Encouraging direction, but not yet definitive.
This single-centre case–control study of 128 adolescents (64 with MDD, 64 controls) found that adolescents with MDD have significantly higher suicide probability scores, higher autistic trait scores, and greater depressive symptom severity than healthy controls. Within the MDD group, elevated autistic traits were associated with higher depressive severity after adjustment for age and gender; however, the study relies on self-reported and parent-reported scales rather than clinical suicide outcomes, and does not establish causation or prediction.
Single-centre case–control study. Adolescents aged 12–17 years: 64 with major depressive disorder diagnosed by K-SADS-PL and 64 psychiatrically healthy controls, recruited from an outpatient child and adolescent psychiatry clinic.. Intervention: Major depressive disorder (case group) versus psychiatric health (control group).. Compared with: Psychiatrically healthy controls.. n = 128. Single outpatient child and adolescent psychiatry clinic in Turkey..
Total CDI, SPS, and AQ-Adolescent scores were statistically significantly higher in the MDD group compared to healthy controls. Significant positive correlation observed between total CDI score and both total SPS and AQ-Adolescent scores in the MDD group. Log-transformed CDI total score was significantly higher in adolescents with MDD and elevated autistic traits than in those without elevated autistic traits, after controlling for age and gender.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians should be aware that adolescents with MDD who also present with elevated autistic traits may experience greater depressive severity and higher suicide risk scores; however, these are surrogate measures and do not yet establish whether screening for autistic traits in MDD improves suicide risk stratification or prevention outcomes.
A sound but limited single-centre case–control study with a modest sample showing significant group differences and correlations in a clinically relevant population, but using surrogate measures of suicide risk rather than hard outcomes.
As stated by the source record.

This study aimed to compare the autistic traits and probability of suicide in adolescents diagnosed with major depressive disorder (MDD) aged 12-17 years with psychiatrically healthy controls. The study was conducted with a total of 128 adolescents, including 64 patients with MDD and 64 psychiatrically healthy controls, recruited from an outpatient child and adolescent psychiatry clinic in Turkey. The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL) was administered to all subjects. Additionally, sociodemographic data were collected from each participant. The Suicide Probability Scale (SPS) and the Children's Depression Inventory (CDI) were completed by the participants, while parents filled out the Autism Spectrum Quotient-Adolescent (AQ-Adolescent) for their children. In the MDD group, the total scores of CDI, SPS, and AQ-Adolescent were found to be statistically significantly higher compared to the psychiatrically healthy controls. Additionally, a significant positive correlation was observed between the total CDI score and both the total SPS and the AQ-Adolescent scores in the MDD group. The log-transformed CDI total score, after controlling for age and gender, was found to be significantly higher in adolescents with MDD who had elevated autistic traits than in those who did not have elevated autistic traits. Our study's findings indicate that in comparison to controls, adolescents with MDD have a higher probability of suicide and autistic traits. Furthermore, adolescents with MDD and elevated autistic traits had significantly greater depressive symptom severity than those without elevated autistic traits.
