    Background: The study aims to test the differential effects of a web-based text and a web-based video-driven computer-tailored approach for lower socio-economic status (LSES) and higher socio-economic status (HSES) smokers which incorporate multiple computer-tailored feedback moments. The two programs differ only in the
    mode of delivery (video- versus text-based messages). The paper aims to describe the development and design of the two computer-tailored programs.
    Methods/design: Respondents who smoked at the time of the study inclusion, who were motivated to quit within the following six months and who were aged 18 or older were included in the program. The study is a randomized control trial with a 2 (video/text) * 2(LSES/HSES) design. Respondents were assigned either to one of the intervention groups (text versus video tailored feedback) or to the control group (non-tailored generic advice). In all three conditions participants were asked to fill in the baseline questionnaire based on the I-Change model. The questionnaire assessed socio-demographics, attitude towards smoking, knowledge, self-efficacy, social influence, depression, level of addiction, action planning, goal actions, intention to quit smoking, seven-day point prevalence and continued abstinence. Follow-up measurements were conducted at six and twelve months after baseline.
    Discussion: The present paper describes the development of the two computer-tailored smoking cessation
    programs, their components and the design of the study. The study results reveal different working mechanisms of
    multiple tailored smoking cessation interventions and will help us to gain more insight into effective strategies to
    target different subgroups, especially smokers with a lower socio-economic status.
