🧘 Cognitive Behavioral Therapy: An Evidence Hub

1. What CBT is

CBT modifies thoughts (cognitions) and behaviors to change emotional and physical outcomes. Standard course: 12-20 weekly sessions with structured homework (thought records, behavioral experiments, exposure).

• Cognitive restructuring — challenge automatic thoughts
• Behavioral activation — increase engagement despite mood
• Exposure therapy — face feared stimuli gradually
• ERP (exposure & response prevention) — first-line for OCD

2. CBT for depression

Meta-analyses consistently show CBT's effect size is comparable to antidepressant medication for mild-to-moderate depression, with lower relapse rates. Combined therapy often outperforms either alone.

3. CBT for anxiety disorders

Panic disorder, social anxiety, generalized anxiety, OCD, and PTSD all respond to CBT. Trauma-focused CBT and EMDR are recommended first-line for PTSD.

4. Other applications

• Adult ADHD — CBT complements medication by targeting executive function and time management
• Chronic pain — CBT reduces pain catastrophizing and preserves function
• Insomnia — CBT-I is now first-line, preferred over long-term sleep medication

5. Digital / online CBT (iCBT)

Self-guided or coach-supported iCBT has demonstrated efficacy comparable to face-to-face therapy for several conditions, at a fraction of the cost. Deployment barriers include engagement and dropout.

6. Limits and caveats

• Severe psychotic symptoms need medication first
• Therapeutic alliance matters — a poor therapist-client fit undermines efficacy
• Homework compliance is essential; low executive-function clients need scaffolding
