Background summary
PP6-10: Constructs such as 'Metacognition', 'Theory of Mind, 'Empathy' and
'Mentalizing' are often implicated as contributors to the risk of violence in
persons diagnosed with a psychotisc disorder. Using several interviews,
questionnaires, psychological tests and a computer task these domains will be
measured in persons with a psychotic disorder that are currently in treatment
at a forensic clinic. This data will be compared with the existing baseline
data of persons with a psychotic disorder (between-group) that have not been
convicted of a felony, and correlations within the sample will be analysed
(within-group). This way we hope to contribute to our understanding of these
factors, construct a model of the most significant risk factors so as to
contribute to future risk assessment, and to use these new insights to guide
future treatment choices.
Study objective
P.11: This study seeks to contribute to our understanding of factors which
contribute to violence in persons diagnosed with psychotic disorders, in order
to improve clinical risk assessment and guide treatment choices.
Study design
Case-control study
Study burden and risks
Participants will be invited for an intake, during which the MINI-PLUS
interview is conducted in order to verify their diagnosis. This is estimated to
take 30 minutes.
A test battery will be delivered with an estimated time of 2 hours and 22
minutes. As the time such a battery requires is very dependent on the
participant (neurocognitive deficit, reading speed, familiarity with computers)
breaks can be scheduled upon request of the participant, or when deemed
necessary by the research assistant based on their observations of the
participant's well-being. Additionally, the test battery may be spread out over
multiple sittings.
