Randomized Controlled Trial
'Someone batting in my corner': experiences of smoking-cessation support via text message.
The txt2stop trial demonstrated that smoking-cessation support delivered by text message doubles biochemically verified abstinence at 6 months. There was no significant heterogeneity in any of the pre-specified subgroups. ⋯ Although the intervention did stimulate craving in some participants at some times, recipients reported that it also provided emotional support and reinforcement at temporally appropriate moments. It was successful at helping people to quit smoking but could be used together with other forms of smoking-cessation support.
