Outcome Measures

Primary Outcomes (1)

  • Repeated Use of website measure

    This measure is an ordinal scale of the number of functions used after the first visit to the Decide2Quit.org website (0: use of no functions, 1: use of 1-2 functions, 2: use of 2-4 functions, see Table 9 list of functions). We will use scripts on the website to assess this information

    Every Login for 6 months

Secondary Outcomes (1)

  • 30-day point prevalent smoking cessation at six months

    At 6 months

Study Arms (2)
