(P15-016-24) Development of the iNutritionCoachWV Telenutrition Intervention: An Intervention Mapping Approach

Objectives: There is a need to develop effective interventions to reduce diet-related chronic conditions that can be implemented across geographical locations. The development of effective interventions should target the needs of the population. This study aims to use intervention mapping to systematically design a theory-informed and evidence-driven telenutrition behavioral intervention to support patients at risk for cardiovascular disease in improving diet quality and weight status.

Methods: The IM protocol was systematically applied to develop the Theory-informed Nutrition Coaching for Adult Diet Change via Telehealth in West Virginia (THEiNutritionCoachWV) intervention. The steps included developing a logic model of the problem, outlining intervention outcome objectives, defining associated performance objectives, and mapping to targeted change objectives for five primary determinants of interest. The intervention was then designed using theory-based change methods with targeted applications and evidence-based nutrition care guidelines. Program materials relevant to the target audience of adults in rural WV and appropriate for the telehealth delivery model were developed.

Results: Based on the logic model of the problem, the personal determinants targeted in the study were identified as knowledge, self-efficacy, autonomy, competence, and relatedness. The determinants were formulated into matrices of change objectives and mapped in a logic model of change to guide the study design. THEiNutritionCoachWV intervention consists of virtual coaching sessions, a handbook and monthly newsletter that target the identified individual determinants of health. The behavior change techniques used in the intervention support motivation, behavioral capacity, knowledge and skill-building, self-monitoring, social support, restructuring environment and habit formation.

Conclusions: This research increases the transparency of intervention content and the identification of theoretical mechanisms of action targeted in the behavioral intervention. The process and resultant blueprint allow for replication and dissemination by future interventionists and researchers.
