- Brief Summary
This randomized phase II trial studies how well brief behavioral therapy works in improving sleep disorders in patients with stage I-III breast cancer undergoing chemotherapy. Sleep disorder counseling may reduce fatigue and insomnia as well as improve the well-being and quality of life in patients with breast cancer who are undergoing chemotherapy.
- Detailed Description
PRIMARY OBJECTIVES:
I. Determine recruitment rates to the proposed randomized controlled trial (RCT).
II. Determine the rate of intervention adherence. III. Determine the feasibility of training National Cancer Institute (NCI) Community Oncology Research Program (NCORP) clinical research staff to successfully deliver the Brief Behavioral Therapy (BBT) intervention.
SECONDARY OBJECTIVES:
I. Obtain preliminary estimates for the effect of the intervention (compared with control) on insomnia as measured by the Insomnia Severity Index (ISI).
II. Obtain preliminary estimates for the effect of the intervention (compared with control) on sleep quality as measured by the Pittsburgh Sleep Quality Index (PSQI).
III. Obtain preliminary estimates for the effect of the intervention (compared with control) on circadian rhythm as measured by the two-oscillator cosinor parameter estimates based on actigraphy data.
IV. Obtain preliminary estimates for the effect of the intervention (compared with control) on heart rate variability (HRV) as measured by the Firstbeat® ambulatory heart-rate monitor (i.e., 1. respiratory sinus arrhythmia-RSA, 2. standard deviation of all normal R-wave to R-wave intervals--SDNN, 3. root mean square of successive differences between adjacent normal R-wave to R-wave intervals--RMSSD, 4. The ratio of low frequency total spectrum power of all NN intervals between .04 to .15 Hertz to high frequency total spectrum power of all NN intervals between .15 to .40 Hertz--LF/HF ratio, and 5. natural log of low frequency total spectrum power of all NN intervals between 0.04 to 0.15Hz.).
TERTIARY OBJECTIVES:
I. Obtain preliminary estimates for the effect of the intervention (compared with control) on quality of life as measured by the Functional Assessment of Chronic Illness Therapy (FACIT) total score and subscales.
II. Obtain preliminary estimates for the effect of the intervention (compared with control) on general mood as measured by the Profile of Mood States (POMS) total score and subscales.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients undergo BBT intervention, comprising insomnia education, stimulus control, discouragement of napping and encouragement of exercise, and sleep compression over two 60 minute face-to-face sessions in weeks 1 and 3 or 4, and four 15 minute telephone sessions in weeks 2, 3, 5, and 6 or 2, 4, 5, and 6.
ARM II: Patients undergo Healthy Eating Education (HEAL) comprising nutritional education and suggestions for symptom management over two 60 minute face-to-face sessions in weeks 1 and 2 or 3, and four 15 minute telephone sessions in weeks 2, 3, 5, and 6 or 2, 4, 5, and 6.
After completion of study, patients are followed up at 1 month.

Group Intervention Description Arm II (control) Telephone-Based Intervention Patients undergo HEAL comprising nutritional education and suggestions for symptom management over two 60 minute face-to-face sessions in weeks 1 and 3 or 4, and four 15 minute telephone sessions in weeks 2, 3, 5, and 6 or 2, 4, 5, and 6. Arm I (BBT intervention) Telephone-Based Intervention Patients undergo BBT intervention, comprising insomnia education, stimulus control, discouragement of napping and encouragement of exercise, and sleep compression over two 60 minute face-to-face sessions in weeks 1 and 3 or 4, and four 15 minute telephone sessions in weeks 2, 3, 5, and 6 or 2, 4, 5, and 6. Arm II (control) Educational Intervention Patients undergo HEAL comprising nutritional education and suggestions for symptom management over two 60 minute face-to-face sessions in weeks 1 and 3 or 4, and four 15 minute telephone sessions in weeks 2, 3, 5, and 6 or 2, 4, 5, and 6. Arm I (BBT intervention) Brief Behavioral Therapy Patients undergo BBT intervention, comprising insomnia education, stimulus control, discouragement of napping and encouragement of exercise, and sleep compression over two 60 minute face-to-face sessions in weeks 1 and 3 or 4, and four 15 minute telephone sessions in weeks 2, 3, 5, and 6 or 2, 4, 5, and 6.
- Primary Outcome Measures
Name Time Method Percentage of Key Components of BBT Delivered by NCI Community Oncology Research Program (NCORP) Staff, Assessed by Checklist and Auditing of Audio-recordings Up to 1 month Each NCORP staff person completed a study checklist in which they designated which concepts they discussed with the patient at each session. Concepts included how sleep problems develped, how to control stimulus, and sleeping environment. The overall mean percent delivery was measured using a random effects model (residual maximum likelihood \[REML\] estimation), where the intercept represents the mean delivery and three independent random effects are included. Because of the small sample size, testing will use the Kenward-Roger procedure.
Percentage of Eligible Patients Consented baseline Will be evaluated by calculating the specific percentage (with 95% confidence interval) of the total number of participants approached that then consented and enrolled in the study.
Percentage of Consented Participants Who Complete the Study, Defined as Completion of at Least 5 BBT Up to 1 month Will be evaluated by calculating the specific percentage (with 95% confidence interval) and performing an exact binomial test with the null hypothesis being greater than or equal to 75%.
- Secondary Outcome Measures
Name Time Method Change in Circadian Rhythm Amplitude Over 12 Hours baseline to up to 1 month Activity levels were measured using an actigraphy device worn as a watch. The data was collected by the device for a 24 hour period. A model consisting of two cosine functions, one with a period of 12 hours, and the other with a period of 24 hours is fit to log activity counts as the dependent variable, and hour (0 to 24) as the independent variable. The amplitude is the highest activity level over a 12 hour period.
Change in Mean Circadian Rhythm Acrophase Over 24 Hours baseline to up to 1 month Activity levels were measured using an actigraphy device worn as a watch. The data was collected by the device for a 24 hour period. A model consisting of two cosine functions, one with a period of 12 hours, and the other with a period of 24 hours is fit to log activity counts as the dependent variable, and hour (0 to 24) as the independent variable. The acrophase is the time where peak activity occurs over a 24 hour period. The larger the acrophase the later in the day is the peak activity.

The acrophase is the time where peak activity occurs over a 12 hour period. The larger the acrophase the later in the day is the peak activity.
Change in Insomnia as Measured by the Insomnia Severity Index (ISI) Baseline to up to 1 month The ISI has seven questions. The seven answers are added up to get a total score.
Total score categories:
0-7 = No clinically significant insomnia 8-14 = Subthreshold insomnia 15-21 = Clinical insomnia (moderate severity) 22-28 = Clinical insomnia (severe) The difference between arms will be assessed using analysis of covariance (ANCOVA). The response will be the post-intervention outcome. Arm will be the factor, and baseline will be the covariate. Appropriate contrasts will be used to estimate the difference between arms in change from baseline. Initially, the arm\*baseline interaction will be assessed with an F test. If this interaction is insignificant at the 0.05 level, it will be dropped from the final model. If the interaction is significant, then mean change from baseline at various levels of baseline will be reported.Change in Sleep Quality as Measured by the Pittsburgh Sleep Quality Index (PSQI) Baseline to up to 1 month Each item is weighted on a 0-3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality. The difference between arms will be assessed using ANCOVA. The response will be the post-intervention outcome. Arm will be the factor, and baseline will be the covariate. Appropriate contrasts will be used to estimate the difference between arms in change from baseline. Initially, the arm\*baseline interaction will be assessed with an F test. If this interaction is insignificant at the 0.05 level, it will be dropped from the final model. If the interaction is significant, then mean change from baseline at various levels of baseline will be reported.
Change in Circadian Rhythm Amplitude Over 24 Hours baseline to up to 1 month Activity levels were measured using an actigraphy device worn as a watch. The data was collected by the device for a 24 hour period. A model consisting of two cosine functions, one with a period of 12 hours, and the other with a period of 24 hours is fit to log activity counts as the dependent variable, and hour (0 to 24) as the independent variable. The ampliitude is the peak activity level over a 24 hour period.
Change in Mean Circadian Rhythm Mesor Baseline to up to 1 month Activity levels were measured using an actigraphy device worn as a watch. The data was collected by the device for a 24 hour period. A model consisting of two cosine functions, one with a period of 12 hours, and the other with a period of 24 hours is fit to log activity counts as the dependent variable, and hour (0 to 24) as the independent variable. The mesor is the average activity over a 24 hour period.
