Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
To reinforce learning and facilitate behavior maintenance, supplementary reinforcement messages will be delivered throughout the intervention period. Communication with participants and their parents will be maintained via digital messaging platforms to support adherence and engagement.
The control group will continue their routine school curriculum without receiving any nutrition-related educational intervention during the study period.
Outcome data will be collected at four time points: baseline (pre-intervention), immediately after completion of the six-week program (post-intervention), and at one-month and three-month follow-up assessments. Data collection is expected to take approximately 25 minutes at each assessment point. The follow-up assessments are intended to evaluate the sustainability of behavior change over time.
The intervention will be implemented during the fall semester of the 2025-2026 academic year following the completion of ethical approval and institutional permissions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention Group
Following pretests, participants will be randomly assigned to intervention and participation groups. The intervention group will receive a total of six weeks (six sessions) of the intervention program. Each session is planned to last approximately one class hour (40 minutes). Each session will begin with presentations based on literature, followed by various activities and games to reinforce the topic and support lasting behavioral changes in students. The games were designed according to the gamification model.
Social Cognitive Theory-Based Educational Intervention Program
In this study, a sustainable eco-friendly nutrition educational intervention program was developed based on social cognitive theory. The sustainable eco-friendly nutrition educational intervention program will last six weeks. Each session will consist of one session per week, covering one module. Each session is expected to last approximately 40 minutes. Each module will utilize presentations based on the content, followed by various activities and games to reinforce the topic and support lasting behavioral changes in students.
To reinforce the knowledge and practices adolescents have learned and implemented during the program, and to strengthen the impact of the intervention, the researcher will prepare 12 SMS (Short Message Service) messages using various sources and send them individually to adolescents/parents.
Control Group
The control group will not receive any intervention and will continue their education in accordance with the current curriculum. Data collection tools will be administered again one and three months after the pretest, posttest, and interventions are completed in parallel with the intervention group. The intervention may be administered after the program is completed, at the request of the school administration.
