Translation and validation of the Korean version of acute cystitis symptom score.

PURPOSE: Acute Cystitis Symptom Score (ACSS) is a simple self-reporting questionnaire initially developed in Uzbek language to help diagnose acute uncomplicated cystitis (AUC). The purpose of this study was to translate the ACSS to Korean and validate the Korean version of ACSS using Korean-speaking women. MATERIALS AND METHODS: The original version of ACSS in Uzbek was translated into the target (Korean) version according to internationally accepted guidelines for the translation and cultural adaptation. Cognitive interviews were then conducted for five women with symptoms of AUC and five women without AUC who were native speakers of the Korean language to investigate the clarity, understandability, and acceptability of the translation. The final Korean version of the ACSS was tested in 50 women (31 AUC patients and 19 controls) for clinical validation. RESULTS: Reliability test for 9 questions (6 questions about typical symptoms of AUC, and 3 questions on quality of life) showed high values (Cronbach's alpha=0.853). The sum score of typical symptoms showed the highest balance for diagnostic sensitivity and specificity (area under the ROC curve=0.935). Sensitivity and specificity to predict AUC were 90.3% and 89.5% at cut-off score 6 of the typical domain. CONCLUSIONS: The Korean version of the ACSS showed high levels of reliability and validity, similar to other validated versions in different languages. It will play an important role in practice and/or clinical research for diagnosis and treatment efficacy monitoring of Korean-speaking women suffering from AUC.

Clinical Validation of the Greek Version of the Acute Cystitis Symptom Score (ACSS)-Part II.

The Acute Cystitis Symptom Score (ACSS) is a patient self-reporting questionnaire for the clinical diagnosis and patient-reported outcome (PRO) in women with acute uncomplicated cystitis (AC). The aim of the current study (part II) is the clinical validation of the Greek ACSS questionnaire. After linguistic validation according to internationally accepted guidelines and cognitive assessment (part I), the clinical validation was performed by using the Greek ACSS study version in 92 evaluable female participants including 53 patients with symptoms suspicious of AC and 39 controls. The clinical outcome using the ACSS questionnaire at different points in time after the start of treatment was demonstrated as well. The age (mean ± SD) of the 53 patients (44.7 ± 17.0 years) and 39 controls (49.3 ± 15.9 years) and their additional conditions at baseline visits, such as menstruation, premenstrual syndrome, pregnancy, menopause, diabetes mellitus, were comparable. There was, however, a significant difference (p < 0.001) between patients and controls at baseline visit regarding sum score of the ACSS domains, such as typical symptoms and quality of life. The clinical outcome of up to 7 days showed a fast reduction of the symptom scores and improvement of quality of life. The optimal thresholds for the patient-reported outcome of successful therapy could be established. The linguistically and clinically validated Greek ACSS questionnaire can now be used for clinical or epidemiological studies and also for patients' self-diagnosis of AC and as a PRO measure tool.
