a For parents, the severity of anxiety symptoms is the combined total score of the State-Trait Anxiety Inventory for Adult-State-Anxiety scale (STAI-AD-SAI)[26] and the State-Trait Anxiety Inventory for Adult-Trait-Anxiety scale (STAI-AD-TAI)[26]; and the severity of depressive symptoms is the total score of the Beck Depression Inventory (BDI)[27]. For children, the severity of anxiety symptoms is the total score of the self-completion Screen for Child Anxiety Related Emotional Disorders (SCARED)[21]; and the severity of depressive symptoms is the total score on the Depression Self-Rating Scale for Children (DSRSC)[22]
