Background: Depression is a widespread and incapacitating mental health disorder that impacts millions of people worldwide, playing a substantial role in the overall global health challenges. Depression has a big impact on a person’s quality of life, cognitive and social functioning, risk of suicide, risk of heart disease and other illnesses, as well as death from all causes. . Objective: Objective: It may be challenging to choose the best tools to screen for severe depression in patients with recurrent depression disorder (PRD) considering the diversity of psychological scales in Vietnam. The aim of this study was to evaluate diagnostic value for detect severe depression of four psychological scales including Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), Beck Depression Inventory Scale (BECK), and Zung’s Self-Rating Anxiety Scale (SAS) by genders and age groups among PRD in Vietnam. Methods: This study was conducted at National Institute of Mental Health, Bach Mai Hospital, Vietnam, from 2020 to 2021. There were 109 PRD evaluated with HAM-D, HAM-A, BECK, and SAS by qualified psychiatrists. By analysing Area Under the Curve (AUC) of Receiver Operating Characteristic (ROC) curve, we determined sensitivity, specificity and cut points of four above scales.Results: Among four scales, the BECK scale had the best diagnostic effect with the most optimal sensitivity and specificity (61.64% and 75%, respectively). We proposed the new cut-off of HAM-D, HAM-A, BECK, and SAS for detecting severe depression among PRD were 20, 34, 30, and 45, respectively. By genders, the cut points for the HAM-D, HAM-A, BECK, and SAS in males were 20, 27, 34, and 44, respectively, while those figure in females were 14, 34, 30, and 46, respectively. By age groups, adults had cut values for four above scales of 20, 34, 27, and 45, respectively, whereas those for the elderly were 16, 17, 35, and 44, respectively. Conclusion: We highly recommended that BECK is the most optimal method to screen severe depression in PRD in Vietnam. It is essential to utilize varied cut values of HAM-D, HAM-A, BECK, and SAS for different genders and age groups.
