Alternative DSM-5 Model for Personality Disorders (AMPD)

Part of the Alternative DSM-5 Model and Conditions for Further Study chapter reference — index: 33-alternative-dsm-5-model-and-conditions-for-further-study.md

Summarized and paraphrased from DSM-5-TR (American Psychiatric Association, 2022). This file is for orientation and education; verify exact criteria wording, codes, and recording procedures against the official DSM-5-TR before any formal clinical, legal, insurance, or research use.

What the AMPD is and why it exists

The AMPD was developed as a dimensional alternative to the Section II categorical personality disorder classification. The Section II approach has well-recognized limitations: symptom patterns meeting criteria for one personality disorder frequently meet criteria for others, and "other specified or unspecified personality disorder" is often the correct but uninformative diagnosis. The AMPD addresses this by defining personality disorder in terms of two determinations:

1. Criterion A — the level of impairment in personality (self and interpersonal) functioning, rated with the Level of Personality Functioning Scale (LPFS).
2. Criterion B — pathological personality traits, organized into five broad domains containing 25 trait facets.

Six specific personality disorder types are defined in the model (antisocial, avoidant, borderline, narcissistic, obsessive-compulsive, and schizotypal), plus Personality Disorder–Trait Specified (PD-TS) for presentations that do not match a specific type. Both models coexisting in DSM-5 reflects the APA's decision to preserve continuity with clinical practice while introducing a dimensional alternative.

General Criteria for Personality Disorder (criteria A–G)

A personality disorder in the AMPD requires all of the following:

• Criterion A: Moderate or greater impairment in personality (self/interpersonal) functioning.
• Criterion B: One or more pathological personality traits.
• Criterion C: The impairments in personality functioning and trait expression are relatively inflexible and pervasive across a broad range of personal and social situations.
• Criterion D: The impairments and trait expression are relatively stable across time, with onsets that can be traced back to at least adolescence or early adulthood.
• Criterion E: The impairments and trait expression are not better explained by another mental disorder.
• Criterion F: The impairments and trait expression are not solely attributable to the physiological effects of a substance or another medical condition (e.g., severe head trauma).
• Criterion G: The impairments and trait expression are not better understood as normal for the individual's developmental stage or sociocultural environment.

All six specific personality disorders and PD-TS meet these general criteria by definition.

Criterion A — Level of Personality Functioning Scale (LPFS)

Impairment in self and interpersonal functioning is the core of personality psychopathology. Four elements are assessed:

Area	Elements
Self	Identity — experience of oneself as unique, with clear self–other boundaries; stability of self-esteem and accuracy of self-appraisal; capacity to experience and regulate a range of emotions
Self	Self-direction — pursuit of coherent and meaningful short-term and life goals; use of constructive, prosocial internal standards; ability to self-reflect productively
Interpersonal	Empathy — comprehension and appreciation of others' experiences and motivations; tolerance of differing perspectives; understanding of the effects of one's own behavior on others
Interpersonal	Intimacy — depth and duration of connection with others; desire and capacity for closeness; mutuality of regard in interpersonal behavior

The LPFS uses these elements to rate five levels of impairment: 0 = little or no impairment (healthy, adaptive functioning); 1 = some impairment; 2 = moderate impairment; 3 = severe impairment; 4 = extreme impairment. Moderate or greater impairment (level 2+) is required for any personality disorder diagnosis — a threshold set empirically to maximize accurate identification of personality disorder pathology. Impairment severity also predicts whether an individual has more than one personality disorder or one of the more typically severe disorders. The LPFS can also be used as a global indicator of personality functioning without a disorder diagnosis, and the level can be recorded as a specifier.

Paraphrased anchor points for each level (identity / self-direction / empathy / intimacy):

• Level 0: A unique, coherent sense of self with appropriate boundaries; realistic goals pursued with appropriate standards; accurate understanding of others and of one's effect on them; multiple satisfying, enduring, reciprocal relationships.
• Level 1: Generally intact self but some decreased clarity of boundaries under strong emotion, fluctuating self-esteem; some difficulties with overly perfectionistic or conflict-avoidant goal pursuit; somewhat compromised ability to appreciate others' experiences; relationships established but with some limits on depth and satisfaction.
• Level 2: Identity depends excessively on others with compromised boundaries and vulnerable self-esteem tied to external approval; goals pursued largely for external approval, with standards either unreasonably high or too low; empathy impaired — hyperattuned to others only as relevant to self, generally unaware of one's effect on others; relationships largely superficial, intimacy centered on self-regulatory needs, limited reciprocity.
• Level 3: Weak or rigid sense of self (emptiness, poor boundaries, fragile self-esteem easily influenced by events); unclear or contradictory standards, life experienced as meaningless or dangerous; markedly limited ability to understand others' perspectives; relationships based on fear of abandonment or expectations of abuse, with little mutuality.
• Level 4: Sense of self and agency virtually absent or organized around perceived external persecution; goals unrealistic or incoherent, internal standards virtually lacking; pronounced inability to consider others' experience, attention to others almost absent; relationships conceptualized almost entirely in terms of comfort or harm, with little or no reciprocity.

Criterion B — Pathological personality traits

A personality trait is a tendency to feel, perceive, behave, and think in relatively consistent ways across time and situations. Traits exist on spectra with two opposing poles; the maladaptive poles are the focus of the model, while the opposite poles are healthy, adaptive variants that can mitigate the effects of mental disorders and facilitate coping and recovery. Traits are more stable than symptoms, but they are not immutable and do change across the life span. Broad trait dimensions are called domains; specific trait dimensions are called facets. The five domains are maladaptive variants of the "Big Five" (Five Factor Model) and resemble the Personality Psychopathology Five (PSY-5).

Domain (polar opposite)	Facets
Negative Affectivity (vs. Emotional Stability)	Emotional lability; anxiousness; separation insecurity; submissiveness; hostility; perseveration (depressivity, suspiciousness, and restricted affectivity also load here but are defined under Detachment)
Detachment (vs. Extraversion)	Withdrawal; intimacy avoidance; anhedonia; depressivity; restricted affectivity; suspiciousness
Antagonism (vs. Agreeableness)	Manipulativeness; deceitfulness; grandiosity; attention seeking; callousness (hostility also loads here)
Disinhibition (vs. Conscientiousness)	Irresponsibility; impulsivity; distractibility; risk taking; (lack of) rigid perfectionism
Psychoticism (vs. Lucidity)	Unusual beliefs and experiences; eccentricity; cognitive and perceptual dysregulation

In total the model contains 25 trait facets. The B criteria of the six specific personality disorders use subsets of these facets, selected on the basis of meta-analytic reviews and empirical data relating traits to the DSM-IV personality disorder diagnoses. The trait model is operationalized in the Personality Inventory for DSM-5 (PID-5), which has a self-report form (completed by the patient) and an informant-report form (completed by someone who knows the patient well, e.g., a spouse). A detailed assessment collects both perspectives on all 25 facets; when only a general portrait is needed, assessment at the five-domain level is an acceptable option. A trait is considered elevated — and able to contribute to Criterion B — when formal psychometric testing and/or interview data support clinical judgment of elevation.

The six specific personality disorders (criteria A and B, summarized)

All require moderate or greater impairment in personality functioning, manifested by characteristic difficulties in two or more of the four areas (identity, self-direction, empathy, intimacy), plus the required pathological traits. Trait and level-of-functioning specifiers can be added to record additional personality features not required for the diagnosis.

Disorder	Criterion A: impairment in 2+ of 4 areas	Criterion B: required pathological traits
Antisocial	Egocentrism; goals set for personal gratification without prosocial standards; lack of concern for others' feelings/suffering and lack of remorse; intimacy via exploitation, deceit, coercion, dominance	6 or more of 7 traits: manipulativeness, callousness, deceitfulness, hostility (Antagonism); risk taking, impulsivity, irresponsibility (Disinhibition). Individual is at least 18 years of age. Specify if: with psychopathic features
Avoidant	Low self-esteem with self-appraisal as socially inept or inferior; unrealistic standards leading to reluctance to take risks; preoccupation with and sensitivity to criticism with distorted negative inferences about others; reluctance to get involved unless certain of being liked	3 or more of 4 traits, one of which must be anxiousness: anxiousness (Negative Affectivity); withdrawal, anhedonia, intimacy avoidance (Detachment)
Borderline	Impoverished, poorly developed, or unstable self-image, chronic emptiness, dissociative states under stress; instability in goals/values; compromised empathy with interpersonal hypersensitivity; intense, unstable, conflicted relationships with fear of abandonment and idealization/devaluation	4 or more of 7 traits, at least one of which must be impulsivity, risk taking, or hostility: emotional lability, anxiousness, separation insecurity, depressivity (Negative Affectivity); impulsivity, risk taking (Disinhibition); hostility (Antagonism)
Narcissistic	Excessive reference to others for self-definition and self-esteem regulation; exaggerated (inflated, deflated, or vacillating) self-appraisal; goals set for approval with standards too high or too low; impaired ability to recognize others' feelings; relationships largely superficial, serving self-esteem regulation	Both of: grandiosity (Antagonism) and attention seeking (Antagonism)
Obsessive-Compulsive	Sense of self derived predominantly from work/productivity with constricted emotion; rigid, unreasonably high internal standards impeding task completion; difficulty appreciating others' ideas/feelings; relationships seen as secondary to work, affected by rigidity and stubbornness	3 or more of 4 traits, one of which must be rigid perfectionism: rigid perfectionism (extreme Conscientiousness, the opposite pole of Disinhibition); perseveration (Negative Affectivity); intimacy avoidance, restricted affectivity (Detachment)
Schizotypal	Confused self–other boundaries and distorted self-concept; unrealistic or incoherent goals without clear internal standards; pronounced difficulty understanding one's effect on others; marked impairment in close relationships with mistrust and anxiety	4 or more of 6 traits: cognitive and perceptual dysregulation, unusual beliefs and experiences, eccentricity (Psychoticism); restricted affectivity, withdrawal, suspiciousness (Detachment)

Specifiers (all six): trait specifiers record additional personality features (e.g., Negative Affectivity traits such as anxiousness for antisocial, obsessive-compulsive, and schizotypal types; Psychoticism traits such as cognitive and perceptual dysregulation for borderline; Antagonism traits such as manipulativeness, deceitfulness, and callousness for narcissistic — the "malignant narcissism" pattern; Negative Affectivity traits for "vulnerable" narcissistic presentations), and the level of personality functioning can always be specified. For antisocial personality disorder, the specifier "with psychopathic features" marks the variant ("primary" psychopathy) characterized by low anxiousness and low withdrawal and high attention seeking, giving a bold, stress-immune interpersonal style that can mask maladaptive behaviors.

Personality Disorder–Trait Specified (PD-TS)

• Criterion A: Moderate or greater impairment in personality functioning, with difficulties in two or more of the four areas (identity, self-direction, empathy, intimacy).
• Criterion B: One or more pathological personality trait domains OR specific trait facets within domains, considering all five domains (Negative Affectivity, Detachment, Antagonism, Disinhibition, Psychoticism).
• PD-TS is used when a personality disorder is considered present but the presentation does not match one of the six specific types — for example, a subthreshold presentation (insufficient A or B criteria for a type), a mix of features of several types, or an atypical pattern. Subtypes are unnecessary because the dimensional trait model itself describes the profile; the recorded trait combination constitutes the specifier (e.g., two individuals both characterized by emotional lability, hostility, and depressivity may differ in that one also shows callousness).
• The Section II diagnoses of paranoid, schizoid, histrionic, and dependent personality disorders are represented in the AMPD by PD-TS: they are defined by moderate or greater impairment in personality functioning plus the relevant pathological trait combinations.

How the AMPD is used in practice

Diagnostic thresholds (requiring two of four A-criteria areas; the B-criterion trait counts) were set empirically to preserve continuity with DSM-IV prevalence, minimize overlap between personality disorders, and maximize association with functional impairment. Individuals whose pattern matches one of the six types are diagnosed with that type; everyone else with a personality disorder is diagnosed with PD-TS. The manual emphasizes that disorder and trait constructs each add independent value in predicting antecedents (family history, child abuse history), concurrent features (functional impairment, medication use), and outcomes (hospitalization, suicide attempts), and that knowing the level of personality functioning and the trait profile informs treatment planning and prognosis — so assessment of these dimensions is relevant whether or not a personality disorder is present.

Conversation guide — Part A: AMPD

For clinicians / practitioners

• Keep the two models straight: the Section II categorical model is the official basis for coding, documentation, and insurance; the AMPD is an alternative, research-oriented, dimensional model for profiling severity and traits. See 27-personality-disorders.md for the Section II criteria and codes.
• Use the LPFS to rate overall personality functioning (0–4) and the trait domains to build a dimensional profile; use the PID-5 self- and informant-report forms to operationalize the traits, and interview data to confirm elevation.
• Remember the A–G general criteria apply to every AMPD personality disorder diagnosis, including PD-TS — check pervasiveness, stability, onset by adolescence or early adulthood, and the exclusions (another mental disorder; substance/medical effects; normal developmental stage or sociocultural environment).
• Do not convert AMPD trait profiles into Section II codes without a Section II diagnosis; when official coding is needed, apply the Section II criteria.

For patients and family members

• A personality disorder is not a judgment about character — it describes long-standing patterns of thinking about yourself and others that cause distress or problems, and that are relatively stable and hard to change without help.
• Clinicians now think of personality on a continuum (everyone has traits like emotional sensitivity, impulsivity, or distrust to some degree), not just as "has it / doesn't have it." A dimensional profile can be used to plan treatment even when a person does not have a specific personality disorder diagnosis.
• If your clinician uses terms like "personality functioning" or "trait domains," they are describing patterns of emotion, self-image, and relationships — ask them to explain in plain language what they are seeing and what it means for your care.
