Patients with chronic diseases, such as tuberculosis, can quickly become depressed. To detect depression in Tuberculosis patients, a valid and reliable instrument is needed. Since so many Indonesians are unable to read the English edition, the Indonesian language version of the Zung Self-Rating Depression Scale questionnaire must be proven as a credible and accurate instrument.

The aim of this study is to find out whether the Indonesian language version of the Zung Self-Rating Depression Scale questionnaire is accurate and reliable.

Methods: A cross-sectional study was conducted in which pulmonary tuberculosis patients were given the Zung Self-Rating Depression Scale questionnaire, which had been translated into Indonesian. The population’s characteristics were presented as mean, standard deviation, and percentage. For the validity test, a Corrected Item-Total Correlation table was used, and the reliability test result was presented as a Cronbach’s Alpha value.

The population in this study has an average age of 47.75 8.44 years. The majority of them have married (93 percent ). 69 percent of male and female pulmonary tuberculosis patients have only completed elementary school, while 33% have only completed high school. Since the Corrected Item-Total Correlation values for all 20 questions are greater than r table (>0,195), they are all true. The questionnaire is also accurate, with a r Alpha value of 0.887, which is higher than the r table value (>0,195).
