Antecedents, concomitants, and consequences of pediatric headache: Confirmatory construct validation of two parent-report scales

The aim of the study presented is to examine the psychometric properties of two parent-report scales for the assessment of environmental factors in pe diatric headache, namely, the Children's Headache Assessment Scale (CHAS) a nd the Illness Behavior Encouragement Scale (IBES). Data were gathered in a sample of 160 parents of children suffering from headaches regularly. The internal structure of both scales is investigated by means of confirmatory factor analysis. The internal consistency of the resulting subscales is exp lored and data on the convergent validity and on the relationship with demo graphics are presented. Both the CHAS and the IBES appear to be promising a ssessment tools in a behavioral approach to pediatric headache.
