“…Several meta-analytic reviews of anxiety disorder treatment have found modest efficacy for cognitive-behavioral interventions (e.g., Carpenter et al, 2018); however, dropout rates for CBT in PTSD treatment were differentially higher than for other disorders. Glowacki and Glowacki (2022) report dropout rates for Cognitive Processing Therapy in the management of PTSD to be as high as 50%, considerably higher than those reported in the Carpenter et al ( 2018) meta-analysis. Most such discontinuation occurs early in treatment before the patient begins to notice improvement.…”
