Task-evoked eye movements as candidate digital biomarkers of depression severity in adolescents and young adults

Key points

• Objective digital measures of depression severity could complement conventional symptom assessments and facilitate more timely clinical evaluation.1
• In this single-center, cross-sectional study, 155 participants aged 14--20 years completed emotional-spatial free-viewing and memory-guided recall tasks and were stratified by 17-item Hamilton Depression Rating Scale scores.1
• We examined 19 prespecified eye-movement features across six task-informed domains using covariate-adjusted ordinal-trend models.1
• Together, these findings identify altered visual exploration and memory-guided gaze control as candidate digital biomarkers of depression severity, rather than generalized negative attentional bias.1
