UNLABELLED:This article summarizes the work done to adapt and to validate the short form of Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) for its use in Spain. It will become the first validated questionnaire in this country for the evaluation of the sexual function in women with Pelvic Organ Prolapse and/or Urinary Incontinence. PATIENTS AND METHOD:49 women who visited a specialized unit with symptoms of pelvic floor were included. Patients filled in the Spanish version of the questionnaire to validate (PISQ-12), the Urinary Incontinence Questionnaire (ICIQ-UI-SF); the Female Sexual Function Questionnaire (FSM) and the Bladder Control Autoevaluation Questionnaire (CACV). Factibility, reliability and validity of the new questionnaire were evaluated. RESULTS:Factibility: 99.83% of the sample answered all the items (only one patient did not answer one of the items); average administration time 3.5 (1.5) minutes. RELIABILITY:Cronbach's alpha was 0,829. VALIDITY:PISQ-12 correlation with FSM was 0,71; with ICIQ-UI-SF it was -0,038; with the CACV "symptoms" dimension the correlation was -0,30 and with the "discomfort" dimension it was -0,40. The existence of the same three dimensions of the PISQ-12 original version in the adapted Spanish questionnaire is checked through a factorial analysis. The score in PISQ-12 was worse (lower) in the case of women with Hyperactive Bladder symptoms and discomfort measured with the CACV questionnaire and in women with sexual dysfunction measured with FSM. PISQ-12 is an instrument with the appropriate psychometric characteristics to evaluate sexual function in women with pelvic floor problems.
