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.

Adaptation of the CIA

Adaptation of the CIA into Spanish was performed using the backward-forward translation process, which ensures conceptual. Forward translation into Spanish was carried out by two independent native Spanish speaking translators who were fluent in English. Two other independent translators, totally blind to the original version, whose native language was English and who were fluent in Spanish, back-translated the consensus version into English. After reaching consensus on a final translated version, it was sent to the CIA's original author (Dr. Bohn) who gave her approval. We undertook a cognitive debriefing process with a group of 5 ED patients to identify any problems with language. The pre-final version was administered to two small groups, one made up of patients (a sample of 5 respondents) and the other of clinical experts (2 psychiatrists and 2 psychologists who were experts on ED).
