The Strange Situation Procedure

Activity: Participating in or organising an event typesParticipation in workshop, seminar, course


The Infant Strange Situation is an instrument for assessing quality of attachment in 11-17-month-old infants. The procedure was developed by Mary D. Salter Ainsworth and has been expanded by both Mary Main and Judith Solomon (who added the notion of disorganization) and also by Patricia M. Crittenden (who added the A/C and pre-compulsive classifications).

The Ainsworth Infant Strange Situation involves a 20-minute laboratory procedure and takes three people to carry out (plus the child and mother). Classification is based on careful review of the videotape and takes approximately one-half hour per videotape.
