A pattern by which an individual attempts to make up for a perceived physical or psychological deficiency by excelling in another area. It channels tension into an area of strength.

Hospital Example: A nursing student who struggles heavily with the physical dexterity required for starting IVs (perceived weakness) compensates by studying relentlessly to achieve the highest possible grade on the complex pharmacology written exam (area of strength).

A mechanism by which tension or anxiety is reduced by replacing an unattainable, highly desired goal or object with one that is attainable and acceptable.

Hospital Example: A surgical resident who develops a fine motor tremor and realizes they can no longer become a neurosurgeon (unattainable goal) decides to substitute that goal and becomes a highly successful internal medicine diagnostician instead.

The healthiest of all mechanisms. It involves the channelization of socially unacceptable urges or aggressive desires into productive, socially acceptable, and even admirable actions.

Hospital Example: A patient who survives a traumatic amputation and struggles with intense, explosive anger regarding the accident channels that aggressive energy into starting a non-profit organization that fiercely advocates for disability rights and hospital safety.

An individual justifies their own socially unacceptable behaviors, failures, or feelings by formulating logical-sounding, plausible excuses to avoid accepting the true underlying reason.

Hospital Example: A staff nurse who makes a medication error (which was caught in time) avoids taking personal responsibility by rationalizing, "The pharmacy sent the meds up late, the ward was understaffed, and the lights are too dim in the med room—anyone would have made that mistake."

The primary ego defense. It is the unconscious process of pushing painful, threatening, or traumatic memories and thoughts out of conscious awareness entirely. (Unconscious forgetfulness).

Hospital Example: A patient who was admitted to the ICU for severe ARDS and endured a highly traumatic, painful prolonged intubation has absolutely no conscious memory of the horrific pain or anxiety they experienced during those three weeks.

Through this process, an individual attempts to increase their own self-worth and reduce anxiety by unconsciously acquiring the attributes, characteristics, or mannerisms of a highly admired person.

Hospital Example: A newly graduated nurse, feeling extremely anxious and insecure, subconsciously begins to mimic the exact tone of voice, calm body language, and clinical phrases of their veteran preceptor when responding to emergency codes.

The image, feelings, and expectations regarding one person are unconsciously identified with or transferred onto another person (often a healthcare provider).

Hospital Example: An elderly female patient becomes unreasonably demanding, emotionally attached, and affectionate toward a young male nurse because he unconsciously reminds her of her own son who never visits her.

An attempt to avoid expressing actual emotions associated with a stressful situation by using cold logic, heavy reasoning, and statistical analysis.

Hospital Example: A physician diagnosed with terminal pancreatic cancer completely avoids processing the grief and fear of dying by spending 10 hours a day analyzing medical journals, discussing the statistics of experimental chemo-trials, and critiquing cellular biology with their oncologist.

Internalizing the beliefs, values, or characteristics of another person or group so deeply that they become a part of the individual's own core personality.

Hospital Example: A medical student absorbs the strict, perfectionist moral code of their attending surgeon regarding sterile technique, to the point where the student feels intense, visceral guilt if they ever see anyone break sterility, viewing it as a personal moral failure.

Unlike repression (which is unconscious), suppression is the conscious, deliberate forcing of unpleasant, anxiety-producing thoughts out of the conscious mind. It can become negative if it leads to permanent avoidance of a problem.

Hospital Example: An ER physician whose spouse just asked for a divorce consciously decides, "I am not going to think about my marriage falling apart right now," and pushes it out of their mind to focus entirely on treating a trauma patient.

An unconscious emotional feeling (usually anger or frustration) is transferred from its actual, threatening source to a safer, less threatening substitute target.

Hospital Example: A surgeon is severely reprimanded and humiliated by the Chief of Medicine. Unable to yell at the Chief, the surgeon goes into the OR and violently yells at the scrub nurse for handing them the wrong retractor.

Placing blame for one's own unacceptable feelings, thoughts, or mistakes onto someone else. It is attributing one's own inner darkness to the outside world.

Hospital Example: A nurse who secretly harbors deep resentment and dislike for a particular demanding patient constantly complains to the charge nurse, claiming, "That patient completely hates me and has a terrible attitude toward me."

Retreating into a dream world or imagination when reality is too painful, demanding, or unfulfilling. It allows the person to achieve in their mind what they cannot in reality.

Hospital Example: A severely burned patient facing months of painful rehabilitation spends most of the day staring at the wall, deeply fantasizing about being a famous athlete running on a beach, completely refusing to participate in physical therapy.

The refusal to acknowledge the existence of a real situation, condition, or the feelings associated with it. It is closing one's eyes to a threatening reality.

Hospital Example: A patient who has just been diagnosed with terminal Stage IV lung cancer continues to talk cheerfully about their plans to travel the world next year, ignoring all palliative care discussions and refusing to believe the scans.

Retreating to an earlier, less demanding developmental stage of behavior or maturity when faced with severe stress or anxiety.

Hospital Example: A 6-year-old child who has been fully potty-trained for years begins to wet the bed, insist on drinking from a bottle, and sucks their thumb immediately after being admitted to the pediatric oncology ward for leukemia treatment.

Preventing unacceptable or undesirable thoughts/behaviors from being expressed by exaggerating opposite thoughts or types of behaviors.

Hospital Example: A nursing manager who deeply dislikes a new, young, highly competent graduate nurse goes out of their way to act overly sweet, excessively praising and showering the graduate with gifts in front of other staff members.

Symbolically negating or "canceling out" a previous unacceptable action, thought, or behavior in order to relieve intense guilt.

Hospital Example: An attending physician who loses their temper and aggressively yells at a medical student during clinical rounds feels immense guilt. Later that day, they buy the student an expensive medical textbook and coffee to "erase" the bad behavior.

The unconscious transformation of severe psychological anxiety into a physical symptom with no organic physiological cause. The physical symptom allows the person to avoid the stressful situation.

Hospital Example: A nursing student, absolutely terrified of giving their first intramuscular injection during a critical clinical exam, suddenly develops complete, unexplained paralysis of their dominant right arm the morning of the test.

Separating a thought or memory from the feeling, tone, or emotion associated with it. The memory remains, but the emotional pain is completely stripped away.

Hospital Example: An ER nurse describes the horrific, bloody details of a massive multi-car casualty trauma event to their colleagues with a completely flat, monotone affect, showing zero emotional response to the tragedy.

Dealing with emotional conflict or stress by resorting to observable, often disruptive or aggressive behavior rather than reflection, feeling, or talking.

Hospital Example: A psychiatric patient feeling deeply abandoned because their favorite therapist is going on a two-week vacation responds by throwing a chair through a window on the ward instead of expressing their sadness verbally.

Splitting off a group of thoughts or activities from main conscious awareness; disconnecting from one's own identity, memory, or environment during a traumatic event to protect the mind.

Hospital Example: During a highly invasive, painful, and traumatic emergency bedside procedure without adequate sedation, the patient disconnects from reality and describes feeling as though they were floating on the ceiling, watching the doctors work on a stranger's body.
