BACKGROUND Diverse national and international organizations have been developing projects for many years to improve testing practices. The main goal of this paper is to present the revised model of the European Federation of Psychologists' Associations (EFPA) for the evaluation of the quality of tests. This model aims to provide test users with rigorous information about the theoretical, practi...

OBJECTIVE To conceptualize, develop, and provide preliminary psychometric evidence for the Adherence Estimator--a brief, three-item proximal screener for the likelihood of non-adherence to prescription medications (medication non-fulfillment and non-persistence) for chronic disease. RESEARCH DESIGN AND METHODS Qualitative focus groups with 140 healthcare consumers and two internet-based surve...

BACKGROUND & AIMS It remains unknown what the prevalence of minimal hepatic encephalopathy is in Taiwan, a highly endemic country for chronic viral hepatitis infection. It is also unclear whether abnormal serum cytokine levels can be indicative of the presence of minimal hepatic encephalopathy. We aimed to standardize the tests of psychometric hepatic encephalopathy score and predictive value o...

There is a long history of calls for combining cognitive science and psychometrics (Cronbach, 1975; Snow & Lohman, 1989). The U.S. standards movement, begun more than 20 years ago (McKnight et al., 1987; National Council of Teachers of Mathematics, 1989), sought to articulate public standards for learning that would define and promote successful performance by all students; establish a common b...

OBJECTIVE To develop and validate the Adult Hypopituitarism Questionnaire (AHQ) as a disease-specific, self-administered questionnaire for evaluation of quality of life (QOL) in adult patients with hypopituitarism. METHODS We developed and validated this new questionnaire, using a standardized procedure which included item development, pilot-testing and psychometric validation. Of the patient...

BACKGROUND AND AIM Helicobacter pylori (H. pylori) bacteria convert urea to ammonia, which has been implicated in causation of hepatic encephalopathy in patients with liver cirrhosis. The role of H. pylori infection in causation of minimal hepatic encephalopathy (MHE) has not been well studied. We looked at the relationship of H. pylori infection with MHE and hyperammonemia in patients with liv...

BACKGROUND Cerebral vision disorders (CVDs) are frequent after brain damage and impair the patient's outcome. Yet clinically and psychometrically validated procedures for the anamnesis of CVD are lacking. OBJECTIVE To evaluate the clinical validity and psychometric qualities of the Cerebral Vision Screening Questionnaire (CVSQ) for the anamnesis of CVD in individuals poststroke. METHODS Ana...
