Initial report of the cancer Patient-Reported Outcomes Measurement Information System (PROMIS) sexual function committee: review of sexual function measures and domains used in oncology.

For this report, the authors described the initial activities of the Cancer Patient-Reported Outcomes Measurement Information System (PROMIS)-Sexual Function domain group, which is part of the National Institutes of Health Roadmap Initiative to develop brief questionnaires or individually tailored assessments of quality-of-life domains. Presented are a literature review of sexual function measures used in cancer populations and descriptions of the domains found in those measures. By using a consensus-driven approach, an electronic bibliographic search was conducted for articles that were published from 1991 to 2007, and 486 articles were identified for in-depth review. In total, 257 articles reported the administration of a psychometrically evaluated sexual function measure to individuals who were diagnosed with cancer. Apart from the University of California-Los Angeles Prostate Cancer Index, the International Index of Erectile Function, and the Female Sexual Function Index, the 31 identified measures have not been tested widely in cancer populations. Most measures were multidimensional and included domains related to the sexual response cycle and to general sexual satisfaction. The current review supports the need for a flexible, psychometrically robust measure of sexual function for use in oncology settings and strongly justifies the development of the PROMIS-Sexual Function instrument. When the PROMIS-Sexual Function instrument is available publicly, cancer clinicians and researchers will have another measure with which to assess patient-reported sexual function outcomes in addition to the few legacy measures that were identified through this review.
