The present study aims to investigate the relationships between physical activity, body image, physical literacy, and perceived competence with anxiety in youth aged 18 to 39 residing in war zones. Despite previous research on the separate roles of these variables in mental health, an integrated model that explains their simultaneous interaction under the high-stress conditions of war has not been proposed. This descriptive-correlational study will be conducted online with 319 participants (based on G‑Power and a medium effect size). The instruments include the IPAQ, Fisher Body Image Questionnaire, Perceived Physical Literacy Instrument (PPLI), Harter Perceived Competence subscale, and Beck Anxiety Inventory, all of which have been validated in Iran. Data will be analyzed using Pearson correlation and multiple regression in SPSS. The hypothesis is that higher physical activity, more positive body image, higher physical literacy, and stronger perceived competence are associated with lower anxiety and have the power to predict it. This research fills the scientific gap in the field of motor behavior in wartime conditions and provides a basis for multifaceted interventions including promoting physical literacy, improving body image, and psychological empowerment. The findings have practical applications for psychologists, occupational therapists, health policymakers, and sports coaches.
