Developing an ACT-based intervention to address lung cancer stigma: Stakeholder recommendations and feasibility testing in two NCI-designated cancer centers.

Few psychosocial interventions have been tailored to meet the unique needs of patients diagnosed with lung cancer. This pilot study developed and tested a six-week intervention for reducing lung cancer stigma. Guided by qualitative interviews conducted with 9 lung cancer patients and 5 thoracic oncology care providers, Acceptance and Commitment Therapy was adapted for treatment of lung cancer stigma (ACT-LCS). In a subsequent single arm pilot study, 22 lung cancer patients reporting high levels of stigma completed the intervention. NCI-designated cancer centers in the Southwestern and Eastern United States. Of 46 eligible patients, 22 provided consent, with 20 completing the intervention (10 in-person, 10 telehealth). Overall stigma decreased across timepoints, largely driven by reductions in internalized stigma. There were also significant reductions in social isolation, sleep disturbance, and fatigue. The ACT-LCS protocol demonstrates preliminary feasibility and acceptability. This intervention may be particularly suited for helping patients navigate feelings associated with internalized stigma.
