The questionnaire on college students’ optimism contains 13 items, including two high-order factors: optimism and pessimism. Optimism includes optimistic expectation and optimistic explanatory style which pessimism factor includes pessimistic expectation and pessimistic explanatory style. The fitting indicators are better (X2/df = 3.45, GFI = 0.96, IFI = 0.95, NNFI = 0.93, CFI = 0.95 and RMSEA = 0.06), internal consistency reliability is between 0.61 and 0.74, and all sub-dimensions of the questionnaire are significantly correlated. The total scores of the questionnaire and four factors are positively correlated with the total scores of the life orientation questionnaire (0.74 ∼ 0.81). The college students’ optimism is composed of four factors; the reliability and validity meet the requirements of psychometrics, and can be used in related research and practice. This study seemed to show that the CSOQ was a valid tool for measuring optimism among Chinese college students.
