Development of the Blood Stasis Questionnaire for Gynecological Diseases: An Analytical Cross-Sectional Study

Area of Science:

• Integrative Medicine
• Gynecology
• Medical Diagnostics

Background:

• Blood stasis, characterized by slowed or stagnant blood flow, is linked to various metabolic, musculoskeletal, and gynecological diseases.
• Existing questionnaires (BSQ-I and BSQ-II) provided a foundation for developing a specialized tool for gynecological applications.

Purpose of the Study:

• To develop and validate the Blood Stasis Questionnaire for Gynecological Disease (BSQ-GD).
• To assess the reliability and diagnostic accuracy of the BSQ-GD in identifying blood stasis in women with gynecological conditions.

Main Methods:

• The BSQ-GD was developed using clinical indicators from BSQ-I and BSQ-II.
• 103 women (25-65 years) with gynecological diseases were enrolled in a cross-sectional study.
• Reliability was assessed using Cronbach's alpha; validity was confirmed through correlation and discriminant analyses. Logistic regression determined prediction accuracy and cut-off values.

Main Results:

• The BSQ-GD demonstrated satisfactory internal consistency (Cronbach's α = 0.71) and validity.
• Significant differences in scores were observed between blood stasis (22.30 ± 3.34) and non-blood stasis (14.93 ± 3.49) groups.
• The optimal cut-off score was 19, with high diagnostic accuracy (AUC ~96%), sensitivity (80.95%), and specificity (92.50%).

Conclusions:

• The BSQ-GD is a suitable instrument for estimating blood stasis in patients with gynecological diseases.
• The questionnaire exhibits high diagnostic sensitivity when utilizing the established cut-off value.
