Type A behavior, attentional style, and symptom reporting among adult men and women.

Type A behavior and its components (measured on the JAS) were examined in relation to attentional style and symptom reporting in 294 healthy adult men and women. The results showed that for both men and women the JAS Type A, Job Involvement, and Hard Driving factors were all associated with self-reported attentional effectiveness as measured by the Nideffer Test of Attentional and Interpersonal Style. However, a fourth JAS factor, Speed and Impatience, was associated with Nideffer measures of cognitive overload. For both men and women, the Type A, Speed and Impatience, and Hard Driving factors were all positively associated with the number of medical and psychological symptoms reported on the Cornell Medical Index. In addition, acute psychological distress (Hopkins SCL-90R) was associated with Type A behavior for men and with Speed and Impatience for both sexes. Attention differences did not account for the observed positive relationships between Type A factors and symptom reporting with one exception; attentional overload (internal) appeared to partially explain the relationships between symptom reporting and Speed and Impatience in women. In summary, Type As described themselves as having a broader attentional focus and reported more naturally occurring physical and psychological symptoms than did Type Bs.
