The Taiwanese Depression Questionnaire (TDQ) is a new, culturally relevant tool for screening depression in Taiwan. It demonstrates high reliability and validity for use in local communities.
Area of Science:
- Psychiatry
- Psychometrics
- Epidemiology
Background:
- Western depression scales have limitations due to cultural differences in emotional expression.
- A culturally relevant screening tool is needed for Taiwanese society.
Purpose of the Study:
- To develop and validate the Taiwanese Depression Questionnaire (TDQ).
- To create a culturally relevant depression screening tool for epidemiological surveys in Taiwan.
Main Methods:
- A 20-item draft was developed and refined to an 18-item version.
- The TDQ underwent testing for concurrent validity, internal consistency, and reliability.
- Receiver operating characteristic (ROC) curve analysis was performed on community subjects.
Main Results:
- The 18-item TDQ showed satisfactory Cronbach's alpha (0.90) and ROC area (0.92).
- Sensitivity was 0.89 and specificity was 0.92 at a cutoff score of 19.
Conclusions:
- The TDQ is a culturally relevant and adaptable questionnaire.
- It is suitable for screening depressive individuals in Taiwanese local communities.
