Ecological momentary assessment of post-event processing in between two speech tasks: Relationships with cognitive and affective factors involved in the maintenance of social anxiety

Socially anxious individuals tend to review past distressing social situations, a process called post-event pro-cessing. The goal of this 4-day study was to investigate how PEP evolved over time in between two speech tasks in a sample of 101 students using ecological momentary assessment (EMA). In addition, we examined the re-lationships between post-event processing and other cognitive and affective processes involved in social anxiety, including anticipatory processing, anxiety, performance appraisals, and memory. Results from EMA showed that post-event and anticipatory processing decreased over time. Higher anxiety during the speech and poorer per-formance appraisals predicted more post-event processing, though post-event processing was unrelated to changes in performance appraisals over time. Post-event processing the day following the first speech was positively associated with anticipatory processing the day before the second speech. Participants who engaged in more post-event processing also remembered the first speech differently (e.g., more negative and emotionally intense). Implications for the cognitive-behavioural treatment of social anxiety are discussed.
