Enable an AI agent to organize evidence about suspected or diagnosed dissociative identity disorder, track its functional consequences, and support appropriate human-led assessment and care.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to organize evidence about suspected or diagnosed dissociative identity disorder, track its functional consequences, and support appropriate human-led assessment and care.
Dissociative identity disorder is a psychiatric diagnosis in which a person experiences two or more distinct personality states or an experience of possession, together with recurrent gaps in the recall of everyday events, important personal information, and/or traumatic events, that are not better explained by cultural or religious practice, substance use, or another medical condition.
It can be Prepare a consented assessment summary that separates reported experiences, observations, and clinician conclusions.; Track episodes, memory gaps, and functional effects using neutral prompts without eliciting identity changes.; Flag unresolved differential questions and gaps in evidence for qualified clinical review.; Offer person-approved reminders, orientation cues, and access to an existing support plan.; Route current safety concerns through an established escalation pathway using the minimum necessary information.; Compare person-defined outcomes over time and prepare questions for treatment review..
Distinguishing features
Assess discontinuity in self and agency involving multiple identity states; ordinary role changes or mood shifts alone do not establish DID. [MSD Manual](https://www.msdmanuals.com/professional/psychiatric-disorders/dissociative-disorders/dissociative-identity-disorder)
Under DSM-5-TR, establish recurrent recall gaps beyond ordinary forgetting; depersonalization alone is insufficient. [MSD Manual](https://www.msdmanuals.com/professional/psychiatric-disorders/dissociative-disorders/dissociative-identity-disorder)
Establish clinically significant distress or impairment and assess whether experiences belong to accepted cultural practices or childhood imaginative play. [MSD Manual](https://www.msdmanuals.com/professional/psychiatric-disorders/dissociative-disorders/dissociative-identity-disorder)
Do not classify from voice-hearing alone; evaluate the broader presentation and competing psychiatric, neurological, and substance-related explanations. [MSD Manual](https://www.msdmanuals.com/professional/psychiatric-disorders/dissociative-disorders/dissociative-identity-disorder)
Record whether alternate states recurrently assume executive control when distinguishing ICD-11 DID from partial DID. [ICD-11 classification changes](https://pmc.ncbi.nlm.nih.gov/articles/PMC6313247/)
Scope
+ Reported and observed discontinuities in identity, agency, and control of behavior
+ Memory gaps, retained awareness, and access to information across reported identity states
+ Diagnostic formulation, evidence provenance, competing explanations, and classification version
+ Distress, everyday impairment, episode course, and immediate support needs
+ Person-approved communication, care continuity, and response to clinician-directed treatment
- The person's complete biography, identity, or legal personhood
- Independent models of PTSD, psychotic disorders, personality disorders, and other dissociative disorders
- Neurological disease, sleep disorders, and substance effects beyond their differential-assessment links
- Determination of whether an alleged traumatic event occurred or who was responsible
- Psychotherapy protocols, medication prescribing, and autonomous clinical diagnosis
- Legal capacity, criminal responsibility, or safeguarding determinations
Characteristics
- Diagnostic formulation status
- Not assessed; under assessment; provisional; clinician-confirmed; historical; revised; disputed, with assessor and date Separates an experience report from a clinical conclusion and preserves later revisions.
- Diagnostic framework
- Named classification, edition or release, code, and assessment jurisdiction Makes the criteria behind a diagnostic assertion explicit.
- Identity and agency discontinuity
- Narrative description with reported, observed, clinically interpreted, or uncertain evidence status Records the relevant experience without inferring it from names, appearance, or conversational style.
- Executive-control pattern
- Intrusion without reported takeover; reported takeover; observed behavioral transition; unclear, with context Supports assessment of how discontinuities affect action and the differential formulation.
- Recall-gap burden
- Reported episodes per stated observation period and estimated minutes or hours unaccounted for; unknown permitted Makes changes in lost time reviewable without treating unobserved periods as symptom-free.
- Awareness and information access
- Person-described access to particular events or information across reported states; shared, partial, unavailable, or unknown Helps identify continuity needs without assuming a fixed set of identities.
- Functional interference
- Domain-specific narrative or named scale with version, score, date, and reporting source Connects assessment to missed obligations, self-care difficulties, and the person's priorities.
- Current safety assessment
- Not assessed; no immediate concern identified; concern requiring review; urgent concern, with evidence and timestamp Bases escalation on current circumstances rather than the diagnosis alone.
- Support-plan accessibility
- Accessible; partly accessible; inaccessible; untested, for a specified plan and context Shows whether the person can retrieve essential support when recall or orientation is disrupted.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 7 bundles · 13 layers · 21 findings · 37 questions.
Identity and agency discontinuity Represent experiences of altered selfhood and control without imposing an identity inventory.
Recognition requires evidence about discontinuity, while respectful interaction requires preserving the person's own language.
Experience and language
Capture how the person describes changes in self-experience.
Self and agency account
Record concrete examples separately from diagnostic interpretations or inferred identity labels.
- What changes in ownership of thoughts, actions, or bodily experience does the person describe? definition
- Which terms does the person prefer, and which labels originated with an interviewer or other source? provenance
Control and transitions
Describe reported intrusions and transitions in behavioral control.
Transition evidence
Keep subjective takeover experiences, externally observed changes, and clinical interpretation distinguishable.
- What was reported or observed before, during, and after a possible transition, and by whom? provenance
- Does the account concern altered feelings, an intrusive impulse, or a change in executive control? boundary
- Over what observation period were these events recorded, and what intervals remain unknown? measurement
Memory and continuity Represent recall gaps and practical access to information across time and reported states.
An agent needs to distinguish missing information from established events and help maintain everyday continuity.
Recall gaps
Describe unremembered intervals without filling them with inferred events.
Unaccounted intervals
Record the bounds, discovery, and uncertainty of each reported gap.
- Which everyday or autobiographical events cannot be recalled, and how precisely can the interval be bounded? measurement
- What independently recorded information, if any, establishes what occurred during that interval? provenance
Information access
Capture practical continuity needs without assuming all reported states have equal recall.
Essential information continuity
Identify which reminders and records the person wants available during disrupted recall.
- Which appointments, recent decisions, or support instructions become difficult to retrieve, and in what circumstances? measurement
- What person-approved record could preserve continuity without revealing unwanted sensitive material? action
Diagnostic boundaries and evidence Maintain the clinical formulation, competing explanations, and limits of available evidence.
The model must support review without turning a symptom narrative or screening result into a diagnosis.
Criteria and assessment
Associate conclusions with a named diagnostic framework and accountable assessment.
Criterion-level formulation
Record each criterion as supported, unsupported, unresolved, or not assessed, with its evidential basis.
- Which classification and version did the assessor use, and which requirements remain unresolved? definition
- Who made the formulation, using which interviews, records, or instruments? provenance
- Was a questionnaire used for screening, symptom monitoring, or diagnostic assessment? boundary
Alternative explanations
Track differential questions and contextual interpretation without presuming exclusion.
Differential review
Maintain evidence for competing or coexisting explanations rather than requiring a single explanation for every symptom.
- What evidence distinguishes this presentation from partial DID, other dissociative disorders, PTSD, or psychotic symptoms? boundary
- Which neurological, sleep-related, medication, or substance explanations require assessment? action
Cultural and developmental context
Record the context needed to interpret identity-related experiences without pathologizing unfamiliar language or practices.
- How does the person understand the experience within their cultural, spiritual, and developmental context? definition
- What evidence distinguishes unwanted impairment from accepted practice, voluntary enactment, or developmentally expected play? boundary
Course and functional impact Connect discontinuities and recall difficulties to changes in everyday functioning.
State judgments need time-bounded consequences and personal baselines rather than a count of named identities.
Temporal pattern
Separate symptom history, recognition history, and current observations.
Onset and context
Record when experiences were first noticed and which circumstances accompany changes without asserting causation.
- When were experiences first remembered, documented, and clinically recognized, and where do those dates differ? provenance
- Which contexts precede worsening or improvement, and how consistent is that association? measurement
Everyday consequences
Assess the person's distress and the activities affected by discontinuity.
Functional burden and priorities
Record concrete consequences and desired improvements in the person's terms.
- Which missed tasks, relationship difficulties, or self-care disruptions are associated with reported episodes? measurement
- Which change would most improve the person's daily life, and what observation would demonstrate it? action
Safety and agent interaction Specify how an agent should respond when recall, orientation, or continuity of a conversation becomes uncertain.
The agent needs explicit boundaries for immediate support, sensitive disclosure, and potentially suggestive interaction.
Immediate support
Connect current evidence to an existing safety and support pathway.
Current safety and plan access
Assess immediate circumstances without assigning risk from the diagnostic label or a reported identity state.
- Is there current evidence of self-harm intent, unsafe lost-time activity, disorientation, or inability to meet essential needs? measurement
- Which agreed support contact or urgent-care pathway applies, and can the person access it now? action
Consent and neutral language
Preserve person-level permissions while respecting preferred ways of describing experience.
Disclosure and interaction boundaries
Define permissions for sensitive records and prohibit agent-led attempts to evoke identities or reconstruct missing memories.
- What may the agent retain or disclose, and what clarification is needed if the person no longer recalls an earlier permission? action
- How will the agent acknowledge distress without asserting that an unverified identity, event, or explanation is established? boundary
- Which requests require referral to a clinician rather than prompting a switch or attempting memory recovery? action
Care coordination and outcomes Represent the person's agreed care goals, support arrangements, and changes during treatment.
The model must distinguish helpful support from clinical intervention and make improvement reviewable without prescribing one identity outcome.
Agreed care
Link condition-related needs to accountable providers and a person-approved plan.
Goals and responsibilities
Record chosen goals for daily functioning, continuity, and identity-related distress together with who directs care.
- What goals has the person agreed with their clinician, including any goals concerning cooperation or integration? action
- Which support tasks may the agent perform, and which decisions belong to the treating clinician? boundary
Response and review
Track benefits, burdens, and reasons to revisit the plan.
Meaningful change
Compare functional outcomes and reported continuity against an explicit baseline without equating fewer identity labels with recovery.
- What changed in recall gaps, distress, daily functioning, or support dependence over the review interval? measurement
- Which new difficulties or unmet goals warrant clinician review, and what evidence should accompany it? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

- Iatrogenic shaping of identities in highly suggestive interview or therapy contexts, especially where recovered-memory techniques are used.
- Factitious presentation or malingering, particularly in forensic settings, which can both false-positive the diagnosis and discredit genuine cases.
- Self-harm, suicidality, and high psychiatric comorbidity (PTSD, depression, substance use), which drive most acute medical risk rather than identity switching itself.
- Functional impairment from amnesia, time loss, and conflicting self-states (work, parenting, legal, financial).
- Stigma and sensational media portrayals that distort clinical presentation and can affect jury and clinician judgment.
- Which of these failure modes and hazards hold for the sense of dissociative identity disorder this model covers, and on what evidence? provenance
Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- North American DSM-5-TR practice uses a single DID category with possession-form and non-possession-form specifiers in description; ICD-11 (used more widely internationally) splits DID (6B64) from partial DID (6B65).
- Possession-form presentations are more often reported in settings where spirit-possession is a culturally sanctioned idiom; DSM-5-TR requires that the disturbance not be a normal part of broadly accepted cultural or religious practice.
- The older name multiple personality disorder remains in popular and some legal language; ICD-10 still nested the concept under dissociative [conversion] disorders (F44).
- Prevalence estimates and clinical recognition vary sharply by country and service; DID is diagnosed more often in some specialist trauma clinics in North America, the Netherlands, and parts of Europe than in general psychiatric services elsewhere.
- Forensic acceptance of DID as a basis for insanity or diminished responsibility is jurisdiction-specific and often skeptical.

Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Partial dissociative identity disorder (ICD-11 6B65) - A non-dominant personality state intrudes on consciousness and agency but does not recurrently take full executive control of the person's functioning, so ICD-11 DID (6B64) is not met.
- Other specified / unspecified dissociative disorder, including DSM-5-TR 'identity disturbance due to prolonged and intense coercive persuasion' - Identity disruption or dissociative symptoms are present, but the combination of two or more distinct personality states plus recurrent amnesia required for DID is not fulfilled.
- Post-traumatic stress disorder, including dissociative subtype - PTSD is organized around trauma re-experiencing, avoidance, and hyperarousal; the dissociative subtype adds depersonalization/derealization without requiring distinct personality states that take control and associated identity amnesia.
- Borderline personality disorder - BPD identity disturbance is a persistently unstable self-image and affect, not recurrent, relatively enduring personality states with amnesia for everyday events; the two can co-occur and need independent assessment.
- Schizophrenia and other psychotic disorders - Auditory hallucinations and passivity phenomena in psychosis lack the structured, recurrent personality states and autobiographical amnesia of DID; insight, thought disorder, and negative symptoms help separate them, though DID patients may hear voices of other states.
- Bipolar disorder - Mood-episode polarity and duration (days to weeks of mania/depression) explain state changes; DID switches are typically faster, identity-organized, and accompanied by amnesia rather than a primary mood syndrome.
- Complex partial seizures / temporal lobe epilepsy and other neurological amnestic syndromes - Epileptic events have EEG/clinical seizure signatures, stereotyped auras, and post-ictal confusion; DID amnesia is psychologically organized and not explained by a medical condition (DSM/ICD exclusion).
- Malingering or factitious disorder, and culturally normative possession - Malingering is judged by secondary-gain evidence and validity testing; religious or ceremonial possession is excluded when it is a normal, accepted practice and not distressing or impairing in the required clinical sense.
