Background and study aims
This research project aims to understand how many grade 11 students in Muscat, Oman, use tobacco and vape, and what factors influence these behaviors. It also aims to test a school-based program designed to help students quit smoking.

Who can participate?
Grade 11 students from schools in A Seeb area of Muscat can participate in the first part of the study. Students identified as smokers from the first part will be invited to participate in the second part.

What does the study involve?
In the first part, students will take part in face-to-face interviews conducted by school health nurses using a survey from the World Health Organization. In the second part, students who smoke will receive monthly counseling sessions for four months to help them quit smoking.

Health condition(s) or problem(s) studiedMotivational Interviewing counselling for smoking cessation
InterventionFor study 1: a cross-sectional study in which structured face-to-face interview (survey) will be conducted by trained school health nurses utilizing the World Health Organization (WHO) Global Youth Tobacco Survey (GYTS) questionnaire, including data on the demographics, behavioral intentions, attitudes, subjective norms and perceived behavioral control on smoking (constructs of the Theory of Planned Behavior - TPB). A representative sample (n=886) from all schools of A Seeb area in Muscat, the capital of Oman, will be included (12 x schools). Logistic regression models will be done to determine factors associated with tobacco use and change in the constructs of the TPB. A team from the Ministry of Health and Education will be trained on project objectives, measurement tools, recruitment procedures, and data collection.

For study 2, a pilot quasi-experimental single arm pre- and post-study will be used (n=28, students identified as smokers from study 1). School health nurses (n=12) will be trained to deliver the behavior change intervention monthly for 4 months. School nurses will deliver monthly school-based interventions to the students over 4 months. The monthly intervention is composed of a 30-40 minutes counselling session guided by Motivational Interviewing (MI) strategies widely used for adolescent smoking cessation. Motivational interviewing (MI) is a brief, client-centered approach focused on resolving doubts regarding quitting and increasing self-efficacy for change.
