Cognitive-behavioral therapy has been found to be a useful strategy in the prevention of suicidal cognitions and suicidal behaviors. Cognitive-behavioral therapy has been proved to be effective for reducing the symptoms of various kinds of mental disorders that are directly associated with an increased risk of suicide such as depression, anxiety, and psychosis.  However, the treatments were found to be more effective for those patients who developed suicidal cognitions and behaviors independently rather than as a consequence of mental illness. This indicates that psychotherapy is more effective when it places focus on the elimination of suicidal cognitions and thoughts at the root.
