About

The Clinical Impairment Assessment (CIA) assesses psychosocial impairment secondary to an eating disorder. The aim of this study was to create and validate a Spanish-language version of the CIA. Using a forward-backward translation methodology, we translated the CIA into Spanish and evaluated its psychometric characteristics in a clinical sample of 178 ED patients. Cronbach's alpha values, confirmatory factor analysis (CFA), and correlations between the CIA and the Eating Attitudes Test-12 and the Health-Related Quality of Life in ED-short form questionnaires evaluated the reliability, construct validity, and convergent validity, respectively. Known-groups validity was also studied comparing the CIA according to different groups; responsiveness was assessed by means of effect sizes.

Eating disorder patients by type of compensating behavior.

Description:

Data collection started in 2010; one year follow-ups were conducted through 2011-2012. Psychiatrists collaborating in the study informed personally their patients about the objectives of the study, and recorded the sociodemographic information, including age, gender, marital status, level of education, employment status, and people with whom the patient lived. Those who agreed to take part were also sent the questionnaires and informed consent form by mail. They were asked to return these by mail using an enclosed, pre-stamped envelope. Two reminders also were sent at intervals of 15 days to those who did not respond to the first mailing.
