Approaches to Talking Therapy: CBT, ACT, DBT, and Person-Centred Counselling Compared

Why the Type of Therapy Can Matter

Talking therapies are not one-size-fits-all. While all reputable approaches share a commitment to a safe, confidential relationship between client and therapist, they differ substantially in how sessions are structured, what they ask of the client, and what they aim to change. Understanding these differences can make it easier to ask informed questions when seeking support — or to support someone else in doing so. See our thoughtful approach to difficult mental health conversations for practical advice on bringing up therapy with someone you're concerned about.

The four approaches covered here — Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), Dialectical Behaviour Therapy (DBT), and Person-Centred Counselling — are among the most commonly encountered in the US. Each has a distinct theoretical foundation, a different style of working, and a different evidence base.

Cognitive Behavioural Therapy (CBT)

CBT is a structured, time-limited approach based on the principle that thoughts, feelings, and behaviours are interconnected. By identifying and examining unhelpful thinking patterns — sometimes called cognitive distortions — and gradually changing associated behaviours, people can shift how they feel. Sessions typically involve homework between appointments, such as keeping thought records or practising specific behaviours.

CBT has one of the largest evidence bases in psychotherapy research, with well-documented support for conditions including generalised anxiety, depression, phobias, OCD, and PTSD. Its structured format suits people who prefer a goal-oriented, skills-focused approach. It is less suited to those looking primarily for open-ended exploration or who find structured tasks burdensome.

Acceptance and Commitment Therapy (ACT)

ACT (pronounced as one word, like "act") grew from the CBT tradition but takes a different tack. Rather than challenging the content of difficult thoughts, ACT teaches people to relate differently to them — observing thoughts without being governed by them, a process called cognitive defusion. Alongside this, ACT emphasises identifying personal values and committing to actions aligned with those values, even in the presence of discomfort.

ACT incorporates mindfulness practices and is used for anxiety, depression, chronic pain, and stress. It tends to appeal to people who have found thought-challenging approaches frustrating, or who want a framework for living more intentionally rather than simply reducing symptoms.

Dialectical Behaviour Therapy (DBT)

DBT was originally developed for people experiencing chronic suicidal ideation and borderline personality disorder (BPD), but is now applied across a range of presentations involving intense emotional experiences and interpersonal difficulties. The word dialectical refers to the balancing of opposites — most centrally, the balance between acceptance and change.

Standard DBT is intensive: it typically combines individual therapy with a skills training group covering four modules — mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. Adapted, shorter versions exist for settings where full DBT is not available. DBT requires significant commitment and is best suited to contexts where emotional intensity or relationship instability is a central concern.

Person-Centred Counselling

Developed by psychologist Carl Rogers, person-centred counselling (also called Rogerian therapy or client-centred therapy) places the therapeutic relationship itself at the heart of change. The therapist provides three core conditions: empathy, unconditional positive regard, and congruence (authenticity). Rather than directing the client toward specific goals or skills, the therapist trusts the client's own capacity for growth when offered the right relational conditions.

Sessions are non-directive and open-ended, making this approach well suited to people processing grief, identity questions, life transitions, or any experience they want to explore without a fixed agenda. It is less prescriptive than CBT or DBT, and the evidence base, while meaningful, is different in character — focused more on relational outcomes than symptom checklists.
