Patterns of Anxious Arousal During a Speech Task Between Nonanxious Controls and Individuals With Social Anxiety Disorder Pre- and Posttreatment. Behav Ther. 2017 Nov;48(6):765-777 Authors: Lee CS, Wadsworth LP, Hayes-Skelton SA Abstract Although research indicates that anxious arousal in response to feared stimuli is related to treatment outcome (Heimberg et al., 1990), less is known about the patterns of anxious arousal. We identified patterns of anxious arousal in individuals with social anxiety disorder (SAD) at pre- (n= 61) and posttreatment (n= 40; 12-session CBGT, Heimberg & Becker, 2002), and in non-anxious controls (NACs; n= 31) using an assessment speech task administered at pretreatment (SAD) or the pretreatment equivalent (NACs), as well as at posttreatment (SAD only). We identified nine patterns of anxious arousal across groups that we further clustered into three groups: fear habituation, fear plateau, and fear increase. Chi-square and adjusted standardized residual analyses revealed that individuals in the pretreatment SAD group displayed the fear habituation patterns significantly more than chance and the fear plateau patterns significantly less than chance. In contrast, NACs displayed the fear plateau patterns significantly more than chance and the fear habituation patterns significantly less than chance. At posttreatment, treatment non-responders displayed fear habituation patterns significantly more than chance...
