Adolescent suicide or self-injury risk assessment early-warning model building method

Abstract

The invention provides an adolescent individual self-injury or suicide risk assessment method comprising the following steps: collecting risk prediction factor information of persons to be assessed through questionnaire survey; building a psychological behavior characteristic vector according to the risk prediction factor information, and dividing the persons into a training set and a test set; establishing an individual suicide or self-injury behavior probability model according to the training set; establishing a risk scoring function according to the individual suicide or self-injury behavior probability model; and inputting the test data set to a risk assessment early-warning model to verify the performance of the risk assessment early-warning model. By adopting the risk assessment early-warning model built based on the computer technology, individuals and groups with risk of suicide or self-injury can be predicted effectively, and then psychological counseling is offered to the individuals and groups so as to effectively reduce the occurrence of suicide or self-injury behavior.
