CBT-I Modifications in Cancer Patients
Cognitive Behavioral Therapy for Insomnia is the first line treatment for insomnia in cancer patients. It is effective in improving insomnia, specially reducing time it takes to fall asleep, nighttime wakenings, and early morning wake ups. It is beneficial in reducing cancer related fatigue, lowering symptoms of depression and anxiety and overall improving quality of life. This finding is both robust and durable (e.g., Squires et al., 2022).
General modifications for CBT-I in cancer patients include prioritizing flexibility, symptom monitoring, and reducing the intensity of treatment. It requires a gentler approach, and requires focus on secondary insomnia drivers relevant in cancer including pain, anxiety, and medication side-effects.
Adaptation of Core Components:
Sleep Restriction: In the general population, sleep restriction is highly rigid to consolidate sleep. For cancer patients undergoing treatments, strict sleep restriction can exacerbate debilitating fatigue. Modifications involve setting a more generous minimum time in bed (often 5.5 to 6 hours) and adjusting bedtimes dynamically based on daily treatment side effects.
Stimulus Control: Standard rules (e.g., "get out of bed if you haven't fallen asleep in 15 minutes") may be modified if patients are experiencing severe pain, neutropenia, or extreme physical weakness. The goal shifts from strict compliance to reducing "bed-waking" anxiety.
Cognitive Restructuring: Focuses heavily on reframing cancer-related intrusive thoughts—such as hyper-vigilance about the disease, scan-related anxiety, or feelings of bodily betrayal—rather than just classic sleep-related performance anxiety.
Sleep Hygiene: Incorporates management of cancer-specific sleep disruptors, such as frequent nighttime awakenings due to steroid-induced restlessness (e.g., dexamethasone), bone pain, or hot flashes.
Modifications in Treatment Delivery:
Abbreviated treatment format
Involvement of caregivers
Virtual care and telehealth options
