Why the study?
Does the Type D personality construct correlate with emotional distress in patients with coronary artery disease?
Does the Type D personality construct correlate with emotional distress in patients with coronary artery disease?
The social inhibition component of Type D personality is a distinct trait that, along with negative affectivity, is associated with increased emotional distress in coronary artery disease patients.
Supports distinct social inhibition assessment in CAD Type D screening; hypothesis-generating for emotional distress interactions, needs prospective validation.
We examined the validity of the social inhibition component of Type D, its distinctiveness from negative affectivity, and value regarding emotional distress as measured with the DS14 in 173 coronary artery disease patients. In dimensional analysis, social inhibition and negative affectivity emerged as distinct traits. Analysis of continuous negative affectivity and social inhibition measures showed main effects for several emotional and inhibition markers and an interaction effect for social anxiety. Categorical analysis indicated that Type D patients reported more depression, negative mood, social anxiety, and less positive mood. Social inhibition is not a redundant trait, but has additional conceptual value.
