A practical comparison of CBT, ACT, DBT, EMDR and Schema Therapy—when to use each, and why.

Mental health practitioners have access to a wide range of evidence-based therapeutic approaches, each designed to address different client needs, presenting concerns, and treatment goals. This article compares several widely recognised models, including Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), Dialectical Behaviour Therapy (DBT), Eye Movement Desensitisation and Reprocessing (EMDR), and Schema Therapy. It explains the theoretical foundations, core techniques, strengths, and limitations of each approach while identifying the types of presentations for which they are commonly recommended. Readers will also explore factors influencing treatment selection, including symptom severity, client preferences, comorbidities, trauma history, and therapeutic readiness. Rather than promoting one model over another, the article demonstrates how clinicians can select and integrate interventions based on current evidence, professional judgement, and individual client circumstances. It serves as a practical reference for practitioners seeking to strengthen clinical reasoning, expand therapeutic knowledge, and deliver personalised, evidence-informed mental health care.
