The theory of self-value orientation is a psychological theory about the relationship between attitude and behavior. The theory holds that under the condition of relatively stable external environmental pressure, the consistency between an attitude and a specific behavior, or its influence on a specific behavior, depends on whether the attitude itself is at the center of the personal value system and whether it has special significance to individuals. The higher the moderate attitude, the more important the relevant behavior is to the individual, and the greater the psychological impact on the individual, so this attitude has a greater impact on the behavior. The founder of this theory is Dr. Jin Shenghua, a professor at Beijing Normal University. In the early 1990s, Professor Jin formally put forward the theory of self-value orientation when he was studying for his doctoral thesis, and based on the hypothesis of self-value orientation principle, he introduced the model of "self-value dependence-loss-suicide theory". The purpose of self-value determinism of this kind of behavior is to find the psychological mechanism of explaining, predicting and controlling behavior.
