Intervention is psychosocial counseling utilizing Acceptance and Commitment Therapy for Lung Cancer Stigma (ACT-LCS) as a patient-focused intervention to reduce the self-blame, guilt and inhibited disclosure associated with lung cancer stigma.

All participants in Stage 1, and those randomized to the intervention condition in Stage 2, will receive the Acceptance & Commitment Therapy for Lung Cancer Stigma (ACT-LCS) intervention. The ACT-LC intervention is designed to be delivered as 6 sessions of individual psychotherapy with a trained psychotherapist at a weekly or bimonthly rate, delivered either in person or over the phone. The treatment manual is based in Acceptance and Commitment Therapy (ACT). Therapists are instructed to begin treatment with Module 1. Modules 2-5 can then be administered in any order at the discretion of the therapist, based upon what the therapist thinks is most likely to be helpful to the patient. Module 6 is the final session of treatment.
