Exploring the Cyclical Relationship of Self- and Other-Evaluations and its Impact on Cognitive, Behavioural, and Emotional Outcomes in Social Anxiety

Abstract

Cognitive models of Social anxiety disorder (SAD) routinely discuss the cognitive biases (e.g., attentional, interpretation, memory) that contribute to thinking about oneself negatively before, during, and after social or performance situations. However, these models do not mention other impacts of negative self-evaluations - including negative evaluations of others - even though cognitive case formulations often include beliefs about oneself, others, the future, and the world. Importantly, CBT for SAD does not always lead to optimal subclinical symptoms at the end of treatment; suggesting that our most evidence-based treatments require modifications. Few studies have experimentally examined the presence of negative evaluations of others within social anxiety, which has led to inconsistent understanding about whether people with social anxiety demonstrate negative evaluations of others. These conflicting findings are even more complicated by no study examining if the negative self-evaluations that are commonly reported by people with SAD cause negative other-evaluations, and vice-versa. I outline two studies in this dissertation where I aimed to understand the relationship (or lack thereof) between negative self-evaluations and negative other-evaluations and its cognitive, behavioural, and emotional consequences. In Study 1, I randomly assigned an unselected sample (N = 152) to provide no-, medium-, or high-evaluations of a videotaped anxious person. Participants also took part in a 10- minute conversation task with a confederate posing as another participant. I measured social anxiety symptoms, state anxiety and electrodermal activity across four-time points, and several measures related to self- and other-evaluations. Overall, my manipulation was effective as participants responded to the subsequent other-evaluations in the way I anticipated. Despite this, I found no differences between conditions on most of my primary self-evaluation outcomes. However, I observed that participants in the high-evaluation condition demonstrated poorer memory recall. In Study 2, I randomly assigned an unselected sample (N = 169) to receive positive, ambiguous, or negative false-feedback following a conversation task with a confederate. My manipulation was effective, and again, I found no differences between conditions on my primary other-evaluation outcomes. Participants in the negative-feedback condition reported greater state anger following the negative evaluation for the remainder of the study, compared to participants in the other conditions. Ultimately, evaluations of others were less problematic than I initially expected. Because I did observe cognitive and emotional consequences of this self-other process, these findings could have important implications for further refinement of SAD models and treatments using Cognitive Behavioural Therapy.
