Statistically modelling the relationships between Type D personality and social support,health behaviors and symptom severity in chronic illness groups

Objective: The study aimed to develop a predictive model of how Type D personality influences health behaviours, social support and symptom severity and assess its generalisability to a range of chronic illnesses.

Design: Participants were classified as either healthy (n = 182) or having a chronic illness (n = 207). Participants completed an online survey measuring Type D and a range of health-related variables. Chronic illness participants were classified as having either a functional somatic syndrome (i.e. chronic fatigue syndrome or fibromyalgia), where the underlying pathological processes were unclear, or illnesses such as type 2 diabetes, osteoarthritis or rheumatoid arthritis, where the causes are well understood.

Main Outcome Measures: Outcome measures were health behaviours, social support and both physical and psychological symptoms.

Results: The rate of Type D was higher in chronic illness participants (53%) than in healthy controls (39%). Negative affectivity (NA) and social inhibition (SI) both correlated with outcome measures, although NA was generally the stronger predictor. Using NA and SI as independent subscales led to superior prediction of health outcomes than using categorical or continuous representations.

Conclusion: Findings suggest that the relationship between Type D and health outcomes may generalise across different chronic illnesses.     

Genetic Testing Considerations in Breast Cancer Patients

Genetic testing is now feasible for a growing number of cancers. Although the implications for unaffected relatives have been widely described, the impact of the tests on affected individuals are often not recognized. We present and discuss four cases that highlight some of the issues—for example, feelings of guilt and anxiety, intrafamilial conflict, and support needs—that may arise in testing affected individuals. We offer some suggestions to aid in the approach to such testing.     

Personality and Integrative Negotiations: A HEXACO Investigation of Actor,Partner, and Actor–Partner Interaction Effects on Objective and Subjective Outcomes

The present study sought to expand the literature on the relations of major dimensions of personality with integrative negotiation outcomes by introducing the HEXACO model, investigating both effects of the negotiators' and their counterparts' personality traits on objective and subjective negotiation outcomes, and investigating two interactions between the negotiators' and counterparts' personalities. One hundred forty‐eight participants completed the HEXACO‐100 measure of personality. Participants then engaged in a dyadic negotiation task that contained a mix of distributive and integrative elements (74 dyads). Measures of subjective experience and objective economic value were obtained, and actor–partner interdependence models were estimated. Personality was generally a better predictor of subjective experience than objective economic value. In particular, partner honesty‐humility, extraversion, and openness predicted more positive negotiation experiences. An actor–partner interaction effect was found for actor‐agreeableness by partner‐honesty‐humility on economic outcomes; agreeable actors achieved worse (better) economic outcomes when negotiating with partners that were low (high) on honesty‐humility. © 2018 European Association of Personality Psychology     

Effectively Coping With Task Stress: A Study of the Validity of the Trait Emotional Intelligence Questionnaire–Short Form (TEIQue–SF)

In this study, we investigated the validity of the Trait Emotional Intelligence Questionnaire–Short Form (TEIQue–SF; Petrides, 2009) in the context of task-induced stress. We used a total sample of 225 volunteers to investigate (a) the incremental validity of the TEIQue–SF over other predictors of coping with task-induced stress, and (b) the construct validity of the TEIQue–SF by examining the mechanisms via which scores from the TEIQue–SF predict coping outcomes. Results demonstrated that the TEIQue–SF possessed incremental validity over the Big Five personality traits in the prediction of emotion-focused coping. Results also provided support for the construct validity of the TEIQue–SF by demonstrating that this measure predicted adaptive coping via emotion-focused channels. Specifically, results showed that, following a task stressor, the TEIQue–SF predicted low negative affect and high task performance via high levels of emotion-focused coping. Consistent with the purported theoretical nature of the trait emotional intelligence (EI) construct, trait EI as assessed by the TEIQue–SF primarily enhances affect and performance in stressful situations by regulating negative emotions.     

Using text analysis software to detect deception in written short‐answer questions in employee selection

This study investigated if word frequencies informed by the Newman‐Pennebaker (NP) and Reality Monitoring (RM) models could classify honest and deceptive responses to short‐answer questions often used in online employee applications. Participants (n = 106; 58% male; M_age = 30.28 years, SD = 8.85) completed two written short‐answer questions both deceptively and honestly. The questions asked participants to describe a notable personal achievement or a time where they had demonstrated interpersonal skills. Linguistic Inquiry and Word Count was used to calculate the prevalence of words in various linguistic categories. Deceptive statements contained significantly fewer first‐person singular pronouns, auxiliary verbs, adverbs, conjunctions, and cognitive process words. Results revealed the NP and RM models accuracy at classifying responses varied on question type.     

Comparing Job Applicants to Non‐applicants Using an Item‐level Bifactor Model on the HEXACO Personality Inventory

The present study evaluated the ability of item‐level bifactor models (a) to provide an alternative explanation to current theories of higher order factors of personality and (b) to explain socially desirable responding in both job applicant and non‐applicant contexts. Participants (46% male; mean age = 42 years, SD = 11) completed the 200‐item HEXACO Personality Inventory‐Revised either as part of a job application (n = 1613) or as part of low‐stakes research (n = 1613). A comprehensive set of invariance tests were performed. Applicants scored higher than non‐applicants on honesty‐humility (d = 0.86), extraversion (d = 0.73), agreeableness (d = 1.06), and conscientiousness (d = 0.77). The bifactor model provided improved model fit relative to a standard correlated factor model, and loadings on the evaluative factor of the bifactor model were highly correlated with other indicators of item social desirability. The bifactor model explained approximately two‐thirds of the differences between applicants and non‐applicants. Results suggest that rather than being a higher order construct, the general factor of personality may be caused by an item‐level evaluative process. Results highlight the importance of modelling data at the item‐level. Implications for conceptualizing social desirability, higher order structures in personality, test development, and job applicant faking are discussed.
