How psychiatric treatments can enhance psychological defense mechanisms

Psychological defense mechanisms are a powerful and often unappreciated force safeguarding mental health. Although rarely directed in this way, the most common forms of psychiatric treatment-psychotherapy and antidepressants-can enhance psychological defense mechanisms. Psychotherapy, through both specific and nonspecific factors, induces positive perspective shifts favoring positive cognitive distortions, including adaptive classical defense mechanisms and healthy attribution biases. Antidepressants, by altering very basic emotional information processing, such as facial expression recognition and emotional memories, also foster positive cognitive distortions. By shifting perceptions and thoughts in a positive direction, psychotherapy and antidepressants improve the capacity to dissociate from negative emotional stimuli.
