Participants (N=80) were children (ages 6-11) referred for treatment due to moderate elevations (≥75th percentile) on the externalizing subscale of the Pediatric Symptom Checklist (PSC-17). The sample was recruited from six pediatric practices in an urban setting. The treatment (Protocol for an Office-based Nurse-administered Intervention; PONI) was administered on-site by trained nurses over the course of 3-6months. Overall, symptom reduction from the first session to last session was moderate (ES=0.61) and gradual. Roughly two-thirds (72%) of symptom reduction took place over the first 8weeks of treatment. The average trajectory of symptom reduction was characterized by a negative slope that flattened over time, consistent with a quadratic growth model. Initial symptom severity predicted final symptom severity (r=.36, P<.01), even though patients with greater initial symptom severity remained in treatment for a significantly greater number of sessions (r=.24, P<.05). The implications of these findings for enhancing the efficiency and effectiveness of treatment are discussed.
