Brief Summary:
The long-term goal is to improve the quality of life of children and their parents who smoke tobacco by facilitating parental smoking cessation in a way that is easy to administer yet effective. We aim to accomplish this goal by administering an interactive computer-based program that will facilitate motivation and readiness to engage in smoking cessation by providing personalized feedback about the financial and health effects of the parent's smoking. We will compare the changes in motivation and readiness to quit smoking after the parent has taken the computer-based program and compare them to the changes in motivation and readiness to quit in parents who receive only information about the Oklahoma Tobacco Helpline. We will also measure salivary cotinine levels in both parents and children, to objectively measure changes in smoking habits and secondhand smoke exposure. Our hypothesis is that our computer-based program will cause a greater increase in motivation and confidence to quit smoking in the group that receives the customized feedback than the group that receives only information about the Tobacco Helpline. We also predict that both parent and child cotinine levels will show a greater decrease in the group randomized to receive personalized feedback.

Arm Intervention/treatment
Active Comparator: Feedback
Participants in this group will receive individualized feedback based on their stage of change. Feedback will include health effects of smoking, money spent per month and per year on cigarettes, time spent smoking compared with time spent doing other daily tasks, and how the participant compares to past study participants in average number of cigarettes per day used and level of addiction.
Behavioral: Personalized Feedback
Personalized feedback reflecting the participant's current level of nicotine addiction, money spent on cigarettes, time spent smoking, and health effects of smoking.

No Intervention: No Feedback- Treatment as Usual (TAU)
Participants will take the computer based survey, but will only receive a number to the Oklahoma Tobacco Helpline (Treatment-as-usual condition) instead of feedback.

Primary Outcome Measures :
  1. Self-Reported Readiness and Motivation to Quit Smoking [ Time Frame: Baseline, 1-month, 6-months, 12-months ]
    We will assess changes in self-reported readiness and motivation to quit smoking.

  2. Parent and Child Salivary Cotinine [ Time Frame: Baseline, 1-month, 6-months, and 12-months ]
    We will assess change in parent and child salivary cotinine throughout the course of the study.

  3. Change in self-reported cigarette use [ Time Frame: baseline, 1-month, 6-months, and 12-months ]
    We will assess changes in self-reported cigarette use throughout the study.
