The Barratt Impulsivity Scale (BIS), a 30-item self-report measure, is one of the most commonly used scales for the assessment of the personality construct of impulsiveness. It has recently marked 50 years of use in research and clinical settings. The current BIS-11 is held to measure 3 theoretical subtraits, namely, attentional, motor, and non-planning(More)
The psychological literature currently emphasizes reporting the "effect size" of research findings in addition to the outcome of any tests of significance. However, some confusion may result from the fact that there are three distinct uses of effect sizes in the psychological literature, namely, power analysis, research synthesis, and research reporting.(More)
Increases in the availability of gambling heighten the need for a short screening measure of problem gambling. The Problem Gambling Severity Index (PGSI) is a brief measure that allows for the assessment of characteristics of gambling behavior and severity and its consequences. The authors evaluate the psychometric properties of the PGSI using item response(More)
Although a growing body of empirical literature provides some support for the diagnosis of borderline personality disorder (BPD) in youth, little is known about the internal structure of BPD and the performance of the individual diagnostic criteria, especially in younger samples. We used item response theory (IRT) methods to investigate the psychometric(More)
Despite historical concerns about the validity of the construct of borderline personality disorder (BPD) in adolescence, there is now general consensus that BPD in adolescence constitutes a valid and reliable diagnosis. Yet the development and refinement of measures to assess borderline traits in adolescents is in its infancy. Moreover, brief and(More)
This research examines the role of friendship contingent self-esteem (FCSE), or self-esteem that is dependent on the quality of one's friendships, in predicting depressive symptoms. In Study 1, the authors developed a measure of FCSE. Both FCSE and others' approval correlated with self-esteem and depressive symptoms, but when entered simultaneously in a(More)
Gender differences in prevalence rates of Borderline Personality Disorder (BPD) may reflect true differences between groups or may reflect some form of gender bias in diagnostic criteria. The detection of differential item functioning (DIF) using item response theory methods provides a powerful method of evaluating whether gender differences in prevalence(More)
We previously examined provider׳s understanding of the 2013 American College of Cardiology/American Heart Association (ACC/AHA) cholesterol management guideline (DOI: http://dx.doi.org/10.1016/j.jacl.2015.11.002)(Virani et al., 2013) [1], and also assessed whether a case-based educational intervention could improve providers׳ knowledge gaps and attitudes(More)
(1986) argued that a theory-testing research orientation contributes to a confirmation bias that impedes the progress of research. To eliminate this confirmation bias, they proposed two complementary result-centered approaches: the method of condition seeking and the design approach. We argue that Greenwald et al. confused the relation between theory and(More)
