- Brief Summary
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.

- Outpatients were eligible for the study if they had been diagnosed with anorexia nervosa, bulimia nervosa, or an eating disorder not otherwise specified (EDNOS) by psychiatrists based on criteria established in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) (American Psychiatric Association, 1994), and provided written informed consent to participate.
- Patients were excluded if they had a malignant, severe organic disease, could not complete the questionnaires because of language barriers, or did not give written informed consent to participate in the study.

Group Intervention Description Eating disorder patients by type of compensating behavior. Adaptation of the CIA 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.
- Primary Outcome Measures
Name Time Method CIA questionnaire Up to 2 years The CIA (v. 3.0) (Bohn et al., 2008) is a 16-item self-report measure of psychosocial impairment secondary to features of an eating disorder. This questionnaire measures three domains of impairment-personal, social, and cognitive-attributable to eating habits, exercising, or feelings about eating, shape, or weight over the previous 28 days. Items are rated on a four-point Likert scale, ranging from 0=''Not at all'' to 3=''A lot.'' A global CIA score ranging from 0 to 48 is calculated to provide a global index of the severity of psychosocial impairment due to eating disorder pathology during the past 28 days. A higher score indicates greater impairment. Subscale scores can be calculated to determine the three domains of impairment (personal, social, and cognitive). The original report of the CIA's psychometric properties supported adequate reliability and validity of the measure within a clinical sample of patients with eating disorders (Bohn et al., 2008).
- Secondary Outcome Measures
Name Time Method Eating Attitudes Test-12 (EAT-12) Up to 2 years Eating problems were measured by the EAT-12 (Lavik, Clause \& Pedersen, 1991). It uses a 4-point scale, from never (score 0) to always (score 2). The EAT-12 yields three factors: dieting, bulimia and food preoccupation, and oral control. Previous studies have supported its validity as a measure of disordered eating (Wichstrøm, Skogen \& Øia, 1994; Wichstrøm, 1995). The internal consistency was a 0.71.
Health-Related Quality of Life in ED-short form (HeRQoLED-s) Up to 2 years ED patients' quality of life was evaluated using the Health-Related Quality of Life in ED-short form (HeRQoLED-s) (Las Hayas et al, 2007; Las Hayas, Quintana, Padierna, Bilbao \& Munoz, 2010). This questionnaire consists of 20 items distributed into two domains: social maladjustment and mental (α=0.91) and functional health (α=0.90). The higher the score, the lower the quality of life. This measure has been used successfully with Spanish-speaking populations (González, Padierna, Martín, Aguirre \& Quintana, 2012; Las Hayas et al., 2006; Martín et al., 2011; Muñoz, 2009; Padierna et al., 2012).
