Attention-Affect Check List: A self-report measure of acute mental stress.

Abstract

Given a hint from Lang, Bradley, and Cutbert's (1997) defense cascade, two cognitive processes, instead of passive versus active behavioral coping, which seem to have differential effects on the provocation of vascular- versus cardiac-dominant reaction pattern during mental stress were advocated: attention (Attent) versus unpleasant affect (UnplAff). Based on this notion the Attention-Affect Check List (AACL) was developed as a self-report measure. In addition, items on uncontrollability (Uncontr) were prepared for the purpose of checking whether heightened Attent and UnplAff are accompanied by alterations in Uncontr. Two hundred and eighty-four students underwent two kinds of mental stress, which seemed to specifically heighten Attent and UnplAff. Four factors with four items each were extracted from the AACL item pool: concentrated and allocated Attent, UnplAff, and pleasant affect. Also, one factor with four items was extracted from the Uncontr item pool. For both the mental stresses, each scale, although very brief, had quite reasonable alpha reliability. Accountability of each scale for the total variance was reasonably high. Some problems are discussed in relation to the validity of AACL.
