- Mean 10-Week Change in Pediatric Anxiety Rating Scale 5-Item Total Score, Double-blind Phase [ Time Frame: Weeks Baseline, 2, 4, 6, and 10 ]The Pediatric Anxiety Rating Scale (PARS) is a clinician-rated instrument that assesses anxiety symptoms that are commonly associated with social anxiety, separation anxiety, and generalized anxiety disorders. Scaled score ranges form 0-25 with higher scores indicating more severe anxiety symptoms. Means were estimated using a repeated measures linear regression model with treatment group, study week (in categories), and their interaction as covariates, and assuming a common mean between treatment groups at baseline. Confidence intervals reflect a Bonferroni multiple testing correction accounting for the selection of two primary outcomes.
- Proportion of Participants Who Responded to Treatment at 10 Weeks According to the Improvement Item of the Clinical Global Impression-Scale (Response Defined as CGI-I=1 or CGI-I=2) [ Time Frame: Screen (Visit 1) Baseline (Visit 2) and Endpoint (Week 10) ]The Clinical Global Impressions Global Improvement (CGI-I) is designed to take into account all factors to arrive at an assessment of response to treatment. The CGI-I scale ranges from 1 to 7 (1=very much improved; 2= much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse), with lower scores indicating improvement (1=very much improved and 2=much improved). In this study the CGI was focused on the target symptom of anxiety. Participants with a CGI-I score of 1 or 2 were classified as responders. The CGI-I was administered biweekly for 6 weeks and again at 10 weeks during the study. The participant who withdrew from the study before 10 weeks was not included in the calculations.
