The Modified Rush Sexual Inventory: preliminary psychometric findings.

Sexual dysfunction associated with psychiatric disorders and the treatment of these disorders can impede a patient's optimal recovery and quality of life. Patients are typically reluctant to report their sexual difficulties. Therefore, self-report measures that comprehensively and concisely assess sexual difficulties are a beneficial contribution to clinical research and practice. The Modified Rush Sexual Inventory (MRSI) not only assesses sexual functioning and satisfaction using a multiple-choice format, but it also includes an introductory section for patients' medical histories and free responses. Though the MRSI has been used in clinical trial research, the reliability and validity of the measure is unknown. This study presents the initial reliability and validity findings of the MRSI.
