Quality of patient-reported outcome measures for primary dysmenorrhea: a systematic review.

PURPOSE

To conduct a systematic review of the quality of patient-reported outcome measures (PROMs) for primary dysmenorrhea (PDys) using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology, and to derive recommendations for use of the PROMs.

METHODS

We searched PubMed and Web of Science for studies reporting on the development and/or validation of any PROMs for women with PDys. Applying the COSMIN Risk of Bias Checklist, we assessed the methodological quality of each included study. We further evaluated the quality of measurement properties per PROM and study according to the criteria for good measurement properties, and graded the evidence. Based on the overall evidence, we derived recommendations for the use of the included PROMs.

RESULTS

Data from seven studies reporting on four PROMs addressing different outcomes were included. Among those, the Adolescent Dysmenorrhic Self-Care Scale (ADSCS) and the on-menses version of the Dysmenorrhea Symptom Interference Scale (DSI) can be recommended for use. The Exercise of Self-Care Agency Scale (ESCAS) and the Dysmenorrhea Daily Diary (DysDD) have the potential to be recommended for use, but require further validation. The off-menses version of the DSI cannot be recommended for use.

CONCLUSIONS

The ADSCS can be recommended for the assessment of self-care behavior in PDys. Regarding measures of impact, the on-menses version of the DSI is a suitable tool. Covering the broadest spectrum of outcomes, the DysDD is promising for use in medical care and research, encouraging further investigations. Further validation studies are indicated for all included PROMs.
