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.     

Personality and attitudinal correlates of healthy and unhealthy lifestyles in young adults

Abstract

The relationship between healthy lifestyle and personality and attitudinal variables was analyzed with data collected from 809 men and 996 women aged 18–30 years in England, Belgium, Finland and Norway as part of the European Health and Behaviour Survey. A health practices index was constructed on the basis of performance of sixteen behaviours including smoking, alcohol consumption, exercise, sleep time and a variety of dietary and preventive practices. Scores on the health practices index were higher in women than men, but in both sexes the index was normally distributed. Consistently healthy practices were positively correlated with extraversion and optimism, and negatively associated with neuroticism, psychoticism and chance locus of control beliefs. These effects were maintained after controlling for social desirability, but together accounted for only a modest proportion of the variance in the health practices index. The results are discussed in relation to the factors characterising health conscious and unhealthy lifestyles.     

Type D personality predicts poor medication adherence in myocardial infarction patients

Type D personality, the combination of negative affectivity (NA) and social inhibition (SI), is an emerging risk factor in cardiovascular disease. This study aimed to examine one possible behavioural mechanism to explain the link between Type D and ill-health. It was hypothesised that Type D personality would predict medication adherence in myocardial infarction (MI) patients. In a prospective study, 192 MI patients (54 females and 138 males) completed measures of Type D personality and provided demographic and medical information 1 week post-MI, and then 131 patients went on to complete a self-report measure of medication adherence 3 months post-MI. It was found that Type D personality predicts adherence to medication, after controlling for demographic and clinical risk factors. Critically, the constituent components of Type D, NA and SI, interact to predict medication adherence, after controlling for the effects of each component separately. Poor adherence to medication may represent one mechanism to explain why Type D cardiac patients experience poor clinical outcome, in comparison to non-Type D patients. Interventions, which target the self-management of medication, may be useful in these high-risk patients.     

Maintaining a healthy diet: Effects of personality and self-reward versus self-punishment on commitment to and enactment of self-chosen and assigned goals

Abstract

A theory decomposing volition into four modes of central organization of executive control functions is outlined. These modes include (1) an autonomy-oriented mode (“self-regulation”) which is facilitated by challenging conditions and positive mood, (2) a self-suppressive mode oriented toward external-control (“self-control”) facilitated by negative mood and two modes associated with volitional inhibition (“state orientation”). Two experiments are reported that test predicted interactions between dispositional and situational factors in determining commitment to and actual enactment of self-chosen versus assigned activities directed at changing nutritional behavior. The results confirm the predicted disordinal interactions: The degree of commitment to and enactment of intended behavioral changes depends upon an interaction between personality (volitional styles), type of self-regulatory task (eat more healthy versus avoid unhealthy food), and instructional focus on easy versus difficult steps (Study 1) or self-reward versus self-punishment strategies (Study 2). Practical implications for designing intervention procedures according to individual personality characteristics and situational constraints are discussed.     

Ten years of career success in relation to individual and situational variables from the employee development literature

Individual, situational, and socio-demographic variables from the employee development literature were combined with theory and research on career success in a ten-year study of 289 workers from across many jobs and industries in the workforce. Support for employee development by one's employer ten years prior and a trend of increasing/accumulating support contributed to career success, providing the first long-term confirmation of the value to careers from support for development by employers. Proactive personality had unique effects on success not accounted for by a broad array of other variables, strengthening conclusions from prior research about the predictive value of proactive personality which were based on data not controlling for these variables. Finally, achievement goal orientation influenced success in a unique way via “profile effects:” Goal orientation dimensions interacted to predict success, suggesting simple linear effects (e.g. being more learning-oriented) may be inadequate in explaining career success. Implications for future research and practice are discussed.     

Exploring the Role of Spirituality in the Context of the Five Factor Model of Personality in a South African Sample

The study explored the relationship between the Five Factor Model of personality and spirituality by using the NEO PI-R (Costa & McCrae, 1992) and the Spiritual Transcendence Scale (STS) (Piedmont, 1999) respectively. Participants were 94 psychology undergraduate students at a large South African university (mean age = 19.1 years; SD =1.43, males =19, females=75). Data were analyzed using both correlations as well as principal components analysis with varimax rotation. Evidence from both correlations and factor analysis suggest separate domains within the FFM as well as a separate factor for spirituality. These results provide support for claims that aspects of spirituality are not accounted for by the FFM as operationalised by the NEO-PI-R and by implication the FFM may not be a complete taxonomy of personality.     

Students' Personality Traits and Learning Approaches

This study examined students' usage of deep and surface approaches to learning as well as the relationship between students' personality attributes and their approaches to learning. Participants were 284 undergraduate education students registered with a South African regular university (females = 195, males = 89). They completed the Revised two-factor Study Process Questionnaire (R-SPQ-2F) (Biggs, Kember, & Leung (2001) and Eysenck Personality Questionnaire (EPQ) (Eysenck & Eysenck, 1975, 1985). Data were analysed for differences in proportion endorsing learning approach type (deep, surface) and the association between learning approach and personality attributes. The students self-reported to use predominantly deep learning strategies and lower rather than high surface strategies. The personality attributes of Extraversion and Neuroticism were unrelated to self-reported primary learning strategy.     

The stalking of psychotherapists by current or former clients: Beware of the insecurely attached!

Abstract

A survey of psychological therapists who worked in primary care showed that the incidence of psychotherapists being harassed or stalked by their current or former clients was more than twice the national average at 24%. The stalkers fell into three broad categories: those clients who were needy and made early attachments to their therapists; those experiencing erotic transference; and those with personality disorders, especially those with a narcissistic style. All of these are disorders of attachment. This paper discusses the neurobiological development of an insecure attachment and how that manifests during therapy in stalking behaviour. Psychotherapists who are aware of the dynamics within the therapeutic relationship can take preventative steps to inhibit the automatic fear response of a client who is insecurely attached and which may lead to stalking behaviour.
