title: Evaluation of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) in persons with heart disease: a pilot study.
abstract: BACKGROUND
  As part of preparation for a Swedish multicentre study, exploring sexual and married life in patients with myocardial infarction and their partners, a Swedish validated instrument was required.
  
  
  OBJECTIVE
  The aim of this pilot study was to evaluate the validity and reliability of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) among persons with a heart disease.
  
  
  METHODS
  A convenience sample of 79 persons (47 men and 32 women) living with a heart disease was recruited from the members of the National Association of Heart and Lung Patients. They completed a Swedish version of the WSFQ on two occasions.
  
  
  RESULTS
  Two separate factor analyses each revealed a two-factor structure on both occasions: "Sexual appetite" and "Sexual expectations" with gender-neutral questions and "Sexual sensitiveness" and "Sexual ability" with gender-specific questions. Cronbach's alpha coefficients ranged from 0.48 to 0.86 and test-retest values for all but one question exceeded 0.70.
  
  
  CONCLUSIONS
  The Swedish version of the WSFQ showed good validity and stability and acceptable internal homogeneity. Extended evaluations of the questionnaire are recommended.
