Smartphone‐based virtual agents and insomnia management: A proof‐of‐concept study for new methods of autonomous screening and management of insomnia symptoms in the general population

Summary Insomnia is the most frequent sleep disorder, and the COVID‐19 crisis has massively increased its prevalence in the population, due to psychosocial stress or direct viral contamination. KANOPEE_2 is a smartphone‐based application that provides interactions with a virtual agent to autonomously screen and alleviate insomnia symptoms through an intervention programme giving personalized advices regarding sleep hygiene, relaxation techniques and stimulus‐control. In this proof‐of‐concept study, we tested the effects of KANOPEE_2 among users from all over the country (France) who downloaded the app between 1 June and 26 October 2020 (to focus on effects after the end of COVID‐19 confinement). Outcome measures include insomnia severity (Insomnia Severity Index) and sleep/wake schedules measured by a sleep diary. One‐thousand and thirty‐four users answered the screening interview (Mage = 43.76 years; SD = 13.14), and 108 completed the two‐step programme (Mage = 46.64 years; SD = 13.63). Of those who answered the screening, 42.8% did not report sleep complaints, while 57.2% presented mild‐to‐severe insomnia symptoms. At the end of the intervention, users reported significantly fewer sleep complaints compared with the beginning of the intervention (Insomnia Severity Indexbeginning = 13.58; Insomnia Severity Indexend = 11.30; p
