The Diffusion of Smoking: Association Between School Tobacco Policies and the Diffusion of Adolescent Smoking in 38 Schools in 6 Countries.

Social network research has evidenced the role of peer effects in the adoption of behaviours. Little is known, however, about whether policies affect how behaviours are shared in a network. To contribute to this literature, we apply the concept of diffusion centrality to school tobacco policies and adolescent smoking. Diffusion centrality is a measure of centrality which refers to a person's ability to diffuse a given property-in our case, smoking-related behaviours. We hypothesized that stronger school tobacco policies are associated with less diffusion centrality of smoking on school premises and of smoking in general. A whole network study was carried out in 2013 and 2016 among adolescents (n = 18,805) in 38 schools located in six European cities. Overall, diffusion centrality of smoking in general and of smoking on school premises significantly decreased over time. Diffusion centrality of smoking significantly decreased both in schools where the policy strengthened or softened over time, but for diffusion of smoking on school premises, this decrease was only significant in schools where it strengthened. Finally, stronger school tobacco policies were associated with lower diffusion centrality of smoking on school premises and of smoking in general, though to a lesser extent. With such policies, smoking may, therefore, become less prevalent, less popular, and less clustered, thereby lowering the risk of it spreading within networks in, and even outside the school.

Key dimensions of collaboration quality in mental health care service networks.

Appropriate care delivery for patients with severe mental illness (SMI) requires a high level of collaboration quality between primary, mental health, and social care services. Few studies have addressed the interpersonal and inter-organizational components of collaboration within one unique study setting and it is unclear how these components contribute to overall collaboration quality. Using a comprehensive model that includes ten key indicators of collaboration in relation to both components, we evaluated how interpersonal and inter-organizational collaboration quality were associated in 19 networks that included 994 services across Belgium. Interpersonal collaboration was significantly higher than inter-organizational collaboration. Despite the internal consistency of the model, analysis showed that respondents perceived a conflict between client-centered care and leadership in the network. Our results reveal two approaches to collaborative service networks, one relying on interpersonal interactions and driven by client needs and another based on formalization and driven by governance procedures. The results reflect a lack of strategy on the part of network leaders for supporting client-centered care and hence, the persistence of the high level of fragmentation that networks were expected to address. Policy-makers should pay more attention to network formalization and governance mechanisms with a view to achieving effective client-centered outcomes.

School tobacco policies and adolescent smoking in six European cities in 2013 and 2016: A school-level longitudinal study.

Assessment of the effectiveness of school tobacco policies (STPs) in reducing adolescent smoking remains inconclusive. Previous studies took insufficient account of different dimensions of STPs, the different views of students and staff, and policy changes over time. This study assessed how a multidimensional STP, as perceived by students and staff, was associated with adolescent smoking over time in six European cities. The SILNE and SILNE-R surveys were conducted among students (n = 18,502) and staff (n = 438) in 38 schools in 2013 and 2016. Three dimensions (comprehensiveness, enforcement, and communication) were assessed and we calculated total STP scores. Multilevel logistic regressions estimated associations of STPs with adolescent smoking on and just outside school premises and with weekly smoking. Further analyses estimated associations between 2013 and 2016 STP changes and smoking outcomes in 2016, controlling for STP and smoking prevalence in 2013. On average, there were few increases in STP scores over time. Greater STP enforcement, as perceived by students, was associated with lower odds of weekly smoking (OR:0.93, 95%CI:0.89-0.97) and of smoking on school premises (OR:0.80, 95%CI:0.72-0.90). Higher total STP scores were associated with lower odds of smoking on school premises (OR:0.76, 95%CI:0.67-0.86), but not of smoking just outside premises or smoking weekly. Greater increases in STP scores over time were associated with lower odds of smoking on school premises in 2016 (OR:0.65, 95%CI:0.47-0.89). Well-enforced STPs may help reduce adolescent smoking at school. Schools should be supported in adopting comprehensive policies that also extend to the surroundings of their premises.

Youth Access to Cigarettes Across Seven European Countries: A Mixed-Methods Study.

BACKGROUND: Despite widespread age-of-sale restrictions on tobacco, adolescents continue to obtain cigarettes and experiment with smoking. This mixed-methods study aimed to understand how European adolescents access cigarettes and how the policy context may influence this process, using a realist evaluation approach. This is the first study to assess access to cigarettes across various European contexts. METHODS: A survey of 4104 students was combined with qualitative data from focus groups among 319 adolescents aged 14-19 across seven European countries. Data were synthesized to explore mechanisms via which young people obtain cigarettes despite age-of-sale restrictions. RESULTS: While purchasing cigarettes from supermarkets was widely regarded as difficult, many participants purchased cigarettes from noncompliant retailers (often in smaller shops or cafes). Other contra-mechanisms included circumventing age checks, proxy purchases, and/or social sources. Dominant forms of access differed across the seven contexts, with direct purchases more common where perceived enforcement was low (eg, Belgium) and proxy purchases more important where perceived enforcement of age-of-sale laws was high (eg, Finland). The effectiveness of age-of-sale restrictions in reducing youth access appears to be influenced by a range of contextual factors including retailer compliance, the availability of vending machines, and the specific minimum age-of-sale. CONCLUSIONS: Our findings illustrate the relevance of programme theory in understanding the contra-mechanisms that undermine the effectiveness of age-of-sale laws in discouraging youth smoking. Young people's access to cigarettes could be further limited by addressing these contra-mechanisms, including an increase in the legal sales age (particularly in Belgium), banning vending machines, and strengthening enforcement. IMPLICATIONS: Despite widespread implementation of age-of-sale laws, a substantial proportion of minors continue to access cigarettes. Young people use a number of contra-mechanisms to circumvent age-of-sale restrictions. These include accessing cigarettes via social sources, proxy sales or by circumventing age checks. Our findings show that in contexts where perceived enforcement of age-of-sale restrictions is high, young people are more reliant on irregular forms of access such as proxy sales. Young people's access to cigarettes may be further reduced by policy interventions that address these contra-mechanisms-for example, banning vending machines, strengthening enforcement of age-of-sale laws, and increasing the minimum age-of-sale.

'[ ] the situation in the schools still remains the Achilles heel.' Barriers to the implementation of school tobacco policies-a qualitative study from local stakeholder's perspective in seven European cities.

School tobacco policies (STPs) are a crucial strategy to reduce adolescents smoking. Existing studies have investigated STPs predominantly from a school-related 'insider' view. Yet, little is known about barriers that are not identified from the 'schools' perspective', such as perceptions of local stakeholders. Forty-six expert interviews from seven European cities with stakeholders at the local level (e.g. representatives of regional health departments, youth protection and the field of addiction prevention) were included. The analysis of the expert interviews revealed different barriers that should be considered during the implementation of STPs. These barriers can be subsumed under the following: (i) Barriers regarding STP legislature (e.g. inconsistencies, partial bans), (ii) collaboration and cooperation problems between institutions and schools, (iii) low priority of smoking prevention and school smoking bans, (iv) insufficient human resources and (v) resistance among smoking students and students from disadvantaged backgrounds. Our findings on the expert's perspective indicate a need to enhance and implement comprehensive school smoking bans. Furthermore, collaboration and cooperation between schools and external institutions should be fostered and strengthened, and adequate human resources should be provided.

Smoking beliefs across genders, a comparative analysis of seven European countries.

BACKGROUND: Most European countries have seen a decrease in the prevalence of adolescent smoking. This decrease has, however, been patterned by gender. Girls' smoking rates have now overtaken boys' in many European countries. The two genders may not, however, share the same smoking beliefs and this could explain differences between the genders in smoking prevalence. We describe gender differences in smoking beliefs and investigate variations between countries, along with their gender context. METHODS: In 2016, we conducted the SILNE R study (Smoking Inequalities Learning from Natural Experiments - Renew) in 55 schools located in seven European countries: Belgium, Italy, The Netherlands, Portugal, Finland, Ireland, and Germany. We surveyed 12,979 students aged 14-16 years (50% were girls). We classified smoking beliefs into four categories: positive individual, positive social, negative individual, and negative social beliefs. We expected girls to score higher on the last three of those categories and we hypothesized that countries with a more gender-equal culture would have less gender difference in beliefs about smoking. RESULTS: One out of two smoking beliefs differed significantly between genders. Negative social beliefs were more common in girls, while beliefs about the dating-related aspects of smoking were more common in boys. We identified Germany and Belgium as the only countries with no gender differences in any of the belief scales. No correlation was found, however, between these scales and the Gender Inequality Index. CONCLUSIONS: In some countries, gender-specific interventions might be implemented; however, two opposing strategies might be used, depending on whether such programs are aimed at boys or girls.

Effectiveness of Health and Social Service Networks for Severely Mentally Ill Patients' Outcomes: A Case-Control Study.

Mental health and social care services networks aim to provide patients with continuity of care and support their recovery. There is, however, no conclusive evidence of their effectiveness. Since 2011, Belgium has been implementing a nation-wide reform of mental health care by commissioning service networks. Using a case-control design, we assessed the reform's effectiveness for continuity of care, social integration, quality of life, and re-hospitalization for 1407 patients from 23 networks. Greater reform exposure was associated with a slight improvement in continuity of care, but not with other outcomes. We concluded that service networks alone do not affect patient-level outcomes.

Same-Sex Friendship, School Gender Composition, and Substance Use: A Social Network Study of 50 European Schools.

BACKGROUND: Other-sex friendship (girls with boy friends, boys with girl friends) has been associated with substance use, but how the gender composition of schools influences substance use has not been known. OBJECTIVES: We analyzed the influence of other-sex friendship on substance use and took into account the proportion of each gender group at the schools, and hypothesized that other-sex friendship is associated with higher levels of substance use and that schools with a majority of males have higher levels of use than female-majority schools. METHODS: In 2013, a social network survey was carried out in six European cities. In each city, schools were selected and 11,015 adolescents (aged 14-16) were recruited (participation rate = 79.4%). We collected data on smoking, binge drinking, cannabis use, and peer group composition. RESULTS: Other-sex friendship was associated with smoking, binge drinking, and cannabis use for girls and with smoking for boys. Substance use was more frequent in schools with a majority of males. Conclusions/Importance: Adolescent girls are best protected from substance use if they are in gender-balanced schools, but in same-sex friendship. This offers new perspectives on gender mixing at school. In schools with a majority of boys, more attention should be paid to girls, and gender-specific health promotion programs should be implemented. This European study is the first to take into account both individual (other-sex friendship) and contextual (gender composition of schools) gender interactions. It confirms previous studies on other-sex friendship, while shedding light on the influence of gender-normative contexts on substance use.

Assessment of the priority target group of mental health service networks within a nation-wide reform of adult psychiatry in Belgium.

BACKGROUND: Belgium is currently implementing a nation-wide reform of mental health care delivery based on service networks. These networks are supposed to strengthen the community-based supply of care, reduce the resort to hospitals, and improve the continuity of care. They are also intended to supply comprehensive care to all adult mental health users. It is unclear, however, if one single model of network can target the needs of the whole adult population with mental health problems. METHODS: In 2011, ten networks were commissioned and assessed. Networks included a total of 635 services of different types. Services were asked to select 10 users by systematic sampling and to state whether these users were considered as a priority for care in the network. Sociodemographic, social integration level, diagnoses, and psycho-social functioning variables were also collected. RESULTS: Two thousand four hundred ninety users were included, and 1564 were given priority for network care. Priority was higher for men than for women (69.9 % versus 56.2 %), and for non-nationals than for Belgians (72.6 % versus 61.9 %). Users were designated priority when they had poor psycho-social functioning (HoNOS > 17, OR = 3.15, p < 0.001), personality disorder or schizophrenia (OR = 1.54, p < 0.001), and a medium level of social integration (SIX = [2,3], OR = 1.57, p < 0.001). Less socially integrated patients (SIX < 1, OR = 0.53, p < 0.001) and users of community and social services were less likely to be selected. CONCLUSION: Although the reform was intended for the whole population of adults with mental health problems, the users selected have a profile of severe mentally-ill users with social deprivation and poor social functioning. Policy may have been over-ambitious trying to address the whole population with one single type of service network. The actual selection process of users makes it less likely that the reform will achieve all its objectives.

Implementing a Nation-Wide Mental Health Care Reform: An Analysis of Stakeholders' Priorities.

Belgium has recently reformed its mental health care delivery system with the goals to strengthen the community-based supply of care, care integration, and the social rehabilitation of users and to reduce the resort to hospitals. We assessed whether these different reform goals were endorsed by stakeholders. One-hundred and twenty-two stakeholders ranked, online, eighteen goals of the reform according to their priorities. Stakeholders supported the goals of social rehabilitation of users and community care but were reluctant to reduce the resort to hospitals. Stakeholders were averse to changes in treatment processes, particularly in relation to the reduction of the resort to hospitals and mechanisms for more care integration. Goals heterogeneity and discrepancies between stakeholders' perspectives and policy priorities are likely to produce an uneven implementation of the reform process and, hence, reduce its capacity to achieve the social rehabilitation of users.

Use of generic social services and social integration of patients with a severe mental illness in Belgium: Individual and services network determinants.

BACKGROUND: Patients with severe mental illnesses (SMI) have low levels of social integration, which could be improved if they used social services. To our knowledge, however, the extent to which they use generic social services remains unknown. AIMS: We assessed the extent to which patients with SMI use generic social services and the factors that may drive that usage. METHOD: In 2014, we carried out a multi-setting clustered survey of patients with severe mental disorders (n = 1,019, participation rate = 71%) and of services (n = 517, participation rate = 53%) in 19 networks of services, covering most of Belgium. On the one hand, we asked patients, amongst other, about their health condition, their social integration in the community, and their use of social services of different types. On the other hand, we asked each service to report on its relationships with other services in the services networks. RESULTS: On average, patients' use of generic social services within the previous 6 months was low (6%-16%), with the exception of administrative services. There were few differences in usage according to the severity of patients' symptoms, but some differences according to gender and age were observed. Social integration was improved when generic social services were more central in the networks. CONCLUSIONS: We suggest that generic social services should be more central in mental health services networks.

The effect of school smoke-free policies on smoking stigmatization: A European comparison study among adolescents.

The increasing denormalization of smoking by tobacco control policies and a normative smoke-free climate may shift power towards adolescent non-smokers. It is unclear, however, how common stigmatization of smokers is among adolescents or how stigmatization relates to the denormalization of smoking in their school and social environment. This paper aims to measure (1) whether stigmatization among European adolescents varies according to smoking status and socioeconomic position (SES), and (2) whether stigmatization is greater in school environments in which smoking is denormalized (i.e. those with low smoking rates and strong school tobacco policies). Data on 12,991 adolescents were collected in 55 schools in seven European countries (SILNE R-survey, 2016/17). We applied Stuber's adapted scale of perceived stereotyping and discrimination towards smokers to smoking status and five variables indicating a power shift towards non-smokers: the school's tobacco control policy (STP) score, the percentage of adolescents in the school who smoke, parents' level of education, students' academic performance, and the percentage of their friends who smoke. Multilevel regressions were applied to the global score for perceived stigmatization. Discrimination against smokers and stereotyping of smokers were frequently reported. Smokers reported less 'perceived stigmatization of smoking' than non-smokers (Beta = -0.146, p < 0.001). High-SES students reported stereotyping and discrimination more frequently than lower-SES students. The perception of stigmatization was lower among students whose academic performance was poor (Beta = -0.070, p < 0.001) and among those who had friends who smoked (Beta = -0.141, p < 0.001). Stigmatization was lower in schools with greater exposure to smoking and was not associated with the school's STP score. Perceived stigmatization of smoking is common among European adolescents. Smokers themselves, however, perceive stigmatization less often than non-smokers. Strong school tobacco policies do not increase stigmatization, but a social environment that is permissive of smoking decreases perceived stigmatization.

The visibility of smoking in Europe and its relationship with youth's positive beliefs about smoking.

OBJECTIVES: To determine adolescent-reported visibility of smoking in different public and private spaces in Europe and associations between smoking visibility and beliefs about the benefits of smoking. METHODS: We used SILNE-R cross-sectional survey data (2016/2017) of 10,798 14-16-year-old students from 55 secondary schools in seven European cities. Respondents reported for private and public spaces whether they had seen others smoke there in the last 6 months. Beliefs about the benefits of smoking were measured on a 7-item scale; higher scores indicated more positive beliefs. Multilevel linear regression analyses determined associations while controlling for potential confounders and stratifying by smoking status. RESULTS: Most students reported observing others smoke in public spaces, especially at train/bus stations (84%). Positive beliefs about smoking of never smokers were positively associated with seeing others smoke in train/bus stations and leisure/sports facilities, but not at home, a friend's home, restaurants or bars, when fully adjusted. Associations were of similar magnitude for ever smokers. CONCLUSIONS: Smoking in several public places is highly visible to adolescents. Reducing this visibility might weaken positive beliefs that adolescents have about smoking.

The association between smoke-free school policies and adolescents' anti-smoking beliefs: Moderation by family smoking norms.

BACKGROUND: Smoke-free school policies (SFSPs) may influence adolescents' smoking through the development of anti-smoking beliefs. We assessed which types of anti-smoking beliefs (health, social and societal) are associated with SFSPs and whether these associations were different for adolescents in smoking permissive versus prohibitive families. METHODS: Survey data was collected in 2016-2017 from 10,980 adolescents between 14-16 years old and 315 staff in 55 schools from seven European cities. We separately measured adolescent-perceived SFSP and staff-reported SFSP at the school-level. Associations between SFSP and anti-smoking health, social and societal beliefs were studied using multi-level logistic regression, adjusting for demographics and school-level smoking prevalence. We tested for interactions between family norms and SFSP, and estimated associations for adolescents in permissive and prohibitive families, respectively. RESULTS: Adolescent-perceived SFSP was not significantly associated with anti-smoking health (OR:1.08, 95%CI:0.94-1.25), social (OR:0.89, 95%CI:0.75-1.04) and societal beliefs (OR:1.15, 95%CI:0.99-1.33). Staff-reported SFSP were associated with anti-smoking health beliefs (OR:1.12, 95%CI:1.01-1.24), but not with social (OR:0.94, 95%CI:0.83-1.07) or societal beliefs (OR:1.02, 95%CI:0.90-1.14). Most results were comparable between adolescents in smoking prohibitive and permissive families. However, in smoking prohibitive families, adolescent-perceived SFSP were associated with societal beliefs (OR:1.24, 95%CI:1.06-1.46), but not in permissive families (OR:1.06, 95%CI:0.90-1.25). Also, in smoking permissive families, staff-reported SFSP were associated with more pro-smoking social beliefs (OR:0.83, 95%CI:0.72-0.96), but not in prohibitive families (OR:1.05, 95%CI:0.92-1.16). CONCLUSIONS: We found evidence that SFSP are associated with some anti-smoking beliefs, but more so among adolescents from smoking prohibitive families than from permissive families.

A social network analysis of substance use among immigrant adolescents in six European cities.

BACKGROUND: Social integration and the health of adolescents with a migration background is a major concern in multicultural societies. The literature, however, has paid little attention to the wider determinants of their health behaviours, including the composition of their social networks. The aim of this study was to describe the composition of adolescents' social networks according to migration background, and to examine how social networks are associated with substance use. METHOD: In 2013, the SILNE study surveyed 11,015 secondary-school adolescents in 50 schools in six European cities in Belgium, Finland, Germany, Italy, the Netherlands, and Portugal, using a social network design. Each adolescent nominated up to five of their best and closest friends. Migration status was defined as first-generation migrants, second-generation migrants, and speaking another language at home. We computed two groups of network structural positions, the centrality of individual adolescents in networks, and the homophily of their social ties regarding migration (same-migration). Multilevel logistic regression was used to model the association between network structural position and smoking, alcohol use, and cannabis use. RESULTS: Compared with non-migrant adolescents, adolescents with migration backgrounds had similar relationship patterns. But almost half their social ties were with same-migration-background adolescents; non-migrants had few social ties to migrants. For adolescents with a migration background, a higher proportion of social ties with non-migrants was associated with increased use of cannabis (OR = 1.07, p = 0.03) and alcohol (OR = 1.08, p < 0.01), but not with increased smoking (p = 0.60). Popular migrant adolescents were at less risk of smoking, alcohol use, and cannabis use than popular non-migrant adolescents. CONCLUSION: Homophily of social ties by migration background is noticeable in European schools. The tendency of migrant adolescents to have same-migration social ties may isolate them from non-migrant adolescents, but also reduces their risky health behaviours, in particular cannabis and alcohol use.
