RESUMO
Relationship quality is a strong predictor of health outcomes, and individuals with social anxiety disorder (SAD) report increased interpersonal impairment. However, there are few studies testing the effect of SAD on friendships and it is thus unclear whether there are behavioral differences that distinguish friendships in which a target individual has SAD from friendships in which the target individual does not have SAD. We tested for differences in the provision and receipt of support behaviors as a function of having a SAD diagnosis and accounting for comorbid depressive symptoms. Participants with SAD (n = 90) and their friends engaged in support conversations that were coded using the Social Support Interaction Coding System. Structural equation modeling revealed some differences between participants and friends when accounting for depression. Specifically, friends of participants with SAD and comorbid depression engaged in fewer positive helper behaviors than the friends of participants who did not have SAD or comorbid depression. Additionally, dyads in which the primary participant had SAD engaged in more off-task behaviors. Results suggest that SAD does not result in global interpersonal impairment, but that receipt of positive support behaviors from friends may differ as a function of SAD and comorbid depression. Interpersonal interventions aimed at increasing adaptive friendships and aspects of CBT that target subtle avoidance (e.g., safety behaviors) may be useful in facilitating more satisfactory relationships for these individuals.
