Detecting Multiple Mental Health Disorders with Large Language Models

Artificial Intelligence systems have become useful in many sectors, including healthcare. In this paper, we focus on detecting signs of mental health disorders from social media texts. This can be used to direct patients to consult a healthcare professional, while on waiting lists, or for post-monitoring. The performance of the current algorithms for detecting multiple disorders is limited. We propose a new method to increase performance by including target-domain knowledge for each type of mental health disorder (for nine disorders). We used this information to select the best training examples to include in our carefully engineered prompts for performing few-shot learning. We show that the results improved when compared to zero-shot learning based on Large Language Models and when compared to state-of-the-art results on the same test set.
