TLDR
The findings suggest that the association between Type D personality and minor health complaints in the general population can be explained by feelings of stress and anxiety, but a precise biological mechanism for this link is yet to be elucidated.Abstract:
Type D personality has been associated with minor health complaints in the general population and dysregulation of basal cortisol secretion in coronary patients. The aims of the present study were to investigate (i) whether there is an association between Type D personality and basal cortisol secretion in the general population, and (ii) whether subjective measures of stress and anxiety, as well as indices of basal cortisol secretion, mediate the relationship between Type D personality and self-reported physical symptoms in this group. Self-report measures of stress, trait anxiety and physical symptoms were provided by 101 individuals aged 18–45 years. Saliva samples were also provided over two consecutive “typical” days, to enable indices of the cortisol awakening response and diurnal cortisol profile to be determined. There was a significant relationship between Type D personality and self-reported physical symptoms, which was fully mediated by subjective stress and anxiety. However, there were ...read more

Type D personality, stress, and symptoms of burnout: The influence of avoidance coping and social support
TL;DR: The authors investigated whether approach coping, avoidance coping, or perceptions of available social support mediated the relationship between Type D personality and perceived stress, and examined whether Type D moderated the relationship of perceived stress and symptoms of burnout.

TL;DR: Results indicate that dysregulated HPA axis activity is associated with suicidal ideation and behavior, and childhood trauma appears to be an important distal factor associated with HPA-axis dysregulation.

Genome-wide interaction study of a proxy for stress-sensitivity and its prediction of major depressive disorder
TL;DR: This study sought to generate a proxy for stress-sensitivity through modelling the interaction between SNP allele and MDD status on neuroticism score in order to identify genetic variants that contribute to the higher neuroticism seen in individuals with a lifetime diagnosis of depression compared to unaffected individuals.

A one-year prospective investigation of Type D personality and self-reported physical health
TL;DR: Although the relationships appear to be primarily driven by NA, the theory of a stress-related mechanism potentially underpinning the Type D-health relationship is supported and contributes to the literature continuing to highlight Type D personality as a risk factor for negative health outcomes.

Association between Satisfaction with Life and Personality Types A and D in Young Women with Acne Vulgaris.
TL;DR: In this paper, the authors examined the moderating and mediating role of personality type in the relationship between acne severity and satisfaction with life and found that people with acne vulgaris report a lower level of satisfaction with their life and are more frequently classified as having Type D personalities than those without acne.

TL;DR: In this paper, the authors present a discussion of whether, if, how, and when a moderate mediator can be used to moderate another variable's effect in a conditional process analysis.
Manual for the State-Trait Anxiety Inventory
TL;DR: The STAI as mentioned in this paper is an indicator of two types of anxiety, the state and trait anxiety, and measure the severity of the overall anxiety level, which is appropriate for those who have at least a sixth grade reading level.

A global measure of perceived stress.
TL;DR: The Perceived Stress Scale showed adequate reliability and, as predicted, was correlated with life-event scores, depressive and physical symptomatology, utilization of health services, social anxiety, and smoking-reduction maintenance and was a better predictor of the outcome in question than were life- event scores.

TL;DR: The long-term effect of the physiologic response to stress is reviewed, which I refer to as allostatic load, which is the ability to achieve stability through change.

Two formulas for computation of the area under the curve represent measures of total hormone concentration versus time-dependent change
TL;DR: It is shown that depending on which formula is used, different associations with other variables may emerge, and it is recommended to employ both formulas when analyzing data sets with repeated measures.
