Predictive Validity of Developmental Screening Questionnaires for Identifying Children With Later Cognitive or Educational Difficulties: A Systematic Review.

Parent/caregiver completing developmental screening questionnaires (DSQs) for children before 5 years of age is currently recommended. The DSQs recommended by the American Academy of Pediatrics (AAP) are the Ages and Stages Questionnaires (ASQ), Parents' Evaluation of Developmental Status (PEDS), and the Survey of Well-being of Young Children (SWYC). Nevertheless, their predictive validity has not been well-established. To assess in the current literature, the value of AAP-recommended DSQs (ASQ, PEDS, SWYC) administered between 0 and 5 years of age, for predicting long-term cognitive achievement and/or school performance (CA/SP), after 1 year or more of evaluation and at/or after age 5 years, in the general population. Cochrane, MEDLINE PubMed, CINAHL, EMBASE, Web of Science, Scielo, and Scopus databases (until March 2021). Two authors selected the studies. Forward and backward citation follow-up was done; authors of DSQ were contacted to identify additional studies. Cohorts were identified, and authors of selected studies were contacted to corroborate and complete extracted data. Thirty-two publications, corresponding to 10 cohorts, were included. All cohorts used ASQ. Only cohort using PEDS was identified but did not meet the inclusion criteria. No cohorts conducted with SWYC were identified. Associations between ASQ and CA/SP were extracted for eight cohorts. The odds ratios were >3, and the area under the curve was 0.66-0.87. A trade-off between sensitivity and specificity was observed. Heterogeneity in population characteristics and in DSQ adaptations. A positive association between ASQ and later CA/SP was found in different social, cultural, and economic settings. Additional studies are necessary to determine the impact factors in the predictive capacity of DSQs. PROSPERO, identifier: CRD42020183883.
