Equating Children’s PPVT Scores Across Survey Rounds and Age Cohorts in Peru

Young Lives gathers information from children and families through household and child questionnaires as well as children’s cognitive and achievement tests. The Peabody Picture Vocabulary Test (PPVT) has been used in all survey rounds to date and with both age cohorts. This technical note presents the psychometric analysis performed (using Item Response Theory, IRT) in order to build cognitive measures comparable across Rounds 2 and 3 and the Younger and Older Cohorts for Peru. To achieve this, a one-parameter IRT model was used.

Cross-Sectional and Longitudinal Associations between Household Food Security and Child Anthropometry at Ages 5 and 8 Years in Ethiopia, India, Peru, and Vietnam

Background: Poor childhood nutritional status has lifetime effects and food insecurity is associated with dietary practices that can impair nutritional status.

Objectives: We assessed concurrent and subsequent associations between food insecurity and height-for-age z scores (HAZs) and body mass index?for-age z scores (BMI-Zs); evaluated associations with transitory and chronic food insecurity; and tested whether dietary diversity mediates associations between food insecurity and nutritional status.

What Can Comparative Country Research Tell Us About Child Poverty?

We are frequently asked why Young Lives is conducting research in four countries, and why specifically Ethiopia, India (in the states of Andhra Pradesh and Telangana), Peru and Vietnam. This short paper attempts to answer these questions.

Socio-economic Status and Early Childhood Cognitive Skills: Is Latin America Different?

This paper documents differences in cognitive development – as measured by a receptive vocabulary test ? between children from households with high and low socioeconomic status (SES) in two different phases of childhood (before and after early school years) in four developing countries: Peru, Ethiopia, India and Vietnam. Intercontinental evidence on the timing, pattern, and persistence of these differences is provided.

How Gender Shapes Adolescence: Diverging Paths and Opportunities

A global policy focus since 2000 on the first decade of children's lives has resulted in impressive achievements, including dramatic reductions in child mortality and the expansion of primary schooling. To uphold and build upon these gains, however, a new focus is needed on the crucial period of adolescence, when gender differences widen, particularly for the poorest children, and decisions are made around education, work, marriage and fertility that have a critical impact on long-term outcomes for girls and boys.

Bilingual Education in Latin America

This paper uses Peruvian school-level data from the Young Lives international study of childhood poverty to investigate the effect of Quechua-medium instruction on academic achievement. We estimate an education production function and find that indigenous children who attend Quechua-medium schools achieve mathematics scores 0.54 standard deviations higher than indigenous children who attend Spanish-medium schools. We find weak and inconclusive evidence that indigenous children who attend Quechua-medium schools attain higher language test scores.
