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.  https://doi.org/10.17711/sm.0185-3325.2018.009.

Introduction:

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.

Objective:

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.

Method:

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.

Results:

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.
