The objective of the current study was to translate and test psychometric properties of the Premenstrual Symptoms Screening Tool (PSST) in Iran. Using a standard "forward-backward" procedure, the English version of PSST was translated into Persian. A random sample of university students aged 18 years and over completed the questionnaire in Tehran, Iran. Psychometric properties of the Iranian version of PSST were assessed by performing reliability (internal consistency) and validity analyses [Content Validity Ratio (CVR) and Content Validity Index (CVI)]. In all, 925 female students took part in the study. Of these, 284 (30.7 %) had premenstrual syndrome (PMS) and 119 (12.9 %) had premenstrual dysphoric disorder (PMDD). Reliability of the PSST as measured by internal consistency was found to be satisfactory (Cronbach's alpha coefficient, 0.93). The content validity as assessed by CVR and CVI were desirable (0.7 and 0.8, respectively). The Iranian version of PSST seems to be a reliable and valid measure of detecting PMS and PMDD in Iranian young female populations.
本研究的目的是在伊朗将经前症状筛查工具（PSST）翻译并测试其心理计量学特性。通过标准的“前后”程序，将 PSST 的英文版本翻译为波斯语。在伊朗德黑兰，随机抽取了 18 岁及以上的大学生样本完成了问卷。通过可靠性（内部一致性）和有效性分析[内容效度比（CVR）和内容效度指数（CVI）]来评估 PSST 伊朗版本的心理计量学特性。共有 925 名女学生参加了这项研究。其中，284 名（30.7%）患有经前综合征（PMS），119 名（12.9%）患有经前烦躁障碍（PMDD）。通过内部一致性测量发现 PSST 的可靠性令人满意（Cronbach's alpha 系数为 0.93）。内容效度评估的 CVR 和 CVI 分别为 0.7 和 0.8，均为理想值。PSST 的伊朗版本似乎是一种可靠且有效的工具，可用于检测伊朗年轻女性人群中的 PMS 和 PMDD。
