perpetration. The present nationwide study has a retrospective design, based on registries of all female (n = 9) and stratified male (n = 36) IPH committed in Sweden between 2007 and 2009. Our study suggests that female perpetrators are more likely to be unemployed, to have suffered from a substance abuse disorder at some point in life and to have been victimized by the victim. In other words, scrutiny of these characteristics reveals that females who commit partner-related homicides are qualitatively and clinically different from their male counterparts. Furthermore, the prevailing feature of intoxication in connection to the crime, both in male and female perpetrators, indicates that perpetrators might benefit from elements of substance abuse treatment in interventions targeting partner violence.

Tidskriftsartikel (refereegranskat)abstract
- Functional neuroimaging of social anxiety disorder (SAD) support altered neural activation to threat-provoking stimuli focally in the fear network, while structural differences are distributed over the temporal and frontal cortices as well as limbic structures. Previous neuroimaging studies have investigated the brain at the voxel level using mass-univariate methods which do not enable detection of more complex patterns of activity and structural alterations that may separate SAD from healthy individuals. Support vector machine (SVM) is a supervised machine learning method that capitalizes on brain activation and structural patterns to classify individuals. The aim of this study was to investigate if it is possible to discriminate SAD patients (n = 14) from healthy controls (n = 12) using SVM based on (1) functional magnetic resonance imaging during fearful face processing and (2) regional gray matter volume. Whole brain and region of interest (fear network) SVM analyses were performed for both modalities. For functional scans, significant classifications were obtained both at whole brain level and when restricting the analysis to the fear network while gray matter SVM analyses correctly classified participants only when using the whole brain search volume. These results support that SAD is characterized by aberrant neural activation to affective stimuli in the fear network, while disorder-related alterations in regional gray matter volume are more diffusely distributed over the whole brain. SVM may thus be useful for identifying imaging biomarkers of SAD.

Tidskriftsartikel (refereegranskat)abstract
- Social anxiety disorder (SAD) has been associated with aberrant processing of socio-emotional stimuli and failure to adaptively regulate emotion, corroborated by functional neuroimaging studies. However, only a few studies of structural brain abnormalities in SAD have been reported, and among these only one investigated cortical thickness. In the present study we used magnetic resonance imaging (MRI) in conjunction with an automated method to measure cortical thickness in patients with SAD (n=14) and healthy controls (n=12). Results showed significantly increased thickness of the left inferior temporal cortex in SAD patients relative to controls. Within the patient group, a negative association was found between social anxiety symptom severity and thickness of the right rostral anterior cingulate cortex. The observed alterations in brain structure may help explain previous findings of dysfunctional regulation and processing of emotion in SAD.

Tidskriftsartikel (refereegranskat)abstract
- Antisocial and violent behaviour have been associated with both structural and functional brain abnormalities in the frontal and the temporal lobes. The aim of the present study was to assess cortical thickness in offenders undergoing forensic psychiatric assessments, one group with psychopathy (PSY, n = 7) and one group with autism spectrum disorder (ASD, n = 7) compared to each other as well as to a reference group consisting of healthy non-criminal subjects (RG, n = 12). A second aim was to assess correlation between scores on a psychopathy checklist (PCL-SV) and cortical thickness. Magnetic resonance imaging (MRI) and surface-based cortical segmentation were used to calculate cortical thickness. Analyses used both regions of interest and statistical maps. When the two groups of offenders were compared, there were no differences in cortical thickness, but the PSY group had thinner cortex in the temporal lobes and in the whole right hemisphere compared to RG. There were no differences in cortical thickness between the ASD group and RG. Across subjects there was a negative correlation between PCL-SV scores and cortical thickness in the temporal lobes and the whole right hemisphere. The findings indicate that thinner cortex in the temporal lobes is present in psychopathic offenders and that these regions are important for the expression of psychopathy. However, whether thinner temporal cortex is a cause or a consequence of the antisocial behaviour is still unknown.

Effects of 25 mg oxazepam on emotional mimicry and empathy for pain : a randomized controlled experiment
- 2017
-
Ingår i: Royal Society Open Science. - : The Royal Society. - 2054-5703. ; 4:3
-
Tidskriftsartikel (refereegranskat)abstract
- Emotional mimicry and empathy are mechanisms underlying social interaction. Benzodiazepines have been proposed to inhibit empathy and promote antisocial behaviour. First, we aimed to investigate the effects of oxazepam on emotional mimicry and empathy for pain, and second, we aimed to investigate the association of personality traits to emotional mimicry and empathy. Participants (n= 76) were randomized to 25mg oxazepam or placebo. Emotional mimicry was examined using video clips with emotional expressions. Empathy was investigated by pain stimulating the participant and a confederate. We recorded self-rated experience, activity in major zygomatic and superciliary corrugator muscles, skin conductance, and heart rate. In the mimicry experiment, oxazepam inhibited corrugator activity. In the empathy experiment, oxazepam caused increased self-rated unpleasantness and skin conductance. However, oxazepam specifically inhibited neither emotional mimicry nor empathy for pain. Responses in both experiments were associated with self-rated empathic, psychopathic and alexithymic traits. The present results do not support a specific effect of 25mg oxazepam on emotional mimicry or empathy.

Oxazepam and cognitive reappraisal : A randomised experiment
- 2021
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 16:4
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Cognitive reappraisal is a strategy for emotional regulation, important in the context of anxiety disorders. It is not known whether anxiolytic effects of benzodiazepines affect cognitive reappraisal.Aims: We aimed to investigate the effect of 25 mg oxazepam on cognitive reappraisal.Methods: In a preliminary investigation, 33 healthy male volunteers were randomised to oxazepam or placebo, and then underwent an experiment where they were asked to use cognitive reappraisal to upregulate or downregulate their emotional response to images with negative or neutral emotional valence. We recorded unpleasantness ratings, skin conductance, superciliary corrugator muscle activity, and heart rate. Participants completed rating scales measuring empathy (Interpersonal Reactivity Index, IRI), anxiety (State-Trait Anxiety Inventory, STAI), alexithymia (Toronto Alexithymia Scale-20, TAS-20), and psychopathy (Psychopathy Personality Inventory-Revised, PPI-R).Results: Upregulation to negative-valence images in the cognitive reappraisal task caused increased unpleasantness ratings, corrugator activity, and heart rate compared to downregulation. Upregulation to both negative- and neutral-valence images caused increased skin conductance responses. Oxazepam caused lower unpleasantness ratings to negative-valence stimuli, but did not interact with reappraisal instruction on any outcome. Self-rated trait empathy was associated with stronger responses to negative-valence stimuli, whereas self-rated psychopathic traits were associated with weaker responses to negative-valence stimuli.Conclusions: While 25 mg oxazepam caused lower unpleasantness ratings in response to negative-valence images, we did not observe an effect of 25 mg oxazepam on cognitive reappraisal.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPrevious research suggests that female violent offenders at risk of a prison sentence are more likely than their male counterparts to be assessed as having mental health problems of a nature or degree that would lead to a court requirement for hospital treatment.Aims/hypothesesTo test the hypothesis that there is bias towards hospital disposal of female compared with male violent offenders with mental disorder.MethodsIn Sweden, the National Board of Forensic Medicine oversees all assessments of mental disorder for the criminal courts. Twenty-six Board appointed forensic psychiatrists, psychologists and social workers each independently assessed six case vignettes for fit with criteria for ‘severe mental disorder’, a prerequisite for hospital disposal from court. Each gender neutral vignette described a person who had been convicted of serious assault and had a major mental disorder. A gender was then assigned to each offender randomly within a block design, thus varying between sets. Participants were blind to the main aim of the study and the gender variation.ResultsThere was no significant association between gender of the person assessed and judgement that s/he had a ‘severe mental disorder’. An offender depicted as having mental retardation was more likely to be assessed as at high risk of criminal recidivism if portrayed as female, regardless of the sex, place of work or level of experience of the assessor.ConclusionWe found no evidence of gender bias in determining appropriateness of a hospital disposal of an offender with mental disorder. The difference in assessment of recidivism according to sex of the patient was only in relation to mental retardation; further research would be needed to able to interpret this. As researchers in other countries have reported gender bias in disposals from court, our findings may provide support for a centralised forensic psychiatric assessment board and formal, on-going training.

Tidskriftsartikel (refereegranskat)abstract
- Assessments of psychopathic traits are used on a routine basis in forensic evaluations across Westernized countries. Despite this, consensus has not yet emerged concerning what exactly are the “core” features of this construct. Moreover, relatively little is known about how practitioners in the field construe this disorder. This study explored perceptions and attitudes regarding psychopathy among individuals working in the forensic mental health system (N = 90) in Sweden. Participants provided prototype ratings of what they considered to be core psychopathy features based on the Comprehensive Assessment of Psychopathic Personality (CAPP), a model that increasingly is the focus of research in North America and Europe. The study protocol also included questions regarding (a) global perceptions and attitudes about a number of aspects of the psychopathy construct (e.g., personal experience, perceived prevalence), and (b) attitudinal scales that assessed perceived correlates of psychopathic traits across a variety of domains (e.g., violence proneness, treatment amenability) and moral judgments and attitudes concerning how psychopathic offenders should be treated within the legal system. The majority of the 33 individual CAPP items and the six CAPP scales were rated as at least moderately prototypical of psychopathy, with Dominance, Self, and Attachment domains obtaining the highest mean ratings. Participants viewed psychopaths as more likely to commit crimes than the average criminal, without being blatantly “evil” people. We believe our results help to advance our understanding of the psychopathy construct by exploring forensic professionals’ perceptions of this disorder in general and in relation to the CAPP model specifically.

Tidskriftsartikel (refereegranskat)abstract
- Perceptions of mental health conditions influence how individuals with psychiatric diagnoses are treated within the community, in the legal system, and at different institutions. We examined perceptions of mental health conditions among lay judges (N = 643), working at district and appellate courts throughout Sweden. Participants read a web-based survey including a crime vignette in which the person charged with a crime was described as having schizophrenia (n = 186), antisocial personality disorder (ASPD) with psychopathic traits (n = 219), or intellectual disability (n = 238). Participants' perceptions of schizophrenia were largely in line with Swedish legislation regarding the medicolegal concept of severe mental disturbance (SMD). Findings were more varied for the other two conditions, however. Perceptions of individuals with ASPD with psychopathic traits were not consistent with the Swedish SMD legislation. The results highlight the complexity of legislation addressing mental illness and criminality.

Reliability and Construct Validity of the Psychopathic Personality Inventory-Revised in a Swedish Non-Criminal Sample : A Multimethod Approach including Psychophysiological Correlates of Empathy for Pain
- 2016
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 11:6
-
Tidskriftsartikel (refereegranskat)abstract
- Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples. To address this gap in the literature, we examined PPI-R’s reliability, construct validity and factor structure in non-criminal individuals (N = 227) in Sweden, using a multimethod approach including psychophysiological correlates of empathy for pain. PPI-R construct validity was investigated in subgroups of participants by exploring its degree of overlap with (i) the Psychopathy Checklist: Screening Version (PCL:SV), (ii) self-rated empathy and behavioral and physiological responses in an experiment on empathy for pain, and (iii) additional self-report measures of alexithymia and trait anxiety. The PPI-R total score was significantly associated with PCL:SV total and factor scores. The PPI-R Coldheartedness scale demonstrated significant negative associations with all empathy subscales and with rated unpleasantness and skin conductance responses in the empathy experiment. The PPI-R higher order Self-Centered Impulsivity and Fearless Dominance dimensions were associated with trait anxiety in opposite directions (positively and negatively, respectively). Overall, the results demonstrated solid reliability (test-retest and internal consistency) and promising but somewhat mixed construct validity for the Swedish translation of the PPI-R.

MYO5B mutations in pheochromocytoma/paraganglioma promote cancer progression
- 2020

Ingår i: PLOS Genetics. - : Public Library of Science. - 1553-7390 .- 1553-7404. ; 16:6

Tidskriftsartikel (refereegranskat)abstract
- Identification of additional cancer-associated genes and secondary mutations driving the metastatic progression in pheochromocytoma and paraganglioma (PPGL) is important for subtyping, and may provide optimization of therapeutic regimens. We recently reported novel recurrent nonsynonymous mutations in the MYO5B gene in metastatic PPGL. Here, we explored the functional impact of these MYO5B mutations, and analyzed MYO5B expression in primary PPGL tumor cases in relation to mutation status. Immunohistochemistry and mRNA expression analysis in 30 PPGL tumors revealed an increased MYO5B expression in metastatic compared to non-metastatic cases. In addition, subcellular localization of MYO5B protein was altered from cytoplasmic to membranous in some metastatic tumors, and the strongest and most abnormal expression pattern was observed in a paraganglioma harboring a somatic MYO5B:p.G1611S mutation. In addition to five previously discovered MYO5B mutations, the present study of 30 PPGL (8 previous and 22 new samples) also revealed two, and hence recurrent, mutations in the gene paralog MYO5A. The three MYO5B missense mutations with the highest prediction scores (p.L587P, p.G1611S and p.R1641C) were selected and functionally validated using site directed mutagenesis and stable transfection into human neuroblastoma cells (SK-N-AS) and embryonic kidney cells (HEK293). In vitro analysis showed a significant increased proliferation rate in all three MYO5B mutated clones. The two somatically derived mutations, p.L587P and p.G1611S, were also found to increase the migration rate. Expression analysis of MYO5B mutants compared to wild type clones, demonstrated a significant enrichment of genes involved in migration, proliferation, cell adhesion, glucose metabolism, and cellular homeostasis. Our study validates the functional role of novel MYO5B mutations in proliferation and migration, and suggest the MYO5-pathway to be involved in the malignant progression in some PPGL tumors. © 2020 Tomic et al.

Attenuated subjective ratings and skin conductance responses to neutral and negative pictures in non-psychopathic mentally disordered offenders with various diagnoses
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Altered autonomic arousal in relation to offending behavior has mainly been investigated in subjects with varying degrees of psychopathic traits. The present study sets out to investigate subjective ratings and skin conductance responses (SCRs) in mentally disordered offenders with various diagnoses but without psychopathy, specifically recruited from the forensic psychiatric system. Two subgroups were investigated; an antisocial group with antisocial personality disorder (APD) or antisocial traits (n=16) and a non-antisocial group with various diagnoses (n=25), in relation to a healthy non-criminal control group (n=20). All participants were male. SCRs and subjective ratings of arousal and valence were measured for neutral and negative pictures from the International Affective Picture System (IAPS). The offenders showed significantly lower SCRs and subjective ratings than the control group. Moreover, there was no significant difference between antisocial and non-antisocial offenders, indicating that antisocial behavior might not be a differential factor. Thus, attenuated emotional responses may be a characteristic shared by mentally disordered offenders overall.
