Cross-cultural adaptation and validation into Spanish of the deprescription questionnaire in the elderly patient

Background and objective: In 2017, a questionnaire was developed in Italian with the aim of determining clinicians' perceptions of deprescription in the elderly population. The objective was to translate and cross-culturally adapt this deprescription questionnaire to Spanish. Methods: Forward and blind-back translations, followed by a synthesis and adaptation by a third translator. Development of an expert panel to evaluate the adequacy of the translation, the understandability of the translated question and the usefulness of each question. A comprehensibility analysis was carried out on physicians familiar with deprescription. Results: The Spanish version of the questionnaire was obtained, where the average degree of difficulty in the direct and the back-translation was low/moderate. In the first phase of the panel of experts, 4 questions had sections considered "indeterminate" and one question was "doubtful". After the second phase, all the questions were considered "adequate" except for one. Conclusions: This is the first cross-cultural adaptation to Spanish of this questionnaire, which will provide a tool to assess clinicians' perception of this practice and establish improvements to carry out this activity.
