Intervention Activities Associated with the Implementation of a Comprehensive School Tobacco Policy at Danish Vocational Schools: A Repeated Cross-Sectional Study

School tobacco policies are often poorly implemented, which may explain their limited effectiveness. Further, constructs to measure implementation outcomes of school tobacco policies are missing. The Smoke-Free Vocational Schools intervention was designed to stimulate the implementation of a comprehensive school tobacco policy into routine practice. This study (1) developed implementation fidelity outcomes measures for the school tobacco policy and (2) examined associations between intervention activities and implementation fidelity at two time points. We applied a repeated cross-sectional survey study design across seven schools: the first time point was >5 months after the policy was established and the second time point > 14 months after policy establishment. The dependent/outcome variables were four binary fidelity domains as well as a total score across domains. A total of six intervention activities were measured among either students (e.g., new school-break facilities) or staff/managers (e.g., a joint workshop before policy implementation). Associations were analyzed separately for students and staff/managers using generalized linear mixed models, adjusted for confounders. A total of n = 2674 students and n = 871 staff/managers participated. The total implementation fidelity scores increased over time among both students and staff/managers. Three intervention activities were consistently associated with the total implementation fidelity score, including: new school-break facilities (B_T1 = 0.08, 95% CI = 0.03; 0.12; B_T2 = 0.07, 95% CI = 0.04-0.50), the joint workshop before policy implementation (B_T1 = 0.13, 95% CI = 0.02; 0.25; B_T2 = 0.13, 95% CI = 0.004; 0.24), and internalization of fixed procedures for enforcement (B_T1 = 0.19, 95% CI = 0.13-0.26; B_T2 = 0.16, 95% CI = 0.13-0.26). These findings can be applied by schools and other actors in practice. The developed implementation fidelity outcomes measures can be applied in future research on school tobacco policies.

Are Danish vocational schools ready to implement "smoke-free school hours"? A qualitative study informed by the theory of organizational readiness for change

BACKGROUND

The smoking prevalence is high among students enrolled in vocational education and training, which is considered a lower level of education. The school tobacco policy regarding smoke-free school hours stipulates that students and staff are not allowed to smoke during school hours-inside or outside school premises-and it might be an effective intervention for reducing smoking in vocational schools. For school tobacco policies to be effective, they must be appropriately implemented. A primary predictor for successful implementation is organizational readiness for change. This study seeks to identify and understand the barriers to and facilitators for developing organizational readiness to implement smoke-free school hours in Danish vocational schools.

METHODS

Semi-structured interviews and focus groups were carried out with managers and teachers (n = 22 participants) from six vocational schools. The interview guides were informed by "A theory of organizational readiness for change" developed by Weiner, which was also used as a framework to analyze the data.

RESULTS

We identified 13 facilitators and barriers. Nine factors acted as facilitators, including the following: believing that health promotion is a school role and duty; believing that society and workplaces are becoming more smoke-free, and believing that smoke-free school hours is a beneficial strategy to achieve fewer educational interruptions. Additional facilitators include establishing clear rules for sanctioning and enforcement, developing a joint understanding about smoke-free school hours, developing skills to deal with student responses to smoke-free school hours, establishing social alternatives to smoking, offering smoking cessation help, and mandating smoke-free school hours by law. Four organizational norms, practices, or discourses acted as barriers: believing that smoke-free school hours violate personal freedom, believing that students have more important problems than smoking, believing that it is difficult to administer the level of enforcement, and believing that the enforcement of smoke-free school hours negatively influences student-teacher relations.

DISCUSSION

Our results suggest that developing organizational readiness before adopting a comprehensive tobacco policy such as smoke-free school hours is important for successful implementation. Further research should investigate how to strengthen the facilitators for and counter the barriers to developing readiness for implementing smoke-free school hours.
