Cognitive Behavioral Therapy for Insomnia in Cancer Survivors
Summary
Insomnia is a pervasive and persistent issue among individuals who have completed cancer treatment, with estimates indicating that up to two-thirds of survivors experience clinically significant sleep disturbance. Cognitive Behavioural Therapy for Insomnia (CBT-I) is a structured, non-pharmacological intervention designed to address maladaptive thoughts and behaviours that perpetuate poor sleep. Core components include stimulus control (strengthening the bed–sleep association), sleep restriction (limiting time in bed to consolidate sleep), cognitive restructuring (challenging unhelpful beliefs about sleep), relaxation training and sleep hygiene education. CBT-I can be delivered individually, in groups or via digital platforms, and may be adapted into brief formats suitable for oncology settings. Clinical outcomes typically encompass reductions in sleep onset latency and wake after sleep onset, increases in total sleep time and enhancement of sleep efficiency. Beyond sleep metrics, participants frequently report improvements in mood, fatigue, cognitive functioning and overall quality of life. Implementation within survivorship care pathways offers a scalable approach to mitigate the long-term physical and psychological sequelae of cancer-related insomnia.

Technical terms
Cognitive Behavioural Therapy for Insomnia (CBT-I): A multi-component treatment targeting the cognitive and behavioural factors that maintain insomnia, using methods such as stimulus control, sleep restriction and cognitive restructuring.
Insomnia Severity Index (ISI): A seven-item self-report scale that assesses the nature, severity and impact of insomnia symptoms and tracks changes over time.
Circadian Rhythm: The endogenous, approximately 24-hour cycle regulating sleep–wake patterns and other physiological processes, which can be disrupted by cancer and its treatments.
