Abstrakt:	Background: Metadehumanization (the feeling of being considered as less than human by others) is a pervasive phenomenon in psychiatric states, notably promoting self-dehumanization and suicide antecedents. However, its role in suicidal ideations among patients with addictive disorders remains unexplored. We thus investigated the involvement of metadehumanization/self-dehumanization in suicidal ideations and suicidal thoughts interference in severe alcohol use disorder. Methods: We measured metadehumanization, suicidal ideations, and desire for social contact through questionnaires among 35 recently detoxified patients with severe alcohol use disorder (26 males). We measured animalistic/mechanistic self-dehumanization using an Implicit Association Task, and suicidal thoughts interference using a Stroop Task with suicide-related words. We performed regression analyses while controlling for depression/anxiety. Results: Animalistic self-dehumanization was positively associated with suicidal thoughts interference and with decreased desire for social interactions, such link being absent for metadehumanization or mechanistic self-dehumanization. Conclusions: This link between self-dehumanization and suicide-related factors suggests that a reduced sense of belonging to humanity is associated with self-harm antecedents. Results also emphasize the importance of using indirect measures to investigate sensitive variables, such as self-dehumanization and suicidal thoughts.
