Optimism, as a kind of steady personality, is the positive tendency of individuals towards the reality and the future. At abroad, the research of optimism personality is very fruitful in the field of theory and application, but the study of conclusions of the structure of optimism, the relation among optimism personality, psychological health and work results and the mechanisms of their interactions were not consistent. Research on optimism is just on its starting stage in China. Therefore, we need to explore the structure and intension of optimism under Chinese cultural background, and do some concrete research to find interpretations on the correlation among optimism, psychological health and work results.538 college students and petroleum industry staff participated in the first round of test,801 petroleum industry staff in the final round.
