Impairment in childhood anxiety disorders: preliminary examination of the child anxiety impact scale-parent version

Abstract

Although anxiety disorders are prevalent among children and adolescents, with a chronic and often disabling course, there is a paucity of research examining the specific ways in which anxiety interferes with various domains of functioning in childhood. The purpose of the current investigation was to examine the initial reliability and construct validity of the Child Anxiety Impact Scale-Parent version (CAIS-P). The CAIS-P is a parent-report measure consisting of School, Social, and Home/Family subscales. In a clinical sample (N = 92), the internal reliability and the convergent and divergent validity were evaluated. Internal consistency was good for the total score as well as each subscale (Cronbach's alpha ranged from 0.73-0.87). The CAIS-P total score demonstrated good construct validity, showing predicted significant correlations with the Child Behavior Checklist Internalizing Scale and the Child Depression Inventory but not the Externalizing Scale of the Child Behavior Checklist. The Social subscale of the CAIS-P was also significantly correlated with measures of social anxiety. The results provide initial support that the CAIS-P is a reliable and valid measure for the assessment of the impact of anxiety on child and adolescent functioning.
