Tsang, S., Salekin, R.T., *Coffey, C.A. & Cox, J. (2017). A comparison of self-report measures of psychopathy among non-forensic samples using item response theory analyses. Psychological Assessment, 30, 311-327.
This study investigated how well components of the psychopathy trait are measured among college students with the Levenson Self-Report Psychopathy Scale (LSRP), the Personality Assessment Inventory–Antisocial Features Scale (PAI ANT), the Psychopathic Personality Inventory–Short Form (PPI-SF), and the Self-Report Psychopathy Scale-II (SRP-II). Using Samejima (1969)’s graded response model (GRM), the subscales were found to vary in their ability to measure the corresponding latent traits. The LSRP primary psychopathy factor is more precise in measuring the latent trait than the secondary psychopathy factor. The PAI ANT items show coherent psychometric properties, whereas the PPI-SF factors differ in their precision to measure the corresponding traits. The SRP-II factors are effective in discriminating among individuals with varying levels of the latent traits. Results suggest that multiple self-report measures should be used to tap the multidimensional psychopathy construct. However, there are concerns with respect to using negatively worded items to assess certain aspects of psychopathy.

Cox, J., *Stanziani, M., *Coffey, C. A., & *deLacy, R. D. (2018). LGB Q&A: An investigation of the influence of sexual orientation on professional practice among LGBQ-affiliated forensic mental health professionals. Professional Psychology: Research and Practice, 49, 255-263.
Recent decades have seen an increase in research examining the experiences of Lesbian, Gay, Bisexual, Queer, and other-identifying (LGBQ) individuals in the workplace, including surveys and empirical studies exploring how an individual’s sexual orientation influences their work, instances of workplace discrimination due to sexual orientation, and the impact of antidiscrimination legislation in changing workplace culture. However, research has yet to examine the experience of LGBQ-identifying forensic mental health professionals. A survey of 37 forensic psychologists and psychiatrists who self-identified with the LGBQ community found half of all participants viewed their sexual orientation as impacting their professional identity in some way. Qualitative analyses suggest this may include an interest in research about or a desire to work with LGBQ-identifying individuals. Although one third of the participants in this study reported they did not believe there was LGBQ related prejudice or discrimination in the field of forensic mental health, 81% of participants reported experiencing some form of prejudice/discrimination. Further, over half of all participants reported changing their professional practice, physical appearance, and/or behaviors to influence others’ perceptions of their sexual orientation. In total, these data suggest LGBQ-identifying forensic mental health professionals may simultaneously feel as though the field is particularly accepting of nonheterosexuality while also identifying ways in which their sexual orientation impacts their workplace behaviors and environment. Ruiz, M., Hopwood, C., Edens, J.F., Morey, L.C., & Cox, J. (2018). Initial development of pathological personality traits domain measures using the Personality Assessment Inventory (PAI). Personality Disorders: Theory, Research, and Treatment.
This study set out to create measures of the five personality disorder trait domains outlined in Section III of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (American Psychiatric Association, 2013) from the Personality Assessment Inventory items (Morey, 2007). Rasch rating scale model analyses and classical test theory analyses were applied to existing data sets (N = 3,877; community, clinical, offender, college) to identify relevant items. Five scales were created that had acceptable unidimensionality and generally conformed to Rasch model expectations. The ability of the items to cover the underlying construct and their differential item function by sex were acceptable, though a few of the proposed scales had weaknesses in these areas. Internal consistency was acceptable for all scales and the factor structure was generally consistent with expectations, but some scales had concerning cross-loadings. Preliminary analyses demonstrated validity of the scales in relation to history of mental health treatment/current symptoms, substance abuse, and, for one scale, violent rearrests. There were small-to-moderate associations with noncorresponding traits, suggesting a degree of saturation with general personality impairment. The relevance of the proposed scales for the assessment of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition personality disorder is discussed. |
