NCT04026048

Brief Summary

The investigators will answer the question of whether treating insomnia using Cognitive Behavior Therapy for Insomnia (CBT-I) can improve perceived cognitive impairment (PCI) in cancer survivors compared to a waitlist control group. The investigators will recruit 124 people with insomnia and cognitive complaints who have completed cancer treatment at least 6 months prior to the study.

Outcome Measures

Primary Outcomes (1)

  • The Functional Assessment of Cancer Therapy - Cognitive Function (FACT-Cog) Version 3

    The FACT-Cog was used to measure perceived cognitive impairment (PCI). It is a 37-item questionnaire with four cognitive subscales: perceived cognitive impairments, impact on quality of life, comments from others, and perceived cognitive abilities. Responses range from 0, ''never,'' to 4, ''several times a day,'' in the previous 7 days and negatively worded items are reverse scored to create subscale scores. Scores on the PCI subscale can range from 0 to 72 points, with a higher score indicative of better self-reported cognitive functioning and quality of life. A change of 5.9-points has been established as clinically meaningful change on the FACT-Cog PCI subscale

    Change from Baseline to Week 4, Week 8, 3 month follow up, 6 month follow up

Secondary Outcomes (13)

  • The Insomnia Severity Index (ISI)

    Change from Baseline to Week 4, Week 8, 3 month follow up, 6 month follow up

  • Sleep Efficiency Measured by The Consensus Sleep Diary (CSD)

    Change from Baseline to Week 4, Week 8, 3 month follow up, 6 month follow up

  • Sleep-onset Latency Measured by The Consensus Sleep Diary (CSD)

    Change from Baseline to Week 4, Week 8, 3 month follow up, 6 month follow up

  • Wake After Sleep Onset Measured by The Consensus Sleep Diary (CSD)

    Change from Baseline to Week 4, Week 8, 3 month follow up, 6 month follow up

  • Total Sleep Time Measured by The Consensus Sleep Diary (CSD):

    Change from Baseline to Week 4, Week 8, 3 month follow up, 6 month follow up

Study Arms (2)

Cognitive Behaviour Therapy for Insomnia (CBT-I)

EXPERIMENTAL

Participants will receive individualized CBT-I delivered by video-conferencing over the course of eight weeks.

Behavioral: Cognitive Behaviour Therapy for Insomnia (CBT-I)

Waitlist Control Group

EXPERIMENTAL

Participants in the waitlist control group will be required to monitor their sleep with sleep diaries for 7 weeks. They will receive CBT-I delivered by video-conferencing immediately after the waiting period.

Behavioral: Cognitive Behaviour Therapy for Insomnia (CBT-I)

Interventions

CBT-I is a manualized multi-component intervention that includes sleep restriction, stimulus control, cognitive restructuring, relaxation training, and sleep hygiene.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Men and women who are easily able to understand and read English
  • No current evidence of cancer or clinically stable/inactive disease
  • Received and completed all adjuvant treatments at least 6 months prior to study entry to allow for neural stabilization and recovery
  • Self-reported PCI as indicated by a score of "sometimes" or higher ("quite a lot" or "always") on at least two out of three questions that assess memory, concentration, and attention
  • Meet the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria for insomnia disorder and have a score of 8 or greater on the Insomnia Severity Index (ISI)
  • Have good performance status as indicated by an Eastern Cooperative Oncology Group (ECOG) score of 0-2
  • Have high-speed internet connection, webcam, and are fluent using the internet
  • Men and women who are easily able to understand and read English
  • A diagnosis of a hematological malignancy currently in remission
  • Completed cancer treatments including transplant, chemotherapy and/or immunotherapy at least 6 months prior to study entry
  • Self-reported PCI as indicated by a score of "sometimes" or higher ("quite a lot" or "always") on at least two out of three questions that assess memory, concentration, and attention
  • Meet the DSM-5 criteria for insomnia disorder and have a score of 8 or greater on the Insomnia Severity Index
  • Have good performance status as indicated by an ECOG score of 0-2
  • Have high-speed internet connection, webcam, and are fluent using the internet

You may not qualify if:

  • Another sleep disorder, besides insomnia, that is not adequately treated (ie: untreated obstructive sleep apnea)
  • The presence of another psychological disorder that is not currently stable and/or would impair the ability to participate in the study
  • A major sensory deficit (e.g. blindness)
  • A neurologic or major medical condition known to affect cognitive function (e.g., Parkinson's)
  • A history of cranial radiation
  • A history of any other condition that may affect cognitive functioning (e.g., traumatic brain injury)
  • Previous experience with CBT-I
  • Other considerations:
  • Participants will not be excluded for using psychotropic medication prior to study entry (e.g. antidepressants) provided that the dose was not recently altered (stable over the previous 6 weeks)
  • Considering the potential for prescription of medications to help with sleep (e.g. hypnotics, sedatives, and antidepressants) within the cancer population, medication use throughout the study will be tracked and adjusted for in the statistical analysis

Limitations and Caveats

Clinical trials using a waitlist condition generally inflate treatment effects; Use of waitlist control precluded comparing groups on long-term outcomes; Close to half of the patients in this trial were long-term cancer survivors, which may reduce the ability to attribute their functioning to their cancer diagnosis or treatments; The improvements observed in cancer-related cognitive impairment are only generalizable to patients who have insomnia and cognitive impairment.
