The Effect of a Social Cognitive Theory-Based Educational Intervention Program on Sustainable Eco-Friendly Nutrition, Nutritional Attitudes, and Self-Efficacy in Adolescents: A Randomized Controlled Trial
Abstract
This study is designed as a parallel-group randomized controlled trial to evaluate the effectiveness of a sustainable environmentally friendly nutrition educational intervention program developed based on the principles of Social Cognitive Theory. The intervention aims to improve sustainable environmentally friendly nutrition behaviors, nutritional attitudes, and nutrition self-efficacy among adolescents.
Eligible participants will be randomly assigned to either an intervention group or a control group using a computerized simple randomization procedure conducted by an independent researcher. Allocation concealment will be ensured through participant coding, and data analysis will be performed by an independent biostatistician blinded to group assignments.
The intervention group will participate in a structured six-week educational program, consisting of one session per week. Each session will last approximately 40 minutes and will focus on a specific module addressing the relationship between climate change, environmental sustainability, and nutrition. Program content is grounded in Social Cognitive Theory, emphasizing observational learning, self-regulation, outcome expectations, and self-efficacy enhancement. Educational methods will include interactive presentations, group discussions, games, and activity-based learning supported by visual and audio materials to promote engagement and long-term behavioral change.
