In this article, the authors present an empirical example of triangulation in qualitative health research. The Canadian Heart Health Dissemination Project (CHHDP) involves a national examination of capacity building and dissemination undertaken within a series of provincial dissemination projects. The Project's focus is on the context, processes, and impacts of health promotion capacity building and dissemination. The authors collected qualitative data within a parallel-case study design using key informant interviews as well as document analysis. Given the range of qualitative data sets used, it is essential to triangulate the data to address completeness, convergence, and dissonance of key themes. Although one finds no shortage of admonitions in the literature that it must be done, there is little guidance with respect to operationalizing a triangulation process. Consequently, the authors are feeling their way through the process, using this opportunity to develop, implement, and reflect on a triangulation protocol.

Preventing chronic diseases, such as cancer, cardiovascular disease and diabetes, requires complex interventions, involving multi-component and multi-level efforts that are tailored to the contexts in which they are delivered. Despite an increasing number of complex interventions in public health, many fail to be ‘scaled up’. This study aimed to increase understanding of how and under what conditions complex public health interventions may be scaled up to benefit more people and populations.A realist synthesis was conducted and discussed at an in-person workshop involving practitioners responsible for scaling up activities. Realist approaches view causality through the linkages between changes in contexts (C) that activate mechanisms (M), leading to specific outcomes (O) (CMO configurations). To focus this review, three cases of complex interventions that had been successfully scaled up were included: Vibrant Communities, Youth Build USA and Pathways to Education. A search strategy of published and grey literature related to each case was developed, involving searches of relevant databases and nominations from experts. Data extracted from included documents were classified according to CMO configurations within strategic themes. Findings were compared and contrasted with guidance from diffusion theory, and interpreted with knowledge users to identify practical implications and potential directions for future research.Four core mechanisms were identified, namely awareness, commitment, confidence and trust. These mechanisms were activated within two broad scaling up strategies, those of renewing and regenerating, and documenting success. Within each strategy, specific actions to change contexts included building partnerships, conducting evaluations, engaging political support and adapting funding models. These modified contexts triggered the identified mechanisms, leading to a range of scaling up outcomes, such as commitment of new communities, changes in relevant legislation, or agreements with new funding partners.This synthesis applies and advances theory, realist methods and the practice of scaling up complex interventions. Practitioners may benefit from a number of coordinated efforts, including conducting or commissioning evaluations at strategic moments, mobilising local and political support through relevant partnerships, and promoting ongoing knowledge exchange in peer learning networks. Action research studies guided by these findings, and studies on knowledge translation for realist syntheses are promising future directions.Electronic supplementary materialThe online version of this article (doi:10.1186/s12961-016-0158-4) contains supplementary material, which is available to authorized users.

The purpose of this paper is to examine the utility of linking systems between public health resource and user organizations for health promotion dissemination and capacity building, and to identify factors related to the success of linking systems. The design is a parallel-case study using key informant interviews and content analysis of project reports (synthesized qualitative and quantitative data) of three provincial dissemination projects of the Canadian Heart Health Initiative-Dissemination Phase. Each provincial project used linking activities with public health user groups including meetings, skill building, resources, collaboration, networking and research feedback to facilitate capacity building for and implementation of heart health promotion activities. This paper presents empirical examples of linking system designs, activities, and qualitative and quantitative changes in the public health user groups' health promotion capacity, program delivery and sustainability. The findings indicate enhanced health promotion skills, partnerships, resources, infrastructure, and increased programming and sustainability in the targeted public health organizations of all three provincial projects. Identified barriers to the success of linking systems included lack of appropriately skilled personnel, funds, buy-in and leadership. We conclude that linking systems can be flexibly used to build capacity and disseminate health promotion innovations, and suggest conditions for success.

The health promotion best practices literature is imbued with hope for knowledge mobilization, enhanced practice, and improved population health. Given constrained medical care systems, health promotion is key to reducing the significant burden of chronic disease. However, we have seen little evidence of change. This article investigates facilitators of, and barriers to, three stages of health promotion practice in public health organizations, interagency coalitions, and volunteer committees. The article focuses not on what works but why it does or does not, drawing on five case studies within the Canadian Heart Health Initiative. Results indicate that the presence or absence of appropriately committed and/or skilled people, funds and/or resources, and priority and/or interest are the most common factors affecting all stages of health promotion practice. The article extends the literature on internal and external factors affecting health promotion and highlights strategic influences to consider in support of effective health promotion practice.

Cardiovascular diseases are now the world's leading cause of death. To reduce high rates of such preventable premature deaths, evidence-based approaches to heart health promotion must be disseminated across public health systems. To succeed, we must build capacity to disseminate strategies that are practical and effective. However, we know little about such dissemination, and we lack both conceptual frameworks to guide our thinking and appropriate scientific methodologies. This article presents conceptual and analytic frameworks that integrate several approaches to understanding and studying dissemination processes within public health systems. This work is based on the Canadian Heart Health Dissemination Project, a research program examining a national heart health dissemination initiative. The primary focus is the development of a systematic protocol for measuring levels of capacity and dissemination, and determining successful conditions for, and barriers to, capacity and dissemination, as well as the nature of the relationship between these key concepts.

Introduction: Solving complex problems such as preventing chronic diseases introduces unique challenges for the creation and application of knowledge, or knowledge to action (KTA). KTA approaches that apply principles of systems thinking are thought to hold promise, but practical strategies for their application are not well understood. In this paper we report the results of a scan of systems approaches to KTA with a goal to identify how to optimize their implementation and impact.

Background : Research to investigate levels of organisational capacity in public health systems to reduce the burden of chronic disease is challenged by the need for an integrative conceptual model and valid quantitative organisational level measures. Objective: To develop measures of organisational capacity for chronic disease prevention/healthy lifestyle promotion (CDP/HLP), its determinants, and its outcomes, based on a new integrative conceptual model. Methods: Items measuring each component of the model were developed or adapted from existing instruments, tested for content validity, and pilot tested. Cross sectional data were collected in a national telephone survey of all 216 national, provincial, and regional organisations that implement CDP/HLP programmes in Canada. Psychometric properties of the measures were tested using principal components analysis (PCA) and by examining inter-rater reliability. Results: PCA based scales showed generally excellent internal consistency (Cronbach's a = 0.70 to 0.88). Reliability coefficients for selected measures were variable (weighted k(k w ) = 0.11 to 0.77). Indicators of organisational determinants were generally positively correlated with organisational capacity (r s = 0.14-0.45, p,0.05). Conclusions: This study developed psychometrically sound measures of organisational capacity for CDP/HLP, its determinants, and its outcomes based on an integrative conceptual model. Such measures are needed to support evidence based decision making and investment in preventive health care systems.
