Workaholism has become an increasingly popular area for empirical study. However, most studies examining the prevalence of workaholism have used non-representative samples and measures with poorly defined cut-off scores. To overcome these methodological limitations, a nationally representative survey among employees in Norway (N = 1,124) was conducted. Questions relating to gender, age, marital...

BACKGROUND Even though the Five Factor Model (FFM) has been the dominant paradigm in personality research for the past two decades, very few studies have measured the FFM adaptively. Thus, the purpose of this research was the building of a new item pool to develop a computerized adaptive test (CAT) for personality assessment. METHOD A pool of 480 items that measured the FFM facets was develop...

This article explicates the theory of drive and describes the development and validation of two measures. A representative set of drive facets was derived from an extensive corpus of human attributes (Study 1). Operationalised using an International Personality Item Pool version (the Drive:IPIP), a three-factor model was extracted from the facets in two samples and confirmed on a third sample (...

Cognitive failures at work (or errors in the workplace including blunders and memory lapses), can lead to considerable personal and organisational damage, even damage well beyond national borders in some organisations. Workplace errors may have a personality base; and mindfulness (or mindlessness) also appears to be related to workplace errors generally. Given the importance and cost of errors ...

OBJECTIVES A low number of natural teeth, indicating poor oral health, is associated with various adverse outcomes to the extent that it has been proposed as a screening marker of life quality in older age. To further understand the mechanisms underlying oral health, this study investigated the associations between the number of natural teeth and personality traits in older age. METHOD In 793...

Factor analyses of 75 facet scales from 2 major Big Five inventories, in the Eugene-Springfield community sample (N=481), produced a 2-factor solution for the 15 facets in each domain. These findings indicate the existence of 2 distinct (but correlated) aspects within each of the Big Five, representing an intermediate level of personality structure between facets and domains. The authors charac...

Researchers often use exploratory factor analysis (EFA) to develop and refine questionnaires assessing the Big Five personality traits. We use sequential sampling and bootstrapping to determine the number of participants needed to yield stable loading patterns for the Big Five Inventory (BFI) and the International Personality Item Pool Big Five measure (IPIP). Overall 21,350 participants (BFI =...

Objective: In fall 2006, the authors examined associations between the five-factor model of personality and several key health behaviors. Methods: College students (N = 583) completed the American College Health Association–National College Health Assessment and the International Personality Item Pool Big Five short-form questionnaire. Results: Highly conscientious individuals were more likely ...
