PTSD-in-the-wild dataset

Description

POST-traumatic stress disorder (PTSD) is a chronic and debilitating mental condition that is developed in response to catastrophic life events, such as military combat, sexual assault, and natural disasters. PTSD is characterized by flashbacks of past traumatic events, intrusive thoughts, nightmares, hypervigilance, and sleep disturbance, all of which affect a person's life and lead to considerable social, occupational, and interpersonal dysfunction.

Welcome to the page of the Labeled PTSD-in-the-Wild dataset. This is a database of videos of people With or Without PTSD. The dataset was collected to help study or detect PTSD using AI techniques. The dataset contains 613 videos of interviews of people with PTSD or not. It was constituted by firstly downloading YouTube videos of people who have gone through traumatic events and subsequently developed PTSD and are talking about their story. For the non PTSD counterpart, it is composed of interviews collected from YouTube of random celebrities. The dataset is perfectly balanced.

Composition

Apart from the labeling, other categories of information were collected. These are given below:
- Gender of the interviewee. Fig. 2b shows the distribution of the gender in the dataset across the labels With PTSD and Without PTSD.
- Degree of confidence, that is how confident the annotator is about the diagnosis.
- Type of trauma: The different types of trauma in dataset are: War veteran, Sexual assault, Plane crash, Terrorist attack, Domestic abuse, Car accident and other. Fig. 2a shows how the different types of trauma are distributed in the dataset.

Examples of video frames from the PTSD-in-the-wild dataset

Visual examples extracted from the dataset are shown here. It first shows two victims of War and plane crash who have developed PTSD. Then it shows two individuals without PTSD.

Figure 1: Four videos frames from PTSD-in-the-wild dataset of two subjects with PTSD ((a) and (b)) and two subjects without PTSD ((c) and (d)). (a) A woman who had PTSD after war. She was on a mission and suddenly a bomb exploded. She found out that she has PTSD in October 2004. (b) Man who suffered from PTSD after a plane crash. He was the captain of the plane. After the plane crush, his body was damaged a lot and he always felt guilty. (c) Dove Cameron answers the Web’s Most Searched Questions with WIRED autocomplete interview. Dove Olivia Cameron is an American singer and actress. She played a dual role as the eponymous characters in the Disney Channel comedy series Liv and Maddie. (d) Ken Jeong answers the Web’s Most Searched Questions with WIRED autocomplete interview. Kendrick Kang-Joh Jeong is an American stand-up comedian, actor, producer, writer and licensed physician

Training, Validation, and Testing

Our dataset consists of 317 videos of subjects with PTSD and 317 videos of healthy control subjects with no PTSD symptoms.
Two benchmarks are proposed for the evaluation and the comparison of new approaches for PTSD diagnosis and recognition. Then, for splitting the dataset into training, validation and testing sets, two strategies or partitions are given with the dataset:
Train/Validation/Test split: We randomly split the dataset into training, validation and testing sets with the percentages of 80%, 10% and 10%, respectively.
3-fold cross validation: To further evaluate the effectiveness of our baseline models and any new approach for video PTSD diagnosis, n-fold cross validation strategy with n=3 for are used for the splitting of training and testing sets and the three folds are given in the dataset.
