The project is a competence and collaboration project (CCP) funded by the Norwegian Research Council for four years (2023-2027). Representatives from five collaborating partners are involved in the project: Oslo University Hospital, the University of Oslo, the Norwegian Institute of Public Health, the Oslo Police District, and the Correctional Service. The main objective is to provide updated empirical knowledge about the development of violence risk over time and identify areas where cooperation between mental health services, police, and correctional services can be strengthened to better prevent violence among severely mentally ill individuals.
Active collaboration between researchers and practitioners is an essential characteristic of this project type, aiming to ensure that the generated knowledge meets the needs of practitioners in the field. The project has a broadly composed advisory group consisting of internationally leading researchers in criminology, law, and psychiatric epidemiology, as well as experienced representatives of the management level from the involved practice fields.
Background
Violence committed by severely mentally ill individuals constitutes a small proportion of the violence committed in a society. However, it still represents a significant societal challenge, generating much attention and calls for more effective prevention and better care for both individual patients and the surrounding environment. Police, correctional services, and mental health services share responsibility for preventing violence among individuals with severe mental illness. The three sectors increasingly express that the problems are growing in scope or severity and that there is a failure in coordination and collaboration between the services involved. Prisons experience an increasing proportion of mentally ill inmates who harm themselves or others and whom they do not have sufficient resources to manage. The police report an increase in their workload related to individuals with severe mental illness and potential for violence. Also, the proportion of patients convicted to mandatory mental health treatment is increasing. What are the factors contributing to this development? There are several hypotheses about possible mechanisms but little empirical knowledge to illustrate development over time and show if and how development of crime and illness are related. What are early signs of severe trajectories, and which conditions are protective?
Main Goal
The main objective of PreVio is to contribute with updated empirical knowledge about the development of violence risk over time and identify areas where cooperation between specialized mental health services, police, and corrections can be strengthened for better prevention of violence among severely mentally ill individuals.
Subgoals
- Subgoal 1: Examine changes in violent crime over time according to key legislative changes in the Penal Code and the Mental Health Care Act (Work Package 1)
- Subgoal 2: Identify subgroups and life course trajectories (Work Package 1)
- Subgoal 3: Investigate the effect of sociodemographic and psychological risk and protective factors for violence among individuals with mental illness (Work Package 2)
- Subgoal 4: Apply visual methods to the study of single cases to identify relationships between events and situations at the individual level (Work Package 3)
- Subgoal 5: Establish cross-sectoral arenas for knowledge exchange and communication (Work Package 4)
Implementation
PreVio employs a multidisciplinary mixed-methods approach where quantitative data from two existing datasets are combined with a visual method for qualitative exploration of individual cases. The data sources included in the project are:
- a population-wide registry linkage (ForenPsych, N ≈ 9 million) with information on severe mental disorders, violent crime, and sociodemographic factors,
- a clinical dataset (sTOP, N ≈ 200 participants) comprising a range of psychological characteristics and individual risk and protective factors,
- case-based life history plots from a smaller sample of patients/inmates.
Funding
The project is funded by the Research Council of Norway (SAMRISK-2) (project number 341355) for the period 2023-2027.
