Determinants of organic food purchases intention: the application of an extended theory of planned behaviour
organic food purchases intention
Abstract
This investigated the application of the extended theory of planned behavior (TPB) to determine Iranian students’ intention to purchase organic food products. The statistical population comprised all students in the field of agriculture sciences at Mohaghegh Ardabili University, Ardabil, Iran. Data were collected from 340 participants. The research instrument was a questionnaire developed through a comprehensive literature study. The content validity of the instrument was ascertained by a panel of university professors and its reliability by Cronbach’s alpha. Data were analyzed using SPSS v22 and LISREL8.80 software packages. The results of the structural equations model (SEM) showed that the variables of attitude, subjective norms, perceived behavioral control, moral norms, health consciousness, and environmental concern could account for 86 percent of the variance of students’ intention to purchase organic products. In addition, results revealed that environmental concern and health consciousness highly influenced (41 percent) attitude towards organic food products. Based on the results recommendations are made.
