Outcome Measure: Change in Perceived Importance of Health Habits (Baseline-Pre-Post)

A self-report questionnaire specifically developed for this study will be used to assess adolescents' perceived importance of maintaining healthy habits. The instrument consists of 16 Likert-type items (1 = Not important at all to 5 = Extremely important) that evaluate three domains: 1. Nutrition (e.g., balanced diet, regular meal patterns). 2. Hygiene (e.g., daily personal hygiene routines). 3. Physical exercise (e.g., regular engagement in physical activity). 4. Healthy sleep habits (e.g. sleeping at least 8 hours, having a defined schedule.) Higher scores indicate greater perceived importance attributed to healthy behaviors across the three domains, with a total score ranging from 16 to 80. Subscale scores will also be calculated for each domain. First measurement (T1): Baseline, after informed consent. Second measurement (T2): Approximately 4 weeks after baseline (pre-intervention re-assessment). Third measurement (T3): Approximately 4 weeks after T2 (post-intervention assessment)
