Insights

The Korean Developmental Screening Test (K-DST) shows promise for identifying developmental delays in very-low-birth-weight (VLBW) infants. This tool can aid in early referral for neurodevelopmental assessments.

Area of Science:

  • Neonatal care and developmental pediatrics.
  • Neurodevelopmental outcomes in preterm infants.

Background:

  • Improved survival rates for very-low-birth-weight (VLBW) infants necessitate robust neurodevelopmental outcome assessment.
  • Early identification of developmental delays is crucial for timely intervention in VLBW populations.

Purpose of the Study:

  • To evaluate the diagnostic validity of the Korean Developmental Screening Test (K-DST) for VLBW infants.
  • To determine the K-DST's effectiveness in predicting neurodevelopmental delays compared to established measures.

Main Methods:

  • Analysis of data from 173 VLBW infants in the Korean Neonatal Network (2012-2014).
  • Comparison of K-DST results against the Bayley Scales of Infant Development-II (BSID-II).
  • Calculation of sensitivity, specificity, and predictive values for K-DST domains.

Main Results:

  • K-DST failure in multiple domains showed moderate sensitivity (60.3-73.2%) and NPV (71.6-75.0%) for identifying delays (MDI/PDI <85).
  • Individual K-DST domains correlated better with predicting mental developmental index (MDI) delays than psychomotor developmental index (PDI) delays.
  • The frequency of K-DST domain failure aligned with BSID-II PDI <85 criteria.

Conclusions:

  • The K-DST is a potentially useful screening tool for identifying mental developmental delays in VLBW infants.
  • The K-DST can facilitate timely referrals for comprehensive neurodevelopmental evaluations in high-risk infants.

Birth Control Methods01:22

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Weighted Mean00:57

Weighted Mean

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

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,...

Mass and Weight01:19

Mass and Weight

Mass and weight are often used interchangeably in everyday conversation. For example,  medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...
