Personality Traits and Body Weight Measures: Concurrent and Across‐Time Associations

We tested the possibility that the five‐factor model of personality is associated with three measures of body weight and with changes in their levels over time and that these associations are gender specific. The study was conducted at two points of time, Time 1 (2664 participants) and Time 2 (1492 participants), over approximately 4 years, controlling for gender, age, education, and having a chronic disease. Body weight was assessed by body mass index, waist circumference, waist‐to‐hip ratio, and the five‐factor model by Saucier's Mini‐Markers. Cross‐sectional regression results indicated that conscientiousness was negatively associated with the three body weight measures, whereas neuroticism and extraversion were positively associated with the three body weight measures. The longitudinal regression results indicate that extraversion was associated with an increase in two of the body weight measures. Neuroticism was associated with increase in all three body weight measures and more strongly for women than for men. Openness was associated with a decrease in all three body weight measures for women, but this association was not significant for men. These findings help identify personality traits that lead to risk of weight gain and point to the modifying role of gender. Copyright © 2013 John Wiley & Sons, Ltd.     

Psychological Well-Being of Canadian Forces Officer Candidates: The Role of Personality and Coping Strategies

Previous research has suggested that personality influences the coping strategies an individual uses to deal with stressors, which, in turn, influences psychological well-being. This study examines whether coping strategies mediate the relationship between neuroticism and the psychological well-being of Canadian Forces officer candidates undergoing basic training. Only partial evidence was found for the mediating role of coping strategies between neuroticism and psychological well-being. These findings suggest that coping strategies and personality may constitute two independent constructs, both of which have significant contributions to well-being among military personnel.     

Mental Health Services Use Intentions Among Canadian Military Recruits

Identifying the factors associated with mental health services use (MHSU) is an important step in developing strategies to improve services access and delivery. The aims of the present study were to (a) identify personality and individual difference characteristics associated with MHSU intentions within the framework of the Theory of Planned Behavior (TPB) and (b) explore complex relationships that might exist between these characteristics and determinants of MHSU intentions identified in TPB, including attitudes, subjective norms, and perceived behavioral control. Data for 244 Canadian Armed Forces recruits who completed a MHSU questionnaire following mental health training were linked to personality data collected earlier. Multivariate analyses showed that the relationship between agreeableness and MHSU intentions was mediated by instrumental attitudes and subjective norms. The relationship between hardiness and MHSU intentions was mediated by subjective norms and self-efficacy. Findings suggest it may be worthwhile to consider mental health education initiatives to improve MHSU.     

Modeling Interactions Between Latent Variables in Research on Type D Personality: A Monte Carlo Simulation and Clinical Study of Depression and Anxiety

Several approaches exist to model interactions between latent variables. However, it is unclear how these perform when item scores are skewed and ordinal. Research on Type D personality serves as a good case study for that matter. In Study 1, we fitted a multivariate interaction model to predict depression and anxiety with Type D personality, operationalized as an interaction between its two subcomponents negative affectivity (NA) and social inhibition (SI). We constructed this interaction according to four approaches: (1) sum score product; (2) single product indicator; (3) matched product indicators; and (4) latent moderated structural equations (LMS). In Study 2, we compared these interaction models in a simulation study by assessing for each method the bias and precision of the estimated interaction effect under varying conditions. In Study 1, all methods showed a significant Type D effect on both depression and anxiety, although this effect diminished after including the NA and SI quadratic effects. Study 2 showed that the LMS approach performed best with respect to minimizing bias and maximizing power, even when item scores were ordinal and skewed. However, when latent traits were skewed LMS resulted in more false-positive conclusions, while the Matched PI approach adequately controlled the false-positive rate.     

Do as you’re told! Facets of agreeableness and early adult outcomes for inner-city boys

With data from the middle cohort of the Pittsburgh Youth Study, a prospective longitudinal study of inner-city boys, we examined whether Big Five agreeableness facets could be reliably recovered in this sample, and whether facets predicted educational, occupational, social, and antisocial life outcomes assessed a decade later. Caregivers described their adolescent boys’ personalities using the Common California Q-Set; twelve years later, participants were interviewed and court records were obtained. Factor analyses recovered two facets: compliance and compassion. Compliance predicted more schooling and lower risk of unemployment, teenage fatherhood, and crime; compassion related to longer committed relationships. Findings highlight the value of studying personality at the facet level.     

The general factor of personality and general intelligence: Evidence for substantial association

Despite theoretical assertions derived from life history theory, research on the relationship between the general factor of personality and general intelligence has shown that there is little overlap between the two higher-order constructs. It is argued that the association between these general factors is largely attenuated by measurement error in assessing the general factor of personality. A substantial association between the general factors at multiple points in time was found when the general factor of personality was derived from rater Q-sorts. The results have important implications for the study of individual differences.

Individual differences in susceptibility to infection and illness following respiratory virus challenge

Abstract

The aim of the present research was to investigate whether susceptibility to experimentally-induced respiratory virus infections and illness is related to measures of personality, physiological state, performance efficiency, and subjective ratings of alertness and motivation obtained prior to virus challenge. Two studies, using different viruses, showed that volunteers who subsequently developed colds had higher temperatures prior to virus challenge than those who remained free from illness. Similarly, those who later had colds were worse than other volunteers on certain performance tests given in the pre-challenge period. The results also showed that task-related motivation was related to subsequent infection. Personality scores were poor predictors of infection and illness, the only exception being introversion, which, in one study, was related to the likelihood of developing a sub-clinical infection.     

Personality predictors of smoking behavior in a sample of physicians

Abstract

The smoking status of 239 physicians was obtained from a mail survey in 1981. MMPI data, which had been obtained from these men 25 years earlier, was used to prospectively predict smoking status at follow-up. Those who never smoked had scores indicative of social conventionality (low scores on L, Pd, and Schubert scales; high scores on Ego-control). A similar pattern was found among smokers who quit after a relatively short smoking history. Compared to ex-smokers, those who continued to smoke at the time of follow-up were characterized by high scores on the Pd and Ma scales. These results were discussed in terms of a multi-stage conceptualization of the smoking cessation process.     

The distressed (Type D) personality mediates the relationship between remembered parenting and psychological distress in cardiac patients

Objective: Both the distressed (Type D) personality (i.e. the combination of negative affectivity and social inhibition traits) and dysfunctional parenting styles are associated with anxiety and depression. As parenting styles have been related to personality development, dysfunctional parenting styles may also be associated with Type D personality. We examined whether remembered parenting was associated with anxiety and depression in cardiac patients and whether Type D personality mediated this relationship.

Methods: Our sample comprised 435 patients treated with percutaneous coronary intervention (PCI) and 123 patients with congestive heart failure (CHF). Patients completed the Hospital Anxiety and Depression Scale, Type D Scale (DS14), and Remembered Relationship with Parents (RRP¹⁰) scale.

Results: Remembered parenting was significantly associated with higher anxiety and depression levels and Type D personality. In multivariable linear regression analyses, Type D personality accounted for 25–29% of the variance in anxiety and 23–46% of the variance in depression, while remembered parenting was no longer significantly associated with these domains. Sobel tests and bootstrapping indicated that Type D personality mediated the relationship between remembered parenting and anxiety and depression.

Conclusion: Type D personality mediated the relationship between remembered parenting and anxiety and depression in both PCI and CHF patients.
