ABSTRACT
Background/Objective: Insomnia is common among adults with asthma and is associated with worse asthma control. Cognitive-behavioral therapy for insomnia (CBT-I) is an effective treatment for insomnia with medical comorbidities, but it has not been tested in asthma. The purpose of this study was to assess the feasibility and acceptability of an Internet-based CBT-I intervention, called Sleep Healthy Using the Internet (SHUTi), among adults with asthma and comorbid insomnia, and to gather preliminary efficacy data on changes in insomnia severity, sleep quality, asthma control, and asthma-related quality of life. Methods: A single-group, pretest–posttest design was employed, where all participants completed the SHUTi program. Online questionnaires were completed pre- and postintervention. Individual telephone interviews were conducted after posttreatment data collection to obtain participants’ experiences with SHUTi and suggestions for improvement. Results: The sample (N = 23) comprised men and women aged 18–75 years with moderate to severe, not well-controlled asthma, and comorbid insomnia. Nineteen (83%) completed postintervention assessments. Improvements on the Insomnia Severity Index, Pittsburgh Sleep Quality Index, Asthma Control Test, and Asthma Quality of Life Questionnair–Marks were observed at postintervention. Data from the telephone interviews suggest that most participants had a positive experience with SHUTi. Participants suggested incorporating asthma-specific content into future versions of the intervention. Conclusions: Internet-based CBT-I is a potential treatment option for adults with asthma and comorbid insomnia.
