Description
Technical Field
The invention relates to the technical field of depression screening, in particular to a standardized group depression risk screening system and method based on a habit removal and film viewing task.
Background
Depression is one of the most common mood disorders, characterized primarily by a persistent depression in mood, a significant reduction in interest or enjoyment of all or nearly all activity, insomnia or hypersomnia, and impairment in cognitive function, among others. About 2.8 million depressed patients are currently worldwide reported by the World Health Organization (WHO), accounting for about 3.8% of the world's general population. Depression is different from what people often say as mood swings or negative emotional reactions under stress for a short time, and moderate and severe depression is very dangerous to the health of patients, and can significantly affect their daily work, learning and home functions. Therefore, the method accurately identifies and screens the individuals with high risk of depression, and is an important premise for avoiding the influence of depression on physical and mental health and life safety of patients by performing early intervention later.
While there are many methods of treating depression that have proven effective, there are still difficulties in diagnosing depression. The "gold standard" of current clinical depression diagnosis is the structured interview assessment of individuals by professionally trained doctors using content in mental disease diagnostic manuals such as DSM-IV, DSM-V, ICD-10, etc. However, this assessment is difficult to apply to large scale screening for risk of depression due to the long time consuming, specialized training, the form being only one-to-one interview, and the like. Other common clinical depression discrimination and diagnosis methods include other scales (e.g., hamilton depression scale) and self-scales (e.g., depression self-scales, beck depression scale, etc.), which are currently the most widely used methods for large-scale screening. However, the self-assessment scale is mainly dependent on subjective reports of individuals, has a certain limitation, may be hidden deliberately, has deviation in self-cognition and the like, and has an unsatisfactory assessment effect on patients with low cultural level or poor mental level.

And S006, a risk proportion threshold is arranged in the depression risk assessment module, and each tested depression risk grade in the group is divided into high risk, middle risk and low risk according to the proportion R and the risk proportion threshold which are obtained and meet the condition indexes and is output.
Preferably, the risk proportion threshold is set to a and b, when the resulting proportion R satisfies: b > R > a, the corresponding risk of depression tested is risk of stroke; when the ratio R satisfies: when R is more than or equal to b, the corresponding tested depression risk is high risk; when the ratio R satisfies: and when R is less than or equal to a, the corresponding tested depression risk is low.
For example, in fig. 1, when a is 30% and b is 70% and less than 30%, the tested person is considered to have a low risk of depression, when the value is higher than 70%, the tested person is considered to have a high risk of depression, and when the value is within the range of 30% -70%, the tested person is considered to have an intermediate risk. Of course, the values a and b are not limited to the values given in the examples, and can be further adjusted according to the characteristics of the population data.
The invention adopts standardized task and data acquisition flow, and the indexes acquired in each task stage have definite dividing standard and threshold, so the implementation difficulty is small, the automatic stimulus presentation and data acquisition are supported, and the operator does not need to have psychology related professional knowledge. And the method is carried out in a group data acquisition mode, so that the method is high in acquisition efficiency, fast in output result and suitable for large-scale popularization in different fields.
The invention is applicable to the prior art where nothing is mentioned.
