Neurai-VN, A Multimodal Digital Phenotyping Dataset for Depression and Anxiety Assessment in Free-Living Conditions

ABSTRACT: Despite affecting hundreds of millions of people globally, depression and anxiety remain understudied through passive sensing in low- and middle-income countries (LMICs), where severe clinical workforce shortages heighten the need for scalable monitoring. To address this gap, this study presents Neurai-VN, a high-resolution, multimodal dataset comprising passive sensing from wearable and smartphone devices, collected from 100 Vietnamese adults (aged 18–50) over two weeks. Participants were clinically screened and categorized into four mutually exclusive groups: depression, anxiety (generalized or social anxiety disorder), healthy controls, and other psychiatric conditions. The dataset contains (1) continuous wearable physiological signals and smartphone-derived behavioral data collected in real-world settings; (2) clinical labels, including DSM-5 diagnoses, symptom severity ratings, and validated self-report measures (PHQ-9, GAD-7, and daily mood assessments); and (3) standardized day-level features comprising 1,730 participant records across 14 sensing modalities, together with 2,096 validated self-report entries. Beyond its primary use, the dataset is anticipated to facilitate the discovery of mental health biomarkers and enable earlier detection of depression and anxiety, particularly in low-resource settings.
