A Web-Based Tool to Improve Breast Cancer Survivorship

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to examine the efficacy of a psychosocial eHealth intervention on the proposed primary outcomes, hormone therapy adherence and health related quality of life (HRQoL), in breast cancer survivors. The intervention components include mindfulness-based stress reduction, breast cancer knowledge, stress awareness and management, social support, and enhanced communication. The intervention will be delivered via an online application over an 8-week period. Participants are randomized into either an intervention application (described above) or a control application (health information and general health promotion strategies). Aside from having access to the online application for the recommended 8 weeks with weekly online focus groups, participation in this study includes four assessments: baseline (at the beginning of the research study), post-intervention (8 weeks after baseline), a 6-month follow-up and a 12-month follow-up.

Detailed Description
-----------------
Breast cancer is the most commonly diagnosed cancer among women in the U.S. Approximately 75% to 80% of breast cancer survivors are prescribed HT (hormone therapy) medication for 5 to 10 years following primary treatment. Five years of adjuvant HT among women with non-metastatic cancer reduces the risk of recurrences by 50%. Adherence to HT is also an independent predictor of breast cancer mortality, reducing the risk by up to 28%. HT-side effects, however, are not only a major source of distress but also among the most robust predictors of non-adherence to HT. Therefore, effective management and ability to reduce the burden of these side effects are critically important to achieve optimal HT adherence. Because HT side effects may persist for years and are not easily managed, MBSR's mind-body approach and emphasis on non-judgmental attitudes, acceptance, and uncertainty tolerance may be an especially beneficial approach to helping cancer survivors cope with the burdensome medication-related side effects, thus improving adherence to medication. The investigators propose that a mindfulness-based stress reduction (MBSR) intervention that has been efficacious in reducing HT side effects and improving HRQoL in cancer patients may also prove beneficial in improving HT adherence. After developing a web-based MBSR intervention and refining it via a usability trial, this study will establish the feasibility of a web-delivered, group based MBSR intervention to improve HT medication adherence and HRQoL in patients being treated for breast cancer. It is hypothesized that participants assigned to the MBSR intervention will have better primary outcomes than participants in the control group, which receives standard health information.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Mindfulness-based stress reduction + Hormone Therapy Education<br> | Behavioral: OncoTool Intervention (MBSR + HT education)<br>* OncoTool is a website intended to improve self-management practices for helping cancer patients cope with stress and improve health-related quality of life. OncoTool provides mindfulness-based education and management for dealing with the numerous physical and mental side effects associated with hormone therapy (e.g., muscle and joint pain, vaginal dryness, depressive symptoms). OncoTool is a website designed to improve hormone therapy adherence by improving quality of life, and hormone therapy associated symptom burden. Both intervention and active comparator conditions are administered to participants for 8 weeks.<br>|
| Active Comparator: Hormone Therapy Education + Overall Health Education<br> | Behavioral: Oncotool Control (health +HT education)<br>* OncoTool is a health promotion website with health education on subjects like nutrition and exercise specific to breast cancer survivors, as well as general advice on lifestyle choices and prevention. The Oncotool control has similar HT education content as the experimental content but without the CBT and MBSR state. Both intervention and active comparator conditions are administered to participants for 8 weeks.<br>|

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Self Reported Adherence to Hormone Therapy will be evaluated with the ARMS questionnaire. | The ARMS (Adherence to Refills and Medications Scale) survey is a previously validated patient-report measure of barriers to medication adherence and adherence-related behavior. | T1 (prior to starting intervention), T2 (8 weeks post intervention), T3 (6 months post-intervention), T4 (12 months post intervention) | 
| Change in Health Related Quality of Life will be evaluated with The Functional Assessment of Cancer Therapy-Endocrine (FACT-ES) | The FACT-ES has been used extensively to measure HRQoL. It assesses participant's wellbeing in physical, emotional, social, functional, and concerns specific to endocrine therapy in the last seven days using a five-point response scale. | T1 (prior to starting intervention), T2 (8 weeks post intervention), T3 (6 months post-intervention), T4 (12 months post intervention) | 
| Electronically Verified Hormone Therapy Adherence will be measured using medication event monitoring systems (MEMS) | A MEMS cap is an electronic bottle cap that tracks when participants open their medication bottle. MEMS cap data will be collected continuously during the duration of participation in the study. | MEMS data will be collected continuously during study participation from T1 (prior to starting intervention) to T4 (12 months post-intervention) | 
| Pharmacy reported Adherence to Hormone Therapy will be measured using pharmacological records | Pharmacy data will be pulled once at approximately T4 when a participant finishes the study.
