This study reviewed randomised controlled trials (RCTs) investigating the effectiveness of text message-based interventions for smoking cessation. The analysis included the effects of dose (number of text messages) and concomitant use of behavioural or pharmacological interventions.
30 of the 40 included studies reported higher rates of smoking cessation among those receiving text messaging interventions. However, only 10 of the reported improvements were statistically significant. A meta-analysis of seven RCTs found that participants receiving text messages were significantly more likely to quit smoking compared with participants in no/minimal intervention or 'usual care' conditions. Three trials found no benefit from a higher dose of text messages on smoking cessation. Two trials that tested the added benefit of text messaging to pharmacotherapy reported outcomes in favour of adding text messaging. |
