Basic Criteria, Models, and Indicators of Intersectoral Collaboration in Health Promotion: A Scoping Review

Background: In this study, the basic criteria, models, and indicators of intersectoral collaboration in health promotion were investigated to facilitate the implementation of collaboration. Methods: This scoping review was conducted using datasets of Embase, Web of Science, Scopus, and PubMed, and search engines of Google, Google Scholar, and ProQuest. Results: 52 studies were included, and 32 codes in Micro, Meso, and Macro level, were obtained. Micro-level criteria had the highest frequency. Among the models used in the reviewed studies, social network analysis, Diagnosis of Sustainable Collaboration, Bergen, and logic models had the highest frequency. Among the indicators studied, the number of participants and the level of collaboration as well as its sustainability were the most frequent indicators. Conclusion: The findings identified the most important and widely used criteria, models, and indicators of intersectoral collaboration in health promotion which can be useful for decision-makers and planners in the domain of health promotion, in designing, implementing, and evaluating collaborative programs.


Introduction
Various population health approaches are available, including health promotion, disease prevention, and disease treatment. The health promotion approach is applied without patient identification, encompasses the entire population, makes individuals resilient, and creates environments that support the community health (1). Health promotion as action requires cooperation and investment for achieving a common goal, and as a process prepares health prerequisites such as peace, shelter, education, food, income, sustainable ecosystems, sustainable resources, and social justice and equity through public policy-making (2). Therefore, it should be considered as a collective action that focuses on empowering people to have control over their social health determinants (3).
Intersectoral collaboration has entered the domain of health through the Alma Ata Declaration in Kazakhstan in 1978. This declaration referred to the provision of comprehensive health services while considering economic and social issues (4). In 1980, Ottawa Declaration explained further need for more intersectoral actions to achieve better health outcomes. After the introduction of the concept of social determinants of health in 1990, efforts to develop intersectoral collaboration were expanded. Moreover, by holding a conference on intersectoral actions by WHO in 1997 and Bangkok's declaration in 2000, the need for collaboration between various sectors for health promotion was further emphasized. For this purpose, a number of European countries attempting to implement intersectoral collaboration faced some problems. As a result, in 2006, the European Union (EU) proposed "Health in All Policies" (HiAP) as a guide for developing, implementing, and evaluating intersectoral policies (5). For example, The Public Health Act (2000) in Quebec obliged all organizations to consult with the Minister of Health and Social Services before setting the rules or regulations, which had a significant effect on health (6). Proponents of the cross-sectoral approach argue that successful public health measures to control infectious, emerging, cardiovascular, and cancer diseases can be learned (7). In developing countries, the intersectoral collaboration strategy is not well implemented (8). There is a scatter in the criteria, models and indicators used in different studies that may to make policy makers and planners slow in understanding its flow. A scoping review aimed to investigate the scope and subject area of a field, summarize the findings of studies, and determine the gap in the existing literature on a subject (9).

Methods
This scoping review was conducted using Arksey and O'Malley framework (2005) (definition of research questions, identification of the related studies, and selection of the studies, tabulating the se-lected studies, and the summarization, and reporting of results). According to the main research question, three category keywords, including intersectoral collaboration and its different spectra, health promotion and its related dimensions, and model, index, and criteria (and their equivalents) were explored in Web of Science, PubMed, Scopus, and Embase databases. In addition, Google Scholar, Google, and ProQuest databases were also explored for up to the first 200 cases. In order to keep the article short, the search method in Scopus database was given as an example. The complete search of the database is attached in the additional files.

Inclusion/Exclusion Criteria
Original articles, review articles, and reports on health promotion published by the WHO written in English and reviewed regardless of time constraints were included. In terms of subject, articles examining the basic criteria, models, or indicators of intersectoral collaboration in health promotion were included (date of search: May 7, 2019). Studies on the challenges and opportunities for intersectoral collaboration in the domain of health and those on services other than promotion services (disease prevention, treatment, and rehabilitation) as well as editorials, commentaries, and letters were excluded. To ensure that the related studies were not lost from the beginning of the study until the time of writing the article, an alert was defined for each database to inform the researcher if a new article was published in this scope. The alert for the main databases was controlled until the preparation of the final version of the article.

Extraction of Results
At first, the results of the search in databases were entered into Endnote X7 software. In the second step, the first screening was performed independently by two authors. After reading the title and abstract of the articles, the related studies that met the inclusion criteria were identified, and their full text was downloaded. In the second screening, the articles selected from the previous stage were marked with five stars (much-related articles) in Endnote. Papers whose inclusion was not decided upon were marked with four stars, and other suspicious items with three stars. The third author reviewed the three-and four-star articles and determined their status.
The intersectoral collaboration criteria were manually and thematically extracted.by this steps: Studying the full text of all articles, initial encoding of the data, Identifying themes for codes that had a common field, Reviewing and modifying the themes, naming the themes, providing the extracted themes (10). In the final step, studies were deeply restudied, and the title and year of the study, study area, type of study, and the criteria, indicators and models mentioned in the study were summarized (Additional file 1: Summary of included studies). In order to ensure that all articles retrieved from the study databases were analyzed, the selected studies were manually reference-checked, and related articles were added. After entering the details of the studies into Excel, descriptive characteristics of the studies were reported.

Search results
9842 articles were obtained. After the removal of duplicates, 4943 articles remained, and the abstract of 404 articles met the inclusion criteria. After obtaining the full text of the articles from the first screening, 52 articles met the inclusion criteria ( Fig. 1).

Descriptive characteristics of studies
The studies were mostly qualitative that conducted in 2015 in countries such as the USA, the Netherlands, and Canada. The main scope of the studies was public health (27 articles), mental health (6 articles), school health (6 articles), water and food health (3 articles), and physical activity (3 articles) (Fig. 2).

Discussion
In terms of collective actions in health promotion, several studies have been published as original articles or review studies, the discrepancies between the results of that and the present study can be due to their focus on determining effective factors in the collaboration, study period (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015), the studied databases (MEDLINE, CINAHL, Science Direct, and Psych INFO), and the research questions (26). Another review analyzed the results of studies which investigated supportive and inhibitive factors for collaboration in the promotion of health through the Bergen model. However, there are some differences between this study and the present study in terms of the study period (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015), some of the studied databases (CINAHL, ERIC, MEDLINE, and Psych INFO), and the research questions (10). Scoping review was conducted using datasets of Embase, Web of Science, Scopus, and PubMed, and search engines of Google, Google Scholar, and ProQuest. Developed countries such as the US, the Netherlands, and Canada conducted more studies on intersectoral collaboration in the domain of health, which may be due to the greater attention of the central government of these countries to the role of health and its impact on the rules governing various organizations. From the last decade (2010 onwards), attention has been paid to studies on intersectoral collaboration in the domain of health, which may have been due to a paradigm shift towards different approaches to health (biomedicine viewpoint to health towards more comprehensive approaches such as health in all policies). Among common indicators used in this area, some indicators such as the number of participants, the level of collaboration, and sustainability in the collaboration were the most frequent indicators (11, 17, 19, and 27). Because of the application of these indicators at different studies, they can be useful for whom they want to evaluate their collaboration in health fields. Examining the models employed in the studies showed that there were some general similarities between the models, but there were also some differences in the segmentation of the components of the models. As a result, in the DISC model, which was one of the most commonly used models, five components of external factors, context, change management, project management, and sustainability/support were considered. In another study, this model was implemented with two institutional components (sociopolitical context and organizational commitment) and organizational dimension (leadership, task management, capacity building, communication structure, and visible results) (11). The Tukman model (21), had many similarities with the stages of team development (forming, storming, norming, and performing). The Bergen model (10,15), examined the structure of intersectoral collaboration at three levels of input, process, and outcome. In the Himmelman model, the defined criteria referred to a variety of collaborations (cooperation, collaborating, networking, and coordinating) (16). The collective impact approach, examined five criteria: putting the subject on the agenda, a common measurement system, synergistic activities, communication, and structural support for the success of collective actions. The criteria used in the act for life model (20) had a high degree of similarity with those extracted from the present study, (continuous engagement of participants, clear intersectoral communication channels, and understanding of the culture of other sectors, etc.). In the social network analysis model, criteria of network membership, collaboration in the network, and the role of centrality in collaborative sub-networks were taken into consideration (28). This model is employed to understand communication networks using variables such as density measurement, closeness centrality, betweenness centrality, and Eigenvector centrality. The multisectoral collaboration model is composed of six consecutive stages. A strong motivation to convince the stakeholders for cross-sectoral action, A clear definition of the situation and the assessment method, innovations related to the area under consideration, the implementation of designed mechanisms, monitoring and evaluation of process, synergy and strengthening the dialogue between stakeholders , and ultimately learn from the successes and failures resulting from collective actions (29). The system analysis model has four consecutive stages: The first stage is the identification of stakeholders' network through exploring political documents, government sites, and interviewing key actors. In the second stage, the schematic plan of the relative status of stakeholders identified in the stakeholders' network is prepared. The third stage involves the description of relationships between stakeholders. Finally, the fourth stage encompasses the review and finalization of the schematic model of the relationships among stakeholders (23). The logic model was used in two studies (24,25).
In this model first, the facilitators or barriers are listed, and then the processes, techniques, tools, and measures of the program under study are determined. The output is the result of the direct implementation of the program, which forms the third part of the model. Outcomes modifying the behavior, attitude, knowledge, skill, or expected level of performance of the program are the fourth part of the program. The final impact of the last part of this model can be organizational or community changes, presented as increased capacity, change in policy, etc. Comparative evaluation of the models used in intersectoral actions in health promotion revealed that the social network analysis, DISC, Bergen, and logic models were the most commonly used models in health promotion, which may be due to the comprehensiveness of the criteria mentioned in them. For brevity, from each level, three criteria that had the highest frequency in the studies were discussed. In this study, to ease the understanding of the criteria and their implementation, all the criteria repeated in the studies were categorized into three levels of micro, meso, and macro (30). This model applied based on a research that conducted on Intersectoral Action for Health and Many of the criteria used in this study were consistent with that (31). These three levels complement each other, and failure at one level leads to failure at other lev-els, therefore, by considering these criteria, planners and policymakers can prevent incorrect actions to implement collaborative actions. Micro-level is a level in which involving actors are important. In this stage, social interaction among stakeholders, capacity building for framing relationships are stated (31). 39.4% of the criteria were at the micro-level, and dimensions of the boundary spanner leadership, communication structure, and knowledge and information sharing were the most frequently used criteria in this area. The features of a boundary spanner leader include the ability to manage boundaries (knowledge sharing and understanding of different perspectives), the creation of a shared context (the resources integration and mobilization by defining shared vision and values), and the discovery of new boundaries (the creation of creative ideas (32). Open and face-to-face communication can be used to build trust-based relationships with other sectors (33,34). Effective communication will only be achieved by building trust between various governmental and nongovernmental organizations, holding regular meetings, and allocating sufficient time to it (35). Sharing information and effective communication have been reported effective in reducing disagreement and other forms of conflict between different sectors (36). At the meso-level, issues such as strengthening management and leadership, trust-building, and a shared understanding of problems are considered. It refer to structure and process inside and between actors. At this level, some criteria can be defined at organizational culture levels and refers to the government's actions and structures. 24.8% of the criteria were at this level. The engagement of different stakeholders, provision of resources, and monitoring the relationship between collaborators had respectively the highest frequency at this level. A clear definition of contributors, the inclusion/exclusion criteria, and acceptance criteria is important for stakeholder's engagement (37). Resource provision include money, materials, and equipment (10). and methods used for making decisions on financial, mechanisms, and tools that are used to ensure financial integrity, should be de-termined (37). Monitoring contributors' perceptions of the collaboration can provide valuable information on how to adjust relationships. Moreover, assessment of the quality of collaboration at different levels, is essential for predicting future problems and responding to existing problems (10). The third level is the macro level that implies to ideologies and dominant values, this level refers to governmental and national layers. Some criteria such as structure, organization, market, and government measures are taken into account. The main motivator at this level is politics, defined as a legal issue or a statement of values and principles related to goals, by individuals, communities, or societies (31). Macro level contains 35.82% of the criteria. Comprehensive supports, sharing goals, and shared vision, had respectively the highest frequency in the studies.
Since the process of intersectoral collaboration often requires a new structure, and accordingly, new resources, therefore adequate financial support for these efforts must be considered (38). In Sweden, Quebec, and South Australia, financial incentives could act as a facilitator for the implementation of health program in all policies (28). The goals of collaboration should not be opposed to the contributors' authorities (39), but it must be predetermined, accessible, measurable, and understandable for all actors through a common language (40). Creating a long-term perspective from the beginning of and during the collaboration process is necessary to create a shared perception (41).
Overall, the results of this study were consistent with those of other studies, with the difference that, in this study, the basic criteria for intersectoral collaboration in the area of health promotion were categorized, and related models and indicators were identified.

Limitations
only studies with basic criteria for intersectoral collaboration in the domain of health or those with a specific model or index were included, so studies that investigated challenges, barriers, strategies might have been missed, justified according to the main objectives of this study. Furthermore, some criteria that were not repeated in other studies might have been excluded from this study.

Conclusion
There is a lack of comprehensive research that tell us what should we do when we want to start Intersectoral collaboration in the health promotion field. In this study, the basic criteria, models, and indicators for intersectoral collaboration in the domain of health promotion were identified and categorized, that can help planners and decision-makers to use of them at shared actions and models and indicators can also be applied to assess achievements.
