The achievement motivation scale (AMs) was compiled by psychologists T. Gjesme and R.Nygard of the University of Oslo in Norway in 1970 and revised by Ye Renmin and Hagtvet (1955). The reliability and validity of the two scales are: =0.77 and: =0.58, respectively. According to the theory that achievement motivation has positive and negative expected results, the scale includes two distinct sub-scales: one is to measure the motivation Ms related to success, which involves the expectation of positive evaluation situation and results, and the other is to measure the motivation M related to preventing failure. From the content, people with high Ms yearn for success, actively pursue success, have self-confidence, want to exert their potential and intelligence, are willing and dare to take risks, dare to challenge difficulties, don't care about external performance and praise from others, and are not afraid of failure; On the other hand, people with high Mf treat success negatively, attach importance to and avoid possible failures, are sensitive to uncertain situations, things and unstable States, are prone to anxiety, do not attach importance to exerting their potential, and dare not pursue difficult tasks. The two subscales each have 15 questions and ***30 questions, and are scored on a 4-point scale. AMS is selected and filled in by the subjects themselves, and their understanding and attitude are answered according to the content of the questions, and the explanations of the questions are selected in four grades according to the degree of approval (from "completely correct" to "completely wrong"). The more you agree with the content of the scale, the higher the score, and the higher the motivation level Ms and Mf respectively. When Ms is greater than Mf, the overall motivation level of pursuing success is relatively high, while when Ms is less than Mf, the motivation level of pursuing success is relatively low, and individuals tend to avoid failure.
