Abstract
Aim
To translate and validate the Chinese version of the MDASI-THY among thyroid cancer patients.
Background
The M.D. Anderson Symptom Inventory-Thyroid Cancer module (MDASI-THY) is one of well-validated instruments for thyroid-specific symptom assessment. To date, the instrument has not been used in China.
Methods
After standard forward- and back-translation procedures, two instruments, the Chinese version of MDASI-THY and the European Organization for Research and Treatment of Cancer QLQ C30, were answered by 309 thyroid patients. The content, convergent discriminant validity and reliability of the MDASI-THY were evaluated. The Standards for Reporting Diagnostic Accuracy Studies (STARD) was used as reporting checklist.
Results
S-CVI and I-CVI of the instrument were over 0.80. There were significant relationships between MDASI-THY and EORTC QLQ-C30 (p<0.001). Symptoms were severer for patients underwent surgical treatment. The Cronbach’s alpha was 0.966 (between 0.954 and 0.827 for subscales). Most symptom items had moderate to high interitem correlations.
Conclusions
The Chinese version of MDASI-THY demonstrated favorable validity and reliability. It can be used in development of symptom management program in thyroid cancer patients in China.
Relevance to clinical practice:
Nurse can apply this instrument to assess Chinese thyroid cancer patients to increase the understanding of their symptom experience, resulting in a better symptom management.
