Abstract
To estimate the effect of a 3-year commitment to remain tobacco free on tobacco uptake among high school students in Sweden. The commitment is developed in the form of a contract between a child and a significant adult, constituting the core component of Tobacco-free Duo (T-Duo), a Swedish school-based tobacco prevention program. Secondary analysis of data from a cluster randomized controlled trial. Participants were 586 students in high schools assigned to the intervention arm of T-Duo. At inception, participants attended grade 7 (i.e., age 12-13). Only students who were tobacco naïve at baseline for the respective outcome and participated in all follow-ups were included. The exposure was defined as signing a 3-year contract with a significant adult, categorized as "stable contract" (3 years contract with the same contract partner), "unstable" (signed a contract sometime during follow-up but this was not sustained over time and/or with the same partner), and "no contract" at all during the intervention period. The primary outcome was having never tried cigarette smoking at the end of grade 9. Exposure and outcomes were self-reported in yearly questionnaires. Of 586 students, 321 (55%) held a stable contract, 204 (35%) an unstable contract, and 61 (10%) did not sign a contract at all. At the end of grade 9 (age 15-16), the relative risk (RR) to remain cigarette free was 1.11 (95% CI 1.00-1.22) (Number Needed to Treat = 10) among students in any type of contract compared to students that did not write a contract at all. The RRs for remaining tobacco free (secondary outcomes) ranged from 1.07 (0.98-1.16) for regular snus use to 1.16 (1.00-1.35) for any type of tobacco use. A commitment to remain tobacco free through a child-adult contract seems to exert a preventive effect on the uptake of tobacco use among Swedish adolescents over 3 school years. The current findings apply to a selected sample of both schools and students. Registration: Current Controlled Trials ISRCTN52858080 Date: January 4, 2019, retrospectively registered.

Abstract
INTRODUCTION The study aimed to assess the impact of a new intervention proposal involving students, teachers, and parents on smoking prevalence in secondary school adolescents. METHODS A quasi-experimental study was conducted, in which the response to a preventive multi-personal intervention model (intervention) against tobacco consumption was compared with a standard anti-smoking activity carried out by the local government administration (control). The study was carried out during the 2017-2018 academic year. The study population included 306 students (intervention 151, control 155) with a mean age of 13.4 years. The model involved the parents, the students (aged 15-17 years), and the teachers. The primary outcome was the change in smoking status one year after the intervention. RESULTS The percentage of non-smokers increased from 84.1% to 88.7% in the intervention group and remained almost unchanged among controls (89.3% vs 89.9%). After one year, there was an increase in the prevalence of non-smokers of 4.6% and a decrease in the prevalence of smokers of 4.7% among students who received the multi-personal intervention, whereas changes among controls were almost negligible (there was in fact a slight increase in the prevalence of smokers of 0.9%). The students who received the intervention smoked less or quit smoking more than those in the control group (OR=0.135; 95% CI: 0.019-0.973, p=0.047). CONCLUSIONS The multi-personal model developed in the study with the participation of teachers and parents focused on students was feasible, and effectively reduced the prevalence of smoking among high school adolescents.

Systematic review of intervention functions, theoretical constructs and cultural adaptations of school-based smoking prevention interventions in low-income and middle-income countries. BMJ Open 2023; 13:e066613.

Abstract
OBJECTIVE To identify the approaches and strategies used for ensuring cultural appropriateness, intervention functions and theoretical constructs of the effective and ineffective school-based smoking prevention interventions that were implemented in low-income and middle-income countries (LMICs). DATA SOURCES Included MEDLINE, EMBASE, Global Health, PsycINFO, Web of Science and grey literature which were searched through August 2022 with no date limitations. ELIGIBILITY CRITERIA We included randomised controlled trials (RCTs) with ≥6 months follow-up assessing the effect of school-based interventions on keeping pupils never-smokers in LMICs; published in English or Arabic. DATA EXTRACTION AND SYNTHESIS Intervention data were coded according to the Theoretical Domains Framework, intervention functions of Behaviour Change Wheel and cultural appropriateness features. Using narrative synthesis we identified which cultural-adaptation features, theoretical constructs and intervention functions were associated with effectiveness. Findings were mapped against the capability-motivation and opportunity model to formulate the conclusion. Risk of bias was assessed using the Cochrane risk of bias tool. RESULTS We identified 11 RCTs (n=7712 never-smokers aged 11-15); of which five arms were effective and eight (four of the effective) arms had a low risk of bias in all criteria. Methodological heterogeneity in defining, measuring, assessing and presenting outcomes prohibited quantitative data synthesis. We identified nine components that characterised interventions that were effective in preventing pupils from smoking uptake. These include deep cultural adaptation; raising awareness of various smoking consequences; improving refusal skills of smoking offers and using never-smokers as role models and peer educators. CONCLUSION Interventions that had used deep cultural adaptation which incorporated cultural, environmental, psychological and social factors, were more likely to be effective. Effective interventions considered improving pupils' psychological capability to remain never-smokers and reducing their social and physical opportunities and reflective and automatic motivations to smoke. Future trials should use standardised measurements of smoking to allow meta-analysis in future reviews.

Abstract
Several studies demonstrated that electronic media use (EMU) is negatively associated with sleep in adolescents. Most studies however are cross-sectional, self- or parents reports, and not distinguishing between different EMU types. Therefore, this study aimed to examine associations between adolescent's EMU and sleep reported by adolescents and from their mothers' perspective in a dyadic ambulatory assessment design. One hundred and five mother-adolescent dyads reported for 14 consecutive days adolescent's EMU for different EMU types and sleep duration. Mothers reported less EMU in the evening and more sleep of their adolescents than adolescents themselves. Multilevel analyses revealed that at the between- and within-person level, EMU in the evening was negatively associated with sleep. Different EMU types differed in effect sizes of associations with sleep. No effects were found for watching TV/DVD/video, whereas for gaming at the between- and within-person level, negative associations with sleep duration were found. For PC/tablet and smartphone use in the evening significant between-person association with sleep duration for adolescent's self-reports and from mother's point of view was found. It is important to investigate adolescent's EMU on a daily basis, from a dyadic perspective, and for different EMU types separately.

Abstract
BACKGROUND: Stronger family connections, communications, and parental respect reduce smoking initiation. Web-based computer-tailored smoking prevention programs may help decrease smoking initiation rates among adolescents. However, there is currently no conclusive evidence regarding the efficacy of a web-based, computer-tailored smoking prevention program to empower families in adolescent smoking prevention.
AIM: This study aimed to investigate the effects of web-based education program to empower family, improve skill to refuse, and prevent smoking initiation among adolescent in Indonesia.
METHODS: A randomized controlled trial was employed on family members in Bogor, West Java, Indonesia. The following criteria were the mother or legal guardian of children aged 10 to 14 years who are not currently smoking. Data were collected 3 times: One week before the start of the training (baseline), immediately after intervention (T1), and three months after the training concluded (T2).
RESULTS: 77 participants completed the study, 37 in the intervention group and 40 in the control group. The average age in this sample of the family (mother) was 37.34 (SD:7.51) years in the intervention group and 11.75 (SD:6.81) for the control group. From baseline to follow-up, family empowerment, smoking refusal skill, and smoking intention increased 38%, 24%, and 33%, respectively.
CONCLUSIONS: A web-based education program appears to be a suitable catalyst for empowering family and smoking prevention among adolescents. It should be regarded as a valuable and supportive addition to existing and future programs.

Abstract
Friends' and parents' tobacco use are strong predictors of tobacco uptake among adolescents, however the effectiveness of interventions based on public commitments and agreements to remain tobacco-free are not established. Here, we evaluated the effectiveness of the school-based Swedish program Tobacco-Free Duo (T-Duo) in preventing adolescents from initiating tobacco use (TOPAS study). T-Duo is a multi-component intervention witha formal agreement between a student and an adult partner to remain tobacco-free during the entire 3-year study period as core component. The standardized educational component of the same program was used as comparator (control). Primary outcome was the probability to "remain a non-user" of i) cigarettes and secondary outcomes ii) other types of tobacco at second (21-month) follow-up. Analysis was conducted according to Intention To Treat. In total 1776 adolescents (51% female) aged 12-13 in grade 7 from 34 participating high schools in Sweden were included at baseline in 2018, of which 1489 were retained after 21 months. The Risk Ratio (RR) of not having tried cigarettes 21-months after initiation of the intervention was 1.03(CI 0.98-1.08), Bayes Factor(BF) = 0.93, Absolute Risk Difference(ARD) = 3.1%. Similar associations were found for never smoked a whole cigarette and never use of other tobacco/nicotine products. There was a minimal reduction of tobacco use initiation among Swedish adolescents assigned to a multi-component intervention (T-Duo) compared to those assigned to standardized classroom education after 2 schoolyears. However, for most outcomes' findings were inconclusive and not reliably different from zero.

Abstract
Each day, adolescents and young adults (AYAs) choose to engage in behaviors that impact their current and future health. Behavioral economics represents an innovative lens through which to explore decision-making among AYAs. Behavioral economics outlines a diverse set of phenomena that influence decision-making and can be leveraged to develop interventions that may support behavior change. Up to this point, behavioral economic interventions have predominantly been studied in adults. This article provides an integrative review of how behavioral economic phenomena can be leveraged to motivate health-related behavior change among AYAs. We contextualize these phenomena in the physical and social environments unique to AYAs and the neurodevelopmental changes they undergo, highlighting opportunities to intervene in AYA-specific contexts. Our review of the literature suggests behavioral economic phenomena leveraging social choice are particularly promising for AYA health. Behavioral economic interventions that take advantage of AYA learning and development have the potential to positively impact youth health and well-being over the lifespan.

Abstract
In Germany, alcohol is the most popular drug among adolescents. So far, school-based alcohol prevention programs have focused on elementary school children and pupils in early adolescence. The school program "Klar bleiben" ("Keep a Clear Head") was especially designed for young people in late adolescence (10th graders) with the aim of establishing non-binge drinking as a social norm.Students in the participating classes commit themselves to abstain from binge drinking for six weeks (contract management). The class gives feedback after each week. After at least five positive feedbacks, the class is rated as successful and enters a prize draw. Elaborated teaching impulses and information resources for teachers and parents are further components of the prevention program.The evaluation of the class competition by 92 teachers can be regarded as consistently positive. The results of a cluster-randomized study showed a relative risk reduction of 10.4% in binge drinking in the last month for those adolescents who had already consumed alcohol before and belong to the intervention group. After the end of the intervention, this group of adolescents consumed an average of 0.19 fewer alcoholic beverages per drinking occasion compared to adolescents from the control group. The findings presented here are encouraging, keeping in mind that the intervention is relatively inexpensive.

Abstract
BACKGROUND Universal tobacco-prevention programs targeting youths usually involve significant adults, who are assumed to be important social influences. Commitment not to use tobacco, or to quit use, as a formal contract between an adolescent and a significant adult is a preventive model that has not been widely practiced or explored and has been formally evaluated even less. In this paper, we present the rationale and protocol for the evaluation of the Swedish Tobacco-free Duo program, a multicomponent school-based program the core of which rests on a formal agreement between an adolescent and an adult. The adolescent's commitment mainly concerns avoiding the onset of any tobacco use while the adult commits to support the adolescent in staying tobacco free, being a role model by not using tobacco themselves. OBJECTIVE To assess (1) whether Tobacco-free Duo is superior to an education-only program in preventing smoking onset among adolescents and promoting cessation among their parents, (2) whether exposure to core components (adult-child agreement) entails more positive effects than exposure to other components, (3) the impact of the program on whole school tobacco use, (4) potential negative side effects, and (5) school-level factors related to fidelity of the program's implementation. METHODS A mixed-design approach was developed. First, a cluster randomized controlled trial was designed with schools randomly assigned to either the comprehensive multicomponent program or its educational component only. Primary outcome at the adolescent level was identified as not having tried tobacco during the 3-year junior high school compulsory grades (12-15 years of age). An intention-to-treat cohort-wise approach and an as-treated approach complemented with a whole school repeated cross-sectional approach was devised as analytical methods of the trial data. Second, an observational study was added in order to compare smoking incidence in the schools participating in the experiment with that of a convenience sample of schools that were not part of the experimental study. Diverse secondary outcomes at both adolescent and adult levels were also included. RESULTS The study was approved by the Umeå Regional Ethics Review Board (registration number 2017/255-31) in 2017. Recruitment of schools started in fall 2017 and continued until June 2018. In total, 43 schools were recruited to the experimental study, and 16 schools were recruited to the observational study. Data collection started in the fall 2018, is ongoing, and is planned to be finished in spring 2021. CONCLUSIONS Methodological, ethical, and practical implications of the evaluation protocol were discussed, especially the advantage of combining several sources of data, to triangulate the study questions. The results of these studies will help revise the agenda of this program as well as those of similar programs.

Abstract
BACKGROUND The subject of "Medical Psychology/Sociology" is facing various content changes as a result of the currently pending study reforms within the framework of the "Master Plan Medical Studies 2020". These include the further development of the catalogues of exam-relevant topics (GK) and the National Competence-Based Learning Objectives Catalogue for Undergraduate Medical Education (NKLM) as well as the Medical Licensing Regulations (ÄApprO). In this context, the question arises as to which training contents of "medical psychology/sociology", that medical students are confronted with, are of particular importance for their future medical work. METHODS 332 physicians and 265 students evaluated different contents of the catalogue of exam-relevant topics of medical psychology/sociology (GK-MPS) according to their importance regarding their education or respectively their daily work. In addition, the physicians indicated in free text fields of the questionnaire which situations in their daily work they would have liked to have been better prepared for during medical school. In a combined quantitative-qualitative analysis approach, differences between the 2 groups were identified by t-tests for independent samples with unequal variances (Welch test) and free text information was assigned to the various topics of the GK-MPS and evaluated in terms of content by 3 raters within the framework of a qualitatively oriented category-based text analysis. RESULTS Both physicians and students considered those topics of the GK-MPS, that involve communication between physician and patient, to be the most important. In addition, physicians rated the topics of physician-patient communication, statistics and prevention as more important than the students did. The physicians would have liked to have been better prepared for special and challenging medical situations in physician-patient interaction. DISCUSSION The topics of physician-patient communication are still considered to be of particular importance for the medical training of physicians and students, but physicians consider them to be more important than students. CONCLUSION The study results support the current study reforms towards a stronger emphasis on physician-patient communication and scientific basics as well as the linking of pre-clinical and clinical study contents.

Abstract
Background Inactive lifestyles are becoming the norm and creative approaches to encourage adolescents to be more physically active are needed. Little is known about how gamification techniques can be used in physical activity interventions for young people. Such approaches may stimulate interest and encourage physical activity behaviour. The study investigated the feasibility of implementing and evaluating a physical activity intervention for adolescents which included gamification techniques within schools. We tested recruitment and retention strategies for schools and participants, the use of proposed outcome measures, and explored intervention acceptability. Methods This school-based feasibility study of a randomised cluster trial recruited adolescents aged 12-14 years (n = 224) from five schools (three intervention; two control) in Belfast, Northern Ireland. The 22-week intervention (The StepSmart Challenge) informed by self-determination theory and incorporating gamification strategies involved a school-based pedometer competition. Outcomes, measured at baseline, and post-intervention (at 22 weeks post-baseline and 52 weeks post-baseline) included daily minutes of moderate to vigorous physical activity (MVPA) (measured using ActiGraph accelerometer), mental wellbeing (Warwick-Edinburgh Mental Wellbeing Scale), social support for physical activity, time preference (for delayed and larger rewards or immediate and smaller rewards), pro-social behaviour (Strengths and Difficulties Questionnaire (SDQ)) and the influence of social networks. The intervention's acceptability was explored in focus groups. Results We invited 14 schools to participate; eight showed interest in participating. We recruited the first five who responded; all five completed the trial. Of the 236 pupils invited, 224 participated (94.9%): 84.8% (190/224) provided valid MVPA (minutes/day) at baseline and 57.2% (123/215) at 52 weeks. All other outcomes were well completed apart from the SDQ (65% at baseline). Qualitative data highlighted that participants and teachers found The StepSmart Challenge to be an acceptable intervention. Conclusions The level of interest and high recruitment and retention rates provide support for the feasibility of this trial. The intervention, incorporating gamification strategies and the recruitment methods, using parental opt-out procedures, were acceptable to participants and teachers. Teachers also suggested that the implementation of The StepSmart Challenge could be embedded in a lifelong learning approach to health within the school curriculum. As young people's lives become more intertwined with technology, the use of innovative gamified interventions could be one approach to engage and motivate health behavioural change in this population.

Abstract
Introduction Arabic male adolescents have a high smoking prevalence. Introduction of "Class smoke-free" pledges have been successful amongst European adolescents but have not been evaluated using objective valid measures. We tested the impact of adding a smoke free pledge strategy to a proven peer-led asthma and smoking prevention program on breath carbon monoxide level (BCO) in male high-school students in Jordan. Methods We enrolled male students from four high-schools in Irbid, Jordan. Schools were randomly assigned to receive either TAJ (Triple A in Jordan, n = 218) or TAJ-Plus (with added class smoke-free pledge, n = 215). We hypothesized that students receiving TAJ-Plus would have greater reduction in BCO levels than those only receiving the TAJ intervention. Asthma and smoking status were assessed by self-administered questionnaires. Smoking outcomes were collected using a BCO Monitor. Results Both groups had significant reductions in BCO levels post-intervention (p < .0001), however, decreases were greater in TAJ-Plus group (3.9 ± 0.2 vs. 4.8 ± 0.2, p < .0001). Intervention effects on BCO over time did not vary by smoking status (p = .085), asthma status (p = .602), or a combination of the two (p = .702). Conclusions An added smoke-free pledge strategy to a proven peer-led asthma education program appears to be a promising approach to motivate adolescents to abstain from smoking in Jordan. Future research is required to determine if these results can be extended to Jordanian adolescent females. Implications A commitment by students via a "class smoke-free" pledge can be an added incentive to motivate adolescents in Arabic-speaking countries to abstain from smoking. Social influence approaches in schools can be useful in countering the aggressive tobacco marketing campaigns targeting Jordanian and other Arabic-speaking youth. The combination of "class smoke-free" pledges and an evidence-based peer-led asthma and smoking education can be implemented in schools to influence adolescents with asthma to abstain from smoking.

Abstract
Prevention of substance use disorders Abstract. Introduction: Adolescence is a vulnerable period for the development of Substance Use Disorders and preventive intervention is a public health priority. In this article, we summarize the available evidence for behavioral preventive action for Substance Use Disorders and related dysregulated behaviors during adolescence in various settings. Results: Current meta-analytic evidence is available mainly for the school and family settings and increasingly also for internet-based prevention. The literature is dominated by US-studies that focus on universal school-based approaches for legal substances in middle adolescence. Only few German studies are published. Taken together the results indicate that developmentally sensitive substance use prevention is effective across different settings with consistent small-to-middle sized effects. Differential effectiveness analyses for schoolbased prevention suggest that younger adolescents benefit most from universal prevention, while for older adolescents targeted approaches are more effective. Conclusions: Across the relevant settings, effective preventive measures are available. However, the results could be improved. There is a need for translational research on effective and more individualized approaches to prevention and differential effects of intervention modules. Moreover, there is a need for research on the implementation of evidence-based programs and especially in Germany, coordinated approaches on community levels are lacking.

Abstract
BACKGROUND In a survey taken in Germany in 2015, 14.1% of the 12- to 17-year-olds surveyed had practiced binge drinking at least once in the preceding 30 days. The school program "Klar bleiben" ("Keep a Clear Head") was designed for and implemented among 10th graders. The participants committed themselves to abstain from binge drinking for 9 weeks. We studied whether this intervention influenced the frequency and intensity of binge drinking. METHODS This cluster-randomized controlled trial was carried out in 196 classes of 61 schools, with a total of 4163 participants with a mean age of 15.6 years (standard deviation 0.73 years). Data were collected by questionnaire in late 2015, before the intervention and again six months later. The primary endpoints were the frequency of consumption of at least 4 or 5 alcoholic drinks (for girls and boys, respectively) and the typical quantity consumed. This trial was registered in the German Clinical Trials Registry (Deutsches Register Klinischer Studien, DRKS) with the DRKS ID number DRKS00009424. RESULTS At the beginning of the trial, there was no difference between the intervention group and the control group with respect to the primary endpoints. After the intervention, differences were found among participants who had consumed alcohol before the trial (73.2% of the overall sample): binge drinking at least once in the preceding month was reported by 49.4% of the control group and by 44.2% in the intervention group (p = 0.028). The mean number of alcoholic drinks consumed in each drinking episode was 5.20 in the control group and 5.01 in the intervention group (p = 0.047). CONCLUSION The intervention was effective only in the large subgroup of adolescents who had previously consumed alcohol: they drank alcohol less often and in smaller amounts than their counterparts in the control group.

Abstract
The competition for smoke-free classes, the "Be Smart - Don't Start" program has been implemented in Germany since 1997. Using contract management techniques, school classes participating in the competition commit themselves to abstain from smoking for six months. Classes report on a regular basis whether they have stayed smoke-free or not. After the end of the competition period, successful classes participate in a prize draw. The competition aimes to influence social norms.Over the past 20 years, the competition has become a major school-based intervention to prevent smoking in Germany. Several studies addressed process and outcome evaluation, cost-benefit efficacy and iatrogenic effects. Following the evidence so far, the intervention is feasible for implementation in school routines, evokes positive feedback in teachers and students, and reveals a positive cost-benefit ratio. Findings from controlled studies imply that negative side-effects are unlikely to occur and that participation in the competition affects the progression of smoking positively at least in the short term.

Abstract
School-based interventions for increasing physical activity among children are widespread, however there is still a lack of knowledge about how school context factors are linked to implementation quality and effectiveness of programmes. The aim of this paper is to examine teacher-perceived effectiveness of a Danish national classroom-based health programme 'Active Around Denmark' and in particular, to investigate whether perceptions vary as a function of school social context factors. After completion of the programme all teachers (N = 5.892) received an electronic questionnaire. 2.097 completed the questionnaire (response rate 36%) and 1.781 datasets could be used for analysis. The teachers were asked about their perceptions of changes in children's attitudes towards and levels of physical activity after the competition. Our results indicated that certain contextual factors, such as schools' prioritization of health promotion, teachers' support by their school principal in implementation as well as teacher's satisfaction with the school' physical environment made a significant difference in teacher-perceived effectiveness. To conclude, teacher-perceived effectiveness of the health programme does vary as a function of school social context factors.

Abstract
Physical inactivity, an unhealthy diet, smoking, and alcohol consumption are key determinants of morbidity and mortality. These health behaviours often begin at a young age and track into adulthood, emphasising a need for interventions in children and young people. Previous research has demonstrated the potential effectiveness of behavioural incentive (BI) interventions in adults. However, little is known about their effectiveness in children and adolescents. Eight bibliographic databases were searched. Eligibility criteria included controlled trials using behavioural incentives (rewards provided contingent on successful performance of the target behaviour) as an intervention component for health behaviour change in children and adolescents. Intervention effects (standardised mean differences or odds ratios) were calculated and pooled by health behaviour, using a random effects model. Twenty-two studies were included (of n = 8392 identified), 19 of which were eligible for meta-analysis: physical activity (n = 8); healthier eating (n = 3); and smoking (n = 8). There was strong evidence that behavioural incentives may encourage healthier eating behaviours, some evidence that behavioural incentives were effective for encouraging physical activity behaviour, and limited evidence to support the use of behavioural incentives for smoking cessation and prevention in adolescents. Findings suggest that behavioural incentives may encourage uptake and initiation of healthy eating and physical activity in young people. However, this is a limited evidence base and a wide range of incentive designs have yet to be explored. Future research should further investigate the acceptability of these intervention approaches for young people.

Abstract
Zusammenfassung. Zielsetzung: Zur Beeinflussung der sozialen Norm verpflichten sich beim schulischen Nichtraucherwettbewerb „Be Smart – Don’t Start“ Schulklassen für 6 Monate nicht zu rauchen. Ziel der Studie war, die langfristige Wirksamkeit des Wettbewerbs zu untersuchen. Methodik: 2006 nahmen 3.490 Schüler der 7. Klassenstufe aus 84 Schulen des Landes Sachsen-Anhalt an einer cluster-randomisierten Begleitstudie teil. Diese Stichprobe wurde 2015, neun Jahre nach der Eingangserhebung, erneut kontaktiert und zu ihrem Rauchverhalten befragt. Endpunkte der Untersuchung waren Nierauchen, tägliches Rauchen, Rauchbeginn und Rauchstopp. Ergebnisse: 58 Schulen (69,0 %) erklärten sich zur Teilnahme an der Folgeuntersuchung bereit. Daraus resultierten 688 (19,7 %) Fragebogen von ehemaligen Schülern, die der Eingangserhebung zugeordnet werden konnten (mittleres Alter in 2015: 21,2 Jahre). Personen mit niedrigerem Risiko für das Rauchen wurden bei der Nachuntersuchung häufiger erreicht. Es zeigte sich darüber hinaus, dass in der Kontrollgruppe überzufällig häufig Gymnasiasten erreicht wurden. Nahezu alle Analysen wiesen auf numerisch günstigere Werte in der Interventions- im Vergleich zur Kontrollgruppe hin; dieser Unterschied wurde für den Rauchstopp auch statistisch bedeutsam. Schlussfolgerungen: Aufgrund der geringen Stichprobengröße sowie der differentiellen Attrition sind Schlussfolgerungen zu langfristigen Effekten einer Wettbewerbsteilnahme nur mit großer Vorsicht zu ziehen.

Abstract
Several school-based prevention programmes have been developed and used to prevent, delay, or reduce substance misuse, and related problems among community samples of adolescents. However, findings indicate that many of these interventions are associated with null, small, or mixed effects in reducing adolescent substance misuse, in particular for those mostly at risk of transitioning to substance use disorders. These findings highlight the need to shift the focus of substance use prevention efforts toward intervention strategies which directly target high-risk adolescents. The Preventure programme was designed to target four personality risk factors for substance misuse: hopelessness, anxiety sensitivity, impulsivity, and sensation seeking. This article reviews findings from the previous trials of personality-targeted interventions (i.e., Preventure programme) with adolescents and discuss the promises and benefits of these interventions for targeting community samples of high-risk adolescents at school level for reducing substance misuse and related mental health problems. Findings indicated that this programme has been successful in reducing the rates of alcohol and illicit drug use and substance-related harms by ~50% in high-risk adolescents with the effects last for up to 3 years. These interventions were also associated with a 25% reduction in likelihood of transitioning to mental health problems, such as anxiety, depression, suicidal ideation, and conduct problems. The programme is particularly beneficial for youth with more significant risk profiles, such as youth reporting clinically significant levels of externalizing problems, and victimized adolescents. A key strength of the Preventure programme is that it is embedded in the community and provides substance use intervention at school level to the general samples of high-risk adolescents who might not otherwise have access to those programmes.

Abstract
Active school travel (AST) is an important source of physical activity for children and a conceptual understanding of AST is necessary to inform promotion efforts. The aim of this article is to provide a conceptual analysis of AST. All currently identified AST formulations include intra-individual variables which are often recommended as intervention targets. However, existing literature lacks clarity on precisely how these intra-individual variables might shape specific AST interventions. Moreover, evaluative studies of AST interventions typically fail to specify an underpinning theory or model. To address this limitation, the Behavioural Ecological Model (BEM), not previously addressed in AST, is presented to guide this area of research. Based on specific examples, we draw attention to the role of potential antecedents and potential reinforcers of AST, as well as potential reinforcers of motorised travel. Antecedents and reinforcers may help to explain choices of school travel mode, and to inform and increase intervention options to promote AST. Consistent with the BEM, the provision of more immediate consequences, such as fun and material prizes, is an evidence-based strategy for increasing AST which is likely to be low-cost and easier to deliver than alternative interventions. This approach to the study of AST is expected to contribute to similar analyses in this and other areas of behaviour change research, and to a more useful discussion and treatment of theoretical and conceptual behavioural models.

Abstract
BACKGROUND Adult smoking usually has its roots in adolescence. If individuals do not take up smoking during this period it is unlikely that they ever will. Further, once smoking becomes established, cessation is challenging; the probability of subsequently quitting is inversely proportional to the age of initiation. One novel approach to reducing the prevalence of youth smoking is the use of incentives. OBJECTIVES To assess the effect of incentives on preventing children and adolescents (aged 5 to 18 years) from starting to smoke. It was also our intention to assess, where possible, the dose-response of incentives, the costs of incentive programmes, whether incentives are more or less effective in combination with other interventions to prevent smoking initiation, and any unintended consequences arising from the use of incentives. SEARCH METHODS For the original review (published 2012) we searched the Cochrane Tobacco Addiction Group Specialized Register, with additional searches of MEDLINE, Embase, CINAHL, CSA databases and PsycINFO for terms relating to incentives, in combination with terms for smoking and tobacco use, and children and adolescents. The most recent searches were of the Cochrane Tobacco Addiction Group Specialized Register, and were carried out in December 2016. SELECTION CRITERIA We considered randomized controlled trials (RCTs) allocating children and adolescents (aged 5 to 18 years) as individuals, groups or communities to intervention or control conditions, where the intervention included an incentive aimed at preventing smoking uptake. We also considered controlled trials (CTs) with baseline measures and post-intervention outcomes. DATA COLLECTION AND ANALYSIS Two review authors extracted and independently assessed the data. The primary outcome was the smoking status of children or adolescents at follow-up who reported no smoking at baseline. We required a minimum follow-up of six months from baseline and assessed each included study for risks of bias. We used the most rigorous definition of abstinence in each trial; we did not require biochemical validation of self-reported tobacco use for study inclusion. Where possible we combined eligible studies to calculate pooled estimates at the longest follow-up, using the Mantel-Haenszel fixed-effect method, grouping studies by study design. MAIN RESULTS We identified three eligible RCTs and five CTs, including participants aged 11 to 14 years, who were non-smokers at baseline. Of the eight trials identified, six had analyzable data relevant for this review, which contributed to meta-analyses (7275 participants in total: 4003 intervention; 3272 control; 2484 participants after adjusting for clustering). All except one of the studies tested the 'Smokefree Class Competition' (SFC), which has been widely implemented throughout Europe. In this competition, classes with youth generally between the ages of 11 and 14 years commit to being smoke-free for a six-month period, and report their smoking status regularly. If 90% or more of the class are non-smokers at the end of the six months, the class goes into a competition to win prizes. The one study that was not a trial of the SFC was a controlled trial in which schools in two communities were assigned to the intervention, with schools in a third community acting as controls. Students in the intervention community with lower smoking rates at the end of the project (one school year) received rewards.Most studies resulted in statistically non-significant results. Only one study of the SFC reported a significant effect of the competition on the prevention of smoking at the longest follow-up. However, this study was at risk of multiple biases, and when we calculated the adjusted risk ratio (RR) we no longer detected a statistically significant difference. The pooled RR for the more robust RCTs (3 studies, n = 3056 participants/1107 adjusted for clustering) suggests that there is no statistically significant effect of incentives, in the form of the SFC, to prevent smoking initiation among children and adolescents in the long term (RR 1.00, 95% confidence interval (CI) 0.84 to 1.19). Pooled results from the non-randomized trials also did not detect a significant effect of the SFC, and we were unable to extract data on our outcome of interest from the one trial that did not study the SFC. There is little robust evidence to suggest that unintended consequences (such as making false claims about their smoking status and bullying of smoking students) are consistently associated with such interventions, although this has not been the focus of much research. There was insufficient information to assess the dose-response relationship or to report costs of incentives for preventing smoking uptake.We judged the included RCTs to be at unclear risk of bias, and the non-RCTs to be at high risk of bias. Using GRADE, we rated the overall quality of the evidence for our primary outcome as 'low' (for RCTs) and 'very low' (for non-RCTs), because of imprecision (all studies had wide confidence intervals), and for the risks of bias identified. We further downgraded the non-RCT evidence, due to issues with the non-RCT study design, likely to introduce further bias. AUTHORS' CONCLUSIONS The very limited evidence currently available suggests that incentive programmes do not prevent smoking initiation among youth. However, there are relatively few published studies and these are of variable quality. In addition, trials included in the meta-analyses were all studies of the SFC, which distributed small to moderately-sized prizes to whole classes, usually through a lottery system. It is therefore possible that other incentive programmes could be more successful at preventing smoking uptake in young people.Future studies might investigate the efficacy of a wider range of incentives, including those given to individual participants to prevent smoking uptake, whilst considering both the effect of incentives on smoking initiation and the progression to smoking. It would be useful if incentives were evaluated in varying populations from different socioeconomic and ethnic backgrounds, and if intervention components were described in detail.

Abstract
BACKGROUND The aim of the study was to address the lack of evaluations of school-based substance use prevention programs and to conduct a quasi-experimental evaluation of the alcohol use part of the Triad intervention. METHODS Eleven Swedish intervention schools (285 pupils) and three control schools (159 pupils) participated in the evaluation. Baseline measurements were conducted in 2011 before the alcohol part in the prevention program was implemented in the intervention schools (school year 6, ages 12-13). We estimated an Intention-To-Treat (ITT) Difference-in-Difference (DD) model to analyze the effectiveness of the intervention on subsequent alcohol use measured in grades 7, 8 and 9. RESULTS The main results show no effect on the likelihood of drinking alcohol or drinking to intoxication. CONCLUSIONS The lack of positive effects highlights the need for policy-makers and public health officials need to carefully consider and evaluate prevention programs in order to ensure that they are worthwhile from school, health, and societal perspectives.

Abstract
Many unhealthy behaviors often begin during adolescence and represent major public health challenges. Substance abuse has a major impact on individuals, families, and communities, as its effects are cumulative, contributing to costly social, physical, and mental health problems. We conducted an overview of systematic reviews to evaluate the effectiveness of interventions to prevent substance abuse among adolescents. We report findings from a total of 46 systematic reviews focusing on interventions for smoking/tobacco use, alcohol use, drug use, and combined substance abuse. Our overview findings suggest that among smoking/tobacco interventions, school-based prevention programs and family-based intensive interventions typically addressing family functioning are effective in reducing smoking. Mass media campaigns are also effective given that these were of reasonable intensity over extensive periods of time. Among interventions for alcohol use, school-based alcohol prevention interventions have been associated with reduced frequency of drinking, while family-based interventions have a small but persistent effect on alcohol misuse among adolescents. For drug abuse, school-based interventions based on a combination of social competence and social influence approaches have shown protective effects against drugs and cannabis use. Among the interventions targeting combined substance abuse, school-based primary prevention programs are effective. Evidence from Internet-based interventions, policy initiatives, and incentives appears to be mixed and needs further research. Future research should focus on evaluating the effectiveness of specific interventions components with standardized intervention and outcome measures. Various delivery platforms, including digital platforms and policy initiative, have the potential to improve substance abuse outcomes among adolescents; however, these require further research.

Abstract
OBJECTIVE To examine the efficacy of a smoking prevention program which aimed to address smoking related cognitions and smoking behavior among Saudi adolescents age 13 to 15. METHOD A randomized controlled trial was used. Respondents in the experimental group (N=698) received five in-school sessions, while those in the control group (N=683) received no smoking prevention information (usual curriculum). Post-intervention data was collected six months after baseline. Logistic regression analysis was applied to assess effects on smoking initiation, and linear regression analysis was applied to assess changes in beliefs and analysis of covariance (ANCOVA) was used to assess intervention effects. All analyses were adjusted for the nested structure of students within schools. RESULTS At post-intervention respondents from the experimental group reported in comparison with those from the control group a significantly more negative attitude towards smoking, stronger social norms against smoking, higher self-efficacy towards non-smoking, more action planning to remain a non-smoker, and lower intentions to smoke in the future. Smoking initiation was 3.2% in the experimental group and 8.8% in the control group (p<0.01). CONCLUSION The prevention program reinforced non-smoking cognitions and non-smoking behavior. Therefore it is recommended to implement the program at a national level in Saudi-Arabia. Future studies are recommended to assess long term program effects and the conditions favoring national implementation of the program.

Abstract
BACKGROUND In 2013, around 40 % of the schools in Sweden had structured programs to prevent tobacco and alcohol debut in compulsory school. There has unfortunately been a lack of scientific evidence to support most of the prevention methods focusing on primary prevention in schools in Sweden. The aim and purpose of the present study is to evaluate the effectiveness of the Non-Governmental Organization SMART contract-signing strategy in reducing the growth of youth substance use and other problem behaviors amongst Swedish adolescents. METHODS Students from five schools in a medium-sized Swedish municipality were surveyed in three waves from 7(th) to 9(th) grade of compulsory school. We used General Linear Model (GLM) repeated-measures ANOVA to test if the outcome measures smoking, use of snus and alcohol, drunkenness, delinquency, and bullying significantly changed different amounts over time in groups that had participated in the SMART program for long time, a short time, sporadically- or not at all. Groups were compared on demographic background variables, and outcome measures were assessed on all measurement occasions by a one-way ANOVA. The magnitude of group differences at the end of the study was estimated according to Cohen's d. RESULTS Number of years with a contract has an effect on the levels of self-reported youth problems in 9(th) grade. We found small to medium-sized differences in measured outcomes between students who participated in the program for the longest period of time, 5 years, and who participated for the shortest time, 0-2 years. CONCLUSION Findings suggests that the SMART program has preventive effects on adolescent substance use.

Abstract
INTRODUCTION There is a noticeable increase in hazardous alcohol use during adolescence, which is significantly associated with adverse consequences. In Germany, up to 30% of adolescents report regular heavy episodic drinking. However, only a few German prevention programmes target adolescents of legal drinking age (16 years and above); thus, this trial aims to develop, implement and evaluate 'Klar bleiben' ('Stay clearheaded'), a school-based prevention programme for grade 10 students. METHODS AND ANALYSIS 'Klar bleiben' consists of a class commitment to drink responsibly and refrain from hazardous consumption patterns for 9 weeks. The commitment is accompanied by educational lessons on alcohol-related cognitions and consequences. It will be evaluated in a sample of approximately 3000 students (150 classes) from two German federal states (Schleswig-Holstein and Lower Saxony) via a two-armed cluster randomised controlled trial with baseline and postassessment 6 months apart. The intervention group (75 classes) will participate in 'Klar bleiben', whereas the control group (75 classes) will receive education as usual. 'Klar bleiben' addresses classes, individuals, teachers and parents. It is based on a social norms approach and aims to reduce hazardous drinking and drinking-related consequences in adolescents. Secondary outcomes include general drinking behaviour, use of other substances, alcohol-related cognitions and social factors. Covariates include sociodemographic characteristics, environmental and individual (vulnerability) factors. ETHICS AND DISSEMINATION 'Klar bleiben' provides a multicomponent school-based programme that bridges a gap in alcohol prevention. Similar class-level and social norms-based prevention programmes have already been proven to be successful for other substances among adolescents. Thus, dissemination to other federal states as well as longer term follow-up testing of the robustness of effects is to be anticipated. The study was approved by the Ethics Committee of the German Psychological Society (RH_0620152), and study findings will be disseminated through peer-reviewed publications and conference contributions.

Abstract
BACKGROUND Government interventions are critical to addressing the global tobacco epidemic, a major public health problem that continues to deepen. We systematically synthesize research evidence on the effectiveness of government tobacco control policies promoted by the Framework Convention on Tobacco Control (FCTC), supporting the implementation of this international treaty on the tenth anniversary of it entering into force. METHODS An overview of systematic reviews was prepared through systematic searches of five electronic databases, published up to March 2014. Additional reviews were retrieved from monthly updates until August 2014, consultations with tobacco control experts and a targeted search for reviews on mass media interventions. Reviews were assessed according to predefined inclusion criteria, and ratings of methodological quality were either extracted from source databases or independently scored. RESULTS Of 612 reviews retrieved, 45 reviews met the inclusion criteria and 14 more were identified from monthly updates, expert consultations and a targeted search, resulting in 59 included reviews summarizing over 1150 primary studies. The 38 strong and moderate quality reviews published since 2000 were prioritized in the qualitative synthesis. Protecting people from tobacco smoke was the most strongly supported government intervention, with smoke-free policies associated with decreased smoking behaviour, secondhand smoke exposure and adverse health outcomes. Raising taxes on tobacco products also consistently demonstrated reductions in smoking behaviour. Tobacco product packaging interventions and anti-tobacco mass media campaigns may decrease smoking behaviour, with the latter likely an important part of larger multicomponent programs. Financial interventions for smoking cessation are most effective when targeted at smokers to reduce the cost of cessation products, but incentivizing quitting may be effective as well. Although the findings for bans on tobacco advertising were inconclusive, other evidence suggests they remain an important intervention. CONCLUSION When designing and implementing tobacco control programs, governments should prioritize smoking bans and price increases of tobacco products followed by other interventions. Additional studies are needed on the various factors that can influence a policy's effectiveness and feasibility such as cost, local context, political barriers and implementation strategies.

Abstract
BACKGROUND Suicidal behaviours in adolescents are a major public health problem and evidence-based prevention programmes are greatly needed. We aimed to investigate the efficacy of school-based preventive interventions of suicidal behaviours. METHODS The Saving and Empowering Young Lives in Europe (SEYLE) study is a multicentre, cluster-randomised controlled trial. The SEYLE sample consisted of 11,110 adolescent pupils, median age 15 years (IQR 14-15), recruited from 168 schools in ten European Union countries. We randomly assigned the schools to one of three interventions or a control group. The interventions were: (1) Question, Persuade, and Refer (QPR), a gatekeeper training module targeting teachers and other school personnel, (2) the Youth Aware of Mental Health Programme (YAM) targeting pupils, and (3) screening by professionals (ProfScreen) with referral of at-risk pupils. Each school was randomly assigned by random number generator to participate in one intervention (or control) group only and was unaware of the interventions undertaken in the other three trial groups. The primary outcome measure was the number of suicide attempt(s) made by 3 month and 12 month follow-up. Analysis included all pupils with data available at each timepoint, excluding those who had ever attempted suicide or who had shown severe suicidal ideation during the 2 weeks before baseline. This study is registered with the German Clinical Trials Registry, number DRKS00000214. FINDINGS Between Nov 1, 2009, and Dec 14, 2010, 168 schools (11,110 pupils) were randomly assigned to interventions (40 schools [2692 pupils] to QPR, 45 [2721] YAM, 43 [2764] ProfScreen, and 40 [2933] control). No significant differences between intervention groups and the control group were recorded at the 3 month follow-up. At the 12 month follow-up, YAM was associated with a significant reduction of incident suicide attempts (odds ratios [OR] 0·45, 95% CI 0·24-0·85; p=0·014) and severe suicidal ideation (0·50, 0·27-0·92; p=0·025), compared with the control group. 14 pupils (0·70%) reported incident suicide attempts at the 12 month follow-up in the YAM versus 34 (1·51%) in the control group, and 15 pupils (0·75%) reported incident severe suicidal ideation in the YAM group versus 31 (1·37%) in the control group. No participants completed suicide during the study period. INTERPRETATION YAM was effective in reducing the number of suicide attempts and severe suicidal ideation in school-based adolescents. These findings underline the benefit of this universal suicide preventive intervention in schools. FUNDING Coordination Theme 1 (Health) of the European Union Seventh Framework Programme.

Abstract
OBJECTIVE The aim of this study is to test whether participation in the Smoke-Free Class Competition (SFC), a classroom-based smoking prevention program, reduced smoking and increased smoking-related knowledge among those with and without smoking peers compared to control groups. METHOD Including smoking peers as a moderator in multilevel models, a quasi-experimental design with a post-test at seven months was used to analyze data from 1035 students in Switzerland (2011; mean age 13.3, 53.2% female). RESULTS Completing the SFC decreased smoking prevalence (OR=0.7; CI=0.5-1.0; ns) and increased smoking-related knowledge (b=1.0; p<.01) compared to control classes. However, the former effect was only significant among those without smoking peers (OR=0.3; CI=0.2-0.5; p<.001). With smoking peers, smoking prevalence was even higher at post-test (OR=3.7; CI=1.7-8.2; p<.01) in the classes that completed SFC compared to controls. No effect was found in classes that started SFC but had to pull out. CONCLUSIONS The results indicate that SFC should be applied early in adolescence, when individuals are less likely to have classmates who smoke and are therefore less likely to have to pull out of the program. This is particularly important because SFC was only effective among those who completed the program and did not have smoking peers.

Abstract
Behavioral incentives have been used to encourage smoking cessation in older adolescents, but the acceptability of incentives to promote a smoke-free lifestyle in younger adolescents is unknown. To inform the development of novel, effective, school-based interventions for youth, we assessed middle school students' interest in participating in an incentive-based tobacco abstinence program. We surveyed 988 students (grades 6–8) attending three Connecticut middle schools to determine whether interest in program participation varied as a function of (1) intrapersonal factors (i.e., demographic characteristics (sex, age, race), smoking history, and trait impulsivity) and/or (2) aspects of program design (i.e., prize type, value, and reward frequency). Primary analyses were conducted using multiple regression. A majority of students (61.8%) reported interest in program participation. Interest did not vary by gender, smoking risk status, or offering cash prizes. However, younger students, non-Caucasian students, behaviorally impulsive students, and students with higher levels of self-regulation were more likely to report interest. Inexpensive awards (e.g., video games) offered monthly motivated program interest. In sum, middle school students reported high levels of interest in an incentive-based program to encourage a tobacco-free lifestyle. These formative data can inform the design of effective, incentive-based smoking cessation and prevention programs in middle schools.

Abstract
Using stochastic actor-based models for longitudinal network analysis, this study examines the role of friends' smoking attitudes and behavior for Dutch adolescents' smoking behavior in four secondary schools (N = 875). The data were collected in two waves in two small suburban towns under second graders in 2008 to 2009 by means of a standardized questionnaire. Stochastic actor-based models for longitudinal network analysis can control for friendship selection while examining the effect of friends' attitudes and smoking behavior on the smoking behavior of a student. The findings suggest that friends tend to select each other on similar smoking behavior. Influence of friends' smoking behavior seems to play no role. In one school, an effect of friends' attitudes towards smoking on the smoking behavior is found. The implications for future research are to consider attitudes when examining the influence of friendship network on smoking behavior. The main limitation of this study lies in the limited sample, which makes generalizations to the general population difficult.

Abstract
This review presents findings from an overview of meta-analyses of the effects of prevention and promotion programs to prevent mental health, substance use, and conduct problems. The review of 48 meta-analyses found small but significant changes that reduce depression, anxiety, antisocial behavior, and substance use. Furthermore, the results were sustained over time. Meta-analyses often found that the effects were heterogeneous. A conceptual model is proposed to guide the study of moderators of program effects in future meta-analyses, and methodological issues in synthesizing findings across preventive interventions are discussed.

Abstract
OBJECTIVE This study aims to evaluate the short-term effects of a home-based smoking prevention program called 'Smoke-free Kids' on antismoking socialization and smoking-related cognitions and the moderating role of parental smoking. PARTICIPANTS AND METHODS A cluster randomized controlled trial was carried out using one intervention condition compared with a control condition. A total of 1,398 never-smoking children (mean age 10.11 years, SD 0.78) participated. Intention-to-treat and completers-only analyses were performed. Participants in the intervention condition (n=728) received 5 activity modules by mail at 4-week intervals. Modules included communication sheets for their mothers. Participants in the control condition (n=750) received a fact-based intervention only. The main outcomes were the frequency and quality of communication, nonsmoking agreement, house rules, availability of cigarettes, perceived maternal influence, anticipated maternal reactions, attitude, self-efficacy and social norms. RESULTS Significant effects of the program were found for frequency of communication (B=0.11, p<0.001), nonsmoking agreement (B=0.07, p<0.01), perceived maternal influences (B=0.09, p<0.05), self-efficacy (B=-0.09, p<0.05) and social norms of friends (B=-0.08, p=0.05) and best friends (B=-0.11, p<0.05). Parental smoking had no moderating effect. CONCLUSIONS The Smoke-free Kids program shows promising short-term effects on antismoking socialization and cognitions. Long-term follow-up on the effects of smoking behavior are needed.

Abstract
The aim of this study is to examine the role of Dutch second grade (age 13–14) high school peer networks in mediating socioeconomic background and school type effects on smoking behavior. This study is based on a longitudinal design with two measurement waves at five different high schools, of the complete networks of second grader friendships, as well as their smoking behavior, school type, and parents’ educational level. The analysis is done by simulation investigation for empirical network analysis (SIENA) modeling that can control for friendship selection on the basis of smoking similarity when assessing friends’ influence on smoking. The findings show that, when controlling for friendship selection, the influence of friends still plays a significant role in adolescent smoking behavior, and suggests that socioeconomic background and school type effects on smoking are mediated by the friendship networks at school.
