Abstract

The present study examined whether certain Veterans Health Administration (VHA) therapists have more success than others in keeping patients engaged in evidence-based psychotherapies for posttraumatic stress disorder (PTSD). Our objective was to use multilevel modeling to quantify the variability between therapists in two indicators of patient engagement: early dropout (i.e., < 3 sessions) and adequate dose (i.e., ≥ 8 sessions). The phenomenon of systematic variability between therapists in patients’ treatment experience and outcomes is referred to as “therapist effects.” The sample included the 2,709 therapists who provided individual cognitive processing therapy (CPT) or prolonged exposure (PE) to 18,461 veterans with PTSD across 140 facilities in 2017. Data were extracted from administrative databases. For CPT, therapist effects accounted for 10.9% of the variance in early dropout and 8.9% of the variance in adequate dose. For PE, therapist effects accounted for 6.0% and 8.8% of the variance in early dropout and adequate dose, respectively. Facility only accounted for an additional 1.1%–3.1% of the variance in early dropout and adequate dose. For CPT, patients’ odds of receiving an adequate dose almost doubled, OR = 1.41/0.72 = 1.96, if they were seen by a therapist in the highest compared with the lowest retention decile. For PE, the odds of a patient receiving an adequate dose were 84% higher, OR = 1.38/0.75 = 1.84, when treated by a therapist in the highest compared with the lowest retention decile. Therapist skills and work environment may contribute to variability across therapists in early dropout and adequate dose.
