A Dialectical Behavior Therapy Skills Training Intervention for Cigarette Smoking by Patients with Cancer: Focused Qualitative Inquiry Prior to Feasibility Trial

This study utilized focused qualitative inquiry with cancer patients and clinicians to evaluate a proposed virtual Dialectical Behavior Therapy Skills Training intervention for smoking cessation, revealing strong enthusiasm for the program's core skills while identifying specific areas for refinement prior to a feasibility trial.

The Gist

Imagine you are navigating a stormy sea. You have a boat (your body) that has just been hit by a massive wave (a cancer diagnosis). To make matters worse, you've been using a specific tool to stay afloat for years—a cigarette. It's your "life raft" for stress, anxiety, and tough emotions. But now, your doctor tells you that this life raft is actually leaking and making the storm worse. You need to let it go, but you don't know how to swim without it.

This research paper is about a team of doctors and researchers trying to build a new, better life raft for these patients. They call it DBT-ST (Dialectical Behavior Therapy – Skills Training).

Here is the story of how they designed this new raft, asked for feedback from the people who would use it, and what they learned.

1. The Problem: The Old Tools Aren't Enough

Usually, when people try to quit smoking, doctors give them the standard toolkit: "Motivational talks" (think of it as a pep talk) and "Cognitive therapy" (changing your thoughts). It works for many, but for people with cancer who have smoked for decades, it's like trying to fix a leaky boat with a piece of gum. The stress of cancer is just too heavy, and the emotional pain is too deep. They need something stronger.

2. The Solution: The "Swiss Army Knife" of Coping

The researchers decided to borrow a tool from a different toolbox: DBT. Think of DBT as a Swiss Army Knife for your emotions. Instead of just one blade (like "don't smoke"), it has many tools:

• Mindfulness: Learning to "press the pause button" on your brain when things get crazy.
• Emotion Regulation: Learning how to calm a storm inside your chest without needing a cigarette.
• Distress Tolerance: Learning how to sit through a painful moment without making it worse.

They built an 8-week virtual group class to teach these skills. Imagine a weekly Zoom meeting where patients learn how to be present, manage their feelings, and handle stress, all while supporting each other.

3. The Test Drive: Asking the Passengers

Before they launched this new program for a big scientific trial, they did something smart. They invited two groups of people to sit in the driver's seat and give feedback:

• The Passengers: 8 patients with cancer who smoke (or used to).
• The Captains: 9 doctors, nurses, and therapists who treat these patients.

They asked them: "Does this plan make sense? Will you actually use it? What needs to be fixed?"

4. The Feedback: What Worked and What Didn't

The "Yes!" Moments (The Good Stuff):

• The Group Vibe: Everyone loved the idea of a group. It's like a support squad. One patient said, "I've had people yell at me to quit, but no one has ever supported me." Being with others going through the same storm made them feel less alone.
• The Skills: The "Swiss Army Knife" tools were a hit. Patients loved the idea of learning how to breathe through a panic attack or handle a bad day without reaching for a cigarette. Doctors thought these skills would be useful for everything in life, not just quitting smoking.
• Virtual is Vital: Patients loved that they could join from home. It saved them from the hassle of driving to a clinic when they were already tired from chemo.

The "Hmm..." Moments (Things to Fix):

• The Time Commitment: The original plan was 90 minutes per session. Patients and doctors both said, "Whoa, that's too long!" It's like asking someone to run a marathon when they are already exhausted. They suggested cutting it down to 60 minutes.
• The "Not Ready" Crew: The plan was to let anyone join, even people who didn't want to quit yet. Some patients worried these people would drag the group down, while some doctors thought they might get inspired by the motivated ones. It was a mixed bag.
• The Tech Worry: Doctors were worried that older patients or those with poor internet would get left behind. Patients, however, said, "Don't worry, we can handle the Zoom!" The doctors were overestimating the fear of technology.

5. The Final Blueprint: Tweaking the Engine

Based on this feedback, the researchers are going to tweak their plan before the big trial:

• Shorten the sessions to 60 minutes (so it's less of a burden).
• Offer evening slots to fit around busy schedules.
• Assign a "Tech Buddy" to help anyone who gets stuck logging in.
• Simplify the language so it doesn't sound like a religious or overly complex psychology lecture.
• Make the content concrete, focusing on real-life triggers like "what to do when you're stressed at the hospital."

The Bottom Line

This paper is essentially a dress rehearsal. The researchers built a new engine for a car (the DBT program), but before they put it on the highway, they asked the drivers (patients) and the mechanics (doctors) to kick the tires.

The verdict? The engine is powerful and the drivers are excited. They just need to adjust the seat height (shorter sessions) and make sure the GPS is clear (simpler language). If this works, it could be a game-changer, helping cancer patients not only quit smoking but also learn how to navigate the stormy seas of life with a much better set of tools.

Technical Summary

1. Problem Statement

Despite evidence that smoking cessation significantly improves cancer treatment outcomes, survival rates, and quality of life, approximately 12.7% of patients with cancer continue to smoke. Standard-of-care cessation treatments (motivational/cognitive therapy plus medication) often fail for patients with long-term smoking histories and repeated quit failures. These patients frequently rely on smoking as a primary coping mechanism for the intense psychological distress, anxiety, hopelessness, and emotional dysregulation induced by a cancer diagnosis and treatment. There is a critical need for novel interventions that target emotion regulation and distress tolerance rather than just motivation or withdrawal management.

2. Methodology

The study employed a focused qualitative inquiry as part of Stage 1A of the NIH Stage Model for behavioral intervention development. The goal was to refine a proposed intervention before a feasibility clinical trial.

• Intervention Design: The researchers developed an eight-session, virtual group intervention based on Dialectical Behavior Therapy – Skills Training (DBT-ST). The curriculum included:
  • Introduction/Conclusion sessions.
  • Mindfulness (2 sessions).
  • Emotion Regulation (2 sessions).
  • Distress Tolerance (2 sessions).
  • Goal: To teach patients skills to manage stress and emotions without relying on smoking.
• Participants:
  • Patients (n=8): English-speaking adults (18+) with active or remitted cancer who were current smokers or had quit. The sample was racially representative of the center's smoking population (2 Black, 6 White; 2 female, 6 male; mean age 60.6).
  • Clinicians (n=9): Oncology physicians, nurses, advanced practice providers, and psychotherapists (7 female, 2 male; mean age 44.0).
• Data Collection: Semi-structured individual interviews were conducted via phone or video. Participants reviewed the intervention structure, content, recruitment strategies, and proposed patient-reported outcome measures (PROMs).
• Data Analysis: Interviews were transcribed and analyzed using thematic analysis in ATLAS.ti software. A codebook was developed using both deductive (based on interview guides) and inductive (emerging from data) strategies. Two expert researchers coded the data independently, resolving discrepancies through consensus. Data saturation was reached when no new insights emerged.

3. Key Contributions

• Novel Application: This is the first known adaptation of DBT-ST specifically for smoking cessation in a cancer population, moving beyond traditional motivational approaches to address the transdiagnostic mechanisms of emotional dysregulation.
• Stakeholder-Driven Refinement: The study provides a rigorous, pre-trial validation process by integrating feedback directly from both the target patient population and clinical providers, ensuring the intervention is feasible and culturally/clinically appropriate.
• Identification of the "Perception Gap": The study highlighted a significant discrepancy between how patients and clinicians perceive barriers to virtual care and data collection, a finding crucial for future trial design.

4. Results

The qualitative analysis yielded several key themes regarding the proposed intervention:

A. Intervention Structure & Format

• Group Format: Strongly supported by both groups for providing social support, validation, and peer accountability. However, some clinicians noted that highly introverted patients might prefer individual therapy.
• Virtual Setting: Patients were uniformly enthusiastic about the virtual format due to convenience and accessibility. Clinicians were mixed, expressing concerns about technological barriers for older, rural, or low-income patients and potential disengagement, though patients did not report these as barriers.
• Session Length: The proposed 90-minute sessions were deemed too burdensome. Both groups recommended reducing sessions to 60 minutes.
• Inclusion Criteria: There was debate regarding including patients "not ready to quit." Some clinicians believed peer commitment could motivate them, while some patients doubted their own ability to commit.

B. Intervention Content (DBT-ST Skills)

• High Acceptance: Skills in mindfulness, emotion regulation, and distress tolerance were viewed as highly practical, transferable to life beyond smoking, and essential for managing cancer-related stress.
• Distress Tolerance: Specifically praised for providing concrete physical strategies to handle cravings.
• Concerns: Some clinicians worried that "mindfulness" might be perceived as religious or too abstract for patients with lower health literacy or specific religious backgrounds.

C. Recruitment and Engagement

• Strategies: Participants suggested leveraging trusted healthcare providers (oncologists, nurses) for referrals and framing the program as a "life skill" intervention rather than a "research trial" to reduce stigma, particularly among minority groups.
• Barriers: Identified barriers included time constraints, treatment fatigue, and fear of judgment.

D. Outcome Measures

• Patients found the proposed surveys (assessing depression, anxiety, stress, etc.) relevant and easy to understand.
• Clinicians expressed concern that the surveys might be too long, repetitive, or confusing for patients, potentially creating a burden.

5. Significance and Implications

The study concludes that the DBT-ST intervention holds significant promise for improving smoking cessation outcomes in cancer patients by addressing the underlying emotional and distress mechanisms that standard care often misses.

Immediate Implications for Future Trials (Stage 1B):
Based on the qualitative findings, the research team has committed to the following modifications before the feasibility trial:

1. Reduce Session Length: From 90 minutes to 60 minutes.
2. Scheduling: Offer sessions in late afternoons or evenings to accommodate patient schedules.
3. Technical Support: Assign a staff member to each session to assist with virtual connectivity.
4. Content Adaptation: Ensure language is concrete, value-neutral, and accessible (avoiding religious connotations of "mindfulness").
5. Material Accessibility: Provide materials for those who miss sessions due to illness.
6. Recruitment Framing: Market the program as a stress-management life skill rather than a research study to improve trust and enrollment.

This inquiry successfully validated the theoretical framework of the intervention while identifying practical barriers, ensuring the subsequent feasibility trial is optimized for patient engagement and retention.
