Receptive language skills among young children in rural Guatemala: The relationship between the Test de Vocabulario en Imagenes Peabody and a translated and adapted version of the Mullen Scales of Early Learning

摘要

Abstract Background Children in low‐ and lower middle income countries (LMICs) often have poorer language skills compared with children from high‐income countries. Limited availability of culturally and linguistically appropriate assessment measures in LMICs, especially for young children, can hinder early identification and prevention efforts. Here, we describe receptive language (RL) skills among young children in rural Guatemala and report on the validity of a translated and culturally adapted developmental measure of RL. Methods Children ( n ?=?157; m ?=?53.6?months, range ?=?42–68?months) enrolled in a prospective cohort study of postnatally acquired Zika virus infection were administered the Test de Vocabulario en Imagenes Peabody (TVIP) and the RL scale from a translated and adapted version of the Mullen Scales of Early Learning (MSEL). Performance on the TVIP was compared with the Latin American normative sample. Correlational analysis examined the relationship between performance on the TVIP and the MSEL‐RL. Results Mean scores were significantly below the normative sample mean on the TVIP, t (126)?=??11.04, p ??.001; d ?=?1.00. Performance on the TVIP among children who passed the practice items ( n ?=?127) was significantly positively associated with performance on the MSEL‐RL ( r ?=?.50, p ??.001), but not significantly associated with age or gender. Older age ( p ??.0001) and female gender ( p ?=?.018) were associated with passing the TVIP practice items. Conclusions Delays in RL vocabulary were identified among young children in rural Guatemala on the TVIP. The association between scores on the TVIP and the RL scale of the MSEL provides preliminary support for the construct validity of this translated and adapted version of the MSEL.
