An important means of psychological diagnosis is psychological testing. Physical phenomena and physiological phenomena are measurable, and psychological phenomena are measurable. For example, the weight or length of the object can be measured or measured with a ruler, the blood pressure of the person can be measured with a sphygmomanometer, and the memory of the person can be measured with a memory meter. Of course, the measurement of human psychological phenomena has its own characteristics compared with the measurement of physical phenomena and physiological phenomena. There are many types of psychological tests. According to a survey conducted by American psychologists in 1961, there are nearly 3,000 psychological tests. But as far as its classification is concerned, there are only a few types. From the purpose of the test, it can be divided into intelligence test, personality test, special ability test and so on. From the content of the test, it can be divided into text test and non-text test. From the form of the test, it can be divided into individual tests and group tests. From the method of testing, it can be divided into questionnaire type test, work type test, and projective test. There are many types of personality tests. Currently, the Minnesota Multiphasic Personality Test (MMPI) is popular in the West. The Minnesota Multiphasic Personality Test is a wide range of subjects, consisting of 566 questions, including health, psychosomatic symptoms, neurological disorders, and dyskinesias; Sexual, religious, social and political attitudes; issues of education, occupation, family, marriage, etc.; various abnormal behaviors such as obsessive attitudes, compulsive behaviors, hallucinations, fantasies, sadism and masochism.

(three) reactive obsessive-compulsive disorder

Under the influence of strong obsessive-compulsive factors, the patients may have visual hallucinations and auditory hallucinations. The content is related to obsessive-compulsive factors. The patients show fear and anxiety. When the obsessive-compulsive factors are eliminated, the symptoms disappear quickly.

(4) Obsessive-compulsive disorder

In addition to association, affective disorder, and decreased will, patients with obsessive-compulsive disorder have hallucinations in more than half of the patients. The most common is auditory hallucinations, mainly speech-based auditory hallucinations. When a patient hears a neighbor, a relative, a colleague, or a stranger, the content often makes the patient unpleasant. It is characterized by hearing two or more voices talking about the patient, quarreling with each other, or commenting on the patient in a third person. Some voices often threaten to command patients. If the patient is not allowed to eat, let the patient die, etc., or talk about the patient's thoughts, comment on the patient's behavior, the patient's behavior can be affected by auditory hallucinations.
