Abstract

This study examines whether distinct symptom profiles, patterns of comorbidity, and suicidal symptoms uniquely characterize individuals diagnosed with double depression (DD) by comparing Brazilians with DD to those with major depressive disorder (MDD). One hundred forty two psychiatric outpatients (ages 20-77 mean=48.8, S.D.=13.2; DD, n=23; MDD, n=119) participated in structured diagnostic interviews and completed self-report measures of depressive symptoms, suicidality, and family history of mental disorders. Patients with DD exhibited a more severe symptom profile than those with MDD, as evidenced by a higher number of depressive symptoms and more intense suicidal ideation. They also appeared to be qualitatively different from individuals with MDD, as evidenced by distinct comorbidity patterns, quality of life reports, and anhedonic features. These results may be important in understanding the phenomenology of DD in psychiatric outpatients by informing diagnostics, psychotherapy, and psychotherapeutic treatment of DD.
