A repeated cross-sectional study of clinicians' use of psychotherapy techniques during 5years of a system-wide effort to implement evidence-based practices in Philadelphia

BackgroundLittle 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 5years 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.MethodUsing 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 5years (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.ResultsClinicians were 80% female and averaged 37.52years 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).ConclusionsSystem 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.
