DSM diagnostic criteria

Essential feature

A pervasive pattern of detachment from social relationships and a restricted range of emotional expression in interpersonal settings, beginning by early adulthood.

Criteria — 4 or more of 7 criteria
  • Neither desires nor enjoys close relationships, including being part of a family.
  • Almost always chooses solitary activities.
  • Has little, if any, interest in sexual experiences with another person.
  • Takes pleasure in few, if any, activities.
  • Lacks close friends or confidants other than first-degree relatives.
  • Appears indifferent to the praise or criticism of others.
  • Shows emotional coldness, detachment, or flattened affectivity.
Key differentials
  • Avoidant PD (desires closeness but fears rejection — schizoid does not desire it)
  • Schizotypal PD (adds cognitive/perceptual distortions)
  • Autism spectrum disorder (developmental history, social-communication deficits)
  • Negative symptoms of schizophrenia / prodrome
  • Depression with anhedonia (episodic vs. lifelong trait)

Treatment

Goals
  • Increase tolerance of and limited engagement in social contact
  • Build a vocabulary for inner experience without forcing intimacy
  • Reduce functional impairment (work, self-care) rather than impose a social ideal
Strategy

Accept the patient's preference for distance and work at the edge of tolerance. Avoid pushing for warmth or emotional disclosure too fast. Use the therapy relationship as a low-demand, safe rehearsal space for relatedness, framing goals in the patient's own terms.

Modalities
  • Low-intensity supportive therapy
  • Cognitive therapy targeting isolation schema
  • Social-skills / graded social exposure
Interventions
  • Keep sessions structured and predictable; tolerate silences without filling them anxiously.
  • Name and label affect tentatively to expand emotional granularity.
  • Graded behavioural assignments to add small, manageable social contact tied to the patient's interests.
  • Avoid interpreting the detachment as resistance.
Common obstacles
  • Low motivation for change; treatment often initiated by others
  • Therapist over-investment in connection the patient does not seek
  • Anhedonia limits reinforcement of new behaviour
Prognosis

Modest. Sustained but limited gains in functioning are realistic; full social engagement is usually neither achievable nor the patient's goal.
