CBT — Cognitive Behavioral Therapy — is the most studied method of psychotherapy. How it works, what problems it helps with, and how it differs from other approaches.
"The most studied psychotherapy" is not a marketing slogan. Cognitive Behavioral Therapy has more randomized controlled trials than any other psychotherapeutic approach. This doesn't mean it is universal — but it does mean we know when it works and when it doesn't.
Two roots. First — behavioral therapy of the 1950s-60s: Skinner, Wolpe, desensitization, operant conditioning. Second — the cognitive revolution of the 1970s: Aaron Beck (cognitive therapy for depression) and Albert Ellis (Rational Emotive Behavior Therapy). The merger of the two lines gave us "CBT."
Key idea: events don't cause emotions — it is how we interpret them that does. Situation → thought (interpretation) → emotion → behavior. This is the CBT triangle.
Example: a friend is late. Thought A: "I'm not important to him" → hurt, distancing. Thought B: "Probably traffic" → mild irritation, waiting. Same situation — different reactions. Because different thoughts.
Strongest evidence base for: depression, panic disorder, GAD, OCD, social anxiety, PTSD, eating disorders, specific phobias, insomnia, chronic pain. Moderate evidence for: bipolar disorder, psychosis, personality disorders (with adaptations).
Structured: each session has an agenda, homework, progress measurement. Short-term: 12-20 sessions for most disorders. Present-focused: working with current problems, not exclusively the past. Teaches skills: the person leaves with tools, not dependence on the therapist.
