Overview
The goal of this clinical trial is to see if telephone support programs help patients and their family caregivers adjust to advanced gastrointestinal cancer. A new telephone counseling program that involves practicing strategies for managing stress and symptoms will be compared to a telephone program involving education on quality-of-life issues and psychosocial support. The main questions it aims to answer are:
Does our telephone counseling program lower the negative impact of patients' fatigue on their activities, emotions, and thinking abilities compared to a telephone program involving education and support? Does our telephone counseling program lower family caregivers' feelings of burden compared to a telephone program involving education and support?
Participants in both study conditions will:
Complete 6 weekly telephone sessions of counseling or education/support Complete a telephone booster session Complete 3 telephone interviews over about 5 months
Description
This trial tests the effects of telephone-delivered acceptance and commitment therapy (ACT) on patient fatigue interference with functioning and family caregiver burden in advanced gastrointestinal (GI) cancer (Aim 1) as well as secondary outcomes (Aim 2). This trial also examines increases in psychological flexibility as a hypothesized mediator of ACT's effects on patient fatigue interference and caregiver burden (Aim 3). Finally, two core aspects of psychological flexibility (i.e., mindfulness/acceptance and commitment/behavior change processes) are examined as exploratory mediators of ACT's effects on patient fatigue interference and caregiver burden (Aim 4). The investigators will recruit advanced GI cancer patients and caregivers from Indiana University Health, Eskenazi Health, MD Anderson Cancer Center, and Northwestern University hospitals. Potentially eligible patients will be mailed a study introductory letter along with a consent form. The letter will have a number to call if they do not wish to be contacted further. A research assistant will call all prospective participants who do not opt out approximately 1 to 2 weeks after the letter is mailed. The research assistant will describe the study as outlined in the consent form and answer any questions. Then the research assistant will administer an eligibility screening to those who consent to participate. With the patient's permission, the primary family caregiver will also be mailed a consent form and contacted via phone to screen for eligibility and obtain consent. Consenting patients and caregivers will complete a 35-minute individual phone assessment at baseline.
Following baseline assessments, patient-caregiver dyads (N = 244) will be randomly assigned in equal numbers to ACT or education/support using a stratified block randomization scheme to balance the groups by patient age (<65 vs. >=65 years) and performance status (patient-reported Eastern Cooperative Oncology Group [ECOG] scores 0 or 1 vs. 2). Dyads in both groups will complete six weekly 50-minute telephone sessions with the first session occurring one week after baseline. Blind interviewers will assess outcomes during 30-minute individual phone assessments at 2 weeks and 3 months post-intervention. Dyads in both conditions will also complete a 30-minute booster phone session one month after the 2-week follow-up. During the booster session, ACT therapists will reinforce and address any barriers to skill practice, and education/support therapists will review key medical center and community resources.
