Abstract

GUDIEL-HERMOZA, Adriel; GUDIEL-HERMOZA, Jorge  and  GUILLEN-PINTO, Daniel. Adaptation, validation and cut-off values of the Ages & Stages questionnaire 3th edition (ASQ-3) Spanish version in a Lima, Perú urban setting. Rev Neuropsiquiatr [online]. 2021, vol.84, n.2, pp.83-93. ISSN 0034-8597.  http://dx.doi.org/10.20453/rnp.v84i2.3995.

Objective

: A cultural-linguistic adaptation of the Age and Stages Questionnaire third edition (ASQ-3)-Spanish version was performed in order to determine its reliability, validity and cut-off points in an urban population and pediatric outpatient setting of Lima, Perú.

Material and Methods

: Questionnaire forms were applied to parents of children between 1 to 66 months old of age, chosen through a convenience sampling method.

Results

: A total of 5,830 questionnaires were applied to parents of 3,507 children, 2 667 (45.7%) of whom had between 14 and 36 months of age. The general internal consistency and that of five specific areas, measured by means of the Ordinary alpha index oscillated between 0.70-0.94. Content validity by judges’ criteria, using the index by Lawshe method, the Aiken V coefficient, or both, was valid for most of the questionnaires. The biserial item-test correlations were > 0.30 for most items (p <0.010). The construct validity according to the factorial analysis, determined that the five factors or areas of the ASQ-3 were adequate. Cut-off points were determined by age and area intervals of the ASQ-

Conclusions

: The Spanish version of the ASQ-3 proved to be a reliable and valid tool to survey and screen the psychomotor development of children under 5 years of age in an urban outpatient area setting of Lima, Perú.

Keywords : ASQ-3; children; psychomotor development; validity; reliability.
