A new instrument to measure sexual function in women with urinary incontinence or pelvic organ prolapse.

OBJECTIVE

Our aim was to develop a condition-specific, reliable, validated, and self-administered instrument to evaluate sexual function in women with pelvic organ prolapse or urinary incontinence.

STUDY DESIGN

The questionnaire was designed after review of the literature and of nonspecific validated instruments. The study was completed in 2 phases. In phase 1 a total of 83 women completed both our questionnaire and the Incontinence Impact Questionnaire-7, with 20 women undergoing test-retest reliability analyses. Item analysis was based on the internal consistency, the correlations with the Incontinence Impact Questionnaire-7, the patient's age and self-rating of satisfaction, and the results of reliability testing. For final validation the questionnaire was administered in phase 2 to 99 women. Factor and item analyses were repeated, results were correlated with the Sexual History Form-12, and comparison was made between patients with high depression scores and those with low depression scores on the Symptom Questionnaire.

RESULTS

Factor analysis identified 3 domains, labeled Behavioral/Emotive, Physical, and Partner-Related. Sexual function scores were highly correlated with scores on the Sexual History Form-12 for the questionnaire (r = -0.74; P <.001) and for both the Behavioral/Emotive and the Partner-Related domains (r = -0.79 and -0.5, respectively; P <.001). The Physical domain was correlated with scores on the Incontinence Impact Questionnaire-7 (r = -0.63; P <.001). Women with high depression scores on the Symptom Questionnaire had significantly lower scores on the final questionnaire, in comparison with women without depression (P <.001).

CONCLUSION

We developed a condition-specific, validated, and reliable instrument, containing 31 items divided into 3 domains, to evaluate sexual functioning in women with urinary incontinence or pelvic organ prolapse.
