title: Ultra-short version of the oral health impact profile in elderly Chileans.
abstract: OBJECTIVE
  The aim of the present study was to develop and validate an ultra-short Spanish version of the Oral Health Impact Profile (OHIP) in an elderly Chilean population.
  
  
  METHODS
  The OHIP-49Sp was applied to 490 older adults, and the seven questions with the higher impact on oral health-related quality of life were selected through linear regression. These items were applied to 85 older adults to test internal consistency (Cronbach's alpha). A discriminative validity analysis was carried out along with the assessment of sociodemographic and clinical variables. Data were analyzed using the Mann-Whitney U-test, Student's t-test and one-way anova tests with a 95% confidence level.
  
  
  RESULTS
  High internal consistency values were obtained for the OHIP-7Sp instrument (0.93). There was an association between the OHIP-7Sp scores and the presence of caries, need for complex periodontal treatment, prosthetic needs, and age younger than 70 years.
  
  
  CONCLUSIONS
  The OHIP-7Sp proved to be a consistent and valid tool to assess oral health-related quality of life in Chilean older adults, and can be incorporated in epidemiological studies that include several other targets. Geriatr Gerontol Int 2017; 17: 277-285.
