Primary outcome
Participants complete a semi-structured interview, two neuropsychological test
(for novelty effect), and aggression questionnaires. Furthermore, researchers
use data from judicial records.
Secondary outcome
Not applicable.
Background summary
Since Traumatic Brain Injury (TBI) is supposed to be a risk factor for
aggressive behaviour, it may be important to know if a prisoner suffers from
TBI. Therefore, the aim of this study is to examine the prevalence of TBI among
male prisoners in the Penitentiair Psychiatrisch Centrum (PPC), using a
semi-structured interview (the Ohio State University Traumatic Brain Injury
Identification Method (OSU-TBI-ID)), in relation to the type of crime and
aggression. Diagnosing TBI in a forensic population is difficult and can take a
lot of time because medical records often are not available or difficult to
obtain. Self-report isn*t always reliable and mild TBI isn*t always detectable
using standard neuropsychological testing. The Test of Attentional Peformance
2.3.1 (TAP 2.3.1) measures different kinds of attentional functions. The
subtests *alertness* and *flexibility* can measure the novelty effect (NE).
Both tests have to be done twice. NE is a sensitive measure for TBI in a
forensic population. In this study it is also investigated if the TAP 2.3.1 can
distinguish between prisoners with and without TBI as measured with the
OSU-TBI-ID. When this is the case, the TAP 2.3.1 can be used in diagnostics.
Furthermore, the aim of this study is to examine whether increasing NE
correlates with increasing aggression and increasing severity of crimes. This
is of use by evaluating the ecological validity of NE.
Study objective
A. To gain more knowledge about the prevalence of TBI in male prisoners in the
PPC and the relationship of TBI with violent crime and aggression. We expect
that TBI is more common in violent offenders than in non-violent offenders.
More specific, we hypothesize that TBI, as measured by the OSU-TBI-ID, is
predictive of a higher number and more severe violent crimes. Also, we
hypothesize that TBI is predictive of more impulsive aggressive behaviour as
measured by the Novaco Anger Scale-Provocation Inventory (NAS-PI) and the
Reactive Proactive Questionnaire (RPQ).
B. To investigate if two subtests of the TAP 2.3.1, alertness and flexibility,
are useful as an instrument to discriminate between prisoners with and without
TBI as measured by the OSU-TBI-ID. We hypothesize that TBI leads to an
increased novelty effect and, therefore, prisoners with TBI will have
significant higher scores on the task compared to prisoners without TBI. Also,
we hypothesize that increasing NE correlates with an increasing number and more
severe violent crimes and increasing impulsive aggressive behaviour as measured
by the Novaco Anger Scale-Provocation Inventory (NAS-PI) and the Reactive
Proactive Questionnaire (RPQ).
Study design
A. The prevalence part of the study has a cross sectional design.
B. The explorative part of the study has a cross sectional design.
Study burden and risks
The study group is estimated to be representative for Dutch, male offenders in
the PPC. Since this is a non-invasive study, the risks for participants are
low. Participation is fully voluntarily. They may benefit from participation in
the study by gaining more insight in their cognitive skills.
