Determination of Sustainable Consumption Behaviors of Pre-service Science Teachers Using the Theory of Planned Behavior: A Case of Fast-Food

Abstract

Individuals’ sustainable consumption has a substantial effect on the environment. In particular, fast-food consumption is an important obstacle to a sustainable life. Therefore, understanding antecedents of fast-food consumption behavior helps to develop sustainable education interventions. The study aims to examine factors affecting fast food consumption behaviors within the framework of the sustainability framework using the theory of planned behavior. The sample data of 270 participants were from pre-service science teachers. The data of the study were collected several scales. A belief scale was developed by researchers. Other scales were adapted from the previous studies. The analysis was performed using hierarchical multiple regression analysis. The results revealed that the conceptual model explained 19 % of the variance in intention and 33 % of the variance in behavior. Besides, the proposed relationships among the constructs within the model were broadly supported. Further, intention was found to be a significant mediating variable. Finally, the study provides important theoretical and practical implications as well as suggestions for future researchers.

Fen Bilgisi Öğretmen Adaylarının Sürdürülebilir Tüketim Davranışlarının Planlanmış Davranış Teorisi Kullanılarak Belirlenmesi: Bir Fast-Food Örneği

Öz

Bireylerin tüketim davranışlarının çevre üzerinde önemli bir etkisi vardır. Özellikle fast food tüketimi sürdürülebilir bir yaşamın önünde önemli bir engel olarak yer almaktadır. Bu nedenle, fast food tüketim davranışının öncüllerini anlamak, sürdürülebilir kalkınma sürecinde eğitimsel uygulamalarının geliştirilmesine yardımcı olabilecektir. Bu çalışma, planlanmış davranış teorisini kullanarak fast food tüketim davranışlarını etkileyen faktörleri sürdürülebilirlik çerçevesi çerçevesinde incelemeyi amaçlamaktadır. Bu doğrultuda kavramsal bir model önerilmiştir. Araştırmaya 270 fen bilgisi öğretmen adayı katılmıştır. Araştırmanın verileri araştırmacılar tarafından geliştirilen inanç ölçeği ve literatürden elde edilen ölçekler yardımıyla toplanmıştır. Verilerin analizi hiyerarşik çoklu regresyon analizi yardımıyla yapılmıştır. Araştırmadan elde edilen sonuçlar incelendiğinde kavramsal modelin fast food tüketim niyeti üzerindeki varyansın %19'unu ve davranıştaki varyansın %33'ünü açıkladığını ortaya koymuştır. Ayrıca, model içindeki yapılar arasında önerilen ilişkiler geniş çapta desteklenmiştir. Ayrıca niyetin önemli bir aracı değişken olduğu bulunmuştur. Son olarak, çalışma önemli teorik ve pratik çıkarımların yanı sıra gelecekteki araştırmacılar için öneriler sunmaktadır.
