Previous studies on the general public’s perception of self-harm have focused on “nonsuicidal self-injury” (NSSI). Research on “deliberate self-harm” (DSH) as a form of impulsive non-lethal suicide has rarely been examined. To address the paucity of literature available within the Asian context, the present study examined the Thai general public’s perception toward acts of DSH in the context of failed suicide attempts. The central question of this study is “how do members of the Thai general public perceive impulsive acts of DSH with suicidal intent?” One hundred twenty-six Thais completed the attribution model of public discrimination questionnaire as adopted from a study by Corrigan et al. (2003). The present study employed two vignettes and compared male and female responses to acts of DSH. Assessments were made in regards to the attribution of: 1) personal responsibility beliefs (PRB); 2) affective responses (e.g., pity, anger, and fear); and 3) coercionsegregation responses toward persons who committed acts of DSH. Independent sample t-test showed a significant difference in Thai men and women’s attribution of helping responses.
