Systematic review, 2025 # Which patient-reported tools accurately measure PMS and PMDD in Japanese? Some tools like the New Short-Form Premenstrual Symptoms Questionnaire and Japanese Daily Record of Severity of Problems showed good structural validity and internal consistency. However, most tools need further validation research. Strong study design Studies of PMS and PMDD assessment tools used in Japan (13 studies of 11 unique tools) ## What they did Systematic review of 13 studies evaluating 12 versions of 11 unique patient-reported outcome measures for assessing PMS and PMDD in Japan. The review searched MEDLINE, CINAHL, Cochrane Library, and Ichushi-Web databases. COSMIN methodology was used to assess measurement quality. ## What they found 9 tools were recall-based and 4 were daily recording scales. Most scales showed good structural validity and internal consistency. Evidence was limited for reliability, criterion validity, and construct validity. None of the scales reported all psychometric properties outlined by COSMIN. ## What it means for you Several Japanese assessment tools for PMS and PMDD show promise but need more validation research. The field needs development of new, more rigorous tools. Main limitation: this review focused on Japanese tools only. 13 studies reviewed 11 unique measurement tools 9 recall-based scales ## About the study Original title Psychometric properties of patient-reported outcome measures to assess premenstrual syndrome/premenstrual dysphoric disorder in japanese: a systematic review using the COSMIN methodology Authors Tsuyuki K, Egawa M, Ohsuga T et al.

This systematic review evaluated the psychometric properties of PROMs used to assess PMS/PMDD in Japan. Methodology: A systematic literature search was conducted in the MEDLINE, CINAHL, Cochrane Library, and Ichushi-Web databases. The COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology was used to assess the methodological quality and measurement properties of the included PROMs. Results: A total of 13 studies that evaluated 12 versions of 11 unique PROMs were included. PROMs were categorized as recall-based (n = 9, 69%) or daily recording scales (n = 4, 31%). The structural validity and internal consistency were relatively well evaluated for most scales. However, evidence was limited for other measurement properties such as reliability, criterion validity, and construct validity. None of the scales reported all psychometric properties outlined by COSMIN. The New Short-Form of the Premenstrual Symptoms Questionnaire and the Japanese version of the Daily Record of Severity of Problems demonstrated sufficient structural validity and internal consistency, although the quality of evidence for other properties was indeterminate. Conclusions: Although some PROMs demonstrated promising psychometric properties, further validation studies are required for most scales. The development of innovative scales with robust measurement properties is essential for advancing the assessment of PMS/PMDD in Japanese clinical and research settings. Careful consideration of the characteristics of each PROM is necessary when selecting instruments for specific purposes.
