The Comprehensive Assessment of Psychopathic Personality (CAPP) is a lexically based conceptual model of psychopathy. Despite widespread use in research settings, the Lexical Rating Scale for the CAPP (CAPP-LRS) requires an advanced reading level for completion. The present study is the first to evaluate the content validity of the CAPP-Basic, a lexically simplified version of the CAPP-LRS designed for use with individuals possessing lower verbal skills. Symptoms were rated by mental health professionals (N = 121). Findings were largely in line with results of previous studies, indicating good content validity of the CAPP-Basic at the domain and symptom level.

Triarchic Model

Can the components of the triarchic model of psychopathy (i.e., boldness, meanness, disinhibition) be operationalized using the item pool comprising the Comprehensive Assessment of Psychopathic Personality (CAPP) model? To address this question, the authors first derived CAPP-based triarchic scales using standard item-selection procedures and then examined the external correlates of these provisional scales in three archival data sets: (a) U.S. jail inmates administered the institutional rating scale version of the CAPP and (b and c) prototypicality ratings of the CAPP traits provided by Swedish forensic mental health professionals and U.S. probation officers. Although most research on triarchic constructs has relied exclusively on self-report inventories, the results suggest that the CAPP model can be reorganized to reflect boldness, meanness, and disinhibition and that its institutional rating scale items can effectively quantify these constructs using interview and file review data. Implications for future research on the measurement and assessment of psychopathic traits are discussed.

Conceptual Clarity

The diagnosis of psychopathic personality disorder has salience for forensic clinical practice. It influences decisions regarding risk, treatability and sentencing, indeed, in certain jurisdictions it serves as an aggravating factor that increases the likelihood of a capital sentence. The concatenation of symptom that is associated with modern conceptions of the disorder can be discerned in early writings, including the book of Psalms. Despite its forensic clinical importance and historical pedigree the concept remains elusive and controverted. In this paper I describe an attempt to map the concept of psychopathic personality disorder—the Comprehensive Assessment of Psychopathic Personality (CAPP). I outline the processes used to create the concept map; I summarise evidence in support of the content validity of the map and describe different operations designed to operationalise the construct. It is only when conceptual clarity is achieved that valid operations and measures can be created. I end with a plea for more carefully considered application of statistical methods; applications that better fit the theoretical questions being posed.

The Comprehensive Assessment of Psychopathic Personality (CAPP) is a recently developed conceptual model of psychopathy designed to index the disorder across 33 personality traits. Although recent research has evidenced support for the CAPP model with respect to the convergent, criterion, and predictive validity of CAPP instruments, little work has examined the optimal internal structure and generalizability of the model and associated measures. The present study sought to elaborate on the construct validity and psychometric properties of the CAPP Lexical Self Rating Scale and determine the utility of the instrument across men and women, and individuals of Caucasian and East Asian descent. Within a large sample of self-identified offenders ( N = 1,414), we found strong support for a three-factor model comprising domains reflecting interpersonal dominance, behavioral disinhibition, and deficient emotional attachment. Analyses examining the generalizability of the model provide further insight into its applicability for diverse populations.

Instrument Adaptation

The Comprehensive Assessment of Psychopathic Personality–Lexical Rating Scale (CAPP-LRS) is a self-report instrument designed to index psychopathy according to the CAPP psychopathy framework. Developed with the expressed goal of advancing the state of knowledge regarding the specific features of psychopathy, the CAPP model and associated instruments have garnered increasing attention and support in the field. Despite the conceptual strength of the CAPP model, the advanced lexical structure of its primary research tool (the CAPP-LRS) has led researchers to question the utility of the instrument for use with some populations of interest (e.g., forensic/correctional and adolescent/young adult samples). The aim of the present work was to address this issue by creating a lexically simplified, though functionally equivalent, version of the CAPP-LRS to increase accessibility to critically relevant populations. A set of two studies ( N = 602) describes the adaptation protocol and the initial validation of the modified instrument.
