title: [The adaptation and validation to Spanish of the questionnaire Aid to Capacity Evaluation (ACE), for the assessment of the ability of patients in medical decision-making].
abstract: OBJECTIVE
  To adapt and validate the Spanish version of the Aid to Capacity Evaluation scale, designed to assess the capacity of the adult in medical decision-making, both in diagnosis and treatment processes.
  
  
  METHODS
  Observational study of prospective validation.
  
  
  METHODS
  Primary and hospital care of the basic health area of Jaen.
  
  
  METHODS
  One hundred twenty-nine patients.
  
  
  METHODS
  Questionnaire which included sociodemographic variables, concerning the decision (scope, type of decision, the need for written informed consent), assessment of the capacity to the Aid to Capacity Evaluation scale and other related comorbidity (hearing loss, alcoholism, cognitive level variables with the Mini-Mental State Examination and depression by Goldberg or Yesavage test).
  
  
  RESULTS
  The tool is considered viable. The conclusions of the expert panel were favorable. The result of the criteria' validity, comparing the results with the assessment of the experts (forensic and psychiatrist) was very satisfying (P<.001). The intra-observer reliability was low (kappa=0,135). Interobserver reliability remained high (kappa=0.74). The internal consistency was awarded an alpha of Cronbach's 0,645 for the reduced model of 6 items.
  
  
  CONCLUSIONS
  The Aid to Capacity Evaluation scale was adapted to Spanish, demonstrating adequate internal consistency and construct validity. Its use in clinical practice could contribute to the identification of patients unable to make a particular medical decision and/or to give an informed consent.
