Is the Turkish version of the PMS-IQ questionnaire reliable for measuring PMS?
Yes. The Turkish PMS-IQ questionnaire is reliable and measures what it should measure in Turkish women with PMS. However, it has only been tested in Turkey.
What they did
Researchers tested a questionnaire called the PMS-IQ in 146 Turkish women with PMS. They asked 96 of these women to complete it again one week later to check if answers were consistent. They also compared results to other existing PMS questionnaires.
What they found
The questionnaire showed good reliability (test-retest scores from 0.755 to 0.847). It correlated well with other PMS measures (0.718 with PMSS and 0.774 with PMSIS), meaning it measured the same things. It did not correlate with personality questionnaires, as expected. The questionnaire had three main parts.
What it means for you
The Turkish PMS-IQ questionnaire works well for measuring how severe a woman's PMS is. Doctors could use it to track PMS over time. The main limit is it was only tested in Turkey and only in women already diagnosed with PMS, so we don't know if it works in other countries or for new diagnoses.

Original abstract
Background: Short and practical questionnaires and tests that assess premenstrual symptoms and premenstrual syndrome (PMS) are required. Objectives: This study aimed to investigate the cross-cultural adaptation, validity, and reliability of the Premenstrual Syndrome Impact Questionnaire (PMS-IQ) in Turkish women with PMS. Design and setting: The reliability and validity of the questionnaire were evaluated in Tokat, Türkiye. Methods: A convenience sample of 146 individuals diagnosed with PMS was used to assess the reliability and validity of the Turkish version of the PMS-IQ. Test-retest analyses were performed in a subset of 96 individuals one week after the initial assessment. Construct validity was evaluated through convergent validity analysis using the Premenstrual Syndrome Scale (PMSS) and the Premenstrual Symptoms Impact Survey (PMSIS), and divergent validity analysis with the Big Five Inventory-10 (BFI-10). Results: Cronbach's α values for the total score and subscales ranged from 0.861 to 0.917, whereas the test-retest reliability values ranged from 0.755 to 0.847. Factor analysis indicated that the scale had a three-factor structure. The total PMS-IQ score was significantly correlated with both the PMSS (r = 0.718) and PMSIS (r = 0.774), but showed no significant correlation with the BFI-10 (r = 0.113). No floor or ceiling effects were observed for the total or subscale scores of the PMS-IQ. Conclusions: The Turkish version of the PMS-IQ demonstrated reliability and validity for evaluating individuals with PMS. Clinical trial registration: This study is registered at ClinicalTrials.gov (identifier: NCT05725447).
