Implementing Group Model Building With the Shape Up Under 5 Community Committee Working to Prevent Early Childhood Obesity in Somerville, Massachusetts

Abstract

Objective: To describe our process of using group model building (GMB) with the Shape Up Under 5 Committee; measure the effects on Committee members; and describe the community-wide health messaging campaign that resulted from the process. Design: Pilot study. Setting: Somerville, Massachusetts. Participants: Members of the Shape Up Under 5 Committee, a multisector group of professionals. Intervention: Research team convened the Committee and facilitated GMB from October 2015 to June 2017. Main Outcome Measures: Boundary objects produced during GMB activities; committee members' perspectives on early childhood obesity in their community; and Committee members' knowledge, engagement, and trust at the conclusion of each meeting. Results: Working together using GMB activities and with support from the research team, the Committee created a community-wide campaign that provided evidence-based messages to reach an entire city that emphasized diversity and reaching immigrants and community members who spoke languages other than English. More than 80% of Committee members reported changes in their perspectives related to early childhood obesity at the conclusion of the pilot test. Six perspective shift themes emerged from interviews and open-ended survey items: exposure to new perspectives about challenges community members face; increased awareness of others working on similar issues; increased knowledge about early childhood obesity; seeing value in creating a space to work across sectors; appreciating complexity and linkages between early childhood obesity prevention and other community issues; and how participation in committee influences members' priorities in their own work. Knowledge of and engagement with early childhood obesity prevention varied at the conclusion of each meeting, as did increases in trust among Committee members. Conclusion: Group model building is a promising approach to support multisector groups working to address early childhood obesity in their community. Meeting activities may have had differential impacts on members' knowledge of and engagement with early childhood obesity.

Tracing coalition changes in knowledge in and engagement with childhood obesity prevention to improve intervention implementation

“…The Catalyzing Communities project design and methods are described elsewhere [ 25 , 27 ]. In brief, Catalyzing Communities investigates the attributes and processes of newly formed coalitions (the “Coalition-Committee”) that are convened for the study and comprised of stakeholders from an array of sectors (e.g., community-based organizations, community members, hospitals, schools, philanthropy) serving children and their families.…”

“…It is based on the Stakeholder-Driven Community Diffusion Theory, which describes an empirically testable mechanism for promoting community change whereby knowledge of and engagement with childhood obesity within a group of convened stakeholders can diffuse through their social networks and lead to changes in policies, systems, and environments that have been shown impact children’s behaviors and health outcomes [ 28 , 29 ]. Our SDCD-informed intervention employs group model building and technical assistance with convened stakeholders to build knowledge, engagement, and the use of research evidence in community-led actions [ 27 ]. Our initial studies have been shown to increase knowledge of and engagement with childhood obesity prevention efforts among stakeholders [ 14 ].…”

An action‐oriented framework for systems‐based solutions aimed at childhood obesity prevention in US Latinx and Latin American populations

“…This underscores the critical need to engage a broad range of stakeholders relevant to the problem and mobilize their viewpoints and knowledge to achieve a better understanding of the system as a whole. Interviews with key informants and group model building activities are two ways of engaging with stakeholders, the latter enabling their active participation in the process of developing the systems map, leading not only to a more relevant model, but to a communal understanding of the system's form and function and shared vision and insights 2,9,14,37,39,40 …”

Implementing and Evaluating a Stakeholder-Driven Community Diffusion–Informed Early Childhood Intervention to Prevent Obesity, Cuyahoga County, Ohio, 2018–2020

“…Our research team used the SDCD theory to inform an intervention that targets specific constructs and processes. The intervention was pilot tested ( 21 ) and was then implemented in Cuyahoga County, Ohio; that implementation is the focus of this study.…”
