Cross-informant agreement in the assessment of social phobia in youth.

In the present study involving children and adolescents with a principal diagnosis of social phobia, we measured parent-child agreement regarding social anxiety symptoms. Additionally, we examined variables related to the severity of the children's social phobia symptoms as reported by children and as rated by clinicians. Examination of cross-informant agreement indicated little difference between mean parent and children ratings of the children's social fears. In contrast, there was a significant difference in parent and children ratings of the children's avoidance, with parents endorsing greater degrees of social avoidance. Children's report of social avoidance was negatively related to scores on a measure of self-presentational concerns (i.e., social desirability). Clinicians' determination of the severity of the children's social phobia was also influenced by the children's self-presentation as well as parent report of social avoidance and children's depression scores. Thus, this differential weighting by the clinician of parent versus child report may be related to the finding that children's self-reported social avoidance was negatively related to their concerns regarding positive self-presentation. Results suggest the need to consider the impact of social desirability when examining clinical characteristics of children and adolescents with social phobia.
