Abstract
STUDY OBJECTIVES: To examine differences in sample characteristics and longitudinal sleep outcomes according to weighted blanket (WB) adherence. METHODS: Children with attention-deficit/hyperactivity disorder (n = 94), mean age 9.0 (standard deviation 2.2, range 6-14) participated in a 16-week sleep intervention with WBs. Children were classified as WB adherent (use of WB ≥ 4 nights/wk) or nonadherent (use of WB ≤ 3 nights/wk). Changes in objectively measured sleep by actigraphy, parent-reported sleep problems (Children's Sleep Habits Questionnaire) and child-reported Insomnia Severity Index were evaluated according to adherence with mixed effect models. Sex, age, and attention-deficit/hyperactivity disorder subtype were examined as potential moderators. RESULTS: Children adherent to WBs (48/94) showed an early response in sleep outcomes and an acceptance of the WB after 4 weeks of use as well as a decrease in parent-reported (Children's Sleep Habits Questionnaire) (-5.73, P = .000) and child-reported (Insomnia Severity Index) (-4.29, P = .005) sleep problems after 16 weeks. The improvement in sleep was larger among WB adherent vs nonadherent (between-group difference: Children's Sleep Habits Questionnaire: -2.09, P = .038; Insomnia Severity Index: -2.58, P = .007). Total sleep time was stable for children adherent to WB but decreased for nonadherent (between-group difference: +16.90, P = .019). CONCLUSIONS: An early response in sleep and acceptance of the WB predicted later adherence to WBs. Improvements in sleep were more likely among WB adherents vs nonadherents. Children with attention-deficit/hyperactivity disorder may thus benefit from using WBs to handle their sleep problems. CITATION: Lönn M, Svedberg P, Nygren J, Jarbin H, Aili K, Larsson I.
