Depressive symptoms and age of alcohol use onset interact to predict suicidal ideation

Abstract Distal risk factors of alcohol use may increase suicidal ideation in the presence of proximal risk factors, such as depressive symptoms. We tested whether depressive symptoms and age at onset of alcohol use interact to predict suicidal ideation in 500 individuals (67% men; 68% Black/African American) under criminal justice supervision. Regression analysis revealed that age of onset negatively associated with suicidal ideation only at average and high levels of depressive symptoms while controlling for suicide attempt history. Clinicians may consider individuals with an early age of onset of alcohol use and current depressive symptoms at risk for suicidal ideation.
