Mind, Body and Machine: Preliminary Study to Explore Predictors of Treatment Response After a Sleep Robot Intervention for Adults with Insomnia.

"Disclosure The authors have no conflicts of interest to declare."

"In the original study, a pre-registered randomized waitlist-controlled trial (n = 44) was conducted to evaluate the effects of an at-home intervention with a sleep robot (Somnox) for three weeks (n = 22) compared with the waitlist control group (n = 22). The study complied with the Declaration of Helsinki. The Swedish Ethical Review Board approved the study project (DNR 2020–069759), which was conducted in Karlstad, Sweden in 2021. Informed consent was obtained from participants prior to the start of the study. The trial was registered in the ISRCTN registry (ISRCTN35134834). In the current study, data were pooled from both the intervention and the waitlist control group when the control group had also received the robot intervention. Differences between responders and non-responders regarding baseline demographics and clinical characteristics were analyzed, as these variables constitute potential predictors of treatment response."
