title: Psychometric attributes of the Cervantes short-form questionnaire for measuring health-related quality of life in menopausal women.
abstract: OBJECTIVE
  To analyse the psychometric properties of the Cervantes scale short-form (SF) in the peri- and post-menopausal periods.
  
  
  METHODS
  Outpatients women 45-65 years with menstrual problems associated with the climacteric syndrome were analysed. Original and SF versions of the Cervantes scale were administered along with the EuroQol-5D (EQ-5D) and work productivity and activity impairment questionnaire (WPAI) scales. Conceptual model, burden of administration, feasibility, reliability, criteria validity and construct validity were assessed.
  
  
  RESULTS
  317 women [55.7±5.3 years (mean±standard deviation)] were recruited: 75.4% were post- and 22.3% were peri-menopausal. The Cervantes-SF was completed in 2.5±1.6min, and 86% answered all items. Cronbach's α was 0.820, and ranged from 0.510 (Aging) to 0.918 (Vasomotor Symptoms) for individual dimensions. The scale structure matched the structure of the original version, χ(2)/(degrees of freedom)=3.6, Comparative Fit Index=0.848, Tucker-Lewis Index=0.850, and root mean square error of approximation=0.099, although differences were found between sexual activity statuses. Criteria validity was good (r=0.890), concurrent validity was congruent with a priori hypothesis using either the EQ-5D or the WPAI scales. The scale discriminated significantly the severity of both vasomotor and genital climacteric associated symptoms.
  
  
  CONCLUSIONS
  The Cervantes-SF has shown good psychometric properties for measuring Health related quality of life in peri- and post-menopausal women who regularly attended gynaecology clinics in Spain.
