INTRODUCTION Structural alterations may correlate with symptom severity in psychotic disorders, but the existing literature on this issue is heterogeneous. In addition, it is not known how cortical thickness and cortical surface area correlate with symptom dimensions of psychosis. METHODS Subjects included 455 individuals with schizophrenia, schizoaffective, or bipolar I disorders. Data were ...

The Engagement With Beauty Scale (EBS), designed from the aesthetics of I. Kant (1790/1987), G. W. F. Hegel (ca. 1835/1993), and T. Aquinas (ca. 1260/1947) and the psychological work of J. Haidt (J. Haidt & D. Keltner, 2004), measures engagement with natural, artistic, and moral beauty. In Studies 1 and 2, the authors describe scale construction, exploratory factor analysis, confirmatory factor...

The purpose of this study was to validate Japanese research version of Maslach Burnout Inventory-General Survey (MBI-GS), a newly developed measure intended for persons of every occupation. The Japanese MBI-GS was administered to a sample of hospital workers. Exploratory factor analysis found three factors, as in original MBI-GS. Confirmatory factor analysis largely supported MBI-GS structure o...

The psychometric properties of the short form of the Scale of Egalitarian Sex Role Attitudes (SESRA-S) were studied among human service professionals. An exploratory factor analysis yielded two factors interpreted as reflecting women's rights (e.g. women at home and men at work [a reverse item]) and women's independence (e.g. working outside is equally important for women [a non-reverse item]),...

In this study, the authors examined the reliability, structural validity, and concurrent validity of Zimbardo Time Perspective Inventory (ZTPI) scores in a group of 815 academically talented adolescents. Reliability estimates of the purported factors’ scores were in the low to moderate range. Exploratory factor analysis supported a five-factor structure similar to the one proposed by Zimbardo a...
