________ are highly successful in helping people cope with pain, chronic fatigue syndrome, headaches, or irritable bowel syndrome.

A) Systematic desensitization and exposure techniques
B) Cognitive and behavior therapies
C) Psychodynamic and humanist therapies
D) Family intervention therapy and behavioral skills training

Cognitive and behavior therapies have been shown to be highly effective in helping people cope with pain, chronic fatigue syndrome, headaches, or irritable bowel syndrome. These therapies focus on changing negative thoughts and behaviors related to pain or illness, and teaching coping skills and relaxation techniques. Systematic desensitization and exposure techniques are more commonly used in treating anxiety disorders, while psychodynamic and humanistic therapies may be helpful for some individuals but have not been shown to be consistently effective for these particular conditions. Family intervention therapy and behavioral skills training may be helpful in some cases, but are not typically used as standalone treatments for these conditions.
