일차의료에서 우울증 선별도구로서 마인드인(바이브라이미지)의 절사값 및 유효성 = Cut-Off Value and Validation of Mind-In (Vibraimage) Technology for Depression Screening in Primary Care

다국어 초록 (Multilingual Abstract)

Background: The prevalence of depression and depressive symptoms is increasing worldwide, notably in Korea. However, depression is often underdiagnosed and undertreated in primary care settings. This study was intended to determine the cut-off values and validity of Mind-in (Vibraimage) technology for detecting depression among patients visiting the Department of Family Medicine at a hospital in Seoul.
Methods: The study’s sample consisted of 100 adults aged 19–79 who visited the Family Medicine Department of a hospital in Seoul between August 1, 2021, and July 31, 2022. Participants completed questionnaires and underwent Mind-in (Vibraimage) treatment. Cut-off values, sensitivity, specificity, the area under the curve with 95% confidence intervals, and diagnostic performance were evaluated using receiver operating characteristic curve analysis, maxstat, and rpart methods.
Results: Study participants consisted of 43 male and 57 female. The optimal cut-off value for depressive symptoms was 27.4–28.2 for negative mood and 50.0–50.1 for happiness index. For antidepressant medication users, the cut-off values for depressive symptoms were 27.4–32.4 and 46.3–50.6 for the happiness index. The sensitivity and specificity of negative mood were 0.33 and 0.84–0.87, respectively, while for the happiness index, they were 0.89 and 0.33–0.34, respectively.
Conclusion: This study identified the cut-off values of Mind-in (Vibraimage) technology for screening depression in primary care settings. Further largescale multicenter studies are needed to validate and refine these values for broader clinical application.
