RecruitingBehavioural interventionTelemedicine-mHealth Symptom Cluster Intervention for Advanced Cancer Patients: Finding Our Center Under Stress (FOCUS)This clinical trial studies whether a telemedicine-mobile health (mHealth) intervention, Finding Our Center Under Stress (FOCUS), improves symptom management in patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Patients with advanced cancer often experience difficulties with sleep, worry, fatigue, and sometimes mood. FOCUS uses cognitive-behavioral and acceptance and commitment therapy strategies designed to improve these symptoms. Cognitive-behavioral therapy is a type of counseling focused on how the ways that people think (cognitive) and what they do (behavioral) can change the way they feel. Acceptance and commitment therapy is an intervention which has demonstrated success in treating symptoms by teaching strategies to focus time and energy on valued activities despite symptoms. This may be an effective way for patients with advanced cancer to manage their symptoms.
