Globally, extensive research has been conducted on psychological trauma. The main intention of this scientific enquiry was to provide insights into the explanatory and etiological factors of such trauma, as well as provide measures of how to manage and treat it effectively. However, much of these research studies on psychological trauma have focused primarily on victims and witnesses of trauma, completely overlooking and neglecting offenders (perpetrators) and their trauma. This study set out to explore perpetrator trauma among juvenile offenders incarcerated for violent offenses. The study was qualitative in nature, using descriptive phenomenology to provide descriptive accounts of perpetrator trauma as experienced by the participants. A single case study design was utilized as a research design. The data were collected using semistructured audio-recorded individual interviews with 10 participants. The findings supported the existence of perpetrator trauma as the offenders experienced multidimensional consequences from their actions. They experienced various symptoms related to or associated with their offenses and victims, including reliving symptoms, psychotic symptoms, psychogenic amnesia of the offense and the victims, and experienced a persistent negative emotional state. They also engaged in reckless and self-destructive behaviors, avoidant behaviors, and significant behavioral changes could be noted in their behavior.
