The relationship between the ages and stages questionnaire, 3rd edition scores in early childhood and future cognitive abilities in young Nepalese children.

BACKGROUND

The Ages and Stages Questionnaire 3rd edition (ASQ-3) could be a feasible tool in resource-poor settings. Little is known on the relationship between scores on the ASQ-3 and later intellectual abilities in these settings.

AIMS

To examine the relationship between ASQ-3 scores during the first and second year of life and intellectual abilities at 4 years of age in Nepalese children.

METHODS

In a cohort of 600 children at-risk of stunting, the ASQ-3 was performed at 6-11 and 18-23 months, and the Wechsler Preschool and Primary Scales of Intelligence, fourth edition (WPPSI-IV) at 4 years. We examined the relationship between the ASQ-3 scores and WPPSI-IV full scale IQ (FSIQ) using Spearman correlation coefficients and linear regression models.

RESULTS

Correlations between ASQ-3 total scores and FSIQ was 0.17 (95% CI 0.07, 0.27) at 6-11 and 0.34 (95% CI 0.26, 0.44) at 18-23 months explaining 2 and 12% of the variance respectively. Except for the communication subscale at 18-23 months with moderate correlations, correlations between the ASQ-3 subscales and FSIQ were weak.

CONCLUSION

Our findings suggest a modest relationship between ASQ-3 scores in early childhood and intellectual abilities at 4 years.
