In order for a measure to reliably evaluate treatment efficacy, it is important that the measure used has adequate responsiveness. However, the responsiveness of the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire, a highly recommended questionnaire by the International Consultation of Incontinence to assess sexual function in patients with incontinence, has not been established. To enable the use of GRISS to measure change in sexual function following incontinence treatment, we evaluated the short- and long-term responsiveness of the GRISS in couples with female stress urinary incontinence partners.
Forty-eight couples with female stress urinary incontinence partners were included in the study. The GRISS, a 28-item multidimensional measure, comprises two sets of questionnaires to assess sexual function in both male and female partners. Responsiveness was investigated using data from our recent randomized controlled trials evaluating efficacy of pulsed magnetic stimulation for treatment of female patients with stress urinary incontinence. Effect size index and standardized response mean were used to measure responsiveness of the English and Chinese versions of GRISS.
For short-term responsiveness, the overall female and male GRISS scores had effect sizes and standardized response means ranging from 0.60 to 0.83 and 0.44 to 0.78 respectively. For long-term responsiveness, the overall female and male GRISS scores had effect sizes and standardized response means ranging from 0.59 to 0.77 and 0.48 to 0.79 respectively.
In conclusion, the English and Chinese versions of GRISS had adequate responsiveness for use in couples with incontinent partners. The GRISS can be a useful measure to detect change in sexual function of couples following treatment of females with stress urinary incontinence.
