Anxiety in children attending a specialist inherited cardiac arrhythmia clinic: a questionnaire study

Abstract

Objectives Inherited cardiac arrhythmia syndromes are life-threatening conditions. There is a paucity of research examining the psychological impact of these conditions in children. This study had three main aims. The first was to explore how the Cardiac Anxiety Questionnaire (CAQ) performs in a child population. The second aim was to compare the level of anxiety of children with an inherited cardiac arrhythmia syndrome and children being screened due to a family history of an inherited cardiac arrhythmia syndrome to control children. The third aim was to examine associations between a sudden cardiac death in the immediate family and levels of anxiety.Method 47 children with an inherited cardiac arrhythmia syndrome, 78 children with a family history and 75 control children completed the Revised Child Anxiety and Depression Scale (RCADS), the Cardiac Anxiety Questionnaire for Children (CAQ-C) and the Childhood Anxiety Sensitivity Index. Children were between the age of 8 and 16 years.Results The study found the CAQ-C had promising psychometric properties. There were no significant differences in total anxiety scores (as measured by the RCADS) between the three groups. There were significant differences in cardiac-focused anxiety scores between the three groups.Conclusions The CAQ has promising psychometric properties in a child population. However, further research is needed. Children attending specialist inherited cardiac arrhythmia clinics should be targeted for routine psychological screening and offered psychological intervention where necessary.
