Managing psychological and physical symptoms to improve quality of life in patients with lung cancer are a major public health concern. Mindfulness-based therapies are showing promise in modifying psychological distress and improving quality of life in some cancer groups, but little testing has included lung cancer samples. Mindfulness-based therapies integrate meditation, breathing, and gentle yoga practices to promote an attitude of nonjudgmental acceptance and awareness of bodily states. Such strategies may promote well being, self-regulation, and symptom management. The study purpose was to test the acceptability, feasibility, and symptom / health-related quality of life (HRQOL) outcomes of a home-based mindfulness intervention for individuals with advanced lung cancer during non-curative treatment (radiation and/or chemotherapy). Acceptability and feasibility were measured via patient consent and retention rates, therapy expectancy, study adherence, attrition reasons, and quality assurance indicators. Efficacy was determined via symptom and HRQOL (health perceptions, physical and emotional function) outcomes. 40 patients undergoing treatment of non-small cell lung cancer were randomized to receive either six weekly mindfulness sessions (N=20) or an attention control condition (N=20). Outcome data was obtained at baseline (Time 1), post-intervention (Time 2, week 8), and four weeks after completion (Time 3, week 11). In addition, both groups received weekly symptom assessment interviews. The hypothesis was that the mindfulness group would report better symptom management and HRQOL (lower worry, dyspnea, insomnia, depression; higher physical and social function; more positive health perceptions) than the attention control group at the protocol end and that these differences will be sustained at Time 3.
The final sample (n = 32) included 16 patients in the intervention and 16 in the attention control group (study attrition (n = 8, 20%).
7,243 studies on the registry are indexed under Lung Neoplasms; 1,558 are open to participants now.

M.D. Anderson Symptom Inventory (MDASI)
Symptom Severity and interference were measured with the M.D. Anderson Symptom Inventory (MDASI) . The MDASI is a multisymptom patient-reported outcome measure. The MDASI has 13 core items include symptoms found to have the highest frequency and/or severity in patients with various cancers and treatment types (pain, fatigue, nausea, vomiting, disturbed sleep, distress, shortness of breath, memory difficulties, lack of appetite, drowsiness, dry mouth, sadness,numbness and tingling. Patients rate the severity of each symptom "at its worst" using 0-10 numerical rating scales with 0 = "not present" and 10 = "as bad as you can imagine." The measure includes 5 symptom interference items which ask how much all symptoms, interfere with domains (walking, work, general activity, mood, relations with others, enjoyment of life) also rated on a 0-10 scale (0 = "did not interfere"; 10 = "interfered completely"). The 13 severity (range 0 - 130) and 5 interference items (range 0 - 50) are summed.
Time frame: Time 2 (week 8), Time 3 (week 11), and overall average for group comparisons.
SF-36
Health-related Quality of Life (HRQOL) Indices (Physical/Emotional Function, Role Function, Pain, General Health, Vitality, Mental/Physical Health)HRQOL(SF-36) calculated using Quality Metric, Inc. an algorithm producing normal scores (1-100 range). With normed scoring, general population has mean=50, SD=10. For the minimum and maximum values in each of the scale ranges provided, higher values represent a better outcome.
Time frame: Time 2 (week 8), Time 3 (week 11), and overall average for group comparisons.
Center for Epidemiologic Studies Depression (CES-D)
The score is the sum of the 20 questions. Each item has a range of 1 - 4 for frequency of a behavior or mental state in the past week ; 1 - Rarely or none of the time (less than 1 day); 2 = Some or a little of the time (1-2 days); 3 = Occasionally or a moderate amount of time (3-4 days); 4 = Most or all of the time (5-7 days). Possible range is 0-60. There are 4 reverse-scored items (questions 4, 8, 12, and 16). A score of 16 points or more is considered depressed.
Time frame: Time 2 (week 8), Time 3 (week 11), and overall average for group comparisons.
Cancer Dyspnea Scale
The cancer dyspnea scale (CDS) has 12 Likert scale items ( 1 = Not at all, 5 = Very much) that ask questions about breathlessness or difficulty in breathing during the past few days. The CDS has an overall score (range 0-42) and 3 subscales that measure the amount of effort with breathing, anxiety associated with breathing, and discomfort associated with breathing. The 3 subscales are calculated by: 1) effort (items 4+6+8+10+12) - 5 \[range 0 (no dyspnea effort)-20 (worst dyspnea effort)\]; 2) anxiety (items 5+7+9+11) - 4 \[range 0 (no dyspnea anxiety) - 16 (worst dyspnea anxiety)\]; 3) discomfort \[15 - (items 1+2+3) {range 0 (no dyspnea discomfort) - 12 (worst dyspnea discomfort)}\]. The total dyspnea score is derived by adding the total subscale scores. The subscale score subtractions are to make adjustments for 0 as a state of absence of dyspnea (thus total dyspnea summary scores range from 0 to 42).
Time frame: Time 2 (week 8), Time 3 (week 11), and overall average for group comparisons.
Worry (Cancer-related and General)
Both cancer-related and general worry were measured with 3 item scales. Cancer-related worry had three statements asking about level of worry related to diagnosis, treatment, and worry interference using a 1 = "not at all" to 5 = "most or all the time" scale, range 3-15. Items are summed. General worry used an abbreviated brief Penn State Worry questionnaire with 3 statements that measure how typical that statements are in describing the person. Uses a 3 item scale with 1 = "not at all typical" to 5 = "very typical". the range is 3-15. Items are summed.
Time frame: Time 2 (week 8), Time 3 (week 11), and overall average for group comparisons.
Pittsburgh Sleep Symptom Questionnaire-Insomnia (PSSQ_I)
The PSSQ_I has 13 self rated questions. The first 5 items, used to determine sleep quality (presence; frequency of insomnia problems) are rated \[0 = never to 5 = always, 5-7 days per week; (range 0-25)\] and items 6 to 13 are aimed at identifying the degree of interference experienced from sleep impairment (rated 0=not at all to 4=extremely on Likert scale; range 0 - 32).
Time frame: Time 2 (week 8), Time 3 (week 11), and overall average for group comparisons.
