Brief summary

In 2012, we conducted a review of free smoking cessation apps in the Apple store and Android market and found that all 130 apps lacked the informational content about smoking which is necessary to help quit. For instance, none of the identified apps provided information about evidence-based treatment (Not published). In phase 1 of this study, we found that of 394 participants, 43% have used smoking cessation apps before, and of them 55% have made a quit attempt using an app. Given that most of the available apps are not of a high quality, our aim is to develop an evidence-based decision aid smartphone app, to help smoker decide on the best available quitting method suitable for them, and follow up their quitting process. The intervention and control apps will be compared in terms of helping participants making quitting attempts and abstinence rate at 4 time-points (10 days, 1 month, 3 months, and 6 months).

Interventions

The intervention app includes compulsory information (participants cannot move to the next step before confirming if they have read the provided information and they will be asked if they read all the information, read some of the information, haven’t read anything) about quitting methods and optional information about smoking consequences, multiple compulsory advanced notifications at different stages of the quitting process e.g. at the selected quitting date and daily motivational notificatio

The intervention app includes compulsory information (participants cannot move to the next step before confirming if they have read the provided information and they will be asked if they read all the information, read some of the information, haven’t read anything) about quitting methods and optional information about smoking consequences, multiple compulsory advanced notifications at different stages of the quitting process e.g. at the selected quitting date and daily motivational notifications. In addition, the app will motivate participants to write quitting diaries (e.g. craving triggers). After reviewing the interventions user will be asked if they are willing to quit in and what of the provided options they are willing to use, and then follow how they act on their decision at 4 time-points (10 days, 1 month, 3 months, and 6 months). The participants in both groups will be advised to complete reading the provided information in the first 3 days and setup a quit date within the next 7 days. Participants in the intervention group will be advised to use the app regularly after quitting benefit from the self-help functions. The app will be available for the participants in the intervention group for 6 months, after this period the app will automatically stop the data collection and participants can use it as long as they want. The app will monitor the daily usage data including, number of times the participant open the app, and record the number of times the participants looked at or used any function.
