This study evaluates the effectiveness of a coping skills and exercise (CSTEX) intervention among post lung transplant patients aimed to reduce distress and improve functional capacity. Half of the patients will receive CSTEX and half will receive the standard of care plus transplant education (SOC-ED).
The study will aim to evaluate the effectiveness of the CSTEX intervention in (i) reducing distress and (ii) improving functional capacity. It is hypothesized that compared to SOC-ED, the CSTEX intervention will result in 1) greater reductions in global distress measured by an established psychometric test battery; and 2) greater improvements in functional capacity assessed by distance walked on a standard Six Minute Walk test (6MWT).

The CSTEX condition has two integrated components: the CST component will systematically train patients in the use of coping skills for stress reduction and promote key transplant-specific health behaviors. The exercise component of the intervention will progressively increase participants exercise and promote daily physical activity through motivational interviewing strategies.
The SOC-ED condition provides support and enhanced post-transplant education. Participants will be given detailed educational information about post-transplant care, the importance of medication adherence, and maintenance of physical activity.

Change in Global Psychological Distress
A composite distress score will assess change from baseline to 12 weeks (post-intervention) and combine the following instruments: General Health Questionnaire, Perceived Stress Scale, Beck Depression Inventory-II, State Trait Anxiety Inventory, and PROMIS Anger. The composite distress score is the average of the participant's rank for change (from baseline to 12 weeks) on each of the 5 scales. A lower rank represents more improvement (decrease in global distress) and higher ranks represent less improvement (or worsening of distress). Scoring is based on the number of participants analyzed; in this case the possible score range is 1-180. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Functional Capacity
Functional capacity will be measured by distance walked on a standard Six Minute Walk Test (6MWT) at baseline and again post-intervention at 12 weeks. Distance measured in feet. Greater distance represents better functional capacity. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Physical Activity
Daily physical activity (average steps per day) will be assessed via a wrist-worn activity monitor (Actigraph GT9X Link) for 7 consecutive days at baseline and again post-intervention at 12 weeks. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Sleep Quality
Sleep quality (average total minutes of sleep per night) will be assessed via the Pittsburgh Sleep Quality Index at baseline and again post-intervention at 12 weeks. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Quality of Life

Quality of Life will be assessed via the Lung Transplant Quality of Life Survey, which is comprised of 10 scales that measure symptoms, health perceptions, functioning, and well being at baseline and again post-intervention at 12 weeks. The QOL overall score ranges from 1 to 5, with a higher score indicating worse health. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Frailty
Frailty will be measured by performance on the Fried Frailty Index. This assessment includes measures on patient's weight, exhaustion level, physical activity, walking speed, and hand grip strength at baseline and again post-intervention at 12 weeks. Scores range from 0 to 5, with lower scores indicating less frailty. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Problem-Focused Coping
Coping was assessed via the Brief COPE Inventory, which is composed of scales that measure problem-focused coping, emotion-focused coping, and avoidant coping responses at baseline and again post-intervention at 12 weeks. Items are scored on a 4-point Likert scale, with 1 indicating a coping mechanism that the participant has not been doing at all, to 4 indicating a coping mechanism in which the participant has been doing a lot. A higher average score within the problem-focused subscale indicates better coping strategies. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Emotion-Focused Coping
Coping was assessed via the Brief COPE Inventory, which is composed of scales that measure problem-focused coping, emotion-focused coping, and avoidant coping responses at baseline and again post-intervention at 12 weeks. Items are scored on a 4-point Likert scale, with 1 indicating a coping mechanism that the participant has not been doing at all, to 4 indicating a coping mechanism in which the participant has been doing a lot. A higher score within the emotion-focused coping subscale indicates better coping strategies. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Avoidant Coping
Coping was assessed via the Brief COPE Inventory, which is composed of scales that measure problem-focused coping, emotion-focused coping, and avoidant coping responses at baseline and again post-intervention at 12 weeks. Items are scored on a 4-point Likert scale, with 1 indicating a coping mechanism that the participant has not been doing at all, to 4 indicating a coping mechanism in which the participant has been doing a lot. A lower score within the avoidant coping subscale indicates a more useful coping strategy. The change value is calculated as T2 (12 weeks) - T1 (baseline).
Time frame: Baseline to 12 weeks
Change in Self-Efficacy
Self-efficacy will be assessed via the General Self-Efficacy Scale, which is a 10-item scale that measures emotional distress at baseline and again post-intervention at 12 weeks. Scores range from 10-40 with a higher score indicating better self-efficacy. The change value is calculated as T2 (12 weeks) - T1 (baseline).
