Psychometric properties of the Turkish version of the Menstrual Distress Questionnaire

Abstract

Purpose: The Menstrual Distress Questionnaire (MEDI-Q) is a new, reliable, and valid instrument developed in Italy to assess menstrual distress. The aim of the current study was to assess the psychometric properties of the MEDI-Q. Methods: MEDI-Q was translated into Turkish according to Beaton’s recommendations. 234 patients (mean age, 31 years; range, 19–50 years) were recruited for the study. The test– retest reliability was evaluated in 44 women after an interval of two weeks. Cronbach's alpha was used to verify the internal consistency while the test-retest reliability was estimated using the intraclass correlation coefficient (ICC). Construct validity was analyzed using Pearson’s correlation analysis to compare with the Brief Symptom Inventory (BSI). Floor and ceiling effects were also evaluated. Results: The Turkish version of the MEDI-Q demonstrated acceptable internal consistency (Cronbach's alpha, 0.82) and testretest reliability (ICC = 0.89). No significant correlations were found between age and the MEDI-Q total score or its subscales (p>0.05). Positive significant correlations were identified between the BSI-Global Severity Index, BSI-Positive Symptom Total, and BSI-Positive Symptom Distress Index with the MEDI-Q total score (r=0.207, p=0.001; r=0.229, p=0.000; r=0.176, p=0.007, respectively). The MEDI-Q score and BSI scores showed significant correlation, indicating construct validity. There were no floor and ceiling effects were found. Conclusion: The Turkish version of the MEDI-Q is reliable and valid for assessing menstruation distress in women whose native language is Turkish.

Menstrüel Sıkıntı Anketi’nin Türkçe versiyonunun psikometrik özellikleri

Abstract

Amaç: Menstrüel Sıkıntı Anketi (MEDI-Q), menstrüel sıkıntıyı değerlendirmek için İtalya'da geliştirilmiş yeni, güvenilir ve geçerli bir araçtır. Bu çalışmanın amacı MEDI-Q'nun psikometrik özelliklerini değerlendirmekti. Yöntem: MEDI-Q Beaton'ın önerileri doğrultusunda Türkçeye çevrildi. 234 hasta (ort. yaş:, 31 yaş aralığı;19-50 ) çalışmaya alındı. Test-tekrar test güvenilirliği iki hafta aradan sonra 44 kadında değerlendirildi. İç tutarlılık Cronbach alfa kullanılarak test edilirken, test-tekrar test güvenilirliği ise sınıf içi korelasyon katsayısı (intraclass correlation coefficient, ICC) kullanılarak hesaplandı. Yapı geçerliliği, Kısa Semptom Envanteri ile karşılaştırmak için Pearson korelasyon analizi kullanılarak analiz edildi. Ayrıca taban ve tavan etkileri de değerlendirildi. Bulgular: MEDI-Q'nun Türkçe versiyonu kabul edilebilir iç tutarlılık (Cronbach's alpha, 0.82) ve test-tekrar test güvenilirliği (ICC= 0.89) gösterdi. Yaş ile MEDI-Q toplam puanı ve alt ölçekleri arasında anlamlı bir ilişki olmadığı bulundu (p>0,05). BSI-Global Şiddet İndeksi, BSI-Pozitif Semptom Toplamı ve BSI-Pozitif Semptom Sıkıntı İndeksi ile MEDI-Q toplam puanı arasında pozitif yönde anlamlı korelasyonlar tespit edildi (r=0,207, p=0,001; r=0,229, p=0,000; r=0,176, p=0,007, sırasıyla). Yapı geçerliliğinde MEDI-Q skoru ve KSE skorları arasında anlamlı korelasyon bulundu. Herhangi bir taban ya da tavan etkisi görülmedi. Sonuç: Kadınlarda menstruasyon sıkıntısını değerlendirmede MEDI-Q’nun Türkçe versiyonu güvenilir ve geçerlidir.
