|Abstract:||Social Anxiety Disorder (SAD) is a psychological disorder characterised by an excessive and persistent fear of social or performance situations. Cognitive models of SAD have emphasised the importance of negative pre- and post-event rumination as a maintaining factor of SAD, however, little is understood about these cognitively important processes, and there is limited research in the area of pre-event rumination. The aims of this thesis were to critically evaluate the current empirical and theoretical literature regarding the process of negative rumination in SAD and then empirically investigate likely cognitive predictors of negative rumination. This thesis consists of two studies: a systematic review study and an empirical research study. The first study systematically evaluated existing research, which investigated cognitive predictors of rumination in SAD. Three of the 27 included studies investigated pre-event rumination, and results indicated that performance self-appraisal and fear of negative evaluation were the most commonly studied predictors of negative rumination. The second study aimed to address limitations in the current literature and examine several key hypotheses posited by the cognitive models of SAD. This study experimentally manipulated social standards in order to examine the impact of high and low perceived social standards on affective and cognitive processes in SAD, and to determine if the predictors of pre-event rumination would mirror those of post-event rumination. The sample consisted of 91 participants, including 46 participants with SAD and 45 non-anxious control participants. Whilst performance appraisal, threat appraisal, and state anxiety were found to predict pre-event rumination, threat appraisal was the only significant predictor of rumination after the social event. Our data is consistent with cognitive models and the interpretation that perceived inability to meet social and performance standards exerts maximum influence prior to and during an event and thereafter participants with SAD assume they have fallen short of the required standard and instead focus on the social threat of that perceived failure. This study lends support to contemporary theoretical models and extends the current knowledge of cognitive processes within SAD, which has important clinical implications. A comprehensive discussion of the results of the empirical study in relation to the cognitive models of SAD is included, and avenues for future research are discussed.|
