Brief Behavioral Intervention for Insomnia During Chemotherapy

The effects of the Brief Behavioral Therapy for Insomnia (BBT-I) intervention on insomnia will be measured by the Insomnia Severity Index (ISI). The ISI survey questionnaire is a 7-question survey, with each question having 5 possible answers (none, mild, moderate, severe, or very severe), scored as 0, 1, 2, 3, or 4, respectively. The full range of ISI scores is from 0 to 28. Lower scores are considered good, better, or healthy, and increasingly higher scores are considered to indicate greater insomnia. Clinical interpretation is as follows:

• 0 to 7 = No clinically significant insomnia
• 8 to14 = Sub-threshold insomnia (mild)
• 15 to 21 = Clinical insomnia (moderate severity)
• 22 to 28 = Clinical insomnia (severe) ISI survey will be conducted at baseline, post intervention, 6 months and 12 months. The outcome is reported as the mean ISI score at baseline; immediately post-intervention (6 weeks nominal); 6 months; and 12 months.

The Brief Fatigue Inventory (BFI) survey questionnaire is a 9-question survey, with each question having 11 possible answers ("No fatigue" to "As bad as you can imagine"), scored from 0 to 10, with the total score being the sum of a participant's individual questions scores at a timepoint and will range from 0 to 90. Lower scores are considered good, better, or healthy, and increasingly higher scores are considered to indicate greater fatigue.

The BFI survey was conducted at baseline, post intervention, 6 months, and 12 months. The outcome is reported as the mean of the overall BFI scores with standard deviation at baseline, immediately post-intervention (6 weeks nominal), 6 months, and 12 months.

Anxiety and depression will be assessed by administration of the Clinical Assessment of Depression (CAD). The CAD questionnaire is a 50-item survey, with each statement having 4 possible responses ("Strongly Disagree" to "Strongly Agree"), scored from 1 to 4, The raw scores are then converted to T-scores. A score of 50 represents the mean. A difference of 10 from the mean in either the positive or negative direction indicates a difference of one standard deviation.

The CAD survey was conducted at baseline, post intervention, 6 months, and 12 months. The outcome is reported as the mean of the overall CAD scores with standard deviation at baseline, immediately post-intervention (6 weeks nominal), 6 months, and 12 months.

Neuropsychological assessments will be conducted using the Comprehensive Trail Making Test (CTMT), an assessment of simple attention and executive function, consisting of 5 dot-to-dot exercises that increase with complexity and difficulty. A score of 50 represents the mean. A difference of 10 from the mean in either the positive or negative direction indicates a difference of one standard deviation. Thus, a score of 60 is one standard deviation above the mean, while a score of 30 is two standard deviations below the mean. Overall, higher values indicate better executive functioning, attention, and processing speed.

The CTMT assessment was conducted at baseline, post intervention, 6 months, and 12 months. The outcome is reported as the mean of the overall CTMT scores with standard deviation at baseline, immediately post-intervention (6 weeks nominal), 6 months, and 12 months.

Neuropsychological assessments will be conducted using the Delayed Recall sub-test from the overall Hopkins Verbal Learning Test Revised (HVLT-R). The result values are known as the T score. A higher T scores indicating better memory (recall).A score of 50 represents the mean. A difference of 10 from the mean in either the positive or negative direction indicates a difference of one standard deviation

The HVLT-R sub-test assessment for Delayed Recall was conducted at baseline, post intervention, 6 months, and 12 months. The outcome is reported as the mean score with standard deviation at baseline, immediately post-intervention (6 weeks nominal), 6 months, and 12 months.

Neuropsychological assessments will be conducted using the Verbal Learning and Memory sub-test from the overall Hopkins Verbal Learning Test Revised (HVLT-R). The result values are known as the T score.The higher T scores indicating better memory (recall). A score of 50 represents the mean. A difference of 10 from the mean in either the positive or negative direction indicates a difference of one standard deviation

The HVLT-R sub-test assessment for Verbal Learning and Memory was conducted at baseline, post intervention, 6 months, and 12 months. The outcome is reported as the mean score with standard deviation at baseline, immediately post-intervention (6 weeks nominal), 6 months, and 12 months.

Neuropsychological assessments will be conducted using the Controlled Oral Word Association Test (COWAT), a verbal fluency task that assesses complex cognition. The test value is the the count of words that meet pre-defined criteria within 1 minute, so the minimum is 0 and no fixed maximum exists. Adjustments are made to the raw score based on participant age and education level, resulting in a scaled score. Higher scores reflect a better outcome, meaning better cognition and verbal fluency.

The COWAT assessment was conducted at baseline, post intervention, 6 months, and 12 months. The outcome is reported as the mean of the COWAT score with standard deviation at baseline, immediately post-intervention (6 weeks nominal), 6 months, and 12 months.

Cognitive difficulties will be assessed by administration of the Mobile Cognitive Assessment Battery (MCAB), comprised of 3 neuropsychological tests and a self-reported assessment. MCAB measures cognitive flexibility, accuracy, processing speed, working memory and multitasking.

The MCAB survey was to be conducted at baseline, post intervention, 6 months, and 12 months. The outcome was to be reported as the mean of the overall MCAB scores with standard deviation at baseline, immediately post-intervention (6 weeks nominal), 6 months, and 12 months.
