VALIDITY OF PARENT-COMPLETED DEVELOPMENTAL SCREENING IN CHILDREN WITH NEW-ONSET EPILEPSY BELOW THE AGE OF 3
Bibliographic record
Abstract
Abstract BACKGROUND Infants with childhood-onset epilepsies, including epileptic encephalopathies, are at high risk of developmental challenges such as motor and language delays. There has been a growing focus on developmental screening instruments due to the association between delayed development and long-term adverse outcomes, including negative impacts on health-related quality of life, school achievement and social participation. Therefore, children with developmental delays should be referred as early as possible to rehabilitation services such as occupational, physical, or speech therapy. Developmental screening using standardized tools is recommended in order to identify the high-risk children that require additional developmental assessments. The Ages and Stages Questionnaires (ASQ), a parent-completed developmental screening tool, is one of the more cited and recommended developmental screening tools. However, its utility in children with early-onset epilepsy has yet to be validated. OBJECTIVES This study aimed to determine the validity of the ASQ for identifying children with new-onset epilepsy who require further professional developmental rehabilitation. DESIGN/METHODS Fifty infants (25 males) with seizure onset under 3 years of age were prospectively recruited. Parents completed the ASQ-3 before the first clinic appointment. The ASQ-3 evaluates 5 domains of development. An ASQ score below 2 standard deviations (SD) on any one of the domains was considered abnormal. Once completed, all infants were evaluated by a multidisciplinary team including neurologists, occupational therapists, and physical therapists to determine if they should be referred for further rehabilitation interventions. Accuracy of the ASQ was calculated in terms of sensibility, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS Mean age at the initial evaluation was 13.1 months (SD=8.22). Among the 50 infants, 36 (72%) received a score <-2 SD in at least one domain of the ASQ and 43 (86%) were referred for further rehabilitation services after the multidisciplinary assessment. The ASQ had a sensitivity of 81%, a specificity of 71%, a PPV of 93% and a NPV of 36% in identifying children with new-onset epilepsy who would require further rehabilitation services. CONCLUSION The ASQ, a well-known parent-completed developmental screening tool, when abnormal shows adequate validity for the identification of children with early-onset epilepsy who require developmental assessments and interventions by rehabilitation professionals. Our results also provide further evidence that development delay is the rule rather than the exception in infants with new onset epilepsy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
