Do school-based smoking preventive interventions have unintended effects? Post hoc analysis of the Focus cluster randomised controlled trial

OBJECTIVES

Public health interventions are designed to improve specific health-related outcomes; however, they may also produce negative side effects, such as substitution use, psychological or social harms. Knowledge about the unintended effects of school-based smoking preventive interventions is sparse. Hence, this study examined these potential unintended effects of the smoking-reducing intervention, Focus, among students in the vocational education and training setting.

DESIGN

Cluster randomised controlled trial stratified by school type with 5 months follow-up.

SETTING AND PARTICIPANTS

Across Denmark, eight schools were randomised to the intervention group (n=844 students, response proportion 76%) and six schools to the control group (n=815 students, response proportion 75%). This study focused solely on students who smoked at baseline (N=491).

INTERVENTIONS

The intervention was developed systematically based on theory and a thoroughly mixed-methods needs assessment. Intervention components included a comprehensive school tobacco policy (smoke-free school hours) supported by a 3-day course for school staff and launched by an edutainment session for students; class-based lessons and a quit-and-win competition; and individual telephone smoking cessation support.

OUTCOMES

Alternative tobacco and nicotine products (regular use of smokeless tobacco, hookah and e-cigarettes), regular cannabis use, boredom and loneliness at school, stress and perceived stigmatisation among smokers.

RESULTS

We found no statistically significant unintended effects of the intervention. Nonetheless, insignificant findings indicated that students in the intervention group were less likely to be bored during school hours (OR 0.59, 95% CI 0.32 to 1.10) and experience stress (OR 0.62, 95% CI 0.35 to 1.10), but more likely to report feeling stigmatised compared with the control group (OR 1.55, 95% CI 0.71 to 3.40).

CONCLUSIONS

Overall, findings suggested no unintended effects of the Focus trial with respect to substitution use, psychological, nor group or social harms. Future research is encouraged to report potential harmful outcomes of smoking preventive interventions, and interventions should be aware of the possible stigmatisation of smokers.

Reducing smoking in youth by a smoke-free school environment: A stratified cluster randomized controlled trial of Focus, a multicomponent program for alternative high schools

Youth smoking remains a major challenge for public health. Socioeconomic position influences the initiation and maintenance of smoking, and alternative high school students are at particularly high risk. The school environment is an important setting to promote health, however there is a lack of evidence-based school intervention programs. This article presents the Focus study, which aims to test the implementation and effectiveness of a school-based intervention integrating¹ a comprehensive school smoking policy [i.e. smoke-free school hours (SFSH)]², a course for school staff in short motivational conversations³, school class-based teaching material⁴, an edutainment session5, a class-based competition, and6 access to smoking cessation support. Together these intervention components address students' acceptability of smoking, social influences, attitudes, motivation, and opportunities for smoking. The setting is alternative high schools across Denmark, and the evaluation design is based on a stratified cluster randomized controlled trial comparing the intervention group to a control group. Outcome data is collected at baseline, midway, and at the end of the intervention period. Moreover, a detailed process evaluation, using qualitative and quantitative methods, is conducted among students, teachers, and school principals. The results from this trial will provide important knowledge on the effectiveness of a smoke-free school environment. The findings will lead to a better understanding of which policies, environments, and cognitions, contribute to preventing and reducing cigarette use among young people in a diverse and high-risk school setting, and illuminate which complementary factors are significant to achieve success when implementing SFSH.

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.

School Coordinators' Perceptions of Organizational Readiness Is Associated with Implementation Fidelity in a Smoking Prevention Program: Findings from the X:IT II Study

School organizational readiness to implement interventions may play an important role for the actual obtained implementation level, and knowledge about organizational readiness prior to intervention start can help pinpoint how to optimize support to the schools. In this study, we applied a novel heuristic, R = MC2 to assess school organizational readiness prior to implementation of a multicomponent smoking prevention program. Furthermore, we examined the association to actual implementation after the first year of study. We used questionnaire data from school coordinators at 40 schools in Denmark who had accepted to implement the multi-component smoking prevention intervention-X:IT II-in the school year 2017-2018 including three main components: (1) Rules on smoke-free school time, (2) A smoke-free curriculum, and (3) Parental involvement. On behalf of the school, a school coordinator answered a baseline questionnaire about the organizational readiness and a follow-up questionnaire about implementation of the three components after first year of study. Readiness was measured by summing aspects of motivation (relative advantage, compatibility, complexity, and priority), general capacity (culture, climate, and staff capacity), and innovation-specific capacity (knowledge, skills, and abilities). Based on school coordinators' perceptions, almost all schools had good general capacity while the other two areas of readiness varied across schools; overall, 56.8% of schools (N = 25) had good motivation for implementing the X:IT II intervention and 61.3% (N = 27) had high innovation-specific capacity. Half of the schools had high overall readiness defined as high motivation and high innovation-specific capacity. Schools with high overall readiness implemented the rules on smoke-free school time, smoke-free curriculum, and parental involvement to a higher degree than schools with low overall readiness. All participating schools possessed sufficient levels of general capacity, e.g., a well-functioning organizational culture and sufficient staff capacity. High levels of motivation and innovation-specific capacity were positively associated with the schools' actual implementation of the main intervention components. This way of conceptualizing and measuring organizational readiness may be useful in future studies, i.e., in studies where enhancing readiness is a main objective.

The Effect of Peer Education on Decision-Making, Smoking-Promoting Factors, Self-Efficacy, Addiction, and Behavior Change in the Process of Quitting Smoking of Young People

Purpose

The study aims to examine the effect of peer education on the decision to quit smoking, factors that encourage smoking, self-efficacy, addiction, and behavior change in students who apply to the Youth Friendly Center to quit smoking.

Participants and Methods

This research is a Randomized Controlled Trials study. The experimental group consisted of students who were enrolled in the peer education course (n=759). The control group has consisted of students (n=1095) who did not enroll in this course.

Results

Participants in the experimental group to quit smoking, more than the control group (p>0,01). The addiction level of the participants in the experimental group, less than the participants in the control group (p>0,01). According to the scores of the participants in the control group of the participants in the experimental group, the factors that trigger smoking, and the benefit sub-dimension scores in the Decision Balance Scale were low. Loss sub-dimension scores, which show the losses from the harms of smoking, increased significantly in the Self-Efficacy Scale, Behavior Change Process Scale, and Decision Balance Scale (p>0,01).

Conclusion

Peer educators trained by the researcher and her team in the Youth Friendly Center Smoking Quit Program have an important effect in supporting/improving the cognitive and behavioral change processes of university students in smoking quit compared to those who do not receive an education. 94% success of the smoking quit program; Students’ voluntary application to receive professional support, students’ voluntary attendance of the treatment program for 6 months, strong communication and feedback, effective and functional professional counseling, and social support depend on strengthening the program with peer education. Especially with peer education, the development of leadership and role model characteristics made the smoking quit program preferred by students.

Programme theory and realist evaluation of the 'Smoke-Free Vocational Schools' research and intervention project: a study protocol

INTRODUCTION

Smoke-free school hours (SFSHs) entails a smoking ban during school hours and might be an effective intervention to reduce the high smoking prevalence in vocational schools. For SFSH to be effective, the policy must be adequately implemented and enforced; this challenge for schools constitutes a research gap. The 'Smoke-Free Vocational Schools' research and intervention project has been developed to facilitate schools' implementation of SFSH. It is scheduled to run from 2018 to 2022, with SFSH being implemented in 11 Danish vocational schools. This study protocol describes the intervention project and evaluation design of the research and intervention project.

METHODS AND ANALYSIS

The intervention project aims to develop an evidence-based model for implementing SFSH in vocational schools and similar settings. The project is developed in a collaboration between research and practice. Two public health NGOs are responsible for delivering the intervention activities in schools, while the research partner evaluates what works, for whom, and under what circumstances. The intervention lasts one year per school, targeting different socioecological levels. During the first 6 months, activities are delivered to stimulate organisational readiness to implement SFSH. Then, SFSH is established, and during the next 6 months, activities are delivered to stimulate implementation of SFSH into routine practice. The epistemological foundation is realistic evaluation. The evaluation focuses on both implementation and outcomes. Process evaluation will determine the level of implementation and explore what hinders or enables SFSH becoming part of routine practice using qualitative and quantitative methods. Outcomes evaluation will quantitively assess the intervention's effectiveness, with the primary outcome measure being changes in smoking during school hours.

ETHICS AND DISSEMINATION

Informed consent will be obtained from study participants according to the General Data Protection Regulation (GDPR) and Danish data protection law. The study adheres to Danish ethics procedures. Study findings will be disseminated at conferences and further published in open-access peer-reviewed journals.

Estimating future smoking in Danish youth – effects of three prevention strategies

Aims: Preventing smoking and aiding cessation among youth and young adults carries the possibility of reducing future smoking prevalence significantly. This paper estimates the impact on future smoking prevalence of 25 year olds by increasing tobacco prices, securing indoor smoke-free homes and implementing school-based multi-tiered interventions. Methods: Utilizing a multi-state Markov model, a status quo projection of the smoking prevalence from years 2017 to 2030 were compared with projections of the smoking prevalence in 2030 considering the impact of the three prevention strategies. Results: In a status quo projection, 27.0% of Danish 25-year-old females are expected to be smokers in 2030, while 13.2% would be smokers in 2030 were all three prevention strategies in effect from 2019. By itself, increasing tobacco prices by 50% reduced the prevalence of smokers among 25-year-old females to 14.8% in 2030, a relative reduction of 47.5%. For 25-year-old males in 2030 the reductions were similar, with a prevalence of 16.6% when all three prevention strategies were in effect, a relative reduction of 51.5%. Conclusions: Implementing increasing tobacco prices, indoor smoke-free homes and school-based multi-tiered interventions in Denmark is likely to significantly decrease youth smoking prevalence in the future. However, these three strategies will not produce a smoke-free generation without other initiatives.

Associations of school tobacco policies and legislation with youth smoking: a cross-sectional study of Danish vocational high schools

BACKGROUND

In vocational high schools, the prevalence of smoking is high (nearly 40% daily smoking in Danish vocational high schools). Schools are increasingly adopting school tobacco policies (STPs) and a national law on smoke-free school grounds has been implemented. Our objective was to explore the extent of STPs in vocational schools and examine the association of STPs and smoke-free school grounds legislation with student smoking.

METHODS

We used data from the cross-sectional Danish National Youth Study 2014, including 5013 vocational high school students (76% male) at 40 campuses. Implementation of STPs was measured by questionnaires to principals and field observations of smoking practices were conducted. Logistic regression models assessed whether STP characteristics were associated with students' current smoking (ie, daily and occasional) compared with non-current smoking. Negative binominal regression models assessed cigarettes per day among daily smokers.

RESULTS

Schools covered by the national law on smoke-free school ground had more comprehensive STPs than schools not covered by the law. Student smoking was observed on 78% of campuses, with less visibility of smoking in schools covered by the national law (69% vs 83%). Current smoking was lower for students attending a school covered by the national law (OR=0.86, 95% CI 0.75 to 0.97). Students who attended schools that allowed teacher-student smoking were more likely to smoke (OR=1.13, 95% CI 1.01 to 1.27).

CONCLUSIONS

A law on smoke-free school grounds was associated with less current smoking in vocational high schools, while school norms that are supportive of teacher-student smoking were associated with greater odds of current smoking. Visibility of student smoking was less prevalent at schools covered by the law on smoke-free school grounds; nevertheless, the visibility of smoking was high. Better enforcement or an extension of the current law on smoke-free school grounds is recommended.

Smoke-free-school-hours at vocational education and training schools in Denmark: attitudes among managers and teaching staff - a national cross-sectional study

BACKGROUND

Tobacco is the main cause of non-communicable disease and premature death globally. Implementing restrictive school tobacco policies such as smoke-free-school-hours (SFSH) may have the potential to reduce smoking among Vocational Education and Training (VET) school students. To be effective, school tobacco policies that largely involve strict and consistent enforcement by both managers and teaching teaching staff must be implemented. This study investigated the attitudes towards the implementation of SFSH among the managers and teaching staff at Danish VET schools.

METHODS

The analyses were based on cross-sectional survey data collected with an online survey among managers and teaching staff at Danish VET schools. The data was collected from March to June 2017.

RESULTS

Managers and teaching staff (n = 571) from 71 out of 87 Danish VET schools (81.6%) took part in the survey. In the adjusted analysis, teaching staff were twice as likely as managers to have a favourable attitude towards SFSH. Furthermore, being female and of increasing age correlated with having a favourable attitude. A trend towards schools in favour of SFSH having more health promotion facilities, policy and practice, was identified.

CONCLUSION AND IMPLICATIONS

Existing health promotion facilities and activities at the schools were associated with a favorable attitude among the management towards implementing SFSH. Thus, implementing other health promotion activities and policies might be an important first step to establish readiness to implement SFSH.
