Pros for this therapy
There is empirical evidence that CBT is effective for the treatment of a variety of problems, including mood, anxiety, personality, eating, substance abuse, and psychotic disorders. Treatment is often manualized, with specific technique-driven brief, direct, and time-limited treatments for specific psychological disorders. CBT is used in individual therapy as well as group settings, and the techniques are often adapted for self-help applications. Some clinicians and researchers are more cognitive oriented (e.g. cognitive restructuring), while others are more behaviorally oriented (in vivo exposure therapy). Other interventions combine both (e.g. imaginal exposure therapy).
Cons for this therapy
Cognitive behavioral therapy is unlikely to be effective in treating psychiatric problems caused solely by drug or alcohol abuse. It has been argued that the treatment of such patients should be directed at tackling their substance abuse problems (ideally aiming for complete abstinence) prior to the commencement of CBT.
