Attachment Difficulties
Standardised tools for assessing attachment difficulties in early childhood
Attachment difficulties in early childhood (ICD-11 6B44) are assessed by combining structured observation and caregiver interview — the Strange Situation Procedure, Attachment Q-Sort, Disturbances of Attachment Interview, Crowell Procedure and story-stem narratives — never a single test. A clinical AbilityScore and any diagnosis are formed only at a Pinnacle centre.
A pattern of disturbed attachment behaviour is best mapped, never inferred — standardised observation and structured history are what turn a clinical hunch into a measured profile.
In short
Attachment difficulties in early childhood (ICD-11 6B44) are assessed through a convergence of structured observation, caregiver interview and developmental screening — not a single test. The reference paradigm remains the Strange Situation Procedure (SSP) for classifying attachment patterns in 12–20 month olds, complemented by the Attachment Q-Sort (AQS) for naturalistic home observation. Clinically, relationship and caregiving context must be captured alongside the child.The instruments in practice
- Strange Situation Procedure (Ainsworth): the validated laboratory paradigm for classifying secure/insecure and disorganised patterns in infancy.
- Attachment Q-Sort (Waters): observer-rated, ecologically valid, suited to home or naturalistic settings up to ~4 years.
- Disturbances of Attachment Interview (DAI): semi-structured caregiver interview screening for reactive attachment and disinhibited social engagement features.
- Crowell Procedure / parent–child interaction assessments: structured dyadic observation of caregiving and child response.
- Manchester Child Attachment Story Task / story-stem narratives: representational measures for preschoolers (~3–8 years).
These map to ICD-11 differentiation between reactive attachment disorder and disinhibited social engagement disorder; sensory, communication and developmental screening should run in parallel to exclude alternative explanations.

What to watch
Watch for converging evidence across observation and caregiver history rather than a single test result; ensure sensory, hearing and developmental screening run in parallel to exclude alternative explanations for disturbed relational behaviour.
Try this at home
When co-administering, capture the caregiving context as carefully as the child's behaviour — attachment is dyadic, and the relationship is part of the measure.

Frequently asked
Is there a single diagnostic test for attachment difficulties?
No. Assessment relies on a convergence of structured observation (e.g. Strange Situation Procedure, Attachment Q-Sort), caregiver interview (e.g. Disturbances of Attachment Interview) and developmental screening. A clinical diagnosis is established only by a qualified clinician at a Pinnacle Blooms Network centre.
At what age can the Strange Situation Procedure be used?
It is validated for infants roughly 12–20 months. For preschoolers, observer-rated and narrative measures such as the Attachment Q-Sort or story-stem tasks are more appropriate.
How does ICD-11 frame attachment difficulties?
ICD-11 (6B44) distinguishes reactive attachment disorder from disinhibited social engagement disorder. Standardised tools help differentiate these patterns and exclude alternative developmental explanations.
