||Abstract: Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might
underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear
relationship between these two variables, it is still unknown how ADHD facilitates violence proneness.
In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer
information about emotional regulation when individuals cope with stress. Furthermore, alexithymia
traits might be a strong candidate in explaining the above-mentioned emotional dysregulations.
Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and
without ADHD symptoms to that of controls (non-violent and unaffected), and we also assessed the
presence of alexithymia traits and their role in emotional regulation. Our data point out that ADHD
IPVAW perpetrators presented higher SCL and negative affect than controls, particularly during the
recovery period. Moreover, ADHD IPVAW perpetrators showed higher self-reported alexithymia,
and this variable was a good predictor of autonomic and psychological state dysregulations, even
after controlling for the effects of alcohol and drug misuse. Therefore, our study reinforces the
need to consider psychophysiological measurements when screening the therapeutic needs of
IPVAW perpetrators, due to their relatively low cost and the significant contents of their results.
Finally, we also highlight the key role of alexithymia in this violent population, which should be
considered when designing cognitive intervention training coadjutant to current psychotherapies for
