Anecdotally, combatants report to feel appealed by the perpetration of violence.
This trait is also called combat high or appetitive aggression. Thus far, appetitive
aggression is only assessed through self-report. The proposed PhD project intends
to create an objective marker for appetitive aggression through epigenetic
analyses. I will implement this by applying Elastic Net multivariate regression
modelling following the model of the epigenetic clock by Horvath (2013). I will
use already existing DNA data from former child soldiers and abducted children in
Uganda (N = 1012), and from active soldiers in Burundi (N = 200, two
measurement points). DNA methylation profiles from these saliva samples have
already been generated using Infinium MethylationEPIC BeadChips (Illumina). In
addition, I will also have access to collected data from other groups of excombatants
(DR Congo, N = 400; Burundi, N = 390) and active soldiers (Burundi,
N = 281, two measurement points) which will be analysed over the course of the
project. With these data sets I will create and test an epigenetic reference panel
for appetitive aggression.
Subsequently, the model will then be tested in independently collected DNA
samples. Furthermore, I will investigate which external changes impact the
characteristics of appetitive aggression on a molecular level. This novel approach
will help to improve and to test the effectiveness of interventions regarding
appetitive aggression in an objective manner.
