Preliminary evidence for sleep complaints among children referred for anxiety

Background and purpose: Clinical observation suggests that sleep complaints are common among youth with anxiety disorders though empirical data documenting this co-occurrence of symptoms are generally unavailable. Patients and methods: Based on retrospective chart reviews, the current study examined rates of several types of parent-reported sleep complaints among a sample of (n=35) purely anxious children and adolescents (ANX). Sleep complaints were examined in terms of age (children versus adolescents) and type of anxiety diagnosis (generalized anxiety versus other anxious diagnoses). Rates of sleep complaints among anxious youth also were compared to those among (n =38) healthy control children and (n= 33) children referred for sleep problems. Results: The presence of at least one intermittent sleep complaint was reported by 83% of parents of ANX, with almost half reporting at least one frequent sleep complaint. Rates of sleep complaints among anxious children versus adolescents were similar. Children with generalized anxiety disorder (GAD) had a significantly greater number of sleep complaints than children with other types of anxiety disorders, though rates for specific items varied. Although parents of sleep-referred children reported the highest rates of sleep complaints overall, the frequency of several specific types of sleep complaints was highly similar among ANX and sleep-referred children. Conclusions: Findings indicate that certain sleep complaints are common among ANX. The need for appropriate assessment practices is discussed. (C) 2006 Elsevier B.V. All rights reserved.
