BACKGROUND: Adequate data are required to assess the validity of mental-emotional disorder for symptoms of depression based on Indonesia National Health Survey (NHS).

AIM: This study aims to assess the validity of mental-emotional disorder using self-reporting questionnaire-20 (SRQ-20) to the symptoms of depression evaluated through the means of a Mini-International Neuropsychiatric Interview (MINI) questionnaire.

METHODS: The data were obtained from a total sample of 555,066 subjects analyzed from the NHS in 2018. These subjects were at least 15 years old with their mental-emotional disorders and symptoms of depression assessed using the self-reporting questionnaire (SRQ) and MINI, respectively. This study used the calculation of sensitivity, specificity, positive and negative predictive value, likelihood ratio, receiver operating characteristic, kappa Brennan, and Prediger with the STATA version 15.00 to analyze the data.

RESULTS: The cutoff point in each group was different, ranging from 4 to 6 that almost all the area under curve values were above 0.90 and the SRQ agreement with MINI depression is good because they all have values above 0.80.

CONCLUSION: The results obtained are used as material to predict the rate of symptoms depression in Indonesian residents aged ≥15 years.
