Revisión sistemática de la relación entre sintomatología postraumática y conducta suicida.

Evidence has consistently demonstrated the relationship between post-traumatic stress disorder (PTSD) and suicide. However, there is little research related to the differential relationships between the PTSD symptom clusters (avoidance, re-experiencing, hyperarousal and negative alterations in cognitions and mood) and risk and suicidal behavior. The present systematic review studies the relationship between these post-traumatic symptom clusters and suicidal behavior (suicidal ideation and suicide attempts). The review includes 20 articles from the databases PsycINFO, PsycARTICLES and Web of Science. Results indicate that hyperarousal significantly predicts suicidal ideation in 53.33% and suicide attempts in 42.85% of the studies reviewed. Reduction of hyperarousal symptoms should be considered a priority objective in the development of therapeutic interventions to reduce suicide risk in people with post-traumatic conditions or diagnosed with PTSD.
