Summary

The purpose of the study is to examine the effects of cognitive training on emotion regulation, impulse control, and aggression in people with schizophrenia. The study compares a combination of computerized cognitive remediation and social cognition training (CRT+SCT) to cognitive remediation alone (CRT). Study outcomes include multiple measures of aggression, emotion regulation, impulse control, cognition, and symptoms.

Detailed description

Neurocognitive and social cognitive impairments are contributors to negative emotionality and impulsive aggression in people with schizophrenia. Impulsive aggression poses several challenges to the care of people with schizophrenia. These include a greater risk of rehospitalization and longer hospital stays, involvement with the criminal justice system, and increased risk of recidivism. The investigators recently found that schizophrenia patients with aggression history experienced improvements in neurocognition as well as decreased hostility/agitation and incidents of verbal and physical aggression after participating in cognitive remediation training (CRT). Based on these findings, it is hypothesized that improving neurocognition through CRT may have enhanced the capacity of schizophrenia patients to inhibit aggression through improved emotion regulation capacity and impulse control. It is also postulated that the addition of Social Cognition Training (SCT) to CRT would provide greater benefits on emotion regulation and impulse control over CRT alone. To test the hypotheses, the investigators will conduct a clinical trial that compares two configurations of cognitive training--CRT plus SCT versus CRT plus control computer games. The goal of the study is to examine the comparative benefits of the two configurations of cognitive training on outcomes that include neurocognition, social cognition, emotion regulation, impulse control, and reactive aggression. Participants assigned to the CRT plus SCT group will complete 24 hours of CRT and 12 hours of SCT. Participants assigned to the CRT only group will complete 24 hours of CRT and 12 hours of control computer activities. Emotion regulation, impulse control, and reactive aggression will be indexed using laboratory-based challenges. The investigators will recruit and characterize 90 study participants on demographic and clinical variables including age, gender, education, aggression history, and medications. Study outcome measures will be administered at baseline and posttreatment to participants randomized to the study groups. In a subsample of 32 patients, the study investigators will further examine changes in the neural network of emotion regulation and impulsivity before and after cognitive training.

Interventions

Type	Name	Description
BEHAVIORAL	Cognitive Remediation (CRT)	Study compares two configurations of cognitive training--computerized cognitive remediation versus a combination of computerized cognitive remediation and social cognition training. The cognitive remediation therapy group will complete computerized training activities in attention, memory, processing speed, problem solving, and executive functions.
BEHAVIORAL	CRT+ Social Cognition Training	Study compares two configurations of cognitive training--computerized cognitive remediation versus a combination of computerized cognitive remediation and social cognition training. The combined cognitive remediation and social cognition training group will complete computerized training that target neurocognitive functions, facial affect emotion recognition and mentalizing tasks.
