The aim of this study was to examine the presence of deliberate self-harm in young people and to examine differences in some individual characteristics in young people who self-harm and who do not self-harm. The study involved 334 students (73.4% girls) aged 18 to 31 years old. Students completed the Depression, Anxiety, and Stress Scale (Lovibond and Lovibond, 1995), the Emotional Regulation and Control Questionnaire (Takšić, 2003), the Voodoo Doll Self-Injury Task (Chester, Whitt, Davis, & DeWall, 2017), the Mental Health History Form (Boudewyn and Liem, 1995 according to Gratz, 2001) and the Deliberate Self-Harm Inventory (Gratz, 2001). According to the results of conducted research, 21.9% of students have a history of deliberate self-harm and most often begin with such behavior in adolescence. Deliberate self-harm usually occurs repeatedly, lasting several years and young people who do it use multiple different ways of self-harm. The results showed that young people who express intent to self-harm and young people with a history of self-harm have higher levels of depression, anxiety, and stress and less pronounced emotional regulation and control. Furthermore, higher levels of depression and anxiety were determined in young people who have a higher intensity and longer duration of deliberate self-harm, while no difference was found in the severity of stress and emotional regulation and control considering the intensity and duration of deliberate self-harm.
