Comparison

Individuals can feel different from the past, such as experiencing depression, unhappiness or depression, and feel pain, and need to seek help from a doctor. Or if the observer observes that the patient's behavior is different from the past based on his own experience, it can be considered abnormal.

2. Changes in the nature of psychological activity

If obvious qualitative changes in the patient's mental activity are observed, such as hallucinations, delusions, obvious language disturbances or behavioral abnormalities, it is suggestive of a psychological disorder.

3. Social adaptation barriers

Human behavior is always in harmony with the environment. If an individual is suffering from social maladjustment, it may reflect that his psychological activity may be abnormal. However, people's social adaptation behavior and ability are affected by factors such as time, place, culture, customs, etc. Therefore, social adaptation standards must be determined according to specific circumstances.

4. Statistical standards

According to statistical standards, people's psychometric results are normally distributed, and most people in the middle belong to the normal psychological range. This is regarded as "abnormal" at both ends. Therefore, to determine whether a person is psychologically normal or not depends on the average level of deviation from the normal person's psychological characteristics. That is to say, a psychological activity is normal if it is owned by most people under the same conditions; it is abnormal if it deviates from the general level of most people. Different psychometric techniques have been devised to determine different psychological characteristics. According to the comparison between the measurement results of an individual and the measurement results of the normal population, normal and abnormal Hu critical states can be distinguished, such as IQ: below 70 is considered abnormal; 70-90 is considered critical; above 90 is normal. In addition, some scales used in the clinic are also designed using similar principles, and the results can be used for clinical reference.

5. Symptoms and etiological criteria

Symptoms and etiological criteria treat mental disorders as physical illnesses. If a person exhibits a certain psychological phenomenon or behavior and can find pathological anatomy or pathophysiological changes, it is considered that the person has a mental disorder or a net disease. If a drug has a toxic psychological disorder, it can be judged based on the existence of a certain drug. At this time, physical, chemical inspection and psychophysiological measurement are of great significance.

Diagnosis of mental disorders

According to the cause, clinical manifestations and related examinations can be diagnosed.

Differential diagnosis of psychological disorders

It is often difficult to correctly distinguish between normal and abnormal psychological activities for four reasons:

1. A person's psychological activity is invisible, and the process of his psychological activity can only be inferred from the individual's speech and behavior.

2. Psychological activities are affected by a variety of factors such as environment, interpersonal and socio-cultural relationships, as well as speaking and behavior.

3. Individual differences in psychological activity are large.

4. There is no clear demarcation between normal and abnormal mental activity.

Therefore, there is only one aspect of abnormal mental activity that is not necessarily a psychological disorder; the diagnosis of psychological disorders needs to meet certain standards, and the individual feels pain or significantly affects his social interaction or professional function.
