Overview

From Appendix III:
"The Clinical Impairment Assessment questionnaire (CIA) is a 16-item self-report measure of
the severity of psychological impairment due to eating disorder features (Bohn and Fairburn, 2008).
It focuses on the past 28 days. The 16 items cover impairment in domains of life that are typically affected by
eating disorder psychopathology: mood and self-perception, cognitive functioning, interpersonal functioning and work performance.
The purpose of the CIA is to provide a simple single index of the severity of psychosocial impairmente secondary to
eating disorder features."

Instructions

Instructions are originals with minor edits to refer to the computer set-up.

Scoring

The 16 questions are set up as radiobutton questions with 4 answer choices.
There are 4 questions per surveyPage - participants can go back and forth.
No answer is required.
