The Comprehensive Assessment of Psychopathic Personality Symptom Rating Scale (CAPP SRS) is a relatively new measure of psychopathic personality disorder (PPD) based on the CAPP concept map of psychopathy. To investigate the CAPP SRS, we identified the most plausible formal test structure for the test using the framework proposed by Slaney and Maraun, identified an appropriate quantitative characterization of that test structure, and then statistically evaluated it based on analysis of CAPP SRS data collected from a multisite sample of 314 adult male correctional offenders and secure hospital patients in Scotland and England. Overall, the CAPP SRS survived falsification when observed test data were compared to expectations based on the unidimensional monotone latent variable or UMLV model of Holland and Rosenbaum. CAPP SRS composite scores calculated consistent with the UMLV model had good measurement precision and good external validity with respect to scores on an established test of PPD. The findings provide provisional support for the test validity of the CAPP SRS and highlight the importance of theory-driven evaluations of test validity. [ABSTRACT FROM AUTHOR]

The relevance to women of common violence risk factors identified in men has in many instances yet to be established. Consequently, there is a reluctance to accept without question the application to women of practices relating to violence risk assessment and management developed from research into men. This study examines mental disorder in women who are violent in order comment on its relevance to the practice of violence risk assessment and management. A sample of 95 violent women in high secure prison and forensic psychiatric care were assessed. Structured assessments of Axis I and II mental disorders and psychopathy were undertaken on all women and conviction histories were recorded. Very high levels of psychiatric morbidity were noted and patterns in comorbidity were detected. Among Axis I conditions, psychotic disorders and disorders of mood co-occurred at a very high rate. Among the Axis II conditions, dimensional ratings of borderline personality disorder (PD) correlated with dimensional ratings of avoidant, dependent and paranoid PDs while ratings of antisocial PD correlated with those of narcissistic, histrionic and obsessive-compulsive PDs. Women who had been incarcerated for a major violent offence were four times more likely to have a diagnosis of borderline PD than women whose index offence was one of minor violence. A number of the findings reported are in contrast to those reported in similar studies of men. Findings suggest that practitioners are right to question the application to women of knowledge derived from research into men. The practice of violence risk assessment and management with women should emphasise the development of individual risk formulations and responding to psychiatric comorbidity should be the rule rather than the exception with this population.

In 2 studies, we examined the reliability and validity of an interpersonal measure of schizoid personality disorder (SZPD) based on nonverbal behaviors and interpersonal interactions occurring during interviews. A total of 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. Across both samples, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM-SZ) exhibited adequate reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM-SZ correlated in an expected manner with features of psychopathy and antisocial personality and with independent ratings of interpersonal behavior. We address implications for assessment of personality disorder.
