Cognitive Behavioral Therapy

Core idea

CBT proposes that psychological distress is maintained less by events themselves than by the automatic thoughts and core beliefs we layer over them. Clients learn to catch a thought, examine the evidence, and choose a more balanced appraisal — and to act in ways that disconfirm catastrophic predictions. The model is collaborative, structured, time-limited (typically 12–20 sessions), and homework-driven.

Key concepts

Cognitive triangle

Thoughts ↔ feelings ↔ behaviors form a self-reinforcing loop.

Automatic thoughts

Fast, unbidden interpretations that color emotional response.

Core beliefs & schemas

Deeper rules about self, others, and the world (I'm unlovable, the world is dangerous).

Cognitive distortions

Predictable thinking errors — catastrophizing, mind-reading, all-or-nothing, etc.

Behavioral experiments

Real-world tests that gather evidence about a belief.

What a session looks like

1. 1
   Agenda set

   Therapist and client jointly choose 2–3 items for the hour.
2. 2
   Bridge from last week

   Homework review and mood check.
3. 3
   Main work

   Thought record, behavioral experiment, or skills practice on the chosen item.
4. 4
   New homework

   Specific, written, between-session task linked to today's work.
5. 5
   Summary & feedback

   Client summarizes takeaways; therapist asks what landed and what didn't.

Signature techniques

Evidence base

Most studied psychotherapy on record. Strong RCT support for depression, GAD, panic, social anxiety, OCD, PTSD, insomnia, and adjunctive use in psychosis and bipolar. Effect sizes typically moderate to large; durability strong when homework is completed.

Common pitfalls

• ▸Skipping the case formulation and jumping straight to techniques.
• ▸Treating Socratic questioning as cross-examination — debate triggers reactance.
• ▸Under-using behavioral experiments; over-relying on thought records.
• ▸Forgetting that low mood often needs activation before cognitive work lands.
