Quesnel, C., Savard, J., Simard, S., Ivers, H., & Morin, C. M. (2003). Efficacy of cognitive-behavioral therapy for insomnia in women treated for nonmetastatic breast cancer. Journal of Consulting and Clinical Psychology, 71, 189–200.doi: 10.1037/0022-006X.71.1.189
The study used a two-phase, multimodal, cognitive-behavioral therapy (CBT) combined strategy: (a) over 3 to 10 weeks and (b) over eight weeks; eight weekly sessions lasted 90 minutes.
The purposes were to establish treatment objectives, stimulus control, sleep restriction, coping strategies for fatigue, and reframe maladaptive cognitions.
Outcomes were sleep, mood, fatigue, and global and cognitive quality of life (QOL).
Patients were undergoing the long-term follow-up phase of care.
The study used a prospective, nonrandomized, repeated measures, quasiexperimental, single-case design comparing each individual over time.
Most women experienced a statistically significant improvement in sleep efficiency and decreased total wake time pre- and posttreatment. Sleep efficiency continued at the six-month follow-up, but total wake time did not. Findings on sleep diaries were corroborated by objective measures.
