BACKGROUND:Insecure attachment in infancy is associated with a range of later socioemotional problems; therefore, it is important to identify at-risk children so that support can be provided. However, there are currently no well-validated brief measures of infant attachment. The aim of this study is to create a brief version of the Attachment Q-Sort (AQS), one of the gold-standard measures of attachment. METHOD:Data was used from the National Institute of Child Health and Development Study of Child Care and Youth Development (N = 1,364). The factor structure of the AQS was explored, and Item Response Theory was used to select a reduced number of items. Convergent validity of the shortened measure was assessed through associations with the Strange Situation Procedure. Correlations with sensitivity, externalising, and social competence were also examined. RESULTS:The Brief Attachment Scale (BAS-16) was created consisting of two scales of eight items, relating to (a) harmonious interaction with the caregiver and (b) proximity-seeking behaviours. The BAS-16 showed comparable convergent, discriminant, and concurrent validity to the full AQS. CONCLUSION:This brief version of the AQS shows potential as a screening measure for insecure attachment in infancy. Further development and validation is required in separate samples.
