Smoking Cessation

Pro-Change’s Smoking Cessation program assists smokers in all stages of quitting and helps those who have quit to stay smoke-free.

Fifteen percent of U.S. adults smoke. Most of those smokers want to quit; they’re just not ready.

Multiple studies have found TTM based individualized interventions for smoking cessation to produce long-term abstinence rates within the range of 22 – 26%. Those interventions have also consistently outperformed alternative interventions including action-oriented self-help programs1, non-interactive manual-based programs2, and other common interventions.3 These interventions continued to move smokers to abstinence even after the studies concluded. For a summary of smoking cessation clinical outcomes, see Velicer et al., 2007.4

The Smoking Cessation Program, available in English and Spanish, is a two-part, self-administered program that includes:

  • Online computer tailored intervention (CTI) with questions and feedback tailored to each individual’s needs
  • Dynamic web activities matched to the individual’s readiness to change (e.g., stories and suggestions from people who quit; cost and savings calculators; a nicotine dependency survey and feedback; a timeline to better health and much more.

Fully tailored text messaging is available. In a recent trial, the addition of tailored text messaging increased the effectiveness of our best practices by nearly 15 percentage points to 40.3%. In addition, the text messages increased engagement with the program, and qualitative feedback regarding the text message portion of the program has been overwhelmingly positive.

Online Program

We have self-directed and coaching versions of our online Smoking Cessation program.

Fully tailored text messaging is available.

Youth Tobacco Cessation

We have a tobacco cessation program specifically for youth built on the same Transtheoretical Model principals as the adult program.

Effectiveness

In a recent trial, the addition of tailored text messaging increased the effectiveness of our best practices by nearly fifteen percentage points. In addition, the text messages increased engagement with the program.

(Sample = 446)
At 3-month follow-up:

  • 25.7% successfully quit smoking
  • 40.3% successfully quit smoking when the program was augmented with tailored text messaging

(Jordan & Evers)

(Sample = 224 in inpatient psychiatry unit)
At 18-month follow-up:

  • 20% successfully quit smoking

(Prochaska et al., 2014, Hickman, et al, 2015)

Previous Studies

  • Long-Term abstinence rates of 22% – 26% have been found for interventions tailored on the 14 TTM variables for smoking cessation
