Results:
Adherence to psychotherapy was associated with reduction in seizure frequency (84% in adherent group vs 61% in nonadherent; P = .021), improvement in quality of life (P = .044), and reduction in ED utilization (P = .040), with medium effect sizes; there was no difference in PNES freedom. The association between adherence and ≥50% reduction in PNES frequency persisted when controlling for potential confounders in a multivariate model. Psychotherapy nonadherence was associated with baseline characteristics of self-identified minority status (odds ratio: 7.47; P = .019) and history of childhood abuse (odds ratio: 3.30; P = .023).
