Lung cancer is a malignant tumor that has transformed from a single cancer disease into one of the most striking global health problems. Lung cancer has an insidious onset, and most patients are first diagnosed with the middle and advanced stage. Cancer related fatigue is the most common and distressing symptom reported by lung cancer patients. For cancer patients, fatigue has lasting impact on physical, psychological and social functions, interferes with activities and participating in life events, thereby worsening the health-related quality of life. Acceptance and Commitment Therapy (ACT) is the third-wave cognitive behavioral therapy to improve functioning and health-related quality of life by increasing psychological flexibility. The study aims to examine the effectiveness of ACT on fatigue interference and health-related quality of life in patients with advanced lung cancer.
A two-arm, assessor-blind randomized controlled trial will be conducted to investigate the effects of ACT on advanced lung cancer patients compared to usual care. Participants in the same ward will be randomized at a 1:1 ratio to the intervention group or control group. Block randomization will be conducted by an independent research assistant using randomly varying block size of 4, 6 to avoid selection bias. The study aims to examine the effectiveness of ACT on fatigue interference and health-related quality of life in patients with advanced lung cancer. The Specific objectives are: 1) To investigate the effects of ACT on primary outcomes: fatigue interference and health-related quality of life compared to control group at post-intervention and three months follow-up. 2) To investigate the effects of ACT on the secondary outcomes: cancer-related fatigue, depressive symptoms, anxiety, distress and exercise capacity and process outcomes including psychological flexibility, ACT related variables (acceptance and cognitive defusion) at post-intervention and three months follow-up.

| Acceptance and Commitment Therapy (ACT) | Behavioral | Session 1: This session aims to let the participants get familiar with the interventionist. The interventionist will tell them the purpose of the program and basic rules. And the interventionist will promise their privacy protection. Session 2: This session includes how to separate thoughts/feelings/sensations related to diagnose with advanced lung cancer and experience of fatigue with facts and see these feelings in an objective way with observing self. Session 3: This session mainly aims to help participants understand the importance of values, differentiate values from goals and clarify their personal values. Session 4: This session aims at helping patients practice to engaging in committed action based on chosen values, motivated to change behavior in consistency with life direction and health goal. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in the score of fatigue interference assessed by The Fatigue Symptom Inventory at one week after the intervention | A 13-item instrument that measures the intensity and interference of fatigue over the previous 7 days. The first four items are used to assess the intensity of fatigue, Item 5 - Item 11 are to assess the degree to which fatigue in the past week was judged to interfere with different aspects, such as general activity, bathe and dress ability, work activity, concentration ability, relation with others, enjoyment of life and mood, using a 11-point Likert scale ranging from 0 (no interference) to 10 (extreme interference). 0 indicates no fatigue and 127 indicates the worst fatigue intensity and interference. Change= (One week after the intervention score - Baseline score) | Baseline (T0) and post-intervention (T1, one week after the 4-week intervention) |
| Change from baseline in the score of the score of fatigue interference assessed by The Fatigue Symptom Inventory at three months after the 4-week intervention | A 13-item instrument that measures the intensity and interference of fatigue over the previous 7 days. The first four items are used to assess the intensity of fatigue, Item 5 - Item 11 are to assess the degree to which fatigue in the past week was judged to interfere with different aspects, such as general activity, bathe and dress ability, work activity, concentration ability, relation with others, enjoyment of life and mood, using a 11-point Likert scale ranging from 0 (no interference) to 10 (extreme interference). 0 indicates no fatigue and 127 indicates the worst fatigue intensity and interference. Change= (Three months after the intervention score - Baseline score) | Baseline (T0) and three months follow-up (T2, three months after the 4-week intervention) |

The overall score can be obtained by adding all subscale scores. 0 indicates no quality of life and 144 indicates the highest quality of life. Change= (One week after the intervention score - Baseline score) |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in the score of cancer related fatigue assessed by The Multidimensional Fatigue Inventory at one week after the intervention | 20-item self-reported instrument testing the subjective experience of fatigue. 20 indicates the low level of fatigue and 80 indicates the high level of fatigue. 20 indicates low level of fatigue and 80 indicates the high level of fatigue.
