Acceptance and Commitment Therapy on Fatigue Interference in Patients With Advanced Lung Cancer and Caregiver Burden (ACT)

Effects of Acceptance and Commitment Therapy on Fatigue Interference in Patients With Advanced Lung Cancer and Caregiver Burden: A Pilot Randomised Controlled Trial

Lung cancer is a malignant tumour 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 stages. Cancer-related fatigue is the most common and distressing symptom reported by lung cancer patients. For cancer patients, fatigue has a lasting impact on physical, psychological and social functions, and interferes with activities and participating in life events, thereby worsening the health-related quality of life. Family members have a key role in providing advanced lung cancer patients with informational, instrumental, and emotional support, which is crucial to patients' adaptation to the advanced illness and living a meaningful cancer life. Acceptance and Commitment Therapy (ACT) is the third-wave cognitive behavioural therapy to improve functioning and health-related quality of life by increasing psychological flexibility. The study aims to examine test the feasibility and acceptability, and preliminary effects of online ACT on fatigue interference in patients with advanced lung cancer and caregiver burden.

Study Overview

• Status: Not yet recruiting
• Conditions: Lung Cancer; Caregiver Burden; Advanced Cancer
• Intervention / Treatment: Behavioral: Acceptance and Commitment Therapy (ACT) plus health education; Other: Health education

Detailed Description

A two-arm, assessor-blind randomised controlled trial will be conducted to investigate the effects of ACT on advanced lung cancer patients and caregivers compared to educational control. Participants in the same ward will be randomised 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 sizes of 4 and 6 to avoid selection bias. The study aims to examine the feasibility and acceptability, and preliminary effects of online ACT on fatigue interference in patients with advanced lung cancer and caregiver burden. The Specific objectives are:

1. To investigate the feasibility and acceptability of the online 6-week ACT in patients with advanced lung cancer and caregivers in rural areas in China;
2. To investigate the preliminary effects of the online 6-week ACT in patients with advanced lung cancer and caregivers in rural areas in China;
3. To explore how patients and caregivers perceive the ACT experience during the intervention process.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: ACT group; Participants in the intervention group will receive ACT intervention, consisting of six online sessions via video conferencing platform (The first two sessions for patient only, the third and fourth sessions for caregiver only, and the last two sessions for patient-caregiver dyads) of 60-90 min each (once/week), in addition to health education.	Behavioral: Acceptance and Commitment Therapy (ACT) plus health education; Session 1: Reviewing experiences on struggles with CRF, realising consequence of controlling, introducing acceptance as an alternative, adopting virtual mindfulness. Education (patient): epidemiologic features of advanced lung cancer. Session 2: Separate thoughts/feelings related to CRF. Education (patient): treatments and symptoms of advanced lung cancer. Session 3: Reviewing caregiver's experiences of struggling with caregiving burden,introducing acceptance as an alternative. Education (caregiver): epidemiologic features of advanced lung cancer. Session 4: Separate caregivers' thoughts/feelings related to caregiving burden. Education (caregiver): treatments and symptoms of advanced lung cancer. Session 5:Understand the importance of values and clarifying personal values for dyads. Education (dyads): eating suggestions. Session 6: Emphasise ongoing value-based goals and commitment to actions for a meaningful cancer life for dyads. Education (dyads): exercising suggestions.
Other: Health eduction control group; Participants randomised to the health education control group will receive six weekly health education by a video-conferencing platform. The topics mainly include treatments and daily care during admission, medication instructions and side effects, diet and exercise advice, and retest recommendations when discharged.	Other: Health education; Session 1: health education on the epidemiologic features of advanced lung cancer will be taught to patients. Session 2: health education on treatments and related symptoms of advanced lung cancer will be taught to patients. Session 3: health education on the epidemiologic features of advanced lung cancer will be taught to caregivers. Session 4: health education on treatments and related symptoms of advanced lung cancer will be taught to caregivers. Session 5: health education on eating suggestions for advanced lung cancer patients and caregivers will be taught. Session 6: health education on exercising suggestions for advanced lung cancer patients and caregivers will be taught.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Eligibility rate	The eligiblity rate is defined as the percentage of participants fulfilling the inclusion criteria amongst the participants screened for the eligibility	Before baseline
Recruimtment rate	The recruitment rate is defined as the percentage of participants who consented to participate in the study amongst the participants eligible for the study	Before baseline
Attrition rate	The attrition rate is defined as the percentage of participants who withdrew from the study before completion	After the 6-week intervention
Adherence rate	The adherence rate is defined as the frequency of the practice of mindfulness and session attendance	After the 6-week intervention
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.	Baseline (T0) and post-intervention (T1, one week after the 6-week intervention)
Change from baseline in the score of caregiver burden assessed by The Zarit Caregiver Burden Inventory at one week after the intervention	12 items score from 1(not always) to 5 (always) to assess caregiver burdens of caregivers of advanced lung cancer patients, including three domains: role strain, self-criticism, and negative emotion. The overall score can be obtained by adding all subscale scores. 12 indicates low caregiver burden and 60 indicates the highest caregiver burden.	Baseline (T0) and post-intervention (T1, one week after the 6-week intervention)
