The Pediatric Symptom Checklist-17 (PSC-17) is a widely used, briefer version of the PSC-35, a parent-completed measure of children's psychosocial functioning. Despite the extensive use of the PSC-17 over the past 15 years there has not been a large-scale replication of the original derivation study.

CONCLUSIONS: Minimally trained PCPs can administer the M-CHAT/F reliably and efficiently during regular well-child visits, increasing PPV without compromising detection.
