Although mental illness has a demonstrated link with violence, the prevalence of targeted (planned and goal-directed) violence perpetrated by individuals with mental illness and its association with psychiatric symptoms is relatively unexplored. File information was compared for all 293 individuals found not criminally responsible due to mental illness in British Columbia between 2001 and 2005, of whom 19% had committed targeted violence. Most individuals with targeted offenses displayed at least one warning behavior before their offense (93%); all displayed delusions and approximately one third exhibited hallucinations. Compared to individuals who perpetrated non-targeted offenses, the individuals with targeted offenses displayed greater proportions of threats/criminal harassment, had female victims, displayed a psychotic disorder and/or personality disorder, and displayed delusions during the offense. This implies that severe psychiatric disorders do not preclude the perpetration of planned violence and suggests that exploring symptoms of mental illness that may be proximally indicative of targeted violence is important in preventing future acts., (© 2023 The Authors.

Three studies examined the psychometric properties of a new scale, the Forensic Stigma Scale (FSS), designed to measure public stigma of forensic patients. In Study 1, the initial item pool was derived to measure three components of stigma (stereotypes, prejudice, discrimination). An EFA (n = 218) identified a two-factor model with 12 items. In Study 2, this two-factor solution was confirmed using CFA with a separate sample (n = 326) which had good-excellent fit indices. All 12 items loaded (> 0.40) on the two latent factors (Dangerousness/Unpredictability [7 items] and Responsibility/Blame [5 items]) identified in the EFA. In Study 3, using the combined samples from the previous two studies, the 12-item FSS showed promising internal consistency reliability (0.75-0.80) and demonstrated satisfactory-good criterion validity; the scale was moderately correlated with a similar construct and was able to differentiate individuals who did and did not have specific education on forensic psychology. IRT analyses demonstrated that both subscales had discrimination parameters in the moderate-high range (α = 1.03 to 2.54), though the threshold parameters (b i ) on the Dangerousness/Unpredictability subscale showed better distribution across trait levels. Overall, the 12-item FSS demonstrates strong psychometric properties, especially the Dangerousness/Unpredictability subscale. The scale may provide clinical and empirical uses for measuring public stigma of forensic patients., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

Background: The public often perceives the insanity defense as a "get out of jail free card". Conversely, several studies demonstrate the substantial control imposed upon these defendants. This study compares Review Boards decisions regarding people found not criminally responsible on account of mental disorder (NCRMD) to criminal courts decisions regarding convicted offenders for similar offenses in Canada., Method: Detention, using logistic regression, and duration under detention and supervision, using Cox regression, were compared between a cohort of 1794 individuals found NCRMD in three Canadian provinces (Quebec, Ontario, and British Columbia) between 2000 and 2005 followed until 2008 from the National Trajectory Project and a national sample of 3,20,919 Canadians convicted of criminal offense from Statistics Canada's Criminal Court Survey., Results: Individuals found NCRMD are 3.8 times (95% CI 3.4-4.3) more likely to be detained than convicted offenders as well as 4.8 times (95% CI 4.5-5.3) and 2.9 times (95% CI 2.6-3.1) less likely to be released from detention and supervision, respectively. One year after the verdict, 73% of the NCRMD accused were still under legal supervision and 42% were still in detention, whereas these proportions were, respectively, 41 and 1% for their convicted counterparts. Interaction effects show that sex, age, jurisdiction, number of offenses, and severity of crimes committed have a differential impact on decisions applied to NCRMD accused compared to convicted persons., Conclusion: Contrary to popular perceptions, the insanity defense is not a loophole. Differences as to factors influencing the trajectories of the two samples confirm that Review Boards are able to distance their practices from the criminal courts and can set aside, at least in part, the principles of proportionality and punitiveness governing the traditional sentencing practices., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Martin, Charette, Leclerc, Seto, Nicholls and Crocker.)

This study sought to examine the potential impact of defendant gender and mental illness type on Canadian juror decision making by manipulating the gender (man, woman) and mental illness (substance abuse disorder, schizophrenia, bipolar, depression) of the defendant in a second-degree murder case involving an insanity plea. Participants read a trial transcript that included definitions of second-degree murder and the not criminally on account of mental disorder (NCRMD) defense. Participants then provided a verdict (guilty or NCRMD) and completed various scales measuring attributional judgments, perceptions of the defendant, and perceived dangerousness. Contrary to expectations, NCRMD was chosen over a guilty verdict in the majority of cases. Findings also indicated that participant decisions and perceptions regarding defendants diagnosed with substance abuse disorder differed from the other mental illness groups. The gender of the defendant had an influence on participants' perceptions of internal attributions, and the perceived stability of criminal behaviors. Results suggest that perceptions of mental illness influence verdicts in NCRMD cases, and that defendant gender plays a role in participants' perceptions of defendants. These findings contribute to the scarce literature on mental illness in the Canadian court system. Future research should examine the interaction between juror gender, defendant gender, and mental illness in insanity cases., (Copyright © 2016 Elsevier Ltd. All rights reserved.)
