Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A behavioural faith-based intervention for smoking cessation. The intervention consists of religious-based messages and health messages. The messages were informed by qualitative interviews with current and former Muslim smokers and co-designed with religious scholars. The intervention will be text-message-based; each text message will be less than 500 words. The health messages include providing information on the harm of smoking, the benefits of quitting, and strategies to overcome cravings. The health messages are supported by religious messages from the Quran (Islami holy book) and Hadith (Prophet Mohammed's teachings). Participants will receive daily text messages during Ramadan 2024 (over 30 days) and one month post-Ramadan. In the first 15 days of Ramadan, participants will receive two messages per day. In the last 15 days, they will receive one message per day. After Ramadan, participants will receive three weekly messages for four weeks to enhance smoking cessation support. To monitor protocol adherence, participants will be sent a weekly questionnaire asking if they read the messages.
Intervention code [1] 327730 0
Behaviour
Comparator / control treatment
The control group will receive text messages about health and behaviour change techniques not supported by religious messages. Each message will be less than 300 words. The messages will be drawn from the literature on smoking cessation behaviour change techniques and the txt2stop messaging library, including information on the harm of smoking, the benefits of quitting, and strategies to overcome cravings. Similar to the intervention group, the control group will receive daily text messages during Ramadan 2024 (over 30 days) and one month post-Ramadan. In the first 15 days of Ramadan, participants will receive two messages per day. In the last 15 days, they will receive one message per day. After Ramadan, participants will receive three weekly messages for four weeks to enhance smoking cessation support. To monitor protocol adherence, participants will be sent a weekly questionnaire asking if they read the messages.
