Factors influencing the overall satisfaction of teachers participating in a nationwide school-based smoking prevention program in Korea.

Introduction: Numerous studies of school-based smoking prevention programs (SSPPs) exist; however, most have been conducted from the students' perspective, and insufficient research has explored teachers' perceptions. Our study aimed to identify factors affecting overall satisfaction and operational status from the perspective of teachers participating in the SSPP.

Methods: This is a cross-sectional study analyzing data from a survey regarding the operation of an SSPP conducted by the Korea Health Promotion Institute in 2022. The study sample comprised 669 teachers involved in the SSPP: 215 from elementary schools, 212 from middle schools, and 242 from high schools. To identify factors influencing teachers' overall satisfaction, independent variables were categorized into three types of factors: personal, school, and teacher perceptions. Multiple linear regression analysis was performed for each factor to test the independent association.

Results: For elementary school teachers, as the necessity of smoking prevention and cessation education (β=0.292; 95% CI: 0.182-0.382) increased, the overall satisfaction with the operation of the SSPP significantly improved. Similarly, for middle school teachers, as the necessity of smoking prevention and cessation education (β=0.231; 95% CI: 0.104-0.336) increased, the overall satisfaction significantly improved. Conversely, for high school teachers, the effectiveness (β=0.347; 95% CI: 0.184-0.520) was the variable that significantly improved overall satisfaction with the SSPP operation. The variables affecting teacher satisfaction across all school levels were the necessity of smoking prevention and cessation education, the effectiveness of the SSPP, and its impact on smoking cessation among smoking students, all of which belonged to the teacher perceptions factor.

Conclusions: Smoking education in schools requires teachers to play a crucial role. Among participating teachers, overall satisfaction with SSPP operations and the influencing factors differed according to school level, highlighting the importance of careful consideration to establish a more effective operational environment tailored to each school level.
