Brief Summary
Previous findings indicate elevated risk for tobacco use among adults in California who are unemployed and seeking work. In a pilot study, tobacco use was associated with a longer duration of time out of work. This community-based participatory research study aims to deliver and evaluate the impact of a web-based job seeker tailored tobacco cessation intervention vs. a control group in the San Francisco Bay Area. This research investigates whether an employment-centered tobacco treatment intervention is efficacious in supporting abstinence and also associated with more timely engagement of employment.

Outcome Measures
Primary Outcomes (3)
Smoking Status: 7-day point prevalence abstinence
Past 7-day use of conventional cigarettes, alternative tobacco (smokeless, snus), and electronic nicotine devices (ENDS, e.g., e-cigarettes) with details on cigarettes/day, frequency, brand, flavor, strength, and quit attempts. For biochemical verification, participants reporting 7-day PPA at follow-up will have an expired CO sample evaluated using a Bedfont Smokerlyzer. Participants with CO \< 8 ppm indicating nonsmoking will provide a saliva sample for testing with of cotinine with an Accutest NicAlertTM test strip. Salivary cotinine levels \< 15 ng/ml will confirm nonsmoking. Additionally, participants reporting being quit will be asked to provide a urine sample to test for the presence of anabasine (if they have quit smoking but are still using nicotine replacement or another nicotine containing product).
3-months follow-up

Participants with CO \< 8 ppm indicating nonsmoking will provide a saliva sample for testing with of cotinine with an Accutest? NicAlertTM test strip. Salivary cotinine levels \< 15 ng/ml will confirm nonsmoking. Additionally, participants reporting being quit will be asked to provide a urine sample to test for the presence of anabasine (if they have quit smoking but are still using nicotine replacement or another nicotine containing product).

Tobacco Treatment
EXPERIMENTALThe tobacco treatment includes: (a) the ProChange ExpertSystem, a Transtheoretical-model (TTM) tailored, computer-assisted web-delivered program focused on increasing intrinsic motivation, (b) a stage-tailored treatment manual with goal setting for quitting tobacco, and (c) education on proper use of nicotine replacement therapy (NRT, patch plus gum or lozenge) with guidance on obtaining low-cost or free NRT through MediCal, private insurance plans, and community programs.
Usual Care
NO INTERVENTIONUsual care includes: completing the study assessments at baseline, 3- and 6-months and receiving referrals to tobacco treatment in the community, including the state quitline, in line with the public health "Ask, Advise, Refer" model of tobacco cessation intervention.
Interventions
The computer program assesses stage of change and TTM constructs of temptations, decisional balance, and processes of change. Repeat intervention contacts occur at baseline, 3- and 6-months follow-up, providing iterative computerized feedback reflecting prior responses with encouragement for quitting smoking and relapse prevention.
