Abstract
OBJECTIVE: All children in England should receive a health review at 2-2½ years, with the Ages and Stages Questionnaire third edition (ASQ-3) used to collect public health surveillance data on child development. However, practitioners also value tools that assess individual children's development-consistent with ASQ-3's original purpose. Concerns about licensing costs and barriers to digitalisation have prompted interest in alternative tools to the ASQ-3 in England. DESIGN: To inform policy, we conducted a rapid scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines to identify tools that can measure or assess early child development. DATA SOURCES: Searched PubMed, PsycINFO and Web of Science from January 2012 to November 2022, with targeted search update November 2024. ELIGIBILITY CRITERIA: We included English-language studies published after January 2012 that described or evaluated tools in English which could measure or assess early child development in children <5 years across five domains: motor, cognitive, communicative, social and emotional. DATA EXTRACTION: We extracted key features and reliability, validity, sensitivity and specificity of tools which could feasibly be implemented at the 2-2½-year review (eg, including multiple age versions and <30 min to use). We used Quality Assessment of Diagnostic Accuracy Studies-I to assess risk of bias. RESULTS: We identified 112 unique publications describing 34 tools; six met our feasibility criteria for the 2-2½-year review (reported in 53 studies). Only ASQ-3 and CREDI offer domain-specific scoring-a government priority. ASQ-3 moderately detects mild delays and performs better for severe delays in at-risk groups. Caregiver Reported Early Development Instruments (CREDI) was designed for public health surveillance, and we do not yet know how it performs for individual assessment. CONCLUSIONS: ASQ-3 and CREDI are most promising for use at the 2-2½-year review. However, we lack UK-based validation and norming studies, even for ASQ-3. Ultimately, careful implementation and integration into existing systems will determine a tool's value for identifying developmental needs, supporting families and producing high quality data for public health surveillance.
