Detachment (ICD-11) — The Trait Domain of “Social Withdrawal + Emotional Detachment” in Personality Disorders
1) Big Picture & Concept
In ICD-11, individuals receive a primary diagnosis of “Personality Disorder” (with specified severity: Mild / Moderate / Severe). Then, five trait qualifiers are added, one of which is Detachment, to describe the “flavor” of each person’s personality impairment. This is a dimensional model (a spectrum), not a rigid categorical “type” system.
Wikipedia
Detachment typically reflects pulling away both socially and emotionally: avoiding or rejecting close interactions, showing limited affect, being cool/aloof or reserved, and reduced capacity for pleasure (anhedonia) overall.
(Clinical descriptions derived from WHO summaries and contemporary reviews.)
Wikipedia
ICD-11’s trait-dimensional approach is regarded as clinically usable and consistent with prior research; a Borderline pattern qualifier can be added when BPD features are prominent.

2) Core Phenomenology
Detachment comprises two interlocking dimensions:
A) Social detachment
- Avoids intimacy and social engagement; low interest in social activities.
- Often sends “social rejection signals” (responses that lead others to back off) → few friends/close ties.
- Tends to choose roles that minimize interpersonal contact at work.
Wikipedia
B) Emotional detachment
- Reserved/indifferent presentation; minimal affect display (verbal and nonverbal).
- Anhedonia: reduced enjoyment/interest; in severe cases, may feel almost no reaction to good/bad events.

3) Common Facet-Level Structure
Development work on the PiCD and follow-up factor studies suggest Detachment contains key facets such as:
Aloofness, Social isolation, Anhedonia, Unassertiveness.

4) Cross-Walk to Legacy “Types”
Systematic syntheses show Detachment maps most strongly onto Schizoid PD (marked preference for solitude, lack of desire for close relationships, low affect). While ICD-11 no longer uses the “Schizoid” label, the trait domain conveys the same profile.
Frontiers
Overall, the ICD-11 model cross-walks reasonably with DSM-5-AMPD trait structure (Detachment ↔ Detachment). At the same time, ICD-11 separates Anankastia as its own domain and does not include Psychoticism in the personality trait model (placed elsewhere in ICD).

5) Assessment — Tools & Approach
- PiCD (Personality Inventory for ICD-11):
60-item self-report covering 5 domains (12 items each); validated in community and clinical samples, with strong construct validity and links to the Big Five; informant versions (IPiC) are also available.
BioMed Central - Clinician-reported traits:
Clinician-rated domain structure aligns with the ICD-11 model (confirming Detachment as one of the five core domains).
PubMed - “Severity-first → trait pattern” workflow:
First rate impairment in self/interpersonal functioning; then use Detachment (and other domains) to describe the pattern that produces dysfunction.
PMC
6) Differential Pointers
- Depression/Anxiety disorders: typically episodic, whereas Detachment reflects a low-flexibility, enduring personality style.
- Avoidant-style (with NA): high threat/rejection interpretation plus withdrawal → an “anxious-avoidant” picture (Negative Affectivity + Detachment).
- Borderline pattern: affective lability may occur, but BPD generally seeks relationships (albeit tumultuous), rather than not wanting them as in Detachment; if BPD criteria are clear, add the Borderline pattern qualifier.

(Note: These are contemporary clinical heuristics aligned with ICD-11 indicators.)
7) Clinical Impact
- Relationships: low intimacy → small social network and reduced social support.
- Quality of life / Work: tendency to pick solitary roles may limit soft-skill development; low reward experience (anhedonia).
- Common comorbidity: when high Detachment co-occurs with other domains (e.g., NA / Anankastia), risk of depression/anxiety and avoidance of rewarding activities increases (based on PiCD/summary reviews).

8) Support & Interventions with Emerging Evidence
While ICD-11 is a classification (not a treatment manual), practice guidelines and reviews suggest:
- CBT (cognitive-behavioral):
Behavioral activation / scheduled rewarding activities; graded exposure to social situations; social-skills training (initiating/maintaining conversation). - Schema Therapy:
Target disconnection/unrelating and low-pleasure schemas; experiential methods to enhance emotion awareness and needs articulation. - MBT / Interpersonal Therapy (IPT):
Strengthen mentalizing (seeing self/others’ mental states) and foster safer relational patterns. - Environmental coaching:
Build low-threat social cues, set small/frequent/achievable approach goals to reduce avoidant retreats.
(Fits real-world ICD-11 use: rate severity → match skills/context → monitor with PiCD/IPiC.)

9) Brief Clinical Vignette
“B.”, 29, graphic designer, chooses night shifts to avoid people, declines team activities, gives minimal replies and avoids eye contact. Reports: “Things I used to enjoy as a kid now feel empty” (anhedonia). PiCD shows high Detachment (with moderate Anankastia). Plan: CBT + behavioral activation + stepwise social-skills training, with PiCD follow-ups every 8–12 weeks.
10) Blog-Ready Communication Tips (Use as-is)
- Use an H2: “What Detachment Looks Like in Daily Life” with 6–8 bullets extracted from Sections 2–3.
- Add a Self-Check (not diagnostic) box: short prompts like “Do I avoid group work unnecessarily?” / “Do I feel far less enjoyment from past hobbies?” (point readers to seek professionals if life impact is significant).
- Close with a Call-to-Action: link to NA/Anankastia posts to compare patterns (trait patterning).
