DSM diagnostic criteria
A pervasive pattern of detachment from social relationships and a restricted range of emotional expression in interpersonal settings, beginning by early adulthood.
- 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.
- 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
- 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
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.
- Low-intensity supportive therapy
- Cognitive therapy targeting isolation schema
- Social-skills / graded social exposure
- 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.
- 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
Modest. Sustained but limited gains in functioning are realistic; full social engagement is usually neither achievable nor the patient's goal.
