Swanson JW, Van Dorn RA, Swartz MS, Smith A, Elbogen EB, Monahan J. Alternative Pathways to Violence in Persons with Schizophrenia: The Role of Childhood Antisocial Behavior Problems. Law Hum Behav . 2007 Jun 30.

Abstract: Violence in schizophrenia patients may result from many factors besides the symptoms of schizophrenia. This study examined the relationship between childhood antisocial behavior and adult violence using data from the NIMH CATIE study. The prevalence of violence was higher among patients with a history of childhood conduct problems than among those without this history (28.2% vs. 14.6%; P < 0.001). In the conduct-problems group, violence was associated with current substance use at levels below diagnostic criteria. Positive psychotic symptoms were linked to violence only in the group without conduct problems. Findings suggest that violence among adults with schizophrenia may follow at least two distinct pathways—one associated with premorbid conditions, including antisocial conduct, and another associated with the acute psychopathology of schizophrenia.

Alter AL, Kernochan J, Darley JM. Transgression Wrongfulness Outweighs its Harmfulness as a Determinant of Sentence Severity. Law Hum Behav. 2007 August.

Abstract: When students suggest sentences for criminal offenders, do they rely more heavily on the harmfulness or on the wrongfulness of the offender's conduct? In Study 1, 116 Princeton University undergraduates rated the harmfulness and wrongfulness of, and suggested appropriate sentences for, a series of crimes. As expected, participants emphasized wrongfulness when choosing an appropriate criminal punishment. In Study 2, 33 Princeton undergraduates made similar ratings for violations of the University Honor Code, and rated their contempt for fabricated amendments to the Code that required sentencers to focus either only on harmfulness or only on wrongfulness. Again, sentences more closely reflected wrongfulness ratings, and participants were more contemptuous of the harmfulness-based proposal. We also consider the theoretical and practical implications of these findings for sentencing laws and policy.
