Intellectual disability and attachment theory among adults: An early systematic review.

Background: The aim of this systematic review was to identify and critically appraise empirical research regarding attachment theory among adults with an intellectual disability. Method: A systematic search was carried out in Psycinfo and CINHAL databases. Only five studies met selection criteria. Results: Three main findings were identified: (1) there is a scarcity of empirical research regarding attachment concepts among adults with ID, related to a lack of established measures among this population; (2) there is some evidence that insecure attachment among adults with ID is associated with adverse early life experiences and current mental health difficulties; and (3) there is conflicting evidence that attachment behaviours may present as challenging to supporters. Conclusions: Further research seeking valid and reliable measures is needed with greater numbers of participants with diverse levels of ID. [ABSTRACT FROM AUTHOR]
