The document outlines 12 principles of mental health nursing. These principles include accepting patients as they are, using self-understanding and consistent behavior to increase patient security, giving subtle reassurance, changing patient behavior through emotional experience rather than rational interpretation, avoiding increasing patient anxiety unnecessarily, objectively observing patients to understand their behavior, maintaining a realistic nurse-patient relationship, avoiding force as much as possible, caring for the patient's personhood rather than just their symptoms, explaining routines at the patient's level of understanding, and modifying procedures while keeping basic principles the same.
