Objective: This analysis assessed whether stimulant adherence was associated with improvement in academic grade point average (GPA) among children diagnosed with and treated for attention-deficit/hyperactivity disorder (ADHD). Method: Medicaid claims were merged with academic records from Philadelphia public schools of Medicaid-eligible children in first through eighth grades who were diagnosed with ADHD and who had filled one or more stimulant prescription. Students diagnosed with mental retardation, autism, or speech, hearing, visual, or language impairments were excluded. Marking periods were scored for GPA (range: 0-4.0) based on English, mathematics, social studies, and science grades and for stimulant adherence (medication possession ratio > 0.70). Random and fixed-effects models estimated the effects of stimulant adherence on GPA, between all adherent and nonadherent marking periods in aggregate and within individual student's marking periods, respectively. Results: A total of 3,543 students contributed 29,992 marking periods, of which 18.6% were adherent. Mean GPA was significantly higher during stimulant-adherent (2.18) than stimulant-nonadherent (1.99) marking periods in aggregate (p < .0001). The regression coefficient representing within-student association between stimulant adherence and GPA over time was 0.108 (p < .0001), indicating that adherence was associated with a 0.108 increase in GPA. In stratified analyses, analogous coefficients were 0.106 for boys, 0.111 for girls, 0.078 for elementary students, and 0.118 for middle school students (all p < .0001). The association was stronger among students with (0.139) than without (0.088) comorbid disruptive behavior disorders (both p < .0001). Conclusions: Stimulant adherence, although found to be low among urban elementary and middle school students diagnosed with ADHD, was associated with a marginal improvement in GPA. J. Am. Acad.

Background: Little work investigates the effect of behavioral health system efforts to increase use of evidence-based practices or how organizational characteristics moderate the effect of these efforts. The objective of this study was to investigate clinician practice change in a system encouraging implementation of evidence-based practices over 5 years and how organizational characteristics moderate this effect. We hypothesized that evidence-based techniques would increase over time, whereas use of non-evidence-based techniques would remain static.Method: Using a repeated cross-sectional design, data were collected three times from 2013 to 2017 in Philadelphia's public behavioral health system. Clinicians from 20 behavioral health outpatient clinics serving youth were surveyed three times over 5 years (n = 340; overall response rate = 60%). All organizations and clinicians were exposed to system-level support provided by the Evidence-based Practice Innovation Center from 2013 to 2017. Additionally, approximately half of the clinicians participated in city-funded evidence-based practice training initiatives. The main outcome included clinician self-reported use of cognitive-behavioral and psychodynamic techniques measured by the Therapy Procedures Checklist-Family Revised.Results: Clinicians were 80% female and averaged 37.52 years of age (SD = 11.40); there were no significant differences in clinician characteristics across waves (all ps > .05). Controlling for organizational and clinician covariates, average use of CBT techniques increased by 6% from wave 1 (M = 3.18) to wave 3 (M = 3.37, p = .021, d = .29), compared to no change in psychodynamic techniques (p = .570). Each evidence-based practice training initiative in which clinicians participated predicted a 3% increase in CBT use (p = .019) but no change in psychodynamic technique use (p = .709). In organizations with more proficient cultures at baseline, clinicians exhibited greater increases in CBT use compared to organizations with less proficient cultures (8% increase vs. 2% decrease, p = .048).Conclusions: System implementation of evidence-based practices is associated with modest changes in clinician practice; these effects are moderated by organizational characteristics. Findings identify preliminary targets to improve implementation. [ABSTRACT FROM AUTHOR]
