Objective:
This study sought to develop a WeChat mini-program for smoking cessation behavioral interventions (named the WQ mini-program) and evaluate its usability, acceptability, and preliminary efficacy among Chinese smokers.
Methods:
The WQ mini-program was designed based on behavioral change theories and clinical practice guidelines, and clinical smoking cessation experts participated in the development process. Fifty Chinese smokers and five software experts were involved in a single-arm trial. Smokers were asked to use the WQ mini-program at least once a day for 4 weeks and to complete a weekly online follow-up questionnaire. Software experts were asked to complete an online follow-up questionnaire after using all functions of the WQ mini-program. Primary outcomes were usability and acceptability of and satisfaction with the mini-program tested by the System Usability Scale (SUS) and the Mobile App Rating Scale (MARS). Self-reported 7-day point prevalence abstinence (PPA) was used to evaluate its preliminary efficacy for smoking cessation. Optimization suggestions for the mini-program were collected from all participants through an open-ended question at the last follow-up and were analyzed by thematic analysis.
Results:
The mean SUS and MARS total scores for the WQ mini-program as evaluated by smokers were 82.1 ± 13.8 and 84.5 ± 3.3 and by software experts were 4.21 ± 0.32 and 4.27 ± 0.15, respectively. Most smokers reported being willing to recommend this mini-program to other smokers (85.4%) and would continue to use it (95.8%). The mean satisfaction score for the mini-program was 4.23 ± 0.69 (out of 5 points) among smokers. Self-reported 7-day PPA among smokers at the 4-week follow-up was 50% (25/50).
Conclusions:
This study demonstrated that the WQ mini-program would be a feasible and potentially effective method to encourage Chinese smokers to quit smoking. However, future research is needed to confirm its efficacy through a randomized controlled trial.

Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
