OBJECTIVES
- To assess feasibility (accrual, participation, adherence, retention) of a randomized study of device-guided breathing and music in 75 post-treatment lung cancer survivors with significant anxiety.
- To obtain preliminary data on the variability and efficacy of two doses of a device-guided breathing intervention versus a music control group for reducing anxiety (primary outcome) and for improving self-reported dyspnea and respiratory functioning (secondary outcomes) in post-treatment lung cancer survivors.
- To select the optimal dose of the device-guided breathing intervention (15 minutes once/day or twice/day) for subsequent randomized study.

- Retention - Number of Participants Who Complete the Final Assessment [ Time Frame: 12 weeks ]Retention will be calculated as the number of participants who complete the final assessment divided by number randomized.
- Adherence- Amount of Time the Device is Used [ Time Frame: 12 weeks ]Adherence will be calculated as the actual amount of time the device is used divided by the prescribed time. Successful adherence will be defined as use of the device ≥80% of the time assigned.
- Accrual Rate- Number of Patients Accrued to the Study [ Time Frame: Time from study opening to study close ~46.42 months ]The accrual rate will be calculated as the number of patients accrued to the study divided by the number of months of accrual.
- Change From Baseline for Anxiety as Measured by Hospital Anxiety and Depression Scale (HADS) [ Time Frame: 12 weeks ]To obtain preliminary data on the variability and efficacy of two doses of a device-guided breathing intervention versus a usual breathing control group for reducing anxiety. This is a 14-item self-report measure of cognitive and behavioral symptoms of anxiety and depression; clinically significant symptoms are indicated by a score of greater than or equal to 8 with a range from 0 to 42. Higher scores indicate more anxiety.
- Salivary Cortisol Levels [ Time Frame: 12 weeks ]Cortisol levels will be assessed upon awakening, 30 minutes post-awakening, and at bedtime for three consecutive days at baseline and three consecutive days.
- DNA Methylation Levels [ Time Frame: 12 weeks ]DNA methylation levels will be measured To determine if changes in anxiety are associated with methylation
- Gene Expression Levels [ Time Frame: 12 weeks ]The DNA methylation and gene expression patterns between the different groups.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Past History of any lung cancer
- For Stage I-III disease, patients should be 2-24 months post-completion of surgery, radiation therapy and/or chemotherapy with no further planned treatment during the 12-week study and no evidence of disease.
- For Stage IV disease, patients may be receiving no treatment or may be receiving maintenance treatment with a target agent, chemotherapy, or immunotherapy provided the most recent imaging does not demonstrate progressive disease.
- After completion of all three screening questionnaires, participant must score accordingly on at least one questionnaire to be eligible.
- Willing/able to attend brief introductory session and use assigned device for the assigned period of time (15 minutes once or twice per day), at least 5 days per week for 12 weeks
- Age ≥ 18 years
- Must have telephone
Exclusion Criteria:
- Patient does not understand English
- Active lung infection
- Progressive cancer (must be considered no evidence of disease or stable)
- Any change in psychotropic medications in past 30 days
- Hearing loss that would preclude participating in interventions. Adequate hearing to participate will be determined via: (1) Response of "no" to the question ["Do you have a hearing problem now?"] Participants with hearing aids will be allowed to enroll as long as their hearing is adequate to hear the sounds on the study devices. If necessary, potential study participants will receive a brief test trial with the RESPeRATE device. If they indicate inability to hear the guiding tones, they will not be enrolled in the study.
Cortisol Exclusion
- Participants with endocrine disorders (e.g., diabetes and thyroid disorders) or on steroid-based medications are excluded from the cortisol portion of the study (with the exception of topical hydrocortisone that is permitted).
