Clinical Impairment Assessment (CIA)

The CIA is a brief self-report measure of the impairment resulting from current eating disorder psychopathology. It is designed to be completed immediately after the EDE-Q. It provides both a continuous measure of the severity of secondary impairment and a threshold score associated with “caseness”.The CIA is a brief self-report measure of the impairment resulting from current eating disorder psychopathology.
