Abstract

Background

The Dysmenorrhea Symptom Interference (DSI) scale is a reliable, valid, and responsive tool to assess the interference of menstrual pain in the physical, mental, and social activities of women.

Objective

To translate and cross-culturally adapt the DSI scale into Brazilian-Portuguese (DSI-BrPt) and investigate the measurement properties of this version in on- and off-menses versions.

Methods

The original (United States) scale was translated and culturally adapted following existing guidelines. Measurement properties of the DSI-BrPt were investigated in 1387 women with dysmenorrhea. Reliability was analyzed via intraclass correlation coefficients (ICC) and test-retest reliability. Furthermore, structural validity, internal consistency (Cronbach's alpha), cross-cultural validity, construct validity (correlation with WHODAS 2.0 and SPS-6 scores questionnaires), and floor and ceiling effects were determined.

Results

No significant adaptations were needed during the translation process of the DSI-BrPt. The values of Cronbach's α were adequate (α ≥0.87) for the unidimensional scale. The test-retest reliability was considered adequate (ICC >0.78) and there was no systematic error for both on-menses and off-menses versions. Moreover, the DSI had a positive and strong correlation with WHODAS 2.0. There were no floor and ceiling effects neither for the total sample, nor among off-menses, or on-menses women.

Conclusion

The DSI-BrPt scale has been translated and cross-culturally adapted successfully. The DSI-BrPt scale presented adequate measurement properties. The scale is valid and reliable, and, therefore, an adequate tool for monitoring dysmenorrhea symptoms in Brazilian women during and between menses.

巴西版痛经症状干扰（DSI）量表的翻译、跨文化适应性和测量特性

背景痛经症状干扰（DSI）量表是一种可靠、有效、反应灵敏的工具，用于评估痛经对女性生理、心理和社交活动的干扰。方法根据现有指南对原始（美国）量表进行了翻译和文化适应性调整。在 1387 名痛经妇女中调查了 DSI-BrPt 的测量特性。通过类内相关系数（ICC）和测试-再测可靠性分析了信度。此外，还确定了结构效度、内部一致性（Cronbach's α）、跨文化效度、构架效度（与 WHODAS 2.0 和 SPS-6 评分问卷的相关性）以及下限效应和上限效应。测试-重测信度被认为是适当的（ICC >0.78），并且在犯罪和非犯罪版本中都没有系统误差。此外，DSI 与 WHODAS 2.0 有着很强的正相关。结论DSI-BrPt量表已被成功翻译并进行了跨文化调整。DSI-BrPt 量表具有充分的测量属性。该量表有效且可靠，因此是监测巴西妇女经期和两次月经之间痛经症状的适当工具。
