Stockholm syndrome, Stockholm effect, also known as Stockholm syndrome or known as hostage complex or hostage syndrome, is a complex in which the victim of a crime becomes emotionally attached to the perpetrator and even helps the perpetrator in turn. This emotion causes the victim to become attached to the perpetrator, dependent on the perpetrator, and even assist the perpetrator. Hostages develop a sense of psychological dependence on their abductors. Their lives and deaths are in the hands of the abductor, and they are grateful when the abductor lets them live. They share the fate of the hijacker, taking the hijacker’s future as their own, taking the hijacker’s safety as their own. Thus, they adopt the attitude of “we are against them” and treat the rescuers as the enemy. Clinical manifestations According to psychologists, people who are emotionally dependent on others and easily moved are prone to Stockholm syndrome if they encounter similar situations. 2, in the process of being held hostage, the hostage must recognize the kidnapper (perpetrator) may be a small act of favor. 3. The hostage must be isolated from all other points of view except the single view of the kidnapper (usually no information from the outside world). 4, the hostage must believe that it is impossible to escape. These four conditions give rise to Stockholm syndrome. Diagnosis Usually Stockholm syndrome will go through the following four major processes: 1. fear: because of the sudden coercion and intimidation caused by the current situation change. 2. Fear: The monopoly on the environment of anxiety and threat to both body and mind. 3, sympathy: and the hostage for a long time to get along with each other to realize that the other party had no choice but to act, and did not suffer “direct” harm. 4, help: to give the hostage intangible help such as cooperation, do not escape, reassurance, etc.; or tangible help such as assistance to escape, to the judge, together with the escape, etc. Treatment The best treatment for Stockholm syndrome should be to find a psychiatrist for psychotherapy. Treatment of Stockholm starts with helping the victim to understand himself or herself and developing the victim’s personal potential. Then help the victim to develop a positive mindset, not to easily give in to reality, and to understand the weaknesses of the perpetrator and wait for an opportunity to launch a self-defensive counterattack. Finally, it is important to establish a system that limits the perpetrator’s evil.
