title: Psychometric evaluation of the Swedish translation of the revised Cystic Fibrosis Questionnaire in adults.
abstract: OBJECTIVE
  The CFQ-R is one of the most established disease-specific, health-related quality of life (HRQOL) measurements for patients with cystic fibrosis (CF). The aim was to evaluate the psychometric properties of the Swedish translation of CFQ-R in adults.
  
  
  METHODS
  A total of 173 CF patients answered the CFQ-R. The CFQ-R was evaluated with regard to: (1) distributional properties; (2) reliability; and (3) construct validity.
  
  
  RESULTS
  The majority of scales were negatively skewed with ceiling effects. Eight of the 12 scales had satisfactory homogeneity; 10 of the 12 scales had satisfactory test-retest reliability. On many of the CFQ-R scales expected differences were observed when patients were divided regarding disease severity, nutritional status, age, and gender.
  
  
  CONCLUSIONS
  Some weaknesses were detected, but overall the instrument has satisfactory psychometric properties.
