title: [Validation of the Life-Support Preferences Questionnaire (LSPQ) for its use in Spain].
abstract: OBJECTIVE
  To validate the Life-Support Preferences Questionnaire (LSPQ) for its use in Spain.
  
  
  METHODS
  Three-stage study: a) translation and linguistic adaptation; b) evaluation of its validity; and c) validation of its psychometric properties.
  
  
  METHODS
  Nine primary care nursing clinics and 2 university classes in Granada, Spain.
  
  
  METHODS
  Patients who were of age and were first- or second-year university students, without any cognitive deterioration.
  
  
  METHODS
  The equivalence of the translation and the original was checked by bilingual people; its linguistic and grammatical standard was appraised by experts in Spanish. The validity of the questionnaire was evaluated by 15 judges-experts and 20 patients; linguistic complexity (Szigriszt index); stability in time (McNemar test); internal consistency (Cronbach's alpha).
  
  
  RESULTS
  a) 2 bilingual people did a translation that was reviewed by 6 experts in Spanish. After alterations suggested by the experts, the bilingual people ratified its equivalence with the original; b) 15 experts affirmed that each item was a good indicator of care preferences at the end of life; c) 20 users confirmed the acceptability and comprehensibility of the questionnaire; d) reliability: 299 participants out of the 369 initially selected filled in the questionnaire; and e) its stability was 0.92; and its internal consistency, 0.85.
  
  
  CONCLUSIONS
  The LSPQ questionnaire in Spanish (LSPQ-e) is a reliable tool, designed to help patients to clarify their care and treatment preferences at the end of their lives.
