Psychometric properties of component and global measures of structured interview assessed type A behavior in a population sample.
Structured interview (SI) assessments of global and component Type A behavior were conducted in a general population sample of 903 respondents. Correlations among all the measures were positive and significant. A factor analysis revealed that the common component variance was explained by a single underlying factor. Interrater reliabilities were approximately 0.5 to 0.7 for the individual components and 0.8 for both the SI global Type A and a second global measure that was assigned independently by assessors who did the component scoring. Prediction of the SI-assessed global measure from the components accounted for 56% of the variance, and prediction of the second global measure from the components accounted for about 83% of the variance. Implications of the psychometric properties of the SI component and global measures of Type A behavior for future research are discussed.
