Abstract
This study aimed to develop a predictive model for aggressive behaviors in hospitalized schizophrenia patients using machine learning algorithms. Researchers used cluster sampling to select 2037 patients (611 aggressive, 1426 non-aggressive), collecting data via questionnaires (General Condition Questionnaire, Insight and Treatment Attitude Questionnaire, Family APGAR, Social Support Rating Scale, Family Burden Scale) and the Modified Overt Aggression Scale (MOAS). Multi-layer Perceptron, Lasso, Support Vector Machine, and Random Forest algorithms were employed. Random Forest demonstrated the best predictive effect (AUC = 0.955), significantly outperforming the other models. A nomogram was created for clinical application, highlighting key factors such as Family APGAR, Insight and Treatment Attitude, disease duration, history of attacks, social support, medication adherence, age, and family burden.
