Insights

The Trivandrum Development Screening Chart for children 0-6 years (TDSC (0-6 y)) is a reliable tool for identifying developmental delays in young children. This validated screening method supports early intervention for better child development outcomes.

Area of Science:

  • Pediatrics
  • Developmental Pediatrics
  • Public Health

Background:

  • Developmental delay affects a significant number of children globally.
  • Early identification and intervention are crucial for improving developmental outcomes.
  • Existing screening tools may have limitations in community settings.

Purpose of the Study:

  • To develop a simple screening tool for identifying developmental delay in children aged 0-6 years.
  • To validate the efficacy of the Trivandrum Development Screening Chart for children 0-6 years (TDSC (0-6 y)) in a community setting.

Main Methods:

  • The TDSC (0-6 y), comprising 51 items, was developed based on existing developmental norms.
  • Criterion validity was assessed using the Denver Developmental Screening Test (DDST) as a reference standard.
  • A community sample of 1,183 children aged 0-6 years participated in the validation study.

Main Results:

  • The TDSC (0-6 y) demonstrated a sensitivity of 84.62% and specificity of 90.8% for identifying developmental delay.
  • The tool achieved a Negative Predictive Value of 99.23%.
  • Good test-retest (ICC=0.77) and inter-rater (ICC=0.97) reliability were observed.

Conclusions:

  • The TDSC (0-6 y) is a simple, reliable, and valid screening tool for community use.
  • It effectively identifies children aged 0-6 years with developmental delay.
  • The tool facilitates early intervention practices for improved child development.

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,...

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...
