Remote Mindfulness Breathing Training for Patients Undergoing Chemotherapy

September 1, 2026 updated by: Chen Lei Yu, Tri-Service General Hospital (TSGH)

Effects of Remote Mindfulness Breathing Training on Symptom Distress, Fatigue and Psychological Well-Being in Patients Undergoing Chemotherapy

This randomized controlled trial will evaluate the effects of a mobile-delivered remote mindfulness breathing training program on symptom distress, fatigue, anxiety, and depression in adults with cancer who are receiving chemotherapy.

A total of 80 participants will be randomly assigned in a 1:1 ratio to either an intervention group or a control group. The intervention group will complete 5 to 10 minutes of guided mindfulness breathing practice each day for 3 weeks using a mobile-accessible video. The control group will receive usual care and one approximately 5-minute mindfulness breathing instruction session. Outcomes will be assessed at baseline and at the end of the 3-week intervention.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a prospective, two-arm, assessor-blinded randomized controlled trial involving adults with any type of cancer who are receiving chemotherapy in inpatient units or at the Tri-Service General Hospital breast surgery outpatient clinic.

After providing written informed consent and completing the baseline assessment, eligible participants will be randomly allocated by computer in a 1:1 ratio to the intervention group or the control group. The intervention group will receive a mobile-delivered remote mindfulness breathing training program and will be instructed to practice with a guided video for approximately 5 to 10 minutes daily for 3 weeks. The control group will receive usual care and one approximately 5-minute mindfulness breathing stress-reduction instruction session.

Study assessments will be conducted before the intervention and at the end of week 3. Symptom distress will be assessed using the National Comprehensive Cancer Network Distress Thermometer, fatigue using the Brief Fatigue Inventory, anxiety using the Generalized Anxiety Disorder-7, and depression using the Patient Health Questionnaire-9. To reduce measurement bias, the post-intervention assessment will be conducted by a research assistant who is unaware of the participants' group assignments.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Distress Level Assessed by the NCCN Distress Thermometer
Time Frame: Baseline and Week 3
The NCCN Distress Thermometer is a single-item self-report scale ranging from 0 (no distress) to 10 (extreme distress). Higher scores indicate greater distress.
Baseline and Week 3
Change in Fatigue Assessed by the Brief Fatigue Inventory
Time Frame: Baseline and Week 3
The Brief Fatigue Inventory contains 9 items rated from 0 to 10. The global fatigue score is calculated as the mean of the completed items, with higher scores indicating greater fatigue severity and interference.
Baseline and Week 3
Change in Anxiety Assessed by the Generalized Anxiety Disorder-7
Time Frame: Baseline and Week 3
The Generalized Anxiety Disorder-7 contains 7 items rated from 0 to 3, producing a total score ranging from 0 to 21. Higher scores indicate greater anxiety severity.
Baseline and Week 3
Change in Depression Assessed by the Patient Health Questionnaire-9
Time Frame: Baseline and Week 3
The Patient Health Questionnaire-9 contains 9 items rated from 0 to 3, producing a total score ranging from 0 to 27. Higher scores indicate greater depressive symptom severity.
Baseline and Week 3
