Clinical Trial Summary

This study will explore the specific response characteristics of the niacin skin response test in the population with depressive disorder malinger. The investigators expect that depressive disorder malinger can be discriminated by the niacin skin reaction test.

Description:

Depressive disorder malingers are prevalent, and it is difficult to recognize. As an objective and scientific endophenotype of depressive disorders, the blunted features in NSRT are determined by genetic factors and are not influenced by the mental state of individual subjects at a particular moment, which can provide a reliable retrospective biological index for the determination of mental and psychological state of depressive disorder malinger. This study will explore the specific response characteristics of the niacin skin response test in the population with depressive disorder malinger, explore the application prospects of this technology in the field of biological identification, and establish a high-specificity biological diagnostic model for depressive disorder malinger and validate and optimize it, so as to provide a biological basis for the accurate and efficient identification of depressive disorder malingers using objective indexes in the process of clinical practice.

Intervention

Diagnostic Test:
• Niacin skin reaction test
Nicotinic skin reaction, also known as nicotinic flush reaction, occurs when a solution of nicotinic acid methyl ester briefly contacts the skin. Following penetration through the skin barrier into the subcutaneous tissue, it generates nicotinic acid (vitamin B3). Under the action of phospholipase A2 (PLA2), cyclooxygenase (COX), and other enzymes, arachidonic acid (AA) on the cell membrane is cleaved to produce prostaglandins, leading to local vasodilation, increased blood perfusion, and the transient appearance of erythema on the skin.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Niacin reaction test	Total niacin reaction score: It includes one value (Total Area), which refers to the sum of nicotinic acid reaction areas for each concentration (a total of 360) collected within 10 minutes from 60 images.; Total single point score for niacin reaction: It includes six values, each representing the sum of nicotinic acid reaction areas for individual concentrations (a total of 360) collected within 10 minutes from 60 images.; Niacin reaction speed: It includes one value (EC50), representing the time required for the nicotinic acid reaction of the first concentration to reach half of the plateau phase.; Niacin flush color: It includes one value (Total Color), which refers to the color value of 6 flush areas in the images captured at the 10th minute.	During the intervention
Secondary	Model specificity and sensitivity	Evaluate the effectiveness of the classification model in identifying feigned depression patients through measures such as the area under curve (AUC), sensitivity (Sen), specificity (Sep), positive predictive value (PPV), and negative predictive value (NPV), where higher AUC, Sen, Sep, PPV, and NPV values indicate better classification performance of the model.	Through study completion, an average of 2 years
Secondary	The F Scale in Minnesota Multiphasic Personality Inventory	The F Scale in Minnesota Multiphasic Personality Inventory (MMPI) is used to detect attempts at fraud.	Baseline, pre-intervention
