Background. Different individuals have alpha waves with different wavelengths. The distribution of the wavelengths is assumed to be bell-shaped and smooth. Although this view is generally accepted, it is still just an assumption and has never been critically tested. When exploring the relationship between alpha waves and personality traits, it makes a huge difference if the distribution of the ...

Article history: Keywords: Measurement equivalence Latent means Personality Paper-and-pencil test Computer-based test Proctoring a b s t r a c t Despite substantial interest and research in measuring personality, little is known about the measurement equivalence and mean differences in scores on personality measures across different administration conditions. The aim of the present study was to...

Introduction: The original 89-item Zuckerman-Kuhlman Personality Questionnaire (form III Revised, ZKPQ-III-R) is a widely accepted and used self-report measure for personality traits. This study assessed the reliability and construct validity of the Chinese short 46-item version of the ZKPQ-III-R in a sample of adolescents and young adults. Methodology: A total of 1,019 Chinese adolescents and ...

This study describes the relation between personality items' validities, defined as the items' correlations with acquaintance ratings on the Big 5 personality factors, and other itemmetric properties including ambiguity, syntactic complexity, social desirability, content, and trait indicativity. Five external validity coefficients for each item on the California Psychological Inventory were cor...

Introduction ‘Dark Triad’ is a constellation of three conceptually distinct but empirically overlapping personality variables. The members- Machiavellianism, narcissism and subclinical psychopathy – often show differential correlates share common core callous-manipulation. Objectives To validate an easy to use valid measurement for populations examining the 3 factors dark triad personality. Met...

The Dynamic Analog Scale (DAS) is introduced as a technique for generating single-item measures of personality traits. The DAS is comprised of extensive trait definitions and an analog scale on which respondents simultaneously rate themselves and others. In two studies the Big Five personality traits were assessed with the DAS and compared to a multiple-item questionnaire that measured the same...

PreVisor The current study proposes and illustrates a method for examining item complexity during test construction using item response theory. We examined whether differential item functioning existed within 4 personality scales across cognitive ability groups. Results indicated that personality items do differentially function across highly disparate cognitive ability groups. Organizations ar...

BACKGROUND To develop and validate an item bank to measure mobility in older people in primary care and to analyse differential item functioning (DIF) and differential bundle functioning (DBF) by sex. METHODS A pool of 48 mobility items was administered by interview to 593 older people attending primary health care practices. The pool contained four domains based on the International Classifi...

Researchers have proposed replacing the current system for diagnosing personality disorders with a dimensional trait model. Proposed trait models have been derived primarily from data provided by untrained lay informants (often via self-report questionnaires) using item sets derived from lay conceptions of personality. An alternative is to derive personality trait dimensions from data provided ...

Prior research has yielded mixed results regarding what contributes to psychometrically sound multiple-choice (MC) items. The purpose of the present study was, therefore, twofold: (a) to compare 3-, 4-, and 5-option multiple-choice (MC) tests in terms of psychometric characteristics, and (b) to investigate the relationships between three MC tests and five personality traits. To that end, 150 st...
