Article: Formal assessment of voluntariness with a three-part consent process.
[show abstract] [hide abstract]
ABSTRACT: Informed consent that is voluntary and made by an individual who is knowledgeable and competent is a foundational requirement for protecting human subjects from harm and exploitation that could result from research participation. In 1974 Miller and Willner proposed a two-part consent process that involved disclosure of information and assessment of comprehension. The authors propose a brief third component to the consent process: assessment of voluntariness. Three steps are involved: generate a list of potential coercive influences on the basis of the research population and the study context, develop a set of questions to assess the presence and intensity of the impact of these influences, and identify alternative courses of action should coercion be identified.Psychiatric services (Washington, D.C.) 01/2011; 62(1):87-9. · 2.81 Impact Factor -
Article: The Self-Report Psychopathy Scale and passive avoidance learning: a validation study of race and gender effects.
[show abstract] [hide abstract]
ABSTRACT: The reliability and validity of the Self-Report Psychopathy Scale (SRPS) was examined in a noninstitutionalized offender sample of mixed gender and race. Adequate alpha coefficients were obtained for the total sample and across gender and race. The SRPS was compared to measures of trait anxiety and passive avoidance errors. SRPS total, primary, and secondary scores were positively and significantly correlated with trait anxiety and passive avoidance (commission) errors, but not omission errors. Employing hierarchical regression models, no anxiety, gender, or ethnic effects were found. Intelligence confounded the relationship between psychopathic traits and passive avoidance errors. Findings provide tentative support of the SRPS as a valid measure of psychopathy.Assessment 07/2006; 13(2):197-207. · 2.01 Impact Factor -

Article: Interparental Agreement on Internalizing, Externalizing, and Total Behavior Problems: A Meta‐analysis
[show abstract] [hide abstract]
ABSTRACT: Previous studies have addressed the degree of correspondence between interparental reports of children's behavior problems, but have not examined the discrepancies in these reports. A meta-analysis containing 60 studies and 126 independent effect sizes was conducted. Results suggest that maternal and paternal ratings exhibit moderate correspondence in ratings of internalizing behavior problems in children and large correspondence in ratings of externalizing and total behavior problems in children. In terms of discrepancy of reports, parents reported similar levels of all types of problems. Age, gender, and socioeconomic status were found to moderate correspondence between mothers’ and fathers’ ratings but did not moderate discrepancies in mothers’ and fathers’ ratings.Clinical Psychology Science and Practice 11/2000; 7(4):435 - 453. · 2.92 Impact Factor -
Article: Using the PCL-R to help estimate the validity of two self-report measures of psychopathy with offenders.
[show abstract] [hide abstract]
ABSTRACT: Two self-report measures of psychopathy, Levenson's Primary and Secondary Psychopathy scales (LPSP) and the Psychopathic Personality Inventory (PPI), were administered to a large sample of 1,603 offenders. The most widely researched measure of criminal psychopathy, the Hare Psychopathy Checklist-Revised (PCL-R), served as a provisional referent for estimating the construct validity of these self-report measures with offenders. Compared with the LPSP, the PPI displayed higher zero-order correlations with the PCL-R, better convergent and discriminant validity, and more consistent incremental utility in predicting PCL-R scores. Furthermore, using a variant of Westen and Rosenthal's approach to evaluating the construct validity of a new measure, compared with the LPSP, the PPI's pattern of associations with measures of 35 external criterion variables was more similar to the pattern observed for the PCL-R. Results generally provide stronger support for the validity of the PPI than the LPSP in offender populations using the PCL-R as a provisional benchmark, particularly for assessing interpersonal and affective features of psychopathy.Assessment 11/2009; 17(2):206-19. · 2.01 Impact Factor
