MARTINEZ-VAZQUEZ, Rosa Ivone; ALVARADO-RUIZ, Gerardo Alberto; SANCHEZ-PEREZ, Carmen  y  LEDO-RABAGO, Patricia Muñoz. Validity and reliability of the Neurobehavioral Evaluation of Infant Development (VANEDELA). Screening Instrument from one to 24 months in primary health care in Mexico. Salud Ment [online]. 2018, vol.41, n.2, pp.57-63. ISSN 0185-3325.


Early identification of developmental delays or disabilities in children is a challenge and a global concern. In Mexico, the prevalence of childhood disability is 6%, and it is estimated that 25% of the unattended delays will have consequences on their potential. VANEDELA is a rapid screening test to detect and prevent developmental disorders in primary health care.


To determine the external validity and test-retest reliability of the behavioral (DB) and reflex (DR) developmental formats of the VANEDELA screening test, compared with the diagnostic test of Gesell’s Developmental Schedule Test.


Descriptive, transversal, and prospective study in 379 infants aged one to 24 months attending the Neurodevelopment Monitoring Laboratory / INP and the ISSSTE Tlalpan Family Medicine Clinic from 2011 to 2014. Measurements: A set of four aspects was evaluated including validity by external criteria: sensitivity, specificity, positive-negative predictive criteria, and test-retest reliability.


In the DB format, we found a 79% - 89% sensitivity (S) and a 83% - 95% specificity (Sp). In the DR format, a 18% - 35% sensitivity and a 81% - 96% specificity were found. Using both DB-DR formats, we found a 82% - 89% sensitivity and 72% to 91% specificity, and a test-retest reliability .62-1.

Discussion and conclusion:

The VANEDELA increased its validity parameters with respect to the previous assessment with adequate stability. The DB formats and the DB-DR combination of VANEDELA have an adequate validity based on external criteria, making them suitable for use in primary health care.
