Katarina Howner´s research group

Our research group, Forensic Behavioural and Neuroscience (FBN), conduct projects that in various ways relate to the link between mental disorder, violence and norm-breaking behaviors. By examining individual factors, such as psychiatric conditions and personality traits, as well as various environmental factors, we try to understand what leads to the use of force and other antisocial behaviors.

One goal is to identify risk and protection factors for violence in order to develop effective treatment methods adapted to the individual and thus prevent recidivism and, by extension, reduce the practice of violence. Our field is interdisciplinary and we have employees from different backgrounds and different fields, such as law, psychiatry, psychology and neuroscience.  


We work closely with the research group Forensic Epidemiology, with whom we also share research environment, and Rättsmedicinalverket (the National Board of Forensic Medicine).

Furthermore, we have active collaborations with Stockholms Universitet (Juridicum, Department of Psychology and SUBIC), Region Stockholm and Rättspsykiatrisk vård Stockholm, Institutionsstyrelsen (SiS), CELAM at Göteborgs universitet, Örebro universitet and Marie Cederschiöld högskola. 

Research projects

From Gene to Brain – Different Aspects of The Concept of Psychopathy (GeBra I & II)

GeBra I is a cross-sectional study involving clients within the Prison Service with the aim of investigating connections between specific candidate genes, personality traits and neuropsychological functions with a particular focus on psychopathic traits and behaviors. GeBra II is an ongoing brain imagingstudy aimed at investigating biological correlates in the brain linked to psychopathic traits in the normal population.

The triarctic model of psychopathy linked to fearless temperament and empathy (TriFE)

TriFE is a PhD project in the early 1990s where the aim is to investigate the ability to interpret and identify emotions and cardiac variability in the case of stress in inmates undergoing a forensic psychiatric examination.

Stockholm Forensic Psychiatry Project (SPRätt)

SPRätt is an ongoing study comparing  three different groups of individuals; those with psychosis spectrum diagnoses who have behaved violently, those with psychosis spectrum diagnoses who do not have ahistory  of violence, and healthy people in society. The project utilizes brain imaging in the form of functional near infrared spectroscopy (fNIRS), measures of skin conductance in various exercises and analysis of facial echoes during various cognition and social cognition tests.  The goal is to provide healthcare with tools to become better at identifying and treating individuals before acts of violence are committed.

Custody conflict and violence in connection with separation

This is a planned register study to highlight the health of children and parents in connection with a custody conflict. The purpose of the study is to identify the group of parents who, in connection with divorce, are in dispute over custody of joint children. Furthermore, the study aims to identify risk factors for custody conflicts and violence related to separation and divorce, as well as to investigate the short- and long-term effects of separation and divorce in families with underage children.

Longitudinal interview study conducted with girls taken into forced-care, on their experiences in care and treatment at SiS

This study aims to investigate the experience of care and treatment during the stay at SiS among girls, 15-18 years of age, placed in LVU treatment centers. The intention is to investigate how the girls perceive their situation as placed, and about the experience of being cared for in private. In addition, we will investigate what experiences the girls bring when they are discharged from SiS, by conducting follow-up interviews about six months after the girls have been discharged from SiS.

Partner violence

Within this theme, the conducted research projects aim to investigate the extent and characteristics of deadly partner violence in Sweden between 1990 and 2017. This project also includes studying other deadly violence against women  to investigate the development of deadly violence against women, as well as identifying typologies of perpetrators based on information on the perpetrator, victims and perpetrators. Another project, based on qualitative interviews, examines how partner rapists reason regarding problems of violence, need for help, susceptibility to and experience of interventions. The project is based on in-depth interviews with both prosecuted and volunteer applicants.
