A Novel Intervention for Patients With Cancer

This research study is being done to develop an intervention for psychological symptoms that patients diagnosed with cancer may experience. Psychological symptoms may include thoughts, feelings, emotions, and memories

The names of the study intervention and research activities involved in this study are/is:

* Acceptance \& Commitment Therapy (ACT) for Cancer (involving 6 sessions with a licensed clinical psychologist)
* Questionnaires
* Post-study interview

Consistent with the NIH Stage Model for Behavioral Intervention Development, the investigators have adapted an existing, empirically-validated intervention, Acceptance and Commitment Therapy (ACT), to address substance use disorder risk during cancer care. The core components of ACT are particularly well-suited to address the psychological processes underlying opioid misuse in individuals treated for cancer pain. The overarching aim is to assess the feasibility and acceptability of the intervention by conducting a randomized pilot trial of the revised intervention ("ACTION") for cancer patients on opioid therapy, and at risk for SUD.

This research study is a Feasibility Study, which is the first-time investigators are examining this psychological intervention in patients with cancer who are prescribed opioids and are receiving palliative care. This study is being conducted to develop a psychological intervention designed specifically for individuals with cancer. The purpose of this study is to determine how practical this intervention is, to determine patient satisfaction, and test the study procedures. The aims are to:

1. determine whether this intervention will be appropriate for further testing;
2. identify which parts of the protocol and procedures need to be modified; and
3. assess patients' reactions to this intervention.

This research study involves a psychological intervention for thoughts, feelings, emotions, and memories that individuals diagnosed with cancer may have.
