There are three main types of treatment for psychological disorders: psychotherapy which includes insight and behavior therapies, biomedical therapies which target biological functions, and psychopharmacotherapy which uses medication. Around 15% of the US population seeks treatment annually, most commonly for anxiety and depression. Treatment is provided by psychologists, psychiatrists, social workers, nurses, and counselors using approaches like psychoanalysis, cognitive behavioral therapy, systematic desensitization, and medication. Current issues include managed care, blending treatment methods, and cultural sensitivity.
