Development of a Japanese Version of the Daily Record of Severity of Problems for Diagnosing Premenstrual Syndrome

Abstract

Background: Premenstrual syndrome (PMS) causes physical and mental symptoms in women during the luteal phase of the menstruation cycle. To confirm the relationship between symptoms and the menstruation cycle, daily symptom records are essential for diagnosing PMS. The daily record of severity of problems (DRSP) is currently the most validated tool for tracking symptoms to confirm and scale the severity of PMS, but there has been no validated Japanese version of this instrument. We developed a Japanese version of the DRSP and assessed its psychometric properties. Methods: A Japanese version of the DRSP was developed following the translation guidelines of the latest Patient-Reported Outcomes Consortium. We conducted a computational psychometric study among 119 women, all of whom completed the Japanese version of the DRSP, the Center for Epidemiologic Studies Depression Scale (CES-D), the Premenstrual Dysphoric Disorder (PMDD) scale, and a Numerical Rating Scale (NRS) for general health status. Each was filled out twice, 2 weeks apart, so that one set was completed in the luteal phase. Results: The Japanese version of the DRSP was developed with translation and cultural adaptation. The internal consistency coefficient for the total score was 0.93. The DRSP in the luteal phase correlated highly with the CES-D, PMDD scale, and NRS for general health status. Conclusions: Our Japanese version of the DRSP, developed as a PMS/PMDD diagnostic tool, was shown to provide substantial validity and reliability to rate premenstrual symptoms for Japanese women.

The reliability and validity of the Japanese version of the Daily Record of Severity of Problems (J-DRSP) and Development of a Short-Form version (J-DRSP (SF)) to assess symptoms of premenstrual syndrome among Japanese women

“…This process comprised two independent forward translations, two independent back translations, a consensus meeting about content equivalence and cultural adaptation, reviews by other native Japanese healthcare providers, and cognitive interviews with patients with PMDD at Kyoto University. Internal consistency and concurrent validity were confirmed for 119 Japanese women using the Center for Epidemiologic Studies Depression Scale, PMDD Scale, and the Numerical Rating Scale for general health [8].…”

“…The Japanese version of the DRSP (J-DRSP) was developed in 2020 in accordance with the necessary translation and cultural adaptation guidelines published by the Patient-Reported Outcomes (PRO) Consortium [7,8]. This process comprised two independent forward translations, two independent back translations, a consensus meeting about content equivalence and cultural adaptation, reviews by other native Japanese healthcare providers, and cognitive interviews with patients with PMDD at Kyoto University.…”

“…The next necessary step in this process is to determine the factorial validity and test-retest reliability of the J-DRSP. In addition, development of a short-form of the J-DRSP would be ideal, as our previous study determined that the median time to complete the J-DRSP was 2 min, and both women with almost no premenstrual symptoms and those with very severe premenstrual symptoms complained that the use of the J-DRSP on a daily basis is cumbersome [8].…”

Psychometric Testing of the Japanese Version of the Daily Record of Severity of Problems Among Japanese Women

“…One Japanese version of the DRSP has been reported independently by another group. 27 They also reported the validity and reliability, but in their study the DRSP responses were not recorded daily but recorded only two days in the cycle (one day in the follicular phase and another day in the luteal phase). This study design was not in accordance with the usage of the original DRSP.…”
