Adolescent Depression fNIRS Data During Verbal Fluency Task

A study of 273 adolescents aged 14–16 years with major depressive disorder, including 110 without and 163 with psychotic symptoms. The dataset contains functional near-infrared spectroscopy (fNIRS) recordings of oxy- and deoxyhemoglobin from six frontal brain regions during a 60-second verbal fluency task, along with clinical severity scores. It was authored by Gang Liu and last updated on 2026-06-02.

Use Cases

• Classifying psychotic vs. non-psychotic depression based on prefrontal hemodynamic responses.
• Analyzing correlations between brain activation patterns and clinical severity scores like the Kutcher Adolescent Depression Scale.
• Testing the discriminative power of specific fNIRS channels for psychiatric subgroup identification using ROC analysis.

Strengths

• Includes data from 273 adolescent participants, a substantial sample size for a clinical study.
• Clinical severity is indexed using two standardized scales (KDAS and BPRS) with reported median scores.
• Hemodynamic data is recorded from 53 fNIRS channels across six predefined frontal regions of interest.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The study lacks a healthy control or other psychiatric comparison group, limiting diagnostic specificity as noted in the conclusions.
• The dataset is very small at 90.5 KB, indicating limited scope, likely containing summary results rather than raw time-series data.
