Abstract
This study analyzed recent advances in third-wave psychotherapies applied to mental disorders. An integrative review of systematic reviews and meta-analyses published between 2022 and 2025 in indexed scientific literature was conducted. The findings indicate that Acceptance and Commitment Therapy, Dialectical Behavior Therapy, Behavioral Activation, Functional Analytic Psychotherapy, and Integrative Behavioral Couple Therapy show differential evidence depending on disorder and therapeutic process. It is concluded that process-based and transdiagnostic approaches constitute a relevant contribution to clinical mental health practice.
