Beginning With the End in Mind: Contextual Considerations for Scaling-Out a Community-Based Intervention

Introduction: A number of effective physical activity programs for older adults exist, but are not widely delivered within community settings, such as the Cooperative Extension System. The purpose of this paper was to determine if an evidence-based intervention (EBI) developed in one state Extension system could be scaled-out to a new state system. Methods and results: The RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework was used to guide an iterative evaluation of three translational stages. Stage 1: Before program adoption, Extension health educators were surveyed and interviewed to assess physical activity programming perceptions and factors that may influence their decision to attend training or deliver the program in practice. Results indicated that a virtual, scalable training protocol would be necessary and that training needed to include hands-on instruction and be catered to those who were less confident in physical activity program delivery. Stage 2: Training attendees were surveyed pre- and post-training on factors related to the adoption-decision making process and contacted post-training to assess program delivery status. Training did not influence perceptions of the program, intent to deliver, or confidence in delivering the program. Stage 3: During program implementation, the program was evaluated through the RE-AIM framework by surveying across three key stakeholder groups: (1) program participants, (2) potential delivery personnel, and (3) Extension administrators. Findings indicate that the program has the potential to reach a large and representative proportion of the target audience, especially in rural areas. However, adoption and implementation rates among Extension health educators and community partners were low and data collection for effectiveness, implementation, and maintenance was a challenge. Conclusion: Overall, the results indicate initial struggles to translating and evaluating the program in a large, rural state. Implications for practice include making system-level changes to increase physical activity program adoption rates among Extension health educators and improve data collection and program evaluation through this community-based organization. More work is needed to identify infrastructure support and capacity to scale-out EBIs.

Evaluation of a Behavioral Intervention With Multiple Components Among Low-Income and Uninsured Adults With Obesity and Diabetes

Purpose:

To examine the effects of a community-based behavioral intervention with multiple components on health outcomes among low-income and uninsured adults who were obese and had diabetes and treated in a “real-world” setting.

Design:

A longitudinal design with a retrospective comparison group was used to examine the ability of a health promotion program to improve body mass index (BMI) and hemoglobin A1c (HbA1c) among 87 treatment group and 62 comparison group participants.

Setting:

Urban/metropolitan city in the United States.

Intervention:

A community-based behavioral intervention with 3 components including health-coach visits, registered dietitian visits, and exercise consultations delivered over 12 months.

Measures:

Biometric measurements were collected at baseline, 3, 6, 9, 12, and 18 months, whereas self-reported measurements were collected at baseline, 6 months, and 12 months.

Analysis:

Linear mixed models with participant-level random intercepts were fitted for BMI and HbA1c.

Results:

The treatment group demonstrated reductions in BMI (percentage change = −2.1%, P < .001) and HbA1c (−0.6%, P < .001) as well as improvement in diabetes knowledge (+5.4%, P = .025), whereas the comparison group did not show any improvements in biometric measures. Dietitian visits were the most effective treatment component to reduce HbA1c (coefficient = −0.08, P = .025).

Conclusion:

Multiple component behavioral intervention in community settings, particularly when delivered by registered dietitians, shows promise to combat the dual epidemic of obesity and diabetes among low-income and uninsured patients.
