Insights

The Korean-Developmental Screening Test (K-DST) is most utilized in children under 24 months. Encouraging K-DST use in older children and revising its format could improve developmental screening accuracy.

Area of Science:

  • Pediatric developmental screening
  • Child health surveillance

Background:

  • The Korean-Developmental Screening Test (K-DST) is a tool for assessing child development.
  • Understanding K-DST utilization patterns is crucial for optimizing early detection of developmental delays.

Purpose of the Study:

  • To analyze the number of K-DST test takers in a children's hospital over one year.
  • To examine K-DST usage based on child age, referral rates, and follow-up percentages.

Main Methods:

  • Retrospective analysis of 4,062 children undergoing K-DST at Woorisoa Children's Hospital (2015).
  • K-DST results categorized by standard deviations: further evaluation (<-2SD), follow-up (-2SD to -1SD), peer level (-1SD to 1SD), and high level (>1SD).
  • Analysis across seven age groups from 4 to 71 months.

Main Results:

  • Peak K-DST utilization and follow-up occurred in children under 24 months (62.3%).
  • The 30- to 41-month age group showed the highest referral rates for further evaluation.
  • A significant portion (78.2%) of children with initially suspicious delays demonstrated catch-up development in follow-up tests.

Conclusions:

  • K-DST use should be promoted, particularly for children older than 24 months.
  • Revising the additional questions to a multiple-choice format is recommended to reduce confusion.
  • A nationwide study is suggested for comprehensive K-DST evaluation and potential revision.

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
