Identifying True Developmental Screening Tools
Developmental screening tools are quick, low-cost instruments used to identify children who may be at risk of a developmental delay and need further evaluation. They are distinct from developmental assessment/diagnostic tools, which are detailed, time-consuming instruments administered by trained professionals to confirm a diagnosis and characterize the nature/severity of a delay.
- Denver-II: A widely used, direct-observation developmental screening test administered by a health worker to children aged 0–6 years, covering personal-social, fine motor, language, and gross motor domains.
- Ages and Stages Questionnaire (ASQ): A parent-completed screening questionnaire series used to flag possible developmental delays in children aged 1 month to 5.5 years.
- Parents' Evaluation of Developmental Status (PEDS): A brief, parent-report screening tool used from birth to 8 years to elicit and score parental concerns about a child's development.
- Bayley Scale for Infant and Toddler Development (Bayley-III/IV): This is a comprehensive, standardized diagnostic/assessment tool administered by trained specialists to precisely measure a child's cognitive, language, and motor development — it is used for in-depth evaluation and diagnosis, not for quick screening.
Why the Answer is 1, 2 and 3
Denver-II, ASQ, and PEDS are all validated, widely recommended developmental screening instruments used in primary care and community settings to quickly triage children for further work-up. The Bayley Scale, by contrast, is a lengthy, resource-intensive diagnostic assessment tool used after screening flags a possible concern — it is not itself a screening instrument.
Therefore, the correct combination is 1, 2 and 3, corresponding to Option D.
Why the Other Options are Incorrect
- Option A (2, 3 and 4): Incorrect — it wrongly includes the Bayley Scale (a diagnostic tool) and omits Denver-II (a true screening tool).
- Option B (1, 2 and 4): Incorrect — it wrongly includes the Bayley Scale and omits PEDS.
- Option C (1, 3 and 4): Incorrect — it wrongly includes the Bayley Scale and omits ASQ.
