A machine learning approach for predicting suicidal thoughts and behaviours among college students

Abstract Suicidal thoughts and behaviours are prevalent among college students. Yet little is known about screening tools to identify students at higher risk. We aimed to develop a risk algorithm to identify the main predictors of suicidal thoughts and behaviours among college students within one-ye...
