Means (M), standard deviations (SD), Wilcoxon test and effect sizes (Cohen’s d) for transdiagnostic (PANAS, CASI and EASI) and disorder-specific (PDSS-SR, PSWQ-N, and SASC-R) outcome measures.

Note. ^a Z Wilcoxon test based on positive ranks (exact signification, 1-tailed) (for PANAS-PA, the Z score was based on negative ranks). ^b Z values are identical to those of the completer sample. CASI = Childhood Anxiety Sensitivity Index; EASI-A = Emotional Avoidance Strategy Inventory for Adolescents; FNE = Fear of Negative Evaluation; PANASN-NA = Negative Affect scale of the Positive and Negative Affect Schedule for Children and Adolescents; PANASN-PA = Positive Affect scale of the Positive and Negative Affect Schedule for Children and Adolescents; PDSS-SR = Panic Disorder Severity Scale—Self-Report; PSWQ-N = PSWQ-11 questionnaire for children and adolescents; SASC-R = Social Anxiety Scale for Children—Revised. ⁺ p < 0.10; * p < 0.05; ** p < 0.01.
