The Psychopathy Checklist—Revised (PCL-R) is a frequently used and well-validated measure of psychopathy but is relatively time-intensive and expensive to administer. The Psychopathic Personality Inventory (PPI) is a self-report measure that provides a less time-intensive and less expensive method for identifying psychopathic individuals. Using three independent samples and two different versions of the PCL (i.e., PCL-R, PCL:SV), the authors evaluated the extent to which the PPI and PCL overlap in their measurement of the psychopathy construct. Across three studies, PPI total and Factor 2 scores correlated moderately to strongly with PCL total and Factor 2 scores. Results for PPI and PCL Factor 1 scores were less positive. These findings raise important questions concerning the integration of results obtained using alternative psychopathy assessments.

The Psychopathy Checklist—Revised (PCL-R) is the most widely used measure of psychopathy in forensic clinical practice, but the generalizability of the measure to offenders with intellectual disabilities (ID) has not been clearly established. This study examined the structural equivalence and scalar equivalence of the PCL-R in a sample of 185 male offenders with ID in forensic mental health settings, as compared with a sample of 1,212 male prisoners without ID. Three models of the PCL-R’s factor structure were evaluated with confirmatory factor analysis. The 3-factor hierarchical model of psychopathy was found to be a good fit to the ID PCL-R data, whereas neither the 4-factor model nor the traditional 2-factor model fitted. There were no cross-group differences in the factor structure, providing evidence of structural equivalence. However, item response theory analyses indicated metric differences in the ratings of psychopathy symptoms between the ID group and the comparison prisoner group. This finding has potential implications for the interpretation of PCL-R scores obtained with people with ID in forensic psychiatric settings.

Concerns about low motivation to change among perpetrators of intimate partner violence (IPV) have heightened interest employing behavior change models with this population. In the present investigation, a new scale was developed, the Outcome Expectancies for Partner Abuse (OEPA) Scale, assessing the negative and positive outcome expectancies of partner abuse. Items were generated from statements made by IPV offenders during videotaped group therapy sessions. Among a clinical sample of 130 IPV perpetrators, item psychometric properties, factor structure, and subscale validity were examined. Results indicated generally good psychometric properties and a 2-factor solution, with the exception of 4 items subsequently removed from the negative expectancies scale. Significant associations were demonstrated between instrument subscales, readiness to change, and self-reported abusive behavior. Additionally, positive expectancy scores correlated with anger problems and relationship adjustment whereas negative expectancy scores correlated with partner-reported IPV. Potential uses of the OEPA and future directions for psychometric research are discussed.
Assessing the Affective Features of Psychopathy in Adolescence: A Further Validation of the Inventory of Callous and Unemotional TraitsRoose, Annelore; Bijttebier, Patricia; Decoene, Stefaan; Claes, Laurence; Frick, Paul J.

To provide an extended assessment of the affective features of psychopathy, Frick developed the Inventory of Callous and Unemotional Traits (ICU), which is a multi-informant questionnaire. Previous studies have provided initial support for the self-report version. The aim of the present study is to investigate the validity of self- as well as other report versions of the ICU and examine associations with measures of psychopathic traits, empathy, antisocial behavior and prosocial attitudes, reward and punishment sensitivity, and personality traits in a Dutch community sample of 455 adolescents (56% males). The results of the present study replicate and extend previous findings on the psychometric properties and the validity of the ICU in a sample of nonreferred youth. The three ICU subscales showed distinctive patterns of associations with key external criteria. Implications and directions for future research are discussed.

The Behavioural Status Index (BEST-Index) has been introduced into Dutch forensic psychiatry to measure change in risk level of future violence. The BEST-Index is a structured observational measure that assesses aggressive behavior, degree of insight, social skills, self-care, and work and leisure skills during inpatient treatment. Thus far, limited information regarding the psychometric properties of the Dutch version of the BEST-Index is available. The present study examines the reliability and validity of the Dutch BEST-Index in a sample of 291 mentally disordered offenders admitted to a forensic psychiatric hospital. Interrater reliability was investigated in a sample of 182 raters. Findings show that the Dutch BEST-Index can be used reliably and is significantly associated with risk of future violence and institutional aggression. Furthermore, this study revealed a different and clearer factor structure compared with the original one. Further research is needed to examine how these derived factors predict future recidivism.

The present study aimed at developing a new scale that operationalizes a hierarchical model of somatic complaints. First, 63 items representing a wide range of symptoms and sensations were compiled from somatic complaints scales and emotion literature. These complaints were rated by Belgian students (n = 307) and Belgian adults (n = 603). Exploratory factor analyses identified a gastrointestinal, cardiorespiratory, pain, temperature regulation, and fatigue factor. Next, the number of complaints was reduced to 18. Second, the short scale, called the Ghent Multidimensional Somatic Complaints Scale (GMSC), was administered to Belgian students (n = 735), Belgian adults (n = 664), and Turkish adults (n = 222). Confirmatory factor analysis confirmed that a higher-order model with five first-order and one second-order factor fitted best. Regression analyses demonstrated that the first-order factors were differentially related to anxiety, depression, anger, age, and gender. In sum, the GMSC scale offers the possibility to assess individual differences in somatic complaints from a hierarchical perspective.
Expanding the Construct Validity of the Relationship Profile Test: Associations With Physical Health and Anaclitic and Introjective TraitsHuprich, Steven K.; Wei Cheng Hsiao, ; Porcerelli, John H.; Bornstein, Robert F.; Markova, Tsveti

The authors examined the construct validity of the Relationship Profile Test (RPT) with respect to measures of two related constructs—physical health and well-being (functional health status), and depression-linked personality type (anaclitic vs. introjective). In Study 1, the authors administered the RPT, Depressive Experiences Questionnaire (DEQ), and Medical Outcomes Study Short Form (MOS SF-20) to 116 undergraduate students. In Study 2, the RPT, DEQ, and MOS SF-20 were administered to 110, mostly African American female, primary care outpatients. Destructive Overdependence was positively correlated with anaclitic and introjective trait scores in both samples. Dysfunctional Detachment was positively correlated with introjective scores in both samples and with anaclitic scores in the primary care sample. Healthy Dependency was negatively correlated with introjective scores in both samples and with anaclitic scores in the primary care sample. These studies support the construct validity of the RPT in ethnically diverse nonclinical and clinical samples, and extend previous findings documenting links between RPT subscale scores and scores on measures of other theoretically related constructs.

The purpose of the present study was to examine the psychometric properties, factorial structure, and validity of the Padua Inventory—Washington State University Revision and of the Padua Inventory—Revised in a large sample of patients with obsessive—compulsive disorder (n = 228) and with anxiety disorders and/or depression (n = 213). The five-factor structures of both revisions were not replicated. A 24-item revision, referred to as the Padua Inventory—Palatine Revision (PI-PR), was developed on the basis of both theoretical and statistical considerations. The PI-PR assesses six subscales: Contamination and Washing, Checking, Numbers, Dressing and Grooming, Rumination, and Harming Obsessions and Impulses. The results demonstrate that the PI-PR is a brief, psychometrically sound, and valid measure for the assessment of a broad range of obsessive—compulsive symptoms, which has important advantages over both previous revisions.
Traveling With Cognitive Tests: Testing the Validity of a KABC-II Adaptation in IndiaMalda, Maike; van de Vijver, Fons J. R.; Srinivasan, Krishnamachari; Transler, Catherine; Sukumar, Prathima

The authors evaluated the adequacy of an extensive adaptation of the American Kaufman Assessment Battery for Children, second edition (KABC-II), for 6- to 10-year-old Kannada-speaking children of low socioeconomic status in Bangalore, South India. The adapted KABC-II was administered to 598 children. Subtests showed high reliabilities, the Cattell—Horn—Carroll model underlying the original KABC-II was largely replicated, and external relations with demographic characteristics and an achievement measure were consistent with expectations. The subtests showed relatively high loadings on the general cognitive factor, presumably because of the high task novelty and, hence, cognitive complexity of the tests for the children. The findings support the suitability and validity of the KABC-II adaptation. The authors emphasize that test adaptations can only be adequate if they meet both judgmental (qualitative) and statistical (quantitative) adaptation criteria.
The Measurement of Dispositions to Rash Action in ChildrenZapolski, Tamika C. B.; Stairs, Agnes M.; Settles, Regan Fried; Combs, Jessica L.; Smith, Gregory T.

Among adolescents and adults, there appear to be at least four different personality traits that dispose individuals to rash or ill-advised action: sensation seeking, negative urgency, lack of planning, and lack of perseverance. The four are only moderately correlated and they appear to play different roles in dysfunction. It is important to determine whether the traits are present among preadolescents because of their possible influence on subsequent development. The authors developed assessments of the four traits for preadolescent children and found evidence supporting (a) the internal consistency of each trait measure, (b) the convergent and discriminant validity of the four measures using the multitrait, multimethod technique, and (c) the hypothesis that the different traits correlated with different dysfunctional behaviors as predicted by theory. Pending further validation efforts, it appears to be the case that researchers may be able to distinguish among different dispositions to rash action prior to adolescence.
