Psychometric attributes of the Cervantes short form questionnaire for measuring health related quality of life in menopausal women.
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 a 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, kh(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. CONCLUSION 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.
