To assess the validity and reliability of the Japanese version of the Daily Record of Severity of Problems (J-DRSP, 24 items) for evaluating symptoms of premenstrual syndrome (PMS), and to develop a short form version of the J-DRSP.
Using the "DRSP-JAPAN" smartphone app, we collected daily J-DRSP records from cycle day - 6 (CD - 6) to CD 10, with CD 1 representing the menstruation onset date. Factorial validity (exploratory factor analysis: EFA, confirmatory factor analysis: CFA) and criterion validity were examined, and test-retest reliability (intraclass correlation: ICC) evaluated. The short-form version of the J-DRSP was developed using classical test theory.
In total, 304 women participated and 243 recorded symptoms on at least 4 days spanning the week of the luteal phase (CD - 6 to CD 0) and 4 days spanning the week of the follicular phase (CD 4 to CD 10), with CD 0 set as the day before menstruation started. The EFA revealed a two-factor structure. Kaiser-Meyer-Olkin was 0.992, and Bartlett's test of sphericity chi-square was 3653.89 (P < 0.001). However, the model fitness of CFA was found to be suboptimal (comparative fit index (CFI): 0.83, root mean square error of approximation (RMSEA): 0.12). Total scores for J-DRSP and the sum scores for each subscale were higher on CD 0 than on CD 10 (p < 0.001), suggesting validity for some criteria. ICC values for the total J-DRSP score from CD 0 to CD - 1, and between CD 9 to CD 10, were 0.60 (95% CI: 0.48-0.72) and 0.76 (95% CI: 0.69-0.82), respectively. Having eliminated some original items after considering factor loading for each item, we developed an 8-item Short-Form J-DRSP (J-DRSP (SF)) comprising 2 factors (S-Psychological and S-Physical, 4 items for each). CFA showed a better model fit (CFI: 0.99, RMSEA: 0.048), and ICC values in the luteal and follicular phases were 0.61 (95%CI: 0.51-0.68) and 0.70 (95%CI: 0.62-0.77), respectively.
The J-DRSP has moderate to good reliability and a certain level of validity. The 8-item J-DRSP (SF) has a two-factor structure and can be used effectively among Japanese women to assess their PMS symptoms.
评估用于评估经前综合征（PMS）症状的日语版问题严重程度每日记录量表（J-DRSP，24项）的有效性和可靠性，并开发J-DRSP的简版。
使用“DRSP-JAPAN”智能手机应用程序，我们收集了从月经周期第-6天（CD -6）到第10天的每日J-DRSP记录，其中第1天代表月经开始日期。检验了因子效度（探索性因子分析：EFA，验证性因子分析：CFA）和效标效度，并评估了重测信度（组内相关系数：ICC）。使用经典测试理论开发了J-DRSP的简版。
共有304名女性参与，其中243名女性在黄体期（CD -6至CD 0）的至少4天以及卵泡期（CD 4至CD 10）的至少4天记录了症状，将CD 0设为月经开始前一天。EFA显示出两因素结构。Kaiser-Meyer-Olkin值为0.992，Bartlett球形检验卡方值为3653.89（P <0.001）。然而，发现CFA的模型拟合度欠佳（比较拟合指数（CFI）：0.83，近似均方根误差（RMSEA）：0.12）。J-DRSP的总分和每个子量表的得分在CD 0时高于CD 10时（p <0.001），表明对某些标准具有效度。从CD 0到CD -1以及CD 9到CD 10的J-DRSP总分的ICC值分别为0.60（95%CI：0.48 - 0.72）和0.76（95%CI：0.69 - 0.82）。在考虑每个项目的因子载荷后剔除了一些原始项目，我们开发了一个8项的简版J-DRSP（J-DRSP（SF）），包括2个因子（S-心理和S-生理，每个因子4项）。CFA显示出更好的模型拟合（CFI：0.99，RMSEA：0.048），黄体期和卵泡期的ICC值分别为0.61（95%CI：0.51 - 0.68）和0.70（95%CI：0.62 - 0.77）。
J-DRSP具有中等至良好的可靠性和一定程度的有效性。8项的J-DRSP（SF）具有两因素结构，可有效地用于日本女性评估其PMS症状。
