Effectiveness of a self-help guide during a temporary alcohol abstinence challenge: a randomized controlled trial.

BACKGROUND: The popularity of temporary abstinence challenges (TACs) concerning alcohol consumption is increasing. Support is found to be essential for participants to help them get through a challenge. This study aimed to evaluate the additional effect of a self-help guide, based on health behaviour theories and behaviour change techniques, on (i) successful completion of a TAC and (ii) changes in drinking refusal self-efficacy (DRSE), behavioural automaticity, craving, and alcohol consumption. METHODS: A randomized controlled trial was performed (OSF registries: OSF.IO/B95VU). NoThanks participants received a questionnaire before the TAC (T0) and 8 months after the TAC (T1). Out of a subgroup of 1308 respondents who were interested in additional support, 652 were randomly assigned to receive the guide (experimental group), and 656 did not receive any additional support (control group). Logistic regressions and (generalized) linear mixed model analyses were used. RESULTS: After 8 months, all participants showed a significant decrease in behavioural automaticity, craving, and alcohol consumption, irrespective of group assignment. No significant changes were observed in the DRSE. This degree of change over time in behavioural automaticity, craving, and alcohol consumption did not differ between the experimental and control group. Sensitivity analyses with participants in the experimental group, who differed in exposure to the guide, did not show differences either. CONCLUSION: The self-help guide, and how it was designed, added no value to the TAC. Future research should focus on more bottom-up, customized support and explore what (different subgroups of) participants think they need as extra support during a TAC.

Professionals' perspectives on interventions to reduce problematic alcohol use in older adults: a realist evaluation of working elements.

OBJECTIVES: This study set out to understand how (which elements), in what context and why (which mechanisms) interventions are successful in reducing (problematic) alcohol use among older adults, from the perspective of professionals providing these interventions. DESIGN: Guided by a realist evaluation approach, an existing initial programme theory (IPT) on working elements in alcohol interventions was evaluated by conducting semistructured interviews with professionals. SETTING AND PARTICIPANTS: These professionals (N=20) provide interventions across several contexts: with or without practitioner involvement; in-person or not and in an individual or group setting. Data were coded and links between contexts, elements, mechanisms and outcomes were sought for to confirm, refute or refine the IPT. RESULTS: From the perspective of professionals, there are several general working elements in interventions for older adults: (1) pointing out risks and consequences of drinking behaviour; (2) paying attention to abstinence; (3) promoting contact with peers; (4) providing personalised content and (5) providing support. We also found context-specific working elements: (1) providing personalised conversations and motivational interviewing with practitioners; (2) ensuring safety, trust and a sense of connection and a location nearby home or a location that people are familiar with in person and (3) sharing experiences and tips in group interventions. Furthermore, the mechanisms awareness and accessible and low threshold participation were important contributors to positive intervention outcomes. CONCLUSION: In addition to the IPT, our findings emphasise the need for social contact and support, personalised content, and strong relationships (both between client and practitioner, and client and peers) in interventions for older adults.

The contribution of Dutch municipalities to stimulate smoke-free outdoor sports clubs: a qualitative study.

Local governments may play a key role in making outdoor sports clubs smoke free. This study aims to assess the activities, motives, challenges and strategies of Dutch municipalities regarding stimulating outdoor sports clubs to become smoke free. Semi-structured interviews were conducted with 19 policy officers of different municipalities in the Netherlands. The included municipalities varied in terms of region, population size and degree of urbanization. Data were analyzed using content analysis. Municipalities stimulated sports clubs to become smoke free by providing information and support and, to a lesser extent, by using financial incentives. Motives of municipalities varied from facilitating a healthy living environment for youth, responding to denormalization of smoking and aligning with goals formulated in national prevention policy. Policy officers faced several challenges, including limited capacity and funds, a reluctance to interfere with sports clubs and little support within the municipal organization. These challenges were addressed by employing various strategies such as embedding smoke-free sports in a broader preventive policy, setting a good example by creating outdoor smoke-free areas around municipal buildings, and collaborating with stakeholders in the municipality to join forces in realizing smoke-free sports clubs. Municipalities demonstrated evident motivation to contribute to a smoke-free sports environment. Currently, most municipalities fulfil an informative and supportive role, while some municipalities still explore their role and position in relation to supporting sports clubs to become smoke free. Other municipalities have established, according to them, effective strategies.

Smoking cessation support in social and community service organizations: potential activities, barriers and facilitators.

INTRODUCTION: Social and Community Service Organizations (SCSOs) are a potential setting to reach and support people with a low socioeconomic position who smoke, yet smoking cessation is not widely supported by SCSO professionals. This study aims to identify SCSO professionals' 1) potential activities to support smoking cessation and 2) barriers and facilitators in undertaking these activities. METHODS: Between July and November 2022, semi-structured interviews were conducted with 21 professionals recruited through SCSOs in Amsterdam North, including participation workers, welfare workers, parent and child counselors, budget coach, debt counselor, welfare work, community sports and community center coordinators. Data were analyzed using a thematic approach. RESULTS: Eight activities were identified that could support the client either directly (i.e., recognizing smoking clients, discussing smoking and smoking cessation, referring clients, providing smoking cessation counseling, offering help around services) or indirectly (i.e., collaboration with relevant network partners, implementing smoke-free environments, enhancing professional skills). Various barriers and facilitators were identified related to the 1) client and their environment (i.e., clients' readiness and social environment), 2) interaction between professional and client (i.e., topic sensitivity), 3) professional (i.e., professionals is non-smoker, knowledge and self-efficacy), 4) professionals' work environment (i.e., necessity, responsibility, priority and time), and 5) smoking cessation services (i.e., availability of appropriate services and referral process). CONCLUSIONS: There is potential for SCSO professionals to support smoking cessation, but several barriers hinder their efforts. To address these barriers, it is essential to take into account the factors that SCSO professionals believe facilitate the provision of smoking cessation support. IMPLICATIONS: This study provides insight into how the potential of SCSOs in Amsterdam North to support smoking cessation efforts among people with a low socioeconomic position can be harnessed. Barriers were found at multiple levels (client, professional, client-professional interaction, and organizational) and these findings imply that stakeholders across these levels will need to prioritize smoking cessation to facilitate and stimulate SCSO professionals in supporting smoking cessation. A concrete action would be to offer SCSO professionals additional training conversational skills to discuss smoking. As a prerequisite, easily accessible and suitable smoking cessation services should be available in the neighborhood.

Outdoor smoke-free policies at sports clubs across Europe: Current status, recent evidence, and future challenges.

OBJECTIVE: This commentary emphasizes the importance of implementing outdoor smoke-free policies at sports clubs, particularly highlighting their limited adoption across Europe. The primary aim was to assess the progress made in the Netherlands, explore the strategies employed, and outline future challenges. METHODS: Our methodology involved an examination of national regulations and the voluntary adoption of smoke-free policies at sports clubs throughout Europe. We also assessed the adoption and implementation of these policies using recent evidence, leading to the identification of impending challenges in their implementation across Europe. RESULTS: While only a few European countries currently have national legislation prohibiting outdoor smoking at sports clubs, voluntary initiatives promoting such policies have emerged in various nations. Experiences from the Netherlands have demonstrated the feasibility of implementing outdoor smoke-free policies at sports clubs. To expand these policies across Europe, five key challenges need to be addressed: 1) encouraging smoke-free policies at sports clubs that are less inclined to adopt them, 2) ensuring consistent compliance and enforcement of outdoor smoke-free policies, 3) preventing smoking just outside the sports club, 4) garnering support from various stakeholders to ensure widespread adoption of smoke-free sports clubs, and 5) establishing monitoring and evaluation mechanisms for policy implementation. CONCLUSION: The Dutch experiences serve as a testimony to the feasibility of outdoor smoke-free policies at sports clubs. By addressing the remaining challenges, we can create healthier sports environments for children and take substantial steps towards realizing a smoke-free Europe.

Interdisciplinary collaboration in the treatment of alcohol use disorders in a general hospital department: a mixed-method study.

BACKGROUND: Interdisciplinary collaborations (i.e., where various disciplines work coordinated and interdependently toward shared goals) are stated to yield higher team effectiveness than multidisciplinary approaches (i.e., where various disciplines work in parallel within their professional boundaries) in somatic health care settings. Nevertheless, research is lacking on interdisciplinary approaches for alcohol use disorder (AUD) treatment of hospitalized patients as these types of approaches are still uncommon. This study aims to evaluate an innovative interdisciplinary AUD treatment initiative at a general hospital department by 1) identifying which and to what extent network partners are involved and 2) to explore how network partners experienced the interdisciplinary collaboration. METHODS: A mixed-method study was conducted, using 1) measures of contact frequency and closeness in a social network analysis and 2) semi-structured interviews, which were analyzed thematically. Respondents were network partners of an interdisciplinary collaboration in a general hospital department, initially recruited by the collaborations' project leader. RESULTS: The social network analysis identified 16 network partners, including a 'core' network with five central network partners from both inside and outside the hospital. The project leader played an important central role in the network and the resident gastroenterologist seemed to have a vulnerable connection within the network. Closeness between network partners was experienced regardless of frequency of contact, although this was especially true for the 'core' group that (almost) always consisted of the same network partners that were present at biweekly meetings. Interview data showed that presence of the 'core' network partners was reported crucial for an efficient collaboration. Respondents desired knowledge about the collaborations' effectiveness, and one structured protocol with working procedures, division of responsibilities and agreements on information sharing and feedback. CONCLUSIONS: The design of this interdisciplinary collaboration has potential in improving the treatment of hospital patients with AUD and was evaluated positively by the involved network partners. Interdisciplinary collaborations may offer a critical solution to increase treatment rates of patients with AUD and should be adopted in hospitals on a larger scale. Research towards the effectiveness of interdisciplinary collaborations in the treatment of hospitalized patients with AUD is needed.

How sports clubs decide to adopt an outdoor smoke-free policy: a qualitative study applying the Garbage Can Model.

BACKGROUND: Outdoor smoke-free policies (SFPs) at sports clubs can contribute to protecting people from second-hand smoke (SHS). However, in absence of national legislation, it is uncertain whether and how sports clubs decide to adopt an SFP. The aim of this study was to explore the decision-making process at sports clubs in relation to the adoption of an outdoor SFP. METHODS: Semi-structured interviews were held with key stakeholders at 20 Dutch sports clubs (in field hockey, football, tennis, or korfball) with an outdoor SFP. Thematic analysis was applied, and themes were defined in line with the four streams of the Garbage Can Model (GCM). RESULTS: We identified four motivating factors for sports clubs to start the decision-making process: 1) SHS as a problem, 2) intolerance of smoking behavior, 3) advantages of an outdoor SFP, and 4) external pressure to become smoke-free. The decision-making process involved a variety of participants, but the board, influential club members, and smokers usually played major roles. Decisions were discussed during both formal and informal choice opportunities, but only made during formal choice opportunities. With regard to solutions, sports clubs adopted a partial or total outdoor SFP. In addition, sports clubs followed different strategies with regard to the decision-making process, which we classified along two dimensions: 1) autocratic vs. democratic and 2) fast vs. slow. CONCLUSION: A number of factors motivated sports clubs to start the decision-making process. These factors were mainly linked to a strong non-smoking norm. Decision-making involved different participants, with a key role for the board, influential club members, and smokers. Governments and other external organizations may contribute to SFP adoption at sports clubs in several ways. They may advise clubs on strategies of decision-making and how to involve smokers in this process.

Impact of a smoke-free policy on smoking prevalence on hospital grounds: A before-after study.

INTRODUCTION: Studies on the impact of smoke-free policies (SFPs) on hospitals grounds on on-site smoking are scarce. On 1 October 2019, an SFP was implemented on the grounds of the Amsterdam UMC hospital in the Netherlands, including measures for sustained enforcement. This study assessed the impact of this SFP on smoking prevalence on hospital grounds up to 18 months after implementation. METHODS: Observations were systematically conducted 7 weeks before and after the SFP was implemented, and at 5 and 18 months afterwards. A total of 32 sites were included in the study, divided over two hospital locations. On each site, the number of smokers was systematically observed and categorized into staff, patient, student, or visitor. Smoking prevalence on hospital grounds was calculated by the number of observed smokers as a proportion of all people observed. Bubble maps were created to visualize changes in the geographical distribution of smokers. RESULTS: Smoking prevalence on hospital grounds decreased significantly from 17.4% before to 3.3% after implementation of the SFP. Following implementation, the largest decrease was observed in smoking among staff (-96.7%) and patients (-92.3%). The decrease in smoking prevalence was sustained 18 months after implementation (5.0%). The number of smokers decreased on nearly all sites. CONCLUSIONS: The substantial and sustained decrease in smoking prevalence found in this study highlights the potential of SFPs on hospital grounds to protect people from exposure to (secondhand) smoking. Continued enforcement of these SFPs seems essential to ensure ongoing compliance.

Impeding and facilitating factors for the implementation of alcohol interventions in hospitals: a qualitative and exploratory study among Dutch healthcare professionals.

BACKGROUND: Non-moderated alcohol use is more prevalent among hospitalized patients compared to the general population. However, many hospitals fail to find and intervene with people with alcohol problems. We aimed to conduct an exploration of impeding and facilitating factors experienced by healthcare professionals in implementation of alcohol interventions in Dutch general hospitals. In addition, we explored the alcohol interventions used in the selected hospitals and involved stakeholders. METHODS: Through a qualitative study, semi-structured telephone interviews were conducted with twenty healthcare professionals working in or in collaboration with six different general hospitals. RESULTS: Healthcare professionals indicated impeding and facilitating factors in the areas of motivation, knowledge and skills, patient characteristics, protocol, internal and external collaboration/support, resources, role suitability and societal support. Five different categories of approaches to identify and intervene with non-moderated alcohol use and 18 involved stakeholders from both inside and outside the hospital were found. CONCLUSIONS: Implementation of alcohol interventions for patients in Dutch general hospitals still seems to be in its infancy. Respondents emphasized the importance of one clear protocol on how to tackle alcohol problems within their hospital, repeated training on alcohol-related knowledge and skills, (clinical) "champions" that support healthcare professionals and developing and maintaining collaborations with stakeholders within and outside the hospital.

Association Between Smoke-Free Legislation in Hospitality Venues and Smoking Behavior of Young People: A Systematic Review.

INTRODUCTION: While evaluations of indoor smoke-free legislation have demonstrated major public health benefits among adults, their impact on the smoking behavior of young people remains unclear. Therefore, we performed a systematic review of the association between smoke-free legislation in hospitality venues and smoking behavior of young people. AIMS AND METHODS: A systematic search was conducted in PubMed, Scopus, and Embase in June 2020. We searched for studies that assessed the association of any form of smoke-free legislation in any hospitality venue (eg, bar and restaurant) with a smoking behavior outcome (eg, initiation and current smoking) among young people (aged 10-24 years). . RESULTS: Our search yielded 572 articles of which 31 were screened based on full-text and 9 were included in the analysis. All studies were published between 2005 and 2016. The majority of studies used a quasi-experimental design. Four studies evaluated smoke-free legislation in hospitality venues specifically. Two studies reported that comprehensive, but not weaker, smoke-free legislation decreases progression to established smoking. Two other studies provided mixed results on which level of comprehensiveness of legislation would be effective, and which smoking outcomes would be affected. Five studies evaluated legislation that also included other workplaces. Out of these five studies, three studies found significant decreases in current smoking, smoking frequency, and/or smoking quantity, whereas two other studies did not. CONCLUSIONS: Most of the studies found that smoke-free legislation in hospitality venues is associated with a decrease in smoking behavior among young people. Their results indicate the need for comprehensive smoke-free legislation without exemptions. IMPLICATIONS: This is the first systematic review to provide insight into the relationship between smoke-free legislation in hospitality venues and smoking behavior of young people. Our findings show that there is a need for comprehensive smoke-free legislation without exemptions (such as designated smoking areas).

Adolescents' beliefs, attitudes and social norms with regard to smoking and sports: a qualitative study.

OBJECTIVES: The aim of this study is to explore the beliefs, attitudes and social norms of Dutch adolescents with regard to smoking and sports. In addition, we examine whether there are differences between adolescents at sports clubs with versus without an outdoor smoke-free policy (SFP). DESIGN: Qualitative design in the form of focus group interviews. SETTING: Focus group interviews (n=27) were conducted at 16 sports clubs in the Netherlands. Soccer, tennis, field hockey and korfball clubs were included. Focus group discussions were transcribed verbatim and analysed thematically using MAXQDA. PARTICIPANTS: 180 adolescents aged 13-18 years old were included in the study. All participants signed an informed consent form. For participants younger than 16 years, parental consent was required. RESULTS: With respect to smoking in relation to sports, participants had mostly negative beliefs (ie, smoking has a negative effect on health and sports performance), attitudes (ie, sports and smoking are activities that do not fit together; at sports clubs smoking is not appropriate), and social norms (ie, it is not normal to smoke at sports clubs). The same beliefs, attitudes and social norms were expressed by participants at both sports clubs with and without an outdoor SFP. However, argumentation against smoking was more detailed and more consistent among participants at sports clubs with an outdoor SFP. CONCLUSION: Adolescents have negative beliefs, attitudes and social norms with regard to smoking in relationship to sports. Outdoor SFP at sports clubs might reinforce these negative associations. These findings point to the potential importance of sports in the prevention of adolescent smoking.

Coping Strategies Used by Older Adults to Deal with Contact Isolation in the Hospital during the COVID-19 Pandemic.

Due to the COVID-19 pandemic, many older adults have experienced contact isolation in a hospital setting which leads to separation from relatives, loss of freedom, and uncertainty regarding disease status. The objective of this study was to explore how older adults (55+) cope with contact isolation in a hospital setting during the COVID-19 pandemic in order to improve their physical and psychological wellbeing. The realist evaluation approach was used to formulate initial program theories on coping strategies used by (older) adults in an isolation setting. Twenty-one semi-structured interviews with older patients (n = 21) were analysed. This study revealed that both emotion-focused coping strategies as well as problem-focused coping strategies were used by older adults during contact isolation. The study also uncovered some new specific coping strategies. The results have useful implications for hospital staff seeking to improve the wellbeing of older adults in contact isolation in hospitals. Problem-focused coping strategies could be stimulated through staff performing care in a person-centred way. Trust in staff, as part of emotion-focused coping strategies, could be stimulated by improving the relationship between patients and staff.

Adolescents' support for an outdoor smoke-free policy at sports clubs in the Netherlands.

INTRODUCTION: Outdoor smoke-free policies (SFPs) at sports clubs may contribute to the prevention of smoking among adolescents. Adolescents' support for such policy is important to its success. The aim of this study is to explore adolescents' perceptions with regard to an outdoor SFP at sports clubs in the Netherlands. METHODS: Focus group discussions (n=27) were held with 180 participants (aged 13-18 years) at 16 sports clubs. Thematic analysis was used to analyze the data. RESULTS: Participants generally supported an outdoor SFP at sports clubs. Five reasons for this support were reported: 1) children should not be exposed to smoking, 2) smoking and sports (clubs) do not fit together, 3) secondhand smoke is undesirable, 4) an outdoor SFP may enhance a sports club's image, and 5) an outdoor SFP contributes to the prevention of smoking. Some participants voiced considerations against an outdoor SFP, arguing amongst others, that smokers need to be taken into account, and that problems may occur with compliance and enforcement. Support for an outdoor SFP was stronger among participants at clubs with an outdoor SFP than among those without such policy. CONCLUSIONS: This study shows that adolescents generally support an outdoor smoke-free policy at sports clubs. After implementation, the outdoor SFP was generally experienced as a normal practice. These results could encourage sports clubs without an outdoor SFP to become smoke-free as well.

Smoke-Free Sports in The Netherlands: Why Most Sports Clubs Have Not Adopted an Outdoor Smoke-Free Policy.

Background: Outdoor smoke-free policies (SFPs) at sports clubs represent an important new area of tobacco control, as many people, including youth, spend a large portion of their free time participating in sports. Nevertheless, the majority of sports clubs worldwide still have not adopted an outdoor SFP. The aim of this study is to explore the perceptions of key stakeholders at different Dutch sports clubs concerning the adoption of an outdoor SFP. Methods: Semi-structured interviews were held with 41 key stakeholders at seven Dutch sports clubs (in field hockey, football, tennis, or korfball) without an outdoor SFP. A thematic approach was used to analyze the data. Results: The majority of respondents reported considerations that were favorable towards adoption of an outdoor SFP, including expected support from club members, changing social norms with regard to smoking, and few members who smoke. Most of all, respondents valued the protection of children from the harmful effects of smoking. However, they also foresaw a number of problems in case of adoption, including impaired social functioning of the sports club, problems with compliance and enforcement, conflict with smokers' interest, and low priority in club management. Conclusions: Although stakeholders at sports clubs recognize the intrinsic value of an outdoor SFP, they foresee practical problems that are inherent to sports clubs. Adoption could be enhanced by articulating the importance of protecting children from the harmful effects of smoking, referring to 'success stories' at sports clubs that are already smoke-free, and actively involving smokers in the adoption process.

Implementation of an outdoor smoke-free policy at sports clubs: Critical situations and determinants influencing implementation.

BACKGROUND: Outdoor smoke-free policies (SFPs) at sports clubs have significant potential to reduce adolescent smoking. However, the realization of this potential may be strongly dependent on how these policies are implemented in practice. The aim of this study is to explore the perceptions of key stakeholders at different sports clubs in the Netherlands concerning how outdoor SFPs are implemented in practice and which determinants influence implementation. METHODS: Semi-structured interviews were held with 46 key stakeholders at eight Dutch sports clubs (i.e., field hockey, soccer, tennis, korfball) with an outdoor SFP. A thematic approach was used for the analysis of the transcripts. RESULTS: Overall, respondents perceived the implementation of an outdoor SFP at sports clubs as feasible. The SFP is often enforced, people who smoke react positively when they are approached, the SFP has led to less (visible) smoking at the venue, and a nonsmoking norm is reinforced. However, we identified three 'critical situations' in which implementation is less than optimal: 1) when children are not present at the sports club, 2) when alcohol is involved, and 3) when people who smoke relocate to the entrance of the sports club. Several determinants influenced implementation in those critical situations: 1) determinants related to individual smokers and club members (i.e., support, communication towards people who smoke), 2) determinants related to the SFP itself (i.e., clarity of the policy), 3) determinants related to the sports club (i.e., communication of the policy, characteristics of the sports club), and 4) determinants related to the wider community (i.e., change of social norm with regard to smoking, support from local and national organizations). CONCLUSION: Implementation of an outdoor SFP at sports clubs is feasible because there is a high level of support and experiences are mainly positive. Nevertheless, some situations present challenges to compliance and enforcement. We identified a number of determinants that may facilitate implementation of an outdoor SFP at sports clubs.

Evaluation of the Process of Implementing an Outdoor School Ground Smoking Ban at Secondary Schools.

BACKGROUND: Although outdoor smoking bans at school are becoming important, it remains unclear whether successful implementation is feasible and what conditions promote it. Therefore, this study evaluates the implementation process by identifying important factors. METHODS: Interviews were held with directors of 24 secondary schools that had decided to implement an outdoor school ground smoking ban, to identify important factors during implementation. Additionally, observations were made before and (about 4 weeks) after implementation to evaluate adherence to guidelines. Data were analyzed using a thematic approach. RESULTS: During implementation, the following items were important: smoking ban (eg, guidelines), school (eg, policy, enforcement, environmental factors, resources, etc), and external factors (eg, social environment). Four schools were unable to implement the ban, 20 schools implemented the ban but student adherence was low, and at 4 schools, staff members still smoked on school grounds. CONCLUSIONS: Although implementation is feasible, there are challenges. Schools need to apply a phased/dynamic process with ample lead time and clear communication of the policy. Directors should deal with offenders by strictly enforcing the ban and helping them stop smoking. This study offers information to help institutes implement an outdoor smoking ban to further protect adolescents from the harm of smoking.

Impact of an Outdoor Smoking Ban at Secondary Schools on Cigarettes, E-Cigarettes and Water Pipe Use among Adolescents: An 18-Month Follow-Up.

Abstract: The effectiveness of outdoor smoking bans on smoking behavior among adolescents remains inconclusive. This study evaluates the long-term impact of outdoor school ground smoking bans among adolescents at secondary schools on the use of conventional cigarettes, e-cigarettes (with/without nicotine) and water pipes. Outdoor smoking bans at 19 Dutch secondary schools were evaluated using a quasi-experimental design. Data on 7733 adolescents were obtained at baseline, and at 6 and 18-month follow-up. The impact of outdoor smoking bans on 'ever use of conventional cigarettes', 'smoking onset', 'ever use of e-cigarette with nicotine', 'e-cigarette without nicotine', and 'water pipe' was measured. Multilevel logistic regression analysis was used. At schools with a ban, implementation fidelity was checked. At schools where a ban was implemented, at 18-month follow-up more adolescents had started smoking compared to the control condition. No effect of implementation of the ban was found for smoking prevalence, e-cigarettes with/without nicotine, and water pipe use. Implementation fidelity was sufficient. No long-term effects were found of an outdoor smoking ban, except for smoking onset. The ban might cause a reversal effect when schools encounter difficulties with its enforcement or when adolescents still see others smoking. Additional research is required with a longer follow-up than 18 months.

E-cigarette and waterpipe use in two adolescent cohorts: cross-sectional and longitudinal associations with conventional cigarette smoking.

Alternative tobacco products are increasing in popularity. An important question is whether their use is associated with or even leads to conventional smoking, but large-scale (European) studies are scarce. In two cohorts of Dutch adolescents (Cohort I n = 6819, mean age = 13.8 SD = 1.1, 48.2% female; Cohort II n = 2758, mean age = 17.3 SD = 1.8, 61.3% female), we investigated use of electronic (e)-cigarettes with nicotine, e-cigarettes without nicotine and waterpipe. Generalized estimating equation modelling was conducted with ever conventional smoking as the dependent variable (0 = no, 1 = yes) and ever alternative tobacco use as the independent variable, correcting for clustering within schools, age, sex and education in both cohorts. In a subsample (n = 2100), the association between alternative tobacco use at baseline and conventional smoking 6 months later was tested, taking into account smoking propensity (based on personality, susceptibility to peer pressure and smoking intentions). Ever use prevalence was 13.7% for e-cigarettes with nicotine, 29.4% for e-cigarettes without nicotine and 22.1% for waterpipe in Cohort I and 12.3, 27.6 and 45.3% respectively in Cohort II. Ever smokers had tried alternative tobacco products more often than never smokers. Among never-smoking adolescents at baseline, alternative tobacco use predicted ever smoking 6 months later (e-cigarettes with nicotine OR 11.90 95% CI 3.36-42.11; e-cigarettes without nicotine OR 5.36 95% CI 2.73-10.52; waterpipe OR 5.36 95% CI 2.78-10.31). This association was strongest for adolescents with a low baseline risk of smoking. Experimenting with alternative tobacco products is common among Dutch youth. Alternative tobacco use predicts (future) smoking, especially among adolescents with a low smoking propensity.

Effects of tailoring ingredients in auditory persuasive health messages on fruit and vegetable intake.

OBJECTIVE: Health messages can be tailored by applying different tailoring ingredients, among which personalisation, feedback and adaptation. This experiment investigated the separate effects of these tailoring ingredients on behaviour in auditory health persuasion. Furthermore, the moderating effect of self-efficacy was assessed. DESIGN: The between-participants design consisted of four conditions. A generic health message served as a control condition; personalisation was applied using the recipient's first name, feedback was given on the personal state, or the message was adapted to the recipient's value. MAIN OUTCOME MEASURES: The study consisted of a pre-test questionnaire (measuring fruit and vegetable intake and perceived difficulty of performing these behaviours, indicating self-efficacy), exposure to the auditory message and a follow-up questionnaire measuring fruit and vegetable intake two weeks after message exposure (n = 112). RESULTS: ANCOVAs showed no main effect of condition on either fruit or vegetable intake, but a moderation was found on vegetable intake: When self-efficacy was low, vegetable intake was higher after listening to the personalisation message. No significant differences between the conditions were found when self-efficacy was high. CONCLUSION: Individuals with low self-efficacy seemed to benefit from incorporating personalisation, but only regarding vegetable consumption. This finding warrants further investigation in tailoring research.
