What is cognitive behavior therapy (CBT)? Is CBT effective?

In the last post I have mentioned social anxiety disorder(SAD) and CBT.

But what is SAD, what is CBT? Does CBT really effective? Does CBT effective than simple education?

Social anxiety disorder(SAD) is also called social phobia, characterized by a persistent and marked fear and avoidance of the social situations which he/she fears being evaluated negatively or being subjected to embarrassment.

SAD is believed to be the most prevalent of psychiatric conditions. But most individuals are never identified or obtain a treatment of social anxiety disorder.

Unlike transient worries and fears that do not lead to significant impairment of functioning. SAD always result in high levels of distress and significant functional impairment. Few friends, limited extracurricular activities, underachievement. SAD may also combined with depression, anxiety and substance use disorders.

There are two cognitive-behavioral treatments:
1. Individual CBT(I-CBT)
Participants in the individual therapy met for 1 h per week. Followed the same format and covered the same content as G CBT.
2. Cognitive behavioral group therapy(G-CBT)
Met for 2h each week and coled by 2 therapists, groups ranging in size from 4-6 patients. The treatments included psycho education, breathing retraining, cognitive restructuring, simulated and in Vivo exposure to phobic stimuli, social skills training.
3. Psycho educational supportive treatment(PST) which is the control group of CBT
A group of 4-6 persons met for 2h per week led by two therapists. Including discussions each session around various topics relevant to SAD, therapists offered support but not provide specific advice, teach skills, problem solving or assign exposure exercises.

Recovery rate of all kinds of CBT for adults
Check the result above. We evaluated these three CBT treatments to the SAD in adolescents.
The treatment effect was determined by calculating percentages of patients who no longer met criteria for social phobia at post treatment and follow up.
Results revealed that all three methods are effective to reduce the symptoms and distress and increase in social performance. G-CBT was more effective for follow up.
