An acceptance and commitment therapy-based intervention for opioid use disorder risk in individuals with cancer: A treatment development study.

This paper describes the iterative development of an evidence-based behavioral intervention for individuals with cancer at risk for opioid use disorder, using the National Institutes of Health Stage Model for Behavioral Intervention Development. Adult patients with cancer from an outpatient palliative care clinic at an academic cancer center, with moderate to high risk of opioid misuse, were enrolled in a treatment development study that aimed to increase psychological flexibility. In this intervention, psychological flexibility is the posited mechanism of change for reduction of opioid use disorder risk. Patients completed baseline (pre-intervention) assessments, a six-session behavioral intervention based in Acceptance and Commitment Therapy, post-intervention assessments, and a semi-structured exit interview. Ten patients with moderate to high risk of opioid misuse completed the intervention. Patients rated the intervention as highly acceptable and were generally highly satisfied. Patients reported finding the coping skills helpful (e.g., mindfulness, cognitive defusion) and reported a preference for more sessions. These treatment development efforts have implications for the development and design of acceptance- and mindfulness-based, targeted interventions for individuals with cancer, receiving palliative care and at risk for opioid use disorder. Specifically, this six-session behavioral intervention to increase psychological flexibility was acceptable to patients and ready to be studied in a pilot RCT.
