Abstract
Suicide is a significant public health issue, causing huge impacts on individuals as well as their families. Psychiatric stressors are major suicide risk factors and can profoundly impact a person in many aspects. In order to facilitate the understanding of psychiatric stressors and the associated symptoms, we extracted stressors and symptoms terms from major online knowledge repositories and psychiatric clinical notes. The current vocabulary collection contains 1,292 psychiatric symptoms and 715 psychiatric stressors, which was leveraged to study the associations between stressors and symptoms in a corpus of suicide related tweets. Using Chi-Square test with Bonferroni correction, 3,500 symptom–stressor pairs were identified with significant association (p-value<0.01).
