title: Psychometric characteristics of PIMS--compared to PDQ-39 and PDQL--to evaluate quality of life in Parkinson's disease patients: validation in Spanish (Ecuadorian style).
abstract: OBJECTIVE
  Analyze PIMS (Parkinson's impact scale) properties following the recommendations of the Scientific Advisory Committee of the Medical Outcomes Trust.
  
  
  METHODS
  An analytical cross-sectional study to evaluate the psychometric qualities and scale assumptions of PIMS: quality of data, acceptability, reliability, validity, internal consistency, and construct validity.
  
  
  RESULTS
  The sample included 131 patients with Parkinson's disease (PD), of which 39 (29.7%) were women. Psychometric qualities and scale assumptions, all of them are suitable.
  
  
  CONCLUSIONS
  We therefore believe that PIMS is a useful and recommendable specific tool for measuring quality of life in PD patients.
