Psychache, unmet interpersonal needs, childhood trauma and suicide ideation in young adults.

This 5-month, 2-wave study evaluated the mediating effects of psychache and unmet interpersonal needs on the relationship between childhood trauma and suicide ideation in 208 young adults, controlling for depression. Path analysis demonstrated that changes in depression, perceived burdensomeness, and thwarted belongingness mediated the relationship between childhood trauma and changes in positive suicide ideation, and that changes in depression and perceived burdensomeness mediated the relationship between childhood trauma and changes in negative suicide ideation. Results indicated the importance of assessing interpersonal needs, in addition to depression, for understanding the mechanism linking childhood trauma to suicide ideation in young adults.

Dimensionality of Suicide Behaviors: Results within Two Samples from Two Different Countries.

Across two countries and two languages, this research examined the multidimensional associations of suicide behaviors (i.e., life-time attempts, life-time communication of intent to others, life-time self-harming, life-time suicide notes, and current suicide ideation) and empirically relevant psychological risk factors (i.e., different facets of mental pain, perceived burdensomeness, thwarted belongingness, and acquired capability), controlling for depressive symptoms. For the Portuguese sample, two underlying dimensions emerged: an ideation dimension and a behavioral dimension, and for the Canadian sample, three dimensions emerged: an ideation dimension and two behavioral dimensions that can be viewed as a splitting of the Portuguese second dimension. Results highlight possible cultural differences between the two countries and that suicide behaviors should be viewed as a multidimensional phenomenon not as a one-dimensional continuum.

Exposure to Suicide in the Family: Suicidal Ideation and Unmet Interpersonal Needs in Young Adults Who Have Lost a Family Member by Suicide.

The aims of the present study were to compare a sample of individuals exposed to suicide in their families with a control group, on suicidal ideation, and to test possible potentiating effects for unmet interpersonal needs. Three hundred eighty-six young Portuguese adults participated. Two groups were defined: a group exposed to suicide in the family (n = 38) and a control group (n = 335). Groups differed significantly on suicidal ideation, on depressive symptoms, and on perceived burdensomeness and tended to differ on thwarted belongingness. Results from a hierarchical multiple regression analysis demonstrated that having lost a family member by suicide and perceived burdensomeness each provided a significant unique contribution to explaining variance in suicidal ideation when controlling for levels of depressive symptoms and having had a psychiatric diagnosis. The interaction between group membership and perceived burdensomeness provided a further enhancement to the statistical prediction of suicidal ideation.
