Intra- and Interpersonal Consequences of Social Anxiety Disorder on the Physiological, Behavioral, and Psychological Level

Social anxiety disorder (SAD) is a disorder characterized by impairments in interpersonal functioning such as experiencing difficulties in forming and maintaining relationships. These impairments have negative intrapersonal consequences for individuals with SAD on different levels such as the physiological, behavioral, and psychological level. A newer perspective on SAD has suggested that it also negatively impacts the interaction partner (i.e. interpersonal consequences of the disorder). According to this perspective, certain verbal and nonverbal behaviors and thought or feeling content of the healthy interaction partner are affected while interacting with an individual who have SAD. The current study investigated the intra- and interpersonal consequences of SAD on the physiological, behavioral, and psychological level during initial interactions. Participants played a dyadic trust game (23 same-gender dyads) while their electrodermal activity (EDA) was continuously measured and...Show moreSocial anxiety disorder (SAD) is a disorder characterized by impairments in interpersonal functioning such as experiencing difficulties in forming and maintaining relationships.

A newer perspective on SAD has suggested that it also negatively impacts the interaction partner (i.e. interpersonal consequences of the disorder). According to this perspective, certain verbal and nonverbal behaviors and thought or feeling content of the healthy interaction partner are affected while interacting with an individual who have SAD. The current study investigated the intra- and interpersonal consequences of SAD on the physiological, behavioral, and psychological level during initial interactions. Participants played a dyadic trust game (23 same-gender dyads) while their electrodermal activity (EDA) was continuously measured and filled in self-report measures during and after the game. The dyads consisted either of one participant scoring high on social anxiety (SA) and one low on SA (i.e. SA dyads) or two participants scoring low on SA (i.e. control dyads). EDA was used as the measure on the physiological level, participants’ trust ratings were the measure on the behavioral level, and the discrepancy between self and partner reports on positive/negative personal attributes to explore cognitive biases was the measure on the psychological level. We expected to observe higher EDA synchrony, lower trust ratings, and higher discrepancy between self and partner reports in SA dyads compared to control dyads. Results showed no difference between dyads on all levels indicating that we were not able to observe the predicted effect of finding intra- and interpersonal consequences of SAD in SA dyads. The most important implication of the current study is that, it included three different levels of SAD, in contrast to earlier studies that mainly focused on one level. This provides a useful example for how future studies might be designed and conducted.Show less
