Lack of consistency in measurement methods and semantics used for network measures in adolescent health behaviour studies using social network analysis: a systematic review

BACKGROUND

Social network analysis (SNA) is often used to examine how social relationships influence adolescent health behaviours, but no study has documented the range of network measures used to do so. We aimed to identify network measures used in studies on adolescent health behaviours.

METHODS

We conducted a systematic review to identify network measures in studies investigating adolescent health behaviours with SNA. Measures were grouped into eight categories based on network concepts commonly described in the literature: popularity, position within the network, network density, similarity, nature of relationships, peer behaviours, social norms, and selection and influence mechanisms. Different subcategories were further identified. We detailed all distinct measures and the labels used to name them in included articles.

RESULTS

Out of 6686 articles screened, 201 were included. The categories most frequently investigated were peer behaviours (n=201, 100%), position within the network (n=144, 71.6%) and popularity (n=110, 54.7%). The number of measurement methods varied from 1 for 'similarity on popularity' (within the 'similarity' category) to 28 for the 'characterisation of the relationship between the respondent and nominated peers' (within the 'nature of the relationships' category). Using the examples of 'social isolation', 'group membership', 'individuals in a central position' (within the 'position within the network' category) and 'nominations of influential peers' (sub within the 'popularity' category), we illustrated the inconsistent reporting and heterogeneity in measurement methods and semantics.

CONCLUSION

Robust methodological recommendations are needed to harmonise network measures in order to facilitate comparison across studies and optimise public health intervention based on SNA.

Smoking and mental disability : A mixed observational study using a diverse sample of medical-social establishments and services

INTRODUCTION

A multi-center observational study was carried out in ten ESMS, using a mixed methodology (site visits, questionnaire survey, semi-directive group interviews with professionals and individual interviews with users).

PURPOSE OF THE RESEARCH

The aim of this article is to describe the management and prevention of smoking in ESMS for people with mental health disorders, and to characterize and identify the smoking behaviors and representations of ESMS users and the professionals working there.

RESULTS

The study made it possible to distinguish between ESMS in terms of the organization of smoking areas and tobacco prevention initiatives. It also revealed that 37 percent of respondents among the professionals said they smoked tobacco, with some of them explaining that they smoked with users and sometimes gave them cigarettes. With regard to prevention, there was a consensus among professionals that they should help users who wanted to stop smoking. Professionals were divided, however, on the need for more active prevention, citing the users’ freedom and the fact that ESMS are places where people live. Among the users, 47 percent said they were smokers. Of the users who smoked, 55 percent said they wanted to stop. Interviews with the users revealed that twelve of them wanted to quit, with some asking for help and more assistance from professionals.

CONCLUSIONS

This report suggests that intervention research could be developed in ESMS for people with mental health disorders, who could benefit from the smoking prevention actions identified in the facilities and services investigated.

The (De)normalisation of Smoking Among Apprentices: Plurality of Settings, Norms and Vulnerability Levels

When it comes to smoking, apprentices are considered a 'vulnerable' population. They have been the subject of targeted approaches based on the assumption of common characteristics. In contrast to most public health studies, that assume homogeneity of vulnerable groups, this article, based on Lahire's 'theory of the plural individual', aims to examine inter- and intra-individual variability in relation to tobacco exposure. It is based on a secondary analysis of 30 interviews with apprentices in France on the stigma attached to their use in their different living environments. Our study confirms that the family and the Centre de Formation des Apprentis, as a whole, encourage smoking. It also provides a better understanding of the mechanisms by which inequalities are perpetuated (permissive rules, loans and gifts of cigarettes, spillover effects, lack of incentives to quit). Nevertheless, it allows us to observe that, in some families and in some companies, smoking is denormalised, even stigmatised. Several apprentice profiles emerge: those who are protected from tobacco and seem to be able to quit easily; those who are permanently confronted with it and for whom it is difficult to consider quitting or reducing; and those who are confronted with a plurality of norms, who seem ambivalent and whose consumption varies significantly. These results will allow us to adapt the interventions according to the profile of the apprentices and by including their entourage. In particular, it will be necessary to propose a 'go-to' approach that goes beyond the school setting and involves the family and the workplace.

Use of qualitative methods to optimize collaborative practices by highlighting differences in perceptions between professionals: an example of patient education

Interprofessional working must be approached within health promotion interventions using systematic methods to identify areas of suboptimal collaboration. We designed a qualitative study with a purposive sample of seven French therapeutic patient education programs. Semi-structured individual interviews were conducted with 14 healthcare providers and seven clinician leaders (coordinators) involved in patient education. We used the same interview guide and thematic grid regardless of the professional's profile to compare their perceptions on elements affecting outcome, participation and sustainability of programs. Healthcare providers and coordinators addressed non-convergent issues at both ends of a continuum from a micro-level nested in the program delivery to a macro-level corresponding to the structured implementation and sustainability of the program. Meso-level issues featured convergent perspectives. Our methodology could be used at the level of health services in a health system to provide a complete recovery of stakeholders' perspectives (without "blind spots" from one stakeholder or another). In our study, we focused on patient education in the French health system and pointed out possible considerations to optimize the functioning of programs. Such considerations include specific training plan development, encouraging reflection on the content and use of initial assessment, leading sessions in pairs to save on work time, and communication on the ins and outs of organizational imperatives that require healthcare providers' contributions.

What contextual features affect the outcome and sustainability of therapeutic patient education interventions?

BACKGROUND

Therapeutic patient education interventions are influenced by contextual factors. Therefore, describing the context is crucial to understanding how it can affect therapeutic patient education interventions and contribute to outcomes. We aimed to identify the contextual features that may affect the outcome and sustainability of therapeutic patient education interventions from a healthcare professional perspective.

METHODS

Semi-structured individual interviews were conducted with healthcare professionals involved in 14 therapeutic patient education interventions covering different chronic conditions (e.g., kidney and cardiovascular diseases, chronic pain, diabetes, obesity). Interviews were recorded and fully transcribed. We followed a general inductive approach to identify themes from healthcare professionals' discourse to properly capture their perception.

RESULTS

Saturation was achieved with 28 interviews with 20 nurses, 6 dieticians, one physiotherapist and one psychologist. The average therapeutic patient education experience was 7 years. Identified contextual features clustered in 5 main themes: 1) conditions for the development of the intervention (genesis of the program: Who and what prompted it?; supports; content development; legislative framework); 2) integration of the program (in the healthcare pathway or the environment, relationship with the institution or local environment); 3) teamwork cohesion, interaction and integration with the environment (exchanges, cohesion of the team); 4) sustainability of the program; and 5) patient and healthcare professional contextual factors.

CONCLUSION

New insights into contextual features that may be involved in therapeutic patient education interventions are represented in a framework based on the Medical Research Council evaluation framework. These features need to be addressed in studies of therapeutic patient education interventions and could help healthcare professionals build more effective interventions within the context. However, describing a list of elements of the context is not enough; analyses should also focus on how the contextual elements might affect an intervention and how they interact.

A Systematic Review of Qualitative Studies on Factors Associated With Smoking Cessation Among Adolescents and Young Adults

OBJECTIVE

To summarize findings from qualitative studies on factors associated with smoking cessation among adolescents and young adults.

DATA SOURCES

We searched Pubmed, Psychinfo, CINAHL, Embase, Web of Science, and SCOPUS databases, as well as reference lists, for peer-reviewed articles published in English or French between January 1, 2000, and November 18, 2020. We used keywords such as adolescents, determinants, cessation, smoking, and qualitative methods.

STUDY SELECTION

Of 1724 records identified, we included 39 articles that used qualitative or mixed methods, targeted adolescents and young adults aged 10-24, and aimed to identify factors associated with smoking cessation or smoking reduction.

DATA EXTRACTION

Two authors independently extracted the data using a standardized form. We assessed study quality using the National Institute for Health and Care Excellence checklist for qualitative studies.

DATA SYNTHESIS

We used an aggregative meta-synthesis approach and identified 39 conceptually distinct factors associated with smoking cessation. We grouped them into two categories: (1) environmental factors [tobacco control policies, pro-smoking norms, smoking cessation services and interventions, influence of friends and family], and (2) individual attributes (psychological characteristics, attitudes, pre-quitting smoking behavior, nicotine dependence symptoms, and other substances use). We developed a synthetic framework that captured the factors identified, the links that connect them, and their associations with smoking cessation.

CONCLUSIONS

This qualitative synthesis offers new insights on factors related to smoking cessation services, interventions, and attitudes about cessation (embarrassment when using cessation services) not reported in quantitative reviews, supplementing limited evidence for developing cessation programs for young persons who smoke.

IMPLICATIONS

Using an aggregative meta-synthesis approach, this study identified 39 conceptually distinct factors grouped into two categories: Environmental factors and individual attributes. These findings highlight the importance of considering both environmental and individual factors when developing smoking cessation programs for young persons who smoke. The study also sheds light on self-conscious emotions towards cessation, such as embarrassment when using cessation services, which are often overlooked in quantitative reviews. Overall, this study has important implications for developing effective smoking cessation interventions and policies that address the complex factors influencing smoking behavior among young persons.

Mediating effect of sleep in the association between social media use and mental health among French adolescents during the COVID-19 sanitary crisis

OBJECTIVE/BACKGROUND

Social media use could have deleterious effects on mental health through short sleep duration and poor sleep quality among adolescents. This study aimed to investigate the mediating role of both sleep duration and sleep quality in the association between social media use and mental health among adolescents.

PATIENTS/METHODS

We used cross-sectional data collected from adolescents in the EXIST pilot project conducted during COVID-19 pandemic. Adolescents self-reported wellbeing (WEMWBS), anxiety and depression (HADS) as mental health outcomes. We used ad-hoc questionnaires to assess social media use during weekdays and weekend days, and sleep duration and quality. Mediation analyses were carried out following Baron and Kenny's method, using adjusted linear regression models.

RESULTS

A total of 340 adolescents (13.5 ± 0.6 years, 45.3 % girls) were included. Greater social media use, poorer sleep quality, and shorter sleep duration were associated with poorer mental health. Greater social media use was associated with poorer sleep quality only during the weekend days. The total effect of social media use during weekend days on anxiety (β = 2.54; 95%CI [-1.59; 6.68]) was significantly conveyed through sleep quality (β = 1.22; 95%CI [0.17; 2.62]; mediated proportion = 48.0 %) and duration (mediated proportion = 46.8 %). Mediated proportions ranged from 12.5 % to 20.6 % for wellbeing and depression. Mediating effects were not evident during weekdays.

CONCLUSIONS

Sleep duration and quality mediated the association between social media use and mental health among adolescents during weekend days but not weekdays. Our findings highlight the importance of promoting healthy social media habits, especially during periods of increased reliance on digital platforms, such as COVID-19 pandemic.

A Smoking Prevention Intervention Among Young People in an Online Community Game: Results from a Pilot Randomized Controlled Trial

Background: Innovative methods for smoking prevention interventions need to be investigated to increase attractiveness, access hard-to-reach populations, and increase effectiveness. We studied the feasibility and immediate effects of an intervention to reinforce norms and behaviors of young people related to antismoking, integrated into a popular online community game. Methods: A pilot randomized controlled trial was conducted through the HABBO online community. The intervention group was exposed to repeated discussion sessions with small groups of peer players and two facilitators once a week for 1 month (four sessions), inside the game. The control group had access to antismoking information websites. Process indicators (attractiveness, participation) and immediate outcomes (norms and intentions with regard to smoking) were assessed by questionnaire. Results: One hundred sixteen players were invited to participate in the intervention; 10 did not meet eligibility criteria, 30 were allocated to the intervention group, and 76 to the control group. Median age was 23. Twenty-four percent were not in education, employment, or training. A median of eight players attended each session and the median number of exchange chats by session was 399; 70% of chat time was occupied by the players. Twenty players attended all four sessions. Immediate norms, representations, and intentions were evaluated in 39 players and showed small differences between groups. Conclusion: Delivering and evaluating a smoking prevention intervention in an online game is feasible. In the targeted online community game, the intervention was attractive and allowed the delivery of innovative interventions to audiences with diverse social profiles. Long-term effects, sustainability, and evaluation methodology are discussed.

Creation and validation of the pictorial ecological momentary well-being instrument (EMOWI) for adolescents

PURPOSE

Adolescence is characterized by the ongoing maturation of emotion-regulation skills and increased emotional reactivity. There is a need for a measurement tool suitable to the Ecological Momentary Assessment methodology, to better capture within-day variations in well-being, and provide fine-grained data that can help understand how environments, behaviors, and health intersect. This paper presents the development and evaluation of the Ecological MOmentary Well-Being Instrument for adolescents, designed for use in EMA.

METHODS

A mixed-methods study was conducted, using both qualitative and quantitative approaches, to develop and assess the EMOWI. A literature review, pictorial production by graphic designers, and qualitative interviews with French and Canadian professionals and adolescents helped design and evaluate the scale face validity. Quantitative evaluation of dimensionality, reliability, and validity was conducted in two samples of French 8th graders.

RESULTS

The resulting 8-item EMOWI showed excellent face validity. Confirmatory factor analysis supported a single factor hypothesis (RMSEA = 0.072). Internal consistency (Cronbach's alpha = 0.85) and intraday test-retest reliability (ICC = 0.83) were high. Correlations with existing scales were consistent with preset hypotheses. Ceiling effects were evidenced for all items, yet not on the global score. Quantitative estimations were similar for the verbal and pictorial versions, but qualitative findings argued in favor of the pictorial version.

CONCLUSION

The 8-item pictorial EMOWI is a short and innovative instrument to measure momentary well-being in adolescents aged 12 to 17 years. Its strong psychometric properties and its acceptability among adolescents make it an excellent candidate instrument for the Ecological Momentary Assessment of well-being in this population.

Stigmatisation et santé publique : le côté obscur des interventions anti-tabac

Tobacco control strategies, considered legitimate and effective, are rarely the subject of critical analysis in France. This is specifically true with regard to their potentially harmful effects, particularly against people who continue to smoke. This article introduces this debate, focusing on the potentially stigmatizing effects of anti-smoking policies. It has been attested by numerous international studies, and by a study in France, that the general process of tobacco denormalization has led to the stigmatization of smokers who then may be subject to discrimination. To the extent that smoking is now concentrated in the most disadvantaged socio-economic populations in France, the latter are thus more exposed to stigma. While underscoring the need to develop targeted interventions against them, this article also warns and calls for vigilance regarding the potential iatrogenic effects of these interventions. It is therefore necessary to develop research and evaluations on this subject in order to accurately measure the effects of these interventions, particularly in terms of stigmatization and self-stigma, and to ensure that public health actors do not generate more problems than they solve.

The Natural Course of Cigarette Smoking among Adolescent Daily Smokers in France and Quebec

Objective:

To describe the natural course of cigarette smoking and nicotine dependence (ND) over 1-year in daily smokers ages 15 to 17 living in different social contexts.

Method:

Cigarette smoking and ND indicators were measured at baseline and 3- and 12-months thereafter among 95 daily smokers with a total of 123 observations from the Nicotine Dependence in Teens (NDIT) Study in Quebec, Canada, and in 111 daily smokers from the TABagisme chez les ADOlescents (TABADO) Study in Lorraine, France.

Results:

NDIT and TABADO participants initiated smoking a mean (SD) of 3.9 (1.6) and 3.7 (2.0) years prior to baseline, respectively. Despite baseline differences in age, sex, age at initiation, number of cigarettes smoked per day and social context, 85% of participants in both samples reported cravings and responded “yes” to “felt like you really need a cigarette”. Mean (SD) number of cigarettes smoked per day increased from 9.4 (8.1) to 11.8 (8.0) over 1 year in NDIT (adjusted mean difference (95% CI) = 2.4 (0.8, 3.0)), and from 11.5 (6.5) to 13.5 (6.7) in TABADO (adjusted mean difference (95% CI) = 2.0 (0.8, 3.1)). However, most ND indicators in both samples were stable over time and cessation was infrequent.

Conclusion:

Despite notable differences across samples, the natural course of cigarettes smoked per day, ND symptoms and cessation was similar, suggestive of an underlying biologic rather than social process. To quit, adolescents who smoke daily will likely need (pharmacologic) intervention to counter the biological mechanisms underpinning ND, as well as complementary strategies targeting the social context such as creating social environments favoring cessation success.

Population health intervention research: what is the place for pilot studies?

Background

An international workshop on population health intervention research (PHIR) was organized to foster exchanges between experts from different disciplines and different fields.

Aims

This paper aims to summarize the discussions around one of the issues addressed: the place or role of pilot studies in PHIR. Pilot studies are well-established in biomedical research, but the situation is more ambiguous for PHIR, in which a pilot study could refer to different purposes.

Methods

The workshop included formal presentations of participants and moderated discussions. An oral synthesis was carried out by a rapporteur to validate by expert consensus the key points of the discussion and the recommendations. All discussions have been recorded and fully transcribed.

Discussion

PHIR generally addresses complex interventions. Thus, numerous tasks may be required to inform the intervention and test different aspects of its design and implementation. While in clinical research the pilot study mainly concerns the preparation of the trial, in PHIR the pilot study focuses on the preparation of both the intervention and the trial. In particular, pilot studies in PHIR could be used for viability evaluation and theory development.

Recommendations from the workshop participants

The following recommendations were generated by consensus from the workshop discussions: i) terms need to be clarified for PHIR; ii) reporting and publication should be standardized and transparency should be promoted; iii) the objectives and research questions should drive the methods used and be clearly stated; iv) a pilot study is generally needed for complex intervention evaluation and for research-designed programs; and v) for field-designed programs, it is important to integrate evaluability assessments as pilot studies .

Conclusion

Pilot studies play an important role in intervention development and evaluation. In particular, they contribute to a better understanding of the mechanisms of intervention and the conditions of its applicability and transferability. Pilot studies could therefore facilitate evidence-based decisions about design and conduct of main studies aimed to generate evidence to inform public health policy.

Which design to evaluate complex interventions? Toward a methodological framework through a systematic review

BACKGROUND

Evaluation of complex interventions (CI) is challenging for health researchers and requires innovative approaches. The objective of this work is to present the main methods used to evaluate CI.

METHODS

A systematic review of the scientific literature was conducted to identify methods used for the evaluation of CI. We searched MEDLINE via PubMed databases for articles including an evaluation or a pilot study of a complex intervention, published in a ten-year period. Key-words of this research were ("complex intervention*" AND "evaluation").

RESULTS

Among 445 identified articles, 100 research results or protocols were included. Among them, 5 presented 2 different types of design in the same publication, thus our work included 105 designs. Individual randomized controlled trials (IRCT) represented 21.9% (n = 23) of evaluation designs, randomized clinical trials adaptations 44.8% (n = 47), quasi -experimental designs and cohort study 19.0% (n = 20), realist evaluation 6.7% (n = 7) and other cases studies and other approaches 8.6% (n = 9). A process/mechanisms analysis was included in 80% (n = 84) of these designs.

CONCLUSION

A range of methods can be used successively or combined at various steps of the evaluation approach. A framework is proposed to situate each of the designs with respect to evaluation questions. The growing interest of researchers in alternative methods and the development of their use must be accompanied by conceptual and methodological research in order to more clearly define their principles of use.

[Socioeconomic profile and smoking among adolescents in vocational training]

BACKGROUND

Targeted interventions among vulnerable youth populations represent an important approach to the reduction of health inequalities. We must, however, ensure that impacts are not unequally distributed according to the range of resources available to them. We explore these concerns among youth in vocational training to be enrolled in a smoking cessation intervention by describing (1) their socio-economic profile and (2) the association between their socioeconomic characteristics, their smoking practices, and key factors that could be targeted in interventions.

METHODS

A total of 234 young people aged 15-20 years were recruited in three centers in the Lorraine region in France in 2016-2017 as part of the Social Network and Tobacco Cessation (Réseau social et sevrage tabagique [RESIST]) study. We measured participants' socio-economic characteristics using their parents' education and occupational grade. We examined the associations of these characteristics with participants' smoking habits, intention to quit, nicotine dependence, presence of smokers in their network, and representation of a young smoker. We examined the associations between variables with bivariate tests depending on the nature of the variables.

RESULTS

Participants were more likely to be from a socio-professional background more modest than the national average (56% versus 33%), but still exhibited considerable socioeconomic variability. Smoking status did not vary significantly according to the educational level of the participants' parents (from 52% to 57%, P=0.78) or occupational grade (from 52% to 58%, P=0.35). Compared to participants whose parents had completed a professional or pre-university degree, participants with parents in the lowest education category were less likely to report not intending to quit (P=0.01) and more likely to report seriously considering to quit in the next six months (P=0.03) and to have already tried to quit but failed (P=0.01).

CONCLUSION

It is tempting to define youth in vocational training as a homogeneous group, especially when they share the same school environment, employment status, and income. Our results, however, highlight substantial variability in their socioeconomic profiles and smoking characteristics. Researchers are encouraged to further consider these equity issues to contribute to the reduction of health inequalities.

Exploration of the experiences, practices and needs of health promotion professionals when evaluating their interventions and programmes

INTRODUCTION

The aim of this study was to describe the practices of health promotion professionals when evaluating interventions and their transferability and to identify these professionals' needs in relation to a tool that will guide them during monitoring and evaluation.

METHOD

A survey was carried out among health promotion actors, which focussed on the interventions they had carried out.

RESULTS

Of the 1017 organisations (covering the whole of France) approached, 246 responded to the survey. More than 60% of the respondents had faced difficulties during the construction of the process evaluation, and more than 50% had faced difficulties during its implementation. These difficulties related to data collection, the conception or choice of indicators, criteria and relevant evaluation tools, and lack of time and personnel. Eighty per cent reported that they had carried out the same action in different places and had been faced with two main obstacles, namely budget and environment. Recognition, positive evaluation, existing collaborations and willingness to work in partnership plus the capacity to adapt to local contexts were identified as factors fostering transferability.

DISCUSSION

Despite the many recommendations available, constructing and carrying out evaluations is not systematic. Actors are confronted with many difficulties, which could be overcome with an IT tool that incorporates the actors' suggestions during its development.

Addressing complexity in population health intervention research: the context/intervention interface

Background

Public health interventions are increasingly being recognised as complex and context dependent. Related to this is the need for a systemic and dynamic conception of interventions that raises the question of delineating the scope and contours of interventions in complex systems. This means identifying which elements belong to the intervention (and therefore participate in its effects and can be transferred), which ones belong to the context and interact with the former to influence results (and therefore must be taken into account when transferring the intervention) and which contextual elements are irrelevant to the intervention.

Discussion

This paper, from which derives criteria based on a network framework, operationalises how the context and intervention systems interact and identify what needs to be replicated as interventions are implemented in different contexts. Representing interventions as networks (composed of human and non-human entities), we introduce the idea that the density of interconnections among the various entities provides a criterion for distinguishing core intervention from intervention context without disconnecting the two systems. This differentiates endogenous and exogenous intervention contexts and the mediators that connect them, which form the fuzzy and constantly changing intervention/context interface.

Conclusion

We propose that a network framework representing intervention/context systems constitutes a promising approach for deriving empirical criteria to delineate the scope and contour of what is replicable in an intervention. This approach should allow better identification and description of the entities that have to be transferred to ensure the potential effectiveness of an intervention in a specific context.

Evaluation of a knowledge transfer scheme to improve policy making and practices in health promotion and disease prevention setting in French regions: a realist study protocol

Background

Evidence-based decision-making and practice are pivotal in public health. However, barriers do persist and they relate to evidence properties, organisations and contexts. To address these major knowledge transfer (KT) issues, we need to rethink how knowledge is produced and used, to enhance our understanding of decision-making processes, logics and mechanisms and to examine the ability of public health services to integrate research findings into their decisions and operations. This article presents a realist evaluation protocol to assess a KT scheme in prevention policy and practice at local level in France.

Methods/design

This study is a comparative multiple case study, using a realist approach, to assess a KT scheme in regional health agencies (ARS) and regional non-profit organisations for health education and promotion (IREPS), by analysing the configurations contexts/mechanisms/outcomes of it. The KT scheme assessed is designed for the use of six reviews of systematic reviews concerning the following themes: nutrition, alcohol, tobacco smoking, physical activity, emotional and sexual life and psychosocial skills. It combines the following activities: supporting the access to and the adaptation of scientific and usable evidences; strengthening professionals’ skills to analyse, adopt and use the evidences in the course of their practices and their decision-making process; facilitating the use of evidence in the organisations and processes. RAMESE II reporting standards for realist evaluations was used.

Discussion

The aims of this study are to experiment and characterise the factors related to the scheme’s ability to enable public health stakeholders to address the challenges of KT and to integrate scientific knowledge into policy and practice. We will use the realist approach in order to document the parameters of successful KT strategies in the specific contexts of preventive health services in France, while seeking to determine the transferability of such strategies.

[Complexity: concept and challenges for public health interventions]

Introduction: Since 2000, the notion of “complex interventions” has been emerging in the health research field. “Complex interventions” and “complexity” are commonly used terms, but they are generally not defined. Conceptual ambiguities persist concerning the notion of complexity. The objective of this exploratory review is to characterize the notion of complexity: What is complexity? Where does this notion come from and what does it cover? What are the consequences of complexity in the health field?Methods: To clarify the concept of complexity, a narrative review was conducted in the fields of humanities and social science, managerial economics, psychology and healthcare.Results: The concept of complexity, that can be attributed to Edgar Morin, has been the subject of appropriations, adaptations, and operations in multiple areas. Complexity consists of understanding the factors influencing individual decisions. In the field of healthcare, the concept of complexity is used more pragmatically and is defined by objective characteristics of interventions (defined as complex) or their contexts for the practical purposes of evaluation.Discussion: The notions of complexity and complex interventions have implications for researchers and users of the results of research. In particular, the notion of complexity is designed to provide a better understanding of the mechanism of effectiveness of interventions, support transferability and use by actors and decision-makers.

Early Psychological Preventive Intervention For Workplace Violence: A Randomized Controlled Explorative and Comparative Study Between EMDR-Recent Event and Critical Incident Stress Debriefing

This randomized controlled trial study aims to investigate the efficacy of an early psychological intervention called EMDR-RE compared to Critical Incident Stress Debriefing on 60 victims of workplace violence, which were divided into three groups: 'EMDR-RE' (n = 19), 'CISD' (n = 23), and 'delayed EMDR-RE' (n = 18). EMDR-RE and CISD took place 48 hours after the event, whilst third intervention was delayed by an additional 48 hours. Results showed that after 3 months PCLS and SUDS scores were significantly lower with EMDR-RE and delayed EMDR-RE compared to CISD. After 48 hours and 3 months, none of the EMDR-RE-treated victims showed PTSD symptoms.

[Reflections on the evaluation and funding of complex public health interventions]

In France, in a context of growing health inequalities, the need for action on life settings and, more broadly, on the social determinants of health (SDH), requires a contribution from health promotion research. Today's challenge is not only to design interventions tailored to contexts and actively targeting SDH, but also to develop innovative evaluation strategies of these complex interventions. A group of researchers and representatives from funding agencies met in Paris on june 2nd, 2014 to discuss current experiences conducted in France. The debates yielded five conclusions: (i) the context of the intervention must be considered as one of its active ingredients, (ii) evaluation must be guided by a sound intervention logic (iii) randomized controlled trials cannot capture the complexity of the environment and evaluation must be designed using alternative models, including process evaluation, (iv) interventional research should be collaborative, or co-constructed, (v) public health training should cover the diversity of evaluative methods. The conclusions described here, in the context of France, stress that to address these challenges, funding agencies, researchers and stakeholders should further engage in discussions concerning the conduct of interventional research, evaluation and implementation of complex public health interventions.

[AFSSAPS 2005 recommendations have not modified the way parents take care of children's fever]

INTRODUCTION

Fever in children is frequent. Often mild, initial care is the parents' responsibility: medicinal treatments and medical consultations. Unfortunately, the efficiency of parental care is poor. Therefore, in 2005 the AFSSAPS updated its recommendations. One and 6 years after publication of the guidelines, this study rates their impact by describing and comparing parents' knowledge and behavior when faced with fever in their children.

MATERIAL AND METHODS

This survey was conducted in families whose children were attending preschool in and near Metz (France) in 2006 and 2012. The same questionnaire was given to assess the knowledge, care, and symptoms of serious fever. The results were processed based on the number of children in the family and the family's socioeconomic category.

RESULTS

In 2006, 1038 questionnaires were distributed and 1273 in 2012. The fever threshold was not better known in 2012. Bathing and uncovering children remained the predominant physical methods used. Treatment was based on the use of ibuprofen and alternating treatments. However, the conditions of administering medication were well known to parents. The causes and motives for consultation were not better understood in 2012 however. The main source of information was physicians.

DISCUSSION

The message disseminated since 2005 has not been efficient. Its complexity has not eradicated old beliefs and inappropriate parental practices. A campaign based on a brief, simple message has to be organized, providing better chances of being assimilated by the public. Medical practices should be standardized.

Stakeholders' perceptions of transferability criteria for health promotion interventions: a case study

Background

The effects of health promotion interventions are the result not only of the interventions themselves, but also of the contexts in which they unfold. The objective of this study was to analyze, through stakeholders’ discourse, the characteristics of an intervention that can influence its outcomes.

Methods

This case study was based on semi-structured interviews with health promotion stakeholders involved in a regional program (PRALIMAP). General hypotheses on transferability and on how the intervention is presumed to produce its effects were used to construct an interview guide. Interviews were analyzed using thematic coding.

Results

Twenty-three stakeholders were interviewed. Results showed stakeholders made few references to population and environment characteristics. Three themes emerged as significant for the stakeholders: implementation modalities and methodology, modalities used to mobilize actors; and transferability-promoting factors and barriers.

Conclusion

Our work contributes to a better understanding not only of transferability factors, but also of stakeholders’ perceptions of them, which are just as important, because those perceptions themselves are a factor in mobilization of actors, implementation, and transferability.

[A tool to facilitate transferability of health promotion interventions: ASTAIRE]

The complexity of health promotion interventions raises the problem of the transferability of their results from one setting to another. A tool has been developed and validated: ASTAIRE (AnalySe de la Transférabilité et Accompagnement à l'adaptation des InteRventions en promotion de la santE) (analysis of the transferability and support to adaptation of health promotion interventions). The purpose of this article is to present the French language version of this tool to enable French-speaking stakeholders and scientists to adopt this tool and use it for the purposes of development of evidence-based health promotion. ASTAIRE comprises 23 transferability criteria classified in four categories: population, environment, implementation, transfer support. It is composed of two grids, one for reporting of initial interventions according to transferability criteria and the other to analyse the comparability of settings and to facilitate transfer. This tool is designed to support the choice of the intervention most adapted to the setting and to facilitate transfer of this intervention. Use of this tool can promote the development of evidence-based approaches according to an adaptive logic of interventions. Collective use of this tool in project logics can distinguish the key functions of interventions, which determine their efficacy and which must be transferred, from aspects related to the form, which can be adapted to the setting.

Evaluating complex interventions: perspectives and issues for health behaviour change interventions

OBJECTIVE

Health behaviour change interventions (HBCIs), used in health education, health promotion, patient education and psychotherapy areas, are considered complex interventions. The objective of this article is to discuss the value and limitations of using randomised clinical trials (RCTs) to asses HBCIs.

METHODS

A scoping review of the literature was conducted to identify the main challenges of using RCTs for evaluating HBCIs. The issues were illustrated by case studies selected from research conducted by our multidisciplinary team.

RESULTS

In complex interventions, effects are produced not only by the intervention, but are strongly linked to context. Issues relating to transferability of results are therefore critical, and require adjustments to the RCT model. Sampling bias, biases related to the experimental conditions and biases due to the absence of double-blindness were examined and illustrated by case studies.

CONCLUSION

The results underline the importance of a multidisciplinary approach. They call for adapted or alternative evaluation models that overcome the limitations of RCTs.

A tool to analyze the transferability of health promotion interventions

Background

Health promotion interventions are often complex and not easily transferable from one setting to another. The objective of this article is to present the development of a tool to analyze the transferability of these interventions and to support their development and adaptation to new settings.

Methods

The concept mapping (CM) method was used. CM is helpful for generating a list of ideas associated with a concept and grouping them statistically. Researchers and stakeholders in the health promotion field were mobilized to participate in CM and generated a first list of transferability criteria. Duplicates were eliminated, and the shortened list was returned to the experts, scored for relevance and grouped into categories. Concept maps were created, then the project team selected the definitive map. From the final list of criteria thus structured, a tool to analyze transferability was created. This tool was subsequently tested by 15 project leaders and nine experts.

Results

In all, 18 experts participated in CM. After testing, a tool, named ASTAIRE, contained 23 criteria structured into four categories: population, environment, implementation, and support for transfer. It consists of two tools—one for reporting data from primary interventions and one for analyzing interventions’ transferability and supporting their adaptation to new settings.

Conclusion

The tool is helpful for selecting the intervention to transfer into the setting being considered and for supporting its adaptation. It also facilitates new interventions to be produced with more explicit transferability criteria.

[Management of smoking in the perioperative period: survey of practices amongst anaesthetists in Lorraine]

INTRODUCTION

Evidence shows that smoking leads to more perioperative complications. Smoking cessation before surgery reduces this postoperative morbidity. The French Society of Anaesthesia and Intensive Care published recommendations on this subject in 2005. We wanted to assess knowledge and practice amongst anaesthetists in Lorraine as regards the management of smoking in the perioperative period.

METHODS

We conducted an internet-based survey of 365 anaesthetists in the Lorraine region during November and December 2011. At the same time, we also surveyed patients attending pre-assessment clinic at the CHU hospital, Nancy.

RESULTS

Half the practitioners surveyed were aware of the 2005 guidelines. Most pre-assessment clinics do not display posters warning of the perioperative hazards of smoking. The need for smoking cessation advice as a bare minimum is acknowledged by 47.9% of experienced practitioners; 76.3% of anaesthetists claim to offer advice occasionally, frequently or systematically. On the other hand, only 17% of the patients surveyed report receiving such advice.

CONCLUSION

Despite published guidelines on the benefits of smoking cessation prior to surgery, Lorraine anaesthetists fail to systematically advise their patients in this regard. We believe there is a need to improve the management of these patients, either through the development of smoking cessation protocols locally or through patient referral to a specialised clinic.

Transferability of interventions in health education: a review

BACKGROUND

Health education interventions are generally complex. Their outcomes result from both the intervention itself and the context for which they are developed. Thus, when an intervention carried out in one context is reproduced in another, its transferability can be questionable. We performed a literature review to analyze the concept of transferability in the health education field.

METHODS

Articles included were published between 2000 and 2010 that addressed the notion of transferability of interventions in health education. Articles were analyzed using a standardized grid based on four items: 1) terminology used; 2) factors that influenced transferability; 3) capacity of the research and evaluation designs to assess transferability; and 4) tools and criteria available to assess transferability.

RESULTS

43 articles met the inclusion criteria. Only 13 of them used the exact term "transferability" and one article gave an explicit definition: the extent to which the measured effectiveness of an applicable intervention could be achieved in another setting. Moreover, this concept was neither clearly used nor distinguished from others, such as applicability. We highlight the levels of influence of transferability and their associated factors, as well as the limitations of research methods in their ability to produce transferable conclusions.

CONCLUSIONS

We have tried to clarify the concept by defining it along three lines that may constitute areas for future research: factors influencing transferability, research methods to produce transferable data, and development of criteria to assess transferability. We conclude this review with three propositions: 1) a conceptual clarification of transferability, especially with reference to other terms used; 2) avenues for developing knowledge on this concept and analyzing the transferability of interventions; and 3) in relation to research, avenues for developing better evaluation methods for assessing the transferability of interventions.

[Tobacco use characteristics among apprentices in Vocational Centers]

BACKGROUND

Most smokers start smoking during adolescence and become dependent before 20 years old. In France, vocational trainees are a population not much explored. The objective of our study is to present tobacco use characteristics among apprentices in Vocational Centers (VC).

METHODS

This cross-sectional exhaustive study covered 1814 students (among whose 943 smokers) entering in a 1st year of the eight participating Vocational Centers in the Lorraine region (Eastern France, 2.3 million inhabitants, 16,500 vocational trainees), during the school years 2007-2008 and 2008-2009. Data collection concerned the sociocultural environment, tobacco use habits, degree of dependency to tobacco and co-addictions.

RESULTS

Among the study population, 52.0% declared they were smokers among whom 89.4% daily smokers, and 5.7% were ex-smokers. The average age of tobacco use initiation was 12.1 years (standard deviation [SD]=2.1) and the average age at inception of regular cigarette smoking was 13.8 years (SD=1.6). Current consumption of the smokers was 12.8 cigarettes per day (SD=7.8). The average score of smoking addiction was 6.1 (SD=2.8), according to the Hooked On Nicotine checklist test (score from 0 to 10=strongly dependent). Finally, 37.1% of students (58.9% among smokers) smoked or have smoked cannabis.

CONCLUSION

The high prevalence of smoking in Vocational Centers, the early start of tobacco use and the high tobacco consumption among apprentices show that they are overexposed compared to the general population of adolescents. In addition, these young people are already dependant to tobacco use. This underlines the need of specific measures dedicated to this population that amounts to 361,500 individuals in France.

TABADO: "evaluation of a smoking cessation program among adolescents in vocational training centers": study protocol

Background

Most of the efforts to reduce teenagers' tobacco addiction have focused on smoking prevention and little on smoking cessation. A smoking cessation program (TABADO study), associating pharmacologic and cognitive-behavioural strategy, on a particularly vulnerable population (vocational trainees), was developed. This study aims to evaluate the efficacy of the program which was offered to all smokers in a population aged 15 to 20 years in Vocational Training Centers (VTC). This paper presents the TABADO study protocol.

Methods

The study is quasi-experimental, prospective, evaluative and comparative and takes place during the 2 years of vocational training. The final population will be composed of 2000 trainees entering a VTC in Lorraine, France, during the 2008-2009 period. The intervention group (1000 trainees) benefited from the TABADO program while no specific intervention took place in the "control" group (1000 trainees) other than the treatment and education services usually available. Our primary outcome will be the tobacco abstinence rate at 12 months.

Discussion

If the program proves effective, it will be a new tool in the action against smoking in populations that have been seldom targeted until now. In addition, the approach could be expanded to other young subjects from socially disadvantaged backgrounds in the context of a public health policy against smoking among adolescents.

Trial registration

Clinical trial identification number is NTC00973570.
