Listing 12.08 is reserved for chronic maladaptive personality traits or impulse-control problems that pervade every setting—work, family, social life—and lead to severe functional limitations. Typical diagnoses include borderline, antisocial, narcissistic, avoidant, paranoid, or intermittent explosive disorder. When long-standing patterns of distrust, emotional lability, aggression, instability, or rule-breaking translate into marked or extreme work-related deficits (or a serious-and-persistent course despite treatment), the claimant is found disabled at Step 3 of the sequential evaluation.
Regulatory Text
12.08 Personality and impulse-control disorders, satisfied by A and B, or A and C:
- Medical documentation of a pervasive pattern of one or more of the following:
1. Distrust and suspiciousness of others;
2. Detachment from social relationships;
3. Disregard for and violation of the rights of others;
4. Instability of interpersonal relationships;
5. Excessive emotionality and attention-seeking;
6. Feelings of inadequacy;
7. Excessive need to be taken care of;
8. Preoccupation with perfectionism and orderliness;
9. Recurrent, impulsive, aggressive behavioral outbursts.
AND
- Extreme limitation of one, or marked limitation of two, of the following areas of mental functioning (12.00 F):
1. Understand, remember, or apply information;
2. Interact with others;
3. Concentrate, persist, or maintain pace;
4. Adapt or manage oneself;
OR
- The disorder is “serious and persistent” (12.00 G2): evidence over a ≥ 2-year period, with
1. Ongoing medical treatment, mental-health therapy, psychosocial support, or a highly structured setting that diminishes symptoms; and
2. Marginal adjustment—minimal capacity to adapt to changes not already part of daily life.

Key Elements
- Criterion A – Pervasive Pattern
- Document at least one of the nine maladaptive trait clusters (e.g., severe distrust, impulsivity, emotional instability).
- Functional Severity
- Paragraph B: Extreme limitation in one—or marked in any two—of the four mental-function domains.
- Paragraph C: Disorder present ≥ 2 years plus ongoing treatment/structured environment and marginal adjustment.
- Duration
- Limits must last or be expected to last 12 months (B) or meet the 2-year “serious-and-persistent” threshold (C).
Tips on Proving Listing 12.08
| Evidence | What to Gather | Why It Matters |
|---|---|---|
| Long-term psychiatric notes | DSM-5 diagnosis (e.g., borderline PD), descriptions of chronic impulsivity, unstable relationships, explosive episodes | Establish Criterion A and duration |
| Collateral reports | Statements from employers, family, probation officers about aggression, firings, legal issues, self-harm | Show pervasiveness across settings & link to “interact with others” / “adapt” domains |
| Standardized instruments | SCID-5-PD, MMPI-2, PAI, Barratt Impulsiveness Scale, OASIS for aggression | Quantify trait severity; objectify “marked/extreme” limits |
| Therapy & medication history | DBT groups, mood-stabilizers, antipsychotics, anger-management records | Demonstrate ongoing treatment (Paragraph C) & residual symptoms |
| Crisis/hospital records | ER visits for self-injury, violent outbursts, substance-induced rages | Corroborate frequency and intensity of functional breakdowns |
| Functional capacity forms | Mental RFCs noting severe limits in persistence, pace, social interaction, self-management | Directly address Paragraph B domains |
| Structured-setting proof | Notes from residential programs, intensive outpatient services, court-mandated supervision | Key for Paragraph C’s “highly structured environment” & marginal adjustment |
Testing cues from SSA Medical-Tests Guide (2024)
- Continuous Performance Test (CPT-3) to demonstrate sustained-attention deficits in impulsive disorders.
- Salivary cortisol or heart-rate variability during stress tasks may support physiologic dysregulation—but must be tied to functional evidence.
Practical Takeaway
A Social Security Disability lawyer can help build a successful 12.08 claim by weaving together consistent personality-disorder diagnoses, objective trait measures, and persuasive documentation of marked or extreme work-related limits—or a two-year history of treatment-resistant dysfunction with only marginal adaptation. Emphasize the disorder’s pervasiveness (home, work, legal), the frequency of explosive or maladaptive episodes, and the inadequacy of therapy/meds in restoring functional stability.
