Insomnia in breast cancer: a prospective observational study.

Study Objectives: Insomnia in cancer patients is prevalent, persistent, and confers risk for physical and psychological disorder. We must better understand how insomnia develops in cancer patients and explore the main contributors to its chronicity so that insomnia management protocols can be integrated more effectively within cancer care. This study monitors the etiology of insomnia in breast cancer patients and identifies risk factors for its persistence.

Does cognitive behaviour therapy for insomnia reduce clinical levels of fatigue, anxiety and depression in cancer patients?

Objectives: This secondary analysis of data from a randomised controlled trial explores associations between common symptom clusters and evaluates pre-treatment to post-treatment changes in clinical levels of these symptoms following cognitive behaviour therapy for insomnia (CBT-I).

Methods: Baseline data from 113 participants with insomnia were explored to establish rates of and associations between clinical levels of fatigue, anxiety and depression across the sample. Effects of CBT-I on this symptom cluster were also explored by examining changes in pre-treatment to post-treatment levels of fatigue, anxiety and depression.
