Clinical Correlates of Major Depression in Psychiatrically Referred Youth With and Without Autism: A Controlled Study.
Major depression hits more than half of autistic youth in psychiatry clinics and rarely travels alone.
01Research in Context
What this study did
Usman and colleagues looked back at charts of youth sent to a psychiatry clinic. They compared kids with autism to kids without autism who were already diagnosed with depression. The goal was to see how often major depression shows up in autistic youth and what other problems tag along.
What they found
More than half of the autistic youth also met criteria for major depression. Only nine percent of the depressed, non-autistic youth had autism. When both conditions were present, the child usually carried extra diagnoses like anxiety, OCD, or even signs of psychosis.
How this fits with other research
The 55% depression rate lines up with Lugnegård et al. (2011), who saw a 70% rate in adults with Asperger syndrome. It also extends Joshi et al. (2013) by showing the heavy comorbidity starts in childhood, not just adulthood.
Chien et al. (2021) used insurance claims and likewise found mood disorders sky-high in autistic youth. Their numbers match even though one study used charts and the other used billing codes.
An apparent contradiction pops up with Porter et al. (2008). That small study hinted at lower mood-disorder rates, but their sample focused on substance-use clinics where depression is often missed. Different settings, different numbers—no real conflict.
Why it matters
If you screen an autistic client, flip over the depression checklist first. Expect classic DSM symptoms rather than “autism-only” signs. When depression is confirmed, keep digging—anxiety, OCD, and psychosis often ride along. Share this picture with the psychiatrist and the family so no treatable piece is missed.

OBJECTIVES: This study investigates the co-occurrence between autism spectrum disorder (ASD) and major depressive disorder (MDD) in pediatric populations, focusing on prevalence rates, comorbid psychiatric conditions, and their impact on clinical presentation and treatment outcomes. METHODS: We conducted a retrospective study of children and adolescents (ages 3-17) referred for psychiatric care to ambulatory care clinics (pediatric psychopharmacology [N = 2,307] and specialized autism spectrum disorder [N = 416] programs) at a major academic medical center. Psychopathology was assessed by the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic Version and the Child Behavior Checklist (CBCL). ASD was diagnosed using DSM criteria. RESULTS: Our findings revealed a co-occurrence and bidirectional relationship between ASD and MDD (55% of ASD patients had MDD, while 9% of MDD patients had ASD). The symptom profile of depression in youth with ASD was consistent with the typical DSM-based presentation. The burden of psychopathology was significantly greater in the presence of ASD and MDD comorbidity, and in particular the rates of comorbid anxiety disorders, OCD, and psychosis were significantly elevated. Social competence and global functioning were worse in the presence of ASD and MDD comorbidity. CONCLUSIONS: A high prevalence of comorbidity with MDD was observed in psychiatrically referred youth with ASD, with a clinical presentation of MDD that is typical of the disorder. Higher prevalence of anxiety disorders and psychosis was observed in the presence of ASD and MDD comorbidity. These findings underscore the need for comprehensive assessment and tailored interventions for children with co-occurring ASD and MDD, particularly in addressing anxiety and ensuring adequate access to mental health services.
