Validation of the Dominican system for measuring early childhood development.

Background: The purpose of the study was to determine the psychometric properties of the Dominican System for Measuring Early Childhood Development (SIMEDID, for its Spanish acronym), to adjust the sequence of item presentation, and to provide age-standardized norms for each item, to enable policy and program managers to make decisions based on specific and structured data.

Methods: After approval from an ethics committee, a total of 948 children from 0 to 60 months participated in this study. Participants were evaluated on four early childhood development domains (gross motor, fine motor, language development, and socio-emotional development).

The impact of ever breastfeeding on children ages 12 to 36 months: A secondary data analysis of the standardization study of the Dominican system for evaluating early childhood development.

Extensive research has shown that breastfeeding offers many benefits to children, including advantages in lifelong health, physical development, cognitive function, behavior, and brain development, compared to those not breastfed. In the Dominican Republic, the prevalence of exclusive breastfeeding among infants aged 0-6 months remains low, and the lack of a surveillance system has made it challenging to measure the impact of breastfeeding on early childhood development (ECD). This study aims to address the effect of ever breastfeeding on ECD.

Increase in abundance and decrease in richness of soil microbes following Hurricane Otto in three primary forest types in the Northern Zone of Costa Rica.

Little is known of how hurricane-induced deposition of canopy material onto tropical forest floors influences the soil microbial communities involved in decomposition of these materials. In this study, to identify how soil bacterial and fungal communities might change after a hurricane, and their possible roles in the C and N cycles, soils were collected from five 2000 m2 permanent plots in Lowland, Upland and Riparian primary forests in Costa Rica 3 months before and 7 months after Hurricane Otto damaged the forests. The soil Water, inorganic N and Biomass C increased and total organic C decreased Post-Hurricane, all of which best predicted the changes in the Post-Hurricane soil microbial communities.

Dimensional structure and measurement invariance of the BRIEF-2 across gender in a socially vulnerable sample of primary school-aged children.

The present study aims to analyze, on the one hand, the dimensional structure of the BRIEF-2 and, on the other, its measurement invariance across gender in a sample of primary school-aged children. Participants were 168 students (51.8% girls) in conditions of social risk and in foster homes, with ages ranging from 6 to 15 years old (M = 10.
