Creating logic models using grounded theory: a case example demonstrating a unique approach to logic model development


This article describes, using a case example, the procedure of creating logic models using grounded theory methodology in the context of process evaluation. There currently exists a dearth of literature on the specifics of how logic models should be created. The authors reduce this gap by detailing an integrated methodology they utilized during their recent evaluation of the Youth Educating About Health (YEAH) program. A number of parallels between grounded theory and logic modelling are first discussed to demonstrate their potential for integration. Then the data collection and analysis procedures are explained with a focus on how the integration between grounded theory and logic modelling was conducted. The completed logic model is then presented and each category is explained in detail. The authors conclude by discussing the lessons they learned from utilizing this integrated methodology. These lessons include the specific benefits this methodology contributes to process evaluation, the added depth of information that grounded theory provides to logic modelling, and the cost- and time-effectiveness of this unique methodology.
