Association between blood lipid levels and personality traits in young Korean women.

Abstract: Abnormal lipid levels are important etiological factors associated with the development of atherosclerosis and with increased cardiovascular morbidity and mortality. Lipid levels are also influenced by lifestyle and behavioral factors, which suggests that personality traits might be related to abnormal lipid profiles. Studies on personality traits and lipid levels are relatively scarce in Korea. Therefore, the objective of this study was to examine the association between lipid levels and personality traits in young Korean women. A total of 1,701 young Korean women [mean age = 24.9±4.6 years (range 17-39)] who volunteered for personality trait evaluation were recruited for this study. Lipid levels, including total cholesterol, high density lipoprotein (HDL) cholesterol, and triglyceride, were measured in all subjects after an overnight fast, and a low density lipoprotein (LDL) cholesterol level was calculated. The study population was divided into abnormal and normal lipid level groups according to the clinical criteria. Personality traits were measured using the Revised NEO Personality Inventory for the Five-Factor Model of personality. High neuroticism was associated with low HDL cholesterol levels. Low extraversion and openness were associated with high levels of triglyceride. At the facet level, the association between personality and lipid levels were generally consistent. Angry hostility, self-consciousness, vulnerability to stress, activity, and straightforwardness were associated with HDL cholesterol levels. Activity, positive emotion, aesthetics, actions, and deliberation were associated with triglyceride. When applying clinical criteria, conscientiousness was less likely to have abnormal total cholesterol levels. Our results showed that the women with the low HDL cholesterol levels are like to be more neurotic and the hyperglycemic women are prone to lower extraversion and openness in Korea. Understanding the associations between blood lipid levels and personality traits may have a beneficial effect for the managing of dyslipidemia.

Validation of the Basque Revised NEO Personality Inventory (NEO PI-R)

Abstract: Although personnel selection processes for Basque civil servants often involve the assessment of personality, there are currently no Basque self-report instruments that provide valid and reliable measures of the Big-Five factors of personality. The aim of this study was to validate the Basque version of the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae, 1992), by examining its psychometric properties. We assessed the dimensionality of the instrument, the convergent and discriminant validity, the temporal stability, and the internal consistency of each dimension. Relationships between NEO PI-R domains and other variables (i.e., gender and age) were also examined. The sample was composed of 1,790 participants (1,031 women and 759 men), whose ages ranged between 16 and 65. Results suggest that the Basque version of NEO PI-R allows assessing personality from the Big-Five framework in a valid and accurate way. The age and gender pattern of personality domains are in consonance with previous findi...

Cross-cultural personality assessment: The Revised NEO Personality Inventory in China

Abstract: The Mandarin Chinese version of Costa and McCrae’s (1992) Revised NEO Personality Inventory (NEO-PI-R) was used to survey 473 people from 9 occupational groups in mainland China. Internal consistency was adequate for almost all dimensions. Correlations with occupation and gender sustained the validity of NEO-PI-R. The differences of mean value between Chinese participants and an American sample (Costa & McCrae, 1992) were significant in 4 dimensions. However, further validation of the 5-factor model for the assessment of personality in China is needed.

Personality assessment in a diverse urban sample.

Abstract: Personality traits – our characteristic ways of thinking, feeling, and behaving – have been implicated in disease progression and health outcomes In particular, the traits that define the Five-Factor Model (FFM) of personality, Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness, are associated with inflammation (Chapman et al, 2009; Sutin et al, 2010), obesity (Sutin, Ferrucci, Zonderman, & Terracciano, 2011), cardiovascular disease (Strike & Steptoe, 2004), and, ultimately, longevity (Kern & Friedman, 2008; Terracciano, Lockenhoff, Zonderman, Ferrucci, & Costa, 2008) The pervasiveness of these traits and their relevance to health outcomes make them a promising avenue for examining the role of psychological factors in health in vulnerable populations Some traits, for example, may ameliorate health disparities, whereas others may exacerbate them To address questions about the role of personality in health outcomes across different demographic groups, it is imperative to have a measurement tool that assesses these traits reliably in the populations of interest Personality measures have typically been constructed and validated using college students or other educated adults (Costa & McCrae, 1992; John & Srivastava, 1999) Less research has addressed the psychometric properties of established personality measures in ethnically and socioeconomically diverse populations, especially among those with low levels of literacy The Revised NEO Personality Inventory (NEO-PI-R) is a well-replicated measure of FFM personality traits (Costa & McCrae, 1992) Cross-cultural evidence suggests that the NEO-PI-R reliably assesses personality traits across different populations and that nations as diverse as Burkina Faso and Iceland share a similar factor structure to the normative American structure (McCrae et al, 2005) These studies, however, despite their diversity of culture, typically rely on college students at respondents Thus, despite providing knowledge about the universal structure of personality, they do not address personality assessment in populations that vary greatly in literacy Data quality and the factor structure of the NEO-PI-R tend to be similar across sex and age (Costa & McCrae, 1992) but may vary across other demographic groups African American samples, for example, tend to have a higher percentage of NEO-PI-R assessments judged invalid and higher acquiescence (ie, the tendency to agree with items regardless of their content; Savla, Davey, Costa, & Whitfield, 2007) Invalidity and acquiescence, however, may be more strongly related to education than to ethnicity (Lockenhoff et al, 2008) Internal consistency of the five personality factors tend to be slightly lower among African Americans (Savla et al, 2007) and in populations with lower levels of education, regardless of ethnicity (Lockenhoff et al, 2008) Finally, congruence with the normative factor structure tends to be fairly high, but African American samples have slightly lower congruence coefficients for Extraversion and Openness to Experience, suggesting that perhaps the items in these domains do not measure these traits as well for African Americans as for White participants (Salva et al, 2007) Less research has addressed the issue of literacy in personality assessment The factor structure of the NEO-PI-R has been clearly replicated in samples with lower levels of education (Allik & McCrae, 2004; Trobst et al, 2000) Although related, literacy and education are not equivalent, and in some domains literacy may be more important than education in predicting outcomes of interest (eg, cognitive performance; Byrd, Jacobs, Hilton, Stern, & Manly, 2005) Personality assessment relies heavily on the respondent’s ability to comprehend and respond to the meaning of the items Data quality and factor structure may thus be compromised for individuals with lower levels of literacy who may have difficulty understanding questions about their personality The present research examines the data quality and factor structure of personality traits measured with the NEO-PI-R in a socioeconomically diverse urban sample In addition to the total sample, we test data quality in a number of demographic groups – African American and White participants above and below 125% of the federal poverty line – and in those with higher and lower literacy We evaluated the assessment on several dimensions, including percentage of invalid NEO-PI-Rs, acquiescence, internal consistency, and factor congruence with the normative sample We also performed a readability analysis on the items of the NEO by factor to determine reading level of each factor We expected these indices to be somewhat lower in those with lower SES and lower literacy

Neuroticism but not omega-3 fatty acid levels correlate with early responsiveness to escitalopram

Abstract: BACKGROUND Omega-3 fatty acid (O3FA) levels and dimensional personality measures have been associated with major depression and the course of depressive illness. We sought to study the utility of O3FA levels and dimensional personality measures as predictors of early improvement with escitalopram. METHODS Twenty-four participants were enrolled in an open-label trial of escitalopram 10 mg/d for 4 weeks. Baseline erythrocyte O3 levels and dimensional personality assessments were obtained. RESULTS Using a conservative, intention-to-treat analysis, baseline neuroticism (r = -0.57; P = .007), as measured by the Revised NEO Personality Inventory but not erythrocyte O3 levels, was correlated with improvements on escitalopram. A facet analysis of the neuroticism domain showed the relationship with antidepressant response to be focused on trait anxiety (r = -0.65; P = .002). CONCLUSIONS Anxiety may have important prognostic implications on subsequent response to selective serotonin reuptake inhibitors, such as escitalopram.
