• 1 other identifier: ErciyesU-DYT-OM-01
• Study Type: interventional
• Target: 70

Brief Summary

The aim of this intervention study is to evaluate the effect of sustainable nutrition education based on the Transtheoretical Model (TTM) on adolescent behavior. The main questions to be answered are:

• Do adolescents have sufficient knowledge about sustainable nutrition?
• Can a sustainable nutrition education based on TTM lead to positive changes in the sustainable eating habits of adolescents? Researchers will compare the study group that received the education with the control group that did not receive the education to determine the effect of TTM based nutrition education on dietary behavior. Participants will:
• Receive education relevant to the behavior change phase.
• Receive a maximum of two training sessions per week, and the training will last 5 weeks.

Outcome Measures

Primary Outcomes (2)

• Change in Transtheoretical Model Based Sustainable Nutrition Behaviour Scales

  The scale consists of 44 items. It is a 5-point Likert type scale. Evaluation is made on a scale from 1 to 5, from never to always.As scores increase, behavioral changes towards sustainable and healthy eating, decision-making, and self-efficacy develop in a positive direction.

• Change in Transtheoretical Model Based Sustainable Nutrition Behavior Change Stage Question

  Participants will be given a definition of sustainable and healthy nutrition, and they will be asked to evaluate their sustainable and healthy nutrition behaviors according to the definition and to mark which stage they are in according to the TTM change stage. Stage of behaviour determined according to the options offered in accordance with the definition: Pre-contemplation Stage : (☐) I do not currently eat according to the definition and do not plan to change my diet in the next 6 months. Contemplation Stage : ( ☐ ) I do not currently eat according to the definition, but plan to change my diet in the next 6 months. Preparation Stage : ( ☐ ) I do not currently eat according to the definition, but I plan to eat healthier and consider the environmental impact in the next 30 days. Action Stage : ( ☐ ) I have been on a sustainable eating plan for 6 months now. Maintenance Stage : ( ☐ ) I have been on a sustainable eating plan for over 6 months.

Study Arms (2)

Intervention Group (educated about sustainable nutrition)

EXPERIMENTAL

The research will be conducted in an Anatolian high school. The experimental group will be randomly selected from the students who meet the inclusion criteria and are willing to participate in the study. The experimental group will receive sustainable nutrition education programme based on the transtheoretical model. The training content will be applied face-to-face at most twice a week for five weeks.

Behavioral: Sustainable nutrition education based on the transtheoretical model

Control Group ( non-educated about sustainable nutrition)

NO INTERVENTION

In order to prevent any potential influence from peer interaction, the control group will be composed of students from another Anatolian high school with a similar socio-economic and educational background. The control group will be randomly selected from students who meet the inclusion criteria and are willing to participate in the study. The sustainable nutrition education programme will not be applied to this group.

Interventions

Sustainable nutrition education based on the transtheoretical model BEHAVIORAL

Before the intervention begins, the Sustainable Nutrition Behaviour Change Stage Survey will be administered to determine participants' training stage. In addition, the Transtheoretical Model (TTM) Based Sustainable Nutrition Scales will be administered to evaluate the effectiveness of the training programme. TTM Based Nutrition Training Programme consists of 11 modules developed according to the stages of the model.The methodology and tools used are aligned with the objectives of the training programme.The training modules are offered twice a week, with each session lasting a maximum of 40 minutes and continues for a total of 5 weeks. Participants may attend more than one training session in order to develop behaviours that increase adherence to a sustainable diet. At the end of the training programme, data from the Transtheoretical Model-Based Sustainable Nutrition Behaviour Scale will be collected again and evaluated by comparison with the baseline data set..
