What are the psychological characteristics of suicides before they commit suicide? Suicides have common psychological characteristics before committing suicide, as follows: ① Most suicides are in a contradictory state of mental activity, in the contradiction of wanting to get rid of the pain of life as soon as possible and the desire to live. “To live or to die?” They are indecisive. At this time, they often mention the topic of death or suicide. They don’t really want to die, but want to get rid of the pain. ② Suicidal behavior is actually an impulsive behavior that, like other impulsive behaviors, is triggered by negative daily life events and often lasts only a few minutes or hours. ③ Suicidal people are clearly rigid in their thinking, emotions, and actions at the time of suicide. They often view everything in terms of pessimistic preoccupations and refuse and are unable to consider alternative solutions to their problems. What are the clues of a suicidal person? The occurrence of suicidal behavior is not entirely sudden and unpredictable; there are certain clues to the occurrence of most suicidal behaviors that can be analyzed and assessed to improve the prediction and prevention of suicidal behavior. The basic clues for suicide risk assessment are: 1. Those who have expressed their suicidal intentions through various ways of expressing negative and pessimistic emotions. Suicidal people have shown considerable signs of having expressed suicidal intentions in their own way before committing suicide, such as repeatedly asking or talking to friends, relatives, colleagues, or medical personnel about suicide methods, and frequently talking about suicide in their personal diaries and other works. In addition, reluctance to discuss suicide with others and intentional concealment of suicidal ideation is also an important red flag. 2. Recently suffered a serious and irreparable loss. “Although the risk of suicide decreases after crisis intervention, the desperate will may still make them take suicidal action. When they “get used to it”, the risk will gradually decrease. 3. The likelihood of reoccurrence of suicidal behavior is very high when there has been a recent self-injury or suicide attempt. Past behavior is the best predictor of future behavior. After a patient takes suicide and does not really solve his or her problem, the risk of committing suicide again will be greatly increased. In addition, after repeated suicidal behaviors, people around the patient often think that the patient does not want to die and let down their guard, and the success rate of suicide will be greatly increased at this time. 4, personality changes occur, such as irritability, pessimism, depression and apathy, introversion, withdrawn behavior, not interacting with family and friends; the emergence of self-hatred, feelings of guilt, worthlessness and shame, feeling lonely, helpless and hopeless; suddenly organize personal things or write personal will; a family history of suicide, etc. Suicide attempts, both to assess the risk of suicide, but also to make them experience care, support and understanding, and reduce the risk of suicide. 5.Patients with chronic refractory physical illness suddenly do not want to accept medical intervention, or suddenly appear “abnormal” mood improvement, with friends and relatives to explain the future arrangements and intentions of the family. Patients with mental illness, especially depression, schizophrenia, alcohol and drug dependence, are recognized as a high-risk group for suicide. Those with symptoms such as self-blame, victimization, delusions of grandeur, or command hallucinations, compulsive thinking, anxiety or panic-stricken people. Patients with depression should be alerted to the possibility of suicide if there is a sudden “improvement” in mood. In a follow-up survey of depressed patients, it was found that 42% of 36 patients committed suicide within 6 months of discharge, 58% within 1 year of discharge, and 70% within 2 years. Thus, suicide in depression does not necessarily occur only during the peak of the illness, but also during the remission period when the risk of suicide is high.
