Randolph Attachment Disorder Questionnaire

The Randolph Attachment Disorder Questionnaire or "RADQ" is one of the better known checklists and is used by attachment therapists and others, but critics consider it lacks specificity and is unvalidated.

The checklist includes 93 discrete behaviors, many of which either overlap with other disorders, like Conduct Disorder and Oppositional Defiant Disorder or are not related to attachment difficulties.
