Web and Mobile Smoking Cessation Interventions
This study seeks to develop and then perform a controlled efficacy Randomized Controlled
Trial assessing tobacco abstinence of a best-practices Web-based PC-delivered smoking
cessation intervention (QuitOnline) compared to a Mobile Smartphone-delivered intervention
(MobileQuit). Study participants are randomized to one of two conditions: a Web Only
intervention and the Web+Mobile intervention. The hypothesis is that the Web+Mobile approach
will yield greater efficacy than the Web Only condition.
Trial assessing tobacco abstinence of a best-practices Web-based PC-delivered smoking
cessation intervention (QuitOnline) compared to a Mobile Smartphone-delivered intervention
(MobileQuit). Study participants are randomized to one of two conditions: a Web Only
intervention and the Web+Mobile intervention. The hypothesis is that the Web+Mobile approach
will yield greater efficacy than the Web Only condition.
The primary aims of this project are to:
1. Use an iterative formative development process to create two separate Web-based smoking
cessation programs (Web+Mobile, Web Only).
2. Compare the efficacy of the two smoking cessation programs in terms of tobacco
abstinence. The investigators hypothesize that the Web+Mobile condition will be
significantly more efficacious in terms of tobacco abstinence than the Web Only
condition.
3. Evaluate program usage/participant engagement, treatment acceptability, and consumer
satisfaction. The investigators hypothesize that both conditions will be acceptable and
that the Web+Mobile condition will have significantly greater usage and higher consumer
satisfaction than the Web Only condition.
The secondary aims of this proposal are to:
1. Evaluate the differences between conditions on ancillary tobacco outcomes. The
investigators hypothesize that the participants assigned to the Web+Mobile condition who
continue to smoke will nonetheless report a greater decline in the smoking rate and more
quit attempts.
2. Evaluate predictors and condition moderators of tobacco abstinence. The investigators
will conduct exploratory analyses of the association of treatment outcomes to
participant characteristics (e.g., baseline smoking rate, nicotine dependence level,
partner's tobacco use, prior quitting attempts, prior use of pharmacological adjuncts,
and other demographic factors).
3. Evaluate putative mechanisms of change. The investigators will test whether change in
the putative mechanisms of change (i.e., self-efficacy, program use, use of
pharmacological adjuncts) mediate the association between the intervention condition and
3-month sustained abstinence from the 3 month to 6 month assessments.
