<b>Supporting data for "Effectiveness of telephone counseling and instant messaging support guided by mHealth profiling of smokers for smoking cessation: a randomized controlled trial"</b>

<p dir="ltr">The utilization of smoking cessation aids is low. This research aimed to assess the effectiveness of a novel mobile health (mHealth) profiling via ecological momentary assessment (EMA) in personalizing smoking cessation intervention for smokers who had no intention to use smoking cessation services and medications.</p><p dir="ltr">This thesis used both quantitative and qualitative data from this research.</p><p dir="ltr">Quantitative data were collected at baseline, during a 7-day EMA period, and at 3- and 6-month follow-ups. Baseline data included sociodemographic characteristics and smoking patterns. Follow-ups at 3 and 6 months also included smoking patterns. Smoking patterns included the types of tobacco products used, previous quit attempts, readiness to quit, nicotine dependence level, self-efficacy in quitting, and incremental behavior change towards smoking (IBC-S). Participant evaluations and engagement with the intervention were recorded at the 3-month follow-up. Additionally, quit attempts, usage of smoking cessation services, usage of smoking cessation medications, and biochemically validated tobacco abstinence were also collected at both 3- and 6-month follow-ups. Participants' smoking behaviors, including smoking, tobacco craving, and purchase of tobacco products, as well as their corresponding triggers, were collected five times per day for seven consecutive days during the 1-week EMA period.</p><p dir="ltr">For qualitative data, we interviewed some participants to explore their experiences and perceptions of the EMA and personalized mHealth interventions.</p>
