title: Everyday functions and needs of individuals with disability: a reliability and validity study based on the principles of the ICF.
abstract: BACKGROUND
  The goal of this study was to develop and validate a questionnaire to measure everyday functions of individuals with disability based on the principles of the International Classification of Functioning, Disability, and Health (ICF).
  
  
  METHODS
  Participants consisted of 1116 individuals. The final sample was representative for the following criteria: disability, gender, age, and residence. The questionnaire consisted of 4 sections. In addition to general and demographic questions, we developed 258 statements about everyday functioning based on the items from the ICF.
  
  
  RESULTS
  The Cronbach alphas showed adequate internal reliability for the different scales: range of Cronbach alphas on the main sample: .624 to .904; range of Cronbach alphas on the test-retest sample: .627 to .921. Correlations with validating scales were typically high. Individuals with disability showed lower mean scores in each area compared to controls but the profiles of the different groups with disability varied across areas. The data also showed that physical status by itself does not determine everyday functioning. Several participants across groups showed that despite severe physical disability, one may exhibit high values of everyday functioning and well-being.
  
  
  CONCLUSIONS
  Our questionnaire is a valid and reliable method to measure everyday functioning in individuals with different disabilities. The various versions of the questionnaire (computerized, paper-pencil, easy to understand) ensure that everyone's functioning and well-being can be assessed.
