Interpreting Premenstrual Symptoms Impact Survey scores using outcomes in health-related quality of life and sexual drive impact.

Objective: To link the Premenstrual Symptoms Impact Survey (PMSIS) scores to health-related quality of life (HRQOL) and sexual drive impact associated with premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD).
Study Design: Secondary data analysis was performed using the online survey study for PMSIS development. Women were sorted into 10 mutually exclusive score levels (N = 949). Their responses to the SF-12v2 Health Survey and the sexual drive question were dichotomized to indicate the presence of limitations/impairment. Chi-square analysis was conducted to compare the differences in percentages of women with limitations across 3 representative PMSIS score levels containing (1) women with no indication of PMS, (2) women at risk for PMS but not PMDD, and (3) women at risk for PMDD.
Results: The higher the PMSIS score level (more severe impact), the greater the percentage of women reported functional limitations. Women either at risk for PMS or PMDD were significantly more likely to report limitations than women with no indication of PMS in all HRQOL areas except for 2 Physical Functioning items and 1 Mental Health item and the General Health item. Significantly more women with PMS (67.5%) and with PMDD (73.3%) reported sexual drive impact than in women with no PMS (45.7%).
Conclusion: The associations between PMSIS score levels and the premenstrual symptoms' impact on HRQOL and sexual functioning assist the interpretation of PMSIS scores and use of the tool in reproductive-age women.
