Abstract
Schema therapy is a physiological treatment technique for mental health issues. Based on the thoughts and behaviour, patients are classified to a schema mode which represents their current state of mind. Automatically classifying these thoughts and behaviours could improve detection of potential mental health issues as well as provide better and faster recovery. This research attempts to effectively generate schema-based stories that would be used to train machine learning models such as Support Vector Machines and Recurrent Neural Networks to classify stories from patients about their daily experiences. Experimental evaluation using the OpenAI GPT-2 model shows that it is possible to generate correct and coherent stories with a minimum of 58.7\% correctly classified samples even with sub-optimal data. Using conditional prefixed queries, the OpenAI GPT-2 model can generate stories that resemble the given data but with little to no similarity in terms of BLEU scores.
