I now have all the content needed from Kaplan & Sadock's Comprehensive Textbook of Psychiatry. Let me compose the detailed answer.

Defence Mechanisms - A Detailed Classification

Defence mechanisms are unconscious psychological processes used by the ego to manage internal conflicts between drives, superego demands, and external reality. Anna Freud systematized them in The Ego and the Mechanisms of Defence (1936), and they are classified here into four major levels based on maturity and the psychopathology with which they are associated.

Overview and Conceptual Basis

Defence mechanisms:

Arise early in development to help the ego mediate id pressures and external reality demands
Each libidinal phase evokes characteristic defences (e.g., introjection/denial with the oral stage; reaction formation with the anal stage)
Are classified by: (1) developmental level, (2) associated psychopathology, (3) whether simple or composite mechanisms
Are NOT limited to pathology - everyone uses a repertoire, though the predominance of immature mechanisms signals pathology

1. Narcissistic/Psychotic Defences

"Usually found as part of a psychotic process, but may also occur in young children and adult dreams or fantasies. They share the common note of avoiding, negating, or distorting reality."

Kaplan & Sadock's Comprehensive Textbook of Psychiatry

These are the most primitive, operating by altering or rejecting perception of external reality.

Mechanism	Definition	Example
Projection (psychotic level)	Perceiving and reacting to unacceptable inner impulses as though they come from outside the self. At the psychotic level this takes the form of frank persecutory delusions; impulses may derive from id or superego.	A patient who harbours violent impulses develops a delusion that neighbours are plotting to kill him. Hallucinated recriminations ("You are worthless") represent projected superego attacks.
Denial (psychotic level)	Seeing, but refusing to acknowledge what one sees or hears - affects perception of external reality more than internal reality. The denied reality may be replaced by a fantasy or delusion.	A patient whose spouse died insists the spouse is still alive, constructing an elaborate belief system to sustain this. A person with complete blindness (anosognosia in Anton syndrome) insists they can see.
Distortion	Grossly reshaping external reality to suit inner needs - unrealistic megalomanic beliefs, hallucinations, wish-fulfilling delusions, sustained feelings of delusional grandiosity, superiority, or entitlement.	A patient with schizophrenia believes he is Jesus Christ and his mission is to save humanity. Grandiose delusions in mania ("I have discovered the cure for all disease").

2. Immature Defences

"Fairly common in preadolescent years and in adult character disorders. Often mobilized by anxieties related to intimacy or its loss. They moderate with improvement in interpersonal relationships or increased personal maturity."

Kaplan & Sadock's Comprehensive Textbook of Psychiatry

These are seen in personality disorders, adolescence, and under severe stress.

Mechanism	Definition	Example
Acting Out	Direct expression of an unconscious wish or impulse in action, to avoid being conscious of the accompanying affect. The fantasy is "lived out" impulsively, gratifying the impulse over the prohibition against it.	A patient with borderline personality disorder, enraged at feeling abandoned by the therapist, goes on a spending binge or engages in self-cutting rather than tolerating the feeling.
Blocking	Temporary inhibition of affects, thinking, or impulses. Close to repression but with a component of tension arising from inhibition.	An otherwise articulate student goes completely blank mid-presentation when anxiety about a related repressed conflict mounts.
Hypochondriasis	Transformation of reproach toward others (arising from bereavement, loneliness, or unacceptable aggression) into self-reproach expressed as somatic complaints of pain and illness. Responsibility is avoided, guilt is circumvented, and instinctual impulses are warded off.	A bereaved widow redirects her anger at her deceased husband into chronic back pain and multiple medical consultations, gaining "sick role" exemption from responsibilities.
Introjection (defensive)	Internalising characteristics of a feared or loved object to avoid anxiety. Internalising a feared object's aggression puts it under one's own control (classic example: "identification with the aggressor").	A child who is physically abused by a parent internalises the abuser's cruelty and begins bullying classmates - "identification with the aggressor." A hostage who begins adopting the captor's worldview (Stockholm syndrome).
Passive-Aggressive Behaviour	Aggression toward an object expressed indirectly and ineffectively through passivity, masochism, and turning against the self.	An employee who is angry at their boss consistently misses deadlines, "forgets" assigned tasks, or works slowly - never directly expressing anger.
Projection (non-psychotic level)	Attributing one's own unacknowledged feelings to others; includes severe prejudice, rejection of intimacy through suspiciousness, hypervigilance to external danger, "injustice collecting." At higher function, misattributing motives or intentions of others.	A person who has unconscious hostility toward a colleague repeatedly interprets neutral remarks as attacks. A homophobic individual who has unacknowledged same-sex attraction projects it as "all men are attracted to me."
Regression	Return to a previous stage of development or functioning to avoid anxieties or hostilities involved in later stages. Based on return to earlier points of fixation.	An adult hospitalised for surgery begins crying and demanding constant reassurance from nurses in a childlike manner. A toilet-trained child begins bedwetting when a new sibling is born.
Schizoid Fantasy	Using fantasy and autistic retreat for conflict resolution and gratification.	A socially isolated young man avoids real relationships and spends all his time absorbed in elaborate fantasy worlds, resolving his conflicts through imagined victories and connections.
Somatization	Defensive conversion of psychic derivatives into bodily symptoms. Regression to earlier somatic forms of response.	A student who cannot consciously acknowledge anxiety about an exam develops recurrent vomiting and abdominal pain before every examination.
Splitting	Inability to integrate the positive and negative qualities of oneself or others into a coherent whole - people are seen as all-good or all-bad (a hallmark of borderline personality disorder).	A patient idealises the ward nurse as "the only one who understands me" and simultaneously devalues the treating doctor as "completely useless and cruel." These attitudes reverse abruptly when frustrated.

3. Neurotic Defences

"Common in apparently normal and healthy individuals as well as neurotic disorders. Function in the alleviation of distressing affects. Depending on circumstances, they can have an adaptive or socially acceptable aspect."

Kaplan & Sadock's Comprehensive Textbook of Psychiatry

These are the workhorses of neurosis - OCD, phobias, hysteria.

Mechanism	Definition	Example
Controlling	Excessive attempt to manage or regulate events or objects in the environment to minimise anxiety and solve internal conflicts.	A person with OCD arranges their desk in an exact order, becoming extremely distressed if anything is moved, as a way of managing underlying anxiety.
Displacement	Purposeful unconscious shifting of impulses and/or affective investment from one object to another to solve a conflict. The instinctual nature of the impulse and its aim remain unchanged; only the object is changed.	A man who is furious at his boss comes home and shouts at his child. A patient with a phobia of dogs actually fears the aggression impulses represented by the animal.
Dissociation	Temporary but drastic modification of character or sense of personal identity to avoid emotional distress; includes fugue states and hysterical conversion reactions.	A person with PTSD experiences emotional numbing and feels detached from their body (depersonalisation) when recounting trauma. A patient with dissociative identity disorder switches "alters" under stress.
Externalization	General tendency to perceive in the external world components of one's own personality (impulses, conflicts, moods, attitudes). Broader than projection - does not require specific introjects.	A student who feels inferior constantly attributes their failures to teachers being unfair or circumstances being against them.
Inhibition	Unconsciously determined limitation or renunciation of specific ego functions to avoid anxiety arising out of conflict with instincts, superego, or environment.	A gifted writer with unconscious conflicts about expressing aggression finds he is completely unable to write. Sexual inhibition in someone whose sexuality triggers guilt.
Intellectualization	Controlling affects and impulses by thinking about them instead of experiencing them. Systematic excess of thinking, deprived of affect, to defend against anxiety from unacceptable impulses.	A medical student who has just been diagnosed with a serious illness begins reading medical journals and discussing statistics and prognosis with clinical detachment, avoiding the emotional impact.
Isolation of Affect	Intrapsychic splitting of affect from content - repression of either the idea or its affect, or displacement of affect to a substitute.	A trauma survivor describes in precise, unemotional detail the events of their assault, without any apparent distress - the traumatic memory is retained but its affect is stripped away.
Rationalization	Justification of attitudes, beliefs, or behaviour that might otherwise be unacceptable, by incorrect application of justifying reasons or invention of a convincing falsehood.	A student who failed an exam because they didn't study tells themselves and others "the paper was unfairly set" or "the teacher doesn't like me." A person who acts selfishly invents altruistic motives for having done so.
Reaction Formation	Management of unacceptable impulses by permitting their expression in antithetical (opposite) form. Where conflict is persistent, this becomes a character trait.	Excessive, demonstrative care shown toward a sibling who is unconsciously resented and hated. A person with strong sadistic impulses becomes an advocate for animal rights. A person with strong sexual impulses becomes a prominent anti-pornography campaigner.
Repression	Expelling and withholding from consciousness an idea or feeling. Primary repression - curbing ideas before they reach consciousness. Secondary repression - excluding from awareness what was once experienced consciously. Often accompanied by highly symbolic behaviour.	A person has no memory whatsoever of a period of childhood sexual abuse, yet becomes inexplicably anxious in contexts that symbolically echo the abusive situation.
Sexualization	Endowing an object or function with sexual significance it did not previously have, to ward off anxieties connected with prohibited impulses.	A person transforms anxiety-provoking aggressive urges into sadomasochistic sexual fantasies that are ego-syntonic, thus making the anxiety manageable.

4. Mature Defences

"Healthy and adaptive throughout the life cycle. Socially adaptive and useful in the integration of personal needs and motives, social demands, and interpersonal relations. They can underlie seemingly admirable and virtuous patterns of behaviour."

Kaplan & Sadock's Comprehensive Textbook of Psychiatry

These were elaborated especially by George Vaillant (data cited in Kaplan & Sadock's, attributed to Vaillant GE, Adaptation to Life, 1977).

Mechanism	Definition	Example
Altruism	Vicarious but constructive and instinctually gratifying service to others. Distinguished from altruistic surrender, which involves masochistic self-sacrifice without true gratification.	A formerly drug-addicted doctor becomes a dedicated addiction medicine specialist, channelling their own struggles into genuine service that also provides deep personal satisfaction.
Anticipation	Realistic anticipation of or planning for future inner discomfort - includes concerned planning and worrying about possible outcomes - but in a way that prepares rather than paralyses.	A student who knows they become anxious in exams prepares months in advance and rehearses relaxation strategies, reducing the actual impact of the stress.
Asceticism	Elimination of directly pleasurable affects attributable to an experience. The moral element sets values on specific pleasures; gratification is derived from the renunciation itself.	A monk voluntarily forgoes pleasures (food, sex, comfort) and derives deep fulfilment from this discipline, channelling drive energy into spiritual meaning.
Humor	Overt expression of feelings without personal discomfort or immobilisation, and without unpleasant effect on others. Allows one to bear - yet focus on - what is too terrible to be borne. Contrasted with wit (which displaces away from the affect).	A patient terminally ill with cancer makes witty, self-aware jokes about their situation that acknowledge the reality without catastrophising, while also enabling others around them to cope.
Sublimation	Gratification of an impulse whose goal is retained but whose aim or object is changed from a socially objectionable one to a socially valued one. Aggressive impulses are channelled; feelings are acknowledged, modified, and directed - not dammed up or diverted. Modest instinctual satisfaction still results.	A person with strong aggressive drives becomes a surgeon or a professional boxer. A person with intense sexual drives becomes a sculptor or painter of nudes.
Suppression	The conscious or semiconscious decision to postpone attention to a conscious impulse or conflict. Unlike repression, it is deliberate and the material remains available to consciousness.	A doctor who receives distressing personal news in the morning consciously decides to set it aside until after a critical surgery that afternoon, then allows themselves to process it in the evening.

Key Distinctions Worth Knowing

Repression vs. Suppression: Repression is unconscious (material is expelled from awareness); suppression is conscious (deliberate postponement, material accessible).
Projection vs. Distortion: Projection attributes internal states to others; distortion reshapes the whole perception of external reality.
Intellectualization vs. Rationalization: Intellectualization replaces affect with thinking; rationalization invents logical justifications for unacceptable behaviour.
Isolation vs. Repression: Isolation strips the affect from the idea (the idea remains conscious, the feeling is lost); repression removes the whole idea from consciousness.
Sublimation vs. Reaction Formation: Sublimation channels the impulse into a new, valued outlet (instinct still achieves expression); reaction formation expresses the opposite of the impulse (the original impulse is denied).
Denial (psychotic) vs. Repression: Denial affects external reality (refusing to perceive); repression affects internal reality (expelling ideas or feelings from awareness).
