Abstract: Background: Rasavaha Srotas is the principal channel for nutrient transport (Rasa Dhatu) in Ayurveda. Its vitiation (Srotodushti) manifests through a spectrum of symptoms described in classical texts, but a standardized, validated assessment tool is lacking. Aim: To develop and validate the Rasavaha Srotodushti Assessment Scale (RSAS) questionnaire. Methods: A cross-sectional study was conducted. The 13-item scale was derived from classical Ayurvedic literature and validated through face, content, and construct validation with ten experts. Internal consistency, item-total correlations, and factor analysis suitability were assessed in 108 participants. Severity was categorized using arbitrary cutoffs: Mild (13-30), Moderate (31-48), and Severe (49-65). Results: The scale demonstrated excellent internal consistency (Cronbach's ? = 0.916). Content validity was high (S-CVI/Ave = 0.93). The Kaiser-Meyer-Olkin measure was 0.862, and Bartlett's test was significant (p < 0.001), confirming factorability. Severity distribution was: Mild 73.1%, Moderate 23.1%, and Severe 3.7%. Conclusion: The RSAS is a valid, reliable, and clinically applicable tool for assessing Rasavaha Srotodushti, suitable for use in screening, diagnosis, and therapeutic monitoring in Ayurvedic practice and research
