The relation between type A behavior and chronic emotional distress: a meta-analysis.

A meta-analysis was conducted of studies examining the relation between Type A behavior and chronic emotional distress as measured by standard psychological scales. Aggregating across all studies, the average effect size was .27, indicating a positive association between Type A and chronic dysphoria; however, there was considerable variability in the size of the relation among studies. Partitioning by Type A measure revealed that Structured Interview-assessed Type A was unrelated to chronic dysphoric emotions; however, most of the self-report measures of Type A behavior were moderately correlated with upset. The Framingham Type A Scale and the Bortner Scale showed the strongest relations. Thus, contrary to the traditional view, Type A measured by self-report does have some emotional concomitants, although they are not in the pathological range. Also discussed are how the results bear on the proposal that the maladjusted personality confers coronary risk, the implications for reported associations between Type A and illness complaints, and for the study of the Type A as a social psychological construct.
