Beyond Initial Screening: One-Year Follow-up of Adolescents with Internalizing Problems on the Pediatric Symptom Checklist.

Objective: Screening for adolescent depression is a quality indicator for pediatric care, and the parent-completed, 17-item Pediatric Symptom Checklist's internalizing (PSC-17P-INT) subscale has been validated for this purpose. The current study assessed the feasibility of PSC-17P-INT screening, the prevalence of risk on 2 consecutive PSC-17P-INTs, and rates of behavioral health (BH) service use before and after screening.

Methods: The parent-report PSC-17 was completed on tablet devices before well-child visits (WCVs) with results instantaneously available to clinicians in the electronic health record. Billing data were used to identify adolescents with 2 consecutive WCVs and possible BH service utilization 6 months before and after their first screen.

Results: In 2017, 1,068 adolescents (12-17 years old) were seen for a WCV, and 637 (59.6%) of them had one in 2018. Most (93.9%; N = 604) completed a PSC at both visits. Patients who scored positively on their first PSC-17P-INT were about 9 times more likely to receive subsequent BH services than patients who screened negative (24.3% vs 2.6%, χ2 = 59.65, p < 0.001). However, risk prevalence increased from the first (11.6%) to the second (14.9%) screen, and only 37.1% of at-risk patients remitted.

Conclusion: The current study demonstrated that screening adolescents for depression using the PSC-17P-INT was feasible and associated with a significant increase in BH treatment rates. The study also demonstrated that the PSC could be used to track adolescents at risk for depression, found that most youth who screened positive remained at risk 1 year later, and supported recent quality guidelines calling for annual depression screening and follow-up for adolescents with depression.
