Introduction and hypothesis
We sought to develop a Spanish translation of the Female Genitourinary Pain Index (GUPI) and to validate this instrument in US Latina women.
Methods
Translation back-translation was performed to create the initial Spanish version. Bilingual women with pelvic and/or genitourinary pain were recruited from clinical sites and social media. Participants reported demographics and completed the Female GUPI in both English and Spanish. Agreement was assessed for each item, subscale and total score. Additionally, we performed cognitive debriefing interviews to further test face validity. A consensus group of bilingual physicians and healthcare personnel utilized comments from the interviews to create a final Spanish version.
Results
Thirty-four participants completed the questionnaire. Their average age was 33 years, 80% reported attending some college, and 20% reported an undergraduate degree or higher. Most were born in mainland USA (57%) or Mexico (27%). Agreement for the pain, urinary and quality of life subscales between the English and Spanish versions of the measure were excellent (0.91, 0.89 and 0.92, respectively) with 0.96 agreement for the measure as a whole. Despite favorable psychometrics, preferences for alternate wording were reported over 50 times. Based on that feedback, a consensus group was formed, which recommended changes to 13 of the 15 items, 3 of which required complete rewriting.
Conclusions
The Spanish Female GUPI is strongly correlated with the English original; however, participants reported the language was overly complex. Translation and validation should include review of the measure and feedback by the target audience for optimal clarity and readability.
