Insights

The Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations-Questionnaire (ESSENCE-Q) shows good reliability for early screening of neurodevelopmental disorders in children under six. Optimal cutoff points are proposed to improve diagnostic accuracy in clinical settings.

Area of Science:

  • Child and Adolescent Psychiatry
  • Developmental Pediatrics
  • Neurodevelopmental Disorders

Background:

  • Early identification of neurodevelopmental disorders like autism is crucial but often delayed.
  • The "wait-and-see" approach hinders timely diagnosis.
  • The Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations-Questionnaire (ESSENCE-Q) is a brief screening tool designed to expedite this process.

Purpose of the Study:

  • To estimate the reliability of the ESSENCE-Q.
  • To evaluate the author-suggested clinical cutoff levels for the ESSENCE-Q.
  • To propose optimal cutoff levels using receiver operating characteristic analysis.

Main Methods:

  • The ESSENCE-Q was administered for one year to children under six referred for developmental concerns in Kochi, Japan.
  • Clinical diagnostic assessments were conducted concurrently.
  • Results were compared between 130 children assessed with the ESSENCE-Q and clinical diagnoses.

Main Results:

  • The ESSENCE-Q demonstrated good reliability with a Cronbach's alpha of 0.82.
  • Initial sensitivity was 0.94 and specificity was 0.53.
  • An optimal cutoff of ESSENCE-Q score ≥2 (yes) or ≥3 (maybe/a little) yielded 0.87 sensitivity and 0.77 specificity.

Conclusions:

  • The ESSENCE-Q is a valuable screening instrument for early identification of neurodevelopmental disorders in clinical practice.
  • Further research, including case-control and general population studies across diverse age groups, is needed to confirm broader validity and reliability.
