SLEEPexpert plus : Blending Internet-Based Cognitive Behavioral Therapy for Insomnia with In-Person Psychotherapy-A Feasibility Study in Routine Care

Insomnia is characterized by frequent and persistent difficulties initiating and maintaining sleep, along with impaired daytime functioning. Blended treatments are increasingly popular for treating psychological disorders such as depression. Blended treatments combine elements of face-to-face therapy and online interventions. A single-arm pre-post study investigated the feasibility of a blended treatment combining face-to-face cognitive behavioral therapy for insomnia and internet-based cognitive behavioral therapy for insomnia (SLEEPexpert+). The findings show that the therapists have a positive attitude toward blended CBT-I (b-CBT-I) and that they feel supported by the online components of the treatment. Possible barriers to implementing blended treatments are integrating the online materials into the face-to-face sessions and adapting one's therapeutic style to the blended treatment approach. No definitive statements about the effectiveness of the b-CBT-I treatment can be made. However, of the six presented cases, five patients showed notably higher sleep efficiency and fewer insomnia symptoms at the end of the therapy. Program usage data indicate that participants mainly used the online components at the beginning of their treatment. Future studies should investigate the effectiveness of b-CBT-I with a sufficiently powered randomized controlled trial comparing b-CBT-I with an adequate control group in routine care.
