The purpose of this paper is to examine the convergent and nomological validity of a GPS-based measure of daily activity, operationalized as Number of Places Visited (NPV). Relations among the GPS-based measure and two self-report measures of NPV, as well as relations among NPV and two factors made up of self-reported individual differences were examined. The first factor was composed of variab...

pemphigus is a rare autoimmune blistering disease with different phenotypes. the evaluation of therapeutic interventions requires a reliable, valid and feasible to use measurement. however, there is no gold standard to measure the disease activity in clinical trials. in this study we aimed to introduce the pemphigus vulgaris activity score (pvas) measurement and to assess the convergent validit...

BACKGROUND AND OBJECTIVES The Faces Pain Scale-Revised (FPS-R) and Color Analog Scale (CAS) are self-report pain scales commonly used in children but insufficiently validated in the emergency department setting. Our objectives were to determine the psychometric properties (convergent validity, discriminative validity, responsivity, and reliability) of the FPS-R and CAS, and to determine whether...

Confirmatory factor analysis was used to model a multitrait (attention deficit hyperactivity disorder [ADHD]-inattention, ADHD-hyperactivity/impulsivity, oppositional defiant disorder [ODD]) by multisource (mothers, fathers, and teachers) matrix to determine the convergent and discriminant validity of ratings by mothers, fathers, and teachers. Participants were 1,749 elementary school children ...

BACKGROUND Negative symptoms are considered core symptoms of schizophrenia. The Brief Negative Symptom Scale (BNSS) was developed to measure this symptomatic dimension according to a current consensus definition. The present study examined the psychometric properties of the German version of the BNSS. To expand former findings on convergent validity, we employed the Temporal Experience Pleasure...

The main aim of this study was to establish the convergent and discriminant validity of a single-item measure of daily fatigue ("How fatigued do you currently feel?") in a daily diary context. Convergent validity of our measure was examined by relating it to a validated multiple-item measure of fatigue (Profile of Mood States; McNair, Lorr, & Droppelman, 1971) and to other daily (work-home inte...
