TL;DR: The findings of this study support those of recent studies that have identified null effects of Type D on outcome when analysed as a dimensional construct.
Abstract: Objective: Type D personality, the interaction of negative affectivity (NA) and social inhibition (SI), has been associated with a range of adverse health-related outcomes in cardiac patients and healthy participants. However, recent studies which have adopted a dimensional approach to Type D found no effect of Type D (NA × SI) on mortality or quality of life, after controlling for its constituent elements. To date, no study has determined if Type D is associated with negative health outcomes in healthy individuals when conceptualised as a dimensional variable.Design: A cross-sectional self-report study with 177 healthy participants.Main Outcome Measures: Physical symptoms and quality of life.Results: Using the traditional categorical analysis for Type D, it was found that Type D’s report significantly more symptoms and significantly lower quality of life than non-Type D’s report. However, when analysed as a dimensional construct (NA × SI), using multiple regression analysis, Type D (NA × SI) was not a si...

TL;DR: Synergistically analyzed type D personality was not associated with 10-year all-cause mortality in PCI patients whereas dichotomous type D was, however, after adjustment for depression most of the findings had disappeared.

TL;DR: Type D personality and high NA both have a significant negative stable impact on HRQoL and disease-specific health status among CRC patients.
Abstract: Background. Prospective studies in various cardiovascular populations show that Type D personality predicted impaired health-related quality of life (HRQoL) and disease-specific health status. We examined the effect of negative affectivity (NA), social inhibition (SI) and their combined effect (Type D personality) on HRQoL and disease-specific health status among colorectal cancer (CRC) patients.Methods. CRC patients diagnosed between 2000 and 2009, as registered in the Dutch population-based Eindhoven Cancer Registry, received questionnaires on Type D personality (DS14), HRQoL (EORTC QLQ-C30) and disease-specific health status (EORTC QLQ-CR38) in 2010, 2011 and 2012.Results. Response rates were 73% (n = 2625), 83% (n = 1643) and 82% (n = 1458), respectively. Analyses were done on those completing at least two questionnaires (n = 1735). Individuals with Type D (NA+/SI+; 19%) and high NA (NA+/SI-; 11%) reported a significantly worse HRQoL and disease-specific health status compared to NA-/SI+ and N...

TL;DR: The outcomes support prior research evidencing that whilst Type D personality is related to poor sleep in adolescents, NA appears to be the main contributor.

TL;DR: 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 ...

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.
Abstract: Objective: Type D personality is characterised by negative affectivity (NA) and social inhibition (SI), and is often associated with poorer physical and psychological health. However, the underlyin...
