Abstract: Background: Social Capital on health has been studied widely, to date there is no valid and reliable questionnaire that measure it in Chronic Kidney Disease (CKD). Objective: To develop, validate and assess the reliability of Social Capital related to CKD questionnaire for Mexican adolescents. Methods: An instrumental study was employed to validate a questionnaire that assesses the cognitive and structural domains of Social Capital related to CKD. The questionnaire was generated by operationalization of the constructs and validated by assessing the content, face validity, criteria and construct validity. Reliability was assessed through the Cronbach´s alpha. Results: The content validity of the questionnaire was confirmed through Kendall’s W of 0.925 (p = 0.01) and its face validity was evaluated by four focus groups. A principal component analysis on a sample of 281 adolescents indicated that 72.78% of the variance was explained by the cognitive domain and 83.20% by the structural domain. A confirmatory analysis returned a chi-squared value of 142.99 (p = 0.05), a CFI of 0.97, a TLI of 0.96, a RMSEA of 0.040 and a SRMR of 0.07 for the cognitive domain. Similarly, a chi-squared of 408.296 (p
