Identification of Intervention Characteristics Within Diabetes Prevention Programs Using the Template for Intervention Description and Replication: A Scoping Review

OBJECTIVES

Diabetes prevention programs (DPPs) targeting dietary and physical activity behaviour change have been shown to decrease the incidence of type 2 diabetes; however, a more thorough reporting of intervention characteristics is needed to expedite the translation of such programs into different communities. In this scoping review we aim to synthesize how DPPs are being reported and implemented.

METHODS

A scoping review using Arkey and O'Malley methods was conducted in accordance with the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis. MEDLINE, CINAHL, PsycINFO, EMBASE, and SPORTDiscus were searched for studies relating to diabetes prevention, and diet/exercise interventions. Only studies delivering a diet/exercise intervention for adults identified as "at risk" for developing type 2 diabetes were included. The Template for Intervention Description and Replication (TIDieR) was used to guide data extraction, and each DPP was scored on a scale from 0 to 2 for how thoroughly it reported each of the items (0 = did not report, 2 = reported in full; total score out of 26).

RESULTS

Of the 25,110 publications screened, 351 (based on 220 programs) met the inclusion criteria and were included for data extraction. No studies comprehensively reported on all TIDieR domains (mean TIDieR score: 15.7 of 26; range 7 to 25). Reporting was particularly poor among domains related to "modifications," "tailoring," and "how well (planned/actual)." "How well (planned)" assesses the intended delivery of an intervention, detailing the initial strategies and components as per the original design, whereas "how well (actual)" evaluates the extent to which the intervention was executed as planned during the study, including any deviations or modifications made in practice.

CONCLUSIONS

Although there is evidence to suggest that DPPs are efficacious, a more thorough reporting of program content and delivery is needed to improve the ability for effective programs to be implemented or translated into different communities.

Designing and Developing Online Training for Diabetes Prevention Program Coaches Using an Integrated Knowledge Translation Approach: Development and Usability Study

BACKGROUND

e-Learning has rapidly become a popular alternative to in-person learning due to its flexibility, convenience, and wide reach. Using a systematic and partnered process to transfer in-person training to an e-learning platform helps to ensure the training will be effective and acceptable to learners.

OBJECTIVE

This study aimed to develop an e-learning platform for Small Steps for Big Changes (SSBC) type 2 diabetes prevention program coaches to improve the viability of coach training.

METHODS

An integrated knowledge translation approach was used in the first 3 stages of the technology-enhanced learning (TEL) evaluation framework to address the study objective. This included three steps: (1) conducting a needs analysis based on focus groups with previously trained SSBC coaches, meetings with the SSBC research team, and a review of research results on the effectiveness of the previous in-person version of the training; (2) documenting processes and decisions in the design and development of the e-learning training platform; and (3) performing usability testing. Previously trained SSBC coaches and the SSBC research team were included in all stages of this study.

RESULTS

Step 1 identified components from the in-person training that should be maintained in the e-learning training (ie, a focus on motivational interviewing), additional components to be added to the e-learning training (ie, how to deliver culturally safe and inclusive care), and mode of delivery (videos and opportunities to synchronously practice skills). Step 2 documented the processes and decisions made in the design and development of the e-learning training, including the resources (ie, time and finances) used, the content of the training modules, and how coaches would flow through the training process. The design and development process consisted of creating a blueprint of the training. The training included 7 e-learning modules, the learning modalities of which included narrated demonstration videos and user-engaging activities, a mock session with feedback from the research team, and a final knowledge test. Step 3, usability testing, demonstrated high levels of learnability, efficiency, memorability, and satisfaction, with minor bugs documented and resolved.

CONCLUSIONS

Using an integrated knowledge translation approach to the technology-enhanced learning evaluation framework was successful in developing an e-learning training platform for SSBC coaches. Incorporating end users in this process can increase the chances that the e-learning training platform is usable, engaging, and acceptable. Future research will include examining the satisfaction of coaches using the SSBC coach e-learning training platform, assessing coach learning outcomes (ie, knowledge and behavior), and estimating the cost and viability of implementing this training.

Small Steps Towards an Inclusive Diabetes Prevention Program: How Small Steps for Big Changes is Improving Program Equity and Inclusion

Social determinants of health, the effects of colonialism, and systemic injustices result in some groups being at disproportionately higher risk for developing type 2 diabetes (T2D). Many T2D prevention programs have not been designed to provide equitable and inclusive care to everyone. This paper presents an example of the steps taken in an evidence-based community T2D prevention program, Small Steps for Big Changes (SSBC), to improve equitable access and inclusivity based on input from a stakeholder advisory group and the ConNECT Framework. To improve reach to those most at risk for T2D, SSBC has changed both eligibility criteria and program delivery. To ensure that all testing is done in an inclusive manner, changes have been made to measurements, and to training for those delivering the program. This paper also provides actionable recommendations for other researchers to incorporate into their own health programs to promote inclusivity and ensure that they reach those most at risk of T2D.

Examining the Effectiveness of an E-Learning Training Course for Coaches of a Type 2 Diabetes Prevention Program

Small Steps for Big Changes (SSBC) is a community-based diabetes prevention program (DPP). SSBC utilizes a motivational interviewing (MI) informed counseling style to deliver a structured diet and exercise curriculum to empower healthy behavioral modifications and prevent type 2 diabetes (T2D). An electronic learning (e-learning) platform to train SSBC coaches was developed to improve flexibility, reach, and accessibility. While e-learning has shown to be an effective mode of teaching content to health professionals, less is known in the context of DPP coaches. This study aimed to assess the effectiveness of the SSBC e-learning course. Twenty coaches (eleven fitness staff personnel and nine university students) were recruited through existing fitness facilities to participate in the online SSBC coach training which included completing pre- and post-training questionnaires, seven online modules of content and a mock client session. Knowledge regarding MI (Mpre = 3.30 ± 1.95, Mpost = 5.90 ± 1.29; p < 0.01), SSBC content (Mpre = 5.15 ± 2.23, Mpost = 8.60 ± 0.94; p < 0.01), and T2D (Mpre = 6.95 ± 1.57, Mpost = 8.25 ± 0.72; p < 0.01), and self-efficacy to deliver the program (Mpre = 7.93 ± 1.51, Mpost = 9.01 ± 1.00; p < 0.01) all significantly increased from pre- to post e-learning training. Participants reported positively on the user satisfaction and feedback questionnaire with a mean score of 4.58/5 (SD = 0.36). These findings suggest e-learning platforms are a promising mode to improve DPP coaches' knowledge, counseling skills, and to bolster confidence in program delivery with high levels of satisfaction. E-learning to train DPP coaches allows for effective and feasible expansion of DPP's, ultimately permitting more reach to adults living with prediabetes.

Fitness Facility Staff Can Be Trained to Deliver a Motivational Interviewing-Informed Diabetes Prevention Program

Background: Training programs must be evaluated to understand whether the training was successful at enabling staff to implement a program with fidelity. This is especially important when the training has been translated to a new context. The aim of this community case study was to evaluate the effectiveness of the in-person Small Steps for Big Changes training for fitness facility staff using the 4-level Kirkpatrick training evaluation model. Methods: Eight staff were trained to deliver the motivational interviewing-informed Small Steps for Big Changes program for individuals at risk of developing type 2 diabetes. Between August 2019 and March 2020, 32 clients enrolled in the program and were allocated to one of the eight staff. The Kirkpatrick 4-level training evaluation model was used to guide this research. Level one assessed staff satisfaction to the training on a 5-point scale. Level two assessed staff program knowledge and motivational interviewing knowledge/skills. Level three assessed staff behaviors by examining their use of motivational interviewing with each client. Level four assessed training outcomes using clients' perceived satisfaction with their staff and basic psychological needs support both on 7-point scales. Results: Staff were satisfied with the training (M = 4.43; SD = 0.45; range = 3.86-4.71). All learning measures demonstrated high post-training scores that were retained at implementation follow-up. Staff used motivational interviewing skills in practice and delivered the program at a client-centered level (≥6; M = 6.34; SD = 0.83; range = 3.75-7.80). Overall, clients perceived staff supported their basic psychological needs (M = 6.55; SD = 0.64; range = 6.17-6.72) and reported high staff satisfaction scores (M = 6.88; SD = 0.33; range = 6-7). Conclusion: The Small Steps for Big Changes training was successful and fitness facility staff delivered a motivational interviewing-informed program. While not all staff operated at a client-centered level, clients perceived their basic psychological needs to be supported. Findings support the training for future scale-up sites. Community fitness staff represent a feasible resource through which to run evidence-based counseling programs.

Using the behavior change wheel to develop text messages to promote diet and physical activity adherence following a diabetes prevention program

Improving diet and physical activity (PA) can reduce the risk of developing type 2 diabetes (T2D); however, long-term diet and PA adherence is poor. To impact population-level T2D risk, scalable interventions facilitating behavior change adherence are needed. Text messaging interventions supplementing behavior change interventions can positively influence health behaviors including diet and PA. The Behavior Change Wheel (BCW) provides structure to intervention design and has been used extensively in health behavior change interventions. Describe the development process of a bank of text messages targeting dietary and PA adherence following a diabetes prevention program using the BCW. The BCW was used to select the target behavior, barriers and facilitators to engaging in the behavior, and associated behavior change techniques (BCTs). Messages were written to map onto BCTs and were subsequently coded for BCT fidelity. The target behaviors were adherence to diet and PA recommendations. A total of 16 barriers/facilitators and 28 BCTs were selected for inclusion in the messages. One hundred and twenty-four messages were written based on selected BCTs. Following the fidelity check a total of 43 unique BCTs were present in the final bank of messages. This study demonstrates the application of the BCW to guide the development of a bank of text messages for individuals with prediabetes. Results underscore the potential utility of having independent coders for an unbiased expert evaluation of what active components are in use. Future research is needed to demonstrate the feasibility and effectiveness of resulting bank of messages.
