Abstract
BACKGROUND: Insomnia is very common, especially among psychiatric patients in secondary care. It is experienced as a 24 h problem affecting several domains of life. Cognitive behavioural therapy for insomnia (CBT-I) is widely regarded as the first-line treatment and often improves comorbid disorders. Despite this, many patients are not offered CBT-I. Internet based CBT for insomnia (iCBT-I) is just as effective as face-to-face treatments and could considerably increase availability. However, it is unclear whether iCBT-I is suitable for patients with more severe and comorbid psychiatric illnesses in secondary care. METHODS: Eleven Swedish participants (24-68 years old) in outpatient secondary psychiatric care who underwent iCBT-I treatment were interviewed. The semi-structured interviews were analysed using content analysis. The purpose was to map their experiences, motivation and suggestions for improvement. RESULTS: Prior to the treatment, most participants were highly motivated to take the opportunity to address their insomnia. The treatment was perceived as well-structured and interesting. The most difficult aspect was counteracting the fatigue. It was also hard to continue the treatment when faced with major life events. During this phase, contact with the therapist motivated them to continue the treatment. Several desired more face-to-face meetings. It was also motivating to gain insights into and a sense of control over sleep. Several described better sleep, improved daily routines, a more predictable everyday life and increased energy. Daytime well-being was improved in some, partly because they had more energy but also because they filled their days with more activities. CONCLUSION: The treatment has the potential to be very useful in secondary psychiatric care where insomnia is common and affects comorbid disorders. Psychiatric patients might have more difficulties continuing with iCBT-I treatment, but those who manage to complete the program have a good chance of obtaining benefit. Extensive psychological groundwork early in treatment is likely to pay off later when motivation is needed. Additional social support and other adjustments may also enhance treatment outcomes. Participants' stories are particularly valuable, as therapists and treatment developers receive less feedback from patients in internet-based treatments compared to face-to-face treatments.
