    The Prescreening Developmental Questionnaire (PDQ) effectively identifies children needing further developmental screening. This tool accurately flags potential issues, reducing unnecessary tests and saving valuable clinical time.

    Area of Science:

    • Pediatrics
    • Developmental Psychology
    • Public Health

    Background:

    • Periodic developmental screening is crucial for early identification of developmental delays.
    • The Denver Developmental Screening Test (DDST) is a standard tool but can be time-consuming.
    • A need exists for an efficient prescreening tool to optimize the screening process.

    Purpose of the Study:

    • To develop and validate the Prescreening Developmental Questionnaire (PDQ) as an initial step for developmental screening.
    • To assess the PDQ's accuracy in identifying children who require a full DDST.
    • To evaluate the efficiency and acceptance of the PDQ among parents and healthcare providers.

    Main Methods:

    • Adapted 97 DDST items into 10 age-appropriate questions for the PDQ.

  • Administered the PDQ to 1,155 parents, followed by DDST evaluation of their children.
  • Conducted a field trial with 1,027 PDQs in clinical settings.

    • Main Results:

    • High agreement (mean 93.3%) between parental PDQ responses and DDST items.
    • PDQ identified 31.2% of children for DDST, including 86.7% of abnormal and 53.8% of questionable DDSTs.
    • Referral predictive value was 23.3% in initial testing and 24.7% in a field trial; PDQ was well-received and reduced DDST administration by 69%.

    Conclusions:

    • The PDQ is a valid and efficient prescreening tool for developmental assessment.
    • It accurately identifies children needing further evaluation, optimizing resource allocation.
    • The PDQ improves screening efficiency and is favored by parents and physicians.
