Clinical Trial Description

Insomnia is a common and problematic symptom in many psychiatric disorders. The aim of this study is to evaluate the effect of weighted chain blankets on insomnia and other sleep-related symptoms for patients with Major depressive disorder, Bipolar disorder, Generalized Anxiety Disorder (GAD) and/or ADHD. Potential participants are asked to participate in a study comparing two different types of chain blankets, not mentioning the difference in weight. After signing a informed consent, participants were randomly assigned on a 50/50 basis to a weighted blanket containing metal chains weighing 8 kg or a control blanket containing plastic chains weighing 1,5 kg. Insomnia severity is assessed before and weekly until endpoint at four weeks use of the blanket by a rater blind to treatment allocation. Participants sleep will also be monitored by actigraphy. The controlled phase of the study is followed by a one year open follow up study where all participants are offered to use a weighted blanket of any type. ;
