Telephone Support for Advanced Gastrointestinal Cancer Patients and Caregivers

Study Overview
=================
Brief Summary
-----------------
This trial tests telephone-based Acceptance and Commitment Therapy (ACT), a type of psychotherapy, to reduce fatigue interference with activities, mood, and cognition in advanced gastrointestinal (GI) cancer patients and family caregiver burden. ACT includes mindfulness exercises (e.g., meditations, performing activities with greater awareness), identifying personal values (e.g., family, spirituality), and engaging in activities consistent with these values. A total of 40 patient-caregiver dyads were randomly assigned in equal numbers to either the ACT intervention or an education/support condition. Dyads in both conditions participated in six weekly 50-minute telephone sessions. Outcomes were assessed at baseline, 2 weeks post-intervention, and 3 months post-intervention. The investigators hypothesize that ACT will lead to improved primary and secondary outcomes as compared to education/support. Study findings will inform a large-scale trial of intervention efficacy.

Detailed Description
-----------------
This trial evaluates the feasibility, acceptability, and preliminary efficacy of telephone-based Acceptance and Commitment Therapy (ACT) on fatigue interference in advanced gastrointestinal (GI) cancer patients and family caregiver burden as well as secondary outcomes. The study team recruited advanced GI cancer patients receiving care at the Indiana University Simon Cancer Center or Eskenazi Health hospital. Potentially eligible patients were mailed an introductory letter signed by their oncologist and the PI along with a consent form. The letter had a number to call if they did not wish to be contacted further. A research assistant (RA) called all prospective participants who did not opt out approximately 1 to 2 weeks after the letter was mailed. The RA described the study as outlined in the consent form and answered any questions. Then the RA administered an eligibility screening to those who consented to participate. Eligible and consenting patients identified a potentially eligible family caregiver. If the family caregiver was eligible and consented to participate, then the patient and caregiver each completed a baseline phone assessment. Following baseline assessments, patient-caregiver dyads (N = 40 dyads) were randomly assigned in equal numbers to ACT or education/support using a stratified block randomization scheme to balance the groups by patient performance status (patient-reported Eastern Cooperative Oncology Group [ECOG] scores 0 or 1 vs. 2). Dyads in both study conditions completed six weekly 50-minute telephone sessions with the first session occurring one week after baseline. For ACT participants, adherence to home practice during the past week was assessed and recorded during each session. Feasibility will be examined via accrual, attrition, and adherence rates, and acceptability will be evaluated using a mixed methods approach (qualitative and quantitative). Blind interviewers assessed outcomes during follow-up phone assessments at 2 weeks and 3 months post-intervention.

Design Details

Primary Purpose: Supportive Care
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Advanced gastrointestinal cancer patient-family caregiver dyads (N = 40) were randomly assigned in equal numbers to Acceptance and Commitment Therapy (ACT) or education/support using a stratified block randomization scheme to balance the groups by patient performance status (patient-reported Eastern Cooperative Oncology Group [ECOG] scores 0 or 1 vs. 2).
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Acceptance and Commitment Therapy<br>Patients and caregivers in the ACT arm learn new and more adaptive ways to respond to difficult internal experiences (e.g., fatigue, thoughts, and feelings). | Behavioral: Acceptance and Commitment Therapy<br>* Across six weekly 50-minute sessions, advanced GI cancer patients and caregivers practice various mindfulness exercises, clarify their values, and set specific goals in alignment with their values. Through in-session and home practice of skills, participants learn new and more adaptive ways to respond to unwanted internal experiences (e.g., fatigue, distress). Participants receive handouts on session topics and a compact disc (CD) that we developed to guide mindfulness practices.<br>|
| Active Comparator: Education/Support<br>Patients and caregivers in the education/support arm discuss their cancer-related concerns and receive education on services available in their medical center and community. | Behavioral: Education/Support<br>* Across six weekly 50-minute sessions, advanced GI cancer patients and caregivers are directed to resources for practical and health information and contact information for psychosocial services. Sessions include an orientation to the patient's medical center and treatment team, education regarding common quality-of-life concerns experienced by cancer patients and caregivers, and an overview of medical center and community resources for addressing these concerns. The therapist also describes resources for addressing financial concerns and methods of evaluating health information available via the Internet and other modalities. Participants receive handouts summarizing session topics and are asked to review them as homework.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Fatigue Interference Subscale of Fatigue Symptom Inventory | Seven items are rated on 11-point scales (0=no interference to 10=extreme interference) that assess the extent to which fatigue in the past week interfered with general level of activity, ability to bathe and dress, normal work activity (including housework), ability to concentrate, relations with others, enjoyment of life, and mood. The seven items are summed with higher total scores indicating greater fatigue interference. The total score range is 0 to 70. This is the primary outcome for patients. | 2 weeks and 3 months post-intervention | 
| Short-form of Zarit Burden Interview | Twelve items are rated on 5-point scales (0=never to 4=nearly always) that assess personal strain and role strain due to caregiving. The 12 items are summed with higher total scores indicating greater caregiving burden. The total score range is 0 to 48. This is the primary outcome for caregivers. | 2 weeks and 3 months post-intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient-Reported Outcome Measurement Information System (PROMIS) Sleep-Related Impairment | This 8-item measure assesses the perceived interference of sleep problems with activities, mood, and cognition (e.g., difficulty concentrating or completing tasks). Each item is rated on a scale from 1 (not at all) to 5 (very much). Item #2 is reverse-scored and then the 8 items are summed with higher total scores indicating greater sleep-related impairment. The total scores are converted to T-scores with a range from 30.0 to 80.1. Higher T-scores indicate a worse outcome. The population mean for T-scores is 50 with a standard deviation of 10. This is a secondary outcome for patients. | 2 weeks and 3 months post-intervention | 
| PROMIS Ability to Participate in Social Roles and Activities | This 6-item measure assesses participants' ability to participate in social roles and activities. The items measure difficulty engaging in social and recreational activities as well as usual work (including housework). Each item is rated on a scale from 1 (never) to 5 (always) and is reverse coded. Then the six items are summed with higher total scores indicating greater ability to participate in social roles and activities. The total scores are converted to T-scores with a range from 26.7 to 65.0 with higher scores indicating a better outcome. The population mean for T-scores is 50 with a standard deviation of 10. This is a secondary outcome for both patients and caregivers. | 2 weeks and 3 months post-intervention | 
| Acceptance and Action Questionnaire-II | This 7-item measure assesses psychological flexibility, or the ability to fully experience the present moment while persisting in actions aligned with personal values. Each item is rated on a scale from 1 (never true) to 7 (always true). The seven items are summed with higher total scores indicating greater levels of psychological inflexibility. The total score range is 7 to 49. This is a secondary outcome for both patients and caregivers. | 2 weeks and 3 months post-intervention | 
| McGill Quality of Life Questionnaire-Revised | This 15-item measure evaluates physical, psychological, existential, and social quality of life in patients with serious illnesses. Each of the 4 subscale scores (i.e., physical, psychological, existential, and social quality of life) is the sum of the items with higher scores indicating better quality of life. Items are rated on 0 to 10 scales. The physical quality of life subscale is the sum of 3 items (2 items reverse-coded) with a range of 0 to 30. The psychological quality of life subscale is the sum of 4 items (all items reverse-coded) with a range of 0 to 40. The existential quality of life subscale is the sum of 4 items (1 item reverse-coded) with a range of 0 to 40. The social quality of life subscale is the sum of 3 items (none reverse-coded) with a range of 0 to 30. This is a secondary outcome measure for patients. | 2 weeks and 3 months post-intervention | 
| PROMIS Global Health | This 10-item measure assesses global health, including physical, mental, and social well-being. With the exception of pain, which is rated on a 0 to 10 scale, all items are rated on 5-point scales from 1 to 5. The item on pain is recoded from a 0-10 to a 1-5 scale and reverse-scored. Two additional items are reverse-scored. Then four of the items are summed, with higher physical quality of life subscale scores indicating better physical quality of life. Four other items are also summed with higher psychological quality of life subscale scores indicating better psychological quality of life. The subscale scores are converted to T-scores with a range from 16.2 to 67.7 for physical quality of life and a range from 21.2 to 67.6 for psychological quality of life. Higher T-scores for the physical and psychological quality of life subscales indicate a better outcome. The population mean for T-scores is 50 with a standard deviation of 10. This is a secondary outcome measure for caregivers. | 2 weeks and 3 months post-intervention | 
| Value Progress Subscale of the Valuing Questionnaire. | This 5-item subscale assesses progress in living according to one's personal values, a construct related to activity engagement. Items are rated on 0 to 6 scales. The 5 items are summed with higher total subscale scores indicating greater progress in living according to one's personal values. The total subscale score range is 0 to 30. This is a secondary outcome measure for patients and caregivers. | 2 weeks and 3 months post-intervention |
