BACKGROUND: The association between schizophrenia and violence is an important issue in psychiatry. The impact of several factors (social cognition, neurocognition, alexithymia, emotion regulation capacity, and the therapeutic milieu) on aggression in schizophrenia creates an opportunity for the development and evaluation of novel treatments for aggression. Previous studies show that cognitive remediation training (CRT) and social cognitive training (SCT) help to decrease hostility. The parent study examined whether cognitive training leads to improvements in cognition emotion regulation capacity, and impulse control in participants with a history of impulsive aggression. The current study examined the effectiveness of CRT alone versus a combination of CRT and SCT in terms of emotion recognition and cognitive improvement. METHODS: The study recruited participants with schizophrenia or schizoaffective disorder with a past year history of at least one or more violent acts or a significant lifetime history of aggression as indicated by a score of 5 or more on the Life History of Aggression (LHA) interview from two inpatient sites (Manhattan Psychiatric Center and New York Hospital, Westchester Division). Participants were randomized to two groups of 36 one-hour sessions. Participants in the control group had 24 sessions of CRT (BrainHQ) and 12 sessions of Encyclopedia readings. Participants in the treatment group had 24 sessions of CRT (BrainHQ) and 12 sessions of computerized SCT (MindReading). To assess neurocognition, mentalizing, and facial affect recognition abilities, participants were administered the MATRICS Consensus Cognitive Battery (MCCB), Reading the Mind in the Eyes Task (Eyes Task), and the Emotion Recognition-40 (ER-40) respectively. Negative emotionality was captured using the Positive and Negative Affect Schedule (PANAS). RESULTS: The study data included 49 completers and 5 intent-to-treat samples, with 24 and 25 per group, respectively (CRT+ SCT and CRT alone). Results indicated no significant differences between groups at baseline. Significant overall improvements were observed in the ER-40 for all subjects across time (Mean Time 1 = 25.06 (SD = 25.023), Time 2 Mean = 30.86 (SD = 6.849), p < 0.001), the Mind in the Eyes Test - Revised (Time 1 Mean = 19.70 (SD = 7.407), Time 2 Mean = 26.15 (SD = 7.830), p < 0.001), and the PANAS Negative affect Score (Time 1 Mean = 29.40 (SD = 11.836), Time 2 Mean = 18.47 (SD = 2.688), p < 0.001). Both cognitive groups showed improvements from baseline on the composite cognition score of the MCCB composite (F (1,47)=74.51, p |
