Parent screening questionnaires to detect cognitive and language delay at 2 years in high-risk infants: an analysis from the Victorian Infant Collaborative Study 2016-2017 cohort.

Neither screening questionnaire identified cognitive delay well, but both were better at identifying language delay. The PARCA-R detects delay on the Bayley-III more accurately than the ASQ-3. Sensitivity for detecting delay is greatest when the PARCA-R and ASQ-3 were used in combination, but resulted in lower specificity.
