Four new neo-clerodane diterpenoids, scutebarbatines W-Z (1-4), were isolated from the ethanol extract of Scutellaria barbata (Labiatae), and their structures were elucidated on the basis of extensive spectroscopic studies. In addition, the proposed structures of at least seven 13-spiro subtype neo-clerodanes: scutehenanine B (5), scutebarbatine G (6), 6-O-nicotinoylscutebarbatine G (7), barbat...

Previous item factor analyses and readability analyses suggested that 14 of the 60 items in the NEO FiveFactor Inventory might usefully be replaced. New analyses in high school (N=1959) and adult (N=1492) samples led to the selection of new items from the remaining pool of Revised NEO Personality Inventory items. The resulting scales showed modest improvements in reliability and factor structur...

Interest in the role of personality traits in predicting academic performance outcomes has steadily increased over the last several decades, enough to produce a number of meta-analyses that summarize this research (e.g., Poropat, 2009; Richardson, Abraham, & Bond, 2012). These previous meta-analyses combine a variety of alternative personality measures under the assumption that they all reflect...

This study examined the effect of a selection context on the responses to a five factor personality questionnaire (Revised NEO Personality Inventory) of 974 candidates taking the entrance examination to the ENAC (National School of Civil Aviation, France). A response distortion index was calculated using Schinka, Kinder and Kremer (1997)’s method. The results indicate: 1) lower neuroticism scor...

This study presents new analyses of NEO Personality Inventory-Revised (NEO-PI-R) responses collected from a large British sample in a high-stakes setting. The authors show the appropriateness of the five-factor model underpinning these responses in a variety of new ways. Using the recently developed exploratory structural equation modeling (ESEM) technique, the authors show that model fits impr...

OBJECTIVE ADHD has been linked to various constructs, yet there is a lack of focus on how its symptom clusters differentially associate with personality, which this study addresses. METHOD The current study examines the relationship between impulsive and inattentive ADHD traits and personality, indexed by the Revised NEO Personality Inventory (NEO-PI-R) and the Millon Clinical Multiaxial Inve...

Personality traits are organized hierarchically, with narrow, specific traits combining to define broad, global factors. The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992c) assesses personality at both levels, with six specific facet scales in each of five broad domains. This article describes conceptual issues in specifying facets of a domain and reports evidence on the val...

This article recommends an alternative method for testing multifaceted constructs. Researchers often have to choose between two problematic approaches for analyzing multifaceted constructs: the total score approach and the individual score approach. Both approaches can result in conceptual ambiguity. The proposed bifactor model assesses simultaneously the general construct shared by the facets ...

The aim of this study was to analyse the psychometric properties of the Spanish NEO Five Factor Inventory-Revised (NEO-FFI-R) using Rasch analyses, in order to test its rating scale functioning, the reliability of scores, internal structure, and differential item functioning (DIF) by gender in a psychiatric sample. The NEO-FFI-R responses of 433 Spanish adults (154 males) with an anxiety disord...

The NEO Personality Inventory-Revised (NEO PI-R) measures normal personality characteristics and has demonstrated appropriate score reliability and validity. It is normed for two groups of individuals, college-age individuals 17 to 20 years old and adults 21 and older. Often, personality instruments normed on older individuals have been used with adolescent populations. To examine the appropria...
