Abstract
At least five symptoms must occur for a DSM diagnosis of major depressive disorder (MDD), one of which must be sadness or anhedonia. The present study is the first known investigation of the implications of the presence or absence of these prioritized symptoms on symptom expression and clinical characteristics among 564 young adults with MDD. Differences in symptom expression and clinical characteristics occurred among MDD participants with sadness relative to those without sadness as well as among MDD participants with anhedonia relative to those without anhedonia. Differential symptom expression could have important implications for the etiology, prevention, and treatment of MDD.
