In their cognitive model of social phobia, Clark and Wells (1995) described a process called post-event processing that is characterized by prolonged ruminative and negative thinking about a past social event. Referring to this concept, Rachman and colleagues (2000) developed a questionnaire that has been used in several studies subsequently (Post-Event Processing Questionnaire (PEPQ)). Our aim was to examine a German version of the PEPQ and, where necessary, modify this measure. In Study 1 (N=130 students), we inspected the psychometric properties of the German version of the PEPQ. According to the item analyses, problematic items were identified and eliminated or reformulated. To map aspects of post-event processing that were missing in the original questionnaire, new items were developed. In Study 2, the psychometric properties of the revised instrument were analyzed in a sample of students (N=268).The revised instrument showed excellent internal consistency and a meaningful pattern of correlations with anxiety, depression, and dysfunctional self-consciousness. With regard to the factorial structure of the construct, our data suggest that a four-factorial model may be more appropriate than the one-dimensional structure proposed by Rachman and colleagues.
