: a comparative analysis between Portugal and Colombia

  • Susana Gómez Martínez (Student)

Student thesis: Master's Thesis


Given the current gap and lack of literature understanding the relationship between a consumer purchase behavior focusing on environment (sustainable packaging) and a consumer purchase behavior focusing on health (organic food), both having important impacts on current socio-economic trends and the ecosystem, this dissertation´s objective is to determine the relevance of packaging sustainability for organic food consumers in retail. Taking into consideration that the investigation was seeking to explain a relationship between two variables, a quantitative method through a survey strategy was chosen, selecting a questionnaire as the collection method. Then, the investigation premises were tested through Structural Equation Modeling, performing a factor Confirmatory Factor Analysis, followed by the assessment of the final structural model. After a thoughtful analysis performed on the collected data, it was possible to demonstrate that packaging sustainability satisfaction substantially impacts Attitude and Perceived Behavioral Control, variables of the consumer purchasing organic food, following the Reasoned Action Approach (RAA) model. Finally, a comparative analysis was performed between Portugal and Colombia with no major differences encountered among the two countries’ perceptions on packaging sustainability for organic food.
