Depressive Symptoms and Perceived Burdensomeness Mediate the Association between Anxiety and Suicidal Ideation in
Abstract:
A relationship between anxiety disorders and suicide-related behaviors has been demonstrated in adolescents, with a paucity of research examining mediators of this association. The present study hypothesized that anxiety would be associated with suicidal ideation via a serial mediation pathway through depressive symptoms and perceived burdensomeness and/or thwarted belongingness. A sample of 80 adolescents (68.8% female, 65.8% Hispanic), 13-19 years of age (mean = 16.93, SD = 1.66), completed 3 interviews as part of a randomized controlled trial. Results indicated a significant serial mediation from anxiety to suicidal ideation via depressive symptoms and perceived burdensomeness, but not thwarted belongingness. Clinicians and mental health service providers working with adolescents experiencing elevated anxiety should regularly assess for perceived burdensomeness and suicidal ideation.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
