A psychometric study was conducted with the aim of collecting basic information about anticipatory processing and its relationship to social anxiety. A self-report measure of anticipatory processing was developed and utilized in a large student sample. The results confirmed that such processing is very common before an anticipated feared social event and a significant correlation (r=0.49) between anticipatory processing scores and social anxiety was found, which remained when trait anxiety and depression were controlled. A factor analysis indicated that all items of the measure except for two loaded significantly on one factor and accounted for the 47.3% of the variance. Socially anxious individuals in the study reported that their thoughts about the event were recurrent, intrusive, interfered with their concentration and increased their state of anxiety. Also, they reported that they wished they could avoid the situation. The results are discussed in terms of the Clark and Wells cognitive model of social phobia.
