[A new method for evaluating psychomotor development based on information from parents. The Spanish version of the Kent Infant Development Scale].

OBJECTIVE

The purpose of this dissertation research was to design, standardize and validate the Spanish version of the Kent Infant Development Scale (KIDS).

PATIENTS AND METHODS

This questionnaire is based on information obtained from the parents. It was translated into Spanish and named "Escala de Desarrollo Infantil de Kent" (EDIK). The EDIK normative data were collected from the parents of 662 healthy infants (ages 1 to 15 months) in pediatric clinics in Catalonia (Spain).

RESULTS

Test-retest reliability (r = 0.99; p < 0.001), interjudge reliability (r = 0.98; p < 0.001) and internal consistency (Cronbach alpha = 0.9947) were determined. An "r' of 0.96 was obtained when EDIK scores were compared to their estimated developmental ages obtained from the Denver Developmental Scale. The correlation of the infants' chronological age and their EDIK was 0.96 (p < 0.001).

CONCLUSIONS

The high reliability and validity correlation coefficients demonstrate the sound psychometric properties of the EDIK. It appears to be a useful and acceptable instrument in measuring the developmental status of infants by using the reports of their parents.
