Cut-Off Value and Validation of Mind-In (Vibraimage) Technology for Depression Screening in Primary Care

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 27.4-28.2for 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.
