Insights

The ESSENCE Questionnaire (ESSENCE-Q) effectively screens for early neurodevelopmental disorders in Japanese infants. Professional assessments using ESSENCE-Q are reliable at 18 and 36 months, but maternal input requires professional supplementation.

Area of Science:

  • Pediatric Neurodevelopment
  • Developmental Psychology
  • Public Health Screening

Background:

  • Early detection of neurodevelopmental disorders is crucial for timely intervention.
  • The ESSENCE Questionnaire (ESSENCE-Q) is designed to identify early signs across developmental domains.
  • Validating ESSENCE-Q in diverse populations, like Japanese infants, is essential.

Purpose of the Study:

  • To evaluate the feasibility, reliability, accuracy, and reproducibility of the ESSENCE Questionnaire (ESSENCE-Q) in 18- and 36-month-old Japanese infants and toddlers.
  • To assess the performance of ESSENCE-Q completed by mothers, public health nurses, and psychologists.
  • To establish optimal cut-off values for ESSENCE-Q in the Japanese population.

Main Methods:

  • Longitudinal analysis of data from 1373 children at 18- and 36-month health check-ups.
  • Independent completion of ESSENCE-Q by mothers (ESSENCE-Q-M), public health nurses (ESSENCE-Q-N), and psychologists (ESSENCE-Q-P).
  • Evaluation of effectiveness using receiver operating characteristic curves.

Main Results:

  • Overall neurodevelopmental disorder prevalence was 11.2%.
  • ESSENCE-Q demonstrated good internal consistency.
  • Psychologist-completed ESSENCE-Q (ESSENCE-Q-P) showed the highest performance at 18 months; both nurse- (ESSENCE-Q-N) and psychologist-completed (ESSENCE-Q-P) versions performed excellently at 36 months.
  • Maternal completion alone (ESSENCE-Q-M) was insufficient for standalone use.

Conclusions:

  • The ESSENCE Questionnaire (ESSENCE-Q) is a highly useful and reproducible screening tool for professionals conducting 18- and 36-month check-ups.
  • ESSENCE-Q completed by mothers requires supplementation with professional assessments for accurate neurodevelopmental disorder screening.
  • This study validates ESSENCE-Q as a valuable tool for early detection in Japanese infants and toddlers.
