76 patients with insomnia disorder were randomized into intervention and control groups for a 4-week trial. The dataset likely contains Pittsburgh Sleep Quality Index scores, depression/anxiety/stress scale scores, and functional near-infrared spectroscopy measurements of oxy-haemoglobin concentration and functional connectivity. The data was uploaded by Qin Shi in April 2026.

Use Cases

• Analyzing the correlation between sleep quality improvement and prefrontal functional connectivity changes based on fNIRS data.
• Comparing the efficacy of combined music and tDCS therapy versus music alone based on PSQI and psychological scale scores.
• Investigating cortical activation patterns in specific brain regions like the medial prefrontal cortex during a verbal fluency task.

Strengths

• Data originates from a randomized controlled trial with 76 participants, providing a structured experimental design.
• Includes multiple validated clinical assessment scales (PSQI, SDS, SAS, PSS-14) and objective neuroimaging measures (fNIRS).
• The dataset is openly licensed under CC-BY-4.0, allowing for reuse and redistribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (18.9 KB), suggesting it may contain summary results rather than raw participant-level data.
