Evaluation der deutschen Typ-D-Skala (DS14) und Prävalenz der Typ-D-Persönlichkeit bei kardiologischen und psychosomatischen Patienten sowie Gesunden

Abstract

The Type D personality pattern, consisting of negative affectivity and social inhibition, has been shown by Denollet et al. to predict adverse prognosis in patients with coronary heart disease. For measuring the Type D characteristics, Denollet has devised the 14 item Type D scale (DS14). In the present study, this instrument was translated into German. The validity, reliability and adequacy of the German DS14 were then tested in 2421 persons, including cardiological and psychosomatic patients as well as healthy factory workers. The results document sound psychometric properties of the scale. Cronbach's alpha was 0.87 for the negative affectivity subscale and 0.86 for social inhibition. The two-factor structure of the original instrument could be clearly replicated. The prevalence rates of the Type D pattern were lowest in cardiological patients (25 %) and highest in psychosomatic patients (62 %). The prevalence in this German sample of cardiology patients was also lower than the one observed in healthy factory workers (32.5 %) and in CHD samples reported in the literature. These group differences could not be accounted for by differences in age and sex distribution. In conclusion, the DS14 is a valid and reliable instrument that can be used for an economic evaluation of the Type D characteristics in patients and healthy persons. The possible meaningfulness of the low Type D prevalence in cardiac patients and the prognostic relevance of this pattern require further study.

Type D personality in cardiovascular patients and general population: prevalence and retrospective perception of stability

“…This was similarly reported by Grande et al (2004), who found the prevalence of Type D personality in psychosomatic patients being 62%. Possibly, those patients experience more distress that links both to mental health impairment and Type D.…”

Negative affectivity and social inhibition in cardiovascular disease: Evaluating type-D personality and its assessment using item response theory

“…It has been argued that psychological research needs to explore newer personality constructs such as type-D to see how such constructs may contribute to our understanding of the pathogenic effects of personality on the development and progression of heart disease [49]. Accumulated evidence suggests that type-D personality is associated with increased risk of mortality, morbidity, and impaired quality of life in cardiac patients [50], and that the type-D construct is equally applicable across different nationalities (e.g., [51,52]). …”

Type D Personality as a Cardiovascular Risk Marker in the General Population: Results from the Gutenberg Health Study

“…Type D personality was assessed with the German version of the DS14 [1,5]. The DS14 comprises two reliable subscales with 7 items each for negative affectivity and social inhibition, rated on a 5-point Likert scale (0 = false to 4 = true).…”

“…Type D subjects were less educated and had a lower income in an age-adjusted analysis. Somewhat higher prevalence rates were found among clinical groups: in cardiovascular patients, these ranged from 24.8% in Germany (n = 1,196 [5]) to 28% in Belgium (n = 358 [1]). However, the highest rates, i.e.…”
