Created by W Gardner and K Kelleher (1999), and based on PSC by M Jellinek et al. (1988)
Formatted by R Hilt, inspired by Columbus Children’s Research Institute formatting of PSC-17
Suggested Screen Cutoff:
PSC-17 - I ≥ 5
PSC-17 - A ≥ 7
PSC-17 - E ≥7
Total Score ≥ 15
Higher Scores can indicate an increased
likelihood of a behavioral health disorder
being present.

The PSC-17 can help primary care providers assess the likelihood of finding any mental
health disorder in their patient. The brief and easy to score PSC-17 has fairly good mental
health screening characteristics, even when compared with much longer instruments like the
CBCL (Child Behavior Checklist by T. Achenbach).
A 2007 study in primary care offices compared use of the PSC-17 to simultaneous use of the
CBCL in 269 children aged 8-15, showing reasonably good performance of its three
subscales compared to similar subscales on the CBCL. The gold standard here was a K-
SADS diagnosis, which is a standardized psychiatric interview diagnosis. These comparison
statistics are summarized below, with positive and negative predictive values shown based
on different presumed prevalence (5 or 15%) of the disorders. Providers should notice that
despite its good performance relative to longer such measures, it is not a foolproof diagnostic
aide. For instance the sensitivity for this scale only ranges from 31% to 73% depending on
the disorder in this study:
