Summary

The goal of this clinical trial is to learn if a multilevel blended educational intervention based on Social Cognitive Theory (SCT) can increase fruit and vegetable (F\&V) consumption among female students.

The main questions it aims to answer are:

* Does an SCT-based educational program increase the daily amount of fruit and vegetable intake among adolescent girls?
* Does the intervention improve key cognitive-social constructs such as self-efficacy, self-regulation, knowledge, behavioral skills, and social support related to healthy eating? Researchers will compare students in the intervention group who receive seven 60-minute blended sessions (including face-to-face and WhatsApp-based education) tailored according to SCT constructs to a control group receiving no intervention.

Participants will:

* Attend scheduled educational sessions covering nutrition knowledge, skill-building (e.g., meal preparation with F\&V), and behavior change strategies.
* Participate in activities designed to enhance self-efficacy, observational learning, and social support for healthy eating.
* Complete validated questionnaires assessing F\&V intake and SCT-related cognitive-social constructs before and two months after the intervention.

This study evaluates whether integrating theory-driven, multilevel interventions in schools is effective in promoting healthier dietary habits among adolescent girls, especially in a resource-constrained setting.

Multicomponent Social Cognitive Theory-Based Educational Program to Increase Fruit and Vegetable consumption in Students

This multilevel blended educational intervention applies Social Cognitive Theory (SCT) to increase fruit/vegetable (F/V) intake among female middle school students. The 8-week program includes: A) Student Components: * Seven 60-minute sessions (4 in-person, 3 WhatsApp-delivered) * Interactive activities: cooking demonstrations, goal-setting workshops, and educational games * SCT-focused content: self-efficacy building, outcome expectation modification B) Parental Engagement: * Weekly SMS nutrition tips * Two virtual workshops on creating F/V-supportive home environments * School Environment Modifications: * Cafeteria redesign to promote F/V accessibility * Peer-led 'Healthy Eating Ambassador' program Unique aspects distinguishing this intervention: * First SCT-based program specifically adapted for Iranian adolescent females * Dual delivery (in-person + digital) optimized for school settings * Simultaneously targets individual, social, and environmental determinants.
