MAD: A Multimodal Physiological and Self-Reported Dataset for Anxiety Research

---

Overview

This dataset accompanies the IMWUT paper titled:
"MAD: A Multimodal Physiological and Self-Reported Dataset for Anxiety Research from a Low-to-Middle-Income Country."

The dataset captures physiological and self-reported responses from participants during a baseline condition and three anxiety-inducing activities (Speech, Group Discussion, Interview). Each activity consists of three phases:

• Anticipation – mental preparation before the task
• Activity – actual task performance
• Reflection – reflecting on task performance

Additionally, thinking data is included, representing participants’ preparation time for the speech and group discussion activities.

Data was collected using Shimmer ECG and Shimmer GSR kits at a sampling rate of 1024 Hz.

Participant Information

• Participant IDs range from 101 to 119.
• Some participant IDs are skipped due to:
  • Dummy participants included to simulate similar group settings in case participant refused to participate in the last minute. Their data is not shared.
  • Sensor failures, leading to unusable or incomplete recordings.

Please note:

• GSR data from the following participants should be excluded due to battery/sensor failures:
  [122, 123, 125, 126, 128, 129, 150, 170, 211]

File Descriptions

1. Data.7z

This archive contains participant-wise physiological recordings in two subfolders:

• ParticipantID_ECG/: ECG recordings
• ParticipantID_GSR/: GSR and PPG recordings

Each subfolder contains 12 .csv files representing various phases and tasks.

Columns:

• ECG Files:
  • time, Accel_X, Accel_Y, Accel_Z, ECG_LA-RA, ECG_LL-LA, ECG_LL-RA
• GSR Files:
  • time, Accel_X, Accel_Y, Accel_Z, Skin_Conductance, Skin_Resistance, PPG

2. Dataset_sample/

A small subset of the full dataset for preview/testing, includes:

• Data from Participant IDs: 101, 107

3. Self_report.csv

Self-reported anxiety levels collected:

• Before the study: SPIN questionnaire
• After each phase of each activity: custom anxiety ratings

Key Columns:

• P_Id: Participant ID

• SPIN_score: Pre-study social anxiety score

• PBS: Pre-baseline state

• ATSx_y, ASx_y, RSx_y: Anxiety scores for anticipation, activity, and reflection phases across the 3 tasks.

• Responses for each phase of each activity:

• ATS1_1 to ATS1_5 – Anticipation phase (Speech)

• AS1_1 to AS1_5 – Activity phase (Speech)

• RS1_1 to RS1_5 – Reflection phase (Speech)

• ATS2_1 to ATS2_5 – Anticipation phase (Group Discussion)

• AS2_1 to AS2_5 – Activity phase (Group Discussion)

• RS2_1 to RS2_5 – Reflection phase (Group Discussion)

• ATS3_1 to ATS3_5 – Anticipation phase (Interview)

• AS3_1 to AS3_5 – Activity phase (Interview)

• RS3_1 to RS3_5 – Reflection phase (Interview)

Note on Scoring:

The following questions needs to be reverse-coded so that higher scores indicate higher anxiety:
PBS, ATS1_1, ATS1_2, AP1_2, RP1_2, ATS2_1, ATS2_2, AP2_2, RP2_2, ATS3_1, ATS3_2, AP3_2, RP3_2, and PS

4. ParticipantsDemographic.csv

Contains demographic details of each participant: - P_Id, Age, Gender, Location
