IntroductionDelirium is a frequent and serious acute neuropsychiatric syndrome, namely in elderly hospitalised patients, described as a psychologically traumatic experience by patients, family/caregivers and health professionals(HPs). In this context, the Delirium Experience Questionnaire (DEQ) was developed as a face-valid instrument assessing the delirium experience recall and the degree of distress related to delirium episodes in patients, family/caregivers, and HPs.AimTo present the translation and cultural adaptation of the Portuguese version of DEQ (DEQ-PT).MethodsThe translation process followed ISPOR guidelines. After preparation, forward translation, reconciliation, back translation, back translation review, harmonization and cognitive debriefing (involving experts’ consensus), the DEQ-PT was tested (pre-test) in a group of elderly patients with delirium(≥ 65 years) in two Intermediate Care Units (Intensive Care Medicine Service-CHSJ, Porto). Exclusion criteria were: brain injury, blindness/deafness, unable to communicate, and Glasgow Coma Scale ≤ 11. Their families were also assessed, as well as the HPs (physicians/nurse) in charge of patients during hospitalisation.ResultsAfter obtaining permission to use the instrument, the DEQ was successfully translated into Portuguese, with harmonization of all new translations. Pre-test included a group of 5 patients, 5 families and 5 nurses. This version revealed good cognitive equivalence with the original English version and also a good level of comprehensibility.ConclusionThe DEQ-PT showed good feasibility, being suitable, quick and easy to use in the assessment of delirium experience in intermediate care units. These findings will be further developed by an ongoing validation study.AcknowledgementThis work was supported by foundation for science and technology (SFRH/BPD/103306/2014).Disclosure of interestThe authors have not supplied their declaration of competing interest.
