Figure 2. End Fear Moderating the Effect of D-cycloserine Augmentation of Cognitive Behavioral Therapy for Social Anxiety Disorder on Clinical Improvement at the Next Session.

Note. CGI-I is the Clinical Global Impressions Improvement scale that uses a 7-point scale, with lower scores indicating greater improvement (1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse). End Fear is the fear rating provided just prior to concluding the exposure exercises. Fear ratings were assessed using the subjective units of distress scale (SUDs; Wolpe, 1958), which ranges from 0 to 100 (0=no fear, relaxed; 25=mild fear, able to cope; 50=moderate fear, trouble concentrating; 75=severe fear, thoughts of leaving; 100=very severe fear, worst ever experienced), and thus low ratings indicate exposure success and higher ratings indicate less exposure success.
