Introduction
Translation, dissemination, implementation, and improvement (TDII) research is a rapidly growing field that seeks to understand and develop systematic strategies to enhance the uptake of evidence-based practices (EBPs) that improve health-care delivery [Reference Aarons1–Reference Rabin4]. Health sciences researchers in multiple disciplines, including psychology, health services, epidemiology, social work, and medicine, are gradually recognizing the importance of using TDII methodologies to translate evidence into practice [Reference Brownson, Colditz and Proctor3, Reference Woolf5]; however, researchers face significant barriers to working together and engaging in TDII research.
Interdisciplinarity—defined as interdisciplinary collaboration among stakeholders based in different institutions, ideologies, and methodological approaches—has been identified as critical to successfully overcoming barriers to the uptake of EBPs [Reference Brownson2, Reference Curran6–Reference Proctor8]. The purpose of this manuscript is to discuss barriers to and facilitators of interdisciplinarity in TDII drawn from a multidisciplinary expert panel. By addressing this emerging emphasis, we seek to contribute to solutions to integrate various disciplines and settings that engage in team-based and cross-disciplinary research [Reference Börner9, Reference Fiore10], ultimately enhancing interdisciplinary TDII research.
Conceptual Framework
We rely on Stokols’ interdisciplinary team science framework (Fig. 1) to identify barriers and facilitators related to ideological, structural, and organizational dimensions of effective collaboration across disciplinary teams. Stokols’ work is informed by the science of team science (SciTS). SciTS is concerned with understanding multilevel factors that facilitate or hinder a wide range of collaborative, team-based research efforts [Reference Börner9, Reference Stokols11] and seeks to understand conditions, processes, and outcomes associated with successes and failures of interdisciplinary team science initiatives [Reference Stokols11]. The fields of SciTS and TDII research are complementary; both focus on intrapersonal, interpersonal, organizational and institutional, physical and environmental, societal and political, and technological contextual factors that contribute to understanding the impact of interventions on team effectiveness, health intervention outcomes, or both. SciTS can be used to understand how to build effective team performance and interdisciplinary collaboration [Reference Stokols11, Reference Emmons, Viswanath and Colditz12] that may lead to effective translation of TDII research findings into practice [Reference Emmons, Viswanath and Colditz12].
Materials and Methods
The work presented here arose from formal presentations and small group discussions during the 2014 Southern California Dissemination, Implementation, and Improvement Science Symposium, sponsored by the University of California, Los Angeles Clinical Translational Science Institute; the University of Southern California Clinical and Translational Science Institute; and Kaiser Permanente. The goal of the day-long symposium was to accelerate the quantity and quality of TDII science programs and activities.
Participants were 12 senior and junior investigators, research fellows, leaders of local health-care delivery systems and public health agencies, and research partners in community-based organizations in Los Angeles. Participants represented a wide variety of disciplines including health services (7), sociology (3), and psychology (2). Participants also reported conducting research at different research institutions, including the US Department of Veteran Affairs, research universities (University of California, Los Angeles; University of Southern California; and Azusa Pacific University), and research centers in medical settings. Most participants were located in a medical organization.
Breakout sessions were moderated by a faculty member and a fellow who were selected based on their expertise and experience in the discussion topic. The session followed a semistructured question and answer format with open-ended questions posed by session leaders. The session began with initiation questions and moved to an iterative process in which new questions were developed and asked during the session. The session was audio recorded and transcribed, and written notes from attendees and session leaders were synthesized and reviewed for accuracy by the 2 session leaders. Semistructured questions used to initiate discussion included (1) How do we define interdisciplinary? (2) What are some challenges and barriers to working in interdisciplinary teams? (3) What are some potential solutions or facilitators to overcome these barriers? The identified topics spanned ideological (disciplinary orientations that prevent collaboration), structural (workplaces that isolate or limit collaboration), and organizational (poor leadership and communication that limit collaboration) domains, to an extent conforming to the Stokols et al.’s [Reference Stokols11] framework of contextual factors that influence transdisciplinary collaboration.
Summary of Findings
Participants broadly defined discipline as an organized body of knowledge and methods. As such, the group identified >25 disciplines with direct relevance to building TDII research. Although participants represented fewer than half of those disciplines, they highlighted the importance of reaching out to scientists from those disciplines to strengthen interdisciplinary connections to develop TDII research in health and health care. Table 1 lists some of the stakeholders that participants said should be included in the discussion and execution of interdisciplinary TDII research.
Broadly, the identified issues fell into 4 of the 6 categories of the Stokols et al.’s [Reference Stokols11] framework: intrapersonal, interpersonal, organizational, and physical environment. Subdomains were identified for each of these factors, including leadership, power and organizational hierarchy, accountability and responsibility, taxonomy and language, and exposure and isolation. Responding to iterative questioning, the group also provided a very thoughtful list of management practices, problems, and solutions for each of the 6 categories of the SciTS framework (see Table 2).
DII, dissemination, implementation, and improvement.
Intrapersonal
Accountability and Responsibility
The panel participants emphasized the importance of development and recognition of boundaries and responsibilities regarding the processes of interdisciplinary TDII research. In collaborations, research team members are assigned to different tasks because it can be beneficial to build on the existing expertise of individual members to meet shared goals. It may become a challenge if team members face time constraints, role confusion, limited motivation, and other contextual pressures. These issues illustrate the need for solutions that help define ownership (accountability) and commitment (responsibility) and are focused on both individual and group needs and priorities. The literature on setting goals and teamwork may provide guidance in working with diverse team members and identifying overarching, beneficial, and common goals when engaging in interdisciplinary TDII research [Reference Green and Kreuter13, Reference Tabak14]. This work design requires structure and clarity, so each member knows his or her role in accomplishing the overarching goal without overstepping boundaries or neglecting to engage in individual activities, fostering collaboration among groups, and promoting the health of the community.
Interpersonal
Leadership
We identified multiple issues and challenges related to leadership and facilitating or constraining interdisciplinary TDII research. Participants reported an example in which institutional leaders created synergies across 2 professional schools (social work and engineering) by convening scientists and providing a vision, resources, and support for collaboration across a university setting. A second example took place at Kaiser Permanente, where the leader of a department implemented a process for collaboration across specialists and allied health professionals to manage patients with heart failure. Overall, these examples and participant reports suggest that to engage relevant leaders in interdisciplinary TDII research, it is necessary to foster leadership commitment to interdisciplinary work by exposing leaders to models and teams from different disciplines and identifying visionary supportive leaders to act as local champions.
Leadership engagement and buy-in has been shown to be critical to success in organizational change, quality improvement, and effective implementation in health and social services [Reference Tabak14–Reference Guerrero and Kim16]. Interdisciplinary TDII research involves leadership from multiple disciplines, potentially increasing the complexity of and need for engagement and buy-in [Reference Brownson, Colditz and Proctor3]. Identifying appropriate supportive leadership across disciplines and achieving high-level agreement on goals and objectives may be a complex and lengthy process. In addition, different levels of leadership may be required to move interdisciplinary health sciences TDII research forward. For example, research in a health system setting may require regional and local leadership involvement, such as an area medical chief and a service line leader (eg, oncology, cardiology), and may need to represent both clinical and operational leaders. Leadership style may also vary across these levels and disciplines, but the common thread is leaders’ vision of how interdisciplinary work will improve TDII research.
Organizational
Exposure to Other Disciplines
Another important issue identified was the challenge of finding and connecting with partners and stakeholders in other disciplines. Participants suggested investing in and developing interdisciplinary team training early in graduate education. For example, some medical and nursing schools have successfully implemented programs for students to learn about patient care and health-care delivery in a team-based context. The expectation is that exposure during formative training will help reshape conceptualized roles, influence the likelihood of future interdisciplinary interactions, and normalize those interactions.
Scientists tend to focus on journals, conferences, and training that align with single-discipline silos, with limited opportunities for engagement in activities that cross silos. There may also be a limited number of role models who employ a multidisciplinary approach and model successful expansion beyond disciplinary silos and specialty boundaries. The main challenge is to find leaders in other disciplines who can expand the perspectives of potential collaborators.
Power and Hierarchy
Closely related to leadership are issues of power and organizational hierarchy related to engaging in interdisciplinary TDII activities. To decrease power differentials based on discipline status or other ideologies, participants suggested including leadership interventions to promote teamwork, active discouragement of use of status, and collaboration efforts across disciplines and within organizations to encourage effective interaction and communication among members. Specifically, interdisciplinary TDII research needs to focus on the different levels of institutions, policies, leaders, teams, and individuals that influence collaboration.
Demonstrating appreciation for and the value of team members with different training, experience, and expectations regarding research evidence, statistical analyses, and theoretical and conceptual methods is critical to the success of interdisciplinary TDII research. However, power hierarchies may play a role in how members from different disciplines (eg, medicine and social work) interact and engage when working toward a common goal. The organizational literature has relied on leadership and managerial interventions that seek to alter the norms and values of organizational culture to reduce conflict among team members [Reference Collins and Holton17–Reference Jayne and Dipboye19]. The effectiveness of these interventions is enhanced through experience and competence at individual, group, and organizational levels [Reference Collins and Holton17]. Knowledge and experience that is highly valued in one discipline may not be as valued, or even regarded unfavorably, in another. Achieving equal voice on the team, and concurrent perceptions of safety when interacting across disciplines, is a necessary component of effective interdisciplinary TDII research [Reference Tabak14].
Physical Environment
Structure and Isolation
Another important theme of this discussion involved silos—specifically, the tendency of single disciplines to create structural and ideological silos. Participants agreed that this is a significant barrier to collaboration. To promote communication across disciplines, they said it is important to invest in and develop robust data infrastructures to facilitate collaboration. Examples of such efforts include the Health Maintenance Organization (HMO) Research Network’s Virtual Data Warehouse and the University of California Research Data Exchange. Having common data standards facilitates multisite interdisciplinary research and provides a common language for clinicians and researchers from diverse backgrounds to easily communicate and engage in research.
Formally discussing differing incentives and developing a structured approach to aligning incentives across disciplines are crucial steps in developing interdisciplinary partnerships. The importance of factors such as publications, revenue streams, quality metrics, memoranda of understanding, and tenure must be explicitly discussed during the formation of interdisciplinary TDII teams and creation of specific incentives for collaboration in partnership agreements. These recommendations are a first step toward reducing structural and ideological silos and have the potential to influence the amount, content, and impact of interdisciplinary translational TDII research.
Communication, Taxonomy, and Language
Another challenge to promoting interdisciplinary TDII research is the structural content of communication across disciplines. Scientists from different disciplines may refer to the same phenomena with different terms. To respond to these issues, the group suggested the use of interdisciplinary language to develop consolidated frameworks for a variety of TDII research areas. This approach can draw from the development of the consolidated framework for implementation research led by researchers at the US Department of Veterans Affairs [Reference Damschroder20], which organized meetings with researchers at different departments and staff members at different levels to consolidate information under a unifying framework. To pursue approaches such as concept mapping (ie, a graphic organizer for representing concepts), participants recommended exploring National Institutes of Health resources on building interdisciplinary teams and relying on information science to allow rapid, reproducible mapping of concepts and definitions, and continuous consolidation of related concepts.
Discussion
Interdisciplinary TDII research is important to enhance the use of EBPs across multiple disciplines and is a critical part of knowledge translation. The exploration and use of the SciTS collaboration framework provides a useful context to invest in understanding and addressing contextual factors that promote multidisciplinary work in TDII research. The findings fall broadly into 4 of the 6 domains of the Stokols et al.’s [Reference Stokols11] framework: intrapersonal, interpersonal, organizational, and physical environment. Although not directly addressed, participants recommended approaches that incorporated the technological, social, and political domains. In particular, participants implicitly alluded to these domains when describing ways to enhance communication, methods, and interpersonal relationships among scientists. The topics and urgency in panel reports were consistent with the extant literature in terms of the importance of relationships, leadership, power, physical environment, and the use of technology to improve interdisciplinary collaboration.
Findings from this exploratory study should be interpreted with caution. This was a preliminary descriptive study that relied on a small nonprobability sample of experts in TDII research who volunteered to participate; hence, findings have limited generalizability. However, this is an appropriate first step to identify relevant concepts, scenarios, and related solutions to enhance transdisciplinary collaborations in TDII research and practice.
These preliminary findings have significant implications for TDII practice. Changes in policy and practice should focus on the role of leadership, power, and organizational hierarchy with the goal of fostering commitment and developing a vision to support leadership and incentives in administering joint projects in TDII research. Please refer to Table 2 for examples. Another component to consider is the significance of universities or organizations in developing credibility, building accountability and responsibility, and focusing efforts on improving communication strategies. Future work should examine domains, problems, and solutions to improve process and proximate outcomes, such as communication, coordination, collaboration, and problem solving among researchers from different backgrounds conducting TDII research.
