Abstract

Depression is a common mental disorder, which may lead to suicide when the condition is severe. With the advancement of technology, there are billions of people who share their thoughts and feelings on social media at any time and from any location. Social media data has therefore become a valuable resource to study and detect the depression of the user. In our work, we use Instagram as the platform to study depression detection. We use hashtags to find users and label them as depressive or non-depressive according to their self-statement. Text, image, and posting time are used jointly to detect depression. Furthermore, the time interval between posts is important information when studying medical-related data. In this paper, we use time-aware LSTM to handle the irregularity of time intervals in social media data and use an attention mechanism to pay more attention to the posts that are important for detecting depression. Experiment results show that our model outperforms previous work with an F1-score of 95.6%. In addition to the good performance on Instagram, our model also outperforms state-of-the-art methods in detecting depression on Twitter with an F1-score of 90.8%. This indicates the potential of our model to be a reference for psychiatrists to assess the patient; or for users to know more about their mental health condition. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
