Funding Sources • National Cancer Institute • R01-CA-166646 (PI: Bricker) • R01-CA-151251 (PI: Bricker) • R01-CA-120153 (PI: Blalock) • National Institute on Drug Abuse • R21-DA-030646 (PI: Bricker) • K23-DA-0265517 (PI: Heffner) • K99-DA-0037276 (PI: Vilardaga) • Hartwell Innovation Fund (PI: Bricker) • Fred Hutchinson Cancer Research Center (PI: Bricker)

  4. Today’s Tobacco Consequences • The leading cause of preventable death, killing 480K US (Surgeon General, 2014) & 6 million worldwide (WHO, 2013). • Causes lung and multiple cancers, hypertension, CHD, and stroke (Surgeon General, 2014). • $289 Billion in US medical and lost productivity costs (Surgeon General, 2014).

  5. Reach & Efficacy of Smoking Intervention Modalities 30% 20% 10% Individual Efficacy(% Quit at 12 months) 1m 2m 3m 4m Reach(# of million using modality annually) Group Telephone Web

  6. Acceptance & Commitment Therapy (ACT) is a Potential Solution to the Problem of Low Quit Rates

  7. Acceptance of our “baggage” Committed Action in valued direction

  8. Pathways to Acceptance Mindfulness: Present-moment focused attention in the face of challenging circumstances Defusion: Stepping back and watching the process of thinking Self-as-Context: The “part” of us that is aware of what we think, feel, and sense

  9. Pathways to Commitment Values: What deeply matters; want you want your life to be about Action: Doing what it takes, guided by what deeply matters

  10. Acceptance & Commitment Lead to Life-Embracing Behavior Change Mindfulness Values Commitment Acceptance Defusion Self As Context Action Life-Embracing Behavior Change

  11. ACT vs. Standard Treatment

  12. ACT Research Program: “The Wheel”

  13. Telephone-Delivered ACT for Smoking Cessation

  14. Quitlines: Address Barriers to Reach Accessible: In US, 95% have a telephone. (Pew Internet & American Life Project, 2009) Available: All 50 States have a quitline as do most of Europe and Latin America Cost-effective: Covered by insurance, Medicaid, or the state. Costs less than group and with only 25% lower fraction of effectiveness. Relatively brief: about 90 minutes total (3 to 9 sessions) Many demographics make use: Men, minorities, poor

  15. Phase II Trial of Telephone-Delivered ACT vs. CBT for Smoking Cessation (R21DA030646; PI: Bricker) Primary Aim 1: Compare ACT with CBT on implementation outcomes Primary Aim 2: Demonstrate that ACT, as compared to CBT, has trend toward cessation. Primary outcome: 30 pp at 6 month post tx Primary Aim 3: Determine mediation by acceptance of smoking cues and commitment to quitting

  16. TALK Consort Diagram Screened (n=237) • Excluded (n= 87) • Declined Eligibility Survey (n=46) • Ineligible (n=36) • Did not take Baseline Survey (n=5) Enrollment Eligible (n=150) • Excluded (n= 29) • Did not confirm by phone (n=29) Randomized (n= 121) • Allocated to CBT (n=62) • Received 5 calls (n=3) • Received 4 calls (n=6) • Received 3 calls (n=21) • Received 2 calls (n=10) • Received 1 calls (n=16) • Received 0 calls (n=6) • Allocated to intervention (n=59) • Received 5 calls (n=28) • Received 4 calls (n=4) • Received 3 calls (n=5) • Received 2 calls (n=7) • Received 1 calls (n=7) • Received 0 calls (n= 8) Allocation Lost to follow-up 3-months (n= 19) Lost to follow-up 6-months (n=16) Lost to follow-up 3-months (n= 22) Lost to follow-up 6-months (n= 24) Follow-Up Analysed for 3 months (n=59) Analysed for 6 months (n=59) Analysed for 3 months (n=62) Analysed for 6 months (n=62) Analysis

  17. Aim 1: Baseline Demographics & Retention

  18. Aim 1: Baseline Smoking & Social Env at Baseline & Retention

  19. Calls Attempted & Completed

  20. Aim 1: Treatment Competence

  21. Aim 2: NRT Usage

  22. Aim 2: Tx Satisfaction

  23. Aim 3: 6M Quit (30D PP)

  24. 6-Month Quit (30D PP) in Key Baseline Subgroups

  25. Aim 3: Impact on Avoidance

  26. Aim 3: ACT3M Avoidance6M Quit

  27. Conclusions: Telephone ACT is… Feasible to deliver Acceptable to quitline callers Showing promising quit rates compared to CBT Operating according to its theoretical model Ready for a fully-powered RCT

  28. Next Grant… Results stimulated an NIDA research grant application for $3 million Fully-powered RCT of 1100 participants with one year follow-up June 2014: Perfect Score in Study Section!
