Abstract
BACKGROUND: Major Depressive Disorder (MDD) can occur in patients with tuberculosis. The purpose of this research was to develop an early detection system for MDD and conduct an accuracy test. METHODS: The MOODMIND application uses Natural Language Processing (NLP) with sentiment analysis techniques. MOODMIND offers both speech and text options and is available in Indonesian/English. The screening results were compared with physician clinical interview. Single blinding was used so that doctor was unaware of the application test. RESULTS: The app asks open- and closed-ended questions for MDD identification based on the DSM-5. The test results were divided into non-depressive (none or at-risk) and suspected depression groups. Among the 21 subjects, MOODMIND showed 67% (95% CI: 9.4-99.2%) sensitivity and 100% (95% CI: 81.5-100%) specificity. CONCLUSIONS: MOODMIND demonstrated accuracy results in pilot study but required advanced research with more sample and diverse settings. Ease is advantageous because the steps are simple, but it can be improved by adding words related to depression in the lexicon adjustment for increasing diagnostic performance.
