The Impact of CBT-i on CPAP Therapy Use and Drop Outs in OSAS Patients With Insomnia.

The Impact of Cognitive Behavioral Therapy for Insomnia on CPAP Therapy Use and Drop Outs in Obstructive Sleep Apnea Syndrome Patients With Insomnia.

Patients follow the fully standard sleep test according to the normal procedure. This means that they undergo a polysomnography and fill in a questionnaire. If according to the questionnaire, there is insomnia, the patient also receives an intake interview to check whether this is indeed the case. If the patient has both disorders and meets the inclusion and exclusion criteria, they will be asked to sign the informed consent. If the patient agrees, the CPAP-therapy will be started as usual, simultaneously with CGT-i. The latter will last 7 weeks and will cover the following points: psycho-education, sleep restriction and sleep hygiene, cognition, relaxation and relapse prevention. Because of the design of this study (starting CGT-I as soon as possible after the diagnosis of OSAS) and the groups already planned for CBT-I, it is not possible for all participants to participate in group cognitive behavioral therapy, therefore individual sessions were provided for these participants. The patient comes for monitoring at set times.

Patients treated simultaneously with CPAP for their OSAS and cognitive behavioral therapy for their insomnia.
