Briere J, et al. - Researchers examined a stratified sample of 679 individuals from the general population for the multivariate relationship between suicidality and three potential etiologic variables (depression, posttraumatic stress, and reactive avoidance). Individuals reporting suicidal behavior in the previous 6 months (58%) and those reporting recent suicidal ideation alone (40%) had higher odds of lifetime exposure to trauma or another very unpleasant event, vs those with no recent suicidal thoughts or behaviors (26%). Two independent sources of variance were identified: the first loading on both suicidal ideation and behavior, predicted by depression, posttraumatic stress, and reactive avoidance, and the second indicating a unique relationship between suicidal behavior and reactive avoidance alone. In this study, multidimensional etiology of suicidality is suggested. It points to a significant variant of suicidal behavior that seems not related to depression or posttraumatic stress but may exhibit emotional dysregulation and subsequent distress reduction behaviors.
