Further understanding of their relative influence and pathways is needed to inform the design of interventions targeting ECD. Methods We conducted path analyses of factors associated with 18-month language and motor development in four prospective cohorts of children who participated in trials conducted as part of the International Lipid-Based Nutrient Supplements (iLiNS) Project in Ghana (n = 1,023), Malawi (n = 675 and 1,385), and Burkina Faso (n = 1,122). In two cohorts, women were enrolled during pregnancy. In two cohorts, infants were enrolled at 6 or 9 months. In multiple linear regression and structural equation models (SEM), we examined 22 out of 44 factors identified in previous reviews, plus 12 additional factors expected to be associated with ECD. Results Out of 42 indicators of the 34 factors examined, 6 were associated with 18-month language and/or motor development in 3 or 4 cohorts: child linear and ponderal growth, variety of play materials, activities with caregivers, dietary diversity, and child hemoglobin/iron status. Factors that were not associated with child development were indicators of maternal Hb/iron status, maternal illness and inflammation during pregnancy, maternal perceived stress and depression, exclusive breastfeeding during 6 months postpartum, and child diarrhea, fever, malaria, and acute respiratory infections. Associations between socioeconomic status and language development were consistently mediated to a greater extent by caregiving practices than by maternal or child biomedical conditions, while this pattern for motor development was not consistent across cohorts. Conclusions Key elements of interventions to ensure quality ECD are likely to be promotion of caregiver activities with children, a variety of play materials, and a diverse diet, and prevention of faltering in linear and ponderal growth and improvement in child hemoglobin/iron status.

The reliability and validity of the social responsiveness scale to measure autism symptomology in Vietnamese children / Phuong H. NGUYEN in Autism Research, 12-11 (November 2019)  

Public ISBD [article]  inAutism Research > 12-11 (November 2019) . - p.1706-1718 Titre : The reliability and validity of the social responsiveness scale to measure autism symptomology in Vietnamese children Type de document : texte imprimé Auteurs : Phuong H. NGUYEN, Auteur ; M.E. OCANSEY, Auteur ; Meghan MILLER, Auteur ; Dung T.K. LE, Auteur ; Rebecca J. SCHMIDT, Auteur ; Elizabeth L. PRADO, Auteur Article en page(s) : p.1706-1718 Langues : Anglais (eng) Mots-clés : Social Responsiveness Scale  Vietnam  autism spectrum disorder  low- and middle-income countries  reliability  validity Index. décimale : PER Périodiques Résumé : The Social Responsiveness Scale (SRS) has been validated in high-income countries but not yet in low- and middle-income countries. We aimed to assess the reliability of the SRS in a community sample and its validity to discriminate between children with and without autism spectrum disorder (ASD) in Vietnam. We used a three-phase study: piloting the translated SRS, reliability testing, and validation of the SRS in 158 Vietnamese caretakers and their children (ages 4-9 years). We examined reliability, validity and sensitivity, and specificity to ASD diagnosis. We applied receiver operator characteristic (ROC) analysis to determine optimal cutoff scores discriminating the children with ASD from those without ASD. We also assessed the performance of the SRS short form. We found that reliability was good with high internal consistency (0.88-0.89), test-retest reliability (0.82-0.83), sensitivity (93%), and specificity (98%) for identification of children with ASD. The ROC curves were similar for total raw score and total T-score, with the area under the curve (AUC) values reaching 0.98 and the optimal cutoff of 62 for raw scores and 60 for T-scores. The SRS short form also performed well in distinguishing children with ASD from children without ASD, with high AUC (0.98), sensitivity (90%), and specificity (98%) when using a raw score of 15 as a cutoff. In conclusion, the translated and culturally adapted SRS shows good reliability, validity, and sensitivity for identification of children with ASD in Vietnam. Both SRS long and short forms performed adequately to discriminate between children with and without ASD. Autism Res 2019, 00: 1-13. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Middle-income countries often lack validated tools to evaluate autism symptoms. The Social Responsiveness Scale (SRS) translated to Vietnamese was reliable and performed well to distinguish between children with and without autism spectrum disorder in Vietnam. The Vietnamese SRS, and translations of the tool to other languages with this methodology, may be useful in pediatric practice, potentially allowing providers to make more appropriate referrals for diagnostic evaluations and identify children for intervention to help them fulfill their developmental potential.
