LiveWell: An Adapted Dialectical Behavioral Therapy Skills Training Protocol for Patients Living With Metastatic Lung Cancer

Participants will be randomized 1:1 to receive LiveWell, an eight-session, telehealth-delivered DBT Skills Training intervention tailored for lung cancer metavivors, or Usual Care. Participants will complete self-report measures at baseline, 8-week follow-up, and 3 month follow-up. It is hypothesized that: 1) RCT methods will demonstrate evidence of feasibility (accrual N=80/20 months, \>80% adherence to assigned interventions and assessments, \<25% attrition) and acceptability (\>3/5 satisfaction study procedures, \>3 mean intervention satisfaction LiveWell); 2) LiveWell participants will demonstrate reductions in distress (primary outcome) and improvements in psychological well-being (illness acceptance, positive affect, tolerance of uncertainty, mindfulness, self-efficacy to manage emotions and symptoms), symptom burden (fatigue, dyspnea, pain), and quality of life (secondary outcomes) compared to Usual Care participants at 8-week follow-up. H3. (Exploratory). To explore the role of emotion regulation as a potential mechanism of change.
