Psychopathy scores predict adolescent inpatient aggression

Area of Science:

• Psychiatry
• Forensic Psychology
• Developmental Psychology

Background:

• Adolescent psychiatric inpatients often exhibit aggressive behavior.
• Predicting aggression in this population is crucial for effective treatment.
• The role of psychopathy in adolescent aggression requires further elucidation.

Purpose of the Study:

• To investigate whether psychopathy scores predict aggressive behavior in adolescent psychiatric inpatients.
• To determine if psychopathy has incremental validity in predicting aggression beyond other clinical factors.

Main Methods:

• Prospective study of 72 adolescent psychiatric inpatients.
• Psychopathy assessed using Hare's Psychopathy Checklist-Revised within 3 days of admission.
• Aggressive behavior recorded by unaware clinical staff.

Main Results:

• Higher psychopathy scores significantly predicted higher frequencies of both reactive and instrumental aggressive behavior.
• Psychopathy scores remained predictive even after controlling for age, sex, socioeconomic status, and length of stay.
• Psychopathy demonstrated incremental validity in predicting aggression beyond clinical diagnosis and Millon Adolescent Clinical Inventory scores.

Conclusions:

• Psychopathy is a significant predictor of aggressive behavior in adolescent psychiatric inpatients.
• Clinical assessment of psychopathy can enhance the prediction of aggression in this population.
• Findings underscore the importance of considering psychopathy in the management and treatment of aggressive adolescents.
