About

Cancer and cancer treatment often lead patients and survivors to experience a host of chronic symptoms, of which sleep disturbances are a major concern. Smartphone-based meditation via an already-developed app (i.e., Calm) is a unique and novel way of providing a potentially helpful symptom-management strategy to cancer patients and survivors. Our hypothesis is that cancer patients/survivors using the Calm smartphone app for eight weeks will see improved sleep disturbance (primary outcome) as well as anxiety, depression, pain intensity, global health, quality of life, emotional regulation, and mindfulness when compared to a time and attention-matched health education podcast control group. Cancer patients/survivors (n=300) will be randomly assigned to an intervention or control group for eight weeks, with study outcome measurement occurring at baseline, post-intervention (i.e., week eight), and follow-up (i.e., week 20).

Full description

Cancer patients and survivors struggle with chronic symptom burden, including sleep disturbance, fatigue, depressive symptoms, and anxiety, among others. Sleep disturbance is one of the most common complaints among cancer patients and survivors (reported in as many as 85% of cancer patients and survivors, depending on the type of cancer), but is often not fully addressed by pharmacologic intervention alone. Therefore, cancer patients and survivors often turn to non-pharmacologic approaches.

Currently, cognitive behavioral therapy for insomnia (CBT-I) is the most available, evidence-based, non-pharmacologic treatment strategy to manage sleep disturbances in cancer patients and survivors. However, this treatment modality is time-consuming and intensive, requiring patients to frequently meet in-person with therapists and physicians at sites/clinics. This approach may not be sustainable in the long term, as cancer patients often report barriers to attending in-person interventions, including fatigue, transportation, and scheduling difficulties. Although remote delivery of CBT-I has been suggested as an alternative,1 only a single pilot study has investigated this possibility. The pilot study delivered CBT-I via a mobile app, but was limited by the small sample size (n=19) and no control group. Further research is needed testing the delivery of efficacious, non-pharmacologic interventions remotely to cancer patients and survivors for the management of sleep disturbance.

Smartphones, due to their increasing ubiquity among cancer patients and survivors, offer a novel medium through which to deliver non-pharmacologic sleep-management interventions. In a recent survey of 1,300 cancer patients, 71% reported owning a mobile smartphone. A 2018 survey of 631 cancer patients demonstrated that 74% regularly use a smartphone, and 39% expressed an interest in supportive care information via mobile apps. Meditation is a non-pharmacologic intervention that has a growing body of literature to document its benefits for sleep in cancer patients, and it is a less time-consuming and resource-intensive strategy when compared to CBT-I. Further research needs to examine the potential efficacy of meditation as an efficacious non-pharmacologic strategy for the self-management of sleep disturbances.

The investigators have successfully delivered meditation to hematological cancer patients previously via the Calm app with moderate effects demonstrated on sleep disturbance. However, more research is needed to test the preliminary effects of smartphone-based meditation among cancer patients for sleep disturbance as compared to an active control group. In the proposed study, the investigators will recruit a national sample of cancer patients and survivors (N=300) within two years of cancer diagnosis, to pilot test an eight-week smartphone-based meditation intervention (i.e., Calm; n=150) on sleep disturbance (primary outcome) as compared to a smartphone-based health education podcast control group (n=150). The investigators will aim to recruit 50% men into the study.

STUDY OBJECTIVES

Objective 1: Explore the preliminary effects of eight weeks of daily meditation delivered using the Calm app on sleep disturbance in cancer patients and survivors within two years of diagnosis as compared to a smartphone-based podcast control group.

The primary hypothesis for this objective is that those in the Calm group will experience improvements in sleep disturbance greater than those experienced by the podcast control group at eight weeks.

Objective 2: Explore the preliminary effects of eight weeks of daily meditation delivered using the Calm app on cancer patients and survivors within two years of diagnosis on anxiety, depression, pain intensity, global health, quality of life, emotional regulation, and mindfulness as compared to a smartphone-based podcast control group.

The primary hypothesis for this objective is that those in the Calm app group will experience improvements in anxiety, depression, pain intensity, global health, quality of life, emotional regulation, and mindfulness greater than those experienced by the podcast control group at eight weeks.

Exploratory Objective 3: Explore the sustained effects of meditation delivered using the Calm app on cancer patients and survivors (i.e., 12-week follow-up).

The primary hypothesis for this objective is that those in the Calm app group will experience improvements across outcomes compared to baseline that are sustained at 20 weeks.

Calm Meditation

Experimental group

Description:

The intervention will be 8-weeks in duration and will consist of a series of pre-approved meditation classes. Patients will be asked to participate in at least 10 min/day of meditation (i.e., \~70 min/week). Week 1-4 will consist of the "7 Days of Calm" followed by the "21 Days of Calm", which are introductory courses offered by Calm and provide basic, introductory meditation classes for beginners. Weeks 5-8 will consist of patients participating in the "Daily Calm" that Calm provides, consisting of 10-12 min meditation classes that have a unique focus each day. Patients will be instructed to participate in at least 10 min/day of meditation, but will be encouraged to do more if they can.

Health Education Podcast

Active Comparator group

Description:

The control group will serve as an active control group and will be matched for time and attention to the intervention group. Participants assigned to the control group will be asked to listen to/view 10-min/day (i.e., \~70 min/week) of health education podcasts via a smartphone app. Topics covered in the health education control vary and will be aimed at providing useful and informative health-related information pertinent to cancer patients. The podcast app was developed by an independent app developer, and it was designed to mirror the type of functionality that the Calm app offers its users.
